Lower limb tool for preventing pressure sores through water circulation pressure reduction

Abstract

The invention relates to the technical field of medical instruments, in particular to a lower limb tool for preventing pressure sores through water circulation pressure reduction. The lower limb toolfor preventing the pressure sores through water circulation pressure reduction comprises a pressure reduction water bag, a shell for containing the pressure reduction water bag and an external circulation water tank for controlling water circulation in the pressure reduction water bag, a water pump is arranged in the external circulation water tank, and the pressure reduction water bag comprises adownwards-sunken foot supporting part and a leg supporting part; a water bag water inlet and a water bag water outlet are formed in the end, away from the foot supporting part, of the leg supportingpart in the length direction of the pressure reduction water bag, a water tank water inlet nozzle and a water tank water outlet nozzle are arranged on the external circulation water tank, and the water bag water outlet is connected with the water tank water inlet nozzle through a first guide pipe; and the water bag water inlet is connected with the water tank water outlet nozzle through a second guide pipe. According to the lower limb tool, the pressure sores can be prevented, the care time of nursing personnel can be greatly reduced, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a lower extremity device for preventing pressure sores by using water circulation to reduce pressure. Background technique [0002] Pressure sores, also known as decubitus ulcers or pressure ulcers, are caused by long-term pressure on the local skin of the body, affecting blood circulation, resulting in damage, ulcers and even necrosis of the skin and subcutaneous tissue due to nutritional deficiencies. Occurs in the protruding parts of the bones under pressure, such as the sacrum, ankle, heel, buttocks, etc. Pressure sores are not a primary disease in themselves, but are mostly caused by poor care of bedridden patients. Pressure sores will bring a series of hazards, increasing the suffering of patients, aggravating the underlying condition, prolonging the course of the disease, and even causing sepsis and life-threatening. At present, the commonly used clinical method ...
