Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bedsore prevention mat.

[0002]

2. Description of the Related Art Conventionally, there are sick people and elderly people who have to remain bedridden for a long period of time. Such bed users (hereinafter referred to as "user M '") have a blood circulation disorder in a part of their body. Since there is a risk of causing so-called bed sores, a bed sore prevention mat X is sometimes used as shown in FIG. In the figure, B'is a bed, a mattress 100 is laid on the bed B ', and a bed slip prevention mat X is laid on the mattress 100 for use.

As shown in FIG. 2, a mat X for preventing bedsores of this type forms an air cell group 200 by arranging a large number of air cells 110 and 120 in a plane direction on a synthetic resin sheet S '. , The air cell group 200 is divided into two systems in which air supply and discharge are performed at alternate timings (first cell group
210 and a second cell group 220), an air cell 110 belonging to the first system and an air cell 120 belonging to the second system are arranged adjacent to each other.

In FIG. 2, reference numeral 310 is a first supply / discharge pipe which constitutes a first supply / discharge system, and 320 is a second supply / discharge pipe which constitutes a second supply / discharge system. Connected to the pump 500. Then, the air cells 110, 120 are in communication with the first and second supply / discharge pipes 310, 320 via the communication pipe 150.

It should be noted that the flow path switching valve 400 is 15-20.
It is controlled by a control device (not shown) so as to switch the air supply passage of the air every predetermined time set in minutes, and when the air supply passage of the air communicating with the pump is closed, the atmosphere is opened to the contrary. It is configured to be.

With the above structure, when the pump 500 is driven, the first cell group 210 and the second cell group 220 are alternately filled with air, and the cell group on the side not filled with air is filled. Each cell (outlined cells in the circle shown in FIG. 2) shrinks when the weight of the user M ′ is added.

Therefore, the weight is not concentrated on one part of the body of the user M ', and congestion is prevented and bed sores are prevented.

[0008]

However, the conventional floor sore prevention mat X has the following problems.

That is, the conventional bedsore prevention mat X is
Usually, as disclosed in Japanese Utility Model Laid-Open No. 145718/1983, for example, two sheets S ′ provided with a film made of a heat-weldable synthetic resin on the inner surface of a fabric are overlapped to form a peripheral portion of these sheets. Each of the air cells 110 and 120 is simply welded to each other, and the air cells 110 and 120 themselves are simply partitioned and formed, and the air cells 110 and 120 themselves do not have any rigidity, and when they are deflated, the air cells 110 and 120 are in a substantially petancho state. It was something that would end up.

Therefore, for example, when air is alternately supplied to and discharged from the first and second cell groups 210 and 220, it takes time to supply air again.

Further, the communication pipe 150 connecting the air cells 110 and 120 to each other is also heat-welded to the sheet S. Especially, if the film of synthetic resin or the communication pipe 150 itself is thin. Since there is a risk of blocking the flow path during heat welding, careful work is required, and the method of forming the sheet S ′, that is, the method of forming the floor slip prevention mat X itself is complicated.

An object of the present invention is to provide a floor slip prevention mat which can solve the above problems.

[0013]

Therefore, in the present invention according to claim 1, a large number of air cells are arranged in parallel in a plane direction to form an air cell group, and the air cell group is supplied and discharged with air. Is divided into a plurality of systems that are performed with a predetermined timing difference, and in a floor slip prevention mat in which air cells belonging to one system and air cells belonging to another system are arranged adjacent to each other, the air cells are formed by a molding material. In addition to being able to shorten the air supply time for forming and expanding, it also reduced the amount of mold deformation during exhaust.

Further, in the present invention according to claim 2, the air cell is formed in a rectangular box shape.

Further, in the present invention according to claim 3, the air cells are arranged in a grid to form an air cell group.

Further, in the present invention as set forth in claim 4, the air cells forming one air cell group are communicated with each other through a communicating pipe integrally molded with the air cells.

Further, according to the present invention, the sheet materials, in which a plurality of air cells having lower openings formed of the molding material are juxtaposed, are abutted and connected so that the openings are superposed.

Further, in the present invention according to claim 6, the communication pipe is formed in a cross shape.

[0019]

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, a large number of air cells are arranged side by side in a plane to form an air cell group, and a plurality of air cells are supplied and discharged with a predetermined timing difference. In a floor slip prevention mat in which air cells belonging to one system and air cells belonging to another system are arranged so as to be adjacent to each other in a system, the air cells are formed of a molding material to supply air for expansion. The time can be shortened, and the amount of mold deformation during exhaust is reduced.

