Frequently Asked Questions

How does the CastCooler help me with cast itch odor?

The CastCooler relieves cast/splint itch and odor by quickly drying mositre trapped in the lining of your cast/splint. Both cast itch and cast odor result from mositure (perspiration, accidental wetting, etc.) that is trapped in the lining of your cast casusing bacteria to grow. The CastCooler immediately cools and freshens your limb, by completely drying your cast's lining. You will know that the CastCooler is working because there is an immediate cooling sensation as moisture is removed (evaporated) from the lining of your cast.

How does CastCooler® dry my wet saturated cast?

First, use a towel to absorb as much liquid from your cast. Connect the CastCooler® nozzle to your wet-dry vac in normal suction mode and turn on your wet-dry vac. (Note: liquid will damage your household vac so be sure to use a wet/dry type vac.) Wrap the CastCooler® wrap around your cast and the vacuum will cause the CastCooler® to seal against the outside or your cast and begin to pull liquid from the lining through the porus cast and into the wet/dry vac. Immediately, you will feel a cooling air flow. When the cooling sensation subsides, your cast is dry. Note: A saturated, fully wet cast may take some time but the CastCooler® will dry the lining without damaging the cast or lining. The following are guidelines for time needed to dry a completely wet, saturated cast: Short arm 30 minutes, long arm 1+ hours, short leg 2+ hours, full leg 3+ hours.

How does CastCooler® work?

CastCooler creates a gentle vacuum on the outside of your porous cast, drawing fresh air between your skin and the cast. Air flow is directed through the lining of your breathable (fiberglass) orthopedic cast removing moisture and cooling your skin. Without touching your skin, bacteria, itch and odor are significantly reduced. Your cast stays fresh.
