Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to an arm exercise device for preventing Alzheimer's disease. Background Technology

[0002] Alzheimer's disease is a progressive neurodegenerative disease with an insidious onset. Clinically, it is characterized by comprehensive dementia manifestations such as memory impairment, aphasia, apraxia, agnosia, visuospatial skill impairment, executive dysfunction, and personality and behavioral changes. The cause remains unknown. Those who develop the disease before the age of 65 are called early-onset Alzheimer's disease, while those who develop it after the age of 65 are called late-onset Alzheimer's disease. In addition to drug prevention and treatment, late-onset Alzheimer's disease also requires some assistive devices for prevention and treatment. In daily life, it is important to help them with appropriate exercise and physical activity, provide them with external stimulation, help them establish conditioned reflexes in the brain, maintain physical function, slow down the decline of memory function, and improve their quality of life as much as possible. Patent document CN110063874A discloses an arm exercise device for preventing Alzheimer's disease, including a mounting base and an arm support frame. The arm support frame is connected to the mounting base via an L-shaped frame. A short rod section of the L-shaped frame forms a circumferential flipping positioning fit with the arm support frame. A flipping power motor is installed on the short rod section of the L-shaped frame. The output shaft of the flipping power motor passes through the short rod section and is connected to a drive wheel. A transmission wheel is installed at the end of the short rod section near the arm support frame. The drive wheel and the transmission wheel are connected by a belt. The transmission wheel is fixedly installed on... The arm support is fixedly connected to the drive shaft. The long rod section of the L-shaped frame is rotatably connected to the mounting base. The mounting base is provided with a U-shaped groove. The free end of the long rod section of the L-shaped frame is embedded in the U-shaped groove and connected by a rotating shaft. The rotating shaft is fixedly connected to the free end of the long rod section. The end of the rotating shaft extending out of the mounting base is driven by an up-and-down swinging motor. This device can swing and rotate the patient's entire arm up and down and perform elbow joint flexion training. It can play a good preventive exercise role for Alzheimer's patients. The device still has the following defects during use: (1) The forearm guard plate and the horizontal connecting plate of the device are fixedly connected. When in use, the wrist joint is fixed and cannot be exercised, which greatly reduces the exercise effect.

[0003] (2) The arm support of the device cannot be adjusted according to different patients, which makes the arm support poorly wrapping the arms of different patients during use, thus affecting the exercise effect.

[0004] (3) After exercise, the patient’s arm may experience poor blood circulation, resulting in soreness and numbness. However, the device does not have a corresponding massage structure to prevent poor blood circulation during or after exercise, which could cause soreness and numbness in the arm.

[0005] Therefore, there is an urgent need to design an arm exercise device to prevent Alzheimer's disease and solve the above problems. Summary of the Invention

[0006] To address the problems of existing devices, such as the inability to target the patient's wrist joints during exercise, the inability to adjust the arm support for different patients, and the lack of a massage structure, which leads to poor blood circulation and subsequent arm soreness and numbness during and after exercise, this invention provides an arm exercise device for preventing Alzheimer's disease, comprising a hand support mechanism, a forearm support mechanism, and an upper arm massage mechanism, wherein the hand support mechanism and the forearm support mechanism are rotatably connected, and the upper arm massage mechanism and the forearm support mechanism are rotatably connected. During exercise, the hand support mechanism can rotate 360 ​​degrees relative to the forearm support mechanism, allowing for targeted training of the wrist joint. The forearm support mechanism can adapt to different patients' arms, ensuring a comfortable grip and better training effect. Simultaneously, during forearm rotation training, the massage airbags on the forearm support mechanism massage the patient's arm, promoting blood circulation. Furthermore, the forearm support mechanism can drive the upper arm massage mechanism to massage the patient's upper arm, further promoting blood circulation throughout the arm, increasing the training effect, and preventing soreness and numbness during or after exercise.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An arm exercise device for preventing Alzheimer's disease includes a hand support mechanism, a forearm support mechanism, and an upper arm massage mechanism. The hand support mechanism is rotatably connected to the forearm support mechanism, and the upper arm massage mechanism is rotatably connected to the forearm support mechanism.

