Description

  The present invention relates to a rehabilitation device for assisting the recovery of the motor function of a finger for a patient whose paralysis disorder remains in the hand due to cerebral infarction or the like.

  When suffering from cerebral infarction or the like, a paralysis disorder may remain in the fingers of the hand. As the rehabilitation means in this case, the finger's motor function is gradually recovered by repeatedly bending and stretching the fingers.

  However, in such a case, a bending force can be applied, but extension is hardly possible. For this reason, after bending, it must be stretched by a caregiver.

  As a conventional rehabilitation device for fingers for such a paralysis disorder, as shown in Japanese Patent Application Laid-Open No. 8-168503, a device that fits in the range of the forearm to the interphalangeal joint is used. In addition, a device that forcibly and gradually extends a paralyzed finger is disclosed.

  Japanese Patent Application Laid-Open No. 10-33604 discloses a glove body in which a balloon body that becomes a plane when inflated is incorporated, and a finger that has been deflated by air pressure is gently extended.

  However, the rehabilitation device as described above is not a device for bending and stretching, but a device for forcibly extending a finger that remains bent due to paralysis.

A conventional rehabilitation device for hand movement has been used after a finger has moved to some extent.
For this reason, there is no device for assisting finger movement until a force is applied to the finger from a state where the finger hardly moves (a state where the finger moves about 1 mm) to a state where the finger moves to a certain degree (a state where the finger moves about 5 mm). It was.

  The wrist fixing tool 2 is composed of a base 2a on which a wrist is placed and a belt 2b for fixing the hand. The base 2a is easy to fix and easy to operate when the wrist is placed on the wrist 2a. Thus, the surface should have elasticity, for example, rubber or sponge may be attached. The belt 2b is preferably fixed by a hook type or a hook-and-loop fastener that can be easily fixed and removed.

  When the wrist is fixed by the wrist fixing tool 2, the tension members 3a to 3f are provided with fixing portions 3a1 to 3f1 at positions extending in the extending direction corresponding to the fingers, and the fixing portions 3a1 to 3f1 Rubber strings 3a2 to 3f2 having a strong tensile force are attached, and rubber rings 3a3 to 3f3 are provided at the front end portions of the rubber cords 3a2 to 3f3 for fitting with the fingers.

  Instead of the rubber cords 3a2 to 3f2, a coil spring, an elastic resin cord material, a rubber belt, or the like may be used, and any one having a strong tensile force may be used. The rubber rings 3a3 to 3f3 that fit on the finger may be any ones that can be fixed to the finger, and may be a fastener using a hook-and-loop fastener or a hook, a resin ring, or the like.

  When the right hand is fixed to the wrist fixture 2, 3a corresponds to the thumb, 3b corresponds to the index finger, 3c corresponds to the middle finger, 3d corresponds to the ring finger, and 3e corresponds to the little finger.

  When the left hand is fixed to the wrist fixture 2, 3f corresponds to the thumb, 3e corresponds to the index finger, 3d corresponds to the middle finger, 3c corresponds to the ring finger, and 3b corresponds to the little finger.

  In this way, both right and left hands can be handled.

  The stimulating member 4 may be any ball shape having a large number of protrusions on the surface. When the wrist is fixed to the wrist fixing device 2, the ball body is positioned at the palm portion, and the palm is relocated during the rehabilitation operation. Anything that can stimulate can be used. A rubber hollow ball may be provided with a large number of rubber protrusions.

  The ball-like stimulating member 4 is embedded with bolts, and is attached to the base 1 with a nut from the bottom, and the height can be adjusted by adjusting the nut.

The fixing portion is provided with an adjusting screw 11 that can move the position of the fixing portion of the rubber cord back and forth, and adjusts the tensile force to be increased or decreased depending on the symptoms of the user.

  In this way, the right hand is attached, and each finger is bent by the patient's own force. Of course, it cannot be bent enough. However, if you can put your own force on the finger and thereby pull the rubber string as much as possible, it will be pulled back to its original state when the force is removed. Use your fingers again. By repeating this action, you can train yourself to apply strength to your fingers and gradually bend your fingers.

  In the conventional finger rehabilitation, the assistance of a third person is required. In other words, it was necessary to bend the finger with force and to have the third person extend the finger to the original state when the force was released.

  The finger rehabilitation device of the present invention is for performing bending and stretching exercises by itself, and is not a device for forcibly extending a finger that remains bent due to paralysis.

  A conventional rehabilitation device for hand movement is a device to be used after a finger moves to some extent.

  The finger rehabilitation device of the present invention is a finger movement until a force is applied to a finger from a state where the finger hardly moves (a state where the finger moves about 1 mm) to a state where the finger moves to a certain degree (a state where the finger moves about 5 mm). This is a finger rehabilitation device that enables even one person to rehabilitate.

  As described above, the finger rehabilitation device according to the present invention has been conventionally trained by one person at any time without requiring the assistance of a third party even when training to move a finger slightly in the initial stage of rehabilitation. Therefore, recovery is fast, and rehabilitation according to one's symptoms can be planned and performed freely.
