 precisely to GE factory specifications, the reward is $10,000 !!!!!


G.E. is a huge conglomerate with a large number of talented professionals. The engineer who designed Nautilus Toco transducer 2264 LAX/HAX is certainly a genius. It is a transducer very sleek in design and employs latest technology that ensures very consistent performance over years. The PCB is miniaturized with 100% SMD components making it extremely light in weight, thus providing comfort to the would-be mom when monitored for contractions over long periods. Size, shape, very efficient utilization of space for component assembly and circuit design considering every minute detail, makes these units very unique.

GE’s price for the Nautilus transducer is reasonable as compared to the predecessor transducers that were strain gage based. This price is reasonable when compared to the other manufacturer’s cost. Not only the initial purchase cost is low but expenditure on maintenance over a period of time is also significantly low if the Nautilus transducers are repaired retaining original GE parts and following OEM procedure. The problem starts when original Nautilus transducers are sent for repairs to a third party company that uses Non-GE (Non-OEM) parts and follow just one single step to test as per the GE's field service manual.

First thing to take into account is the fact that Non-GE parts cannot be used in place of original GE parts (such as PCB assembly) that are critical for the compliance to published GE specifications and approved by FDA.as Corometrics Nautilus Toco transducer 2264 LAX/HAX. 

Let us say hypothetically that the non-GE, clone/imitation circuit board functions exactly as original PCB from GE; even then, it cannot be used in place of original GE PCB in the original GE transducer for compliance to GE specifications.

The moment any part is non GE, the resultant transducer is no more GE Nautilus transducer 2264 LAX/HAX technically, it can not be labeled as "GE Corometrics Nautilus 2264 LAX/HAX" and hence does not have FDA approval as “GE’s 2264 LAX/HAX”. The Nautilus transducers with some original GE parts and some non-GE parts, GE will not take responsibility or liability, nor will the the replacement circuit board manufacturer from overseas will cover any liability. More interestingly, the third party service company’s liability insurance carrier will also not cover such a device with partial non-OEM parts including the the critical circuit board assembly under their insurance policy. If a third party service provider claims that their use of non-OEM parts is compliant and backed by their liability insurance carrier, it has to be put in writing on certificate from the insurance carrier and verified by the hospital’s insurance carrier. To make this point clear, if you sent your Mercedes car to a dealer for repair and what you get back is the Mercedes body but the engine replaced by a clone/imitation engine manufactured by Huachua from overseas and not the original from Mercedes factory (though it looks like Mercedes engine), this modified car is neither Mercedes nor Huachua and both these companies will not be responsible for any safety issues nor liability as the assembled car has not rolled out either from Mercedes or Huachua factory. You are not even aware of the fact that your car does not have original Mercedes engine anymore. If an accident occurs and you call your insurance company and provide them the VIN number which is now Huachua’s engine number, you will get enlightened that your insurance company either cannot help you as it is not the compliant vehicle anymore. The ‘new’ car with Mercedes body and Huachua engine needs to go through all the safety and approval tests and once passed, it can be launched by the car service dealer as a another model which is neither Mercedes nor Huachua’s model number. Let us call this new car model as Merchua. The new Merchua model of car now has perfect standing for safety, compliance but Mercedes has to agree to allow use of their car body for Merchua! Why would Mercedes do that and help competitor to rise?  

Big question at this stage is – doesn’t client deserve to get back his original Mercedes with original engine? If at all engine needs replacement, it has to be another unit from Mercedes in order to comply by regulations. Thus, is it not unethical and unprofessional to replace OEM circuit board from the OEM transducer with non-compliant, substandard, poorly performing clone/imitation circuit board without client being informed? For OEM compliance, original GE parts cannot be used to repair third party manufactured transducers termed as compatible to GE transducer, nor can non-GE parts (manufactured for compatible transducers which has FDA approval to be used in place of original GE/Philips transducer) be used as replacement parts to repair original GE transducers unless the third party service company guarantees in writing that repaired items with partial non-OEM parts, will perform 100% to OEM specifications and their liability insurance carrier endorses it.

