Pressure manual-regulating anti-pressure-sore seat cushion

Abstract

The invention relates to a pressure manual-regulating anti-pressure-sore seat cushion, which comprises an airbag array consisting of a plurality of airbags, a plurality of air passages, a substrate, a plurality of air ducts and a manual inflation device, wherein the airbag array is divided into at least four airbag areas; the airbags in each airbag area are communicated, but are not communicated with those in any other adjacent airbag area; the air passages are positioned below the airbag array; each air passage is connected and communicated with at least one of the airbag areas; the airbag array consisting of the airbags and the air passages are arranged on the substrate; the air ducts are arranged in the substrate; one end of each air duct is communicated with the corresponding air passage, and the other end of each air duct extends out of the seat cushion; a joint is arranged at the end, extending out of the seat cushion, of each air duct; a respective valve is arranged on each air duct; the manual inflation device is communicated with the joints of the air ducts through fluid to inflate the airbags.

Description

technical field [0001] The invention relates to a cushion, in particular to a manually adjustable pressure sore cushion for people who need to maintain a sitting posture for a long time due to illness or injury. Background technique [0002] Pressure sores refer to the long-term pressure on local tissues of the body or the stimulation of long-term physical and chemical factors, which cause neurotrophic disorders and blood circulation disorders. The local tissues continue to be ischemic, hypoxic, and malnourished, resulting in the loss of normal skin functions. Lead to soft tissue ulceration and necrosis. For example, local tissue is subject to continuous vertical pressure, which can also be caused by friction and shear force, usually caused by the combined action of 2 to 3 forces. [0003] Pressure sore is a common clinical complication, not the primary disease. Most of it is the damage caused by other primary diseases without good care. Once a pressure sore occurs, it wil...

AI Technical Summary

Problems solved by technology

[0007] When the cushions of the above two patents are applied to people who maintain a sitting posture for a long time, although they can bring a very comfortable sitting posture and feeling, these two cushions will still exert pressure on the human body continuously, so there will still be high pressure induced. chance of sores
