Description

Technical Field

[0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a rehabilitation exercise device for cardiovascular patients. Background Art

[0002] Globally, cardiovascular disease (CVD) remains one of the leading causes of death and disability. It is estimated that there are about 330 million cardiovascular disease patients in China, and this number is still growing. For these patients, rehabilitation exercises are an indispensable part of the treatment process, especially aerobic exercise, such as walking and jogging, which has a significant effect on improving cardiovascular health and quality of life. However, traditional rehabilitation exercises have many limitations and safety risks.

[0003] In a hospital setting, patients with cardiovascular diseases usually need to undergo rehabilitation walking training in wards or corridors. This training method is not only limited by space, but also poses safety risks such as falls when exercising in corridors with high traffic. In addition, walking on flat ground cannot simulate uphill or downhill walking conditions, which limits the diversity and effectiveness of the exercise. Going up and down stairs as an alternative can provide some climbing training, but patients are at great risk of falling on the stairs, which may cause serious secondary injuries.

[0004] To address these issues, some cardiovascular patient rehabilitation exercise devices have appeared on the market, which are designed to provide a safer and more effective exercise environment. Although these devices meet the needs of patients to a certain extent, they often lack the ability to provide comprehensive rehabilitation training for patients, especially in the combination of leg and arm training.

[0040] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0041] The present embodiment provides a cardiovascular patient rehabilitation exercise device, which is mainly used to solve the problem that cardiovascular disease patients usually need to perform rehabilitation walking training in wards or corridors in a hospital environment. This training method is not only limited by space, but also there are safety risks such as falling when exercising in corridors with large traffic. In addition, walking on flat ground cannot simulate uphill or downhill walking conditions, which limits the diversity and effect of exercise. Going up and down stairs as an alternative can provide certain climbing training, but the risk of patients falling on the stairs is extremely high, which may cause serious secondary injuries. The following technical solutions are provided, which will be combined with Figure 1-Figure 10 Make a detailed description:

[0042] Embodiment 1:

[0043] A cardiovascular patient rehabilitation exercise device comprises a base 1, a leg exercise mechanism 2, an arm exercise mechanism 3 and an anti-fall mechanism 4, which is cleverly designed and easy to operate, and can effectively improve the patient's rehabilitation experience, wherein:

[0044] The base 1 is horizontally arranged on the ground to provide a stable platform, and a vertical device frame 11 is installed on the base 1 to provide support for the entire device;

[0045] The leg exercise mechanism 2 is used to exercise the patient's legs and can switch between passive walking, running and active walking. The leg exercise mechanism 2 simulates real walking and running movements, allowing the patient to exercise the legs in a passive or active mode. This design allows the patient to experience rehabilitation training similar to real walking without moving, effectively improving the diversity and effect of exercise;

[0046] The arm training mechanism 3 is installed on the top of the device frame 11 and is used to train the patient's arms. The patient can perform arm flexion and extension exercises to enhance the strength of the upper limbs. This method of coordinated training of the upper and lower limbs not only improves the rehabilitation efficiency, but also helps the patient recover his or her whole body functions.

[0047] The anti-fall mechanism 4 is installed on the device frame 11 and is used to protect the patient during exercise, effectively preventing the patient from falling during exercise and ensuring the safety of the patient.

[0048] Through this design, the device not only solves the space limitations and safety risk problems in traditional rehabilitation training, but also improves the effect of training by simulating real walking conditions. At the same time, the setting of the anti-fall mechanism 4 greatly reduces the safety hazards of patients during the rehabilitation process, allowing patients to perform rehabilitation exercises in a more comfortable and safe environment, which is of great significance for improving patients' rehabilitation enthusiasm and rehabilitation effects.

[0049] In the cardiovascular patient rehabilitation training device, the design of the leg training mechanism 2 is crucial, as it is directly related to the effect of the patient's leg rehabilitation training. Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 8 The leg exercise mechanism 2 includes a bearing plate 21 mounted on the top of the base 1, which serves as the basic platform of the leg exercise mechanism 2. A plurality of rotating rollers 22 distributed in an array are rotatably mounted on the bearing plate 21. These rotating rollers 22 not only provide a stable contact surface, but also can generate corresponding rotation when the patient's legs exert force, simulating the movement of the legs when walking. An integrated rotating belt 23 is sleeved on the plurality of rotating rollers 22. This design enables the rotating rollers 22 to rotate synchronously, providing the patient with a continuous and stable leg exercise experience.

