Air Mattress

Abstract

Provided is an air mattress capable of preventing the occurrence of decubitus ulcers in a person lying on the air mattress. The air mattress has a plurality of air cell groups made from a plurality of bladder-shaped cells and lined up with respect to the lengthwise direction of the air mattress so as to support at least a head area, shoulder area, back area, buttock, thigh area, knee area, and heel area of a person lying on said air mattress; an air supply / release pump; and an air tube connecting said bladder-shaped cells and said air supply / release pump in one or a plurality of independent first systems for each of the air cell groups out of said air cell groups and one or a plurality of independent second systems for each of specific bladder-shaped cells out of the plurality of air cell groups. Air supply / release by the air supply / release pump is controlled by a controller, and the pressure in at least air cell groups corresponding to a back area and a thigh area is greater than the pressure in an air cell groups corresponding to a buttock area.

Description

technical field [0001] The invention relates to an air mattress, in particular to an air mattress capable of preventing people lying on the air mattress from developing bed sores. Background technique [0002] Conventionally, as an air mattress for preventing decubitus, there are air mattresses disclosed in Patent Documents 1 and 2, for example. Patent Document 1 discloses such a technology: In an air mattress formed by arranging a plurality of bag-shaped air cells on the bottom plate, all the air cells are separated into an upper layer and a lower layer by a partition, and the upper layer and the lower layer are used All air cells are expanded or contracted respectively. [0003] In addition, Patent Document 2 discloses a technology in which a plurality of air cells are arranged along the longitudinal direction of an air mattress inside a holding member formed of an elastic material, and pressure in the air cells is adjusted to prevent decubitus ulcers. [0004] In additi...

AI Technical Summary

Problems solved by technology

Therefore, like Patent Document 1, the air mattress acting on the buttocks of the person lying on the air mattress has a large rebound force and cannot completely prevent the occurrence of decubitus ulcers.

[0010] The technology in Patent Document 3 is to prevent the rebound force of the air mattress from acting on specific parts where bedsores occur, not to prevent bedsores
