A compression system for applying gradient sequential compression of a patient's limb and accelerating deep venous blood flow in the limb from a source of pressurized fluid is provided. The system includes a means for supplying a source of pressurized fluid, said source having a connector interface comprising at least one outlet port, a connector for providing a continuous fluid passageway between the source of pressurized fluid and a compression sleeve. The compression sleeve includes a pair of dimensionally stable, flexible sheets of fluid impervious material, said sheets comprising a thermoplastic film and a fabric applied together into a unitary sheet and means for securing the thermoplastic films of said sheets together along lines defining at least one inflatable chamber disposed longitudinally along the sleeve. A fitting is secured to one of the thermoplastic films of each chamber and in fluid communication with a source of pressurized fluid for inflating the chamber. There is also provided a means for releasably securing the sleeve around the limb of a patient with the chamber encircling the limb.

Compression sleeve for use with a gradient sequential compression system

A fluid connector for a compression system for improving venous blood flow in a patient provides a continuous fluid passageway between a source of pressurized fluid and a plurality of inflatable chambers in an elongated pressure sleeve. The connector includes a flexible conduit comprising a plurality of elongate hollow tubes having a corresponding plurality of fittings attached at one end of the conduit. The fittings form a fluid-tight seal between the conduit and a corresponding plurality of outlet ports communicating with the source of pressurized fluid. A grip portion is provided adjacent the end of the conduit. The grip portion is releasably attached to the source of pressurized fluid and grips the conduit securely between adjacent tubes such that the fittings move freely and independently relative to the grip portion. In this manner, leakage of the pressurized fluid and contamination of the fluid stream is minimized, while stresses induced in the conduit are not transferred to the fittings. At its other end, the conduit may include couplers for forming a fluid-tight seal with sleeve fittings attached to the inflatable chambers of the pressure sleeve.

The disclosure relates to a pneumatic splint formed of three similarly shaped walls of flexible thermoplastic material. The inner and outer walls are of identical shape and are peripherally bonded to each other. The intermediate wall is of lesser peripheral dimension and has three of its edges bonded to corresponding edges of the inner and outer walls and the fourth edge bonded to an intermediate portion of the outer wall. The intermediate wall is provided with a plurality of spaced apertures and a plurality of equally spaced welded bonds to the outer wall. The application of fluid pressure to the interior of the splint when rolled into an annular configuration to loosely surround a human limb will expand the inner wall into intermittent engagement with the limb and the outer wall into a uniform, quilted cushion configuration.

An anti-shock pressure garment having a trouser portion and an upper portion connected thereto forming a one-piece construction. The upper portion has a flexible back panel which is not inflatable and a front panel containing a plurality of pressure chambers or bladders which wherein inflated inpose pressure on the thorax and abdomen of the patient. The legs of the trousers have pressure chambers or bladders which when wrapped about the patient's legs, can impose the desired pressure. The upper portion is length adjustable to allow the garment to cover a greater size range of patients. This is accomplished by folding down the upper portion of the front and rear panels and securing them in folded position.

Anti-shock pressure garment

A portable apparatus for controllably cooling and variably, intermittently applying pressure to a portion of a body part of a mammalian organism comprising a liquid supply and control unit having means to store, circulate, cool, agitate, and pressurize a fluid and means to communicate via fluid communication means to a hydraulic appliance having a unitary body, with an unrestricted inlet port to receive the fluid, and an outlet port in association with a fluid flow retardation means secured to the interior surface of the outlet port. The reservoir in the supply unit is arranged with a heat exchanger immersed in the liquid and agitating means to avoid thermal stratification of the liquid. The reservoir is mounted in the supply unit with sufficient support to sustain the weight of a human and has an open top of sufficient dimensions to receive a human limb whereby the reservoir can be employed as a whirlpool bath. A cover is provided for the open top when the reservoir is not used as a whirlpool bath.
