Medical Equipment Testing????

[Dman1987]

Hi

I was at a hospital testing and the blood pressure machine only has a AC adapter and iec lead , so why cant you just use a seaward 500 to pat test , why do you need to be medical pat machine?

also same for Bed unit , you can get a class 1 test off it , and some are class 2 but both can be tested on a Seaward 500.

Have a read of this.

That is an interesting read.

I was aware that you can get medial-grade PSU and RFI filters with very low leakage current (no class-Y capacitors from live to earth for a start!), but I must say I never thought about medical PAT testing before, mostly as it is not something I have ever had any dealings with.

That 'Rigel Medical SafeTest 60 PAT Tester' mentioned above is pricey at (about £1.4k inc VAT), but not ridiculous by MFT standards or the like. I guess if you are going to offer that service you simply have to have the appropriate kit and charge accordingly.

Well worth publicising the differences though, as some clients might not be aware that 'PAT testing' comes in different levels of specialisation and for some cases you simply can't go for the cheapest generic service offer.

By coincidence, I've just been asked to PAT test some equipment at the "cat clinic" for a charity that I'm involved with.

I only occasionally do PAT testing (have a Seaward 100), and most of the stuff is simple leads or appliances, but there is some potentially 'medical' or 'lab' equipment in there.

From the link, it appears that medical devices also require some sort of test that simulates a person,

• Patient Leakage
• Patient Auxiliary leakage
• Patient Type F Leakage

(patient leakage sounds like a bad thing normally!)

But I doubt the medical pat testers have different "body models" for cats, dogs etc.

I don't currently have an up to date Code of Practise and no point buying one since a new issue is imminent, which apparently has significant changes in it.

Anyone with the current CoP willing to see if it says anything specifically about vetinary equipment and required tests outside what a Seaward 100 or MFT can do, or how much the actual text differs from the no doubt marketing led stuff from Seaward?

Or an even longer shot, anyone not too far from Palmers Green with the right kit who would be willing to do a small charity a favour with the couple of items affected?

Have a look at Westward's post ! I can tell you that in the 4th edition COP It states that Equipment covered by and requiring inspection and testing in accordance with BS EN 62353 is outside the scope of this Code of practice

Hi. If it helps, Medical Devices (correct legal term) have IEC 62353 guidance in place for testing. IEC 60601 is the build standard by which they are regulated. There are dedcated medial device testers -

Acceptance Testing of Medical Equipment

Acceptance Testing of Medical Equipment. - The processes that will check that equipment meets safety standards, meets clinical requirements, and the procurement requirements of the Hospital from the day it arrives.

On a different point to this thread - you also need to be aware that any area that uses medical devices with applied parts means the area or room needs to comply with the BS7671 special locations section known as Medical Locations. I offer training on Medical Locations - hence mentioning it

Sorry - forgot to mention that using a medical device on an animal does not have to be tested as per the tests required for humans. However, the wiring in a vets or cosmetic place has to be wired as a medical location - see GN7. My training course takes some time to cover all of the unique requirements and processes for a medial location mainly as GN7 isn't written very well. With respect to micro shock that can occur with humans, the human body model simply is a 1k resistor with a HF block filter. This is because the human heart can stop with small 50Hz currents passing though it. Realise the horse has bolted (or cats) for this thread but 62353 is not meant for devices used on animals. The main difference is because only pigs have a similar heart to humans with coronary arteries etc - this is a basic reason.