[0008] Preferably, the hand support mechanism includes a palm support plate and a finger support portion. The front ends of the palm support plate are connected to the finger support portion on both sides, forming a finger-penetrating gap between the palm support plate and the finger support portion. A spherical connector is provided at the rear end, and the spherical connector is rotatably connected to the forearm support mechanism.

[0009] Preferably, the forearm support mechanism includes a forearm support plate, an arc-shaped clamping plate, a telescopic adjustment assembly, and a knob. One end of the forearm support plate is provided with a spherical movable groove adapted to the hand support mechanism, and the other end is rotatably connected to the upper arm massage mechanism. The arc-shaped clamping plate is movably disposed on both sides of the forearm support plate through the telescopic adjustment assembly. The telescopic adjustment assembly is disposed inside the forearm support plate and passes through the forearm support plate to cooperate with the arc-shaped clamping plate. The knob is rotatably disposed at the bottom of the forearm support plate and is connected to the telescopic adjustment assembly.

[0010] Preferably, the telescopic adjustment assembly includes a gear, a rack, and a guide rod. The gear is connected to the knob, the rack meshes with the gear, and one end of the rack is connected to the arc-shaped clamping plate. The guide rod is disposed on the arc-shaped clamping plate and is movably inserted into the side of the forearm support plate.

[0011] Preferably, the upper arm massage mechanism includes a fixed plate, a linkage component, and a massage component. The fixed plate is rotatably connected to the forearm support mechanism. The linkage component is mounted on the fixed plate and connected to the forearm support mechanism and the massage component. The massage component is movably mounted on the fixed plate.

[0012] Preferably, the linkage component includes a main gear assembly, a driven gear assembly, and a drive block that mesh with each other. The main gear assembly is mounted on the support mechanism and is rotatably connected to the fixed plate. The driven gear assembly passes through the fixed plate and is connected to the drive block. The drive block is used in conjunction with the massage component.

[0013] Preferably, the massage assembly includes a sliding seat and two symmetrically arranged massage structures. The massage structures are rotatably mounted on the fixed plate, forming a V-shaped structure with a large upper opening and a small lower opening. The lower end of the massage structure is used in conjunction with the sliding seat, which is slidably mounted on the fixed plate and is used in conjunction with the drive block.

[0014] Preferably, the massage structure includes interconnected connecting rods and massage balls, the connecting rods are hinged to a fixed plate, and a roller is rotatably provided at the lower end of the connecting rods, the rollers being used in conjunction with a sliding seat.

[0015] Preferably, the sliding seat has a trapezoidal structure.

[0016] Preferably, the drive block has a strip-shaped structure with both ends being arc-shaped.

[0017] The beneficial effects of this invention are: This invention discloses an arm exercise device for preventing Alzheimer's disease. Compared with the prior art, the improvement of this invention lies in: (1) The present invention designs a hand support mechanism, which includes a palm support plate and a finger support part, and there is an arc-shaped finger gap between the two, which can realize two hand states during the patient's exercise process, namely, finger extension or bending. While the fingers can be further exercised, the patient can also freely choose the finger placement state during exercise according to the different severity of the disease, and use the fingers as the force point to exercise the arm. In addition, the hand support mechanism is 360 degrees rotatably connected to the forearm support mechanism, which can perform targeted exercises on the patient's wrist joint and improve the training effect.

[0018] (2) The present invention designs a forearm support mechanism, which includes a forearm support plate, an arc-shaped clamping plate and a telescopic adjustment component. The telescopic adjustment component can adjust the degree of clamping of the arc-shaped clamping plate on the patient's arm to meet the needs of different patients. At the same time, a massage airbag is provided on the inner side of the arc-shaped clamping plate.

