Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically a protective structure for rehabilitation arms. Background Technology

[0002] Arm rehabilitation training is a series of restorative exercises designed to address limited or injured arm function. These exercises aim to improve arm muscle strength, joint flexibility, and coordination, thereby enhancing arm function.

[0003] The arm protection structure for rehabilitation includes fixation and support, protection mechanism, control and adjustment, etc. The fixation mechanism fixes the arm in the appropriate position, and the support mechanism provides stable support for the arm. When the arm is undergoing rehabilitation training, the protection mechanism begins to play its role.

[0004] Traditional rehabilitation arm protection structures often cannot be flexibly adjusted according to the patient's specific situation, resulting in limited rehabilitation effects; therefore, a rehabilitation arm protection structure is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, traditional rehabilitation arm protection structures often cannot be flexibly adjusted according to the patient's specific condition, resulting in limited rehabilitation effects. This invention proposes a rehabilitation arm protection structure.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A rehabilitation arm protection structure of this utility model includes an upper arm sleeve and a forearm sleeve; a sleeve is fixedly installed inside both the upper arm sleeve and the forearm sleeve; multiple through holes are arrayed on the sleeve, and an air chamber is fixedly installed in each through hole; one end of each air chamber penetrates the outer wall of the sleeve; multiple airbags are arrayed and fixedly installed on the air chamber inside the sleeve; an elbow pad is fixedly installed on one end of the upper arm sleeve; a connecting box is fixedly installed on one side of the upper arm sleeve; a slide rail is fixedly installed on one side of the forearm sleeve; a connecting plate is slidably installed in the slide rail; multiple slots are arrayed on one side of the connecting plate; one end of the connecting plate is rotatably installed inside the connecting box; an annular protrusion is formed in the middle of one end of the connecting plate; toothed grooves are arrayed on the outer periphery of the annular protrusion; an adjusting seat is fixedly installed inside the connecting box at one end of the connecting plate; a square hole is formed in one end of the adjusting seat. A control block is slidably installed inside the hole. The control block has teeth on one end near the connecting plate, which mesh with the toothed grooves on the connecting plate. A slide rod is fixedly installed on the other end of the control block. A circular hole is opened in the other end of the adjusting seat, and the other end of the slide rod is slidably disposed within the circular hole. A slider is slidably installed on the slide rod. An adjusting spring is fitted onto the slide rod between the slider and the control block. A connecting rod is rotatably installed on the upper part of the slider. A groove is opened in the upper part of the other end of the adjusting seat, and an installation block is slidably installed within the groove. A threaded hole is opened in the installation block, and the other end of the connecting rod is rotatably installed on the installation block. A mounting box is provided on one side of the connecting plate with a slot. A fixing block is slidably installed in the mounting box. A protrusion is opened on one side of the lower end of the fixing block, and the protrusion slides through the slide rail and is slidably disposed within the slot. Through the coordinated action of the control block, slide rod, slider, adjusting spring, and connecting plate, the force required for bending the arm is flexibly adjusted.

[0007] Preferably, an air tube is fixedly connected to the outside of the air chamber. The same end of the air tube passes through the upper arm sleeve and the lower arm sleeve respectively and is fixedly installed with a balloon. A control valve is set near the connection between the upper end of the air tube and the balloon. The air pressure in the air chamber can be manually or automatically adjusted by the balloon and the control valve, thereby changing the degree of inflation of the balloon. This improves the adjustability of the arm protection structure, allowing patients or medical staff to easily adjust the support strength of the balloon according to rehabilitation needs, thus enhancing the personalization and comfort of rehabilitation training.

[0008] Preferably, each of the air chambers is provided with a connecting pipe, and the two ends of the connecting pipe are respectively fixedly connected to the sides of two adjacent air chambers. By providing connecting pipes, all air chambers can be interconnected to form a unified air pressure system, which enhances the uniformity and stability of the airbag and avoids problems such as poor rehabilitation effect or patient discomfort caused by uneven air pressure.

[0009] Preferably, a lead screw is provided inside the sliding groove of the adjustment seat. One end of the lead screw is rotatably installed in the adjustment seat, and the other end is rotatably installed in the connecting box. A knob is fixedly installed through the connecting box. The mounting block is slidably installed on the lead screw. By rotating the knob, the lead screw is driven to rotate, thereby causing the mounting block to slide in the sliding groove. The position adjustment of the mounting block can indirectly affect the position of the connecting plate and the fixing block, thereby achieving precise adjustment of the arm protection structure. This provides a more precise and convenient adjustment method, allowing patients or medical staff to make personalized adjustments according to the patient's specific situation, improving the pertinence and effectiveness of rehabilitation training.

[0010] Preferably, the other side of the lower end of the fixing block is wedge-shaped, and a push block is vertically arranged on one side of the lower end of the fixing block and slidably installed in the lower end of the mounting box. One end of the push block is located at the bottom of the wedge-shaped surface of the fixing block, and the other end penetrates through the mounting box. The combination of the wedge design and the push block allows the user to easily adjust the position of the fixing block by pushing the push block, which simplifies the adjustment process of the fixing block and improves the convenience and efficiency of operation.