That is, for example, a synthetic resin material is used as a molding material, and this is molded to form a sheet in which a large number of air cells are arranged side by side in the plane direction, so that the floor slip prevention mat can be easily manufactured, In addition, since the molding is performed, it is possible to prevent the air cell from losing its shape, it is possible to shorten the air supply time for expanding the air cell, and it is possible to prevent the deformation of the air cell during exhaust.

Therefore, when the air cells that have held the user's body are exhausted and withered, the adjacent air cells instantly expand and hold the body, so that the body moves up and down. It does not spoil the usability.

In particular, it is preferable that the air cell is formed in a rectangular box shape. In such a form, the air cell has a side wall portion standing upright from the sheet material on the periphery,
Since it has a firm waist, it is possible to reduce the amount of shape collapse when exhausted. Further, cleaning of dust or the like that tends to collect in the gaps between the air cells is extremely easy because the air cells do not cover each other.

When the air cells are of rectangular box type, the air cell groups are arranged in four directions on the sheet so as to form a grid pattern, that is, a grid pattern, and the air supply / discharge is performed at a predetermined timing difference. As an example in which the air cell group is divided into a plurality of systems that are performed with, the first system is divided into two systems, a first cell group and a second cell group in which air supply and discharge are performed at alternate timings. It is preferable to arrange the air cell belonging to the above section and the air cell belonging to the second section so as to be adjacent to each other.

With such a structure, since the parts holding the user's body are replaced in the vicinity, it is possible to maintain the comfort of use without making the user aware of changes in body pressure.

According to this structure, two supply / discharge pipes, which are connected to the air supply pump and have different supply / discharge timings, are provided in two directions along the edge of the seat. It becomes easy to communicate with each air cell.

Each air cell forming one air cell group may be communicatively connected to each other through a communication pipe, and this communication pipe is integrally molded by a mold similarly to each air cell. Also, the manufacturing process of the bed sore prevention mat is simplified, which is advantageous in terms of cost.

Further, in the floor slip prevention mat according to the present embodiment, the sheet materials having a large number of air cells of the lower openings formed of the molding material are juxtaposed with each other so that the openings overlap each other. You can

That is, the sheets formed into the same shape are superposed so that the air cells are independent from each other, and in the cell groups belonging to the same supply / discharge system, the communication pipes provided in the diagonal direction are used. In order to communicate with each other, the surroundings are welded by heat welding and sealing.

In such a structure, the same sheet material can be polymerized vertically and can be molded by one mold, and the manufacturing cost can be greatly reduced.

Further, as the bed sore prevention mat, the higher the height of the air cell is, the better the cushioning property is, and the difference between the expanded cell and the exhausted cell is increased to improve the bed sore prevention effect. In the embodiment, since the same sheet material is polymerized, the height of the air cell formed on one of the sheet materials is half, and the molding die is compact and easy to demold. The occurrence of defective products due to mistakes can be prevented as much as possible.

Further, if the communication pipe is formed in a cross shape, the upper and lower sheet materials can be the same ones molded in the same mold even if the mat shape is rectangular, and at this time, the mat-like shape can be obtained. Of the upper and lower communication pipes, the passages that are not communicated may be sealed by heat welding.

As described above, according to the present embodiment, it is possible to provide a bed sore prevention mat which is extremely low in cost, has a flexible air cell, and can quickly supply and discharge air.

[0033]

Embodiments of the floor slip prevention mat according to the present invention will be described below with reference to the drawings.

FIG. 3 shows a floor slip prevention mat A according to this embodiment.
FIG. 4 is a schematic explanatory view of the mat A, FIG. 5 is a plan view of the mat A, FIG. 6 is a partially enlarged perspective view of the mat A, and FIG. FIG. 8 is an explanatory view showing an expanded / contracted state, and FIG. 8 is an explanatory view showing a cross-sectional shape of an air cell of the mat A.

The basic function of the bed sore prevention mat A according to the present embodiment and the usage thereof are the same as those described in the description of the prior art (see FIG. 1). As shown in FIG. It is placed on B and used. M is a user.

The feature of this embodiment is that a large number of air cells 11 and 12 are arranged side by side in the plane direction and the air cell group 2 is formed.
And the air cell group 2 is divided into two systems in which air is supplied and discharged at alternate timings, and the air cells 11 belonging to the first system and the air cells belonging to the second system are divided.
In the floor slip prevention mat A in which 12 and 12 are arranged adjacent to each other, the air cells 11 and 12 are formed of a molding material (not shown) so that it is possible to shorten the air supply time for expansion and reduce the amount of mold collapse during exhaust. It has been reduced. In the present embodiment, the air cell group will be described by dividing it into two systems, but if it is divided into a plurality of systems in which air supply and discharge are performed with a predetermined timing difference, it is not limited to two systems. Absent.

