Air Mattress

Abstract

Provided is an air mattress that prevents bedsores from forming on a person lying thereupon. Said air mattress has: a plurality of air cell groups in the long direction of the air mattress, positioned corresponding to at least the head, shoulders, back, buttocks, thighs, knees, and heels of a person lying on the air mattress, each air cell group comprising a plurality of pouch-shaped cells; an air intake / removal pump; and air tubes that connect the pouch-shaped cells to the air intake / removal pump, said air tubes comprising one or more independent first lines, for each air cell group, and one or more independent second lines, for each of specific pouch-shaped cells in multiple air cell groups. A control unit controls the intake and removal of air by the air intake / removal pump such that, at least, the pressure in the air cell groups at the back and thighs is greater than the pressure in the air cell group at the buttocks.

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
