That looks like a pressure infuser bag. You place a bag of fluids inside of it and inflate. It's for rapidly infusing a fluid into someone who may, for example, require fluids to treat a rapidly dropping blood pressure.

It looks like there is no fluid bag inside of it though.

And sepsis can happen from pneumonia which can cause a drop in blood pressure.

Love y'all. Prayers n' light.
