[0028] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0029] 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. Figure 1-Figure 3 、 Figure 5 、 Figure 6 As shown:

[0030] A device for diagnosing the rehabilitation status of multiple joint trauma of an upper limb, comprising: a supporting component 1, a turntable 2 being rotatably connected on both sides of the supporting component 1, a pointer A3 being fixed on one side of the supporting component 1, the pointer A3 pointing to the scale line located on the outside of the turntable 2 on one side, a drive switching component 8 being provided on the outside of the turntable 2 on the other side, a connecting frame 4 being fixed on the front end of the turntable 2, a sliding frame 5 being slidably installed on the inner side of the connecting frame 4, a torsion diagnostic mechanism 6 being commonly connected to the front end of the sliding frame 5, the torsion diagnostic mechanism 6 comprising a fixed ring 61 fixedly connected between the two sliding frames 5, the front end of the fixed ring 61 being rotatably connected to a rotating ring 62, a resistance adjustment component 63 being connected between the rear end of the rotating ring 62 and the fixed ring 61, a pointer B64 being fixed on the front end of the sliding frame 5 on one side, the pointer B64 pointing to the scale line located on the The scale lines on the outer wall of the rotating ring 62, the top of the front end of the rotating ring 62 is fixed with a fixed block 7, the inner wall of the rotating ring 62 is provided with a clamping assembly 9, the clamping assembly 9 includes an elliptical airbag 91 fixed on the two opposite inner walls of the rotating ring 62, the top of the fixed block 7 is rotatably connected to a rotating sleeve 94, the bottom end of the rotating sleeve 94 is connected to a one-way air intake pipe 92, both ends of the one-way air intake pipe 92 pass through the interior of the rotating ring 62 and are connected to one side of the adjacent elliptical airbag 91, the front end of the rotating sleeve 94 is fixed with a connector 95, the front end of the connector 95 is connected to the external pumping device, the rear end of the rotating sleeve 94 relative to the connector 95 is fixed with a pointer C96, the bottom end of the outer side of the elliptical airbag 91 is commonly connected to a one-way exhaust pipe 93, and the bottom end of the one-way exhaust pipe 93 passes through the outside of the rotating ring 62;

[0031] Specifically, such as Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 As shown, by utilizing the cooperation of the turntable 2, the pointer A3, the connecting frame 4 and the sliding frame 5, the diagnosis of the flexion and extension flexibility of the forearm can be realized. By utilizing the cooperation of the locking cassette 104, the rotating ring 62, the fixing ring 61 and the clamping assembly 9, the wrist can be fixed, and then the diagnosis of the torsional flexibility of the forearm can be realized, and the diagnosis effect of the multi-angle flexibility of the elbow can be realized. In conjunction with the action of the myoelectric sensor 15, the reaction of the muscles during the elbow movement is further monitored, thereby improving the accuracy of the diagnosis. By utilizing the sliding connection 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, the inflation effect of the elliptical airbag 91 is utilized to adapt to the clamping effect of wrists of different thicknesses, and the expansion effect of the elliptical airbag 91 realizes a flexible clamping of the wrist, thereby improving the comfort of the rehabilitated person. In addition, the left and right distribution of the two elliptical airbags 91 can conform to the structural characteristics of the wrist and achieve a stable clamping effect on the wrist.

[0032] The support component 1 includes a support base 101, an elbow slot 103 is provided at the front of the top of the support base 101, and an arm slot 102 is provided at the rear of the top of the support base 101. Locking tapes 104 are evenly installed inside the arm slots 102. The turntable 2 is located outside the elbow slot 103, and the drive switching assembly 8 is located outside the arm slot 102. The locking tape 104 and the inner side of the elliptical airbag 91 are both attached with electromyographic sensors 15.

[0033] Specifically, such as Figure 2 As shown, the upper arm slot 102 and the elbow slot 103 are used to determine the placement position between the forearm and the upper arm, and then the position of the elbow joint is confirmed to ensure that the rotation point of the turntable 2 is consistent with the active point of the elbow, thereby achieving the measurement and diagnosis effect of the flexion and extension angle of the forearm.

