Description

[Detailed Description of the Invention] Industrial Field of Use The present invention relates to an improvement in an air cushion that is partially installed and used to prevent pressure on affected areas such as bedsores and to prevent the occurrence of bedsores.

BACKGROUND ART As shown in FIGS. 10 and 11, an air cushion used for this type of application has a hollow air chamber 1 made of an elastically deformable material such as a plastic sheet or rubber. A substantially U-shaped bag-like main body 2 that can be inflated by filling the air chamber 1 with air is constructed. There is provided a structure in which a plurality of partition grooves 3 formed by joining are equally divided approximately radially (see Japanese Utility Model Application Publication No. 61-77020).

Problems that the invention aims to solve The conventional air cushion mentioned above has fulfilled the initial purpose of providing adequate support for affected areas such as bedsores when evaluating use in a ward. The following problems have arisen.

One of the problems is that the plurality of bulges 2a separated by the partition grooves 3 are bent up and down at the position of each partition groove 3, making it difficult to insert the tube into the patient's affected area. The patient had to be lifted while inserting the device into the affected area (mainly the lower back).

In addition, the patient's body pressure was concentrated at the joint of the partition groove 3, and there were problems with durability, such as the tendency for holes to form in the vicinity of the partition groove 3.

Furthermore, it was also found that the amount of air flowing through the partition grooves 3 between the respective bulges 2a was not so large, and the effect of preventing stuffiness was poor.

In view of the above-mentioned problems of conventional air cushions, the purpose of this invention is to provide an air cushion that improves these problems, enhances functionality, improves operability, and promotes air circulation. .

Means for Solving the Problems The present invention has a hollow air chamber made of an elastically deformable material such as a plastic sheet or rubber, and can be expanded by filling the air chamber with air. In an air cushion consisting of a bag-shaped main body, at least one or more partition grooves formed by joining the upper and lower surfaces are provided on the upper and lower surfaces of the bag-like main body and extend along the substantially U-shape. In this case, the bag-like body can be covered with a hygroscopic cover.

Function The air cushion of the present invention has a partition groove extending along the approximately U-shape of the bag-like main body.
The bulging portion partitioned by the partition groove also has a substantially U-shape, so that it does not bend up and down at the partition groove and can withstand insertion resistance into the patient. Therefore, 1
This makes it easier for a human caregiver to support the patient's body with one hand while inserting the air cushion with the other hand.

In addition, since the air moves smoothly to the affected area via the partition groove, the effect of preventing stuffiness is improved.

Embodiment FIG. 1 is a plan view showing an embodiment of the air cushion according to the present invention, and FIG. 2 is a -
Line sectional view, Figure 3 is a perspective view of the one in Figure 1, Figure 4 is a perspective view of the one in Figure 1.
The figure is a perspective view of the hygroscopic cover.

In FIGS. 1 to 3, 10 has a hollow air chamber 11 made of an elastically deformable material such as a plastic sheet or rubber, and an air valve 12 installed in a part of the air chamber 10 connects the air chamber 11. It is a roughly U-shaped bag-like body that can be expanded by filling with air. This bag-like main body 10 has a partition groove 13 extending along a substantially U-shape.
3 to form bulging portions 10a, 10a, air can freely enter and exit the affected area through the partition groove 13 between the bulging portions 10a, 10a, and the property of preventing stuffiness is improved.

The partition groove part 13 is constructed by joining the upper and lower surfaces, but at both ends of the substantially U-shape, the bulges 10a, 1
0a communicate with each other through communication portions 10b, 10b, and when the patient's body pressure acts, the air in that area is dispersed throughout and is not concentrated in one part. The communication part 1
0b may be located anywhere in the substantially U-shape.

The air valve 12 has a lid and a retractable structure, which is used in beach floats and the like.

As shown in FIG. 4, the hygroscopic cover 14 has a substantially circular bag shape capable of storing the bag-like main body 10, and has an inlet/outlet opening 15 formed on a part of the back side by slightly overlapping the edges of the opening. , Surface bonding type fasteners 16, 16, which are commercially available under the names of Velcro fasteners or Magic fasteners, are installed on the edge of this opening, and a part of the hygroscopic cover 14 has a bag-like main body. A positioning seam 17 is formed that fits into the approximately U-shaped opening of 10 and prevents movement of the bag-like main body 10.

Further, in the hygroscopic cover 14, the fabric 14a on the surface side that contacts the affected area of the patient has a surface layer made of a woven fabric made of a synthetic fiber such as polyamide, polyester, polyacrylonitrile, or a water-repellent fiber material such as wool fiber. This has a bonded structure with a backing layer made by polymerizing a textile fabric made of a fiber material with instant sweat absorption properties such as viscose rayon,
With the above structure, sweat and moisture generated by the patient are quickly absorbed into the textile fabric of the back layer, and the surface layer has a smooth feel. This allows for better insertion into the patient. Note that there are no particular restrictions on the fabric 14b on the back side of the hygroscopic cover 14. If the hygroscopic cover 14 is used in this way,
It is convenient for the user, provides good sliding during insertion, and can be disinfected and washed to remove dirt during use, so it can be kept clean.

FIG. 5 shows another embodiment in which two partition grooves 13, 13 are formed, and as shown in FIGS. 5 and 6, three bulges 10a, 10a, 10a are formed. .

FIG. 7 shows another embodiment in which bifurcated branches 13a are formed in a single partition groove 13 in a bilaterally symmetrical shape.

FIG. 8 shows another embodiment in which the overall shape of the bag-like main body 10 is a substantially equilateral triangular shape with an opening in a part, and FIG. This figure shows another embodiment having a substantially regular hexagonal shape.

In the present invention, the approximately U-shape of the bag-like main body 10 means a U-shape, a U-shape, a circle, an ellipse, a polygon larger than a triangle, etc., with a part missing and an opening. It is.

Effects of the invention According to the invention, since the partition groove has a substantially U-shape that is the same as the shape of the bag-like main body, the bending resistance is large and the insertion operation into the affected area of the patient can be facilitated. , one nurse can support the patient's body with one hand while inserting the air cushion into the patient's affected area with the other hand. Furthermore, when the patient's body pressure acts on the device, the air within the bulge partitioned by the partition groove moves quickly and is dispersed throughout the device, preventing pressure from concentrating on a portion of the device and causing damage.

Furthermore, since the partition groove is formed in a substantially U-shape and extends approximately the entire length of the bag-like main body, air in the affected area of the patient is ventilated from either the left or the right through the partition groove, thereby promoting prevention of stuffiness.

Further, by using a hygroscopic cover, the above-mentioned insertability and stuffiness prevention properties are further improved.
