The correct place for making requests like these is in Renderosity's "Marketplace Wishing Well" forum thread. https://www.renderosity.com/mod/forumpro/?forum_id=1244

Apologies, I should have mentioned this before engaging in the attempt to fulfill 'wolfmanjim's' request.

generation2235, you'll have much better luck if you repeat this request in that forum. It will just get lost here.

...... I believe there is little here that meets your "wish list." The best place I know to get inexpensive models of your first three items is at "CGTrader.com" Use "hospital" in your search terms. There are at least three versions of your first three items in three packages, all at a good price. I've used all of these myself for earlier work with a client in the medical profession. They are good models.

You'll want these in *.obj file format if you are going to use them in Poser. Then, follow up with a Renderosity "Marketplace Wish Well" request for the Poser poseable cuff and portable blood pressure checker, etc. These should be no great problem for a model-builder and you'll probably get what you need in short order. (I would help you if I could, but I know nothing of Poser - am just a simple Maya model-builder.)
