Description

The present invention relates to central nervous system diseases and disorders such as cerebrovascular disorder, cerebral trauma, cerebral palsy, and spinal cord injury, as well as peripheral neuropathy, joint and muscle disorders. The present invention relates to a function improving device for a finger or the like for improving the function of the arm joint, the hand, or the finger with respect to the accompanying functional disorder of the arm joint, the hand, or the finger.

(Prior Art) Due to the above-mentioned diseases and disorders, forearms, arm joints, hands,
When a hand dysfunction occurs, it is necessary to perform training to restore motor function concurrently with treatment, but it is extremely difficult to recover the dysfunction of the arm joint, hand, and finger since ancient times. Therefore, in recent rehabilitation medicine, in spite of a lot of research being conducted, a satisfactory function improver has not yet been developed. For example, when trying to extend the arm joints, hands, and fingers that have flexion contracture or extension disorders by the action of air pressure or spring, there are many cases where movement is complicated and an extra burden is placed on the patient, and satisfactory results are obtained. Has not been done.

Here, the applicant of the present application disclosed a new invention by Japanese Patent Application No. 58-192254. In the present invention, the palm-cover cloth in the shape of the fingers is expanded and the fingers are expanded. Fingers attached to the palm pad in order to individually fasten it to the palm pad in the state, and the fingers attached to the palm pad, which are arranged between the finger rests except the thumb and the index finger. A function improving device comprising an interstitial air sacs and a plurality of air sacs for extension attached to the opposite surface of the palm pad to extend the fingers, hands, and wrist joints, wherein compressed air is applied to each of the air sacs. Supply
After elapse of the required time, it is possible to cause flexion contracture and extension disorder of the patient by rhythmically and intermittently performing the extension of the wrist joint with the dysfunction and the extension movement of the hand and fingers by repeating the exhaustion. It improves and creates factors that induce automatic movement.

Thus, unlike the conventional glove-type function improver, this functional improvement is based on a flat palm hand cloth as the base fabric without making the main body into a glove shape, and a finger stopper for individually fixing the five fingers is provided. , It makes it easy to attach flexed and contracted fingers, and by providing a web-shaped air bag for expanding the fingers between the fingers, the fingers and the like can be expanded by expanding the fingers at the same time as extending the fingers. It has an epoch-making effect in improving the function of and is well received by the medical community.

However, the inventor is not very satisfied with that, the ability to bend the wrist joint back to the back side is insufficient, the flow rate of the compressed air cannot be changed with the fingers, and the compressed air is supplied while the compressed air is being supplied. We paid attention to the fact that we cannot separate the source and the patient.

(Problems to be Solved by the Invention) In the present invention, the invention according to Japanese Patent Laid-Open No. 192254/58 does not have a sufficient function of bending the wrist joint back to the back side. The problem was to solve the problem that the flow rate could not be changed and that the compressed air supply source could not be separated from the patient while the compressed air was still being supplied, and it has functions that could not be achieved by the conventional invention. Therefore, it is possible to more effectively induce automatic movement and to increase the practical value.

(Means for Solving Problems) In order to solve the above-mentioned problems, the present invention supplies and exhausts compressed air to a function-improved portion for expanding fingers and extending hands, wrists, arms, and the like. In a function improver such as a finger in which a function improver body composed of one or more air sacs for expanding and contracting and a compressed air source are connected by an air supply / exhaust hose, the position of the air supply / exhaust hose near the improver body , A pipe joint comprising a socket and a plug is provided, a valve for closing the flow path is built in the socket or the plug on the main body of the improver, and a flow control mechanism is provided in the socket or the plug. A specific example is as follows. A flat palm pad formed in a shape and size that completely covers the palm with the fingers spread, and along the inner arm surface of the wrist and forearm extending to the base of the palm pad portion. A base cloth composed of a flat forearm cloth portion formed in a shape and a size is formed of a flexible material, and the thumb side (first finger) and the index finger (second finger) are formed on the palm side of the base cloth.