[0034] In this embodiment, when in use, the forearm is passed through the center of the fixing ring 61 so that the wrist is located between the oval airbags 91. The connector 95 is connected by an external air pumping device, and the gas is fed into the one-way air inlet pipe 92 in one direction through the rotating sleeve 94 and gathered in the oval airbag 91, so that the oval airbag 91 expands. Then, the left and right oval airbags 91 clamp and fix the upper and lower ends of the wrist, so that the myoelectric sensor 15 on the oval airbag 91 fits the skin of the wrist. Then, the sliding frame 5 is telescopically moved so that the elbow is located in the elbow groove 103 and the upper arm is located on the upper arm groove 102. Then, the locking cassette 104 is tightened and engaged to clamp and fix the upper arm so that the myoelectric sensor 15 on the inner side of the locking cassette 104 fits the skin of the upper arm.

[0035] During diagnosis, the forearm is lifted up by the forearm, so that the forearm drives the fixed ring 61 to lift up, and the sliding frame 5 drives the connecting frame 4, so that the turntable 2 rotates, so that the pointer A3 indicates the scale lines at different positions on the outside of the turntable 2, and the scales are observed to diagnose the flexion and extension angles of the elbow and its flexibility. Since the left and right elliptical airbags 91 clamp the two sides of the wrist, the forearm is rotated by the forearm to drive the rotating ring 62 to rotate along the front end of the rotating ring 62, so that the pointer B64 indicates the scale lines at different positions on the outer wall of the rotating ring 62, and the scales are observed to diagnose the forward and backward rotation angles of the forearm and the rotation flexibility of the elbow. During the above-mentioned activities, the signal of the electromyographic sensor 15 is synchronously connected to the diagnosis to diagnose the muscle activity during the joint movement, and further diagnose the degree of recovery of the rehabilitation. During the diagnosis process, the flexion and extension of the forearm can coordinate with the rotation of the forearm to further diagnose the multi-angle flexibility of the elbow joint.

[0036] In the second embodiment, in order to further achieve the rehabilitation training effect of the elbow, the drive switching component 8 is used to perform power training on the flexion and extension of the forearm, and the resistance adjustment component 63 is used to adjust the size of the forearm rotation resistance. Therefore, the following scheme is disclosed, specifically as follows: Figure 2-Figure 4As shown:

[0037] The drive switching assembly 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 guide groove 83 is opened on the outside of the support base 101. A sliding member 84 is slidably installed inside the guide groove 83. The outer side of the sliding member 84 is rotatably connected to a transmission gear 85. The transmission gear 85 and the driving gear 82 are meshed with each other. A gear ring 86 is sleeved on the outer side of the turntable 2 adjacent to the driving gear 82.

[0038] The guide groove 83 has a front cross-section that is a quarter-circular arc structure with the drive gear 82 as the center. The guide groove 83 is located between the drive gear 82 and the gear ring 86. A rotation 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 guide groove 83, the transmission gear 85 contacts and engages with the gear ring 86.

[0039] Specifically, such as Figure 2 As shown, conventional technical means or what is easy to think of is that, in the rehabilitation training stage, the flexion and extension movement of the forearm is controlled by external force, but this method increases the difficulty of operation during the elbow joint rehabilitation training process and requires the cooperation of others. According to the publication number CN221980736U, a device for measuring the range of motion of the elbow joint is disclosed, which mainly uses a detachable electric component to help drive the flexion and extension movement of the forearm. However, in this method, since the electric component requires the manual component on the connecting shaft, it is impossible to switch freely between the training and diagnosis modes, and the guide of the guide groove 83 The driving gear 82 has the function of dragging the transmission gear 85 from the rightmost side to the leftmost side due to the damping effect between the sliding member 84 and the transmission gear 85. The transmission gear 85 is meshed with the gear ring 86. With the continuous rotation of the driving gear 82, the gear ring 86 rotates counterclockwise to realize the lifting and rotation of the connecting frame 4. When the driving gear 82 rotates clockwise, the driving gear 82 drives the transmission gear 85 to reset, so that the transmission gear 85 and the gear ring 86 are separated, thereby releasing the power-assisted control of the connecting frame 4, so as to facilitate the autonomous lifting diagnosis of the elbow joint.

