Air mattress

Abstract

Provided is an air mattress in which internal pressure can be controlled according to the movements of a bed. The air mattress is provided with a plurality of air cell groups lined up in the lengthwise direction of the air mattress, each of which groups is made from a plurality of bladder-shaped cells; an air supply/release pump; and an air tube connecting the air cell groups and the air supply/release pump in an independent system for each air cell group of two or more air cell groups out of said air cell groups. Air supply/release by the air supply/release pump to each of the air cell groups is controlled by a controller, at least a part of information needed to control the bed is received from an external sensor for detecting such information, and air supply/release by the air supply/release pump for each of the air cell groups is controlled on the basis of the received information.

Description

technical field [0001] The present invention relates to an air mattress, and more particularly to an air mattress placed on a pallet of a bed and capable of controlling internal pressure based on information from an external sensor. Background technique [0002] Conventionally, as an air mattress, there is an air mattress disclosed in Patent Document 1, for example. Patent Document 1 discloses a technique in which air bags are provided corresponding to the thighs, left and right shoulders, or buttocks of a person lying supine on the base pad of an air mattress, and the air supply and exhaust to these air bags are controlled by a control device. , to assist the breathing action of a person lying on the air mattress. [0003] In addition, as a mattress to be used on a bed, for example, there is a mattress disclosed in Patent Document 2. Patent Document 2 discloses a technique of controlling the air pressure inside the mattress according to the physique, weight, position or m...

AI Technical Summary

Problems solved by technology

Therefore, the part of the air mattress 1 corresponding to the person's buttocks is pushed and the bottom of the large sink is bulged, and the person on the air mattress feels uncomfortable in the buttocks due to the hardness of the support plate of the bed.

In this case, when the person on the air mattress 1 is, for example, a patient who has been lying down for a long time, there is a problem that the buttocks of the patient or the like may develop decubitus ulcers due to constant pressure.

[0007] That is, there has been a problem in the past that, as shown in the above-mentioned Patent Documents 1 and 2, in an air mattress installed on a flat place, in order to make the air mattress function independently, the sensor monitors the movement of the person on the air mattress. Detect information such as body weight, and control the internal pressure based on the detection results. As shown in the above example, if the bed has a specific function such as the lifting function of the backrest, etc., the pressure control of the air mattress cannot be linked with the function of the bed. , resulting in bottom bulging etc.

[0008] In addition, as shown in Patent Documents 1 and 2, when many sensors are provided on the air mattress, there is also a problem that the manufacturing cost of the air mattress becomes high.