In this embodiment, as shown in FIG. 3, FIG. 7 and FIG. 8, a sheet in which a plurality of downward-opening air cells 11 and 12 formed of a molding material made of a transparent synthetic resin material are juxtaposed. The materials 1 and 1 are abutted and connected so that the openings overlap each other.

That is, as shown in FIGS. 3 to 8, the floor slip prevention mat A according to this embodiment uses a molding material made of a synthetic resin in which the air cells 11 and 12 are arranged in a plane direction by a molding die (not shown). A plurality of sheet materials 1, 1 integrally molded in a row in four directions to form a sheet body 10, and an air cell group 2 formed by the plurality of air cells 11 and 12 is a first cell group. The second cell group 21 and the second cell group 22 are divided so that air is supplied and discharged between them at alternate timings. Moreover, the air cells 11 belonging to the first cell group 21 and the air cells 12 belonging to the second cell group 22 are arranged in a so-called zigzag pattern so as to be adjacent to each other (FIG. 4).

Then, the supply / exhaust pipe 3 is connected to the air supply pump P, and a flow path switching valve V is provided in the middle of the supply / exhaust pipe 3 so that the first supply / exhaust pipe is connected via the flow path switching valve V. 31
And the second supply / discharge pipe 32 are connected.

The flow path switching valve V is controlled by a control device (not shown) so as to switch the air supply flow path of air at a preset time of about 15 to 20 minutes, and the air supply pump P When the air supply port for communicating air is closed, the air in the air cells 11 and 12 is opened to the atmosphere so that the air can be exhausted.

The first supply / discharge pipe 31 and the second supply / discharge pipe 32 are connected to communication pipes 41, 42 for connecting the air cells 11, 12 of the cell groups 21, 22, respectively. The sheet body 10 is connected to the first and second supply / discharge passages 13 and 14 formed in the edge portion 10a of the sheet body 10. In this embodiment, the communication pipes 41 and 42 are
The air cells 11 and 12 are integrally molded with a mold.

The air cells 11 and 12 according to this embodiment are shown in FIGS.
As shown in FIG. 8, it is formed in a rectangular box shape and has side walls 11a and 12a, which respectively protrude upward and downward from the sheet body 10, on the periphery. Since the air cells 11 and 12 are rectangular box-shaped, the air cell group 2 has a lattice shape in which the air cells 11 and 12 are arranged in four directions on the sheet material 1, that is, a grid pattern (FIG. 5).

By thus forming the air cells 11 and 12 in a box shape, each of the air cells 11 and 12 has a firm waist, and when exhausted, it becomes a flat state in which it becomes substantially flat. , And as shown by arrow D in FIG.
It is possible to reduce the amount of shape loss as much as possible.

Further, since the air cells 11 and 12 have their waists and the side wall portions 11a and 12a are independently erected,
The air cells 11 and 12 do not fall down and overlap each other, and cleaning of dust and the like that tends to collect in the gap 23 between the air cells 11 and 12 becomes extremely easy.

Now, the operation of the bed sore prevention mat A having the above-mentioned structure will be described. As described above, the air cell 1
The air cell group 2 formed by 1, 12 is the first cell group 21
And the second cell group 22 are divided, and air is supplied and discharged between the both at alternate timings.

That is, when the air supply pump P is driven, air is first caused to flow through the one supply / discharge pipe 3 by the flow path switching valve V. For example, when first sending air to the first cell group 21,
The air flows into the first supply / discharge pipe 31, and further, as shown in FIG. 4, the first supply / discharge path 13 formed in the edge portion 10a of the sheet body 10.
Flow into the plurality of air cells 11 that are obliquely connected from each communication pipe 41 to expand the air cells 11 (see FIG. 7).

After a lapse of a predetermined time (15 to 20 minutes), the control device opens and closes the port of the flow passage switching valve V so that the air flows through the second supply / discharge pipe 32 to switch the flow passage.

That is, the air flows to the second supply / discharge path 14 formed on the edge 10a of the sheet body 10 on the side opposite to the first supply / discharge path 13, and a plurality of obliquely connected plural pipes are also provided from each communication pipe 42. Is sent to the air cell 12 to expand the air cell 12.

At the same time, in the flow path switching valve V, an open valve (not shown) formed in the flow path switching valve V is opened, and each air cell 11 in the first cell group 21 is pressed by the weight of the user M. In this case, the air cell 11 → the communication pipe 41 → the first supply / exhaust pipe 31 → the flow path switching valve V is made to flow and open to the atmosphere, and the air filled in the air cell 11 is quickly exhausted. I am trying.