[0040] The resistance adjustment assembly 63 includes a movable ring 631 movably mounted on the outside of the fixed ring 61. A threaded groove 633 is provided on the end of the fixed ring 61 near the rotating ring 62. A plurality of U-shaped guide cylinders 632 are fixed to the rear end of the fixed ring 61 at equal intervals. Tension ropes 634 are passed through the interior of each of the U-shaped guide cylinders 632. The front ends of the tension ropes 634 are fixedly connected to the rear end of the movable ring 631. The rear ends of the tension ropes 634 pass through the cavity in the inner wall of the fixed ring 61 and are fixedly connected to the rear end of the rotating ring 62.

[0041] Specifically, such as Figure 3 、 Figure 4 As shown, conventional technical means or easily conceivable methods are to directly utilize the rotation between the rotating ring 62 and the fixed ring 61 to achieve diagnosis of elbow joint torsion mobility. However, in rehabilitation diagnosis, the flexibility of elbow joint torsion is also a key to diagnosis. By setting the resistance adjustment component 63, a traction force is applied to the rear end of the rotating ring 62. The magnitude of the traction force is adjusted by adjusting the tension of the tension rope 634, thereby achieving a good training effect for elbow joint torsion rehabilitation training.

[0042] The thread groove 633 and the inner portion of the movable ring 631 are threadedly connected, the front end of the U-shaped guide cylinder 632 and the rear end of the movable ring 631 are fixed by magnetic attraction, and the thread groove 633 and the U-shaped guide cylinder 632 are spaced apart.

[0043] Specifically, such as Figure 3 、 Figure 4 As shown, conventional technical means or easily conceivable methods are to fix and adjust the position of the movable ring 631 on the fixed ring 61 by means of snap-fitting, positioning hole bolts, etc., and this method is fixed for the distance of a single adjustment of the movable ring 631, so that the adjustable precision is reduced, and the use of threaded connection and magnetic fixation makes the specific operation of adjusting the position of the movable ring 631 more convenient. At the same time, under the conversion of the two methods of magnetic attraction and thread, it is possible to directly switch between zero resistance and resistance. The use of threaded connection allows the movable ring 631 to produce a certain outward screwing movement, and the movement distance is more subtle, thereby achieving a fine-tuning effect on the resistance size;

[0044] 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 to a tensioning adjustment spring 6342. One end of the tensioning adjustment spring 6342 is connected to a reserved adjustment rope 6343. One end of the reserved adjustment rope 6343 passes through the interior of the U-shaped guide cylinder 632 and is connected to 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 relaxed state.

[0045] Specifically, such as Figure 4As shown, conventional technical means or what is easy to think of is to directly adjust the stretching amount of a tensioning adjustment spring 6342 to achieve the adjustment 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 whose elbow injuries have not fully recovered, the resistance applied should be minimized as much as possible during the early rehabilitation training. Therefore, by adding a reserved length of the reserved adjustment rope 6343 inside the fixed ring 61, when the rotating ring 62 rotates, there will be no stretching effect on the tensioning adjustment spring 6342, thereby achieving a zero resistance effect.

[0046] 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 engaged, 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 to the left, so that the transmission gear 85 and the gear ring 86 come into contact and engage, and as the driving gear 82 continues to rotate, the transmission gear 85 drives the gear ring 86 rotates, causing the gear ring 86 to drive the turntable 2 to rotate, causing the turntable 2 to drive the connecting frame 4 to lift up. The self-locking of the self-locking motor 81 fixes the lifting angle of the elbow, thereby assisting the forearm lifting movement 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 causes the transmission gear 85 to gradually move away from the gear ring 86, thereby releasing the restriction on the rotation angle of the turntable 2 and allowing the forearm to automatically fall back. At the same time, since the transmission gear 85 and the gear ring 86 are not engaged at this time, the self-help activities of the recovering person will not be hindered during the subsequent diagnosis process.

[0047] 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, so that the tension adjustment spring 6342 is straight. 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. The elastic force of the tension adjustment spring 6342 is used to make the wrist feel the rotation resistance, thereby achieving the effect of strengthening rehabilitation training. By continuously twisting the movable ring 631 on the thread groove 633, the outward stretching distance of the reserved adjustment rope 6343 can be fine-tuned, thereby adjusting the initial stretching length of the tension adjustment spring 6342, and the size of the forearm rotation resistance can be further adjusted to adapt to the corresponding rehabilitation training intensity as needed.

