Description

[Detailed Description of the Invention] Technical Field This invention relates to an air mat that is effective in preventing bedsores that tend to occur during long-term medical treatment.

BACKGROUND ART The phenomenon of bedsores is a skin disorder caused by prolonged hospital bed life, which causes circulation disorders due to pressure on specific parts of the body, which is combined with softening of the skin due to sweating. Therefore, attempts have been made to prevent bedsores, such as by creating a bed in which the position of unevenness on the floor surface changes over time. However, these devices are not only complicated and expensive, but also provide unsatisfactory sleeping comfort even if they can achieve the effect of preventing bedsores.

Purpose The purpose of this invention is to reduce the thickness of the mat, improve the efficiency of air circulation within the mat, and ensure ventilation between the mat and the body to fully demonstrate the effect of preventing bedsores. Our goal is to provide an air mat that can.

Embodiments Examples of the present invention will be described below with reference to the drawings. In Figures 1 to 3, air mat 1
consists of a mat main body 2 and a connecting part 3. The mat main body 2 is made by directly and airtightly welding two sheets 4 and 5 made of synthetic resin, front and back, at their outer periphery 6 and a large number of lattice points 7 defined at a constant pitch using a high-frequency welder or the like. It is. A large number of small holes 8 are transparently provided in the front sheet 4 over the entire surface, and an air supply hole 9 is formed in one corner. Although the arrangement of the small holes 8 is irregular in the drawing, it may be regular.

A connecting portion 3, the cross section of which is shown in FIG. 3, is hermetically bonded to the upper surface around the air supply hole 9. That is, the connecting part 3 has a base 3a to be connected to an air supply source (not shown), and a flange-shaped base 3b at one end of the base 3a is fused to the front sheet 4 of the mat main body 2. There is. Therefore, in the air mat 1, an air passage 10 is formed between the front and back sheets 4 and 5, excluding the fused portion, with the connecting portion 3 serving as an inlet and a large number of small holes 8 serving as outlets.

In order to use the air mat 1 having the above configuration, the air mat 1 is placed on a bedsore-preventing bed whose surface unevenness changes over time as described above, a sheet is placed on the air mat 1, and the connection part 3 An air supply source (not shown) is connected to continuously supply air. The air mat 1 is inflated by the pressure of the air as shown in FIG. 2, and a very small amount of air flows out through the small holes 8. This air flow moves along the surface of the user's body, removes moisture caused by sweating, prevents the user's skin from softening, and creates a comfortable environment by constantly supplying fresh air at an appropriate temperature. .

Furthermore, since the air mat 1 has the front sheet 4 and the back sheet 5 directly bonded together at a large number of lattice points 7, its thickness is small even in the swollen state shown in FIG. 2. Therefore, even when used in combination with the bed described above, fluctuations in the unevenness of the bed surface are reliably conveyed to the user without being canceled out, thereby doubling the bedsore prevention effect of this bed. Furthermore, since this air mat is thin, even when used on a regular bed, the bed does not lose its characteristics and provides a good sleeping comfort. Furthermore, since the structure is simple, manufacturing is also extremely easy. Moreover, since the above-mentioned spot-like adhesion allows the air passages to extend vertically and horizontally, the efficiency of air circulation is improved, and each part of the body can be maintained at a substantially uniform temperature, making it possible to further improve the comfort of sleeping.

By the way, in the air mat 1 of this embodiment, the front sheet 4 of the mat main body 2 is provided with an air permeable surface layer 11 on its surface so as to cover the small holes. This surface layer 11 includes a base portion 11a in which a large number of fibers are arranged vertically and horizontally at intervals, and a large number of loop-shaped synthetic resin bristles 11b whose lower ends are attached to the base portion 11a are closely implanted. . In this way, even if no sheet is placed on the mat, the user's body will not come into direct contact with the surface of the front sheet 4 due to the presence of the hairs 11b. For this reason,
Numerous air flow paths are secured between the body and the air mat 1, and since the body or the sheets do not come into contact with the front sheet 4, the small holes 8 are not closed by the body, allowing for better air flow. Flow can be ensured around the body. Also,
Since the bristles 11b have a loop shape, the tips do not irritate the skin and have appropriate elasticity, making it comfortable. In this embodiment, particularly good air permeability can be ensured, so it is effective not only for preventing bedsores but also for relieving the discomfort of sleeping in the summer.

Note that in this example, loop-shaped bristles 11b were implanted in the base 11a as the surface layer 11;
The bristles are not limited to this, but may be ones with hook-shaped ends. Furthermore, surface layer 1
1 may be any material as long as it can ensure good air permeability; for example, it may be a simple woven fabric. Furthermore, any method may be used to implant the hair, such as ultrasonic welding or sewing a filament forming a loop to a large number of thin wires that are stretched across the length and breadth.

Effects As detailed above, according to this invention, the thickness of the mat is reduced, the air circulation efficiency within the mat is improved, and the ventilation between the mat and the body is ensured. The effect of preventing bedsores can be fully exhibited.
