持用クッション機構に関するものである。[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a method for preventing the occurrence of bed sores by alternately decompressing and supporting the bodies of patients, etc. in groups. This invention relates to a support cushion mechanism.

る。The body of the patient, etc. is alternately reduced/supported in each group.
・As a conventional body support mechanism, there is an air mat in which a large number of air sacs that can be inflated and deflated are arranged vertically and horizontally, and these air sacs are connected in groups to be inflated and deflated. . In such an air mat, pressurized air is supplied by an air pump to pressurize the air sacs in one group, and the air sacs in the other group are depressurized by removing air, and this operation is repeated alternately. This is intended to reduce the pressure of the pressurized body part after a predetermined period of time has elapsed, thereby preventing obstruction of blood flow 111'A due to continued pressurization for a long time.

等の問題点もある。However, since air mats pressurize and depressurize by letting air in and out in this way, it would be foolish to shorten the cycle of pressurization and depressurization by more than a certain amount, and the blood loss during the pressurization period. There is a problem in that flow obstruction continues for a relatively long time. In addition, air mats are made of airtight resin sheets.
Because it is composed of
It has a strong tendency to accumulate moisture, so there are problems when using it in patients who are bedridden for a long time with fever and sweating, or when using it in the summer.
The air support also causes problems such as seasickness and discomfort when sleeping.

しいという問題点がある。There is also a support Ia structure in which a large number of protruding support parts are immovable for each group, but in conventional such mechanisms, the distribution of groups is fixed in advance. So,
There is a problem in that it is difficult to obtain a support pressure distribution that is suitable for each supine state.
本発明はこれらの問題点を解決することを目的とするも
のである。The present invention aims to solve these problems.

する構成としたものである。The configuration of the present invention and its basic concept are shown in Figure 1(a).
(b) 1. To explain based on (c), according to the present invention, a body support part S is constructed by arranging a large number of elastic supports 2 vertically and horizontally, which can adjust the support pressure against the load applied to the support part 1. The support body 2 is provided with a pressure sensor 3 for detecting the support pressure (and the drive control means 4 of the support body 2 is configured to compare the support pressure detected by the n-ca sensor 3 with a set pressure). A first update control stage 6 for updating the dynamic f1 condition at predetermined time intervals, and a driving means 7 for controlling 611 by the first update control stage 6 are provided. During the period, the operating conditions are updated so that the supporting pressure of the two groups of supports whose supporting pressure is above a predetermined value is decreased, and the supporting pressure of the two groups of supports whose supporting pressure is below a predetermined value is increased. Accordingly, the driving means 7 is controlled.

示している。In the above configuration, the 80 body weight of a patient lying supine on the body support surface S is dispersed and elastically supported by a large number of supports 2 via the support section 1. Suppose now that a predetermined period of time has passed since the start of support, and the body is being supported in the state shown in FIG. 1(b). In this figure, the support pressure of group a, where the support surface 1 is drawn upward, is higher than that of group a, which is drawn below the square.

を示すものである。In the above state, the drive control means 4 detects the support pressure of each support body 2 via the pressure sensor 3, and the comparison means 5 compares the support pressure with the set pressure. In FIG. 1, reference numeral 9 indicates a support pressure input section, and 10 indicates a pressure setting section.

号である。When the above state has passed for a predetermined period of time, the update control means 6 issues an update control signal to the drive means 7 and controls it. This update control signal is used during the pre-update period, that is, during the first
During the period of the state shown in Figure (b), the support force of the group a of the supports 2 whose support pressure is above a predetermined level is reduced, and the support force of the supports 20 whose support pressure is below a predetermined level during the period is reduced. This signal controls the drive means 7 to increase the support pressure of the group.
従って、支持体２の群ａ、ｂは前）ホした更新制御信号
に基づいて駆動手段７により制御され、第１図（Ｃ）の
状態に移る。Accordingly, the groups a and b of the supports 2 are controlled by the drive means 7 based on the update control signal mentioned above, and the state shifts to the state shown in FIG. 1(C).
こうして、支持体２の群ａに対応して、比較的高い支持

: Depression blood and hyperemia occur, and 25~30~+llO
It is said that ischemia progresses due to arterial blood flow resistance when the blood pressure is exceeded, and this is one of the causes of decubitus ulcers.

る。Therefore, as mentioned above, by alternately decompressing parts of the body,
By ensuring that the pressure during decompression does not exceed the above-mentioned pressure, even if the pressure is supported at a higher pressure than the above-mentioned pressure during pressurization, obstruction of blood circulation due to continued pressurization for a long time can be prevented. By doing so, it is possible to prevent the occurrence of decubitus sores.

As shown in FIG. 2, an air cylinder device 14 connected to both ends of the coil spring 10 may be used as appropriate. Further, the coil springs 10 constituting the forced displacement means 9 can be arranged by storing and supporting each coil spring 10 independently in a support pocket or the like, so that the coil springs 10 can be arranged vertically and horizontally. As disclosed in the publication, a coil spring is molded with a soft cylindrical body, etc., and this is fitted into a circular hole of an elastic flexible board to support it, or the structure shown in FIGS. 2 and 3 is used. J: It is preferable to provide a configuration in which the displacement of each coil spring 10 is not hindered by the adjacent coil springs 10 as much as possible, such as by loosely coupling the coil springs 10 adjacent to each other. Furthermore, the arrangement shape of the large number of coil springs 10 may be a mesh shape, a zigzag shape, etc., in which they are arranged regularly and continuously, or the arrangement density of the parts may be coarsely or densely arranged as appropriate.

For example, the cushion body and the covering member 22 can appropriately disperse the pressure of the elastic support 2 such as the coil spring 10 against the body so that the body does not feel pain, and can also prevent the pressure of the elastic support 2 such as the coil spring 10 etc. In order to reduce the interference as much as possible,

In addition to being configured with hardware, it can be configured as appropriate, such as as firmware using a microcomputer or the like. For example, the support pressure detected by the pressure sensor 3 and the set pressure may be compared at an appropriate point in the period before updating, but it is important to prevent malfunctions when the support pressure changes from moment to moment. In order to do so, the support pressure to be compared may be compared as an average value within the period, or the support pressure detected at the appropriate point in time may be temporarily held in a storage means, and the held support pressure may be It is possible to have a configuration in which the supporting pressures are comparable.
