Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a cardiac training device for cardiac rehabilitation in cardiology. Background Technology

[0002] Cardiac rehabilitation refers to a comprehensive set of coordinated and purposeful interventions, including rehabilitation assessment, exercise training, diet and behavior, and medical adherence, to improve the function and structure of heart disease patients, optimize their physical and mental well-being, enhance their social participation, and prevent cardiovascular events.

[0003] Cardiac rehabilitation is divided into three phases. Phase I rehabilitation or in-hospital rehabilitation is initiated during the patient's hospitalization. Phase II cardiac rehabilitation is supervised outpatient rehabilitation that lasts for 3 to 6 months. Phase III cardiac rehabilitation includes exercise based at home or in a gym.

[0004] When exercising, older adults are not suitable for strenuous activities such as running. When older adults exercise, the exercise equipment needs to be adjusted according to their age.

[0005] For example, utility model patent application number 202120015381.6 discloses a cardiac rehabilitation training device for the elderly. Through the combination of mounting rod and rotating wheel, the rotating wheel can be driven to rotate when the user pushes the pedal to exercise, so that the patient can exercise. Through the combination of placement hole and counterweight, the number of counterweights can be adjusted according to the patient's needs, so that the device can adjust the training intensity according to the patient's needs.

[0006] However, when adjusting the training intensity, users need to get off the seat first, and then install or remove the counterweight to change the rotational resistance of the wheel. The adjustment process is cumbersome and cannot achieve real-time adjustment without stopping the machine. To address the existing problems, this paper studies and improves the existing technology to provide a cardiac rehabilitation cardiac trainer for cardiology. The aim is to solve the problems and improve its practical value through this technology. Utility Model Content

[0007] This invention provides a cardiac training device for cardiac rehabilitation in cardiology, in order to solve the problems and deficiencies mentioned in the background art.

[0008] To achieve the above objectives, the technical solution adopted by this cardiology rehabilitation cardiac training device is as follows:

[0009] The device includes a base plate, on which a first support block and a fixed block are arranged at intervals along the length direction. A handle is connected to the first support block, and a second support block is connected to the fixed block. A seat is installed inside the second support block. A wheel is rotatably connected to the fixed block, and a connecting rod is fixedly connected to the wheel. Pedals are hinged to both ends of the connecting rod. A guide groove extending along the length direction of the base plate is formed. The first support block is slidably disposed in the guide groove. A connecting block is connected to the side of the first support block near the wheel. The connecting block has an arc-shaped groove adapted to the outer diameter of the wheel, and a friction plate is installed in the arc-shaped groove.

[0010] Furthermore, an electromagnet is provided at the bottom of the first support block, and a magnetic material that cooperates with the electromagnet is provided in the guide groove. The electromagnet and the magnetic material cooperate to form an electromagnetic locking mechanism for the first support block, and an electromagnet switch is provided on the handle.

[0011] Furthermore, the first support block is provided with a sliding frame that can slide along the height direction. The side of the first support block is provided with a positioning through hole. The sliding frame is provided with multiple threaded positioning holes at equal intervals along the height direction. The sliding frame is fixed by aligning the positioning through hole with any positioning hole on the sliding frame and inserting an adjusting screw. The handle is fixedly connected to the top of the sliding frame.

[0012] Furthermore, the seat can slide along the height direction of the second support block. Multiple threaded positioning holes are equidistantly provided on the seat along the height direction. Positioning through holes are provided on the side of the second support block. Adjusting screws are inserted through the positioning through holes to align with any positioning hole on the seat, thereby fixing the seat.

[0013] Furthermore, the handle is U-shaped.

[0014] Furthermore, placement boxes are fixedly connected to both sides of the first support block.

[0015] The beneficial effects are:

[0016] This cardiac rehabilitation trainer for cardiology cleverly integrates a real-time adjustable wheel rotation resistance mechanism. Through the interaction between the connecting block on the first support block and the friction plate within its arc-shaped groove and the wheel, users can adjust the rotation resistance without stopping the machine, thus regulating the training difficulty based on their physical recovery and training needs. This ensures personalized and progressive rehabilitation training. Simultaneously, the electromagnetic locking mechanism utilizes the interaction between the electromagnet and the magnetic material in the guide groove. A switch on the handle locks and releases the first support block, enhancing both the trainer's stability and the user's safety.

[0017] In addition, the cardiac rehabilitation trainer for cardiology features a height-adjustable sliding frame and seat design, allowing users to freely adjust the height of the handles and seat according to their own height and training preferences, ensuring comfort and effectiveness during training. The U-shaped handle design further enhances grip comfort and convenience, reducing hand fatigue caused by prolonged training. The cardiac rehabilitation trainer also comes with a practical storage box, providing convenient storage space for users' belongings. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.

[0024] The technical solution adopted by the cardiac training device for cardiac rehabilitation in cardiology provided by this utility model is as follows:

[0025] Please see Figures 1-4 A cardiac rehabilitation cardiac trainer for cardiology includes a base plate 1 with a guide groove 10 extending along the length of the base plate 1. The guide groove 10 is T-shaped and is mainly used to guide the horizontal sliding of the first support block 2.

