Abstract
An air sleeve for stimulating blood flow and providing aeration around, under and within a cast includes a base film with an array of nodal air cells, at least some of which are perforated on a skin side of the base film. A spacer fabric layer, which is at least partially air permeable, is disposed on the skin side of the base film, and a valve is extendable through the cast and is in fluid communication with the air cells.

An air sleeve for stimulating blood flow and providing aeration around, under and within a cast, the air sleeve comprising:
- a base film including an array of nodal air cells, at least some of the air cells being perforated on a skin side of the base film;
- a spacer fabric layer disposed on the skin side of the base film, the spacer fabric being at least partially air permeable;
- and
- a valve extendable through the cast and in fluid communication with the air cells.
An air sleeve for stimulating blood flow and providing aeration around, under and within a cast, the air sleeve comprising:
- facing sheets of film that are RF welded together to define an array of nodal air cells connected via integrated plumbing channels, at least some of the air cells being perforated on a skin side of the facing sheets;
- and
- a plumbing fitting extendable through the cast and in fluid communication with the air cells via the integrated plumbing channels.
A method for stimulating blood flow and providing aeration around, under and within a cast using an air sleeve including a base film with an array of nodal air cells, at least some of which are perforated on a skin side of the base film, a spacer fabric layer that is at least partially air permeable disposed on the skin side of the base film, and a valve extendable through the cast and in fluid communication with the air cells, the method comprising:
- (a) connecting a pump to the valve;
- (b) inflating the air cells;
- and
- (c) bleeding air through the perforations and the spacer fabric layer to aerate a wearer's skin inside the case.