[0050] A linkage wheel 24 is fixedly sleeved on the rotating shafts of the two outermost rotating rollers 22, and an integrated linkage belt 25 is sleeved between the two linkage wheels 24, ensuring the synchronous movement between the rotating rollers 22 and enhancing the coordination of the exercise. A friction wheel 26 is fixedly sleeved on the other end of the rotating shaft of one of the outermost rotating rollers 22, and the leg exercise mechanism 2 also includes a driving component 27 movably arranged on the base 1. The friction wheel 26 is driven to rotate by the driving component 27, so that the rotating belt 23 can rotate.

[0051] Specifically, the driving assembly 27 includes a slide rail 271 fixed to the top of the base 1 and arranged along the length direction of the linkage belt 1 25, a mounting seat 272 is slidably mounted on the slide rail 271, a reduction motor 273 is mounted on the mounting seat 272, and a friction wheel 274 corresponding to the friction wheel 1 26 is fixedly sleeved on the output end of the reduction motor 273. This design allows the mounting seat 272 to move within the full length of the slide rail 271, thereby adjusting the positions of the reduction motor 273 and the friction wheel 274. The rotation of the reduction motor 273 can be transmitted to the friction wheel 1 26 through the friction wheel 274, thereby driving the movement of the rotating belt 23, thereby realizing passive or active walking and running training of the patient's legs. By changing the output power of the reduction motor 273, the rotation speed of the rotating belt 23 can be changed, which is convenient for adjustment according to different needs of the patient.

[0052] The top of the base 1 is fixed with an electric push rod 275 arranged along the length direction of the slide rail 271. The output end of the electric push rod 275 is fixed to the mounting seat 272. The electric push rod 275 can push the mounting seat 272 to move along the slide rail 271, thereby adjusting the contact position and pressure between the friction wheel 274 and the friction wheel 1 26. This precise position adjustment is essential to adapt to the leg sizes and exercise requirements of different patients.

[0053] In summary, the design of the drive component 27 cleverly combines the electric push rod 275 and the reduction motor 273, and realizes precise driving of the patient's leg exercise by precisely controlling the position and pressure of the friction wheel 274. This design not only improves the flexibility and adaptability of the exercise, but also provides the patient with a safe and effective rehabilitation platform, which helps to accelerate the patient's rehabilitation progress. By contacting the friction wheel 2 274 with the friction wheel 1 26, the patient's passive training can be achieved, and by separating the friction wheel 2 274 from the friction wheel 1 26, the patient's active training can be achieved.

[0054] In the cardiovascular patient rehabilitation exercise device of the present invention, the design of the arm exercise mechanism 3 takes into account the rehabilitation needs of the patient's upper limbs. Two independent exercise mechanisms correspond to the patient's left and right arms, achieving coordinated exercise of both arms. For details, please refer to Figure 4 and Fig. 9The arm exercise mechanism 3 includes an installation box 31 vertically installed on the top of the device frame 11. The installation box 31 has an installation slot 32 inside. A connecting plate 33 is movably arranged inside the installation slot 32. A steel wire rope 34 with one end movably penetrating the bottom end of the installation box 31 is installed at the bottom of the connecting plate 33. A handle 35 is fixedly connected to the bottom end of the steel wire rope 34. A spring 36 sleeved on the outside of the steel wire rope 34 is connected between the bottom side of the connecting plate 33 and the inner wall of the installation slot 32. This design allows the connecting plate 33 to move up and down through the traction of the steel wire rope 34 to simulate the flexion and extension movement of the arm. The design of the handle 35 takes ergonomics into consideration to ensure that the patient can hold it comfortably during the exercise, while providing sufficient friction to prevent slipping. The setting of the spring 36 provides necessary elastic resistance for arm exercise, so that the patient can feel moderate resistance when performing arm flexion and extension exercises, thereby enhancing muscle strength and endurance.

[0055] Through this design, the arm exercise mechanism 3 can not only simulate real arm movements, but also adjust the resistance according to the specific situation of the patient to achieve personalized rehabilitation exercises. The elastic resistance of the spring 36 helps the patient to gradually increase muscle strength within a safe range, while the ergonomic design of the handle 35 ensures the comfort and safety of the exercise.

