Cast ventilation system
First Claim
1. A ventilation system for a cast of the type which encompasses a limb with a rigid material such that an inside surface of the cast faces the limb while an outside surface of the cast is spaced outwardly from the inside surface, said ventilation system comprising:
- a tube insertable through said cast so that one end of said tube is open to the limb while the other end of the tube is open to the outside surface of the cast,a source of pressurized air,means for connecting said source of pressurized air to said other end of said tube,a plurality of flange sections which extend outwardly from said one end of said tube, sad tube including a longitudinally extending slot open to said one end of said tube between each adjacent pair of flange sections, wherein said tube is constructed of a resilient material so that, upon compression of said flange sections together, said flange sections are insertable through an opening in the cast and so that, after passage through the cast opening, said flange members expand outwardly and engage the inner surface of the cast and a nut which threadably engages said tube so that the cast is sandwiched in between said flange sections and said nut.

Abstract
A ventilation system is disclosed for a cast of the type which encompasses a limb with a rigid material such that an inside surface of the cast faces the limb while an outside surface of the cast is spaced outwardly from the inside surface. The ventilation system includes a tube insertable through the cast so that one end of the tube is open to the limb while the other end of the tube is open to the outside surface of the cast. A source of pressurized air is then fluidly connected to the other or outside end of the tube thus forcing air flow through the tube and into the area between the inside surface of the cast and the limb.
