【Example】

 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 the joint supporter of the present invention. Reference numeral 1 denotes an outer supporter, which is composed of a substantially rectangular front and back two-layer rubber or soft elastic synthetic resin sheet, and has a plurality of independent air chambers 2a, 2b, 2c between the two-layer sheets. Each air chamber has an air inlet / outlet port 3 equipped with an appropriate 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 commonly used for air pillows, air mats, floating bags, etc. may be used as appropriate. 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 1 and 2b having a large area, it is preferable to appropriately provide a linear joint portion 4 in which the front and back sheets are linearly joined. A through hole 5 is provided in the central portion of the outer supporter 1 in a portion that comes into contact with the outer side of the joint.

Reference numeral 6 denotes an inner supporter, which, like the outer supporter 1, is made up of two substantially rectangular front and back rubber or soft elastic synthetic resin sheets, and a plurality of independent air chambers 2d are provided between the two layers. 2e, each air chamber has 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 the 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 having the projections attached thereto 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 a stretchable cloth or the like made of elastic yarn or the like be laminated and adhered on both surfaces of the outer supporter 1 and the inner supporter 6 to reinforce the sheet and to improve the feel. Further, it is preferable that a foamed polyurethane resin sheet or the like is attached to the inner side surfaces of the outer supporter 1 and the inner supporter 6 which come into contact with the skin, and a cloth is laminated on the outer side thereof to be joined.

When both surfaces of the outer supporter 1 and the inner supporter 6 are covered with a cloth or the like, an outer supporter outer bag 9 and an inner supporter outer bag 10 are made of a cloth or the like as shown in FIG. 2, and the outer bag 9, An air bag 11 having a plurality of air chambers 2 is inserted into the inside 10, and an engaging piece 7 is projected from one side of the inner supporter outer bag 10 or the outer supporter outer bag 9, and the flat 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 joined to form a single sheet. In the case of this embodiment, the joint supporter comprises 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 of the sheets. 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 fasteners 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 case of the joint supporter shown in FIG. 3, as shown in FIG. 4, the air bag 11 having the plurality of air chambers 2 is inserted into the outer bag 12, and the engaging piece 7 is inserted into the outer bag 12. Alternatively, the flat fastener piece 8 can be fixed to the opposite side of the engaging piece 7 and the outer bag 12 by projecting.

The sheet materials 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. It is preferable to use a sheet. 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 joint supporter as a whole easily adheres to the skin.

[0018]

[Action]

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

After that, air is injected into each of the air chambers 2a, 2b, 2c, 2d, and 2e up to an appropriate pressure. The press-fitted air is held by a valve provided at the air inlet / outlet port 3, and the 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 parts.

When the joint supporter of the present invention shown in FIG. 3 or 4 is attached to, for example, the knee joint, the joint supporter is wound from the rear side of the knee to the front side through both sides, and the joint supporter is attached at 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, the outside of the joint is exposed as shown in FIG. 2, 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, ankle joints, and the like.

[0022]

[Effect of device]

 According to the joint supporter of the present invention, it is possible to fix a necessary portion of the joint portion with a required force by filling the plurality of independent air chambers with air at different pressures. It is possible to allow movement within a range, enhance the effect of treatment of fractures and sprains of joints, and prevent the fixation of joints during treatment.

The joint supporter of the present invention is flexible, comfortable to wear, comfortable to wear, and has a warming effect due to 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.
