Ray, Your question is interesting to me not because I want to do the same or a similar thing, but it high-lights a small point that has always 'niggled' me. That of the reference made firstly to us as Biomedical technicians and secondly to your query for an appropriate definition for equipment under our jurisdiction. The first point I will not elaborate over, suffice it to say that I have never agreed with our title of Bio-medical engineers as we are not in the field of Biomedical work i.e. working with R & D of the life-sciences etc. The main thrust in our work area is that of the management and maintenance (repairing) of electrical medical equipment and that is all. 'Nuff said!
With reference to an appropriate definition for the large remit and gammit of equipment we look after, well what has always to me felt right ever since I can remember starting in the field is purely and simply Electro-Medical Equipment(or Devices). I have seen written Electrical Medical and Medical Electrical but not electro-biomedical. These just do not 'ring' well with me, feeling rather cumbersome in comparison. I appreciate that the above does not cover your request for a definition. As John says,it seems to cover well the main areas.
