Controller for an extremity hyperbaric device
First Claim
1. A hyperbaric wound treatment device comprising:
- a chamber having an interior and an open end in communication therewith; and
an inflatable tubular limb sleeve configured for sealing against the limb of a patient including an inner wall spaced apart from an outer wall forming an interior region therebetween for receiving an inflation gas, the inner wall and the outer wall coupled to the open end of the chamber and extending away therefrom, the inner wall and the outer wall of the sleeve configured to be positioned between a first orientation and a second orientation, wherein the first orientation comprises the inner wall and the outer wall of the sleeve extending from the open end of the chamber wholly outwardly of the interior of the chamber, wherein the second orientation comprises the inner wall and the outer wall of the sleeve extending from the open end of the chamber wholly within the interior of the chamber, and wherein the inner wall and the outer wall of the sleeve is positionable between the first and second orientations at least partially within the interior of the chamber and partially outside the interior of the chamber adjacent the open end of the chamber.

Abstract
A controller is operable to selectively supply gas to, and evacuate gas from, regions of a hyperbaric wound treatment chamber. The controller operates to inflate a passage or rib of the device to provide that the device is made sufficiently rigid for inserting a limb therethrough, and inflate an inflatable cuff to create a seal against the limb. The controller also operates to evacuate ambient air trapped within the chamber, and optionally partially evacuate the passage or rib, after the seal is created by the inflatable cuff, and then introduce oxygen into the chamber, and optionally inflate the passage or rib. The cuff, when inflated and creating a seal against a limb, optionally is at least partially within the chamber, and the treatment gas is supplied to the chamber to maintain the seal of the cuff against the limb.
