Description

Technical Field

[0001] The invention relates to the technical field of rehabilitation training, in particular to a cardiac rehabilitation training device. Background Art

[0002] Cardiac rehabilitation exercise is an important part of cardiac rehabilitation. It is to select appropriate functional activities and exercise methods according to the characteristics of the disease and the patient's cardiac function to guide the patient to train, so as to prevent and treat the disease and promote the recovery of physical and mental functions. It generally refers to long-term, moderate, and continuous chronic exercise, such as walking, jogging, cycling, swimming, climbing stairs, rowing, etc. Heart disease patients can also use training equipment to train their body muscles. Common fitness bikes can simulate cycling training. Heart disease patients can train their lower body by pedaling and turning.

[0003] However, for some patients with heart diseases, the simplest initial training method after rehabilitation is walking, climbing slopes or stairs. This type of rehabilitation training is relatively mild. Due to the limitation of the venue, patients recovering from heart disease are more sensitive to the external air environment, and the venue is also subject to certain restrictions. The treadmill generally provides a very limited circulation environment for patients. Patients are trained according to the speed of the treadmill, but patients may not be able to adapt to the large movements of running. At this time, the treadmill will be subject to a certain degree of limitation, which ultimately leads to limited training and rehabilitation effects for patients.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-Figure 7 A cardiac rehabilitation training device comprises a pedestal 1; a training component 2 for conducting rehabilitation training on patients with cardiac diseases; a display component 3 for displaying the inclination angle of the training component 2; a conversion component 5 for controlling the structural transformation of the training component 2; the training component 2 comprises a driving device, an adjusting device and a manual device; the driving device is used to generate a circular motion platform for providing patients with training.

[0031] In this embodiment, the driving device includes a power element, which is connected to the first shaft 201 through a transmission device, and a pulley 1 203 is fixedly connected to the first shaft 201. The surface of the pulley 1 203 is connected to the pulley 2 204 through a steel belt 205. The axis of the pulley 2 204 is connected to the second shaft 202. A bearing plate 206 is provided 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. The connecting seat 207 is rotatably connected to the second shaft 202. The power element and the transmission device belong to the prior art, and the driving method of the motor and the sprocket can be adopted, but the driving method of the power is not limited, and it only needs to be able to control the rotation of the first shaft 201. The first shaft 201 is driven to rotate, and then the pulley 1 203 on the first shaft 201 drives the pulley 2 204 to rotate through the transmission of the steel belt 205, so that the patient can step on the steel belt 205 and walk. The overall operation is similar to the principle of a "treadmill", which can achieve in-situ inclined walking and climbing, and realize the rehabilitation training of cardiopulmonary function.

[0032] Furthermore, the adjusting device includes a pull shaft 215, both ends of which are connected to the connecting seat 207, a support rod 218 is rotatably connected to the pull shaft 215, a threaded seat 216 is rotatably connected to the bottom of the support rod 218, an adjusting screw 217 is internally threadedly connected to the threaded seat 216, and the adjusting screw 217 is rotatably connected to the bottom of the pedestal 1. A handrail 208 is fixedly connected to the pedestal 1, one end of the handrail 208 is rotatably connected to a connecting shaft 209, one end of the connecting shaft 209 is connected to a gear 1 210, the gear 1 210 is connected to a support rod shaft 219 through gear meshing transmission, and the support rod shaft 219 is transmission-connected to a matching gear 220 at one end of the adjusting screw 217 through a gear. A baffle 211 is fixedly connected to the connecting shaft 209, an arm cover 212 is slidably connected to the connecting shaft 209, one end of the arm cover 212 is fixedly connected to an insertion wheel 214, and an end wheel 213 that cooperates with the insertion wheel 214 is fixedly connected to the connecting shaft 209. The operator puts both hands on the arm cover 212 to provide gripping protection on both sides. If the overall inclination slope needs to be adjusted, the patient can push the arm cover 212 upward with his hand to control the insertion wheel 214 and the end wheel 213 to cooperate with each other. The insertion wheel 214 and the end wheel 213 are integrated by the design of the notch. Through the indirect transmission of the meshing of the gears, the adjustment screw rod 217 is driven to rotate, and then the threaded seat 216 is driven to move left and right by the threaded connection, thereby controlling the tilt angle of the support rod 218 to change to a certain extent, and the connection seat 207 supports the gravity of the top of the entire steel belt 205. At this time, the entire steel belt 205 will rotate slightly with the center of the first axis 201, thereby changing the tilt angle of the steel belt 205, so that the patient can realize the autonomous adjustment of the slope to the slope that he can adapt to. A plurality of rings are provided on the armrest cover 212. The rings are provided to facilitate the patient's hand to exert force, rotate the armrest cover 212, and then realize the autonomous change of the angle.