Nautilus Toco transducers process extremely low potential signals. The output from transducer to fetal monitor is in the range of 100 micro-Volts to few milli-Volts that is susceptible to noise. The ultrasound transducer output is always in micro-Volts and is far critical. Take a brand new original GE Nautilus transducer that has all original parts from factory and working perfectly.. Have it's function verified as per service manual and reconfirm that GE factory has not shipped faulty transducer or during shipment, some problem developed due to impact or weather factors. The next step is to cut the connector off the cable and send this transducer to one of the third party to put molded connector on it. The original connector from GE has rubber boot over hard plastic carriers that hold the white/gray round housing with spring loaded contact pins that are gold plated. A third party molded connector is usually made by first crimping contact pins on cable-conductors, then holding these pins in a tool and pouring liquid plastic, like an encapsulation process. 

Being molded permanently, the pins do not move and do not aid smooth mating with plug-on monitor as compared to original GE connector. Over short span of time, the base line of Toco contraction waveform starts drifting. This happens due to varying leakage current between contact pins through plastic that is used for the molding. If the transducer is left powered on with fetal monitor for days, the contraction waveform shows intermittent spikes as if contraction is taking place though there is no pressure applied on the transducer’s diaphragm. The original nautilus Toco transducer though has all brand new original GE parts except the third party molded connector, does not perform exactly as another brand new GE transducer. Try using third party manufactured cable-connector (molded) assemblies from various vendors on brand new GE transducer and you will see the base line drift with intermittent spikes of false contractions. Any clinical professional would agree that this is definitely a major issue. The key is to test the transducer (repaired using cable-connector assembly from the third party vendors) by leaving it powered on with the monitor for minimum 72 hours. This test is not mentioned in GE's manuals. GE’s service manual stipulates placing a 52.5 gm weight on Toco diaphragm and checking the Toco count with CMR voltage reading. When third party vendors replaces cable-connector assembly and do this single test without paying attention to CMR voltage level, all transducers pass the test successfully but perform poorly when used continuously at hospital. In case of Nautilus Ultrasound transducer 5700 LAX/HAX, use of molded-in Non GE connector causes spurious fetal heart rate spikes more than 220 BPM though the actual fetus heart rate is normal in the range of 140 BPM. This is certainly a matter of concern to clinicians. 

The use of Non GE molded-in connectors, though just one single part, results Nautilus transducers performing poorly and pose great probability of misleading interpretation of contraction as well as the fetal heart rate tracing. Over a period of time, transducer goes through repeated repairs by third parties and when the original circuit board gets replaced by a clone PCB assembly, the transducer turns out to be crap physically as well as functionally.

Replacing cable-connector assembly on Nautilus Toco transducer is a very easy job but calibrating it is extremely tedious process requiring several attempts by assembly and dis-assembly of top-bottom casings. If GE’s calibration procedure is followed strictly ensuring CMR voltage is adjusted within +/- 40 mV (0.040V) tolerance and cable assembly used is original GE part (P/N 2003662-001, $202.46) or at least the original GE connector is re-used then the transducer functions exactly to GE factory specifications and its performance will be consistent over a significant length of time. If the calibration of CMR voltage tolerance and level is compromised to achieve a quick fix and even though the transducer has 100% original GE parts including the cable-connector, it will not function to specifications and base line will drift in a short span of time. Third party repaired transducers with molded-in cable-connector are never perfectly calibrated as per GE’s procedure outlined in the GE document # 2003704-001.