(Operation) Next, the operation of the present invention will be described.

The function improving main body of the present invention is attached to a function improving portion such as a hand, a wrist, or an arm. When compressed air is supplied to the one or more air sacs formed in the function improver from an air supply / exhaust source via an air supply / exhaust hose, the air sacs expand and are closely fixed to the function improver body. Forcibly expand and extend the air sac improving parts such as wrists and arms. In this case, the content of the improvement exercise is determined by the number of air sacs and the mounting position.

Further, a valve for closing a flow passage built in a socket or a plug of a pipe joint formed of a socket and a plug provided in the vicinity of the improver body of the air supply / exhaust hose is automatically provided at the moment when the pipe joint is separated. Block the flow path. Therefore, if the pipe joint is separated while the air bag is inflated, the inflated state is maintained.

Such forced supply and forced exhaust of compressed air can be easily performed by the adjusting mechanism provided on the hand supply / exhaust hose, and can also be performed by the patient himself if he gets used to it. Further, the flow rate adjusting mechanism provided in the pipe joint or the like can adjust the flow rate of supply / exhaust from, for example, 0 to fully open, so that the time required for supplying compressed air to expand the air sac, and vice versa It can be adjusted freely and can be slow or fast depending on the degree of the patient.

After the required time has passed for the extension / expansion state, the air is evacuated again. Normally, the extension / expansion movements of fingers, wrists, etc. are periodically performed for a certain period of time, and the above-mentioned movements are repeated 10 times or more.
Repeat 0 times. In addition, sometimes, the pressurizing time is not continuously set, and the pressurizing is continuously performed for a relatively long time. When the patient becomes accustomed to this exercise, the number of times is increased, and the time for one extension and expansion is increased.

Furthermore, when it is desired to move or perform other exercises while maintaining the supply state of compressed air, that is, the swelling state of the air sac due to the necessity of examination by combining other exercises according to the rehabilitation menu, two air supply / exhaust If the pipe joint connecting the hose is operated with one touch to separate the hose, the opening / closing mechanism of the flow path will be automatically closed. Therefore, move while maintaining the compressed air supplied. You can

In the meantime, the patient can move his / her fingers and wrists in his / her own opinion (induction of automatic movement), and eventually the paralyzed function is revived.

After the treatment, finger stops 16a to 16e and arm stops 22a,
Remove 22b from the hand by opening the velvet fastener.

Next, the operation of the pipe joint in the above embodiment will be described.

The pipe joints of the two examples shown in FIGS. 9 and 10, 11 and 12 each consist of a pair of plugs 85, 85a and sockets 75, 75a, and male parts of the plugs 85, 85a. When 97 is inserted into the insertion holes of the sockets 75, 75a, the locking ring 78 suspended and supported by the flexible tongue piece 76 projecting from the main tubular member of the sockets 75, 75a,
Since the tongue piece 76 has flexibility, it can move downward in the drawing, and the locking piece 80 of the locking ring 78 is the male piece 97.
The locking piece 80 of the locking ring 78, which has been moved downward once, is allowed to enter the locking groove 8 formed on the outer peripheral surface of the male piece of the plug 85.
6 and the plug and socket are coupled and locked together as shown in FIG. Also, the locking groove 8 of the plug 85
When the pressing piece 99 formed on the locking ring 78 that engages 6 is pressed in the direction of bending the tongue piece 76 against the elastic force of the tongue piece 76, the locking piece 80 and the locking groove 86 are separated from each other. When the engagement state is released, the male piece 97 can be easily pulled out to separate the plug and the socket.

