Abstract
An improved cold/hot pack for physiotherapy having a completely sealed flexible pouch (16). The cavity of the pouch is filled with a plurality of approximately pea sized or larger hollow capsules (20). The cavities of the hollow capsules are filled with cold/hot storing fluid or gel (22). Partitions prevent migration of the capsules within the pouch and a screened plug permits air to be expelled from the pouch while the capsules are retained.
Claims3
A method of providing heat or cold therapy to a selected body part of a patient comprising:
- (a) providing a therapeutic pack at a desired temperature, said pack comprising:
- (i) a pouch readily deformable over a therapeutic range of temperatures,
- (ii) a plurality of hollow capsules disposed within said pouch, said capsules encapsulating means stable over a therapeutic range of temperatures for retarding temperature change of said capsules once said capsules are at a desired temperature,
- (iii) plug means for controlled movement of air into and out of said pouch;
- (b) positioning said pack in conformable relation over a contour of the body part;
- (c) removing air from said pack through said plug means to immobilize said pack in its contact configuration with the body part.
A deformable therapeutic pack for delivering heat or cold to a selected body part of a human or animal, said deformable pack capable of immobilized conformity with a contour of the body part, said pack comprising:
- (a) a pouch readily deformable over a therapeutic range of temperatures, said pouch provided with means for partitioning said pouch into at least two contiguous chambers to prevent uncontrolled migration of said capsules within said pouch;
- (b) a plurality of capsules disposed within each of the chambers of said pouch, said capsules encapsulating means for retarding temperature change of said capsules from a desired capsule temperature;
- (c) plug means for controlled movement of air into and out of said pouch, said plug means comprising a tube coupled to an opening in said pouch and fitted with a screen to retain said capsules within said pouch but through which air may freely pass.