[0048] 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 the wrist and hand flexibility. Therefore, the following scheme is disclosed. Figure 1 、 Figure 2 and Figure 7 、 Figure 8 As shown:

[0049] The front end of the connector 95 is clamped with an inflation assembly 11. The inflation assembly 11 includes an L-shaped inflation valve tube 112 clamped to the front end of the connector 95. One end of the L-shaped inflation valve tube 112 is connected to an inflation airbag 111. A finger ring 114 is evenly fixed on one side of the inflation airbag 111. The bottom end of the inflation airbag 111 is provided with a one-way inflation tube 113.

[0050] Specifically, such as Figure 7 As shown, the inflatable airbag 111 is compressed to inflate the inside of the elliptical airbag 91, and the hand is used to apply pressure to the inward closing of the inflatable airbag 111 to achieve a rehabilitation training effect on the finger part, thereby realizing the multi-joint diagnosis and rehabilitation training function of the device;

[0051] The L-shaped inflation valve tube 112, the connector 95, and the pointer C96 are collinearly arranged. An angle scale plate 10 is fixed to both sides of the top of the fixed block 7 via support blocks. The angle scale plate 10 and the rotating sleeve 94 are coaxially collinearly arranged. The pointer C96 points to the scale line at the top of the angle scale plate 10.

[0052] Specifically, such as Figure 8 As shown, conventional technical means or easily conceivable is to directly use a protractor to diagnose and test the flexion and extension of the wrist. However, this method requires the measurement personnel to first calibrate the turning point of the wrist flexion and extension, which mainly relies on the judgment of the measurement personnel. However, through the action of the L-shaped inflation valve tube 112, the rotating sleeve 94 and the angle ruler disk 10, when the patient grasps the inflatable airbag 111, the turning point of the wrist is basically aligned with the angle ruler disk 10, thereby facilitating direct diagnosis. The flexion and extension angle of the wrist can be checked by the cooperation of the angle ruler disk 10 and the pointer C96.

[0053] Grooves 12 are evenly distributed on one side of the inflatable airbag 111 near the finger ring 114. The grooves 12 and the finger ring 114 are alternately spaced. Elastic cords 14 are fixed to the sidewalls of the grooves 12 away from the opening. The front ends of the elastic cords 14 are fixedly connected to display cloths 13. The ends of the display cloths 13 are respectively connected to the upper and lower outer edges of the grooves 12.

[0054] Specifically, such as Figure 8As shown, conventional technical means or what is easy to think of is to train by setting up springs between the fingers. However, in this method, the springs themselves have a certain length, which will cause each finger to form a certain expansion gap in the initial state. Through the groove 12, the gas in the inflatable airbag 111 is expanded, so that the opening of the groove 12 is basically closed in the initial state, thereby easily ensuring that the hand can completely change from a closed state to an expanded state, so as to achieve an effective training effect.

[0055] In this embodiment, when in use, the L-shaped inflation valve tube 112 is inserted into the interior 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 ring 114, and then the inflatable airbag 111 can be twisted and gripped. By retracting the fingers inward, the air in the inflatable airbag 111 enters the rotating sleeve 94 from the L-shaped inflation valve tube 112, thereby achieving inflation of the elliptical airbag 91. On the one hand, by utilizing the opening and closing movement of the hand, the wrist can be automatically clamped while achieving finger training. When using the device, rehabilitation diagnosis of the fingers can be performed first, and then diagnosis of the elbow can be performed.

[0056] On the basis of wrist clamping, by holding the inflatable airbag 111, the autonomous flexion and extension of the wrist is utilized to drive the L-shaped inflation valve tube 112 to rotate along the rotating sleeve 94, thereby causing the pointer C96 to move in the opposite direction, so that the pointer C96 indicates different scales on the angle ruler disk 10, and then the flexion and extension range of the wrist is diagnosed;

[0057] As the fingers pass through the finger rings 114, the expansion between the fingers increases the spacing between adjacent finger rings 114, thereby enlarging the opening of the groove 12, moving the upper and lower ends of the display cloth 13 away from each other, and changing the display cloth 13 from a folded state to an unfolded state, thereby stretching the elastic cord 14, thereby further diagnosing and rehabilitating the flexibility of the finger joints. When the fingers are brought together, the elastic action of the elastic cord 14 automatically achieves the folding and storage effect inside the groove 12.

[0058] The technical scope of the present invention is not limited to the contents of the above description. 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.
