Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a diagnostic device for the rehabilitation status of multiple joints in the upper limb. Background Art

[0002] Fracture is a common type of joint injury. As a key indicator for judging the rehabilitation status of fractures, during the diagnosis process, tools such as a protractor are often used for evaluation. In upper limb fractures, the elbow, wrist, and hand are relatively common fracture joint sites. Chinese Patent Authorization Announcement CN221980736U discloses a device for measuring the range of motion of the elbow joint, including: a measurement component. The measurement component includes a first housing and a second housing. A driving member is provided between the first housing and the second housing. The indicating member can also rotate with the flexion and extension component. According to the position of the indicating member, the scale of the corresponding scale line can be seen, thereby facilitating the staff to observe the rotation angle and enabling the accurate angle of joint range of motion to be obtained. The above-mentioned prior art solutions have the following deficiencies: This device mainly judges the mobility of the elbow by the relative rotation between the flexion and extension component and the upper arm placement component. However, in fact, the elbow movement covers two main aspects: the flexion and extension of the forearm and the rotation of the forearm. This device can only achieve the diagnosis of the flexion and extension mobility of the elbow, but it is not easy to effectively diagnose the rotational mobility of the elbow. Therefore, it is impossible to comprehensively evaluate the flexibility of the elbow during multi-angle movement, resulting in obvious deficiencies in its application in fracture rehabilitation diagnosis.

Detailed implementation mode

[0017] It is easy to understand that according to the technical solution of the present invention, without changing the essence of the present invention, those of ordinary skill in the art can propose various structural forms and implementation methods that can be mutually replaced. Therefore, the following detailed implementation modes and drawings are only illustrative descriptions of the technical solution of the present invention, and should not be regarded as all of the present invention or as a limitation or restriction on the technical solution of the present invention.

[0018] In the first embodiment, in order to solve the problem that it is difficult to diagnose the multi-angle mobility of the elbow in the prior art, the following solution is disclosed. Specifically, as Figures 1-3 、 Figure 5 、 Figure 6 shown: An upper limb multi-joint trauma rehabilitation status diagnosis device, comprising: a support member 1, with turntables 2 rotatably connected to both sides of the support member 1. A pointer A 3 is fixed to one side of the support member 1, and the pointer A 3 points to the scale line located outside the turntable 2 on one side. A drive switching component 8 is arranged outside the turntable 2 on the other side. Connecting frames 4 are fixed to the front ends of the turntables 2, and sliding frames 5 are slidably installed inside the connecting frames 4. The front ends of the sliding frames 5 are jointly connected to a torsion diagnosis mechanism 6. The torsion diagnosis mechanism 6 includes a fixed ring 61 fixedly connected between the two sliding frames 5. A rotating ring 62 is rotatably connected to the front end of the fixed ring 61. A resistance adjustment component 63 is connected between the rear end of the rotating ring 62 and the fixed ring 61. A pointer B 64 is fixed to the front end of one of the sliding frames 5, and the pointer B 64 points to the scale line located on the outer wall of the rotating ring 62. A fixed block 7 is fixed to the top of the front end of the rotating ring 62. A clamping component 9 is arranged on the inner wall of the rotating ring 62. The clamping component 9 includes elliptical air bags 91 fixed to two opposite inner walls of the rotating ring 62. The top end of the fixed block 7 is rotatably connected to a rotating sleeve 94. The bottom end of the rotating sleeve 94 is communicated with a one-way air inlet pipe 92. Both ends of the one-way air inlet pipe 92 penetrate through the inside of the rotating ring 62 and are connected to one side of the adjacent elliptical air bag 91. A connecting head 95 is fixed to the front end of the rotating sleeve 94, and the front end of the connecting head 95 is connected to an external air injection device. A pointer C 96 is fixed to the rear end of the rotating sleeve 94 relative to the connecting head 95. The bottom ends of the outer sides of the elliptical air bags 91 are jointly connected to a one-way exhaust pipe 93, and the bottom end of the one-way exhaust pipe 93 penetrates to the outside of the rotating ring 62; Specifically, as Figure 1 , Figure 2 , Figure 5 , Figure 6 shown, by using the cooperation of the turntable 2, the pointer A 3, the connecting frame 4 and the sliding frame 5, the diagnosis of the flexion and extension movement flexibility of the forearm can be realized. By using the cooperation of the locking strap 104, the rotating ring 62, the fixed ring 61 and the clamping component 9, the fixation of the wrist can be realized, and then the diagnosis of the torsion flexibility of the forearm can be realized, and the diagnosis effect of the multi-angle flexibility of the elbow can be realized. With the cooperation of the electromyography inductor 15, the reaction of the muscles during elbow movement can be further monitored, so as to improve the accuracy of the diagnosis. By using the sliding connection mode between the connecting frame 4 and the sliding frame 5, the device can be adapted to the diagnosis of people with different arm lengths. At the same time, by using the inflation expansion effect of the elliptical air bag 91, the clamping effect on wrists of different thicknesses can be adapted. Moreover, the inflation of the elliptical air bag 91 realizes the flexible clamping of the wrist, improves the comfort of the rehabilitator, and the left-right distribution of the two elliptical air bags 91 can conform to the structural characteristics of the wrist and realize the stable clamping effect on the wrist; The support component 1 includes a support base 101. At the front part of the top of the support base 101, an elbow groove 103 is provided. At the rear part of the top of the support base 101, a humerus groove 102 is provided. Locking straps 104 are evenly installed inside the humerus groove 102. The turntable 2 is located outside the elbow groove 103, and the drive switching component 8 is located outside the humerus groove 102. Electromyographic sensors 15 are attached to the inner sides of both the locking straps 104 and the elliptical airbag 91. Specifically, as Figure 2 shown, by using the cooperation of the humerus groove 102 and the elbow groove 103 to determine the placement position between the forearm and the humerus, and then confirm the position of the elbow joint, so as to ensure that the rotation point of the turntable 2 conforms to the activity point of the elbow, thereby realizing the measurement and diagnosis effect of the flexion and extension angle of the forearm.

