Abstract
Abstract A cast drying system is disclosed for drying a cast. The cast drying system includes a cast drying device including an inflatable bladder made of a flexible material, the bladder having an outer wall and an inner wall jointed together to define an enclosed expansion chamber. The inflatable bladder further includes first air passage means for permitting air to pass into the inflatable bladder which communicates with the expansion chamber. The inner wall preferably includes second air passage means for permitting air to pass out of the expansion chamber such that air originating from the source of forced air can be directed against a cast when the cast is engaged with the inner wall of the inflatable bladder. The system further includes coupling means for conveying forced air originating from the source of forced air into the expansion chamber. The process for drying a cast is also disclosed. The process includes the steps of engaging the cast with the inflatable bladder and interconnecting the drying device with the source of forced air such that air originating from the source of forced air passes through the bladder and into the cast to dry the cast.