[0056] In the cardiovascular patient rehabilitation exercise device of the present invention, the design of the anti-fall mechanism 4 reflects a high degree of concern for patient safety. Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Fig.10 The number of anti-fall mechanisms 4 is two and they are symmetrically arranged. The anti-fall mechanism 4 includes a mounting plate 41 mounted horizontally on one side of the device frame 11. The top side of the other end of the mounting plate 41 is configured with a hinge groove 42. The anti-fall mechanism 4 also includes a semicircular ring plate 43. A hinge block 44 hinged in the hinge groove 42 is fixed on the semicircular ring plate 43. The semicircular ring plate 43 can be rotated to a horizontal state. When the semicircular ring plates 43 in the two anti-fall mechanisms 4 are rotated to a horizontal state, they form a complete circular ring on which a patient can be placed. This circular ring can place a patient in it to form a protective barrier.

[0057] In order to improve the comfort and protection effect of the patient, a sponge protective pad 45 is fixed to the inner side of the semicircular ring plate 43. This sponge protective pad 45 can not only reduce the discomfort of the patient when in contact with the semicircular ring plate 43, but also provide a buffer when the patient accidentally falls, reduce the impact force, and protect the patient from injury.

[0058] Through this design, the anti-fall mechanism 4 can not only provide stable support for the patient when performing rehabilitation exercises, but also can quickly transform into a protective barrier when the patient loses balance, thereby reducing the risk of falling. The addition of the sponge protective pad 45 further reflects the dual consideration of patient safety and comfort of the present invention.

[0059] Further, both ends of one of the semicircular ring plates 43 are configured with connecting grooves 431, both ends of the other semicircular ring plate 43 are movably inserted with connecting pins 432, and an accommodating groove 433 is configured on the outer side of the other semicircular ring plate 43, and a control plate 434 fixed to one end of the connecting pin 432 is movably provided inside the accommodating groove 433, and the other end of the connecting pin 432 is movably inserted into the corresponding connecting groove 431, and the connecting pin 432 is driven to move by the control plate 434, and one end of the connecting pin 432 is inserted into the inside of the connecting groove 431, so that the two semicircular ring plates 43 can be fixed, thereby ensuring the protection of the patient and preventing accidental movement or falling off due to excessive movement of the patient;

[0060] Through this design, the anti-fall mechanism 4 not only provides the safety protection required by the patient during exercise, but also allows medical staff to make quick adjustments based on the patient's specific situation to ensure the best protection effect. The coordinated use of the control panel 434 and the connecting pin 432 makes the adjustment of the anti-fall mechanism 4 more precise and reliable, thereby enhancing the practicality and safety of the entire device. This design reflects the dual focus of the present invention on safety and ease of operation while improving the patient's rehabilitation experience.

[0061] Embodiment 2:

[0062] In the second embodiment, the leg exercise mechanism 2 of the cardiovascular patient rehabilitation exercise device is further optimized to enhance the safety and stability of the patient during exercise. Specifically, this optimization involves the design improvement of the rotating belt 23, that is, anti-slip grooves are provided on its outer peripheral side;

[0063] The rotating belt 23 is one of the core components of the leg exercise mechanism 2. It directly contacts the patient's feet and simulates the movement of the legs when walking and running. On the basis of the first embodiment, we have added anti-skid patterns on the outer circumference of the rotating belt 23. The design of these anti-skid patterns takes into account the sliding problem that the patient may encounter during exercise, especially in the passive walking or running mode, the patient needs a stable contact surface to prevent slipping;

[0064] The provision of the anti-slip pattern not only increases the friction between the rotating belt 23 and the patient's feet, but also provides a better grip, allowing the patient to be more confident and comfortable when performing leg exercises. This design improvement helps reduce the risk of discomfort or falls caused by sliding during exercise, thereby improving the safety of exercise.

[0065] Embodiment three:

[0066] See also Figure 4 and Fig. 9 Embodiment 3 is a further optimization of embodiment 1. An adjustment plate 321 located on the top side of the connecting plate 33 is movably provided inside the mounting groove 32. A vertical threaded rod 322 with threads running through the top of the mounting box 31 is fixed in the middle of the top side of the adjustment plate 321. A turning handle 323 is fixed on the top of the threaded rod 322. This design allows the user to move the adjustment plate 321 up and down by rotating the turning handle 323, thereby adjusting the tension of the wire rope 34 and the height of the grip 35, so that the arm exercise can be fine-tuned according to different exercise intensities and comfort levels.

