Joerg,
The design suggested was a cheap and fast replacement only for the digitalpart ( conversion and transmission for computer )
The rest would be taken of the INPUT part from the already discussed circuit ( with the legal use requirements ) .
For now , let's put it on the side and try following Jiva's idea of keepthe focus in one machine's to not slow the group ( althougt
I think it is really going fast , because less than 6 months to have a PCBdone is a very good time ! ).

Waldemar
Your design should work, however:
Where is the galvanic isolation according to IEC601-1 that separates
the PC from the patient ?
Regards,

Joerg
