Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and in particular relates to a mobile device that facilitates the measurement of joint range of motion. Background Technology

[0002] Joint range of motion is a common assessment item in clinical rehabilitation medicine and disability assessment. Doctors use joint range of motion as an indicator to evaluate the degree of postoperative joint rehabilitation in patients, and in disability assessment, the degree of disability is determined by measuring the patient's joint range of motion. Therefore, accurate measurement of joint range of motion is crucial.

[0003] Existing technologies disclose several invention patents in the field of medical device technology. Among them, Chinese patent CN113080943B discloses a shoulder joint range of motion measuring device, including a support, a shoulder measuring component, and a stopping mechanism. The support includes a vertically extending column; the shoulder measuring component includes a fixed disc mounted on the column and a movable disc rotatably mounted within the fixed disc; the movable disc includes a housing with an inner cavity, on which a shoulder joint movable arm is hinged; the stopping mechanism is disposed within the inner cavity of the housing and includes a notched annular structure with a stopping layer on its outer side; when the first and last ends of the annular structure can abut together, the entire annular structure is subjected to compressive force, and the stopping layer moves away from the inner wall of the housing; when the first and last ends of the annular structure separate, the entire annular structure is subjected to tensile force, and the stopping layer presses against the inner wall of the housing, thus stopping the movable disc. This technical solution fixes the movable disc using the stopping mechanism, eliminating concerns about data distortion caused by patient shaking during movement, effectively reducing measurement errors.

[0004] Existing shoulder joint range of motion measurement devices still have some shortcomings in their application. The measurement method is relatively simple, which cannot provide medical staff with more reference data to determine the degree of shoulder joint injury in patients. In addition, they can only measure the range of motion of the patient's shoulder joint and cannot measure the range of motion of other joints.

[0005] Based on this, the present invention designs a mobile device that facilitates the measurement of joint range of motion to solve the above problems. Summary of the Invention

[0033] 1. In this invention, during the measurement of a patient's joint range of motion, medical staff can observe the swing angle of the shoulder joint swing arm on the second range of motion measuring disc to determine the vertical range of motion of the patient's shoulder joint. After the patient completes the vertical range of motion measurement, the angle locking bolt is loosened, and the first and second range of motion measuring discs are rotated in the transition groove via the multi-angle support. After the first and second range of motion measuring discs rotate 90 degrees, the second range of motion measuring disc is pressed down, and the second range of motion measuring disc flips through the spring hinge. During the process of the inner liner box being snapped into the outer liner box, the elastic snap-fit ​​shaft will snap into the snap-fit ​​interface, thus completing the stability of the first range of motion measuring disc after adjustment. At this time, the patient can swing their shoulder joint on the first range of motion measuring disc in a horizontal state.

[0034] 2. In this invention, twisting the angle locking bolt pushes the multi-angle support seat. As the pressure between the angle locking bolt and the multi-angle support seat gradually increases, pressure will appear between the telescopic shaft and the assembly port and gradually increase. The telescopic shaft will gradually retract into the telescopic groove until it is completely separated from the assembly port, thereby allowing the first and second range of motion measuring discs to be removed from the transfer groove. After removal, the first and second range of motion measuring discs, in conjunction with the shoulder joint swing device, can measure the range of motion of the leg joint. The first and second range of motion measuring discs, in conjunction with the shoulder joint swing device, make the application range wide, the flexibility high, the practicality strong, and have the technical effect of multi-purpose use.

