Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a bed sore prevention mat for preventing bedsores that occur when going to bed during long-term medical treatment.

[Background technology]

To prevent bedsores, it is effective to avoid local pressure, change the body position frequently, and keep the surface of the body that comes into contact with the bedding dry, but it is a burden for nurses to do this. is large. For this reason, mats for preventing bedsores have been proposed, such as the one shown in Japanese Patent Publication No. 53-27661. The device disclosed in this publication has a large number of tubular air sacs that can be expanded and contracted arranged in parallel, and elastic striations are arranged between the air sacs.When the air sacs are inflated, the air sacs support the body. When the air sac is deflated, the striations support the body, and the point of support for the body changes as the air sac expands and contracts.Also, a minute exhaust hole is provided on the top of the air sac to support this body. Air is blown out from the exhaust hole. The expansion and contraction of the air sac here, together with the elasticity of the air sac, is effective in avoiding local pressure on the body, and the jet of air is effective in keeping the body in a dry state. It has the following problems. In other words, since the air sac expands and contracts, there is a problem in that when the air sac is contracted, air cannot be ejected from the air sac, and even if the configuration is such that air is ejected not from the air sac but from the striations. By the way, the point at which air is ejected is limited to the position where the strip exists, and it is not possible to eject air from the entire surface of the pine. It was not possible to fully demonstrate the effect.

[Purpose of invention]

The present invention was devised in view of these points, and its purpose is to solve the problems in the conventional example described above, and to move the support point of the body and change the body position by expanding and contracting the air sac. Another object of the present invention is to provide a mat for preventing bedsores that can sufficiently prevent bedsores due to the air flow ejected from the entire surface.

[Disclosure of invention]

Therefore, the present invention is composed of a first air bag having a micro exhaust hole on the upper surface and connected to a continuous air supply means, and a second and third air bag connected to an intermittent air supply means. The second air sacs and the third air sacs are formed of a plurality of air sacs connected by a connecting air sac part, and the second air sacs and the third air sacs are provided alternately and in parallel, and the first air sacs are provided alternately and in parallel. The air sac is characterized in that it is provided on the upper surface of the second air sac and the third air sac, and air is blown out from the first air sac installed on the upper surface of the second air sac and the third air sac. This is what I did. The continuous air supply means for supplying air to the first air sac may be an air pump or a compressor, and the intermittent air supply means for supplying air to the second and third air sacs may be composed of an air pump or compressor and a valve such as a three-way valve. can.

The present invention will be described in detail below based on illustrated embodiments. In the figure, 1 is a first air bag made of a soft material, and this first air bag 1, which is placed on the entire upper surface of the pine, has a large number of minute exhaust holes 4 formed over almost the entire surface of the upper surface, and is connected to It is connected through port 5 to a continuous air supply means such as an air pump.
The second tube is made of a tubular material that can expand and contract.
A plurality of air sacs 2 and third air sacs 3 are arranged alternately in parallel on the lower surface of the first air sac 1, and each second air sac 2 is connected at one end, and each third air sac 3 is connected at the other end. The second air bladder 2 and the third air bladder 3 are connected to an intermittent air supply means consisting of an air pump and a control valve through a connection port 8 and a connection port 9, respectively. ing. Incidentally, the first air bladder 1 may be divided into two parts according to the division into the second air bladder 2 and the third air bladder 3.
It is only necessary to connect the two parts separated at the connection port 5.

However, in the case of a lever, if air is supplied to the second air sac 2 and the second air sac 2 is inflated, it protrudes above the third air sac 3 as shown in Fig. 2, and the second air sac 2 supports the body. By removing air from the second air sac 2 and contracting it, at the same time supplying air to the third air sac 3, the third air sac 2 will open as shown in FIG.
The air sac 3 projects higher than the second air sac 2, and the third air sac 3 supports the body. In either state, air is blown out from the exhaust hole 4 of the first air sac 1 arranged on the upper surface of the second air sac 2 and the third air sac 3, and the body is kept dry by this air flow. It is. Here, the second air sac 2
The alternate expansion and contraction of the second air sac 2 and the third air sac 3 causes the support point of the body to move, and the air flow sent into the second air sac 2 and the third air sac 3 deforms these air sacs. The body position is changed by giving exercise. Furthermore, since the first air sac 1 is located on the entire upper surface of the pine, each part of the body is in contact with the air constantly blown out from the first air sac 1.

[Effect of idea]

As described above, in the present invention, local compression is caused by the movement of the body support point due to the alternate expansion and contraction of the second and third air sacs, and the deformation movement of these air sacs due to the air flow within the second and third air sacs. In addition, the air blowing out from the first air sac constantly keeps each part of the body in a dry state, making it extremely effective in preventing bedsores.

[Brief explanation of the drawing]

FIG. 1 is a plan view of an embodiment of the present invention, and FIGS. 2 and 3 are cross-sectional views of the same, in which 1 is a first air sac, 2 is a second air sac, 3 is a third air sac,
4 indicates an exhaust hole.