[0067] In addition, the installation box 31 is movably inserted on the top of the device frame 11, and a plurality of fixing holes 311 distributed in an array are constructed on one side of the installation box 31. A threaded rod 111 is threadedly inserted on the device frame 11, and one end of the threaded rod 111 is movably inserted in one of the fixing holes 311. A second turning handle 112 is fixed to the other end of the threaded rod 111. The user can adjust one end of the threaded rod 111 to insert into different fixing holes 311 by rotating the second turning handle 112, thereby changing the height of the installation box 31 to adapt to the height and exercise posture of different patients;

[0068] In summary, the optimized design in Example 3 significantly improves the adjustment flexibility and ease of use of the arm exercise mechanism 3 by introducing the adjustment plate 321 and improving the connection method between the mounting box 31 and the device frame 11. These improvements not only make arm exercises more personalized and comfortable, but also improve the overall adaptability and user experience of the device, reflecting the in-depth consideration and meticulous design of the present invention in improving the rehabilitation exercise effect of patients.

[0069] Embodiment 4:

[0070] In the fourth embodiment, we further optimize the anti-fall mechanism 4 of the cardiovascular patient rehabilitation exercise device to enhance its adjustability and adaptability. Figure 2 and Figure 5 , the two opposite sides of the device frame 11 are both constructed with vertical lifting grooves 113, and the two mounting plates 41 are respectively slidably mounted inside the two lifting grooves 113. This design allows the mounting plates 41 to slide inside the lifting grooves 113, so that the height of the mounting plates 41 can be adjusted to adapt to the height and exercise requirements of different patients. This sliding installation method provides more flexible adjustment, so that the anti-fall mechanism 4 can better adapt to the specific conditions of each patient;

[0071] In order to achieve this height adjustment, two vertically arranged screw rods 114 are rotatably installed between the base 1 and the top of the device frame 11, and the two mounting plates 41 are respectively threadedly sleeved on the two screw rods 114. The two screw rods 114 are fixedly sleeved with a linkage wheel 115, and the two linkage wheels 115 are sleeved with an integral linkage belt 116. A driving motor 117 fixed to the end of one of the screw rods 114 is fixed on the top of the device frame 11. One of the screw rods 114 is driven to rotate by the driving motor 117. Under the linkage of the linkage wheel 115 and the linkage belt 116, the two screw rods 114 rotate synchronously, thereby realizing the synchronous adjustment of the height of the two anti-fall mechanisms 4, which can adapt to patients of different heights.

[0072] The specific usage of this device is as follows:

[0073] When exercising with the cardiovascular patient rehabilitation exercise device, the patient first stands on the base 1, which is horizontally placed on the ground to provide a stable foundation for the entire exercise process. Then the patient stands on the rotating belt 23, which is a part of the leg exercise mechanism 2, which simulates real walking and running movements, allowing the patient to perform passive or active leg exercises. At this time, the two semicircular ring plates 43 are rotated to a horizontal state to surround the patient, and one end of the connecting pin 432 is driven by the control board 434 to be inserted into the interior of the connecting groove 431 to ensure the stability of the two semicircular ring plates 43;

[0074] For leg exercise, the patient can choose passive walking, running or active walking mode according to his / her ability. The driving assembly 27 includes a reduction motor 273 and an electric push rod 275. The reduction motor 273, the friction wheel 274 and the friction wheel 1 26 control the rotation of the rotating belt 23, thereby driving the patient's leg movement. By adjusting the output power of the reduction motor 273, the rotation speed of the rotating belt 23 can be changed to adapt to different rehabilitation stages and exercise needs of the patient.

[0075] For arm exercises, the patient's arms will hold the handles 35 of the arm exercise mechanism 3 and perform flexion and extension movements. This mechanism is installed on the top of the device frame 11, and through the cooperation of the connecting plate 33 and the wire rope 34, it simulates the natural movement of the arm. The patient can adjust the height and tension of the handle 35 by rotating the handle 1 323 or the handle 2 112, so that the arm exercise is more in line with personal comfort and rehabilitation goals.

[0076] It should be noted that the specific model specifications of the drive motor 117, the reduction motor 273 and the electric push rod 275 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail. The principles of these components are clear to those skilled in the art and do not need to be described in detail here.

[0077] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