[0033] Furthermore, the display component 3 includes a fixed frame 302, which is fixed on the pedestal 1. A dial 305 is installed on the fixed frame 302. A pointer 306 is rotatably connected inside the dial 305. The pointer 306 is connected to a pinion 303 through an axis rod. A pressure rod 301 is meshed on the pinion 303. The pressure rod 301 is slidably connected to the inside of the fixed frame 302. 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 to the inside of the fixed frame 302. The display component 3 is provided to provide a display of the tilt angle. When the angle of the steel belt 205 changes, the connecting seat 207 will follow the change and move downward, and then drive the pull shaft 215 to move downward. Then, the pull shaft 215 abuts against the pressure rod 301, which will drive the pressure rod 301 to pull down. Then, the pressure rod 301 will drive the rotation of the pinion 303 through the meshing of the teeth. Then, the pinion 303 drives the rotation of the pointer 306 through the shaft. At this time, the tilt process of the steel belt 205 is converted into a rotation angle change value 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. The positioning plates 503 are fixedly connected with synchronous tooth plates 502. The middle parts of the two synchronous tooth plates 502 are meshed with synchronous gears 501. The synchronous gears 501 are rotatably connected to the bearing plate 206. The pedal device includes a pressure plate 1 505. The bottom of the pressure plate 1 505 is rotatably connected to the steel belt 205. The top of the pressure plate 1 505 is rotatably connected to the pressure plate 2 506. One side of the pressure plate 2 506 is rotatably connected to the pressure plate 3 507. 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. Both sides of the pressure plate 1 505 are rotatably connected to rollers 508. The rollers 508 are slidably connected to the positioning plate 503. When the positioning plate 503 is in Figure 5 position, with the transmission of the steel belt 205, the three hinged pressure plates will be driven to unfold, because 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 to the inclined surface, and then the pressure plate 505 will be stretched open, and the three pressure plates 505 will unfold in a triangle, so a step shape is formed at this time. The multiple pressure plates arranged on the entire steel belt 205 will form steps. At this time, the patient steps on the step body formed by the unfolding of the three pressure plates, so as to realize the transformation of the scene and transform the entire equipment into the structural shape of "climbing stairs".

[0035] In addition, a pull rod 509 is installed on one side of the positioning plate 503, a magnetic strip is installed at the bottom of the synchronous gear plate 502, and the magnetic strip is fixed to the bearing plate 206 by magnetic attraction, and a flat plate 4 is installed on the pedestal 1. The magnetic strip can realize the magnetic attraction positioning of the synchronous gear plate 502, so as to avoid the vibration caused by the rehabilitation training causing the displacement of the synchronous gear plate 502 and the movement of the positioning plate 503, because once the positioning plate 503 moves, it will cause the position of the roller 508 to change when it moves, and finally determine whether the pressing plate 1 505, the pressing plate 2 506 and the pressing plate 3 507 are unfolded. The flat plate 4 is set to provide the patient with a flat standing position at the initial time.

