Abstract
A hyperbaric oxygen device and methods of applying hyperbaric oxygen are disclosed. The device comprises an enclosure including a collapsible bag defined by two sheets of fluid impervious material sealed together at both ends such that gas can be delivered between the sheets to inflate the enclosure to a rigid state and maintain the enclosure in the rigid state when oxygen pressure in the interior of the enclosure is cycled between ambient pressure and above ambient pressure.
Claims28
A topical hyperbaric device for delivering oxygen to an extremity of a patient comprising:
- an enclosure including an interior and an exterior, the enclosure closed on one end and open on the other end and sized and shaped to receive the patient's extremity, the enclosure defined by collapsible bag including two sheets of fluid impervious material sealed together at both ends, a first side of one sheet defining the exterior of the enclosure, a first side of the other sheet defining the interior of the enclosure such that gas can be delivered between the sheets to inflate and maintain the enclosure in a substantially rigid condition when oxygen pressure in the interior of the enclosure is cycled between first and second pressures.
A topical hyperbaric device comprising:
- a main chamber defined by a collapsible bag comprising a sheet of fluid impervious material, the bag being sealed on a first end and open on a second end, the main chamber sized and shaped to enclose a patient's extremity;
- an inflatable cuff proximate the open end of the chamber for sealing the main chamber around the patient's extremity;
- and
- means for retaining the collapsible bag in a rigid state when gas is cycled between first and second pressures such that the interior of the main chamber does not contact the patient's extremity.
A method of treating an extremity of a patient with hyperbaric oxygen comprising:
- placing a collapsible bag having an open end and a closed end in a substantially rigid state defining a chamber adapted to receive a patients extremity;
- inserting a patient's extremity through the open end of the chamber;
- sealing the chamber around the patient's extremity to prevent gas delivered to the interior of the chamber from escaping;
- and
- delivering oxygen to the interior of the chamber in a pulsed manner between first and second pressures, wherein the bag remains in a substantially rigid state and does not collapse around the patient's extremity.
