Description

Technical Field

[0001] This invention relates to the field of rehabilitation training technology, specifically to a cardiac rehabilitation training device. Background Technology

[0002] Cardiac rehabilitation exercises are an important part of cardiac rehabilitation. They involve selecting appropriate functional activities and exercise methods based on the characteristics of the disease and the patient's cardiac function to guide training, thereby preventing and treating the disease and promoting the recovery of physical and mental function. Generally, these refer to long-term, moderate, and continuous chronic exercise, such as walking, jogging, cycling, swimming, climbing stairs, and rowing. Heart disease patients can also use training equipment to train their muscle groups. Common exercise bikes can simulate cycling training; heart disease patients can train their lower body by pedaling and rotating their feet.

[0003] However, currently, for some patients with heart disease, the simplest initial training method after rehabilitation is walking, climbing hills, or climbing stairs. This type of rehabilitation training is relatively gentle. Due to space limitations, heart disease rehabilitation patients are quite sensitive to the external air environment, and the space is also limited. Treadmills generally provide patients with very limited circulation environment, and the training is based on the speed of the treadmill. However, patients may not be able to adapt to the large movements of running, which limits the effectiveness of the treadmill and ultimately results in limited rehabilitation effects for the patients. Therefore, a cardiac rehabilitation training device is proposed to solve the above-mentioned problems. Summary of the Invention

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a cardiac rehabilitation training device with the following beneficial effects:

[0018] 1. This cardiac rehabilitation training equipment, through its designed training components, enables rehabilitation training for patients with heart disease. The entire training device provides adjustable inclines for patients to perform walking training. Compared to treadmills, this training method is more diversified because the intensity of walking training increases with incline adjustment, gradually improving the patient's cardiopulmonary function. Furthermore, running is unnecessary, as running can be too stressful for patients in the initial stages of rehabilitation. The adjustable incline angle allows for adaptive adjustments to facilitate cardiopulmonary function training, ultimately improving the patient's rehabilitation training effect. The entire device can be installed indoors, effectively avoiding interference from external air.

[0019] 2. This cardiac rehabilitation training equipment, through its conversion components, can control and change the overall training method, transforming ramp-style training into stair-style structural training, thereby increasing the diversity of equipment training to cope with patients with different symptom intensities, making the rehabilitation training process more tailored to the patient.

[0020] 3. This cardiac rehabilitation training device, through its display components, can display changes in the tilt angle, thereby providing patients with certain visual reminders and facilitating their subsequent adjustment of the tilt slope, making it easier for them to judge whether to increase or decrease the slope.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-7 A cardiac rehabilitation training device includes a base 1; a training component 2 for rehabilitation training of patients with cardiac diseases; a display component 3 for displaying the tilt angle of the training component 2; and a conversion component 5 for controlling the structural conversion of the training component 2. The training component 2 includes a drive device, an adjustment device, and a manual device. The drive device is used to generate a loop motion platform for patients to train.

[0031] In this embodiment, the driving device includes a power element, which is connected to a first shaft 201 via a transmission device. A pulley 203 is fixedly connected to the first shaft 201. A second pulley 204 is driven to the surface of the pulley 203 via a steel belt 205. A second shaft 202 is connected to the axis of the second pulley 204. A bearing plate 206 is disposed at the center of the steel belt 205. One end of the bearing plate 206 is rotatably connected to the first shaft 201, and the other end of the bearing plate 206 is connected to a connecting seat 207, which is rotatably connected to the second shaft 202. The power element and transmission device are existing technologies and can be driven by a motor and sprockets, but the type of power drive is not limited, as long as it can control the rotation of the first shaft 201. The rotation of the first shaft 201 is driven by the first pulley 203 on the first shaft 201, which then drives the rotation of the second pulley 204 through the transmission of the steel belt 205. At this time, the patient can step and walk on the steel belt 205, which is similar to the principle of a "treadmill". This allows for in-place inclined walking and climbing, and enables cardiopulmonary rehabilitation training.