GE/Corometrics Nautilus Toco transducer, if opened just for calibration during routine maintenance, the GE procedure stipulates discarding old flat-seal O-ring and all 5 screws that are used to assemble top-bottom plastic cases. While assembling, the ‘torque wrench’ need to be used with specific settings. This is extremely important as the PCB has SMD components. CMOS based IC chips have lead spacing of less than a millimeter and passive components have lead spacing of barely a millimeter at the most. If moisture, dust, body fluids or any other foreign particles get inside the transducer, the overall performance suffers greatly with the base line jumping all over the tracing paper with spurious and misleading signal recording. G.E.’s instructions for replacement of flat-seal O-ring, screws (that also have o-rings) and specific Torque setting during assembly is to ensure weather protection in normal usage. This protection parameter is far more critical if the transducers are used with fetal telemetry and the would-be mom takes shower. There are detailed instructions in manuals for use with fetal telemetry system, cleaning and overall handling for these original GE transducers. Under no circumstance should the Nautilus transducer be submerged in water or any other liquid and the would-be mother should not get into bath tub with transducers strapped. GE does not recommend using fetal monitor with transducers for under water deliveries and expecting moms should not get into bath tub with Nautilus transducers strapped on belly and NEVER connect with AC POWERED-on FETAL MONITOR for SAFETY compliance.

 

This weather protection factor can be verified with a simple test of blowing dry hot air, highly humid air, and cold air alternately directly onto the exposed PCB of a working Nautilus Toco transducer while observing CMR voltage reading, Toco count recording on fetal monitor and comparing those results. 

The feature of being 'watertight' for Nautilus Fetal transducers is to provide protection to SMD based PCB against moisture to avoid spurious performance. It does not mean being watertight is an advantage for Nautilus transducers for application involving under water usage. In fact, 'watertight' is not a feature at all, rather it is a requirement for Nautilus transducers in order to function correctly. So it is fair to say that this environmental sensitivity of Nautilus transducers is the major weakness as compared to predecessor models of GE transducers as well as some competitors' transducers. Clone PCBs used by the third party companies are manufactured without considering precise design requirements including the moisture sensitivity and turn out to be absolute waste. Any liability insurance carrier, whether it is hospital's insurance policy or a third party service company's insurance policy, will not cover a OEM medical device being repaired by replacing a cloned non OEM circuit board (PCB) assembly as it is critical for functionality to exact OEM specification. If this practice is allowed, imagine what would happen to commercial passenger aeroplanes fitted with generic cloned engines that are not from the respective original manufacturer? 

 

Third party manufactured plastic Top-Bottom casings do not match in dimensions and weather protection (water-tightness) cannot be ensured leading to poor performance based on changes in air moisture level. Transducers with non GE plastic casings pick up heavy moisture when used with telemetry systems. Moreover, these casings are manufactured using low grade resin and do not pass mechanical, electrical as well as environmental tests performed at GE factory and their vendors. That means these plastic parts crack and break with relatively very low impact force as compared to OEM plastic parts. Some third party made Bottom casings have extremely hard diaphragm that do not detect weak and medium strength contractions. Some non-OEM bottom casings have ultra thin and delicate diaphragm through which hygroscopic ultrasound jelly enters inside making SMD circuit board (PCB) behave sporadically that causes false spikes of contractions.

Changing sub-standard quality plastic casing is also a very quick job as the focus is not to achieve perfect calibration. General repair that requires cable-connector, plastic casings replacement takes less than 10 minutes and parts cost less than $4 in total if they are non-OEM. Such repair work can be performed by a person who is not even high school graduate. More troublesome is when Toco circuit board (PCB) failure. PCB being SMD based requires highly skilled, well experienced technician to repair it on component level. It is extremely rare to get such a person who is also efficient to reduce repair time to make an economically viable repair work. Some Third party companies try to glue SMD components on PCB using cheap epoxies/adhesives which is absolutely against the norms and industry standards. The epoxy, adhesives poured on circuit board create complex stray RLC (resistor, inductor, capacitor) network between SMD components as well as PCB tracks and modify the whole circuit that does not perform to original design specifications. 

The nut and other metal hardware components are made (by third party) from Aluminum in place of stainless steel. The nut and strain reliefs are also heavily glued. There is silicon pored all over inside the bottom case.  This is extremely poor workmanship and absolutely non-compliant process that poses danger if chemicals/glue come in contact with body fluids. The transducer does not work to OEM specifications and keeps coming back within few days to couple of weeks, gets charged repeatedly for repair and the sales guys tell biomed technicians that the clinical staff/nurses abuse them and is the only cause of repeated failure. If a careful tracking system is in place, we can find that original GE transducers definitely last more than 2 years with proper handling. In same situation, the third party repaired transducers fail repeatedly in very short span of time costing more money than replacing new one from GE.

