圧力制御方法に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a variable support pressure type body support device which aims to prevent the occurrence of bedsores by alternately supporting the body of a patient, etc. by reducing the pressure in each group. The present invention relates to a support pressure control method for a cushion mechanism.

る。[Prior art and its problems] A conventional body support mechanism that supports the body of a patient by alternately depressurizing each group includes a large number of inflatable and deflated air sacs arranged vertically and horizontally. There is an air mat that allows these air sacs to communicate with each other in groups so that they can be expanded and deflated. Such an air mat supplies pressurized air using an air pump to pressurize the air sacs in one group, and at the same time depressurizes the air sacs in the other group by removing air. By repeating this alternately, the pressurized body part is depressurized after a predetermined period of time has elapsed, thereby preventing obstruction of blood circulation due to continued pressurization for a long time.

時の異和感等の問題点もある。 However, since air mats perform pressurization and depressurization by taking in and out air in this way, it is difficult to shorten the pressurization and depressurization cycle beyond a certain degree, and the blood flow during the pressurization period is reduced. The problem is that the inhibition continues for a relatively long time. Also,
Air mats are made of airtight resin sheets, so they tend to accumulate heat and moisture between the parts of the body that come into contact with them. There are problems with the use of air support, and furthermore, there are problems such as seasickness and discomfort when sleeping.

力分布を得るのが難かしいという問題点がある。 There is also a support mechanism in which a large number of protruding support parts are temporarily moved up and down in groups, but in conventional such mechanisms, the arrangement of the groups is fixed in advance, so it is difficult to move the support parts up and down for each group. There is a problem in that it is difficult to obtain a support pressure distribution that is suitable for the conditions.
本発明はこれらの問題点を解決することを目的

In the above configuration, the weight of a body 8 such as 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 surface 1. Suppose now that a predetermined period of time has passed since the start of support, and the body is supported in the state shown in FIG. 1b. In this figure, the support pressure of group a, where the support surface 1 is drawn upward, is higher than that of group b, which is drawn downward.

る。 When the above-mentioned state has passed for a predetermined period of time, the update control means 6 issues an update control signal to the drive means 7 to control it. This update control signal lowers the support pressure of the group a of the supports 2 whose support pressure is higher than a predetermined value in the period before the update, that is, the period of the state shown in FIG. This is a signal for controlling the drive means 7 to increase the support pressure of the group b of the supports 2 whose pressure is below a predetermined value.
従つて、支持体２の群ａ，ｂは前述した更新制

ができる。 By continuously performing the above operations at predetermined time intervals, parts of the body supported by relatively high support pressure are alternately depressurized. In general, if the pressure applied to any part of the body exceeds 10 to 15 mmHg, venous blood flow resistance will cause congestion and congestion, and 25
It is said that when the temperature exceeds 30 mmHg, ischemia due to arterial blood flow resistance progresses, and this is one of the causes of pressure ulcers. Therefore, as mentioned above,
By alternately depressurizing parts of the body so that the pressure at the time of decompression does not exceed the above-mentioned pressure, even if the body is supported at a higher pressure than the above-mentioned pressure during pressurization, it will not be possible to apply pressure for a long time. By preventing obstruction of blood circulation due to continued pressure, the occurrence of pressure ulcers can be prevented.

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 is supported by fitting into a circular hole of an elastic flexible board, and also as shown in FIGS. 2 and 3.
It is preferable to provide a configuration in which the displacement of each coil spring 10 is not hindered as much as possible by adjacent coil springs 10, such as by loosely coupling adjacent coil springs 10 as in the configuration shown in the figure. preferable. Furthermore, the shape of the arrangement of the large number of coil springs 10 may be such that they are regularly arranged in a continuous manner such as a mesh shape or a staggered shape, or the arrangement density of the parts may be coarsely or densely arranged as appropriate. good.

ことができる。 Next, each component in the drive control means 4 described above can be configured as appropriate, such as by being configured by hardware or by 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 is configured to be compared as an average value within the period, or the support pressure detected at the appropriate time is temporarily stored in a storage means,
It is possible to adopt a configuration in which this held support pressure is used as the support pressure to be compared. In addition, when the control is performed in a time-division manner using a multiplexer or the like, a storage means is provided for storing the position of the support 2 to be controlled on the matrix, and this storage means allows the above-mentioned control to be performed at the time of updating. You can do it as you like.

As described above, in the support pressure control method of the present invention, a body support surface is constructed by arranging a large number of elastic supports whose support pressure can be adjusted vertically and horizontally, and the support pressure is alternately reduced for each group. This depressurization is not performed for each group whose arrangement is fixed in advance as in the past, but instead of performing the depressurization for each group whose arrangement is fixed in advance, the support that actually has a high support pressure is applied to the next support regardless of its history. Since this is performed when the pressure is updated, it is possible to effectively prevent the continuation of high support pressure for a long period of time.This prevents the occurrence of pressure ulcers by preventing the obstruction of blood circulation due to the continuation of pressure for a long time. There is an effect that can be done.