[0019] In this embodiment, when in use, the forearm penetrates through the center of the fixing ring 61, and the wrist is located between the elliptical airbags 91. Connect an external air injection device to the connection head 95, and the gas enters the one-way intake pipe 92 through the rotating sleeve 94 unidirectionally and accumulates in the elliptical airbag 91, causing the elliptical airbag 91 to expand. Then, the two left and right elliptical airbags 91 clamp and fix the upper and lower ends of the wrist, making the electromyographic sensor 15 on the elliptical airbag 91 fit the wrist skin. Then, telescopically move the sliding frame 5 so that the elbow is located in the elbow groove 103 and the humerus is located on the humerus groove 102. Then, tighten and fasten the locking strap 104 to clamp and fix the humerus, making the electromyographic sensor 15 on the inner side of the locking strap 104 fit the humerus skin. During diagnosis, by autonomously lifting the forearm, the forearm drives the fixing ring 61 to move upward, the sliding frame 5 drives the connecting frame 4, and the turntable 2 rotates. Thus, the pointer A3 indicates the scale lines at different positions on the outside of the turntable 2, and the scale is observed to diagnose the flexion and extension angle of the elbow and its flexibility. Since the two left and right elliptical airbags 91 clamp both sides of the wrist, by autonomously rotating the forearm, the rotating ring 62 is driven to rotate along the front end of the rotating ring 62. Thus, the pointer B64 indicates the scale lines at different positions on the outer wall of the rotating ring 62, and the scale is observed to diagnose the pronation and supination angles of the forearm and the rotational flexibility of the elbow. During the above activities, the signals of the electromyographic sensor 15 are synchronously accessed for diagnosis to diagnose the muscle activity during joint movement and further diagnose the recovery degree of rehabilitation. During the diagnosis process, the flexion and extension of the forearm can be coordinated with the rotation of the forearm synchronously to further diagnose the multi-angle movement flexibility of the elbow joint.