[0035] 3. In this invention, the heights of the first and second range of motion measuring discs are adjusted according to the patient's height. After adjustment, the positioning suction cup is aligned with the patient's shoulder joint. The height locking bolt is loosened to release the contact between the height locking bolt and the inner support shaft. Then, the inner support shaft is moved in the outer support sleeve according to the patient's height to complete the height positioning of the first and second range of motion measuring discs. After that, the height locking bolt is turned again until its end is tightly abutted against the inner support shaft to ensure the stability of the first and second range of motion measuring discs after height positioning.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Please see Figures 1-8 The present invention provides a technical solution: a mobile device for measuring joint range of motion, comprising a multi-angle support assembly 1, the multi-angle support assembly 1 comprising a multi-angle support base 105 that rotates within a 90-degree range, a joint range of motion measuring assembly 2 connected to the side of the multi-angle support base 105, the joint range of motion measuring assembly 2 comprising a first range of motion measuring disc 201, a second range of motion measuring disc 203, a positioning suction cup 204 and a shoulder joint swing device 205, the first range of motion measuring disc 201 being connected to the multi-angle support base 105 and rotating within a 90-degree range, the second range of motion measuring disc 203 being hinged to the first range of motion measuring disc 201 via a spring hinge, a range of motion rotating shaft 202 being rotatably connected to the side of the first range of motion measuring disc 201, and a positioning suction cup 204 being connected to the side of the range of motion rotating shaft 202;

[0048] A shoulder joint swing device 205, which can be adapted to the length of an arm, is connected to the axis of the range of motion 202.

[0049] Specifically, the multi-angle support component 1 includes a movable base 101, an outer support sleeve 102 connected to the movable base 101, and an inner support shaft 103 sleeved inside the opening of the outer support sleeve 102.

[0050] The outer support sleeve 102 has a threaded hole No. 1 near the opening of the sleeve. A height locking bolt 104 is threaded into the threaded hole No. 1. The end of the height locking bolt 104 abuts against the inner support shaft 103. The top of the inner support shaft 103 has a transition groove. The multi-angle support seat 105 rotates within a 90-degree range in the transition groove.

[0051] The multi-angle support 105 has a telescopic groove on its side. A telescopic shaft is fitted inside the groove. One end of the telescopic shaft is connected to a telescopic spring. The telescopic shaft is elastically connected to the inside of the telescopic groove through the telescopic spring. An assembly port is opened in the transition groove corresponding to the telescopic shaft. The other end of the telescopic shaft is rotatably connected to the assembly port.

[0052] The specific implementation method is as follows: The multi-angle support seat 105 is fastened into the adapter groove by pressing. During the pressing process, the inner support shaft 103 and the telescopic shaft will be squeezed. Under the action of the squeezing force, the telescopic shaft retracts into the telescopic groove and squeezes the telescopic spring to cause elastic deformation. When the multi-angle support seat 105 is pressed down to the bottom of the adapter groove, the telescopic shaft is inserted into the assembly port under the action of the return elastic force of the telescopic spring. The first motion measuring plate 201 and the second motion measuring plate 203 are assembled with the adapter groove through the multi-angle support seat 105. The angle locking bolt 106 is twisted, and the end of the angle locking bolt 106 abuts against the multi-angle support seat. On 105, the stability of the multi-angle support 105 within the adapter groove is ensured. The angle locking bolt 106 is then continuously turned, pushing the multi-angle support 105. As the pressure between the angle locking bolt 106 and the multi-angle support 105 gradually increases, pressure will appear between the telescopic shaft and the assembly port, gradually increasing. The telescopic shaft will gradually retract into the telescopic groove until it is completely disengaged from the assembly port, thus allowing the first and second range of motion measuring discs 201 and 203 to be removed from the adapter groove. After removal, the first and second range of motion measuring discs 201 and 203, in conjunction with the shoulder joint swing device 205, can measure the range of motion of the leg joint.

[0053] Specifically, a second threaded hole is provided on the inner support shaft 103 at the position corresponding to the adapter groove. An angle locking bolt 106 is internally threaded into the second threaded hole. The end of the angle locking bolt 106 abuts against the multi-angle support seat 105 to improve the stability of the multi-angle support seat 105. Twisting the angle locking bolt 106 pushes the multi-angle support seat 105 to complete the disassembly of the multi-angle support seat 105. The shoulder joint swing device 205 includes a shoulder joint swing main arm 2051. One end of the shoulder joint swing main arm 2051 is connected to the shaft surface of the mobility shaft 202. The other end of the shoulder joint swing main arm 2051 is sleeved with a shoulder joint swing auxiliary arm 2052. The other end of the shoulder joint swing auxiliary arm 2052 is connected to a handle 2053.

