Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a supply/exhaust type mat suitable for use in caring for the elderly and patients.

[Conventional technology]

Conventionally, an airtight bag-shaped mat containing countless porous particles has been developed, and after the patient lies down on the mat, the air can be evacuated from the mat to adjust to the patient's body shape. This is used when the above-mentioned mats are stiffened while still together and the patient is transported along with the mats.

[Problem that the invention seeks to solve]

By the way, when bathing or showering a patient on the mat, the patient must be transferred to the bathtub, which is a problem in that it takes a lot of effort.

The present invention attempts to solve these problems, and aims to provide an air supply/exhaust type mat in which the mat on which a patient is placed can itself be used as a bathtub.

[Means for solving problems]

In order to achieve the above object, the air supply/exhaust type mat of the present invention is provided with an airtight bag-shaped rectangular mat containing numerous porous granules therein, and an air supply/exhaust means for the mat. Notches in the shape of approximately right-angled isosceles triangles are formed at the four corners, and the flexible sheet is stretched liquid-tightly between the two opposing sides of the notches, and the inside of the mat is formed in the right-angled isosceles triangle shape. It is characterized in that it is divided into four compartments by a pair of partitions diagonally connecting the vertices of the equilateral triangular notches, and each compartment is provided with a valve as the supply/exhaust means.

[Effect]

In the above-mentioned air supply/exhaust type mat of the present invention, when a patient lying on the mat is bathed, the four sides of the mat are raised up, and then the air is evacuated from the inside to cause the numerous porous particles to nestle together. By stiffening the mat while moving, the entire mat is formed into a box-like body with an open top.

At that time, the mat is divided into 4 sections with a pair of diagonal partitions.
Since it is divided into individual compartments and each compartment is equipped with a valve, each valve can be used in turn to perform the exhaust operation on each side of the pine. During work, each side can be folded and stiffened in sequence in an efficient manner.

Furthermore, since a flexible sheet is liquid-tightly provided at the joints between the four rising sides as described above, even if warm water for bathing is poured into the box-shaped body, leakage will not occur. There isn't.

After bathing, the hot water in the box-shaped body is drained by a drain pump or by opening a valve on a drain pipe connected to an appropriate location on the mat.

It is also possible to use the above-mentioned mat as a tilting bed, in which case only the left and right sides of the above-mentioned mat are raised by the exhaust air, which hardens the entire mat, and then bedding is placed inside and the patient is made to lie down. Air can be supplied to only one of the expandable and deflated air chamber members provided on the left and right sides of the underside of the mat, making it tilt, or alternately supplying and exhausting air to the left and right air chamber members to make them swing. will be carried out.

〔Example〕

Hereinafter, an air supply/exhaust type mat as an embodiment of the present invention will be explained with reference to the drawings. Fig. 1 is a plan view thereof, Fig. 2 is a sectional view taken along the - arrow in Fig. FIG.

As shown in Figures 1 and 2, in an airtight bag-shaped rectangular mat 1 containing numerous porous particles 1a made of polystyrene etc., approximately right-angled isosceles triangular shaped mats are placed at the four corners of the mat 1. A notch 1b is formed.

A flexible sheet 2 such as a rubberized cloth or a synthetic resin sheet is stretched in a liquid-tight manner between the two opposing sides of each notch 1b.

The inside of the mat 1 is partitioned into four compartments by a pair of partitions 1c, 1c that diagonally connect the vertices of the right isosceles triangular notches 1b.
A valve 3a as a supply/exhaust means for each compartment,
3b, 3c, and 3d are provided.

Further, on the left and right sides of the lower surface of the mat 1, two inflatable and deflated air chamber members 4 each made of a flexible wall such as a rubberized cloth or a synthetic resin sheet are arranged in the front and rear. Part 4
Also, valves (not shown) are installed as air supply/exhaust means, respectively.

With the above-mentioned configuration, the patient is placed lying down on the mat 1 as in the past, and then the valve 3 is transferred from the same mat 1.
a, 3b, 3c, and 3d, the numerous porous granules 1a inside are brought together, and the mat 1 is made rigid according to the patient's body shape, allowing the patient to be transferred. .

In addition, when bathing the patient while placed on the mat 1, when bending and raising the four sides of the mat 1, use one valve 3a, 3b, 3c, and 3d in sequence to exhaust the air for each side. This allows one person to efficiently bend and stiffen each side in sequence as shown in FIG. 2.

When the mat 1 is formed as a box-like body with an open upper part in this way, the flexible sheet 2 is stretched in a liquid-tight manner at the joints between the four rising sides, so that the above-mentioned Even if warm water for bathing is poured into the box-shaped body, no leakage will occur.

After bathing, the hot water in the box-shaped body is drained by a drain pump (not shown) or by opening a valve on a drain pipe connected to an appropriate location on the mat 1.

When storing the mat 1 after use, it is sufficient to open each valve 3a, 3b, 3c, and 3d to supply natural air to the four compartments of the mat 1. Since the rigid state is released and the mat 1 becomes flexible, the mat 1 can be appropriately folded and stored in a compact state.

It is also possible to use the mat 1 as a tilting bed. In that case, only the left and right sides of the mat 1 are raised and the entire mat 1 is made rigid by exhaust air, and then a mat tress 5 is installed inside the bed as shown in Fig. 3. , the patient A is put to bed with bedding such as a mattress 6, a comforter 7, and a pillow 8 placed therein.
By supplying air to only one side of the air chamber and tilting the mat 1, or by alternately supplying and discharging air to the left and right air chamber members 4 by reversing the direction of an electric pump equipped with a changeover switch with a timer (not shown). , Matsuto 1
This is done by shaking the

In this way, the raised left and right sides of the mat 1 serve as fences, so even if the mat 1 tilts, the patient A will not fall.

〔Effect of the invention〕

As described in detail above, the air supply and exhaust type mat of the present invention provides the following effects and advantages.

(1) As in the past, by evacuating the patient from the mat while the patient is lying on the mat, you can adjust the mat to the patient's body shape and transfer the patient. The mat can be used as a bathtub for bathing, and in this case, since the mat has substantially isosceles right triangular notches formed at the four corners, it is easy to raise the four sides of the mat.

(2) When using a mat as a bathtub, the mat is divided into four compartments by a pair of diagonal partitions, and each compartment is equipped with a valve. It is possible to perform exhaust operation on each side of the mat using the
This allows one person to efficiently bend and stiffen each side in sequence.

(3) When storing this mat after use, it is sufficient to open each valve to supply natural air to the four compartments of the mat, which releases the rigid state of the mat and makes it flexible. Therefore, the mat can be folded up and stored in a compact state.

(4) Since flexible sheets are stretched in a liquid-tight manner in the notches at the four corners of the mat, water leakage from the four corners of the mat can be sufficiently prevented when the mat is used as a bathtub.