Next, the case of adjusting the flow rate with the flow rate adjusting mechanism at the hand position will be described. In the pipe joint shown in FIGS. 9 and 10, when the rotary cylinder 77 is rotated clockwise from the socket opening end side, The pin 82 moves to the socket opening side along the spiral guide groove 81, and the pipe 79 and the valve push pipe 84 move to the right in the figure with the movement of the pin 82. Also,
When the rotary cylinder 77 is rotated counterclockwise from the forward position, the guide pin 82 returns to its original position, and the pipe 79 and the valve push pipe 84 also retract. The sliding valve 83 provided on the plug 85 normally closes the flow path by the elastic force of the spring 87, but in the state where the socket 75 and the plug 85 are connected, the rotary valve 77 on the socket 75 side is rotated clockwise. When the push valve tube 84 is advanced to the right in the figure by turning to the right, the flow path tube 9
8 pushes the slide valve 83 against the slide valve 83, and the slide valve 8
3 slides to open the fluid passage. The larger the degree of turning of the rotary cylinder 77, the more the valve push tube 84 moves forward to increase the opening of the sliding valve 83 to allow more fluid to flow, and conversely, the smaller the degree of turning, the smaller the opening of the sliding valve 83. In this way, the flow rate can be adjusted by adjusting the opening / closing degree of the slide valve 83 by operating the rotary cylinder 77.

Further, in the pipe joint shown in FIGS. 11 and 12, when the plug 85a and the socket 75a are integrally coupled and locked, the tubular body 98a having the slide valve 83a of the plug 85a in the push valve portion 79a of the socket 75. Of the spring 87a against the elastic force of the spring 87a, the sliding valve 83a integral therewith is separated from the valve seat, and the socket 75a
Through hole and the through hole of the plug 85a communicate with each other.

In this manner, when the rotary cylinder 77a on the plug 85a side is rotated with the socket 85a and the plug 75a connected, the front member 88 and the front member 88 connected to the tubular body along with the rotary cylinder 77a are moved. The locked flow rate adjusting disc 94 also rotates within a range in which the protrusion 96 of the flow rate adjusting disc 94 can move in the guide groove 92, and the rear defective material 90
At the rotation angle where the fan-shaped hole 91 of No. 3 and the fan-shaped hole 95 of the flow rate adjusting disc 94 coincide with each other, the opening amount of the flow hole becomes maximum, and the fan-shaped hole 95 of the flow rate adjusting disk 94 causes the fan-shaped hole 95 of the flow rate adjusting disc 94 to be formed. It becomes zero when closed. Therefore, the flow rate can be variably adjusted in the range from 0 to the fully open flow rate by rotating the rotary cylinder 77a leftward or rightward.

Further, when the socket and the plug are separated, in both pipe joints, the slide valves 83, 83a for controlling the flow rate provided on the plugs 85, 85a side are pressed by the elastic force of the springs 87, 87a, respectively, and the flow passage is formed. In order to close the pipe, the fluid is blocked at the moment the pipe joint is separated, and the closed state is maintained until the pipe is connected again by the above method.

Next, a second embodiment of the present invention will be described.

Supply / exhaust hose 10 for the supply / exhaust source of compressed air to 0, 101
3 are connected via a pipe joint 104. In addition,
The pipe joint 104 is the socket 75 used in the above embodiment.
Alternatively, the pipe joint 150 in which the flow rate adjusting mechanism is provided in the plug 85 is adopted.