[0032] Furthermore, the adjustment device includes a pull shaft 215, with both ends of the pull shaft 215 connected to the connecting seat 207. A support rod 218 is rotatably connected to the pull shaft 215, and a threaded seat 216 is rotatably connected to the bottom of the support rod 218. An adjusting screw 217 is internally threaded into the threaded seat 216 and rotatably connected to the bottom of the base 1. A handrail 208 is fixedly connected to the base 1, with a connecting shaft 209 rotatably connected to one end of the handrail 208. A gear 210 is connected to one end of the connecting shaft 209, and a support rod shaft 219 is connected to the gear 210 through gear meshing. The support rod shaft 219 is connected to the gear 220 that meshes with the adjusting screw 217. A baffle 211 is fixedly connected to the connecting shaft 209, and a handgrip 212 is slidably connected to the connecting shaft 209. An insertion wheel 214 is fixedly connected to one end of the handgrip 212, and an end wheel 213 that mates with the insertion wheel 214 is fixedly connected to the connecting shaft 209. The operator's hands rest on the handgrip 212 for lateral gripping and protection. If the overall tilt angle needs to be adjusted, the patient can push the handgrip 212 upwards to control the insertion wheel 214 and the end wheel 213 to engage. The groove design allows the insertion wheel 214 and the end wheel 213 to fit together. Through indirect transmission via gear meshing, the adjusting screw 217 rotates, and then, through the threaded connection, the threaded seat 216 moves left and right, thereby controlling the tilt angle of the support rod 218 to a certain extent. The connecting seat 207 supports the weight of the top of the entire steel belt 205. At this time, the entire steel belt 205 will rotate slightly around the center of the first axis 201, thus changing the tilt angle of the steel belt 205. Therefore, the patient can achieve autonomous adjustment of the slope to a suitable level. The armrest 212 is equipped with multiple rings. These rings are designed to facilitate the patient's hand support and rotation of the armrest 212, thereby achieving autonomous angle adjustment.

[0033] Furthermore, the display component 3 includes a mounting bracket 302, which is fixed to the base 1. A dial 305 is mounted on the mounting bracket 302, and a pointer 306 is rotatably connected inside the dial 305. The pointer 306 is connected to a pinion 303 via a shaft, and a pressure rod 301 meshes with the pinion 303. The pressure rod 301 is slidably connected inside the mounting bracket 302, and the bottom of the pressure rod 301 abuts against the pull shaft 215. A compression spring 304 is connected to the pressure rod 301, and the compression spring 304 is connected inside the mounting bracket 302. The display component 3 is provided to display the tilt angle. When the angle of the steel strip 205 changes, the connecting seat 207 will change accordingly and move downward, which will then drive the pull shaft 215 to move downward. Then, the pull shaft 215 will abut against the pressure rod 301, which will drive the pressure rod 301 to pull down. Then, the pressure rod 301 will drive the pinion 303 to rotate through the meshing of the teeth. Then, the pinion 303 will drive the pointer 306 to rotate through the shaft. At this time, the tilting process of the steel strip 205 is converted into the value of the change in the rotation angle for display.

[0034] In addition, the conversion assembly 5 includes a pedal device and a shifting device. The shifting device includes two positioning plates 503, each with a synchronous gear plate 502 fixedly connected to it. A synchronous gear 501 meshes with the middle of the two synchronous gear plates 502, and the synchronous gear 501 is rotatably connected to the support plate 206. The pedal device includes a pressure plate 1 505, the bottom of which is rotatably connected to the steel belt 205. A pressure plate 2 506 is rotatably connected to the top of the pressure plate 1 505. A pressure plate 3 507 is rotatably connected to one side of the pressure plate 206, and one side of the pressure plate 3 507 is rotatably connected to the steel belt 205. A pressing groove 504 is provided on one side of the positioning plate 503. Rollers 508 are rotatably connected to both sides of the pressure plate 1 505 and are slidably connected to the positioning plate 503. When the positioning plate 503 is in position... Figure 5 When in position, as the steel belt 205 is driven, the three hinged pressure plates will unfold. The rollers 508 on both sides of the pressure plate 505 will slide from the inclined surface of the positioning plate 503 until they slide onto the inclined surface. Then the pressure plate 505 will be opened, and the three pressure plates 505 will unfold in a triangle shape, thus forming a step shape. The multiple pressure plates set on the entire steel belt 205 will form a series of steps. At this time, the patient steps on the steps formed by the unfolded pressure plates, thereby realizing the scene transformation and turning the entire device into a "staircase" structure.

[0035] In addition, a pull rod 509 is installed on one side of the positioning plate 503, and a magnetic strip is installed on the bottom of the synchronous toothed plate 502. The magnetic strip is magnetically fixed to the support plate 206, and a flat plate 4 is installed on the base 1. The magnetic strip enables the synchronous toothed plate 502 to be magnetically positioned, preventing the vibration generated during rehabilitation training from causing the synchronous toothed plate 502 to shift and thus moving the positioning plate 503. If the positioning plate 503 shifts, the roller 508 will change position, ultimately affecting whether the pressure plate 1 505, pressure plate 2 506, and pressure plate 3 507 unfold. The flat plate 4 is provided to provide the patient with an initial flat standing position.

