Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a medical shoulder joint rehabilitation training device. Background Technology

[0002] With the diversification of modern lifestyles and sports patterns, the incidence of shoulder joint injuries has shown a significant upward trend. Whether it is shoulder strain or contusion injuries suffered by athletes during high-intensity training and competition, or shoulder problems caused by daily activities (such as lifting heavy objects or prolonged desk work) in the general population, these injuries have brought great inconvenience to patients' lives and work. In order to improve the efficiency of treatment and recovery, shoulder joint rehabilitation training devices are usually needed in the process of treating shoulder joint injuries.

[0003] Common shoulder joint rehabilitation training devices are usually equipped with a chair and connect the patient's arm to the device. By having the patient slowly rotate their arm, the joint connecting the arm and shoulder is exercised, thereby achieving the effect of training and rehabilitation.

[0004] Considering that patients' heights vary when seated, causing relative changes in shoulder joint position, common shoulder joint rehabilitation training devices typically adjust height in two ways. The first method requires staff to manually release the fixation and then lift the device to adjust its height, which is both laborious and inconvenient. The second method uses a threaded rod to adjust the height by rotating it. However, when adjusting a larger height, the number of rotations required by the staff is high, resulting in low adjustment efficiency and affecting the overall usability of the device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a medical shoulder joint rehabilitation training device that solves the problem of low height adjustment efficiency in common shoulder joint rehabilitation training devices, which affects their overall usability.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A medical shoulder joint rehabilitation training device includes a seat body and a counterweight mechanism. A support is fixedly connected to the bottom of the seat body, and a training mechanism is provided on the seat body. The training mechanism provides a rotation fulcrum for the patient's arm and shoulder joint, and trains the patient's shoulder joint by rotation. The training mechanism includes an L-shaped frame, a training board rotatably connected to the bottom of the L-shaped frame, a handle fixedly connected to the inner wall of the training board, and an adjustment mechanism on the L-shaped frame. The adjustment mechanism has two adjustment methods, and the appropriate method can be selected according to the adjustment distance to quickly adjust the height of the training mechanism. The L-shaped frame is equipped with a lubrication mechanism that automatically lubricates the threaded rod A, reducing the friction between the threaded rod A and the threaded sleeve and improving the service life of the adjustment mechanism.

[0007] Preferably, the adjustment mechanism includes a threaded rod A, a threaded sleeve threadedly connected to the outer wall of the threaded rod A, a support rod fixedly connected to the outer wall of the seat body, a ramp block A fixedly connected to the top of the threaded sleeve, a ramp block B fixedly connected to the bottom of the threaded sleeve, a threaded rod B threadedly connected to the bottom of the support rod, a concave plate rotatably connected to the top of the threaded rod B, a pressing block A fixedly connected to the top of the concave plate, and a pressing block B fixedly connected to the bottom of the concave plate.

[0008] Preferably, the two ends of the threaded rod A are rotatably connected to the inner wall of the L-shaped frame, and the outer wall of the threaded sleeve is slidably connected to the inner wall of the support rod.

[0009] Preferably, the outer wall of the concave plate is slidably connected to the inner wall of the support rod, the bottom of the extrusion block A is adapted to the top of the inclined block A, and the top of the extrusion block B is adapted to the bottom of the inclined block B.

[0010] Preferably, the lubrication mechanism includes a cylinder, a control valve is fixedly connected to the bottom of the cylinder, a drain pipe is fixedly connected to the bottom of the control valve, a ring is fixedly connected to the top of the inner wall of the L-shaped frame, a through hole is opened on the ring, a soft brush is fixedly connected through the inner wall of the through hole, an infrared transmitter is fixedly connected to the outer wall of the threaded rod A, and an infrared receiver is fixedly connected to the inner wall of the L-shaped frame.

[0011] Preferably, the bottom of the cylinder is fixedly connected to the top of the L-shaped frame, and the bottom of the drain pipe passes through the outer wall of the L-shaped frame and is fixedly connected to the outer wall of the ring.

[0012] Preferably, the counterweight mechanism includes a fixed frame, a guide wheel rotatably connected to the inner wall of the fixed frame, a counterweight plate slidably connected to the inner wall of the fixed frame, and a traction rope penetrating and slidably connected to the outer wall of the guide wheel.

[0013] Preferably, the top end of the traction rope is fixedly connected to the bottom of the training board, and the bottom end of the traction rope is fixedly connected to the top of the counterweight plate.

[0014] Preferably, a counterweight block is inserted into the inner wall of the counterweight plate.

[0015] The application of a medical shoulder joint rehabilitation training device involves applying the aforementioned medical shoulder joint rehabilitation training device to the field of medical devices, particularly the field of medical rehabilitation training devices.

