Pressure-sore-preventing cushion capable of automatically regulating pressure

Abstract

The invention relates to a pressure-sore-preventing cushion capable of automatically regulating the pressure. The pressure-sore-preventing cushion comprises an airbag array composed of a plurality of airbags, a plurality of air channels, a base, a plurality of air guide pipes and an automatic pressure adjusting device, wherein the airbag array is divided into four airbag regions; all the airbags in each airbag region are communicated with one another; the airbags of any two adjacent airbag regions are not communicated; the plurality of air channels are located below the airbag array; each air channel is connected with at least one of the airbag regions and is communicated with the airbag region; the airbag array composed of the plurality of airbags and the plurality of air channels are arranged on the base; the plurality of air guide pipes are arranged in the base; one end of each air guide pipe is communicated with the corresponding air channel and the other end of each air guide pipe extends out of the cushion and is provided with a connector; each air guide pipe is provided with a respective valve; fluid of the automatic pressure adjusting device is communicated with all connectors of the plurality of air channels and is electrically connected with each valve on each air guide pipe so that the pressure adjusting device can inflate or deflate each air guide pipe.

Description

technical field [0001] The invention relates to a cushion, in particular to an automatic pressure-regulating pressure sore-preventing 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 pressu...

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
