If you have a prescription for one, insurance may pay for it. Usually it’s for a temporary rental unit. I found mine ( by Flowtron) on EBay for under $100. There is one on EBay now for $49, but it’s incomplete. It doesn’t have the air tubes or leg garments. There are other manufacturers, Devon, Circulaflow, but Flowtron is the one used by most hospitals. After rental, many companies sell them used. Hope that helps.