[0022] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Example 1: See attached document Figure 1 The arm exercise device for preventing Alzheimer's disease shown includes a hand support mechanism 1, a forearm support mechanism 2, and an upper arm massage mechanism 3. The hand support mechanism 1 is used to place the patient's palm and fingers, the forearm support mechanism 2 is used to place the patient's forearm, and the upper arm massage mechanism 3 is used to place the patient's elbow, so that the upper arm massage mechanism 3 can massage the patient's upper arm. The hand support mechanism 1 and the forearm support mechanism 2 are rotatably connected and can rotate 360 ​​degrees. This arrangement allows the patient to exercise their wrist joints using the hand support mechanism 1 while using the forearm support mechanism 2. The upper arm massage mechanism 3 is rotatably connected to the forearm support mechanism 2 and can be fixedly mounted on various devices (such as hospital beds or wheelchairs). This allows the exercise device of the present invention to be applied in various scenarios (indoors and outdoors). Patients can also exercise their arms in various postures. When the patient uses the forearm support mechanism 2 to exercise, the forearm support mechanism 2 simultaneously drives the upper arm massage mechanism 3 to massage both sides of the patient's upper arm, promoting blood circulation and preventing arm soreness and numbness. See attached document Figure 2-3As shown, the hand support mechanism 1 includes a palm support plate 101 and a finger support portion 102. The front ends of the palm support plate 101 are connected to the finger support portion 102, forming a finger-penetrating gap between the palm support plate 101 and the finger support portion 102. This finger-penetrating gap allows the patient to bend along both axes and grasp the palm support plate 101. This configuration of the hand support mechanism 1 allows the patient to maintain two hand positions during exercise, namely, finger extension or bending, to exercise the fingers. Patients with different degrees of illness can freely choose the finger placement position during exercise to satisfy the process of arm exercise with the fingers as the force point. In order to facilitate the fixation of the patient's fingers, the present invention provides a groove 102-1 on the finger support portion 102 for use with the fingers. The rear end of the palm support plate 101 is provided with a spherical connector 103, which is rotatably connected to the forearm support mechanism 2. Specifically, the spherical connector 103 is movably connected to the spherical movable groove 201-1, and the spherical connector 103 can rotate 360 ​​degrees within the spherical movable groove 201-1, thereby realizing multi-angle rotation of the palm support plate 101 relative to the finger support part 102. The usage process and principle of the arm exercise device for preventing Alzheimer's disease in this embodiment are as follows: First, fix the device to a bed, wheelchair, or other medical device via the upper arm massage mechanism 3. Then, place the forearm on the forearm support mechanism 2 and fix it in place. Place the palm on the palm support plate 101 and the fingers on the finger support part 102, or bend the fingers and insert them into the gap between the palm support plate 101 and the finger support part 102 to perform finger training. At the same time, patients with different degrees of disease can freely choose the finger placement state during exercise to meet the process of arm exercise with the fingers as the force point.

