[Detailed description of the device]

[0001]

This invention relates to a mattress device suitable for preventing pressure ulcers.

[0002]

2. Description of the Related Art For example, when a person sleeps on a bed, a mattress device is used to obtain a comfortable sleep. There are various types of mattress devices, one of which is formed by polymerizing a cushion body such as a spring unit with an elastic material such as urethane foam, and coating the polymer with a bag-like exterior material. is there.

When the mattress device having such a structure is used by, for example, a sick person or an elderly person who has to lie down for a long period of time, the heavy part of the user's body is continuously pressed by the repulsive force of the cushion body. The part may cause pressure sore (bed sore).

[0004] Pressure ulcers can often occur in areas of the body where the body continues to be compressed. However, if there is good ventilation between the body and the mattress device,
It is known that it is relatively hard to happen because the body is hard to get stuffy.

By the way, in the conventional mattress device, since the user's body is locally pressed as described above, it is often the case that the pressed portion is in close contact. for that reason,
For bedridden sick people and the elderly for a long period of time, there was a case where the close contact part of the body became stuffy and a pressure sore was likely to occur in that part.

[0006]

As described above, since the conventional mattress device has a structure in which the user's body is in close contact with the upper surface of the device and is apt to get damp, the mattress device must be supine for a long period of time. There were times when floor sores were likely to occur.

The present invention has been made based on the above circumstances, and its purpose is to prevent the body from being in close contact with the user when the user is supine and to allow the air to circulate well, so that the supine is maintained for a long period of time. Even if it does, it is to provide a mattress device that prevents the occurrence of floor slip.

[0008]

In order to solve the above problems, the present invention has an air chamber into which compressed air is supplied.
Flat air that - the mat, the air - air mat
Communication hole formed in the part other than the chamber in the thickness direction
When, the air - and polymerized on one surface of the mat three-dimensional mesh knit fabric, - an outlet hole compressed air which is formed on at least one surface of the upper and lower surfaces of the mat flows out, the air
A heating element polymerized on the other surface of the air-mat, the three-dimensional mesh knitted fabric, the air-mat and heat generation.
And a coupling means for integrally coupling the body .

[0009]

According to the above construction, the three-dimensional mesh knitted fabric is not only intimately attached to the user's body but also has good air permeability, and moreover, compressed air flows out from the air mat, so that the body becomes damp and the floor is slippery. Can be prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The mattress device shown in FIG. 1 is an air mat 1
Is equipped with. This air mat 1 has two sheets 1
By polymerizing a and partially adhering these sheets 1a, there are a large number of air chambers 2 formed by the non-adhered portions and communicating with each other, and a joint portion 3 formed by the adhered portions. It has no flat shape.

The air chamber 2 is designed to expand into a spherical shape by supplying compressed air. Two sheets 1a
On the upper and lower surfaces of the portions where the respective air chambers 2 are formed, very small outflow holes 4 are formed for outflowing a small amount of the compressed air supplied to the air chambers 2. That is, the compressed air flows out obliquely upward and downward from the respective outflow holes 4 formed on the upper surface and the lower surface of the air mat 1. That is, the outflow hole 4 is formed at a position off the top of the air chamber 2.

A communication hole 3a is formed in the joint portion 3 for communicating the upper surface side and the lower surface side of the air mat 1 with each other.
Further, a compressed air supply port 5 is formed on one end side of the air mat 1 as shown in FIG. An air pump 7 is connected to the supply port body 5 via a hose 6 as shown in FIG.
Compressed air is supplied to.

FIG. 1 showing one surface of the air mat 1
A sheet-shaped heating element 8 such as an electric blanket is provided on the upper surface of
The ceramic sheet 9 and the outer material 11 are sequentially polymerized. The heating element 8 is formed by embedding a heating wire 8b in a flexible cloth 8a, and generates heat by energizing the heating wire 8b. The ceramic sheet 9 is formed by applying powdery ceramic to a cloth, and is heated by the heat of the heating element 8 to generate far infrared rays. The outer material 11 is made of wool fur (twisted fibers) that gives a warm and soft feel.

