Hi,
We are developing a battery powered medical device, an ECG, worn on the body. We'd thinking about using a USB connector for data transfer to PC after the record is done. In such a way, we'd need a proper 5kV isolation...
My question is, if the USB connector is cannot be exposed to the patient while worn on his/her body and recording (the other part that is atteched to prevents this, as it covers it) does we need isolation in this case too? The end user only could plug in a USB cable, while the device is detached (although its back leads could be touched)
If not, a docking station would solve the problem as it would cover the back leads too?
Thanks for all the replies, as it is sometimes hard for me to understand the 60601-1 in such questions, as it is a general standard and the device specific standard doesn't say any more concrete things about this.