At this time, the deformation amount of the air cell 11 pressed by the weight of the user M is extremely small as shown by the arrow D in FIG. 7, and when the air is refilled after the elapse of a predetermined time, the air filling amount. Air cell 11
The expansion is also done in a very short time. Since this similarly applies to the case of exhaust, the floor slip prevention mat A according to the present embodiment requires an extremely short time for expanding and contracting the air cells 11, 12.

Therefore, when the air cell 11 (12) holding the body of the user M is exhausted and deflated, the adjacent air cell 12 (11) is instantly inflated when the air is supplied. Therefore, the user M does not feel the vertical movement of the body and the like, and the user feels good. Moreover, since the air cell 11 of the first cell group 21 and the air cell 12 of the second cell group 22 are adjacent to each other, the air cell for holding the body of the user M is
The replacement of 11 and 12 will also be done in close proximity, and the user M will not be aware of changes in body pressure,
You can maintain good usability.

Here, the structure of the floor sore prevention mat A according to this embodiment will be described in more detail.

As described above, the mat A for preventing bedsores
Is a sheet material 1 which is a molded product and is polymer-welded in a state where the openings of the air cells 11 and 12 integrally formed with the sheet material 1 are brought into contact with each other. Use the same kind.

That is, as shown in FIG. 9A, the box-shaped air cells 11 and 12 are molded by a mold (not shown).
When the sheet members 1 and 1 of the same kind integrally formed with the communication pipes 41 and 42 having a substantially semi-cylindrical shape in cross section are butted against each other, as shown in FIG. 9 (b), the communication pipes 41 and 42 are attached to each other. The air cells 11 and 12 have a cross-shaped cross-like shape like a skirt.

As a result, the bedsore prevention mat A can be manufactured at low cost. Further, since the air cells 11 and 12 and the communication pipes 41 and 42 are integrally molded by the same mold, the manufacturing is facilitated and the manufacturing cost can be reduced.

If the sheet material 1 is formed in a square shape, when the two sheet materials 1 and 1 are vertically superposed, one of them may be rotated by 90 degrees to bring them into contact with each other, as shown in FIG. Since the communication pipes 41 and 42 are also aligned with each other and become the communication pipes 41 and 42 having a cylindrical shape in a sectional view in the overlapping state, the square sheet material 1 is used as a basic unit to connect them to form a rectangular floor slip prevention mat A. It may be configured.

Alternatively, instead of polymerizing sheet materials 1 of exactly the same kind, as another embodiment, as shown in FIG. 13 and FIG. 14, one sheet material 1 has a connecting pipe of a generally semi-cylindrical shape in cross section. 41, 42 are formed, but in the other sheet material 1, the communication pipes 41, 42 are omitted, and these are polymerized to form the sheet body 10.
Is formed. Again, in FIG. 13 (a), the convex mark indicates the surface of the sheet material 1, the tops of the air cells 11 and 12 are visible, and the concave mark indicates the rear face. The openings of the air cells 11 and 12 are visible.

By the way, in this embodiment, the two beds 1 and 1 in which a large number of square-shaped air cells 11 and 12 of the bed sore prevention mat A are integrally formed in a checkerboard shape as described above.
However, it may be modified as shown in FIGS. 16 to 22.

In the structure shown in FIG. 16, the air cells 11 and 12 having a rectangular shape as described above are integrally formed on only one of the sheet materials 1, and the other sheet material 1 is a flat sheet. Are joined together.

The one shown in FIG. 17 is obtained by forming a large number of air cells 11 and 12 integrally molded in the sheet material 1 into a hemispherical shape.
It is a polymer obtained by butting this up and down. Also, FIG.
As shown in FIG. 8, the air cells 11 and 12 having such a shape can be integrally formed on only one of the sheet materials 1, and the other sheet material 1 can be joined while the sheet is a flat sheet.

In FIG. 19, the air cells 11 and 12 are not rectangular but substantially rectangular (generally rectangular parallelepiped).
Note that, as shown in FIG. 20, the ridge line portion of the side wall portion rising from the sheet material 1 may be eliminated and the side wall portion may have a curved surface.

It should be noted that these are also shown in FIGS.
As shown in FIG. 2, the air cells 11 and 12 may be integrally formed on only one of the sheet materials 1, and the other sheet material 1 may be joined while the sheet is a flat sheet.

As described above, the floor slip prevention mat A according to this embodiment has the air cells 11 and 12 formed by the mold, and has the side walls 11a and 12a having the waist. Also, the shape is not easily lost even when exhausted, and since the original shape is maintained to some extent, air can be quickly supplied and discharged, and the comfort of the user M is not impaired. Moreover, the manufacturing cost can be reduced.

Further, since the sheet material 1 is made of a transparent material, for example, the condition of the skin of the user M can be observed from below the bed sore prevention mat A, which can be useful for prevention of bed sores and research of bed sores. it can.