[0020] Embodiment 2, in order to further achieve the rehabilitation training effect of the elbow, the drive switching component 8 is used to assist the forearm in flexion and extension training, and the resistance adjustment component 63 is used to adjust the resistance of the forearm rotation. Therefore, the following solution is disclosed. Specifically, as Figures 2-4 shown: The driving switching component 8 includes a driving gear 82 rotatably connected to the outside of the support base 101. A self-locking motor 81 is installed on the outside of the support base 101 through a support frame. The output end of the self-locking motor 81 is connected to the rotating shaft of the driving gear 82. A guiding groove 83 is formed on the outside of the support base 101. A sliding member 84 is slidably installed inside the guiding groove 83. A transmission gear 85 is rotatably connected to the outside of the sliding member 84. The transmission gear 85 meshes with the driving gear 82. A toothed ring 86 is sleeved on the outside of the adjacent turntable 2 of the driving gear 82; The main view cross-section of the guiding groove 83 is a quarter-circular arc structure centered on the driving gear 82. The guiding groove 83 is located between the driving gear 82 and the toothed ring 86. A rotating damping ring is provided between the transmission gear 85 and the sliding member 84. When the transmission gear 85 moves from the rightmost end to the leftmost end of the guiding groove 83, the transmission gear 85 contacts and meshes with the toothed ring 86; Specifically, as Figure 2 shown, in conventional technical means or what is easily thought of, during the rehabilitation training stage, the flexion and extension movement of the forearm is controlled with the help of external force. However, this method increases the operation difficulty during the rehabilitation training of the elbow joint and requires the cooperation of others. According to the device for measuring the range of motion of the elbow joint disclosed in the patent with the publication number CN221980736U, it mainly uses a detachable electric component to assist in driving the flexion and extension movement of the forearm. However, in this method, since the electric component needs a manual component on the connecting shaft, it cannot be freely switched between the training and diagnosis modes. Through the guiding action of the guiding groove 83, when the driving gear 82 rotates counterclockwise, due to the damping effect between the sliding member 84 and the transmission gear 85, the driving gear 82 drags the transmission gear 85 to move from the rightmost side to the leftmost side, causing the transmission gear 85 to mesh with the toothed ring 86. Under the continuous rotation of the driving gear 82, the toothed ring 86 rotates counterclockwise to realize the lifting rotation of the connecting frame 4. When the driving gear 82 rotates clockwise, the driving gear 82 drives the transmission gear 85 to reset, separating the transmission gear 85 from the toothed ring 86 to release the assistance control of the connecting frame 4 for the autonomous lifting diagnosis of the elbow joint; The resistance adjusting component 63 includes a movable ring 631 movably sleeved outside the fixed ring 61. A threaded groove 633 is provided at one end of the outside of the fixed ring 61 close to the rotating ring 62. A plurality of U-shaped guide cylinders 632 are equidistantly fixed at the rear end of the fixed ring 61. A tensioning rope 634 penetrates through each of the U-shaped guide cylinders 632. The front ends of the tensioning ropes 634 are fixedly connected to the rear end of the movable ring 631. The rear ends of the tensioning ropes 634 penetrate through the cavities in the inner wall of the fixed ring 61 and are fixedly connected to the rear end of the rotating ring 62; Specifically, as Figure 3 、 Figure 4As shown, it is a common technical means or easy to think of directly using the rotational property between the rotating ring 62 and the fixed ring 61 to achieve the diagnosis of the torsional mobility of the elbow joint. However, during rehabilitation diagnosis, the flexibility of elbow joint torsion is also the key to diagnosis. Through the setting of the resistance adjustment component 63, a traction force is provided to the rear end of the rotating ring 62, and the magnitude of the traction force is adjusted by adjusting the tension of the tensioning rope 634, so as to have a good exercise effect on the rehabilitation training of elbow joint torsion; The internal of the thread groove 633 and the movable ring 631 is in threaded connection, the front end of the U-shaped guide cylinder 632 and the rear end of the movable ring 631 are magnetically fixed, and the thread groove 633 and the U-shaped guide cylinder 632 are arranged at intervals; Specifically, as Figure 3 、 Figure 4 As shown, it is a common technical means or easy to think of to fix and adjust the position of the movable ring 631 on the fixed ring 61 by means of clamping, positioning hole bolts, etc. However, the distance of a single adjustment of the movable ring 631 by this method is fixed, resulting in a reduction in the adjustable precision. By using threaded connection and magnetic fixation, the specific operation of adjusting the position of the movable ring 631 is more convenient. At the same time, under the transformation of the two methods of magnetism and thread, it is possible to directly switch between zero resistance and resistance. By using threaded connection, the movable ring 631 can generate a certain outward screwing movement, and the movement distance is more subtle, so as to achieve the fine adjustment effect of the resistance magnitude; The tensioning rope 634 includes a connecting rope 6341 fixed to the rear end of the fixed ring 61. One end of the connecting rope 6341 is connected with a tensioning adjustment spring 6342. One end of the tensioning adjustment spring 6342 is connected with a reserved adjustment rope 6343. One end of the reserved adjustment rope 6343 passes through the inside of the U-shaped guide cylinder 632 and is connected with the rear end of the movable ring 631. When the movable ring 631 and the U-shaped guide cylinder 632 are magnetically fixed, the reserved adjustment rope 6343 and the tensioning adjustment spring 6342 are both in a loose state; Specifically, as Figure 4 As shown, it is a common technical means or easy to think of to directly adjust the stretching amount of a tensioning adjustment spring 6342 to achieve the adjustment effect of the rotational resistance of the rotating ring 62. However, this method will inevitably be affected by resistance during the rotation of the forearm. For patients with incomplete recovery of elbow trauma, resistance should be minimized during the early rehabilitation training. Therefore, by increasing the reserved length of the reserved adjustment rope 6343 inside the fixed ring 61, when the rotating ring 62 rotates, it will not produce a stretching effect on the tensioning adjustment spring 6342, so as to achieve the effect of zero resistance.

