AI Technical Summary
The existing lymphedema arm circumference measuring instrument needs to move the arm horizontally 90 degrees during measurement to achieve a vertical state, resulting in intense pain when the lymphedema arm moves on a large scale, and the direction of the plate cannot be adjusted according to the arm position, resulting in inconvenience and potential damage.
A lymphedema arm circumference measuring instrument after breast cancer surgery is designed, using a combination of a tie rod, spring, friction plate, rotation shaft and turntable. By pulling the pull rod, the friction plate is driven to move the friction plate. The friction plate compresses the spring and leaves the rotation shaft and turntable, so that the measuring tape and limit plate are automatically adjusted to a position perpendicular to the arm, reducing the distance of the arm movement.
It realizes that the patient does not need to move his arms on a large scale during the measurement process, which reduces pain, improves the convenience and safety of measurement, avoids harm to the user, and is easy to use.

[0021] The adjusting device 4 includes a pull rod 401, a spring 402, a friction plate 403, a rotating shaft 404 and a rotating disk 405. The middle of the pull rod 401 is slidably connected to the support frame 3. The spring 402 is sleeved on the left side of the outer wall of the pull rod 401. The elastic coefficient of the spring 402 is 10-30N / cm. The two ends of the spring 402 are respectively fixed to the support frame 3 and the friction plate 403. When the friction plate 403 moves to the right, it will squeeze the spring 402. When the friction plate 403 is in a compressed state, one side of the friction plate 403 is fixed to the pull rod 401, and the other side of the friction plate 403 is tightly fitted with the rotating shaft 404. The friction plate 403 is used to limit the rotation of the rotating shaft 404. The outer wall of the rotating shaft 404 is rotatably connected to the support frame 3 through a bearing. The top of the rotating shaft 404 is fixed with a rotating disk 405, and the rotating shaft 404 drives the rotating disk 405 to rotate.
[0022] Pull the pull rod 401 to the right, the pull rod 401 drives the friction plate 403 to move, the friction plate 403 compresses the spring 402, and the friction plate 403 disengages from the rotating shaft 404. At this time, the rotating shaft 404 is rotated, the rotating shaft 404 drives the turntable 405 to rotate, and the turntable 405 drives the measuring tape 7 and the limit plate 6 to rotate, so that the measuring tape 7 and the limit plate 6 are rotated to a position perpendicular to the patient's arm, so that the patient does not need to move his arm in a large range, making the measurement more convenient, without causing harm to the user, and easy to use.
[0023] The right side of the top of the turntable 405 is fixedly connected to a limit plate 6, and the turntable 405 drives the limit plate 6 to move.

[0024] Working principle:
[0025] When using the breast cancer postoperative lymphedema arm circumference measuring instrument, first, the user connects the placement plate 1 to the bed frame through the electromagnet 5, so that the top of the placement plate 1 is on the same horizontal line with the bed, and then moves the patient's arm horizontally, and moves the support frame 3 back and forth, the support frame 3 drives the entire adjustment device 4 to move, and stops after the patient's arm contacts the turntable 405. In this way, the movement distance of the patient's arm is shorter, and at this time, the pull rod 401 is pulled to the right, the pull rod 401 drives the friction plate 403 to move, the friction plate 403 will compress the spring 402, and at the same time, the friction plate 403 is separated from the rotating shaft 404, and at this time, the rotating shaft 404 is rotated, the rotating shaft 404 drives the turntable 405 to rotate, and the turntable 405 drives the measuring tape 7 and the limit plate 6 to rotate, so that the measuring tape 7 and the limit plate 6 are rotated to a position perpendicular to the patient's arm, so that the patient does not need to move his arm in a large range, making the measurement more convenient, without causing harm to the user, and easy to use, completing the use of this device.
[0026] Example 2: Please refer to Figure 1-5 In this embodiment: an arm circumference measuring instrument for lymphedema after breast cancer surgery, wherein the outer wall of the slider 9 is also provided with an adjusting device 4, the adjusting device 4 includes a sleeve 4A1 and an extension rod 4A2, the inner wall of the sleeve 4A1 is slidably connected to the outer wall of the slider 9, and the sleeve 4A1 is sleeved on the slider 9, so that when the sleeve 4A1 rotates, the slider 9 drives the rotating shaft 404 to rotate, and the right side of the outer wall of the sleeve 4A1 is fixedly connected with the extension rod 4A2, and the extension rod 4A2 drives the sleeve 4A1 to rotate.
[0027] Working principle:
[0028] When this embodiment is working, the user puts the sleeve 4A1 on the slider 9 and then rotates the extension rod 4A2. The extension rod 4A2 drives the sleeve 4A1 to rotate. The sleeve 4A1 drives the rotating shaft 404 to rotate through the slider 9. The length of the extension rod 4A2 makes it more convenient and labor-saving to rotate the rotating shaft 404, thereby completing the use of this device.