On the lower surface, which is the other surface of the air mat 1, synthetic cotton 12 and three-dimensional mesh fabric cloth 13 are sequentially polymerized. As shown in FIG. 4, the three-dimensional mesh woven cloth 13 has an upper surface mesh material 14 and a lower surface mesh material 1
5 and 5 are connected by a connecting thread 16 parallel to the thickness direction H of the fabric so as to be integrated with each other at an appropriate interval to form a three-dimensional three-dimensional structure in which a space 17 is formed between the mesh fabrics 14 and 15. ing.

The upper surface mesh material 14 is formed in a diamond-shaped loop-shaped mesh array, and the lower surface mesh material 15 is formed in a drape shape.

As shown in FIG. 5, the upper surface mesh material 14 and the lower surface mesh material 15 may be formed in a loop-shaped mesh array having a hexagonal shape, and the mesh shapes are not limited at all. By the way

The material for knitting the three-dimensional knitted fabric 13 is
Synthetic fibers such as polyester, polyamide, acrylic and aramid, natural fibers such as wool and silk, as well as glass fibers, carbon fibers and metal fibers may be knittable fibrous materials.

Fasteners 18 are provided on the peripheral edge of the outer material 11 and the peripheral edge of the three-dimensional mesh knitted fabric 13 as coupling means. When these fasteners 18 are engaged, the polymer of the heating element 8, the ceramic sheet 9, the outer material 11, the synthetic fiber 12, and the three-dimensional mesh knitted fabric 13 polymerized on the upper and lower surfaces of the air mat 1 are integrally bonded. It is like this.

According to the mattress device constructed as described above, when a sick person, an elderly person, or the like is in bed for a long period of time, the mattress device is used with the surface provided with the three-dimensional mesh knitted fabric 13 facing up. This three-dimensional mesh knitted fabric 13 is
Connecting yarn 1 for connecting the upper surface mesh material 14 and the lower surface mesh material 15
Since it has a three-layered three-dimensional structure connected by 6, the air permeability in the thickness direction is good, and since an appropriate gap is provided between the connecting yarns 16, it intersects with the thickness direction. Also has breathability in the direction.

That is, since the three-dimensional mesh knitted fabric 13 has good air permeability over the entire surface, it prevents the user's body from getting stuffy and the temperature from rising, and prevents the user's body from getting a floor slip. be able to.

Moreover, the compressed air supplied to the air chamber 2 of the air mat 1 flows out from the outflow holes 4 and flows through the three-dimensional mesh knitted fabric 13 in the thickness direction and the direction intersecting the thickness direction. Therefore, the portion of the user's body that comes into contact with the three-dimensional mesh knitted fabric 13 is prevented from being covered with moisture and the skin is dried, which also effectively prevents pressure ulcers.

Further, since the air outflow hole 4 formed in the air mat 1 is formed at a position off the top of the air chamber 2, even if the air mat 1 is compressed by the load of the user, The outflow hole 4 is not crushed and blocked. Therefore, it is possible to always maintain a good outflow state of air from the outflow hole 4.

Further, since the three-dimensional mesh woven fabric 13 has good air permeability, by using it with its surface facing up,
It can be used cool in the summer. Further, when the three-dimensional mesh woven fabric 13 is used up, when the heating element 8 is energized, the air flowing out from the outflow hole 4 of the air-mat 1 is warmed by the heating element 8 and passes through the communication hole 3a. Since it circulates, not only the heating effect is obtained by the hot air, but also the user is warmed from the inside of the body by the far infrared rays generated by heating the ceramic sheet 9. In other words, it can be used warm in winter.

On the other hand, if the mattress device is used with the outer material 11 facing upward, it can be used comfortably due to the warmth and softness of the outer material 11, and in that state, the heating element 8 is energized to energize the ceramic sheet. When 9 is warmed, the heating effect can be further enhanced by the far infrared rays generated from the ceramic sheet 9.

The present invention is not limited to the above embodiment. For example, although the fastener was used as the connecting means in the above-mentioned one embodiment, instead of the fastener, a polymer such as an air mat, an outer material, or a three-dimensional mesh woven fabric was formed by sewing a well-ventilated fabric into a bag shape. It may be housed in the exterior ground.

The outflow holes formed in the air mat are
It may be formed on only one of the upper and lower surfaces, for example, the surface on which the three-dimensional mesh woven fabric is polymerized.