To explain the method of use and the operation of the present embodiment, the hand bag 100 is placed in the hand that is bent like a knuckle, with the loop side of the folded bag body being applied to the palm surface. The insert 102a is inserted and wound around the finger such as the thumb or the index finger to be fixed. In this example, it is fixed by a velvet fastener provided on the attachment. The arm bag 101 is attached to the inside from the hand a to the lower arm c so that the V-shaped hooks 105 are directed toward the palm, and the attachments 102b and 102c are attached to the wrist b and the lower arm c. Is fixed in the same manner as above. In this way, after the preparation is completed, the hand bag body 1
00 and the bag 101 for arms are supplied and exhausted with compressed air. When air supply / exhaust is performed on the finger bag body 100,
As shown by the chain line in FIG. 13, the bag body 100 expands from the undelivered state shown by the solid line in FIG. 13 to open the hand from the centripetal direction. In this state, it is carried to a hand and an appropriate small object m, and a posture for holding the small object m with fingers is prepared. Next, when the compressed air is forcibly discharged, the hand bag body 100 contracts and holds the small object m. Then, compressed air is supplied to the arm bag 101 to inflate it. As the arm bag 101 expands, the V-shaped hook 105 rises up and presses the palm surface with its tip, so that the wrist b bends back from the tip to the back side and at the same time lifts the hand holding the small object m. . Furthermore, after the required time has elapsed, when compressed air is also supplied to the hand bag body 100 to inflate it, the fingers are opened again and the small object m is opened, as shown in FIG. By repeating such work, extension / contraction and expansion movements of hands, fingers, arm joints and the like are repeated.

In this example, when the above-mentioned movement is repeated, the flow rate adjusting mechanism 15 is attached to the socket 75 or the plug 85 as described above.
Since the pipe joint 104 provided with 0 is attached to the air supply / exhaust hose 103, in addition to the above, the same operational effect as the above-described embodiment can be exhibited.

Next, a third embodiment of the present invention will be described.

In this embodiment, as shown in FIGS. 15 and 16, fingers are fitted to the outer peripheral surface on the back side of a cylindrical air bag 110 (main body of function improver) that repeatedly expands and contracts by supplying and exhausting compressed air. While providing the finger fitting rings 112a to 112e,
Connecting member 113 for fixing the arm joint part or its vicinity
Fixed band 1 with a, 113b, 114a, 114b
13, 114 are further provided, and a hose connecting socket 115 provided in the cylindrical air bag 110 is connected with a supply / exhaust hose 116 of a supply / exhaust source of compressed air through a pipe joint 111. The pipe joint 111 employs a pipe joint in which the socket 75 or the plug 85 used in the above embodiment is provided with the flow rate adjusting mechanism 150. Although a velvet fastener is used as the connecting member, other means such as a string or a button may be used, and only one fixing band may be provided.

The method of use and the operation of the present embodiment will be described. First, the back surface of the hand of the dysfunctioned hand is applied to the surface of the air bag 110 in a contracted state, and each finger is placed on the air bag 110.
It is inserted into the finger fitting wheels 112a to 112e provided on the surface of the. Next, the wrist part and the arm part are wound by the fixing bands 113 and 114, and the connecting members 113a, 113b and 114a, 11a each made of a velvet fastener are provided at the respective tips.
4b is adhered and the back of the hand is tightly fixed to the surface of the air bag 110. In this state, compressed air is supplied to the air bag 110 to
Inflate 10. Due to the expansion force of the air sacs 110, the air sacs 1
As shown in FIG. 16, the hand applied to 10 is subjected to the action of bending back to the back of the hand, and the hand muscles, tendons, joints, etc. are sufficiently extended. Then, conversely, the compressed air is exhausted and the air bag 110 is contracted. By repeating such an operation, the air bag 110
Repeats expansion and contraction, whereby the back and fingers can be positively expanded and expanded from the back of the hand.

In this example, when the above-mentioned movement is repeated, the flow rate adjusting mechanism 15 is attached to the socket 75 or the plug 85 as described above.
Since the pipe joint 111 provided with 0 is attached to the air supply / exhaust hose 116, in addition to the above, the same operational effects as the above-described embodiment can be exhibited.

(Effects of the Invention) According to the present invention described above, when the pipe joint is separated, the valve built in the pipe joint immediately closes the flow path, so that the function improving device main body can be supplied with compressed air. Further, it is possible to move to another place and perform another exercise such as another rehabilitation at the same time in addition to the function improvement of the hand, finger, etc. according to the present invention.