[0021] In this embodiment, when in use, during the rehabilitation training stage, the self-locking motor 81 is started to rotate the driving gear 82. Since the driving gear 82 and the transmission gear 85 are always meshed, and there is a damping effect at the rotation connection between the transmission gear 85 and the sliding member 84, the driving gear 82 first drives the transmission gear 85 to slide along the guide groove 83 through the rotation of the teeth, so that the transmission gear 85 moves from the right side to the left side, so that the transmission gear 85 and the gear ring 86 come into contact and mesh, and as the driving gear 82 continues to rotate, the transmission gear 85 drives the gear ring 86 rotates, so that the gear ring 86 drives the turntable 2 to rotate, so that the turntable 2 drives the connecting frame 4 to lift up, and the self-locking of the self-locking motor 81 is used to fix the lifting angle of the elbow, thereby assisting the forearm lifting action of the elbow injured person. When the self-locking motor 81 rotates in the opposite direction, it drives the transmission gear 85 to rotate synchronously, and makes the transmission gear 85 gradually move away from the gear ring 86, thereby releasing the restriction on the rotation angle of the turntable 2, so that the forearm can automatically fall back. At the same time, because the transmission gear 85 and the gear ring 86 are not meshed at this time, the self-help activities of the rehabilitated person are not hindered in the subsequent diagnosis process. By moving the movable ring 631 forward, the movable ring 631 and the U-shaped guide cylinder 632 are separated, and the movable ring 631 is threadedly sleeved on the thread groove 633, so that the movable ring 631 generates a forward traction force on the reserved adjustment rope 6343, so that the reserved adjustment rope 6343 located inside the fixed ring 61 is changed from a loose state to a tensioned state, and the tension adjustment spring 6342 is in a straight line. Therefore, when the wrist rotates, the rotation of the rotating ring 62 along the fixed ring 61 will drive the tension adjustment spring 6342 to lengthen, and the elastic force of the tension adjustment spring 6342 is utilized to make the wrist feel the rotation resistance, so as to achieve the strengthening effect of rehabilitation training, and the movable ring 631 is continuously twisted on the thread groove 633 to fine-tune the outward stretching distance of the reserved adjustment rope 6343, so as to adjust the initial stretching length of the tension adjustment spring 6342, and the size of the forearm rotation resistance can be further adjusted, and the corresponding rehabilitation training intensity can be adapted as needed.

