[0020] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. Usually, the components of the embodiments of the present application described and illustrated herein can be arranged and designed in various different configurations.

[0021] The inventors have found through research that existing cardiovascular function enhancement devices can only perform one type of exercise, and the counterweight during training cannot be adjusted according to personal needs.

[0022] Based on the above findings, the present application proposes a cardiovascular function enhancement device for preventing cardiovascular diseases. Through the cooperation of a foot pedal mechanism, a load mechanism, and a pulley mechanism, it realizes simulating lower limb movement and providing resistance load, thereby enhancing cardiovascular function. Among them, the components of the load mechanism cooperate with each other to adjust the movement resistance through the magnitude of the current. At the same time, the gas is communicated with the foot pedal mechanism through the air outlet pipe to achieve dynamic resistance cooperation; the components of the foot pedal mechanism work together to ensure stable movement and provide various movement modes such as active and passive; the pulley mechanism realizes the force transmission and movement synchronization between the foot pedal mechanism and the load mechanism through the cooperation of multiple pulleys and ropes. The present application can provide a variety of movement mode simulations and can flexibly adjust the resistance load according to personal needs to achieve precise and personalized cardiovascular function training. Embodiment

[0023] Refer to Figures 1 - 18 , the present application discloses a cardiovascular function enhancement device for preventing cardiovascular diseases, including a base 1 as the foundation of the entire device. The base 1 is composed of two horizontally and vertically arranged long rods. One end of the base 1 is fixedly provided with a bottom plate 101, and the other end is fixedly provided with a seat cushion 102 through a support component. A support seat 103 is fixedly provided on the bottom plate 101. Two vertically upward extending support columns 104 are symmetrically distributed on the support seat 103. The top of the support column 104 is connected to a horizontally extending cross beam 105 to form a stable frame structure, providing an installation foundation for other components.

[0024] Next, a load mechanism 2 is provided above the support seat 103. The load mechanism 2 penetrates the support column 104 and is used to provide resistance load, including a housing 201, a counterweight 202, and a magnetic resistance component 3.

[0025] Specifically, the housing 201 is a protective component, in the shape of a shell. Its main body part has regularly arranged hollow long holes, is arranged on the bottom plate 101, and is located outside the support seat 103, playing a role in protecting and blocking the internal structure. The counterweight 202 has a hole for the support column 104 to penetrate, is slidably connected to the support column 104, and can slide up and down along the support column 104 to provide a basic resistance through its own gravity.

[0026] The magnetic resistance component 3 includes a conductor 301, a coil 302, an airbag 303, a magnet 304, and an air outlet pipe 305.

[0027] Specifically, the conductor 301 is connected above the support base 103, preferably one of iron, cobalt, nickel, etc. A coil 302 is closely sleeved outside the conductor 301. When the coil 302 is energized, according to Ampere's law, the magnetic field generated by the energized coil will magnetize the conductor 301, making it magnetic, and the magnetic direction is the same as that generated by the energized coil. It should be noted that the magnitude of the input current can determine the strength of the generated magnetic field, and the direction of the input current can determine the direction of the magnetic field. Moreover, the magnitude and direction of the input current can be set in advance according to requirements. For example, when the counterweight 202 moves upward, the direction of the current is clockwise. At this time, the N pole of the generated magnetic field is upward and the S pole is downward. When the counterweight 202 moves downward, the direction of the current is counterclockwise. At this time, the N pole of the generated magnetic field is downward and the S pole is upward.

[0028] It should be noted that the control of the magnitude and direction of the input current adopts the existing control method. For example, referring to an electro-permanent magnetic fixture for manipulator handling disclosed in the patent number 201320788169.9, a position sensor, such as a Hall sensor US5881, is installed on the counterweight 202 to detect the displacement direction of the counterweight 202. The magnitude and direction of the input current are controlled by a programmable H-bridge drive circuit (refer to the application manual of Texas Instruments LM298N chip). This circuit can automatically switch the current direction according to the position sensor signal.

[0029] The airbag 303 is connected above the conductor 301 by hot pressing and bonding. Air outlets 3031 are provided on both sides thereof. The magnet 304 is connected above the airbag 303 by hot pressing and bonding. The upper end of the magnet 304 is fixedly connected to the counterweight 202, enabling the airbag 303 to be normally compressed and extended under the drive of the counterweight 202. Preferably, the N pole of the magnet 304 faces upward and the S pole faces downward.