[0054] The main arm 2051 of the shoulder joint swing is provided with a No. 3 threaded hole, and a length locking bolt is connected to the internal thread of the No. 3 threaded hole. The end of the length locking bolt abuts against the secondary arm 2052 of the shoulder joint swing.

[0055] The specific implementation method is as follows: Adjust the shoulder joint swing device 205 according to the length of the patient's arm, loosen the length locking bolt, and make the shoulder joint swing auxiliary arm 2052 perform corresponding extension and retraction movements within the shoulder joint swing main arm 2051 according to the length of the patient's arm. By adjusting the extension and retraction degree of the shoulder joint swing auxiliary arm 2052 within the shoulder joint swing main arm 2051, the combined length of the shoulder joint swing main arm 2051 and the shoulder joint swing auxiliary arm 2052 is adapted to the length of the patient's arm. After the adjustment is completed, twist the length locking bolt again to ensure the stability of the adjusted shoulder joint swing auxiliary arm 2052 within the shoulder joint swing main arm 2051. After the adjustment operation is completed, first make the positioning suction cup 204 attach to the patient's shoulder joint. Then, the patient holds the handle 2053 and makes a swinging motion. During the joint range of motion measurement, medical staff can observe the swing angle of the shoulder joint swing auxiliary arm 2052 on the second range of motion measuring plate 203.

[0056] Specifically, a horizontal angle support assembly 4 is provided between the first range of motion measuring disc 201 and the inner support shaft 103. The horizontal angle support assembly 4 includes an inner liner 401, which is connected to the first range of motion measuring disc 201. A threaded connecting sleeve 402 is threadedly connected to the inner liner 401, and a threaded connecting shaft 403 is threadedly connected to the inner threaded connecting sleeve 402. The other end of the threaded connecting shaft 403 extends into the inner liner 401. An outer liner 404 is provided on the inner support shaft 103 away from the first range of motion measuring disc 201. A bend bracket 405 is connected to the lower part of the outer liner 404, and the other end of the bend bracket 405 is connected to the axial surface of the inner support shaft 103. The inner liner 401 and the outer liner 404 are connected to each other. Multiple elastic fastening components 5 are provided between bushing boxes 404. The elastic fastening components 5 include a first adapter frame 501, which is connected to the axial surface of the threaded connecting shaft 403. An inner adapter shaft 502 is rotatably connected to the inner side of the first adapter frame 501. A serial interface is provided inside the inner bushing box 401 at the position corresponding to the inner adapter shaft 502. A second adapter frame 503 is sleeved in the serial interface. The other end of the inner adapter shaft 502 is rotatably connected to the end of the second adapter frame 503 that is close to it. A pressure relief groove is provided at the other end of the second adapter frame 503. A pressure relief shaft 504 is sleeved in the groove. A pressure relief spring is connected to one end of the pressure relief shaft 504. The pressure relief shaft 504 is elastically connected to the inside of the pressure relief groove through the pressure relief spring.

[0057] The other end of the pressure-relieving shaft 504 is provided with a spherical groove, and an elastic fastening shaft 505 is sleeved in the spherical groove. The outer liner box 404 is provided with a fastening interface corresponding to the position of the elastic fastening shaft 505. The elastic fastening shaft 505 is engaged in the fastening interface to lift the inner liner box 401 and stabilize it inside the outer liner box 404.

[0058] The specific implementation method is as follows: After the patient completes the vertical range of motion measurement operation, first loosen the angle locking bolt 106, and then rotate the first range of motion measuring disc 201 and the second range of motion measuring disc 203 in the transfer groove through the multi-angle support 105. After the first range of motion measuring disc 201 and the second range of motion measuring disc 203 rotate 90 degrees, press down the second range of motion measuring disc 203. The second range of motion measuring disc 203 flips over through the spring hinge. During the process of the inner liner box 401 being snapped into the outer liner box 404, the elastic snap-fit ​​shaft 505 will snap into the snap-fit ​​interface, thus completing the stability of the first range of motion measuring disc 201 after adjustment.