[0016] This invention provides a medical shoulder joint rehabilitation training device. It has the following beneficial effects: 1. This invention solves the problem of inconvenient height adjustment in common shoulder joint rehabilitation training devices through an innovative adjustment mechanism design. The adjustment mechanism has two adjustment methods: when a large adjustment is needed, the connection between the threaded sleeve and the threaded rod A can be quickly released or restored by rotating the threaded rod B, allowing for rapid movement of the threaded rod A to adjust the height of the training device—a convenient and labor-saving operation; when precise height adjustment is required, the threaded rod A can be directly rotated for fine-tuning. This design allows for selection of the appropriate adjustment method based on actual conditions, improving adjustment efficiency and accuracy, and overcoming the shortcomings of traditional manual handling being laborious and the low efficiency of adjusting with a single threaded rod.

[0017] 2. This invention incorporates a lubrication mechanism, which improves the service life of the adjustment mechanism. During the use of the training device, when the threaded rod A rotates, the infrared transmitter and receiver work together to control the valve to open according to the received signal. This allows the lubricating oil in the cylinder to flow through the drain pipe to the ring body. The lubricating oil is then applied to the outer wall of the threaded rod A by a soft brush, and gravity allows the lubricating oil to flow and cover the surface. This effectively reduces the friction between the threaded rod A and the threaded sleeve, reduces wear, ensures the long-term stable operation of the adjustment mechanism, and lowers equipment maintenance costs.

[0018] 3. This invention is equipped with a counterweight mechanism, which allows for adjustment of training intensity based on the patient's actual rehabilitation progress. By inserting different numbers of counterweights into the counterweight plate, the weight on the traction rope is altered, thereby adjusting the resistance the patient needs to overcome during shoulder joint rehabilitation training. This personalized design better meets the training needs of different patients at different stages of rehabilitation, improves the effectiveness of rehabilitation training, and contributes to the recovery of shoulder joint function.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example

[0023] Please see the appendix Figure 1 - Appendix Figure 8This invention provides a medical shoulder joint rehabilitation training device, including a seat body 1 and a counterweight mechanism 3. A support 2 is fixedly connected to the bottom of the seat body 1, and bolts are used to connect and fix it to the ground, thus securing the seat body 1 and ensuring stability during use. A training mechanism 4 is provided on the seat body 1, including an L-shaped frame 401. A training plate 402 is rotatably connected to the bottom of the L-shaped frame 401, allowing the training plate 402 to rotate along the outer wall of the L-shaped frame 401, thereby exercising the shoulder joint. A handle 403 is fixedly connected to the inner wall of the training plate 402, allowing the operator to rotate the training plate 402 by gripping the handle 403. An adjustment mechanism 5 is provided on the L-shaped frame 401, including a threaded rod A501, with both ends of the threaded rod A501 connected to the L-shaped frame 401. The inner wall is rotated, causing the threaded rod A501 to drive the L-shaped frame 401 to move vertically. The outer wall of the threaded rod A501 is threadedly connected to a threaded sleeve 503, causing the threaded rod A501 to move vertically along the inner wall of the threaded sleeve 503. The outer wall of the seat body 1 is fixedly connected to a support rod 502, so that the seat body 1 provides support and fixation for the support rod 502. The outer wall of the threaded sleeve 503 is slidably connected to the inner wall of the support rod 502, and the threaded sleeve 503 is composed of two sets of semi-rings, causing the outer wall of the threaded sleeve 503 to move laterally along the inner wall of the support rod 502. The top of the threaded sleeve 503 is fixedly connected to an inclined block A506, and the bottom of the threaded sleeve 503 is fixedly connected to an inclined block B505, causing the inclined blocks A506 and B505 to drive the threaded sleeve 503 to move laterally, so that the two sets of threaded sleeves 503 can close inward or unfold outward.

[0024] Specifically, such as Figure 4 , 5 As shown, a threaded rod B507 is threadedly connected to the bottom of the support rod 502, allowing the threaded rod B507 to rotate along the bottom of the support rod 502. A concave plate 504 is rotatably connected to the top of the threaded rod B507, causing the threaded rod B507 to rotate and drive the concave plate 504 to move vertically along the inner wall of the support rod 502. The outer wall of the concave plate 504 is slidably connected to the inner wall of the support rod 502, maintaining the stability of the vertical movement of the concave plate 504. An extrusion block A508 is fixedly connected to the top, and an extrusion block B509 is fixedly connected to the bottom of the concave plate 504. When the concave plate 504 moves vertically, it drives the extrusion blocks A508 and B509 to move vertically at the same time. The bottom of the extrusion block A508 is matched with the top of the inclined block A506, and the top of the extrusion block B509 is matched with the bottom of the inclined block B505, so as to achieve the effect of extruding and controlling the position of the inclined blocks A506 and B505.