[0011] Preferably, the top of the mounting box has a mounting hole, in which a limiting rod is slidably installed. The lower end of the limiting rod is fixedly connected to the top of the fixing block. A return spring is provided in the upper end of the mounting box and is fitted onto the limiting rod. By setting the limiting rod and the return spring, the fixing block is provided with an automatic reset function, which enhances the stability and reliability of the arm protection structure and avoids problems such as poor rehabilitation effect or patient discomfort caused by improper positioning of the fixing block.

[0012] The advantages of this utility model are:

[0013] 1. This utility model utilizes a protective structure for rehabilitation training. A push block disengages a fixed block from its slot, and the forearm sleeve is pulled to adjust the distance between the two sleeves according to the patient's condition. The upper arm sleeve and forearm sleeve are then worn on the patient's arm. The control valve is opened, and air is injected into the air chamber by squeezing the balloon. The gas flows through the connecting tube to other air chambers, causing all air chambers to expand synchronously, thus fixing the protective structure to the patient's arm. A rotating knob drives a lead screw to rotate, which in turn causes the mounting block to slide within a groove. The slider, via a connecting plate, compresses or extends an adjusting spring, adjusting the force required for the connecting plate's rotation. This structural design allows the patient to flex and extend their arm during rehabilitation training, providing personalized support and flexible adjustment during arm rehabilitation. It solves the problem that traditional rehabilitation arm protective structures often cannot be flexibly adjusted according to the patient's specific condition, leading to limited rehabilitation effects. This significantly improves the targeting and effectiveness of rehabilitation training, greatly enhances patient participation and comfort, and accelerates the rehabilitation process and optimizes rehabilitation outcomes.

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

[0022] Please see Figure 1-5As shown, a rehabilitation arm protection structure includes an upper arm sleeve 1 and a forearm sleeve 2. Both the upper arm sleeve 1 and the forearm sleeve 2 have sleeves 3 fixedly installed inside. Multiple through holes are arrayed on the sleeves 3, and air chambers 4 are fixedly installed within each through hole. One end of each air chamber 4 penetrates the outer wall of the sleeve 3. Multiple air bags 5 are arrayed inside the sleeve 3 and fixedly installed on the air chambers 4. An elbow pad protrusion is provided at one end of the upper arm sleeve 1, and an elbow pad 10 is fixedly installed on the inner side of the elbow pad protrusion. One side of the upper arm sleeve 1 is fixedly... A connecting box 11 is fixedly installed on one side of the forearm sleeve 2. A slide rail 12 is fixedly installed on one side of the slide rail 12. A connecting plate 13 is slidably installed inside the slide rail 12. Multiple slots are arranged in an array on one side of the connecting plate 13. One end of the connecting plate 13 is rotatably installed inside the connecting box 11. An annular protrusion is formed in the middle of one end of the connecting plate 13. The annular protrusion is surrounded by an array of toothed grooves. An adjusting seat 14 is provided at one end of the connecting plate 13 and is fixedly installed inside the connecting box 11. A square opening is formed in one end of the adjusting seat 14. A control block 15 is slidably installed in a square hole. The control block 15 has teeth on one end near the connecting plate 13, which mesh with the toothed grooves on the connecting plate 13. A slide rod 16 is fixedly installed at the other end of the control block 15. A round hole is opened in the other end of the adjusting seat 14, and the other end of the slide rod 16 is slidably disposed in the round hole. A slider 18 is slidably installed on the slide rod 16, and an adjusting spring 17 is fitted onto the slide rod 16 between the slider 18 and the control block 15. A connecting rod 19 is rotatably mounted on the upper part of the slider 18. A sliding groove is opened on the upper part of the other end of the adjusting seat 14. An mounting block 21 is slidably mounted in the sliding groove. A threaded hole is opened in the mounting block 21. The other end of the connecting rod 19 is rotatably mounted on the mounting block 21. A mounting box 23 is provided on one side of the connecting plate 13 with a slot. A fixing block 24 is slidably mounted in the mounting box 23. A protrusion is opened on one side of the lower end of the fixing block 24, and the protrusion passes through the slide rail 12 and is slidably mounted in the slot.During operation, when using the protective structure to perform rehabilitation training on patients, push the push block 25. One end of the push block 25 slides along the wedge-shaped surface at the bottom of the fixed block 24, causing the fixed block 24 to rise within the mounting box 23. This causes the protrusion to disengage from the slot, compressing the return spring 27. Pull the forearm sleeve 2 to slide the slide rail 12 along the connecting plate 13. Adjust the distance between the upper arm sleeve 1 and the forearm sleeve 2 according to the patient's condition. Flip the push block 25, and the return spring 27 will lock the protrusion into the slot, fixing the connecting plate 13. Put the upper arm sleeve 1 and the forearm sleeve 2 on the patient's arm respectively, and then open the device. Control valve 9 injects air into air chamber 4 by squeezing balloon 8. The gas flows to other air chambers 4 through connecting pipe 6, causing all airbags 5 to inflate synchronously, fixing the protective structure to the patient's arm. Rotating knob 22 drives screw 20 to rotate, which in turn drives mounting block 21 to slide in a groove. Slider 18 compresses or extends adjusting spring 17 through connecting plate 13, adjusting the force required for rotating connecting plate 13. The patient flexes and extends their arm for rehabilitation training. The patient's elbow contacts elbow pad 10 to prevent injury.