[0059] Working principle and usage:

[0060] Adjust the height of the first range of motion measuring disc 201 and the second range of motion measuring disc 203 according to the patient's height. After the adjustment is completed, align the positioning suction cup 204 with the patient's shoulder joint, loosen the height locking bolt 104 to release the contact between the height locking bolt 104 and the inner support shaft 103, and then make the inner support shaft 103 perform corresponding extension and retraction movements within the outer support sleeve 102 according to the patient's height. After completing the height positioning of the first range of motion measuring disc 201 and the second range of motion measuring disc 203, twist the height locking bolt 104 again until its end is tightly abutted against the inner support shaft 103 to ensure the stability of the first range of motion measuring disc 201 and the second range of motion measuring disc 203 after the height positioning is completed.

[0061] The multi-angle support 105 is fastened into the adapter groove by pressing. During the pressing process, the inner support shaft 103 and the telescopic shaft are squeezed together. Under the action of the squeezing force, the telescopic shaft retracts into the telescopic groove and squeezes the telescopic spring to cause elastic deformation. When the multi-angle support 105 is pressed down to the bottom of the adapter groove, the telescopic shaft is engaged into the assembly port under the action of the return force of the telescopic spring. The first and second motion measuring discs 201 and 203 are assembled with the adapter groove through the multi-angle support 105. Twisting the angle locking bolt 106 causes the end of the angle locking bolt 106 to abut against the multi-angle support 105, ensuring the stability of the multi-angle support 105 in the adapter groove. Continue to twist the angle locking bolt 106. 06. Angle locking bolt 106 pushes multi-angle support seat 105. As the extrusion pressure between angle locking bolt 106 and multi-angle support seat 105 gradually increases, the extrusion pressure between telescopic shaft and assembly port will gradually increase. The telescopic shaft will gradually retract into the telescopic groove until it is completely separated from the assembly port. Thus, the first range of motion measuring disc 201 and the second range of motion measuring disc 203 can be removed from the transfer groove. After being removed, the first range of motion measuring disc 201 and the second range of motion measuring disc 203, together with the shoulder joint swing device 205, can measure the range of motion of the leg joint. The first range of motion measuring disc 201 and the second range of motion measuring disc 203, together with the shoulder joint swing device 205, make the application range wide, the flexibility high, the practicality strong, and have the technical effect of one item serving multiple purposes.

[0062] Adjust the shoulder joint swing device 205 according to the length of the patient's arm, loosen the length locking bolt, and make the shoulder joint swing auxiliary arm 2052 perform corresponding extension and retraction movements within the shoulder joint swing main arm 2051 according to the length of the patient's arm. By adjusting the extension and retraction of the shoulder joint swing auxiliary arm 2052 within the shoulder joint swing main arm 2051, the combined length of the shoulder joint swing main arm 2051 and the shoulder joint swing auxiliary arm 2052 is adapted to the length of the patient's arm. After the adjustment is completed, twist the length locking bolt again to ensure the stability of the adjusted shoulder joint swing auxiliary arm 2052 within the shoulder joint swing main arm 2051. After the adjustment operation is completed, first make the positioning suction cup 204 attach to the patient's shoulder joint. Then, the patient holds the handle 2053 and makes a swinging motion. During the joint range of motion measurement, medical staff can observe the swing angle of the shoulder joint swing auxiliary arm 2052 on the second range of motion measuring plate 203 to obtain the vertical range of motion of the patient's shoulder joint.

[0063] After the patient completes the vertical range of motion measurement, first loosen the angle locking bolt 106, then rotate the first range of motion measuring disc 201 and the second range of motion measuring disc 203 in the transition groove via the multi-angle support 105. After the first and second range of motion measuring discs 201 and 203 rotate 90 degrees, press down on the second range of motion measuring disc 203. The second range of motion measuring disc 203 flips over via the spring hinge. During the process of the inner liner box 401 being snapped into the outer liner box 404, the elastic snap-fit ​​shaft 505 will snap into the snap-fit ​​interface, thus completing the stability of the first range of motion measuring disc 201 after adjustment. At this time, the patient can swing their shoulder joint on the first range of motion measuring disc 201 in a horizontal position.