In the event when Glue fixing does not work at all, the whole PCB assembly is replaced with a clone PCB that looks same as original but does not perform to OEM specifications. PCB track impedance vary, the components used are of cheapest quality and of values far different than original PCB. Many of these non GE PCBs have few jumper wires to bypass some circuit sections to make Toco count go up SOMEHOW when 52.5 gm weight is placed on the diaphragm. As no single parameter is right (including signal to noise ratio) with the replacement PCBs, Toco transducer gives spurious/intermittent contraction waveform even when there is absolutely no contraction.

Interestingly, many third party companies disassemble circuit board (PCB) with bare hand from the bottom case of original Nautilus Toco transducer in order to replace cable-connector assembly. Though the original PCB did not have any problem, due to technician’s handling with bare hands without static protection strap, many SMD capacitors’ dielectric breaks down with high voltage static discharge. These capacitors become leaky and cause annoying fluctuation of transducer's output. These 'repaired transducers' are shipped as they are and keep coming back for frequent repairs which are invoiced. Very rarely do biomed technicians track the repairs and point them out to the service company and then they replace the OEM PCB assembly with CLONE/IMITATION PCB with some modifications and jumpers.    

The simple test of putting 52.5 gm weight 3-4 times on diaphragm and taking Toco count does not ensure that the REPAIRED transducer is functioning absolutely well within OEM specification. Specific test jigs and extensive number of tests/checks are required such as CMR Voltage drift, noise rejection, sensitivity, ultrasound beam profile, beam focal point, total power radiated per sq. cm, sensitivity of individual crystal, error factor in beat detection, spectrum analysis of received signal etc. These extensive tests are done at GE factory and are not detailed in any of their field service manuals. The single test mentioned in the GE service manual is applicable only when a OEM transducer with 100% original parts and never attempted for repair, is being evaluated. It is extremely important to note that the GE's manual does not state that the the test-calibration procedure of using 52.5 gm weight (just one single step) is the only check/test that need to be performed after repair of the Nautilus Toco transducer 2264 LAX/HAX. At GE factory, when they have to repair Nautilus Toco transducers, it is certain that they are doing more than 9 different tests and checks to ensure first the PCB assembly is perfectly functional and then after fixing that repaired PCB assembly in a bottom plastic case is when the 52.5 gm weight is used for final check-calibration. It is not the adequate test protocol to certify repaired OEM transducer (with 100% original parts) or a transducer repaired using cloned PCB as functional to OEM specifications.

There are many companies claiming to manufacture GE compatible Toco and Ultrasound transducers. Most of these compatible transducers and parts are sourced from overseas. No matter where the origin is, all these compatible transducers have substandard quality parts that if tested individually with appropriate factory protocol, do not match with original parts from GE and complete transducer assembly does not perform as good as original GE transducer. The cost of repeated failures, poor performance, spurious false pick up of contractions and high heart rate, downtime, cost of repeated administrative process of shipping/generating purchase orders etc. is not worth the end product. Most of these ‘compatible’ substandard transducers are switched in place of original GE transducers when received for repairs by third party companies in order to claim fast turnaround time. In most instances, they do not come with written guarantee for performance to GE specifications and as ‘non-OEM’ are not covered by liability insurance carrier in USA/Canada. Most of the compatible transducers produced overseas do not have US FDA approval. 

That is why on-line (Internet) sale of such transducers and individual parts is very deceiving. One should insist for proper documentation if hospital wants to be compliant with laws and regulations as well as provide quality care for patients. In real life, a genuine Mercedes is never sold at the low price that Huasong charges for its car. However, it is possible to get your Mercedes car serviced by a competent individual or his organization at lower cost without any compromise in quality as well as keeping compliant to all regulations. Here, lower cost means lower than what a Mercedes OEM outlet would charge. This competent individual or organization is knowledgeable, experienced, ethical professional who uses genuine parts from Mercedes and follows standard laws and regulations. The difference between Mercedes service center and such a person or organization is better efficiency and lower operating cost due to effective utilization of resources. Cost reduction is achieved by innovative technique for quality process, test jigs, specialized tools which results in significant reduction of total time taken to repair a device (compared to OEM rather than comparing with practice of quick switching by clone device) and that saving is passed on to the client.

