Description

Technical Field

[0001] This application relates to the field of medical devices, and in particular to a shoulder joint limiting angle measuring device. Background Technology

[0002] Joint range of motion refers to the arc of motion or the angle of rotation that a joint can move. Measuring the range of motion is a basic step in assessing patients with muscular, skeletal, and nerve damage, and is one of the indicators for assessing the extent and degree of joint movement function impairment.

[0003] Its main purpose is to determine whether there is limited joint mobility and to identify the causes affecting joint mobility; to determine the degree of limited joint mobility; to determine appropriate treatment goals and assess the potential degree of recovery; to provide objective evidence for selecting appropriate treatment methods; to objectively measure the progress of joint range of motion to evaluate the effectiveness of rehabilitation treatment and training; to provide motivation for patients and therapists; and to provide objective data for scientific research. Currently, the method for measuring shoulder joint range of motion is to manually measure the patient's shoulder joint range of motion using a goniometer. This method is not only inconvenient for medical staff to accurately measure the range of motion, but also wastes manpower. Utility Model Content

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] This application discloses a shoulder joint limiting angle measuring device.

[0027] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A shoulder joint limiting angle measuring device includes a lifting assembly 1, an angle plate 2, an operating assembly 3, and a shoulder pressing block 4.

[0028] The lifting assembly 1 has a first electric telescopic rod 5 horizontally fixedly installed at its top, and a vertical rod 6 fixedly installed at its bottom. The bottom of the vertical rod 6 has a first T-shaped groove 61. A first T-shaped block 41 is fixedly installed at the top of the shoulder pressing block 4, and the first T-shaped block 41 is rotatably installed within the first T-shaped groove 61. A locking pin 62 is threaded onto the bottom of the vertical rod 6. Angle disc 2 is mounted on the lifting assembly 1 and located between the shoulder pressing block 4 and the lifting assembly 1. One end of the operating assembly 3 is located at the center of the angle disc 2 and is rotatably connected to it. It should be noted that the bottom of the shoulder pressing block 4 is directly opposite the center of the angle disc 2. The shoulder pressing block 4 is arc-shaped to facilitate the fixation of the shoulders of the person being measured, preventing the person from shrugging their shoulders during measurement and causing inaccurate measurements. Angle lines are engraved on the angle disc 2.

[0029] Since the weights of the people being tested vary, i.e., their shoulder widths vary, the first electric telescopic rod 5 is designed to facilitate the forward and backward movement of the shoulder pressing block 4, so that the shoulder pressing block 4 can fix the shoulders of the people being tested; the first T-shaped circular groove 61 and the first T-shaped circular block 41 are designed to facilitate the rotation of the shoulder pressing block 4, so that the shoulder pressing block 4 can fix shoulders at different angles; the locking pin 62 is designed to fix the first T-shaped circular block 41 to prevent the shoulder pressing block 4 from rotating during the testing of the people being tested.

[0030] The lifting assembly 1 includes a support tube 11, a lifting rod 12, and a second electric telescopic rod 13. The support tube 11 is placed vertically, the second electric telescopic rod 13 is fixedly installed on the inner wall of the support tube 11, the lifting rod 12 is fixedly installed on the top end of the second electric telescopic rod 13, the horizontal end of the L-shaped rod is fixedly installed on the top end of the lifting rod 12, and the angle plate 2 is vertically fixedly installed on the circumferential wall of the lifting rod 12 and is located between the shoulder block 4 and the lifting rod 12.

[0031] The staff adjusts the second electric telescopic rod 13 according to the height of the person to be tested. The second electric telescopic rod 13 drives the lifting rod 12 to rise or fall, which in turn drives the shoulder pressing block 4 to rise or fall until the shoulder pressing block 4 fixes the shoulder of the person to be tested.

[0032] The operating component 3 includes an operating lever 31, a rotating lever 32, and a return spring 33. One end of the operating lever 31 is rotatably mounted at the center of the angle disc 2, and the other end has a receiving groove 311. One end of the return spring 33 is fixedly connected to the bottom of the receiving groove 311, and the other end is fixedly mounted with a connecting block 331. The end of the connecting block 331 facing away from the return spring 33 has a second T-shaped circular groove 3311. One end of the rotating lever 32 is fixedly mounted with a second T-shaped circular block 321, which is rotatably mounted in the second T-shaped circular groove 3311. The other end of the rotating lever 32 is fixedly mounted with a handle 322. It should be noted that a baffle 312 is fixedly installed at the opening of the receiving groove 311 to prevent the connecting block 331 from sliding out of the receiving groove 311.

[0033] The person being tested can move the rotating rod 32 toward the outside of the receiving groove 311 according to their own arm length, and can also rotate the rotating rod 32 according to their own gripping habits, so that the person being tested can easily hold the handle 322.

[0034] A ring 8 is fixedly installed on the lifting rod 12 via a connecting rod 827. The ring 8 and the angle disk 2 are located on the same vertical plane, and the center of the ring 8 and the center of the angle disk 2 are the same. A first limiting groove 81 is provided on the inner wall of the ring 8, and a second limiting groove 21 is provided on the outer circumference of the angle disk 2. A limiting component 9 is installed on the operating rod 31.

[0035] The limiting assembly 9 includes a limiting rod 91, a first pulley 92, and a second pulley 93. The limiting rod 91 is fixedly installed on the operating rod 31 and is located between the ring 8 and the angle disk 2. The first pulley 92 and the second pulley 93 are respectively installed on both sides of the limiting rod 91. The first pulley 92 is slidably connected to the ring 8 through the first limiting groove 81, and the second pulley 93 is slidably connected to the angle disk 2 through the second limiting groove 21.

[0036] The limit component 9 is designed to prevent the operator from applying excessive force during measurement, which could deform the operating lever 31 and cause inaccurate measurements.

[0037] The implementation principle of a shoulder joint limiting angle measuring device in this application embodiment is as follows:

[0038] The person being tested faces the dial and adjusts the shoulder pressure block 4 up or down using the lifting component 1 until the shoulder pressure block 4 fixes one of the person's shoulders. Then, the person's arm with the fixed shoulder is straightened and the hand is gripping the handle 322. The arm is then rotated clockwise and counterclockwise, which allows the forward and backward extension angles of the person's arm to be measured.

[0039] The person being tested faces the dial and adjusts the shoulder pressure block 4 up or down using the lifting component 1 until the shoulder pressure block 4 fixes the other shoulder of the person being tested. Then the arm of the person being tested with the fixed shoulder is straightened and the hand is holding the handle 322. Then the arm is rotated clockwise and counterclockwise, so that the forward and backward extension angles of the other arm of the person being tested can be measured.

[0040] The person being tested faces the dial, rotates the shoulder pressure block 4 90° and tightens the locking pin 62. Then, adjust the rise or fall of the shoulder pressure block 4 through the lifting component 1 until the shoulder pressure block 4 fixes one of the shoulders of the person being tested. Then, the arm of the person being tested with the fixed shoulder is straightened and the hand is holding the handle 322. Then the arm is rotated clockwise (or counterclockwise) so that the abduction angle of the arm of the person being tested can be measured.

[0041] The person being tested faces the dial and adjusts the shoulder pressure block 4 up or down using the lifting component 1 until the shoulder pressure block 4 fixes the other shoulder of the person being tested. Then, the arm with the fixed shoulder of the person being tested is straightened and the hand is holding the handle 322. Then the arm is rotated counterclockwise (or clockwise) so that the abduction angle of the other arm of the person being tested can be measured.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
