Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and in particular relates to a hand nerve rehabilitation training device based on targeted regulation. Background Technology

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are used directly or indirectly on the human body, including the necessary computer software. Medical devices include medical equipment and medical consumables. Hand nerve rehabilitation training devices are a type of medical device. The nerve supply to the hand mainly comes from the median, ulnar, and radial nerves. Because nerve damage not only causes sensory disturbances but also often affects the motor and sympathetic nerve functions of the hand, it has a significant impact on hand function. If not treated promptly, atrophy of the small muscles in the hand will affect the effectiveness of treatment. Therefore, it is crucial to detect and treat hand nerve injuries promptly. Among various rehabilitation methods, motor rehabilitation training is one of the most effective. Some patients complete rehabilitation training with the help of medical staff, while others use rehabilitation training equipment for assistance.

[0003] In the existing technology, the intensity of hand nerve rehabilitation training devices is generally not adjustable. Since the nerve damage of each patient is different, the required training intensity is also different, which leads to certain limitations in the use of existing devices and poor flexibility. Summary of the Invention

[0004] The purpose of this invention is to provide a hand nerve rehabilitation training device based on targeted regulation, which solves the problem of poor flexibility in existing devices.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a hand nerve rehabilitation training device based on targeted regulation, comprising a mounting frame, a base plate, and a movable frame. The base plate is mounted on the lower surface of the mounting frame, and fixing holes are provided at both ends of the upper surface of the base plate. A plurality of sliding rods are provided on the upper surface of the mounting frame, penetrating the upper surface of the mounting frame and slidingly engaging with the periphery of the sliding rods. A first limiting plate is mounted on one end of each sliding rod, and a second limiting plate is embedded in the other end of each sliding rod. The second limiting plate has a ring-shaped structure, and its inner surface slidesly engaging with the periphery of the sliding rod. A positioning hole is provided at the other end of each sliding rod, and a positioning rod is mounted on one surface of the second limiting plate. One end of the positioning rod penetrates the first surface of the second limiting plate and engages with the positioning hole, facilitating the removal of the second limiting plate and thus the sliding rods. This allows for easy adjustment of the training intensity of the device according to the nerve damage of each patient, avoiding limitations and improving the flexibility of the device. The movable frame is embedded in the other end of the sliding rod, and the upper surface of the second limiting plate engages with the inner top surface of the movable frame.

[0007] Furthermore, a connecting plate is also embedded on the periphery of the sliding rod. The connecting plate is a ring-shaped plate structure. The inner surface of the connecting plate slides with the sliding rod. The lower surface of the connecting plate cooperates with the upper surface of the mounting frame. A first return spring is installed between the upper surface of the connecting plate and the lower surface of the first limiting plate. The training effect is achieved by the reset and compression of the first return spring. The first return spring is wrapped around the periphery of the sliding rod.

[0008] Furthermore, several mounting plates are installed on the bottom surface inside the movable frame, and connecting rods are installed on the lower surface of each mounting plate. One end of each connecting rod penetrates the bottom surface inside the movable frame, and finger sleeves are installed on the lower surface of each connecting rod. The inner surface of each finger sleeve is fitted with a first protective soft pad to facilitate finger insertion and improve comfort.

[0009] Furthermore, guide rods are installed on the top surface inside the mounting frame, with two guide rods arranged opposite each other. Mounting blocks are installed on both opposite surfaces of the moving frame, and guide grooves are installed on one surface of each of the two mounting blocks.

[0010] Furthermore, one end of each of the two guide rods passes through a guide groove, and the peripheral surfaces of the two guide rods are slidably engaged with the two guide grooves respectively, which facilitates the sliding of the moving frame and ensures its stability during use. Sliding blocks are installed on the peripheral surfaces of both guide rods.

[0011] Furthermore, the two sliding blocks are slidably engaged with the peripheral surfaces of the two guide rods, and a connecting shaft is installed between the two sliding blocks. A second protective pad is embedded on the peripheral surface of the connecting shaft to improve comfort.

[0012] Furthermore, a second return spring is installed between the lower surface of each of the two sliding blocks and the upper surface of the base plate. The two second return springs are respectively wrapped around the periphery of the two guide rods. The compression and reset of the second return springs facilitate the rehabilitation training of the thumb.

[0013] Furthermore, the mounting frame has several insertion holes on both opposite surfaces, and insertion rods are installed inside the insertion holes. One end of the insertion rod is engaged with a sliding block to facilitate adjustment and fixation of the two sliding blocks, thereby facilitating adjustment of the position of the connecting shaft and making it easier to adjust according to the size of the patient's hand, further improving the flexibility of the device. A third limiting plate is installed on the other end of the insertion rod.

[0014] The present invention has the following beneficial effects:

[0015] 1. The present invention, through the positioning hole and positioning rod structure, facilitates the removal of the second limiting plate, thereby facilitating the removal of the sliding rod. This allows for easy adjustment of the training intensity of the device according to the nerve damage of each patient, avoiding limitations and improving the flexibility of the device.

