[Detailed description of the device]

[0001]

[Industrial field of use] The present invention relates to a device for preventing finger contracture used for patients with aftereffects of stroke.

[0002]

2. Description of the Related Art It is well known that muscle contracture develops in many patients with sequelae of stroke, and as a preventive measure, it is effective to maintain flexibility by stretching and contracting the muscles. Relatedly, it is widely recognized that long duration of the palmar refraction state in a patient's sleep hinders the prevention and amelioration of muscle contracture.

As a conventional means for keeping the palm of the hand in a stretched state, the palm and arm of the patient's hand are brought into contact with a plate-like body and a bandage is wrapped around it to suppress the refraction of the palm of the hand. To do.

[0004] By the way, in the treatment of fractures of the quadrum, etc., a Gibbs bandage is used to hold the fractured part in the correct position. This is useful when holding the correct position for a long time. It is not applicable to the application that is detached each time awakening.

[0005]

SUMMARY OF THE INVENTION The conventional means for keeping the palm of the hand in a stretched state has a problem that it takes a lot of time to wrap the bandage and to prevent the bandage from being entangled when it is not used. There is.

Further, there is a problem in that the bandages that are usually used lack elasticity, so that the palms of the fingers are constrained and the sense of discomfort is strongly felt.

The present invention has been made in view of the above problems of the conventional method, and an object of the present invention is to attach a device when a patient shifts to sleep and shift to a muscle stretching exercise after awakening. An object of the present invention is to provide a finger contracture prevention device that facilitates the removal of the device when the device is in use, is easy to handle when the device is not in use, and has no discomfort to the attached device.

[0008]

The present invention has been made to solve the above problems, and when a plate made of a hygroscopic material is brought into contact with the plate by extending the palm and forearm of the hand. The palm and forearm of the hand in which the plate body is formed in a shape including a portion in which the palm of the hand and a part of the forearm are in contact with each other, and a plurality of strip-shaped elastic bodies are abutted on the plate body Are attached so as to be pressed toward the plate body, and all or a part of the plurality of band-like elastic bodies are provided with the band-like elastic bodies that are paired therewith or the engaging portions that are engaged / separated from the edge of the plate body. It is provided.

It is preferable that the engaging portion is made of a velcro (trade name).

Further, although the band-shaped elastic body is made of a rubber cord in the embodiment described later, this is a spring formed in a band shape, and a sweat absorbing material such as cloth is provided on the side surface of the spring, and the spring is You may make it hook with a moderate elasticity with the hook provided in the side edge part of a board.

Further, it is preferable that the strip-shaped elastic body is attached at a position aligned with each of the knuckle portion of the hand which is in contact with the plate body and the wrist portion of the forearm.

Further, the plate made of the hygroscopic material is
In the examples described later, wood is covered with a cloth, but this may be made of a porous hard synthetic resin material or a non-porous hard synthetic resin material covered with a sweat absorbing material such as cloth.

[0013]

When the palm of the hand is placed on the plate surface and the band-shaped elastic body is attached to the outside of the palm, the palm extends along the plate.

Further, when the strip-shaped elastic body provided near the tip of the plate is pulled and moved to the opposite side surface of the plate by raising the tip of the plate, it is stretched on the opposite side of the plate.

Further, the strip-shaped elastic body provided with the engaging portion is mounted on the opposite side of the plate body when the engaging portion is engaged on the opposite side of the plate body.

Further, the plate made of the hygroscopic material absorbs the sweat generated by the palm of the finger.

[0017]

1 is a perspective view showing an embodiment of the present invention, FIG.
FIG. 2 is a vertical sectional view taken along the line II-II in FIG. In this figure, reference numeral 1 designates a plate, which is formed by stacking two pieces of wood 1a covered with a cloth 1b. 2a and 2b are band-shaped elastic bodies, which are known as rubber cords, and are thin woven fabrics woven into a shrinkable woven fabric. The strip-shaped rubber cords 2a and 2b are sandwiched between two pieces of wood 1a and 1a. The band-shaped rubber cord shown by 2b is provided with an overlapping portion in the middle thereof, and a hooking portion 3 made of a velcro for enabling the joining / separation of the overlapping portion.

Next, the operation of this embodiment will be described. When the palm of the patient is extended and brought into contact with the surface of the plate 1 and a band-shaped rubber cord is stretched outside the palm, the palm extends along the plane of the plate 1. The band-shaped rubber cord 2a not provided with the engaging portion 3 is
When it is pulled by the fingertip so as to be separated from the plate body 1, a fingertip insertion space for the patient is formed therein. The sweat generated by the patient's palm is absorbed by the cloth 1b of the plate 1 and the wood 1a.

A strip-shaped comb string 2a provided near the tip of the plate body
Is pulled and moved over the tip of the plate 1 to the opposite side of the plate to be stretched on the opposite side of the plate. The strip-shaped rubber string 2b provided with the engaging portion 3 is attached to the opposite side surface of the plate body when the engaging portion is engaged with the opposite side surface of the plate body 1. The state is shown by a chain line in FIG.

[0020]

As described above, since the device for preventing finger contracture according to the present invention has the above-mentioned structure, the device can be attached / detached to / from the palm of the patient's finger very easily.

Since the belt-shaped elastic body can be arbitrarily attached to either side of the plate body, the tool can be attached to both the left and right fingers and palms. Therefore, it is possible to save the trouble of selecting the right hand or the left hand.

Further, the means for pressing the palm of the patient against the plate is made of an elastic body which adapts to the movement of the palm, and the engaging position of the engaging portion is continuously adjustable so that the palm can be adjusted. The pressure applied is set to an appropriate level,
Combined with the fact that the plate is made of hygroscopic material, there is almost no discomfort when wearing this device.

Further, since the means for pressing the palm of the hand against the plate body is a band-shaped elastic body formed to be relatively short, it does not become tangled when not in use.