[0022] Embodiment 3, in order to further realize the rehabilitation diagnosis function of multiple joints, the inflatable component 11 and the groove 12 are used to achieve the rehabilitation training and diagnosis effect of wrist and hand flexibility, so the following scheme is disclosed, specifically as follows Figure 1 , Figure 2 and Figure 7 , Figure 8 As shown: The front end of the connector 95 is clamped with an inflatable component 11, and the inflatable component 11 includes an L-shaped inflatable valve tube 112 clamped on the front end of the connector 95, one end of the L-shaped inflatable valve tube 112 is connected to an inflatable airbag 111, a finger ring 114 is evenly fixed on one side of the inflatable airbag 111, and a one-way inflatable tube 113 is provided at the bottom end of the inflatable airbag 111; Specifically, as Figure 7 shown, by compressing the inflatable airbag 111, the inflation effect inside the elliptical airbag 91 can be realized, and by applying pressure to the inflatable airbag 111 by hand to close it inward, the rehabilitation training effect on the finger part can be realized, and the multi-joint diagnosis and rehabilitation training functions of the device can be realized; The L-shaped inflatable valve tube 112, the connector 95, and the pointer C96 are collinearly distributed. On both sides of the top of the fixed block 7, an angle scale 10 is fixed through a support block. The angle scale 10 and the rotating sleeve 94 are coaxially collinearly distributed, and the pointer C96 points to the scale line at the top of the angle scale 10; Specifically, as Figure 8 shown, in conventional technical means or what is easily thought of, a protractor is directly used to diagnose and detect the flexion and extension of the wrist. However, this method requires the measurer to first calibrate the turning point of the wrist flexion and extension, which mainly depends on the judgment of the detector. However, through the functions of the L-shaped inflatable valve tube 112, the rotating sleeve 94, and the angle scale 10, when the rehabilitee grasps the inflatable airbag 111, the turning point of the wrist is basically aligned with the angle scale 10, so as to facilitate direct diagnosis, and through the cooperation of the angle scale 10 and the pointer C96, the flexion and extension angle of the wrist can be viewed; On one side of the inflatable airbag 111 close to the finger ring 114, grooves 12 are evenly arranged. The grooves 12 and the finger ring 114 are alternately spaced. Elastic ropes 14 are fixed on the side walls of the grooves 12 far from the openings. The front ends of the elastic ropes 14 are fixedly connected with display cloths 13, and both ends of the display cloths 13 are respectively connected to the outer edges of the upper and lower ends of the grooves 12; Specifically, as Figure 8 shown, in conventional technical means or what is easily thought of, springs are installed between the fingers for training. However, due to the certain length of the springs themselves in this method, there will be a certain opening gap between the fingers in the initial state. Through the grooves 12, combined with the gas expansion effect in the inflatable airbag 111, the openings of the grooves 12 are basically closed in the initial state, so it is easy to ensure that the hand can completely change from the closed state to the unfolded state, so as to achieve an effective training effect.

[0023] In this embodiment, when in use, the L-shaped inflatable valve tube 112 is inserted into the inside of the connector 95 to connect the inflatable airbag 111 and the rotating ring 62. After the wrist passes through the rotating ring 62, the fingers can be correspondingly inserted into the finger rings 114, and then the inflatable airbag 111 can be rotated and held. By closing the fingers inward, the air in the inflatable airbag 111 enters the rotating sleeve 94 from the L-shaped inflatable valve tube 112, thereby realizing the inflation of the elliptical airbag 91. On the one hand, by using the opening and closing movement of the hand, while achieving finger training, it can automatically clamp the wrist, so that when the device is in use, it can first perform a rehabilitation diagnosis on the fingers and then perform a diagnostic operation on the elbow; On the basis of wrist clamping, by holding the inflatable airbag 111 with the hand and using the autonomous flexion and extension movement of the wrist, the L-shaped inflatable valve tube 112 is driven to rotate along the rotating sleeve 94, so that the pointer C96 moves in the reverse direction, and the pointer C96 indicates different scales on the angle scale 10, and then the flexion and extension range of motion of the wrist is diagnosed; Since the fingers penetrate into the finger rings 114, by expanding between the fingers, the distance between adjacent finger rings 114 is increased, the opening of the groove 12 is increased, the upper and lower ends of the display cloth 13 are separated from each other, the display cloth 13 changes from a folded state to an unfolded state, and the elastic rope 14 is stretched, so that the flexibility of the finger joints can be further diagnosed and rehabilitated. And when the fingers are closed together, under the elastic action of the elastic rope 14, the display cloth 13 is automatically folded and stored inside the groove 12.

Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