[0026] A locking mechanism is provided between the first support block 2 and the guide groove. Preferably, the locking mechanism consists of an electromagnet and a magnetic material. Specifically, an electromagnet is provided on one side of the bottom of the first support block 2, and a magnetic material is provided on the side wall of the guide groove 10 adjacent to the electromagnet along the length of the base plate 1. Normally, the electromagnet is energized, and the electromagnet attracts the magnetic material, thereby fixing the position of the first support block 2 within the guide groove 10. The power switch of the electromagnet is located on the handle 7. When the electromagnet is manually de-energized, it loses its magnetism, allowing the first support block 2 to slide normally within the guide groove 10.

[0027] The first support block 2 has a storage box 3 fixedly connected to both sides, which can hold the user's items. The sliding frame 5 is slidably connected to the first support block 2. The sliding frame 5 has multiple positioning holes 6 evenly spaced along its height, and all positioning holes 6 on the sliding frame 5 are threaded holes. The first support block 2 also has positioning through holes on its side. When the positioning through hole is aligned with any positioning hole 6 on the sliding frame 5, the adjusting screw 4 can be inserted to fix the sliding frame 5. Its threaded hole is threadedly connected to the adjusting screw 4. Preferably, the right end face of the adjusting screw 4 is rectangular, which facilitates the rotation of the adjusting screw 4.

[0028] A handle 7 is fixedly connected above the sliding frame 5. The handle 7 is U-shaped, and the user can choose to hold it horizontally or vertically according to the comfort of the grip. A connecting block 11 is fixedly connected to one side of the first support block 2. The side of the first connecting block 11 near the rotating wheel 15 has an arc-shaped groove that matches the outer diameter of the rotating wheel 15, and a friction plate 16 is provided in the arc-shaped groove.

[0029] A fixing block 14 is fixedly connected above the base plate 1. The first support block 2 and the fixing block 14 are arranged at intervals along the length of the base plate 1. A rotating wheel 15 is rotatably connected to the fixing block 14. A connecting rod 13 is fixedly connected to the rotating wheel 15. A pedal 12 is hinged to both ends of the connecting rod 13. A second support block 9 is fixedly connected above the fixing block 14. The seat 8 can slide along the height direction within the second support block 9. Multiple positioning holes 6 are also equidistantly opened below the seat 8 along the height direction. Positioning through holes are also provided on the side of the second support block 9. The principle of cooperation between the first support block 2 and the sliding frame 5 is the same. By passing the adjusting screw 4 through the positioning through hole on the second support block 9 and the positioning hole 6 below the seat, the height of the seat 8 can be limited.

[0030] When in use, place the cardiac rehabilitation heart trainer on the ground. When the height of the handle 7 needs to be adjusted according to the patient's height, turn the adjusting screw 4 out of the first support block 2, and then pull the sliding frame 5 to the appropriate height. The height of the handle 7 can be adjusted by turning the adjusting screw 4 into the positioning hole 6 of the sliding frame 5. The threaded connection can prevent the adjusting screw 4 from slipping out and causing it to be unable to support the height, thus reducing the safety hazards during use.

[0031] When the height of seat 8 needs to be adjusted, turn the adjusting screw 4 out of the second support block 9, then pull the seat 8 to the appropriate height. The height adjustment of seat 8 can be completed by turning the adjusting screw 4 into the positioning hole 6 of seat 8.

[0032] The patient can then sit on the seat 8, hold the handle 7, and place their feet on the pedal 12 to rotate the wheel 15 for exercise.

[0033] When it is necessary to adjust the rotational resistance of the rotating wheel 15 during exercise, there is no need to leave the seat 8. Simply turn off the electromagnet by using the electromagnet switch on the handle 7 to unlock the position of the first support block 2. Then, slightly pull the handle 7 to move the first support block 2 a short distance to the right. This will cause the connecting block 11 to move the friction plate 16 to the right as well, so that the friction plate 16 comes into contact with the rotating wheel 15, thereby increasing the frictional resistance of the rotating wheel 15. This allows the cardiac rehabilitation heart trainer for cardiology to adjust the training intensity at any time according to the patient's needs.

[0034] Users can adjust the force of the friction plate 16 against the rotating wheel 15 by pulling the handle 7, thereby changing the rotational resistance on the rotating wheel 15 at any time during exercise. After adjustment, the electromagnet is energized again to lock the position of the first support block 2, and stable rehabilitation training can continue. The adjustment process is very convenient, achieving a more precise and scientific rehabilitation training effect.

[0035] In the above embodiments, the locking mechanism consists of an electromagnet and a magnetic material. Of course, in other embodiments, the electromagnetic locking mechanism consisting of an electromagnet and a magnetic material can be replaced with a spring locking mechanism or a snap-locking mechanism.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