[0030] One end of the air outlet pipe 305 is connected to the air outlets 3031 on both sides of the airbag 303 by means of socket connection and sealant fixation, and the other end is used to communicate with the foot pedal mechanism 4, so that the gas in the airbag 303 enters the foot pedal mechanism 4 through the air outlet pipe 305 and synchronously cooperates with the foot pedal mechanism 4 for movement.

[0031] It should be noted that a limit plate 203 is provided on the support base 103 at a height position relative to the magnetoresistive assembly 3 to limit the lowest descending position of the counterweight 202. That is to say, the lowest descending position of the counterweight 202 is flush with the top of the initial state of the magnetoresistive assembly 3.

[0032] When the patient pulls up the counterweight 202, the current direction passed through the guide coil 302 is clockwise, and the generated magnetic field direction is that the N pole is upward and the S pole is downward. At this time, the N pole of the magnet faces upward and the S pole faces downward. Then when the counterweight 202 moves upward, the magnetic field generated after the conductor 301 is magnetized attracts the magnetic field of the magnet 304, increasing the resistance to the upward movement of the counterweight 202. In this process, when the patient pulls the counterweight 202, a greater resistance load needs to be overcome, which can effectively increase the training intensity. As the counterweight 202 rises, the airbag 303 connected below the magnet 304 is stretched, its volume gradually becomes larger, and the internal pressure decreases.

[0033] When the counterweight 202 falls back, the current direction passed through the guide coil 302 is clockwise, and the generated magnetic field direction is that the N pole is downward and the S pole is upward. At this time, the N pole of the magnet faces upward and the S pole faces downward. Then when the counterweight 202 moves downward, the magnetic field generated after the conductor 301 is magnetized repels the magnetic field of the magnet 304, increasing the resistance to the downward movement of the counterweight 202 and preventing it from falling rapidly. As the counterweight 202 descends, the airbag 303 connected below the magnet 304 is compressed, its volume gradually becomes smaller, and the internal pressure increases. Since the air outlet pipe 305 is connected to the foot pedal mechanism 4, the gas in the airbag 303 flows through the air outlet pipe 305 to the foot pedal mechanism 4, affecting the movement of the foot pedal mechanism 4.

[0034] Next, a foot pedal mechanism 4 is provided in the middle of the base 1 for the patient to step on and exert force to simulate lower limb movement, including a support rod 401, a support beam 402, a foot pedal assembly 5, a leg fixing assembly 6, and a pushing assembly 7.

[0035] Specifically, the support rod 401 is vertically arranged on the support seat 103 and serves as the main support component of the entire foot pedal mechanism 4, providing an installation basis for other components. A support beam 402 is fixedly arranged on the support rod 401, and the support beam 402 extends horizontally under the seat cushion 102, playing a role of connection and load bearing.

[0036] Furthermore, foot pedal assemblies 5 are arranged on both sides of the support beam 402 through connecting rods 403, which is the part where the patient directly steps on and exerts force, including a fixed box 501, a movable plate 502, and a foot pedal 503.

[0037] Among them, the fixed box 501 is a semi-closed box-shaped structure, which is fixedly arranged on both sides of the support beam 402 through the connecting rod 403. A plurality of elastic members 5011 are arranged inside the upper part thereof. Preferably, the elastic members 5011 are springs. A pushing groove 5013 is formed on one side of the fixed box 501 close to the load mechanism 2. A movable plate 502 is hinged below the fixed box 501. The movable plate 502 can be rotatably connected relative to the fixed box 501, and a sliding groove 5021 is formed on the movable plate 502 for providing activity guidance for the foot pedal 503.

[0038] The foot pedal 503 penetrates and is slidably arranged on the sliding groove 5021 of the movable plate 502. The foot pedal 503 includes a stepping pedal 5031 and a groove plate 5032 connected to one side of the stepping pedal 5031. Anti-slip textures are provided on the stepping pedal 5031, and anti-slip grooves are formed on the groove plate 5032.