Original GE Toco and Ultrasound transducers (all models) after going through repair process at third party companies (that use non-OEM parts) start deteriorating after each instance of repair, it gets worst and worst with non GE parts, glueing process and become a real junk in a short span of time.

Is it possible for a USA-based third party company to produce perfectly compliant GE compatible transducers with equal or exceeding performance parameters? The answer is YES but it is not economically viable. GE produces parts in millions and long-standing relationship with their vendors as well as advantage of paid up investments of basic set up/tooling being in business for a long time, enables GE to achieve much lower cost factor. Third party vendor can only aim at some proportion of the market share and cannot go on investing on millions of parts in a single production cycle.The lower the volume of parts, higher is the production cost per unit. Moreover, the basic development and set up cost will also be much higher for quality processes compared to GE. These non-OEM parts, if remain in inventory for a longer length of time then higher is the cost to the third party by way of paying interest on basic investment. The only advantage for the third party would be lower cost of employee wages compared to GE. Overall, each part’s production cost would be much more than what GE achieves through their manufacturing process. Most important thing to understand is that many of the key parts manufactured by OEM's vendor are just-in-time supply that significantly eliminates production associated investment on the part of the OEM. For a third party service company to make economically viable parts' production run, first thing needed is to grab at least 80% of the market share that OEM has gained. The 'compatible' fetal transducer with 100% Non GE parts but functioning to exact GE specification would cost little over 2 times more than what GE charges for their brand new units.

Averon Bionics is Atlanta based superior service company that guarantees OEM quality repairs. If client sends in original GE/Philips transducer for repairs, it will be repaired keeping original parts intact and will function exactly to OEM specifications. Generally, transducer repaired by Averon will perform better than brand new ones from OEMs. In case of doubt, client is encouraged to send Averon repaired OEM transducer to GE/Philips for testing and if it is reported to be not functional to exact OEM specifications, Averon will pay for the cost of testing at OEM factory, reimburse the client to buy a brand new transducer from OEM and there will be no invoice sent for the repair that did not conform to OEM specifications as well as overall performance. Please note that OEM testing cost at GE/Philips factory will be more than the cost of a brand new OEM transducer as the labor charge is more than $240 an hour. This fore mentioned absolute guarantee promise in writing, has any biomed technician ever got it from any other third party service company in black and white?

Averon Bionics is a professional outfit with ethical business practices, honesty and integrity and is the only company in North America with full capability to repair Philips wireless fetal transducers M2725A, M2726A used with Avalon fetal monitors. Averon has developed proprietary processes to enhance quality and durability of repaired transducers so that they can offer fabulous 5 year’s warranty on crystal bonding of rebuilt fetal heart ultrasound OEM transducers and 2 to 5 years overall warranty on OEM transducer repairs at a  reasonable charge compared to OEM cost

For cost savings, some purchase managers choose repair services of third party that uses non-GE (non-OEM) parts. Such flat rate repairs costs in the range of $90 per unit and Averon can repair these units keeping all those non-OEM parts as they are, bringing them back to the same non-OEM performance for as low as $49. Purchase managers just need to mention on the hospital letterhead that they have a certificate from the previous service company who used non-GE/Philips parts, repaired transducer with non-OEM parts is compliant to all existing regulations, liability insurance carrier of the service company has authorized use of non-OEM parts for repairs of OEM transducer with liability coverage and the insurance carrier of hospital has also acknowledged that hospital is compliant using those repaired fetal transducers (with partially non-OEM parts) on patients. This means the purchase manager needs to request for a written compliance statement/certificate from the third party who used non OEM circuit board assembly/parts in hospital's OEM transducer while repairs.