[0016] 2. The present invention uses a rod and a hole structure to facilitate the adjustment of the position of the two sliding blocks, thereby facilitating the adjustment of the position of the connecting shaft and making it easier to adjust according to the size of the patient's palm, further improving the flexibility of the device.

[0017] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] Example 1:

[0029] Please see Figures 1-6As shown, this invention is a hand nerve rehabilitation training device based on targeted regulation, including a mounting frame 1, a base plate 13, and a movable frame 8. The base plate 13 is mounted on the lower surface of the mounting frame 1. Fixing holes 23 are provided at both ends of the upper surface of the base plate 13. A plurality of sliding rods 2 are provided on the upper surface of the mounting frame 1, penetrating the upper surface of the mounting frame 1. The peripheral surfaces of the sliding rods 2 slide against the mounting frame 1. A first limiting plate 3 is installed at one end of each sliding rod 2, and a second limiting plate 6 is embedded at the other end of each sliding rod 2. The second limiting plate 6 has a ring-shaped plate structure, and its inner surface slides against the peripheral surfaces of the sliding rods 2. A positioning hole is provided at the other end of each sliding rod 2. A positioning rod 7 is installed on one surface of the plate 6. One end of the positioning rod 7 passes through the second limiting plate 6 and engages with the positioning hole, making it easy to remove the second limiting plate 6 and thus the sliding rod 2. This allows for easy adjustment of the training intensity of the device according to the nerve damage of each patient, avoiding limitations and improving the flexibility of the device. The moving frame 8 is embedded in the other end of the sliding rod 2. The upper surface of the second limiting plate 6 and the inner top surface of the moving frame 8 cooperate with each other. Guide rods 14 are installed on the inner top surface of the mounting frame 1. The two guide rods 14 are arranged opposite to each other. Mounting blocks 15 are installed on the two opposite surfaces of the moving frame 8. Guide grooves 16 are installed on one surface of each of the two mounting blocks 15.

[0030] Several mounting plates 9 are installed on the bottom surface inside the movable frame 8. A connecting rod 10 is installed on the lower surface of each mounting plate 9. One end of each connecting rod 10 penetrates the bottom surface inside the movable frame 8. A finger sleeve 11 is installed on the lower surface of each connecting rod 10. A first protective soft pad 12 is embedded in the inner surface of each finger sleeve 11 to facilitate finger insertion and improve comfort.

[0031] One end of each of the two guide rods 14 passes through the guide groove 16, and the two guide rods 14 slide with the two guide grooves 16 respectively, which facilitates the sliding of the moving frame 8 and ensures its stability during use. Sliding blocks 17 are installed on the two guide rods 14.

[0032] Two sliding blocks 17 are slidably engaged with the two guide rods 14 on their circumferential sides, and a connecting shaft 18 is installed between the two sliding blocks 17. A second protective soft pad 24 is embedded on the circumferential side of the connecting shaft 18 to improve its comfort.

[0033] A second return spring 19 is installed between the lower surface of the two sliding blocks 17 and the upper surface of the base plate 13. The two second return springs 19 are respectively wrapped around the sides of the two guide rods 14. The compression and reset of the second return springs 19 facilitate the rehabilitation training of the thumb.

[0034] The mounting frame 1 has several insertion holes 20 on both opposite surfaces. Insert rods 21 are installed inside the insertion holes 20. One end of the insertion rod 21 is engaged with the sliding block 17 to facilitate adjustment and fixation of the positions of the two sliding blocks 17, thereby facilitating adjustment of the position of the connecting shaft 18. This allows for adjustment according to the size of the patient's hand, further improving the flexibility of the device. A third limiting plate 22 is installed at the other end of the insertion rod 21.

[0035] A connecting plate 4 is also installed on the side of the sliding rod 2. The connecting plate 4 is a ring-shaped plate structure. The inner surface of the connecting plate 4 slides with the sliding rod 2. The lower surface of the connecting plate 4 cooperates with the upper surface of the mounting frame 1. A first return spring 5 is installed between the upper surface of the connecting plate 4 and the lower surface of the first limiting plate 3. The training effect is achieved by the reset and compression of the first return spring 5. The first return spring 5 is wrapped around the side of the sliding rod 2.

[0036] Example 2:

[0037] Please see Figures 1-6 As shown, this invention is a hand nerve rehabilitation training device based on targeted regulation. Its usage is as follows: First, the base plate 13 and mounting frame 1 are fixed in a suitable position through the fixing hole 23. Then, the patient places the finger requiring rehabilitation training into the finger sleeve 11 and pulls it downwards. The first return spring 5's reset and compression achieve the training effect. The thumb grips the second protective pad 24. When the thumb does not require rehabilitation training, the insertion rod 21 is inserted into the insertion hole 20 to fix the sliding block 17. When the thumb needs rehabilitation training, the insertion rod 21 is removed. The second return spring 19's compression and reset facilitate thumb rehabilitation training. The positioning hole and positioning rod 7 structure facilitate the removal of the second limiting plate 6, thereby facilitating the removal of the sliding rod 2. This allows for adjustment of the device's training intensity according to each patient's nerve damage, avoiding limitations and improving the device's flexibility.