[0024] Example 2: See attached document Figure 3-4 As shown, based on Example 1, Example 2 differs from Example 1 in that, considering that different patients have different arm sizes and that poor blood circulation in the arm during long-term exercise can easily lead to soreness and numbness, a forearm support mechanism 2 is provided. This mechanism can adapt to the arms of different patients and can massage the arm during training to promote blood circulation and improve training effectiveness. For details, please refer to the attached document. Figure 3-4 As shown, the forearm support mechanism 2 includes a forearm support plate 201, an arc-shaped clamping plate 202, a telescopic adjustment component 203, and a knob 204. One end of the forearm support plate 201 is provided with a spherical movable groove 201-1 adapted to the hand support mechanism 1, and the other end is rotatably connected to the upper arm massage mechanism 3. The arc-shaped clamping plate 202 is movably arranged on both sides of the forearm support plate 201. By manually turning the knob 204, the telescopic adjustment component 203 is moved. The telescopic adjustment component 203 causes the two arc-shaped clamping plates 202 to move relative to the forearm support plate 201, thereby clamping the forearm placed on the forearm support plate 201. This ensures that the clamping tightness of the forearm meets the training requirements. Considering the problem of obstructed blood circulation during long-term exercise, a massage airbag 202-1 is provided on the inner side of the arc-shaped clamping plate 202. When the patient's forearm rotates back and forth in the arc-shaped clamping plate 202, the massage airbag 202-1 also massages the patient's forearm accordingly, promoting blood circulation. Furthermore, the telescopic adjustment component 203 is disposed inside the forearm support plate 201 and passes through the forearm support plate 201 and is connected to the arc-shaped clamping plate 202. The knob 204 is rotatably disposed at the bottom of the forearm support plate 201 and is connected to the telescopic adjustment component 203. The telescopic adjustment component 203 includes a gear 203-1, a rack 203-2 and a guide rod 203-3. The gear 203-1 is connected to the knob 204. The rack 203-2 is symmetrically meshed with the gear 203-1 and one end is connected to the arc-shaped clamping plate 202. The guide rod 203-3 is disposed on the arc-shaped clamping plate 202 and is movably inserted into the side of the forearm support plate 201. Manually turn knob 204. Turning knob 204 drives gear 203-1 to rotate. Gear 203-1 rotates and pushes rack 203-2 to move. The movement of rack 203-2 drives the arc-shaped clamping plate 202 on it to move, so that the arc-shaped clamping plate 202 moves towards the forearm support plate 201, thereby clamping the forearm resting on the forearm support plate 201. The usage process and principle of the arm exercise device for preventing Alzheimer's disease in this embodiment are as follows: After placing the forearm on the forearm support plate 201, manually turn the knob 204. The rotation of the knob 204 drives the gear 203-1 to rotate. The rotation of the gear 203-1 pushes the rack 203-2 to move. The movement of the rack 203-2 drives the arc-shaped clamping plate 202 on it to move, so that the arc-shaped clamping plate 202 moves towards the forearm support plate 201, thereby clamping the forearm placed on the forearm support plate 201, so that the clamping tightness of the forearm meets the exercise requirements. At the same time, when the patient's forearm rotates back and forth in the arc-shaped clamping plate 202, the massage airbag 202-1 on it also massages the patient's forearm accordingly, promoting blood circulation. Example 3: See attached document Figure 6-9As shown, based on Example 2, Example 3 differs from Example 2 in that, considering that prolonged exercise without proper blood circulation can easily lead to arm soreness and numbness, and to increase the patient's arm exercise effect, the present invention also includes an upper arm massage mechanism 3. The upper arm massage mechanism 3 is rotatably connected to the lower arm support mechanism 2. The lower arm support mechanism 2 drives the upper arm massage mechanism 3 to move, so that the upper arm massage mechanism 3 can massage the patient's upper arm, promote blood circulation, and at the same time, the upper arm massage mechanism 3 can be fixed on various medical machines (such as: hospital beds, wheelchairs) to meet the needs of exercise in multiple scenarios; For details, please refer to the attached document. Figure 6 As shown, the upper arm massage mechanism 3 includes a fixed plate 301, a linkage component 302, and a massage component 303. The fixed plate 301 is rotatably connected to the forearm support mechanism 2. The linkage component 302 is connected to the forearm support mechanism 2 and is also rotatably connected to the fixed plate 301. The bottom end of the massage component 303 is slidably connected to the fixed plate 301, and the top end is hinged to the fixed plate 301. The fixed plate 301 can be fixed on a hospital bed or wheelchair to meet the needs of exercise in multiple scenarios. When the patient exercises, the forearm support plate 201 rotates back and forth, which in turn causes the linkage component 302 on it to rotate. The linkage component 302 causes the massage component 303 to move up and down along the fixed plate 301, thereby opening and closing the massage component 303 to massage the patient's upper arm. Further references Figure 7-8 As shown, the linkage component 302 includes a main gear assembly 302-1, a driven gear assembly 302-2, and a drive block 302-3 that mesh with each other. The main gear assembly 302-1 is mounted on the support mechanism 2 and is rotatably connected to the fixed plate 301. The driven gear assembly 302-2 passes through the fixed plate 301 and is connected to the drive block 302-3. The drive block 302-3 is used in conjunction with the massage component 303. Further references Figure 8-9 As shown, the massage assembly 303 includes a sliding seat 303-1 and two symmetrically arranged massage structures 303-2. The massage structures 303-2 are rotatably mounted on the fixed plate 301, forming a V-shaped structure with a large upper opening and a small lower opening. The lower end of the massage structure 303-2 is used in conjunction with the sliding seat 303-1. The sliding seat 303-1 is slidably mounted on the fixed plate 301, and a drive groove 303-1A adapted to the drive block 302-3 is provided at its lower end. The massage structure 303-2 is hinged to the fixed plate 301 and slidably connected to the sliding seat 303-1. The massage structure 303-2 includes a connecting rod 303-2A and a massage ball 303-2B that are connected to each other. The connecting rod 303-2A is hinged to the fixed plate 301, and a roller 303-2C is rotatably provided at the lower end of the connecting rod 303-2A. The roller 303-2C is used in conjunction with the sliding seat 303-1. The forearm support plate 201 rotates back and forth, driving the main gear assembly 302-1 to rotate. The main gear assembly 302-1 drives the driven gear assembly 302-2 to rotate, and the driven gear assembly 302-2 drives the drive block 302-3 to rotate. The drive block 302-3 rotates and is locked in the drive groove 303-1A, which in turn drives the sliding seat 303-1 to slide up and down on the fixed plate 301. The sliding seat 303-1 drives the roller 303-2C to slide on top, which in turn causes the connecting rod 303-2A to rotate around the hinge point, thereby changing the included angle between the two connecting rods 303-2A, so that the massage ball 303-2B on the connecting rod 303-2A can massage the patient's upper arm. The usage process and principle of the arm exercise device for preventing Alzheimer's disease in this embodiment are as follows: When the patient exercises, the forearm support plate 201 rotates back and forth, the forearm support plate 201 drives the main gear assembly 302-1 to rotate, the main gear assembly 302-1 drives the driven gear assembly 302-2 to rotate, the driven gear assembly 302-2 drives the drive block 302-3 to rotate, the drive block 302-3 drives the sliding seat 303-1 to slide up and down on the fixed plate 301, the sliding seat 303-1 drives the roller 303-2C to slide on, thereby causing the connecting rod 303-2A to rotate around the hinge point, thereby changing the included angle between the two connecting rods 303-2A, so that the massage ball 303-2B on the connecting rod 303-2A massages the patient's upper arm.

