## Abstract

A portable and rechargeable cast ventilating system adapted for use on casts, the system comprises of a portable fluid flow manipulations device, a manifold collar, and at least one tube. The system is attached to a cast being worn by a user so that each tube is inserted between the cast and the body part of the user being covered by the cast, the manipulation collar is attached to the cast so that the collar operatively connects to the tubes, and the portable fluid flow manipulation device operatively connects to the collar. The system delivers a fluid flow within a cast being worn by the user. The temperature of the fluid flow delivered to areas being covered by the cast might be controlled by a heat transfer element of the fluid flow manipulation device.

## Background
BACKGROUND
The present invention is directed to the field of portable cast ventilating systems adapted for use on casts.
The inventor of the present invention conceived the invention when she suffered a fracture. They treated the fracture by placing a cast over the fracture. She noticed that the cast became increasingly uncomfortable as time passed. The reason that the cast was uncomfortable stemmed from the fact that there was no fluid circulation between the cast and her skin.
Because of the lack of fluid circulation, her body sweated in the areas immediately covered by the cast. The sweating caused her to itch and she devised ways of jabbing things within the cast to somewhat create a fluid flow within the cast and also to scratch the areas not being in contact with a fluid flow.
Another problem she encountered when she used the cast was bacteria build up caused by the lack of fluid circulation that in turn generated an odor.
Stand alone ventilators for casts have been disclosed in U.S. Pat. Nos. 6,120,469; 4,898,160; 4,387,710; 3,998,220; 4,308,862; 7,022,093; 6,416,534 B1; AND 4,677,970. None of the recited patents disclose a portable cast ventilating system having a rechargeable power source and a rechargeable heat transfer element.
For the foregoing reasons, there is a need for a portable cast ventilating system that is portable, that has a rechargeable power source, and that has a rechargeable heating element that is adapted for the use on casts.