[0039] Furthermore, the foot pedal 503 is hinged with a leg fixing assembly 6 extending towards the direction close to the seat cushion 102, including two first leg fixing members 601 and a second leg fixing member 602, which are respectively used for fixing the calf and thigh of the patient. The first leg fixing member 601 and the second leg fixing member 602 are movably connected by a hinged manner. The patient can adjust the position and angle of the leg fixing assembly 6 according to their own leg length and posture. Both the first leg fixing member 601 and the second leg fixing member 602 include a leg fixing frame 603, a leg airbag 604 and a leg restraint 605, which are used for fixing the patient's leg, providing comfortable support and safety guarantee.

[0040] Specifically, the leg fixing frame 603 is the main support, and its shape is designed according to the physiological curve of the human leg, which can fit the contour of the leg, construct a stable and comfortable accommodation space, and provide reliable support for the leg. The leg airbag 604 is arranged inside the leg fixing frame 603 by means of hot pressing and bonding, and the leg airbags 604 of the first leg fixing member 601 and the second leg fixing member 602 are interconnected, and can adjust the wrapping force on the leg by inflating and deflating, pressing the leg vein blood vessels, and promoting the blood return speed. Leg restraints 605 are connected to both sides of the leg fixing frame 603 by convenient connection methods such as Velcro or buckles, which are convenient for the patient to quickly adjust the tightness, ensure that the leg is firmly fixed inside the leg fixing frame 603, and prevent the leg from displacing during the movement process.

[0041] Furthermore, a pushing assembly 7 is arranged on one side of the foot pedal 503 close to the support rod 401, which is used for pushing the foot pedal assembly 5 to move, including an eccentric structure, a liquid cavity 703, a connecting pipe 705, a telescopic member 706 and a moving push rod 708.

[0042] Specifically, the eccentric structure includes a motor 701 and an eccentric wheel 7021. The motor 701 is fixedly installed on the support rod 401. An eccentric wheel 702 is connected to the output shaft of the motor 701. An eccentric rod 7021 is provided on the eccentric wheel 702. When the motor 701 drives the eccentric wheel 702 to rotate, the eccentric rod 7021 on the eccentric wheel will perform an eccentric circular motion.

[0043] The liquid chamber 703 is fixedly arranged on the base 1, and a swing member 704 is movably connected through it. The swing member 704 includes a swing rod 7041 and a swing plate 7042. The swing plate 7042 is hinged on the liquid chamber 703 and divides the liquid chamber 703 into two left and right cavities. One end of the swing rod 7041 is slidably connected to the eccentric rod 7021, and the other end is fixedly connected to the swing plate 7042. When the eccentric rod 7021 performs a circular motion, it will drive the swing rod 7041 to move left and right, and the swing rod 7041 will drive the swing plate 7042 to swing left and right in the liquid chamber 703.

[0044] Liquid outlets 7031 are respectively arranged on the left and right cavities. One end of a connecting pipe 705 is connected to the liquid outlet 7031, and the other end is connected to a moving push rod 708. A piston rod 7081 is arranged above the moving push rod 708, which is used to guide the liquid in the liquid chamber 703 to the moving push rod 708 and then push the piston rod 7081 to achieve the transmission of liquid and the transfer of pressure.

[0045] The telescopic member 706 includes a first telescopic rod 7061, a second telescopic rod 7062, and a third telescopic rod 7063 that are sequentially hinged. The first telescopic rod 7061 is hinged to the inner bottom of the fixed box 501. A push plate 707 is hinged above the third telescopic rod 7063. The second telescopic rod 7062 is fixedly connected to the piston rod 7081 through a push rod 7082 that penetrates through the push groove 5013.

[0046] After the motor 701 is started, the output shaft of the motor 701 drives the eccentric wheel 702 to rotate, and the eccentric rod 7021 on the eccentric wheel 702 will push the swing member 704 that is slidably connected to it to swing left and right in the liquid chamber 703.

