Abstract: An apparatus for generating air pressure pulses delivered to a vest or mattress accommodating a person. A diaphragm located within the housing is connected to a wave generator and amplifier operable to vibrate the diaphragm. The vibrating diaphragm produces air pressure pulses which are delivered to the air accommodating receiver to subject the person to repetitive force pulses.

Abstract: A pressure sock for the ambulatory treatment of venous ulcers about the ankle and lower portion of the leg of a patient. The sock has a lamina provided with a network of spaced apart, interconnected chambers which can be inflated by the introduction of fluid to exert pressure on the foot and lower leg. The sock has and an inner lining of a relatively soft, non-allergenic material and a non-distensible outer jacket.

Abstract: After body surgery a patient has at her or his command the ability to create a suitable binding pressure in the locale of her or his body wound. An inflatable cushion, also referred to as an air bladder, is located over and beyond the wound. This positioning of the inflatable cushion is maintained by a strong netting which surrounds the body portion, and passes directly on and over the inflatable cushion. This surrounding netting is comfortably sized by the adjustment of selected spaced fasteners. The air pressure may be increased by the patient, or a person aiding the patient, by hand squeezing sequences of a hand gripping air bulb pump.

Abstract: A method and apparatus for enhancing venous circulation in persons having venous insufficiencies and/or for effecting muscular massage for preventing muscle atrophy. This is attained by a wrap or sleeve adapted to circumscribe the portion of the body to be treated which includes an inflatable flexible tubing or tube which is inflated and deflated for producing a smooth, progressive massaging force on the body portion being treated. In operation, a fluid pressure inflates the respective tubes in a progressive manner whereby a massaging force is progressively applied against the body part as the tubes are sequentially inflated and which massaging force is relieved when the tubes are deflated. A control circuit is provided to control the inflation and deflation of the flexible tubing to effect a repetitive cycle in a predetermined time sequence.

Abstract: A system for pneumatically controlling the blood circulation in the lower body extremities in enhancing effectiveness of cardiopulmonary resuscitation on a subject is described which comprises an inflatable garment for covering a preselected portion of the lower body and legs of a subject, a source of pressurized air operatively connected to the garment through a control valve configured for controllably deflating and inflating the garment in response to the application and removal of cardiopulmonary resuscitation pressure applied to a sensor disposed on the chest of a subject.

Abstract: A medical appliance is disclosed employing multiple inflatable components which cooperate to apply compressive pressure to each leg of a person. The appliance includes physically separate upper and lower leg components each having individual chambers joined together with flexible straps for attachment to the wearer. The appliance can further include a physically separate inflatable bladder elements for attachment to the wearer's pelvic region.

Abstract: An adapter is disclosed for converting devices for applying compressive pressure to the legs by means of a compression sleeve around the leg wherein compressed air is delivered to the sleeve through multiple conduits to like devices wherein a single conduit is utilized to supply compressed air to the sleeve.
