Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to an air bag device used for tilting a mattress, and is particularly useful for assisting patients in turning over and preventing the occurrence of pressure sores. The present invention relates to a combination type air bag device suitable for use in a tilting mat for use in water storage.

[Conventional technology]

Conventionally, methods for tilting the bed include methods in which a mat support member is pivotally supported on the bed frame and swung mechanically, and methods in which an air bag with a triangular cross section is inserted into the underside of the bed. It is being

[Problem that the invention attempts to solve]

By the way, in the conventional means of pivotally supporting the mat support member with respect to the base of the bed, the driving device for tilting the mat support member is large-scale, and a safety mechanism such as a stopper is required.
This has the problem of complicating the structure and increasing costs.

In addition, in the case of air bags with a triangular cross section, there are problems in that it takes time to arrange many air bags on the left and right, and the amount of air supply and exhaust is large, requiring a large-capacity air pump. .

The present invention is an attempt to solve the above-mentioned problems, and is a combination air bag device for a tilting mat that has a simple structure and can easily assist the patient in turning over and rocking with a small air pump. The purpose is to provide.

[Means for solving problems]

In order to achieve the above object, the combined air bag device for a tilting mat of the present invention consists of two pairs of air bag devices that are combined to face each other on the left and right, and each air bag device is A plurality of pairs of left and right air bags connected in the vertical direction are provided in the vertical direction, and a connecting sheet is provided that connects the plurality of sets of air bags with a mutual interval that is approximately the same as the vertical dimension of the air bags, and the above-mentioned The air bag is characterized by being provided with a bendable connecting member that interconnects the tip ends of the pair of left and right air bags bent at the bending portion, and an air supply/exhaust means for the air bags.

[Effect]

In the above-mentioned combination air bag device for tilting mats of the present invention, when using the combination air bag device, two sets of air bag devices are
They are combined so as to face each other left and right, and inserted under bedding such as a mat, and air is supplied to the air bag in one of the air bag devices by the air supply/exhaust means.

As a result, the pair of left and right air bags in one air bag device are inflated together and deformed so as to open their respective tips due to the repulsive force at the mutual contact surfaces near the folded portions between them.

Therefore, bedding such as a mat placed on the device can be sufficiently tilted even with a small volume of air supply.

In addition, since the two sets of air bag devices are used so as to face each other on the underside of the mat, and one air bag is fitted between the other air bags, the two sets of air bags are used. By supplying air to one side of the device and exhausting air from the other side, the mat is tilted and swung alternately in the left and right directions.

〔Example〕

Hereinafter, a combination type air bag device for a tilting mat as an embodiment of the present invention will be explained with reference to the drawings. Fig. 1 is a plan view showing the unfolded state of one set of air bag devices, and Fig. 2 is its usage state. FIGS. 3A, 3B, and 3C are explanatory diagrams showing the human body support aspect of the modified example.

This combination air bag device for tilting mats is the first
After assembling the air bag device as shown in the figure, the two sets of air bag devices are used so as to face each other on the left and right sides as shown in FIG.
Each air bag device is provided with three pairs of left and right triple-type air bags 2, 2 in the vertical direction, which are connected in the horizontal direction via a bending part 1.
are connected by a connecting sheet 3 with a mutual distance d that is approximately the same as the longitudinal dimension l of the air bag 2.

A bendable sheet-like connecting member 4 connects the respective tips of the pair of left and right air bags 2, 2 bent at the bending portion 1 to each other with a string or a hook-and-loop fastener (velvet fastener).
(See Figures 1 and 2).

Further, as a supply/exhaust means 5 for each air bag 2, a hose 5b having a valve 5a is connected to the air bag 2. In addition, air bags 2 are paired on the left and right,
2 are formed so as to communicate with each other.

When using this device, as shown in FIG. 2, the pair of left and right air bags 2, 2 are bent at the bending portion 1, and the distal ends of each air bag 2, 2 are connected by a connecting member 4.

Then, by inserting this device under the mat 6 serving as bedding and supplying air to each air bag 2 with an air pump (not shown), the pair of left and right air bags 2, 2 connected to each other, While inflating together, due to the action of repulsive force at the mutual contact surfaces near the folded part 1 between them, even with a small volume of air supply, the tips of the air bags 2, 2 on the opposite side to the folded part 1 are Transform so that they open up to each other. (See Figure 2) Therefore, the mat 6 placed on top of this device
The mattress 6 is now tilted, and the body position of the patient lying on the mattress 6 can be changed.

Also, below the mat 6, two sets of air bag devices are arranged so as to face each other, and the air bags 2 of one device are partially fitted between the air bags 2 of the other device in the vertical direction. By alternately supplying and exhausting air to the air bags 2 of the left and right devices, the mat 6 is tilted and swung alternately in the left and right directions.

Although this rocking motion is performed very gently, it assists the patient in turning over on the mat 6, thereby preventing the patient from developing pressure sores.

Figures 3a, b, and c show the cases in which the air bags 2 are used in this device, when 4 sets of air bags 2 are installed on one side in a 2-air system, when 3 sets are installed on one side in a 3-air system, and when the air bags 2 are used in a 5-air system. The figure shows how each part of the human body is supported when two sets are provided on one side. As shown in FIG. 2, as the mat 6, an airtight bag 6a containing countless small particles of foamed resin can be used, and the shape of the mat 6 is changed by exhausting air from the inside of the airtight bag 6a. , fences 6b may be formed on both sides thereof.

[Effect of idea]

As described above in detail, the combination air bag device for tilting mats of the present invention provides the following effects and advantages.

(1) By bending the left and right pairs of air bags through the bending portions and connecting them with a connecting sheet, each air bag device can be easily assembled.

(2) By supplying air to the pair of left and right air bags using a supply/exhaust means, the tips of the left and right air bags can be opened to each other even with a small volume of air supply due to the repulsive force of the mutual contact surfaces near the bends. By deforming it in this way, it is possible to make the bedding such as a mat on it sufficiently inclined.

(3) Two sets of air bag devices are combined to face each other on the left and right under the mat, and the air bags of one device can be inserted between the air bags of the other device, so the mat The rocking action of alternately tilting the mat in left and right directions can be performed efficiently, and the occurrence of pressure sores on patients on the mat can be prevented.