[0023] An air tube 7 is fixedly connected to the outside of the air chamber 4. The same end of the air tube 7 passes through the upper arm sleeve 1 and the lower arm sleeve 2 respectively and is fixedly installed with a balloon 8. A control valve 9 is set near the connection between the upper end of the air tube 7 and the balloon 8. When the protective structure is used to perform rehabilitation training on the patient, the patient inflates the air chamber 4 by squeezing the balloon 8, so that the air bag 5 expands and provides support for the arm. When it is necessary to reduce the support force or adjust the state of the air bag 5, the gas in the air chamber 4 can be released by rotating the control valve 9, so that the air bag 5 contracts.

[0024] Each of the air chambers 4 is provided with a connecting pipe 6, and the two ends of the connecting pipe 6 are respectively fixedly connected to the sides of two adjacent air chambers 4. When the protective structure is used to perform rehabilitation training on the patient, when one of the air chambers 4 is inflated, the gas will flow through the connecting pipe 6 to the other air chambers 4, so that all the air bags 5 expand synchronously.

[0025] The adjusting seat 14 has a lead screw 20 inside its groove. One end of the lead screw 20 is rotatably installed inside the adjusting seat 14, and the other end is rotatably installed inside the connecting box 11. A knob 22 is fixedly installed through the connecting box 11. The mounting block 21 is slidably installed on the lead screw 20. During operation, when the patient is undergoing rehabilitation training using the protective structure, the patient drives the lead screw 20 to rotate by rotating the knob 22. The rotation of the lead screw 20 will cause the mounting block 21 to slide in the groove. The slider 18 compresses or extends the adjusting spring 17 through the connecting plate 13, adjusting the force required for the connecting plate 13 to rotate.

[0026] The lower end of the fixing block 24 is wedge-shaped on the other side. A push block 25 is vertically installed on one side of the lower end of the fixing block 24 and is slidably installed in the lower end of the mounting box 23. One end of the push block 25 is located at the bottom of the wedge-shaped surface of the fixing block 24, and the other end passes through the mounting box 23. When the patient is undergoing rehabilitation training using the protective structure, the patient pushes the push block 25. One end of the push block 25 slides along the bottom wedge-shaped surface of the fixing block 24, causing the fixing block 24 to rise in the mounting box 23 and the protrusion to disengage from the slot. Then, the distance between the forearm sleeve 2 and the upper arm sleeve 1 is adjusted by pulling the forearm sleeve 2.

[0027] The top of the mounting box 23 has a mounting hole, in which a limiting rod 26 is slidably installed. The lower end of the limiting rod 26 is fixedly connected to the top of the fixing block 24. A return spring 27 is provided in the upper end of the mounting box 23 and is fitted onto the limiting rod 26. During operation, when using the protective structure to perform rehabilitation training on the patient, when it is necessary to release the fixing block 24, simply release the push block 25. At this time, the return spring 27 will push the fixing block 24 to automatically reset, so that the protrusion is stuck in the slot, and the connecting plate 13 is fixedly installed in the slide rail 12.

[0028] Working principle: When performing rehabilitation training on a patient using the protective structure, pushing the push block 25 causes one end of the push block 25 to slide along the wedge-shaped surface at the bottom of the fixing block 24, raising the fixing block 24 within the mounting box 23. This causes the protrusion to disengage from the slot, compressing the return spring 27 and pulling the forearm sleeve 2, causing the slide rail 12 to slide along the connecting plate 13. The distance between the upper arm sleeve 1 and the forearm sleeve 2 is adjusted according to the patient's condition. Pushing the push block 25 is then flipped open, and the return spring 27 locks the protrusion into the slot, fixing the connecting plate 13. The upper arm sleeve 1 and forearm sleeve 2 are then worn on the patient's arm. Open the control valve 9 and inject air into the air chamber 4 by squeezing the balloon 8. The gas will flow to other air chambers 4 through the connecting pipe 6, causing all the airbags 5 to expand synchronously and fix the protective structure to the patient's arm. Rotate the knob 22 to drive the lead screw 20 to rotate. The rotation of the lead screw 20 will drive the mounting block 21 to slide in the groove. The slider 18 compresses or extends the adjusting spring 17 through the connecting plate 13, adjusting the force required for the connecting plate 13 to rotate. The patient flexes and extends his arm to perform rehabilitation training. The patient's elbow contacts the elbow pad 10 to prevent damage to the patient.
