DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the contents of the present invention will be described in detail with reference to the drawings. FIG. 1 is a plan view of an example of a joint supporter of the present invention. 1 is an outer supporter, which is a substantially rectangular front and back surface 2
2 layers of rubber or soft elastic synthetic resin sheet, part 2
A plurality of independent air chambers 2a, 2b, 2 between the layers of sheets
have c. Each of the air chambers has an air inlet / outlet 3 provided with a suitable valve so that air can be press-fitted by a manual pump or the like and held. As the valve of the air inlet / outlet port 3, a well-known valve that is commonly used for air pillows, air mats, floating bags, etc. is appropriately used. The arrangement of the air chamber 2 can be appropriately changed depending on the use and purpose of the joint supporter. In order to adjust the bulge when air is press-fitted into the air chambers 2a and 2b having a large area, it is preferable to appropriately provide a linear joint portion 4 in which front and back sheets are linearly joined. A through hole 5 is provided in a central portion of the outer supporter 1 in a portion that abuts the outside of the joint.

Reference numeral 6 denotes an inner supporter, which is similar to the outer supporter 1 and is made of a substantially rectangular front and back two-layer rubber or soft elastic synthetic resin sheet, and a plurality of independent air chambers 2d are provided between the two layers. 2e, each air chamber having an air inlet / outlet 3 with a suitable valve. The air chambers 2d and 2e are provided with a linear joint portion 4 in which front and back sheets are linearly joined. It is preferable to provide the through hole 5 also in the central portion of the inner supporter 6, but it is not always necessary to provide the through hole 5 in the inner supporter 6.

An appropriate number of engaging pieces 7 are provided so as to project on both sides of the inner supporter 6, and each of the engaging pieces 7 has a large number of annular threads and hooks or mushrooms on a pair of cloth pieces. One piece of the pair of planar fastener pieces 8 formed by implanting the protrusions is fixed, and the other piece of the planar fastener piece 8 is fixed to the outer surface of the outer supporter 1. Further, a cloth capable of engaging with the flat fastener piece 8 fixed to the engaging piece 7 may be attached to the entire outer surface of the outer supporter 1.

It is desirable that elastic fabrics or the like made of elastic yarn or the like be laminated and adhered on both sides of the outer supporter 1 and the inner supporter 6, respectively, to reinforce the sheet and improve the touch. Further, it is preferable that a foamed polyurethane resin sheet or the like is adhered to the inner side surfaces of the outer supporter 1 and the inner supporter 6 which are in contact with the skin, and a cloth is laminated on the outer side thereof to be joined.

When both sides of the outer supporter 1 and the inner supporter 6 are covered with cloth or the like, an outer supporter outer bag 9 and an inner supporter outer bag 10 are made of cloth or the like as shown in FIG. 2, and the outer bag 9, An air bladder 11 having a plurality of air chambers 2 is inserted into the inner bag 10, and an engaging piece 7 is projected on one side of the inner supporter outer bag 10 or the outer supporter outer bag 9, and the flat piece fastener 8 is attached to the engaging piece 7. It is also possible to fix one piece of the flat fastener and the other piece of the flat fastener 8 to the outer surface of the outer supporter outer bag 9.

FIG. 3 shows an embodiment in which the outer supporter 1 and the inner supporter 6 are integrally combined to form a single sheet. In the case of this embodiment, the joint supporter is composed of two front and back rubber or soft elastic synthetic resin sheets, and a plurality of independent air chambers 2 are provided between the two layers. Each air chamber 2 has an air inlet / outlet 3 as in the embodiment of FIG. A plurality of engagement pieces 7 are projected on one side of the joint supporter, and a pair of flat fastener pieces 8 are fixed to the outside of the position along the opposite side of the joint supporter and the inside of the engagement piece 7, respectively. .

Also in the joint supporter shown in FIG. 3, as shown in FIG. 4, an air bag 11 having a plurality of air chambers 2 is inserted into an outer bag 12, and the outer bag 12 is engaged with an engaging piece 7. Alternatively, the flat fastener piece 8 may be fixed to the opposite side of the engaging piece 7 and the outer bag 12 by projecting.

The sheet material on both sides of the air chamber 2 of the joint supporter of the present invention may meet the same rubber or elastic synthetic resin sheet, but the outer sheet is more stretchable than the inner sheet. Is preferably used. As a result, when the air chamber 2 is pressurized and filled with air, the sheet on the side close to the skin has a small elongation and the sheet on the outer side greatly expands and swells, so that the entire joint supporter easily adheres to the skin.

[0018]

To use the joint supporter of the present invention, for example, when the joint supporter shown in FIG. 1 or 2 is attached to the knee joint, as shown in FIG. 5, the outer side (front side) of the knee joint is shown.
The outer supporter 1 so that the through hole 5 abuts the joint, the inner supporter 6 is applied to the inside (rear side) of the knee joint, and the engagement pieces 7 of the inner supporter 6 are attached to both sides of the knee joint. From above, the flat supporter piece 8 is tightly engaged with the outer supporter 1 and the outer supporter 1 and the inner supporter 6 are wound around the knee joint portion.

Thereafter, the air chambers 2a, 2b, 2c, 2d,
Air is injected into 2e up to an appropriate pressure. The press-fitted air is retained by a valve provided in the air inlet / outlet port 3,
Air can be discharged by operating the valve.
By adjusting the air pressure in each air chamber, the pressure applied to each part of the joint supporter is adjusted, and the joint is fixed by applying the necessary pressure to the necessary portion.

When the joint supporter of the present invention shown in FIG. 3 or 4 is attached to, for example, a knee joint, the joint supporter is wound from the rear side of the knee to the front side of both sides, and the joint supporter is attached to the front side of the knee joint. The joint piece 7 is placed on the opposite side of the joint supporter, and the flat fastener piece 8 is engaged. At this time, if the engaging piece 7 is mounted so that it does not hang on the joint portion,
As shown in, the outside of the joint is exposed and the knee joint can be slightly bent.

The joint supporter of the present invention can be used not only for knee joints but also for elbow joints and ankle joints.

[0022]

According to the joint supporter of the present invention, a plurality of independent air chambers can be filled with air at different pressures, respectively, so that necessary portions of the joint can be fixed with a required force. Further, it is possible to allow the joint to move within a certain range, enhance the effect of treating a fracture or sprain of the joint, and prevent the joint from sticking during treatment.

The joint supporter of the present invention is flexible, comfortable to wear, comfortable to wear, and has an effect of keeping heat in the air chamber. Further, the joint supporter of the present invention is not bulky during storage, and the same supporter can be appropriately adjusted and used for patients with various symptoms.