[0025] The process and principle of using the arm exercise device for preventing Alzheimer's disease of the present invention are as follows: First, fix the fixing plate 301 on the wheelchair or hospital bed, then place the forearm in the forearm support mechanism 2, then place the palm on the palm support plate 101, and place the fingers in the groove 102-1 on the finger support part 102, or bend the fingers and insert them into the gap between the palm support plate 101 and the finger support part 102 to form a finger-penetrating gap; Then, manually turn knob 204. The rotation of knob 204 drives gear 203-1 to rotate. The rotation of gear 203-1 pushes rack 203-2 to move. The movement of rack 203-2 drives the arc-shaped clamping plate 202 on it to move, so that the arc-shaped clamping plate 202 moves towards the forearm support plate 201, thereby clamping the forearm resting on the forearm support plate 201, so that the clamping tightness of the forearm meets the training requirements. The clamping tightness of the arc-shaped clamping plate 202 on the patient's arm can realize two training modes. When the arc-shaped clamping plate 202 clamps the patient's arm more loosely, when the patient's arm moves left and right, the massage airbag 202-1 on it massages the muscle groups on the patient's arm. When the patient's arm is tightly clamped, the patient exerts force with their hand in a bent or straight position, causing the forearm to rotate back and forth within the arc-shaped clamping plate 202. During exercise, the patient causes the forearm support plate 201 to rotate back and forth, which in turn causes the main gear assembly 302-1 to rotate. The main gear assembly 302-1 then causes the driven gear assembly 302-2 to rotate, which in turn causes the drive block 302-3 to rotate. The drive block 302-3 rotates and locks into the drive groove 303-1A, which in turn causes the sliding seat 303-1 to slide up and down on the fixed plate 301. The sliding seat 303-1 slides, causing the roller 303-2C to slide upwards, which in turn causes the connecting rod 303-2A to rotate around the hinge point, thereby changing the angle between the two connecting rods 303-2A and allowing the massage ball 303-2B on the connecting rod 303-2A to massage the patient's upper arm.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