[0036] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0037] The working principle is as follows: First, when the patient needs to exercise, he / she needs to stand on the flat plate 4. Then, the rotation of the power element is controlled to drive the transmission device. The power element and transmission device are existing technologies and can be driven by a motor and sprocket to drive the rotation of the first shaft 201. Then, the pulley 203 on the first shaft 201 drives the rotation of the second pulley 204 through the transmission of the steel belt 205. So at this time, the patient can step and walk on the steel belt 205. The whole is similar to the principle of a "treadmill" to achieve in-place inclined walking and climbing, and to achieve cardiopulmonary function rehabilitation training. The operator's hands rest on the handgrip 212, providing lateral grip and protection. If the overall tilt needs adjustment, the patient can push the handgrip 212 upwards to engage the insertion wheel 214 and end wheel 213. The slot design allows the insertion wheel 214 and end wheel 213 to align. When the patient rotates the handgrip 212, it drives the connecting shaft 209 to rotate. The bottom of the connecting shaft 209, through the meshing of bevel gears, drives the rotation of the support shaft 219. The gears on the support shaft 219... Through the meshing of the gear 220, the adjusting screw 217 is driven to rotate. Then, through the threaded connection, the threaded seat 216 moves left and right, thereby controlling the tilt angle of the support rod 218 to a certain extent. The connecting seat 207 supports the weight of the top of the entire steel belt 205. At this time, the entire steel belt 205 will rotate slightly around the center of the first axis 201, thereby changing the tilt angle of the steel belt 205. Therefore, the patient can achieve autonomous adjustment of the slope to a slope that he / she can adapt to. In traditional training, the hand exertion process is to pull the armrest 212 down, and the baffle 211 is used to control the downward movement of the armrest 212. The ring is designed to facilitate the patient's hand exertion and rotation of the armrest 212, thereby achieving autonomous angle change. Furthermore, the normal handgrip 212 is pulled downwards by the patient's hand, thus preventing the insertion wheel 214 from engaging with the end wheel 213. Therefore, only when the patient voluntarily slides the handgrip 212 upwards will the slope change be indirectly controlled. The display component 3 is provided to display the tilt angle. When the angle of the steel belt 205 changes, the connecting seat 207 will follow suit and move downwards, which in turn drives the pull shaft 215 downwards. The pull shaft 215 then abuts against the pressure rod 301, causing the pressure rod 301 to pull down. The pressure rod 301, through the meshing of its teeth, drives the pinion 303 to rotate. The pinion 303 then drives the pointer 306 to rotate via the shaft, thus converting the tilting process of the steel belt 205 into a value of the change in rotation angle for display. The compression spring 304 provides elasticity to the bottom of the pressure rod 301 during reverse angle adjustment, ensuring it always rests against the pull shaft 215, achieving both reverse reset and position limitation.

[0038] The conversion component 5 consists of three pressure plates installed on the steel belt 205: pressure plate one 505, pressure plate two 506, and pressure plate three 507. The patient actually steps on these three pressure plates. When the positioning plate 503 is in position... Figure 5 When in position, as the steel belt 205 is driven, the three hinged pressure plates will unfold. The rollers 508 on both sides of the pressure plate 505 will slide from the inclined surface of the positioning plate 503 until they slide onto the inclined surface. Then the pressure plate 505 will be opened, and the three pressure plates 505 will unfold in a triangle shape, thus forming a step shape. The multiple pressure plates set on the entire steel belt 205 will form a series of steps. At this time, the patient steps on the steps formed by the unfolded pressure plates, thereby realizing the scene transformation and turning the entire device into a "staircase" structure. If the patient pulls the positioning plate 503 outward via the lever 509, it will simultaneously drive the synchronous toothed plate 502 to move. Then, through the relative meshing of the synchronous gear 501, it will drive the two synchronous toothed plates 502 to move relative to each other, thereby controlling the two positioning plates 503 to move outward a small distance. At this time, during the transmission process of the steel belt 205, when the pressure plate 505 is moved, the roller 508 will enter the interior of the pressing groove 504 on the inclined surface of the positioning plate 503. Therefore, the three pressure plates will not unfold at this time, but will be presented in an alternating folded manner on the surface of the steel belt 205, thus forming a small slope. When the patient steps on the folded small slope, it can prevent the patient from slipping on the steel belt 205 directly, similar to providing small steps to facilitate the patient's walking exercise.
