Description

[Detailed description of the invention] <Industrial application field> This invention relates to an air bag for a blood circulation promoter that is worn around the head, and compressed air is repeatedly supplied and exhausted to the bag inside the bag. , a bag that intermittently pressurizes the head to promote blood circulation.

<Prior art> Generally, all or part of the body is covered with an air bag, compressed air is fed into the bag to pressurize it, and then the compressed air is exhausted to release the pressurization, and this is done intermittently. Blood circulation improvers that repeatedly promote blood circulation and are used to treat or prevent diseases caused by disorders of blood circulation are generally known.

In the above-mentioned blood circulation improver, the conventional air bag used in the head is simply formed into a long and narrow bag by welding the periphery of two airtight sheets, and the bag is directly inserted into the bag. Compressed air was supplied to inflate it into a nearly circular cross-sectional shape, which was then wrapped around the head.

Therefore, if the bag itself is used for a long period of time, it may break, or if the bag is wrapped around the head and compressed air is supplied, its cross-sectional shape will become almost circular, so the contact area with the head will increase. This caused problems such as the button falling off the head.

<Purpose of the invention> The air bag for the blood circulation enhancer of this invention was created to solve the above-mentioned problems. It has a structure in which a cutout is formed and a pair of latches are provided at both ends, and the plurality of notches at both ends and the pair of latches allow for tightness to the head. The object of the present invention is to provide a bag for an improved blood circulation promoter.

<Example> Hereinafter, an example of this invention will be described based on FIGS. 1 to 3 of the accompanying drawings.

As shown in FIG. 1, the air bag 1 is made of two sheets stacked one on top of the other and sewn around the periphery to form an elongated air bag so as to be wrapped around the head. At both ends of this air bag 1, there are a plurality of (two in the illustration) notches a,
b, c, d, and these notches a, b,
Hook-and-loop fasteners 2 and 3 as hooks are provided at c and d. Further, inside the air bag 1, as shown in FIG. 2, a long bag body 4 which can be inflated freely is housed.

This bag body 4 is a bag body 4 which has the inner periphery of the air bag 1 wrapped around it in a roundabout shape, and has protrusions a' and b' formed so that it can be housed in the notches a and b of the bag 1. 6 is sealed, and a part (approximately the middle part) is provided with a compressed air supply/discharge hose or a pipe body 7 for connection with a valve body. This bag 4 is bag 1
The bag 4 is movable inside without being welded to the bag 1, and the bent portions of the bag 4 are also not welded.

Furthermore, the bag body 4 shown in FIG.
It has a shape with protrusions a″ and b″ so that it can be installed internally.

The bag body 4 as shown in FIGS. 2 and 3 is placed inside the air bag 1 shown in FIG. The air bag 1 is rolled up, and compressed air is repeatedly supplied and exhausted from the tube body 7 to the bag body, and the expansion and contraction of the air bag 1 repeatedly pressurizes and depressurizes the head, thereby promoting blood circulation.

<Effects of the invention> As described above, according to this invention, compressed air is supplied to and exhausted from the inner bag and the air bag wrapped around the head promotes blood circulation. A fork-shaped notch is provided at both ends, and a hook-and-loop fastener or other hook is provided in this notch, and a bag body is also placed inside the fork-shaped notch at one end. Therefore, even if compressed air is supplied to the bag body and the cross-sectional shape of the air bag becomes approximately circular, the notches at both ends and the hook-and-loop fastener provided therein can wrap and hold the air bag well around the head. The air bag is difficult to separate from the head during repeated supply and exhaust, and since the pipe body 7 for connection with the valve body is provided approximately in the middle of the bag body 4, compressed air instantly flows through the bag body 4. It is sent throughout.

Furthermore, since the shape of the air bag 1 is constricted toward the center, when it is wrapped around the head, it easily conforms to the curved surface of the head. In particular, in the present application, the hanging tool is formed into a forked shape, and one of the hanging tools 3 has a bag inside the forked shape, so when the air bag is wrapped around the head. The synergistic effect of these configurations ensures a secure fit over the entire circumference of the head.
