Donjoy Iceman Cold Therapy Repair

This cold therapy machine was the best collateral benefit of Carol’s knee replacement in January of 2024. The new knee, of course, being the actual benefit. At the that time, it cost over $200. Today this device still garnishes a high price tag at $169 and up depending on the accessories supplied. We call it, The Ice Machine.
It’s a cooler that you fill with water and ice. It has a pump that transfers the icy water to a cooling pad that you place over the recovering part of your body and deposits the used water back into the cooler. Instant cold. No need to store pads in your freezer. A trick we learned at the hospital was to place 4 frozen water bottles inside instead of ice cubes. Lasts much longer. We keep 8 bottles of water in the freezer. This way, we have plenty of bottles to use as the others are freezing again and placed into rotation.
A year later, almost to the day, Carol had the other knee replaced. Knowing what to expect this time around, she set up her little corner in the living room with items we knew would make her quality of life recovery a smidge better than last time. A 3-foot tong-like reaching/grabbing bar. A 3-tier shelf on wheels. Small physical therapy equipment/accessories. Crutches. Walker. The Ice Machine.
Just like last year, Carol spent the night in the hospital and was released the following afternoon. Nestled into her recovery corner of the house, I prepared The Ice Machine. Frozen water bottles – check. Fill to the line with water – check. Snap the pad into the water tubing – check. Plug in the power to the pump – no dice. Unplug. Plug back in. Nothing. Fuck me. Guess we are using the old-fashioned ice packs for now.
Turns out the pump died. And a quick internet search provided me with results I did not like. I could not purchase the pump separately. I would have to buy the cooler at a minimum for over $100. The pump unit is sealed. Taking it apart would permanently break it. Plus, it was not a submersible pump. I then turned to other types of pumps – submersibles. Fish aquarium water pumps would fit the bill. I found one on Amazon that offered delivery in the wee hours of the night. Perfect.
The pump arrived on time. I took the old pump out and made some minor adjustments to the piece that brings the tubing and power inside the cooler to accommodate the larger power cord/plug. The tubing was a perfect fit to the pump. My $11 solution worked perfectly. The pump contains a warning: do not use in water over 35ºC. I don’t think that will be an issue.
