[0007]

BEST MODE FOR CARRYING OUT THE INVENTION An airbag type splint device according to the present invention has an airbag body which can be filled with air or an inert gas other than air, and has an upper limb or an upper limb for fixing an affected part. It is common to conventional ones in that it is used by wrapping around the lower limbs and the like.

[0008] As the gas to be filled, most simply, air capable of inhaling expiration as well as inflating a so-called vinyl floating ring can be used. In addition, a pump may be used instead of exhalation. In addition to the air, an inert gas packed in a gas cylinder or the like can be used, and particularly, carbon dioxide gas, nitrogen gas, and the like are preferable.

The main body is formed of a sheet material made of a resin having good gas barrier properties, since it is necessary to form the main body and maintain a required internal pressure for a long time. In this case, various synthetic resins besides natural and artificial rubbers correspond to the resin. Among general-purpose resins, flexible and stretchable resins such as vinyl chloride resin, polyethylene and other polyolefin-based resins, polyamide resins such as various nylons, and fluorine resins can be used. Rubber, synthetic rubber, silicon rubber, fluorine rubber and the like can be used.

[0010] The sheet material constituting the main body does not have to be a single layer, but may have a laminated or multi-layered structure from the viewpoint of durability or leakage resistance. Furthermore, as in the case of a splint device for the lower limb, it is necessary to bear the load of the lower limb occupying a considerable part of the body, and in some cases, it is necessary to withstand the concentration of the load in lifting or walking, etc. In addition, the use of a reinforcing sheet material in combination with the lower limbs, particularly the feet, can prevent breakage. However, since the X-ray transmission inspection can be performed while the splint device is worn, it is not preferable to apply a metal material or a composite structure that greatly hinders the transmission of X-rays.

[0011] Such a main body is composed of a plurality of air chambers communicating with each other. Here, the air chamber means a portion which can be filled with gas and inflated, and can be in a flat state if gas is released. The airbag body and its air chamber are formed by bonding important parts of the sheet material. The bonding includes bonding in a narrow sense using an adhesive, fusion by heating or welding by a solvent, and a combination thereof.

The aerator body has at least one air inlet. The air inlet may be an air inlet plug with an integral plug or a valve with a valve, or may be only an air inlet with a lid or plug to stop the mouth later. Since the air chambers of the main body communicate with each other, at least one air inlet is sufficient, but a plurality of air inlets can be used at the same time.

Various known means and methods can be used for attaching the main body of the aerator so as to enclose the upper limb or the lower limb. It is desirable that the shape should be kept substantially cylindrical so as to be wrapped, and should not prevent clearing the flat shape when not in use. A slide fastener, a hook, or the like is suitable for the attachment means satisfying such conditions. However, a method may be used in which a string passing hole is provided in the marginal portion of the main body and tightened with a string.

By the way, it is necessary that the main body has an air chamber having a structure suitable for enclosing the upper limb or the lower limb.
For a structure suitable for wrapping, it can be stated that it is desirable first that the number of air chambers is at least three or more. On the other hand, the greater the number of air chambers, that is, the more subdivided the air chambers, the higher the pressure of air or other gas to be filled, and the higher the compression strength on the affected area. It will also be. in this case,
Durability also improves. However, even if it is too finely divided and the pressure of the gas to be filled is too high, the fixing effect of the splint is weakened. For this reason, in a lower limb-like splint device, the number of air chambers of 3 to 10 is appropriate, and the range of 4 to 6 is preferable.

In the splint device of the present invention, when exerting the effect as a compression bandage, if the pressure of the filling gas is too high, the blood vessel will be excessively compressed, and the blood flow will be obstructed. Conversely, if the pressure of the gas is too low, the intended fixation of the affected area and the hemostatic effect of the skin surface layer cannot be obtained.
The affected part compression pressure for which the effect has been confirmed is several tens Pa / m ² ~
The range is more than 10 Pa / m ² , preferably 100
The range is from Pa / m ^{2 to} 10 KPa / m ² .

In order to make the splint device of the present invention easier to use, an elongated air chamber is formed in the longitudinal direction of the upper limb, the lower limb and the torso, that is, substantially in the vertical direction of the body. desirable. However, the affected part may be fixed so that the air chamber part related to the hand, the toe and the neck part is wrapped by one air chamber part. For this reason, it is preferable to prepare a dedicated splint device having a shape and structure suitable for the shape of the affected part.

Means for inflating the main body include inhalation of expiration, injection of gas filled in a gas container, and injection of air by a pump. When a gas container is used, its internal volume and internal pressure are determined by the internal volume of the main body and the compression pressure of the affected part. When a gas container is used, a gas container having a capacity of several tens of milliliters for disposable use and a gas container containing more than ten liters called a gas cylinder can be appropriately used. The filling pressure range can therefore be used from several hundred KPa / m ² to several tens MPa / m ² , which is used under reduced pressure from several tens KPa / m ² to several hundred Pa / m ² .
