Healthcare Cart

I visited a website which selling compact healthcare cart for medical professionals. I didn't know that there are so many different types of healthcare cart and cabinets selling online. I thought this kind of item would need by hospital or medical professional only. Will they still getting sales from other sources? I don't know about that, but I think sure have others customer else how do they survive with only purchase by hospital? Unless, they supply for whole hospital then the sale should be very high.
