Medical equipment testing

Postby lynchelec » Mon Apr 15, 2013 12:57 am

Hi all,
I've been approached by a Hospital to do their PAT testing. I have heard that conventional testers should not be used to test certain medical equipment as some tests could damage them. I know that the code of practice states:
1.2.1 Medical electrical equipment
Sensitive medical equipment, e.g., ECG, infusion pump, ultrasound machines, X-ray equipment etc., should only be inspected and tested by a competent person, with suitable experience, familiar with BS EN 62353. Equipment covered by and requiring inspection and testing in accordance with BS EN 62353 is outside the scope of this Code of Practice.

I am aware that there are medical equipment electrical safety testers on the market that obviously comply with BS EN 62353. So am I right in assuming that medical equipment is exempt from PAT testing and that organisations in charge of such medical equipment should ensure that it be routinely tested with a specialists testers? Any info on this would be appreciated!

I dont understand. Surely "medical equipment" with an earth should just be tested just like IT equipment ??

Well... no.
Didn't you read the extract from the CoP that lynchelec posted above?
It's the reason Seaward have a whole division, Rigel Medical, dedicated to 'Biomedical Test Equipment': http://www.rigelmedical.com/products/electrical-safety

To all,
Rigel Medical offer support and training in testing of medical devices to EN BS 62353 and 60601. Medical devices are tested under conditions that require dedicated test equipment as well as measuring leakage down below 50uA (typical 10-20uA). These levels are achievable with products such as the Rigel safety analysers:

http://www.rigelmedical.com/products/electrical-safety

What's equally important is that those who conduct testing, have an understanding of how the medical equipment actually functions and connects to the patient. (ie what are the functions and class of applied parts and patient connections). These will determine what test limits to apply and how to connect to the safety analyser.

If you have any particular requirements or would like more information, please email support@rigelmedical.com

many thanks
John Backes
