DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous passive exercise training apparatus for joints including a wrist joint.

[0002]

2. Description of the Related Art When a fracture or joint surgery is performed, the range of motion of the joint after surgery is secured early, extra-articular contracture or intra-articular adhesions are avoided, and swelling and pain after surgery are reduced. A joint continuous passive exercise training device is used as a means. It is preferable that the training of the continuous joint passive exercise be performed with an appropriate amount of exercise necessary for the training without applying excessive force to the living body of the patient. In particular, the way of movement of the joint is not a uniaxial but a multi-axis swinging and rotating complex movement, and furthermore, the amount of movement is not uniform and there are considerable individual differences, and the individuality of the way of movement considerably appears depending on the patient's symptoms. However, the conventional continuous passive exercise training apparatus for joints generally includes a drive motor fixed to a brace for attachment to a site near a joint and a swinging device connected to a brace or a grip for attachment to a free end of a joint. With the arm, the range of motion was simply set by setting the swing angle at 0 ° to α ° for the dorsiflexion and 0 ° to β ° for the palm flexion to drive the arm. For this reason, during training, the practitioner operates the device with a narrow movable angle range while watching the patient's condition, and when there is no pain in that range, sets the moderately wide movable angle range and activates the device. It is necessary to operate the device so as to gradually increase the movable angle range, which may cause pain to the patient due to excessive angle setting, and it may take a lot of time and effort to set the proper movable range. There was a problem of doing. Further, in the conventional device, since the arm can only perform a simple uniaxial swinging motion, there is a problem that it is difficult to match the actual movement of the joint, and extra stress is applied to the affected part.

[0018]

Next, the operation and operation of the apparatus according to the present invention will be described. In use, the power switch 120 is turned off, the clutch lever 110 is set to the on state, and the power switch 120 is turned on in this state. In this case, the driving of the motor 10 is performed via the clutch 11 by the driving pulley 13a →
Since the rotation shaft 131 rotates by being transmitted from the endless belt 13c to the driven pulley 13b, the rotation arm 2 swings. The power switch 120 is turned off when the position of the rotary arm 2 becomes horizontal (0 °), that is, when the angle display section 416 of the fixed dial 41 is aligned with the zero point display section 7 of the arm cover 100c. In this state, the dust cover 10
0e, the second movable dial 42 of the movable range setting dial 4a is gripped and turned clockwise, and the rotation is stopped when the dock portion 427 abuts against one side of the switch lever 47 as a stopper. Next, the first movable dial 40 is gripped and turned counterclockwise, and the rotation is stopped when the dock portion 407 contacts the other side of the switch lever 47.
FIG. 7 shows this state, which can be easily confirmed by visually observing the positions of the starting point display portions 8 and 8 ′ of the first movable dial 40 and the second movable dial 42. The first movable dial 40 and the second movable dial 42 are rotatably fitted to bosses 412 and 412 of the fixed dial 41 and
03, 403 ', which are pressed from the thickness direction.
414 is smoothly rotated relative to the ratchet while sliding. In this state, the brace 3 is mounted on the forearm. Preferably, the mounting is such that the rotating shaft 131 substantially coincides with the joint.

Thus, the preparation is completed. Now, assuming that continuous passive exercise training of dorsiflexion and buckling is performed, first, the grip ball 5 connected to the slide portion 2c of the rotating arm 2 is used.
a is gently gripped with the palm and lightly fixed with the grip band 5b. Then, the practitioner releases the clutch lever 110 while holding the patient's hand. To determine the range of motion of the wrist joint, the practitioner performs dorsiflexion and palmarity while checking the patient's condition with his hands. In this case, the rotating shaft 131 rotates in accordance with the tilting of the rotating arm 2, and the fixed dial 41 rotates by the same rotation angle by the rotation of the rotating arm 2 in the dorsiflexion direction. The engaged first movable dial 40 is also rotated in the clockwise direction. At this time, the second movable dial 42 does not move because the dock portion 427 is in contact with the switch lever 47, and the fixed dial 41 relatively rotates. Therefore the second
The dorsiflexion angle is automatically determined by the movable dial 42. Also, if the rotating arm 2 is reversed and rotated in the palm bending direction, the second movable dial 42 meshing with the fixed dial 41 and the knurls 414 and 424 is rotated counterclockwise by the same rotation angle rotation of the fixed dial 41. It is rotated together. At the time of this counterclockwise rotation, the first movable dial 40 is also carried along with the fixed dial 41. However, when the dock portion 407 abuts on the switch lever 47, the first movable dial 40 is not moved. 4
With 0, the palm flexion angle is automatically set.

