Abstract
Description
Technical Field
[0001] This utility model relates to the field of rehabilitation training equipment, specifically a postoperative finger exercise grip strength monitoring device. Background Technology
[0002] The radial artery first passes between the brachioradialis and pronator teres muscles, then descends between the brachioradialis tendon and the flexor carpi radialis tendon, circles the radial styloid process to the dorsum of the hand, passes through the first metacarpal space to the palm, and anastomoses with the deep palmar branch of the ulnar artery to form the deep palmar arch. After coronary intervention via the radial artery, prolonged mechanical compression of the wrist obstructs blood circulation in the hand and compresses local nerves, leading to pain, swelling, and numbness in the operated limb, reducing patient comfort. To improve postoperative recovery, patients need to strengthen their training. Grip strengtheners are fitness equipment used to enhance hand muscles and grip strength. Using grip strengtheners helps increase blood flow, promotes vasodilation, and strengthens the muscles of the fingers, wrist, and forearm. Currently, spring-type grip strengtheners on the market do not have counting and monitoring functions, and patients often cannot reach the standard grip extension force during grip training. Due to the lack of reminder functions, patients cannot achieve effective training. Utility Model Content
[0003] The purpose of this invention is to provide a postoperative finger exercise grip strength monitoring device to solve the problems mentioned in the background art, such as the lack of counting and monitoring functions in currently available spring-type grip strength devices, the inability of patients to reach the standard grip extension force during grip strength training, and the lack of reminder functions, which prevent patients from achieving effective training.

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) A counter is installed on one side of the top of the handle. The surface of the counter is equipped with a microcontroller display. When the patient is training, he holds the handle and presses the movable bar. When the movable bar moves closer to the handle, the inner contact block contacts the proximity sensor. The proximity sensor receives the signal and transmits it to the inside of the counter. At this time, the microcontroller display shows the number of grips and counts. At the same time, the indicator light on the surface of the counter will light up according to the counting standard. There are two sets of indicator lights. When the count is successful, the indicator light will emit a "green" light and the voice player will emit an encouraging voice. If the patient does not press hard enough during training, the count will fail. At this time, the indicator light will emit a "red" light to remind the patient that the force is not enough. This hand grip strength exercise device can monitor the patient's training through counting and help the patient achieve the training effect.
[0015] (2) With the provided adjustment component, an installation groove is provided at the middle of the top of the handle. The adjustment knob is installed inside the installation groove. The screw connected to one end of the movable rod is threaded onto the surface of the adjustment knob.

[0024] In practical use: A counter 41 is installed on the top side of the handle 1. The surface of the counter 41 is equipped with a microcontroller display 42. When the patient is training, he holds the handle 1 and presses the movable rod 3. When the movable rod 3 moves closer to the handle 1, the inner contact block 46 contacts the proximity sensor 45. The proximity sensor 45 receives the signal and transmits it to the inside of the counter 41. At this time, the microcontroller display 42 displays the number of grips and counts. At the same time, the indicator lights 43 on the surface of the counter 41 will light up according to the counting standard. There are two sets of indicator lights 43. When the count is successful, the indicator light 43 will emit a "green" light and the voice player 44 will emit an encouraging voice. If the patient does not press hard enough during training, the count will fail. At this time, the indicator light 43 will emit a "red" light to remind the patient that the force is not enough. This hand grip strength training device can monitor the patient's training through counting and monitoring to help the patient achieve the training effect.
[0025] Please see Figure 1 , Figure 4 The adjustment component 5 includes a mounting groove 51 opened at the middle of the top of the handle 1, an adjustment knob 52 is rotatably installed inside the mounting groove 51, and a screw 53 is installed on one end surface of the movable rod 3, with the adjustment knob 52 threadedly connected to the surface of the screw 53.
[0026] In practical use: The top center of the handle 1 has a mounting groove 51. The adjustment knob 52 is rotatably installed inside the mounting groove 51. The screw 53 connected to one end of the movable rod 3 is threaded onto the surface of the adjustment knob 52.
