3 Sheets-Sheet 3 EMERGENCY IN FLATABLE RECOMPRESSION UNIT STATEMENT OF GOVERNMENT INTEREST v The invention described herein may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment of any royalties thereon or therefor.

BACKGROUND OF THE INVENTION In locations where much diving activity is in progress, it is usual to provide a -recompression chamber with medical facilities and all other appurtenances necessary for the care of divers. These standard chambers are heavy and cumbersome as well as expensive, and many diving activities have too little diving to support their use. However, when a diver is incapacitated by a diving disease such as bends, air embolism, or spontaneous pneumothorax, it is necessary for him to have prompt treatment. In such cases it may be difficult, if not impossible, to provide such treatment early enough to secure the best results therefrom. Also, routine diving involves controlled decompression at times.

The present invention provides an improved recompression chamber suitable for the accommodations of one diver and having the essential elements necessary for minimum temporary care. The present invention is portable by virtue of its small size and collapsibility. While portable recompression chambers are available such as that shown in U. S. Pat. No. 2,448,546 to Plemel et al. dated 7 Sept. 1948, none are flexible and collapsible and therefore as portable as the present invention. Also, none of the available portable recompression chambers provide elongated entrance means for easy entrance into and out of the chamber.

SUMMARY OF THE INVENTION not available on the diving site. The period of time in transportation can be quite expensive, painful and dangerous for the stricken diver. The present invention is a high-strength pressure-proof rubber-coated device for transporting the victim under a desirable environmental pressure to a permanent recompression station and medical aid.

Due to the flexible and collapsible nature of the present invention, it possesses advantages over presently available recompression chambers in portability, size, weight and cost. Also, due to the extended length of the self-sealing entrance to the chamber, stricken divers may enter and exit the chamber with much greater ease than is true with prior art portable recompression chambers.

FIG. 2 shows the invention in its deflated state;

,FIG. 3 shows the invention with only the air mattress inflated;

FIG. 5 is cross section V V of FIG. 1.

DESCRIPTION OF THE PREFERRED EMBODIMENT The emergency inflatable recompression unit 10 is a flexible container constructed of a high-strength pressure-proof rubber-coated fabric. The unit 10 comprises two separately inflatable compartments. The larger of the two compartments is a recompression chamber 12 approximately 28-inches in diameter by -inches long. The smaller compartment is an air mattress 14 in the shape of an ovoid rubber raft which supports the recompression chamber. Attached to the air mattress 14 are handles 15 which are employed for manually lifting the air mattress and decompression chamber. The chamber 12 is attached to the air mattress 14 by any conventional manner such as by straps 17.

A pressurizing system used for inflating both compartments comprises a scuba tank 16 or any other well known air source connected to a high pressure gauge 20, a regulator 22, a low pressure gauge 24, a hand valve 26, a flexible hose 18 and a self-sealing quick disconnect coupling 28 respectively, all connected in series. A self-sealing quick disconnect nipple 30 is located in air mattress 14 and two self-sealing quick disconnect nipples 30 are located in manifold 32 of recompression chamber 12. One of the quick disconnect nipples 30 of the manifold 32 may be connected to the pressurization system, while the other is connected to a commercially available vent valve while provides air circulation. On each end of recompression chamber 12 is a plexiglass viewing port 34 for allowing observance of a person inside the recompression chamber.

The interior of recompression chamber 12 is made accessible through an opening at the top of the chamber. The opening is closable with a self-sealing pressure-proof zipper 36. Referring to FIG. 4, the chamber is sealed closed by sealing lips 38 after zipper 40 has been closed. The lateral stress on the zipper is reduced by inserting a metal rod 42 through a series of load loops 44 which pass over the top of the zipper.

Along the bottom of the interior of chamber 12 is a nylon mesh support 46 approximately attached to the sides of the chamber. When the chamber is inflated, the mesh support 46 is stretched to serve as a cushion for the stricken diver.

OPERATION Upon discovering a diver with symptoms of one of the diving diseases, the emergency inflatable recompression unit 10 is removed from a carrying case and folded out on a level surface. The pressurizing system is then attached to one or more scuba tanks. The quick disconnect coupling 28 is then mated to the quick sure regulator is returned to zero pressure, the hand valve is closed and the quick disconnect coupling 28 is attached to a quick disconnect nipple 30 on manifold 32 of the recompression chamber. The pressure regulator is then set for 2 psi and the hand valve is opened. The stricken diver enters the recompression chamber, and the self-sealing zipper is closed. The relief valve is mounted on the manifold and set to the desired pressure for recompressing the stricken diver. The pressure regulator is then adjusted to provide the pressure needed to inflate the recompression chamber and to relieve the diver of discomfort. The unit is then transported with the diver into a permanent recompression chamber.

What is claimed is:

1. An emergency inflatable recompression unit comprising:

a flexible, collapsible recompression chamber;

a scalable opening in said chamber for allowing ingress and egress to said chamber; an integral ovoid shaped inflatable air mattress attached to the exterior bottom of said chamber;
