I had a knee replacement and was given this unit. Because my knee was numb I guess I couldn’t feel the pressure when it inflated and it put too much pressure on my incision site causing some serious bleeding. I have no clue why this would be prescribed to a person who has an incision site. Be careful if you are using this. It will blow up and put lots of pressure on your wound.
FWIW... Our Cyro/Cuff began leaking at the tube connection to the cuff. The small o-ring on the fitting that inserts into the Cuff fitting had split. I found the DANCO 96723 #6 o-ring, 7/16” O.D. X 5/16” I.D. X1/16” to be a good fit replacement. Got it at Home Despot.
The device really helps back pain. However, it would be most helpful, if you provided better information. How to empty the cuff. Best placement for optimum relief, how many parts are there & how do they connect & where to order extra/missing parts for example.
