Abstract
Abstract An inexpensive disposable hyperbaric treatment device that can be conveniently applied to any part of the body to treat skin disorders such as ulcers or the like. The device consists of a pliable adhesive backed pad having a central opening formed therein for framing the treatment region and a flaccid bag secured to the top surface of the pad that is adapted to receive a treatment gas under pressure. A collar is provided about the rim of the opening inside the bag so that the pressured gas acts against the pad to insure proper sealing at the opening.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
152 words
Apparatus for administering hyperbaric treatment gas to a region of the skin including a pliable pad having a centrally located opening formed therein for framing the skin treatment region, the pad having an adhesive coating on the outer surface thereof whereby it may be securely attached to the surface of the skin adjacent the treatment region, a pliable annular collar bonded to the inner surface of the pad with the collar completely surrounding the opening formed in said pad, a gastight bag bonded to the outer periphery of said collar to provide a hyperbaric treatment chamber over said opening and also over the collar, and a gas inlet port and a gas outlet port operatively connected to the bag whereby a supply of treatment gas under pressure may be transported into and out of the treatment chamber for providing treatment to the skin and for applying a sealing pressure against the collar.
Claim 2
Dependent Claim
152 words
Apparatus for administering hyperbaric treatment gas to a region of the skin including a pliable pad having a centrally located opening formed therein for framing the skin treatment region, the pad having an adhesive coating on the outer surface thereof whereby it may be securely attached to the surface of the skin adjacent the treatment region, a pliable annular collar bonded to the inner surface of the pad with the collar completely surrounding the opening formed in said pad, a gastight bag bonded to the outer periphery of said collar to provide a hyperbaric treatment chamber over said opening and also over the collar, and a gas inlet port and a gas outlet port operatively connected to the bag whereby a supply of treatment gas under pressure may be transported into and out of the treatment chamber for providing treatment to the skin and for applying a sealing pressure against the collar.
Claim 3
Dependent Claim
27 words
The apparatus of claim 1 in which the bag is formed of a flaccid transparent plastic material whereby the treatment region may be viewed through said bag.
Claim 4
Dependent Claim
25 words
The apparatus of claim 1 wherein the surface area of the collar is equal to about one-fourth of the total surface area of the pad.
Claim 5
Dependent Claim
39 words
The apparatus of claim 1 wherein the bag includes a roof section that is connected to the collar by means of at least one collapsible side panel whereby the roof section may be folded downwardly against the pliable pad.
Claim 6
Dependent Claim
32 words
The apparatus of claim 1 wherein said inlet and outlet ports connected to the bag are male hose connectors that are adaptable to slidably receive treatment gas hoses in gastight relationship therewith.
Claim 7
Dependent Claim
147 words
Apparatus for administering hyperbaric treatment gas to a region of the skin including a pliable pad having a centrally positioned opening therein for framing the skin treatment region and having an adhesive coating on the outer surface thereof whereby the pad can be securely attached to the skin adjacent to the treatment region, an airtight flaccid bag that is secured to the inner surface of said pad about said opening at the predetermined distance from the periphery of the opening so that a collar is formed about the opening inside the bag, means to bring a treatment gas under pressure into said bag to inflate said bag whereby the treatment gas is caused to act downwardly against the collar to form a pressure seal around the opening, and flow regulator means operatively connected to the bag for maintaining the pressure within the bag at a predetermined level.
Claim 8
Dependent Claim
147 words
Apparatus for administering hyperbaric treatment gas to a region of the skin including a pliable pad having a centrally positioned opening therein for framing the skin treatment region and having an adhesive coating on the outer surface thereof whereby the pad can be securely attached to the skin adjacent to the treatment region, an airtight flaccid bag that is secured to the inner surface of said pad about said opening at the predetermined distance from the periphery of the opening so that a collar is formed about the opening inside the bag, means to bring a treatment gas under pressure into said bag to inflate said bag whereby the treatment gas is caused to act downwardly against the collar to form a pressure seal around the opening, and flow regulator means operatively connected to the bag for maintaining the pressure within the bag at a predetermined level.
Claim 9
Dependent Claim
13 words
The apparatus of claim 6 wherein said flow regulator means includes a monometer.
Claim 10
Dependent Claim
23 words
The apparatus of claim 6 wherein the surface area of the collar is about one fourth the total surface area of the pad.
Claim 11
Dependent Claim
27 words
The apparatus of claim 6 wherein the flaccid bag is formed of a transparent plastic material to permit the skin treatment region to be visually observed therethrough.
Claim 12
Dependent Claim
20 words
The apparatus of claim 7 further including a control valve for regulating the amount of gas passing through the system.
Claim 13
Dependent Claim
31 words
The apparatus of claim 6 which further includes a safety valve operatively connected to the regulating means for relieving the pressure within the bag when said pressure exceeds a prescribed limit.