[0047] When the swing member 704 swings to the left, the left cavity space of the liquid chamber 703 is compressed, and the liquid in the chamber is squeezed, increasing the pressure. Under the action of the pressure, the liquid flows into the moving push rod 708 through the liquid outlet 7031 of the left cavity via the connecting pipe 705, which will push the piston rod 7081 to move, and then drive the telescopic member 706 to extend through the push rod 7082, thereby driving the push plate 707 to move upward, and thus pushing the left foot pedal upward. Similarly and opposite to the left chamber, the liquid pressure inside the right chamber of the liquid chamber 703 decreases, thereby pushing the left foot pedal downward. Because the swing member 704 swings periodically, changing the liquid pressure in the left and right chambers, realizing the up-and-down movement of both legs, which helps to simulate the movement of the lower limbs of the human body and the relaxation of the legs after active training, consolidating the training effect.

[0048] Further, a hanging ring 5012 is provided on the upper side inside the fixed box 501, and a hook 5033 is provided above the groove plate 5032. The hanging ring 5012 and the hook 5033 can cooperate with each other to fix the foot pedal 503 and prevent the foot pedal 503 from sliding on the movable plate 502.

[0049] Next, a pulley mechanism 8 is further provided between the foot pedal mechanism 4 and the load mechanism 2, and the two cooperate with each other through the pulley mechanism 8. The pulley mechanism 8 includes a first pulley assembly 801 and a second pulley assembly 802 connected to each other.

[0050] Specifically, the first pulley assembly 801 includes: a first pulley 8011, a first pulling rope 8012, and a first pull rod 8013.

[0051] The first pulley 8011 is arranged above the support beam 402 to change the direction of the force. The first pulling rope 8012 is wound around the first pulley 8011, and one end is connected to the first pull rod 8013. When the patient sits on the seat cushion 102 and steps on the foot pedal 503, and pulls the first pull rod 8013 by hand, active training can be realized.

[0052] Further, the second pulley assembly 802 includes a second pulley 8021, a third pulley 8022, a fourth pulley 8023, a fifth pulley 8024, and a second pulling rope 8025.

[0053] Specifically, the second pulley 8021 is fixed at one end of the cross beam 105, serving as a support point for the second pulling rope 8025 to change the pulling direction of the second pulling rope 8025. The third pulley 8022 is fixed at the other end of the cross beam 105 and acts together with the second pulley 8021 to further guide the direction of the second pulling rope 8025, enabling the pulling force to be effectively transmitted to the counterweight 202. The fourth pulley 8023 is fixed at one end of the cross beam 105 close to the third pulley 8022 to further guide the direction of the second pulling rope 8025.

[0054] The fifth pulley 8024 is connected to the end of the first pulling rope 8012 far from the first pull rod 8013, used to change the direction of the second pulling rope 8025 and connect the first pulley assembly 801 and the second pulley assembly 802. The second pulling rope 8025 is successively arranged around the second pulley 8021, the fourth pulley 8023, the fifth pulley 8024, and the third pulley 8022, with one end connected to the second pull rod 8026 and the other end connected to the counterweight 202.

[0055] When the patient stands and pulls the second pull rod 8026, the second pulling rope 8025 connected thereto drives the counterweight 202 to move up and down through the second pulley 8021, the fourth pulley 8023, the fifth pulley 8024, and the third pulley 8022 respectively. During this process, only the second pulling rope 8025 participates in the movement, and the first pulley assembly 801 remains stationary. This operation method facilitates the patient to directly control the position of the counterweight 202 through manual adjustment in the standing state, thereby flexibly adjusting the load resistance to meet diverse training intensity requirements.

[0056] When the patient sits on the seat cushion 102 and pulls the first pull rod 8013, the first pulling rope 8012 connected thereto drives the fifth pulley 8024 through the first pulley 8011 respectively. At this time, due to the limiting effect of the second pull rod 8026 and the cross beam 105, the part of the second pulling rope 8025 close to the second pulley 8021 remains stationary. Therefore, when pulling the first pull rod 8013, the force will be transmitted through the fifth pulley 8024, and only the part of the second pulling rope 8025 from the fourth pulley 8023 to the counterweight 202 will move. When the patient performs a foot pedal movement in the sitting position, through the linkage of the foot pedal mechanism 4 and the pulley mechanism 8, the stepping force can be converted into the power to pull the counterweight 202, realizing the synchronous cooperation of the foot pedal movement and the resistance adjustment.