Since the above operation is performed by the practitioner actually bending the patient's joints and manually instructing the apparatus on the range of dorsiflexion and palmar flexion movement, it is possible to determine the optimal range of motion according to the patient's condition. it can. After that, the clutch lever 110
Is turned on, and the power switch 120 is turned on. In this case, the driving of the motor 10 is started from the clutch 11 → the drive shaft 111 →
The driving force is transmitted to the rotating shaft 131 via the driving pulley 13a → the endless belt 13c → the driven pulley 13b, and the rotating arm 2 connected thereto reciprocates in the dorsiflexion direction and the palmflexion direction. At this time, when the rotary arm 2 swings in the dorsiflexion direction, the second movable dial 42 rotates together with the fixed dial 41, so that the dock portion 427 thereof comes into contact with the switch lever 47. As a result, the switch 4b is turned on, an inversion signal is sent to the drive circuit of the motor 10, and the rotation direction is reversed. When the rotary arm 2 swings in the palm bending direction, the first movable dial 40 rotates together with the fixed dial 41, and the dock portion 407 of the first movable dial 40 contacts the switch lever 47. Thereby, the switch 4b
Is turned on, an inversion signal is sent to the drive circuit of the motor 10, and the rotation direction is reversed. Hereinafter, the dorsiflexion and buckling in the movable range set as described above are repeated by the same operation. Therefore, rehabilitation can be performed without giving a patient unreasonableness and pain. If it is necessary to change the above-mentioned dorsiflexion / palmiflexion movable range at the time of actual exercise, the power switch 120 is turned off and the first movable dial 40 and / or the second By turning the movable dial 42, the angle can be increased or decreased.

The motion of the joint of the human body is not a single axis but a multi-axis swing rotation complex motion. Moreover, the patient has unique joint motion characteristics, and the position of the wrist joint and the rotating shaft 131 may not always match. However, in the present invention, the rotary arm 2 has the slide portion 2c, which can move in the axial direction with respect to the main portion 2b. Further, since the main part 2b is connected to the base 2a by the hinge mechanism 2d,
The rotating arm 2 can be appropriately bent in a direction perpendicular to the swing surface. As a result, it is possible to realize a movement faithfully following the actual movement of the joint of the patient, and it is possible to avoid applying extra pain and stress to the patient and the affected area. If bending in the direction perpendicular to the rocking surface is unnecessary or inconvenient for treatment, the locking means 2e in the form of a sleeve may be moved to the area of the hinge mechanism 2d. Pin 2
03 does not function as a fulcrum because the base 2a and the main part 2
b is integrated and only slide is possible. After continuous dorsiflexion and buckling exercise training for a certain period of time, rotate arm 2
When the is in the horizontal position, the power switch 120 may be turned off and the device may be removed from the patient. Although the above description is for dorsiflexion and palmarflexion exercise training, it is needless to say that squatting and squatting exercise training can be performed by changing the mounting position. The usage and operation of the second to fifth embodiments are the same as those described above.

It should be noted that the grip ball 5 as in this embodiment is used.
When a is adopted, since there is no directionality, the gripping position is not determined as in the case of the normal rod handle type, and there is no need for complicated work such as changing the grip angle. There is.

It has a movable dial 40 and a second movable dial 42 for setting a swinging end on the other side, and these are mounted on both sides of a fixed dial 41 that rotates integrally with the rotating shaft 131 so as to be relatively rotatable therewith. Since the first movable dial 40 and the second movable dial 42 have dock portions 407 and 427 that can abut on the lever 47 of the switch 4b, the practitioner can directly connect the patient's joint with the clutch 11 disengaged. The rotation shaft 131 rotates in accordance with the tilting of the rotary arm 2 only by bending, and the relative rotation of the fixed dial 41 and the first movable dial 40 and the second movable dial 42 and the dock portion 407,

An excellent effect is obtained that appropriate joint exercise training can be carried out without giving any movement, and the movable range setting and copying operation can be realized by the movable range setting copying mechanism 4 having a simple and compact structure. Can be According to the second aspect, since the rotary arm 2 has the slide portion 2c that can move in the axial direction, the joint exercise training can be smoothly performed even when the position of the joint and the rotary shaft is displaced. Excellent effect that can be obtained. According to the third aspect, since the rotary arm 2 has the slide portion 2c movable in the axial direction and can be bent in the direction perpendicular to the swinging surface by the hinge mechanism 2d, the rotation of the actual joint can be prevented.