In case, the hospital is not able to obtain a compliance certificate from the third party company that used the non-GE/Philips parts to repair transducers and  purchase manager still wants to continue using those repaired transducers with non-original parts, Averon will send an evaluation report giving details of transducers with non-OEM  parts. The purchase manager needs to acknowledge our evaluation report with instruction to us to keep all non-original parts as they are and bring transducer back to same performance as it showed when received from the previous repair company, further stating that hospital has all relevant documents (quote, invoice, delivery note, shipping tracking records, payments etc.) to trace the use of non-original parts in OEM transducers establishing the fact that responsibility of liability arising out of using non-original PCB/parts lies with that third party company which substituted non-OEM PCB/parts in place of original PCB/part. We will have to spend time for evaluation as well as documentation and still the repair cost of $69 per unit will be significantly low compared to the third party's flat rate repair charges for the transducer that they had previously repaired using non-OEM parts. Point to be noted is that Averon Bionics will not be responsible for the liability issues arising because of non-OEM parts used during previous repairs by another third party service company.

Averon guarantees 50% of cost savings whether the transducer is original or non original. For instance, if the hospital is offered lower price than $49 from their current third party service provider who uses non-original parts, just send us a copy of the quote/invoice and Averon will give 50% discount against it. If the current third party service company quotes $40 against Averon's quote of $49 then after verifying that quote/invoice, Averon guarantees to cut it down by 50% so that the repair charge per unit becomes $20. For OEM quality, the comparison has to be with the prices from GE/Philips. Most important point to note is that Averon offers 2 years warranty on repair of original transducers that are never sent to any other third party company and guarantees performance exact to OEM specifications with 50% cost savings as against going back to the respective OEM (GE/Philips) for repair or replacement. 

While purchasing a compatible transducer, medical device, accessory or individual non-original parts for replacement in a OEM medical device that is governed by regulatory agencies such as FDA, Joint commission etc., directly from the third party supplier or on Internet, one has to be careful to check out all documentation – compatible model number, serial number, manufacturer’s name, country of origin, FDA approval number, compliance certificate and asses the overall quality for consistent performance as well as durability. Ultimate responsibility for liability lies with one who puts such a device on patient and causes unnecessary C-Section delivery or that sort and that is hospital administration. There is no single compatible transducer available in the market that will perform precisely as brand new GE Nautilus Toco 2264 LAX/HAX. You will never be able to calibrate a compatible unit to Nautilus Toco 2264 LAX/HAX very accurately using GE’s procedure outlined in document # 2003704-001. 

Any hospital biomed technician who shows that GE Nautilus Toco transducer 2264 LAX / 2264 HAX with non GE PCB assembly and non original bottom plastic case can be calibrated precisely as per GE document # 2003704-001 and tested for performance leaving powered on with fetal monitor for at least 72 hours continuously, further demonstrating that the base line does not drift more than +/- 2 counts as well as the CMR voltage reading remains constant within the tolerance limit of +/- 40 mV (0.040 V), will be given a reward of $10,000 from TocoXpert !!!!!!

Never get carried away by sales representatives' verbal claims and counter claims from various third party companies. The simple and logical approach is to write to all third party companies and request written compliance certificate on the company letterhead and have insurance carrier issue endorsement for use of non-OEM PCB/parts with liability coverage. Third party companies who put that in writing, are worth evaluating for their service quality. Send 4-5 units to all these companies (who have issued written compliance certificate) for repairs. Perform testing of repaired items for 8-10 days with close watch for performance by the end users, document results properly and compare with brand new OEM units. It is worth even to have third party repaired transducers tested once from OEM and obtain report. You will know from your own test results as to which company's claim stands good. Never get played by sales people and blame the end user nursing/clinical staff. Always check all third party repaired devices every time thoroughly.

Non-OEM on Left that has original GE plastic top case. Original GE Nautilus Toco Transducer 2264 LAX on right with GE factory labels.







Non OEM on RIGHT (Below Picture) with very hard diaphragm, non GE bottom plastic case, non-GE molded connector used by third party service provider to repair original GE Corometrics Nautilus Toco 2264 LAX / 2264 HAX.