[0057] It should be noted that a control member 404 is provided on the support beam 402, and the user can adjust parameters such as the start and stop of the motor 701, the rotation speed, the current flow rate into the induction coil 302, and the speed required to be controlled in this device according to the control member 404.

[0058] Application Example 1: Standing Pulling Training Mode When the patient stands and pulls the second pull rod 8026, the pulling force pulls the counterweight 202 up and down through the second pull rope 8025. When the counterweight 202 is pulled up, a clockwise current is passed through the guide coil 302. After the conductor 301 is magnetized, the N pole faces upward, and the N pole of the magnet 304 repels the same sex, increasing the resistance to upward movement. The self-gravity of the counterweight 202 is superimposed with the magnetic resistance to form a composite resistance load (the magnitude of this resistance can be adjusted by the patient himself according to the actual situation). This action mainly exercises the muscles of the back and chest. At the same time, during the movement, the oxygen demand of the body increases, promoting aerobic respiration, thereby enhancing the cardiopulmonary function.

[0059] Application Example 2: Active sitting posture training mode The patient sits on the seat cushion 102, the legs are fixed on the leg fixing assembly 6, the feet step on the foot pedal 503, and the hand pulls the first pull rod 8013. The pulling force is transmitted to the counterweight 202 through the cooperation of the first pulley assembly 801 and the second pulley assembly 802. The synchronous magnetic resistance assembly 3 switches the current direction according to the movement direction (clockwise when pulling up and counterclockwise when lowering), providing bidirectional resistance. The legs push backward to tilt the movable plate 502 toward the fixed box 501, compressing the elastic member 5011 in the fixed box 501. At this time, the groove plate 5032 is in close contact with the fixed box 501 to prevent the foot pedal 503 from sliding. At the same time, the leg airbag 604 in the leg fixing frame 603 is periodically inflated and deflated with the up and down movement of the counterweight 202, simulating the muscle pump effect, compressing the venous blood vessels to accelerate blood return. The coordinated training of the hands and legs improves the overall coordination of the body, and the chest expansion enhances the vital capacity. Continuous training for 20 - 30 minutes can significantly improve the cardiopulmonary endurance.

[0060] Application Example 3: Passive training mode The patient lies on his back on the seat cushion 102. At this time, the groove plate 5032 at the bottom of the foot pedal 503 is separated from the fixed box 501, and the foot pedal 503 can slide up and down on the movable plate 502. The motor 701 on the support rod 401 is started, and the output shaft of the motor 701 drives the eccentric wheel 702 to rotate. The eccentric rod 7021 on the eccentric wheel 702 makes an eccentric circular motion, and the swing member 704 slidably connected to the eccentric rod 7021 swings left and right in the liquid chamber 703.

[0061] When the swing member 704 swings to the left, the left cavity space of the liquid chamber 703 is compressed, and the liquid in the chamber is squeezed, increasing the pressure. Under the action of the pressure, the liquid flows through the liquid outlet 7031 of the left cavity into the moving push rod 708 through the connecting pipe 705, pushing the piston rod 7081 to move. The piston rod 7081 drives the telescopic member 706 to elongate through the push rod 7082, thereby driving the push plate 707 to move upward, lifting the foot pedal 503 and driving the legs to move upward.

[0062] Similarly, the pressure in the liquid chamber 703 on the right side decreases, the push rod 7082 on the right side moves downward, driving the internal telescopic member 706 to contract downward, and the foot pedal 503 follows and falls downward under the action of gravity.

[0063] Due to the periodic swinging of the swing member 704, the liquid pressures in the left and right chambers are continuously changed, realizing the up-and-down movement of the two legs. This kind of movement helps to relax the legs after active training, relieve muscle fatigue, consolidate the effect of active training, and is especially suitable for patients in the postoperative recovery period.

[0064] Application Example 4: Leg Venous Blood Vessel Return Assistance Mode Hang the hook 5033 on the foot pedal 503 on the hanging ring 5012 at the top of the fixed box 501, making the legs higher than the head. This posture utilizes the action of gravity, making the position of the legs relatively high, and the blood in the legs is more likely to flow back to the heart under the action of gravity, which helps to accelerate the return of leg venous blood vessels and promote blood circulation.
