Perhaps I should add that the x-ray tubes manufactured at the (long gone) GEC Medical factory at Wembley were made under licence from Machlett (a US company, of course).

These days, the site of what was the GEC Medical factory has become the usual mess (er, development) of warehouses, small industrial units, empty lots, car repair shops and so forth.

The once famous Hirst Research Centre (cavity magnetron, WWII radar etc., etc.) was also located there. Hugo Hirst was one of co-founders (along with Gustav Byng) of the General Electric Company (GEC) in 1889; both were immigrants from Germany.

Lastly (for now, at least) for anyone really interested in current (as in "nowadays" ... as opposed to "Amps") High Voltage techniques, all you need to know (and more) is nicely presented in a download available on the Spellman website (the 2024 High Voltage Reference Manual near bottom right).

For instance, see Section 4 starting page 41 for "Common X-Ray tube failure modes".

I will be raising a yellow card.

Just sent you a private message.

Thanks daisizhou...

@daisizhou never had a lot of sucess taking those kind of things apart and putting them back together again. @ Geoff Hannis E-Health is basically our IT Department .

oh by the way..CMDN stand for Certificate of medical device notification and CMDR certificate of medical device registration.

Hi all, just my two penn'orth here. As the others have said. We have a capital equipping manager at our trust. We have to present any new devices to a management of medical devices group (MDMG). There is usually input from training team and eventually IPC. We also send out a pre-acquisition questionnaire (PAQ) for the company to fill in which does include servicing and spares requirements. Where possible we try and factor tech training into the quote so that we can support any new device

Good morning guys, i hope you are all well. Im after a little help on the above if anyone is using them. We have undergone a trial of the above after having issues getting our old therapy comfort devices repaired. As is usual, we went through the whole trial process and presented them to MDMG and invited our ipc team to come and give input. They didnt, the trial went through okay and them IPC got involved at the eleventh hour and put the chocks on. The cleaning disinfection instructions give mention to MELISEPTOL . We do not use that here so asked if we could use Tristel instead. As expected the manufacturer gave me a tech sheet of the plastics used and advised i speak to Tristel direct. As we all know , this will be a thankless task without outcome. Im reaching out to anyone that has these demand valves with a view to finding out what other trusts are using to disinfect them if not meliseptol. Thanks in advance for any info you can give me.Have a lovely day.

thanks

Sometimes the RT-200 needs to be moved to different rooms for inspection.I often have to go to another room after finishing anything in one room. I am considering whether I need to add a set of lithium batteries to the RT-200.

Is the “Datrend Infutest” you mentioned earlier a manufacturer?


I don't know how the RT-200 interface is connected to the motherboard internally.RS-232 and GPIB may require a signal conversion PCB and then connect to the main board?
This is why I want to obtain pictures of the inside of the RT-200 interface.
The service manual does not explain how the output interface should be connected

About the software?I don't know how the software recorded the data at that time?
Timeter official website also does not provide,So I can only hope that kind people can help me

I disassembled the Fluke INCU™ II Incubator Tester?This host is also malfunctioning.
Hope to share with you

Hi ,

Pls share that service for me too ...

I'll appreciate your help
Pls share to this mail : joswin14.2000@gmail.com

Hi ,

Pls anyone share fujinon XL 4450 endoscopic light source service manual it'll be good for you and also helpful for me.

Pls share to this : joswin14.2000@gmail.com

A long shot, maybe ... but I don't suppose anyone has a copy of that wonderful book in .pdf form?

I've only got a few interesting extracts (pages) in .png.

About "zeroing" and "drift" ... Section F of the March 1988 manual talks about this.

Meanwhile the Troubleshooting Section informs that "excessive drift" shall generate a "HELP 0" display; so if no such message is evident, hopefully we can assume that all is well. There are, however, some pots that may be tweaked if you insist!

Ah ... so hardly "worn out", then; but sadly "out of warranty".

Any other clues?

Assuming that your system(s) can capture and save data to hard-drive (at the central station(s) or wherever), it sounds like XML to PDF software could be the answer.

I spent some time today updating the LCD screen of the T300 and the dust cover of the gasflow channel.
I would like to share it with you.

It looks like the use of antimicrobial coatings in healthcare is set to rise rapidly year on year, WRT medical devices, catheters, implantable, and surgical instruments etc.

As the technology provides anti deterioration maintenance & infection prevention benefits, the coatings in addition are biocompatible, non-toxic, and biostable, which will promote industry development over forecast periods.

The presence of key medical equipment players entering the market, including GE Healthcare Technologies, Johnson & Johnson, Baxter International Inc., and Stryker Corp. is likely to boost the use of antimicrobial maintenance products for medical devices in the future & for retrospective application.

In my opinion, the only advantage of the DPM-1B is that the micro-adjusting pump is integrated into the pressure gauge.The key point is its mechanical fine-tuning pump.It is not excellent for the digital pressure gauge and mechanical potentiometer zero adjustment device on the upper part,Only "mmHg" is displayed,Mechanical potentiometer zero adjustment is not user-friendly and its service life is not expected to be long.
If biomedical engineers only use it for NIBP calibration, DPM-1B is fully sufficient,However, in actual work, in addition to "NIBP" calibration, other medical equipment such as ventilators and anesthesia machines also need calibration and maintenance.And they are usually displayed as "CMH2O or PSI" etc.

What I am most interested in is the mechanical voltage regulation part of DPM-1B.If this part can be separated into a separate mechanical attachment,and use our most readily available syringes,Regardless of any pressure adjustment, it is always used for fine-tuning at the end.Then this enhanced attachment has practical value.

My bad... forgot to ask, what are the models of GE monitors and Central station.

I have an Italian colleague who has worked for many years with GE, Datex et al, if you give me/us more details I'll pass on the query

Hi Carl
Many units such as ours will have technologists employed directly by the Critical care units, and not EBME.
We do all of the above and also manage the stocks of cylinders and do all the training and troubleshooting.

Very Surprised that very few engineers would like to work in London.
