Salient characteristics:
The anti-shock pneumatic trousers shall consist of the outer garment with three individual, removable air chambers, three manually adjustable inflation deflation valves, three relief valves, a foot operated air pump, inflation tubing with air distribution connector, operating instructions and a carrying case.
The outer garment shall be constructed of a flexible, washable, non-shrinking, fabric material with hook and pile closures to secure the garment around the patient.
The outer garment shall have provisions for three separate, removable air chambers, one for each leg and one for the abdomen. The air chambers shall be constructed of a heat sealable material that is impervious to gases, and capable of maintaining an air pressure between 88 and 120 mm Hg, when installed in the outer garment with the hook and pile fasteners closed in the normal manner of use. Each air chamber shall be individually controlled and shall be removable from the outer garment to facilitate necessary repairs and or replacement.
The air input to each air chamber shall be controlled through a manually adjustable inflation/deflation valve, and a normally closed pressure relief valve set to automatically release pressure within the range of 104 mm Hg ± 15% and shall automatically return to the closed position at pressure not less than 80 mm Hg.
The foot operated pump shall consist of a closed come shaped cavity, and be equipped with either integral or adjacent inlet and outlet valves. The air inlet valve shall be provided with a check valve to prevent air from being expelled through the inlet valve during the pump pressure stroke. The air output valve shall be provided with a check valve to prevent air from the pressurized garment from re-entering the pump.
The output of the foot operated air pump shall be distributed to the three air chamber input valves through appropriate use of X-type or Y-type connectors and suitable inflation tubing.
The carrying case shall be constructed of commercial grade high impact plastic, high density polyethylene, or durable nylon fabric material. The pneumatic trousers and all accessories shall fit in the closed carrying case. The carrying case shall be provided with a carrying handle and latching device.
