Abstract
Description
Technical Field
[0001] This utility model relates to the field of stroke rehabilitation treatment technology, and in particular to a grip strength training rehabilitation device for stroke patients. Background Technology
[0002] For stroke patients with hemiplegia, the current approach is mainly to massage the affected side. However, this passive rehabilitation training has a long training cycle and poor results. Stroke patients need to actively clench their hands to rehabilitate their muscle strength. However, because they cannot control the intensity of their self-training, improper training methods and intensity can lead to the opposite of the desired effect. Therefore, grip strength rehabilitation training equipment is usually needed to assist patients in training their fingers to clench their fingers.
[0003] Stroke patients often have impaired hand dexterity and difficulty in controlling their movements. Existing grip strength training devices for stroke patients lack the ability to stabilize the patient's hand and have significant limitations. To address the shortcomings of existing technologies, we propose a grip strength training rehabilitation device for stroke patients. Utility Model Content

[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. In this utility model, the patient can perform hand grip training through the set grip frame. By pulling the grip frame, the grip frame drives the tension structure inside the mounting shell to move the palm. A sliding reset structure is installed between the sliding frame and the mounting base, so that the device can be used for a long time.
[0014] 2. In this utility model, the arm sleeve is designed to fix the position of the patient's arm, preventing the device from falling due to poor grip when held. At the same time, finger sleeves are installed inside the handle frame to fix the patient's fingers, making it easier for the patient to exert force and making the device more stable and secure. A hook is installed at the top of the device, which can suspend the device at a high place, so that the patient can train without holding the device, reducing the burden on the patient's hands.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] Example 1, as Figures 1-4 As shown, a grip strength training rehabilitation device for stroke patients is used for finger movement rehabilitation training. The patient grasps the outer frame 1 of the grip strengthener to pull the handle frame 5 inside the outer frame 1 for rehabilitation training. The patient holds the outer frame 1 and simultaneously inserts four fingers into four sets of finger sleeves 6 for fixation. By grasping the handle frame 5, the patient pulls the handle frame 5 downwards. The movable connecting block 7 at the top of the handle frame 5 is connected to the traction rod 4, allowing the grip frame 5 to pull the traction rod 4 via the movable connecting block 7. The traction rod 4 is connected to the sliding frame 15 inside the mounting housing 2, and the sliding frame 15 is slidably connected to the mounting base 12. When the user pulls the grip frame 5, the traction rod 4 can drive the sliding frame 15 to pull down. The sliding frame 15 slides longitudinally along the slide rail 18 on the surface of the mounting base 12. After completing one gripping motion, the sliding frame 15 can automatically reset. The reset spring 14 at the top of the sliding frame 15 is connected and fixed to the upper end abutment block 13 of the mounting base 12. When the sliding frame 15 is pulled down to a certain extent, the reset spring 14 can rebound, thereby resetting the sliding frame 15, so that the device can be used for a long time. At the same time, since patients usually have weak hand strength, the reset pulling structure of this device does not require too much force to pull, which is convenient for patients to exercise their hands.
[0022] Example 2, as Figures 1-4 As shown, a grip strength training rehabilitation device for stroke patients includes an arm sleeve 8 installed on the outer side of the grip strength device frame 1 to fix the position of the patient's arm. The arm sleeve 8 is tied to the patient's arm with a nylon strap 9 to prevent the device from falling due to a loose grip when the patient holds it. At the same time, the finger sleeves inside the grip frame 5 can fix the patient's fingers, which facilitates the patient's exertion process and makes the device more stable and secure. Two sets of hooks 11 are installed at the top of the device, which can hang the exercise device on the wall so that the patient can train without holding the device, reducing the burden on the patient's hands and making the device safer.
[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