Non GE on Right with cloned PCB that has jumper wires to bypass some section of circuit. The difference in workmanship and quality is vary obvious as the picture SPEAKS for itself! On Left, is the original GE Corometrics Nautilus Toco 2264 LAX/HAX transducer with all original GE parts. The connector of the third party repaired Nautilus Toco looks very deceiving as if it is original from GE but it does not! It is a over-molded HARD connector without rubber boot that does not perform exactly as the original G.E. Corometrics connector as there is varying leakage current between the contact pins through plastic resin used. These molded connectors from various third party service companies, do not match precisely in dimensions with the counter part (female) plug-connector on GE FETAL MONITOR. As a result, the female connector on fetal monitor starts accumulating Brass particles from molded connector's contacts and the pins start loosening due to excessive stress that adds to 'specific feature' of intermittent functionality due to high contact resistance, noise and unreliable waveform tracing. The Printed Circuit Board assembly is CLONE. Many third party companies in USA are registered with FDA as a re-packager of medical devices/accessories manufactured overseas, mostly from China. One such example is a company called UNIMED in China. The devices and accessories manufactured by such companies overseas are used by USA based re-packager companies to switch original OEM device or accessory when received for repairs. These repackaging companies pose as third party service provider and manufacturer of medical devices, accessories, cables, SPO2 probes, telemetry and also as suppliers of parts to be used as replacement in place of OEM parts but in fact, most of them are imported from overseas and switched in place of original OEM item received from client. It is very interesting to know what happens to the OEM device or OEM part that is retained by such a third party after replacing with non-OEM part while repairs. Some hospitals report that their OEM items with OEM serial numbers were found on Internet auction sites! 




Epoxy on SMD components, certainly a job of an amateur.  This is an original PCB from GE that is repaired by a third party service company which also drills a hole on the Top plastic case of original GE Corometrics Nautilus Toco transducer 2264 HAX / 2264 LAX to facilitate adjustment of level potentiometer.





If you see a small hole filled with glue on blue colored plastic Top Case of Nautilus Toco transducer then you are sure that your repaired transducer has a PCB fixed using epoxy which is very strange way of repairing any electronic device with SMDs, especially a medical device such as G.E. Corometrics Nautilus Toco 2264 LAX / 2264 HAX




Substandard repair process with silicon pored all over, glued Aluminum nut in the place of Stainless Steel, very hard strain relief which is permanently glued to the bottom case that is also not a GE original part for Corometrics Nautilus Toco 2264 LAX/HAX. 




Substandard repair process with silicon pored all over, Aluminum hardware in place of the Stainless Steel and that too glued after repairs of a original Corometrics Nautilus Toco transducer 2264 LAX/HAX by third party service company. The original flat metal part is rusted heavily as the Non GE Top Plastic case does not match well with their own (third party-non GE) plastic Bottom case even after gluing, the moisture leaks in. 






Non GE plastic bottom case with 20 times harder diaphragm than original GE bottom case for Nautilus Toco transducer 2264 LAX / 2264 HAX.  This hard diaphragm does not allow the repaired 'Nautilus Toco 2264 LAX/HAX transducer to sense the weak to moderate strength contractions.  




Gap between Original GE plastic Bottom Case and Non GE Top Case used by third party service for repair of original GE Nautilus Ultrasound 5700 HAX transducer.



Non GE Ultrasound transducer with 100% non GE parts without any label of model number, serial number, manufacturer's name, FDA approval number or any kind of tractability for compliance - BEING SOLD ON Internet FOR EXTREMELY LOW PRICE. This whole transducer can be sourced from overseas for as low as $ 40 !!!!  Not even SCREWS are compliant with OEM standards to make sure moisture does not get inside.




Original GE Nautilus 5700 LAX/HAX Ultrasound Transducer repaired by a third party - Out of 9 PZT crystals, 2 are non GE PZT crystals that have different sensitivity and large deviation in other parameters. These repaired US transducers certainly cause spurious high fetus heart rate display in the range of 250 BPM on the fetal monitor even when there is no subject or expecting mom being strapped with this repaired transducer.