[0036] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0037] The working principle is that when the patient needs to exercise, he needs to initially stand on the flat plate 4, and then control the rotation of the power element to drive the transmission device to operate. The power element and the transmission device belong to the existing technology, and the driving method of the motor and the sprocket can be used to drive the rotation of the first shaft 201. Then the pulley 1 203 on the first shaft 201 drives the rotation of the pulley 2 204 through the transmission of the steel belt 205. Therefore, at this time, the patient can step on the steel belt 205 and walk. The whole is similar to the principle of a "treadmill", which can achieve in-situ inclined walking and climbing, and realize the rehabilitation training of cardiopulmonary function. The operator places both hands on the arm glove 212 to provide gripping protection on both sides. If the overall inclination slope needs to be adjusted, the patient can push the arm glove 212 upward to control the insertion wheel 214 and the end wheel 213 to cooperate with each other. The insertion wheel 214 and the end wheel 213 are combined by the design of the notch. At this time, the patient turns the arm glove 212 to drive the rotation of the connecting shaft 209, and the bottom of the connecting shaft 209 drives the rotation of the support rod shaft 219 through the meshing of the bevel gear, and the gear on the support rod shaft 219 is connected to the support rod shaft 219. Through meshing with the matching gear 220, the adjusting screw 217 is driven to rotate, and then the threaded seat 216 is driven to move left and right by using the threaded connection, thereby controlling the tilt angle of the support rod 218 to change to a certain extent, and the connecting seat 207 supports the gravity of the top of the entire steel belt 205. At this time, the entire steel belt 205 will rotate slightly with the center of the first axis 201, thereby changing the tilt angle of the steel belt 205, so that the patient can achieve autonomous adjustment of the slope to the slope that he can adapt to. During traditional training, the hand force process is to pull the armrest cover 212 downward to slide down, and use the baffle 211 to block and control the limit of the armrest cover 212 sliding down. The set ring is to facilitate the patient's hand force, the rotation of the armrest cover 212, and then achieve autonomous change of the angle. In addition, the normal armrest cover 212 is pulled downward by the patient's hand, so that the control insertion wheel 214 will not cooperate with the end wheel 213. Therefore, only when the patient slides the armrest cover 212 upward on his own initiative can the change of the slope be indirectly controlled. The display assembly 3 is set to provide a display of the tilt angle. When the angle of the steel belt 205 changes, the connecting seat 207 will follow the change and move downward, and then drive the pull shaft 215 to move downward. Then the pull shaft 215 and the pressure rod 301 will contact each other, 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 drives the pointer 306 to rotate through the shaft. At this time, the tilt process of the steel belt 205 is converted into a rotation angle change value for display. The compression spring 304 is set to provide elastic force to the bottom of the pressure rod 301 to always press against the pull shaft 215 when the angle is adjusted in the reverse direction, which can achieve both reverse reset and position limitation.

[0038] The conversion assembly 5 is provided with three pressing plates installed on the steel belt 205, namely, pressing plate 1 505, pressing plate 2 506 and pressing plate 3 507. In fact, the patient actually steps on the three pressing plates. When the positioning plate 503 is in Figure 5 position, with the transmission of the steel belt 205, the three hinged pressure plates will be driven to unfold, because 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 to the inclined surface, and then the pressure plate 505 will be stretched open, and the three pressure plates 505 will unfold in a triangle, so a step shape is formed at this time. The multiple pressure plates arranged on the entire steel belt 205 will form steps. At this time, the patient steps on the step body formed by the unfolding of the three pressure plates, so as to realize the transformation of the scene and transform the entire equipment into the structural shape of "climbing stairs". If the patient pulls the positioning plate 503 outward through the pull rod 509, the movement of the synchronous tooth plate 502 will be synchronously driven, and then the relative meshing of the synchronous gear 501 will drive the two synchronous tooth plates 502 to move relative to each other, thereby controlling the two positioning plates 503 to move outward a short distance. At this time, the transmission process of the steel belt 205 drives the movement of the pressure plate 505, and 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 be unfolded at this time, but will be presented on the surface of the steel belt 205 in an interlaced folding manner. At this time, a small slope will be formed, and the patient can step on the folded small slope to avoid the patient's shoe soles sliding when walking directly on the steel belt 205. It is similar to providing small steps to facilitate the patient's walking exercise.