[0025] like Figure 3 , 7As shown, a lubrication mechanism 6 is provided on the L-shaped frame 401. The lubrication mechanism 6 includes a cylinder 602, the bottom of which is fixedly connected to the top of the L-shaped frame 401, so that the L-shaped frame 401 provides a fixing effect for the cylinder 602. A control valve 603 is fixedly connected to the bottom of the cylinder 602. The control valve 603 receives signals from the infrared receiver 601. At the same time, a threshold value is preset by the operator, such as 20. When the infrared receiver 601 receives the signal from the infrared transmitter 606 for the 20th time, the control valve 603 receives the information and opens, allowing lubricating oil to be discharged outward along the inner wall of the cylinder 602. A discharge valve is fixedly connected to the bottom of the control valve 603. The liquid pipe 604 serves as a liquid transfer tube. The top of the inner wall of the L-shaped frame 401 is fixedly connected to the ring 605, providing a fixation effect for the ring 605. The ring 605 has a through hole, and a soft brush is fixedly connected through and fixedly connected to the inner wall of the through hole, allowing the lubricating oil in the ring 605 to be discharged outward along the soft brush. The bottom of the drain pipe 604 passes through the outer wall of the L-shaped frame 401 and is fixedly connected to the outer wall of the ring 605. An infrared transmitter 606 is fixedly connected to the outer wall of the threaded rod A501, and an infrared receiver 601 is fixedly connected to the inner wall of the L-shaped frame 401, so that the rotation of the threaded rod A501 automatically opens the control valve 603 for lubrication.

[0026] like Figure 8 As shown, the counterweight mechanism 3 includes a fixed frame 301. A guide wheel 302 is rotatably connected to the inner wall of the fixed frame 301 to provide guidance for the traction rope 303. A counterweight plate 304 is slidably connected to the inner wall of the fixed frame 301, allowing the counterweight plate 304 to move vertically along the inner wall of the fixed frame 301. A counterweight block 305 is inserted into the inner wall of the counterweight plate 304. By inserting the counterweight block 305, the weight of the counterweight plate 304 can be adjusted to suit patients with different levels of rehabilitation. The traction rope 303 is slidably connected through the outer wall of the guide wheel 302. The top end of the traction rope 303 is fixedly connected to the bottom of the training board 402, and the bottom end of the traction rope 303 is fixedly connected to the top of the counterweight plate 304. During the rotation of the training board 402, the traction rope 303 drives the counterweight plate 304 to move vertically, thereby achieving the purpose of rehabilitation training.

[0027] Working principle: When shoulder joint rehabilitation training is required, the user sits on the chair body 1, places their arms on the inner wall of the training board 402, and holds the handles provided on the training board 402. At the same time, medical staff can adjust the distance according to the patient's height. When the distance is large, the staff first rotates the threaded rod B 507 clockwise, causing the threaded rod B 507 to drive the concave plate to move vertically along the inner wall of the support rod. This causes the pressing block B 509 at the bottom of the concave plate 504 to move upward, so that the top of the pressing block B 509 presses against the bottom of the inclined block B 505. At the same time, the bottom of the pressing block A 508 separates from the top of the inclined block A 506, causing the inclined block B 505 to move outward under the pressure. This also causes the two sets of threaded sleeves to unfold outward, so that the threaded sleeves are disconnected from the threaded rod A 501.

[0028] The threaded rod A 501 is moved vertically by a rapid pull, causing the L-shaped frame 401 on the outer wall to move rapidly. After reaching the designated position, the threaded rod B 507 is rotated in the opposite direction, causing the concave plate to move the extrusion block B 509 downward, separating the extrusion block B 509 from the inclined block B 505. At the same time, the bottom of the extrusion block A 508 presses against the top of the inclined block A, causing the two sets of threaded sleeves to move inward, maintaining the threaded connection between the threaded sleeves and the threaded rod A 501, thus achieving the effect of rapid distance adjustment.

[0029] Meanwhile, by rotating the threaded rod A 501, the vertical position of the L-shaped frame 401 can be changed by rotating the threaded rod A 501 along the inner wall of the threaded sleeve. This ensures the accuracy of the adjustment position and also benefits the self-locking effect of the threaded rod A 501, making the adjustment process more effortless. Compared with existing adjustment methods, this device can select the appropriate adjustment method according to the actual situation on site for quick and accurate adjustment, thus improving the convenience of using the training device.

[0030] Simultaneously, a lubrication mechanism 6 is provided. When the threaded rod A501 rotates, the infrared transmitter at the bottom will compare with the infrared receiver. When the infrared receiver receives multiple signals from the infrared transmitter, the control valve will open, allowing the lubricating oil stored on the inner wall of the cylinder to be discharged downwards. The lubricating oil is then transferred along the inner wall of the drain pipe to the inner wall of the ring 605 and discharged through the through hole on the ring. The lubricating oil is then soaked into the soft brush set on the through hole. As the threaded rod A501 rotates, the lubricating oil on the soft brush is gradually coated on the outer wall. Using gravity, the lubricating oil flows downwards along the outer wall of the threaded rod A501, reducing the friction between the threaded rod A501 and the threaded sleeve, thereby improving the service life of the adjustment mechanism.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
