Description

Technical Field

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

[0002] The heart is one of the most important organs in the human body. The causes of heart disease are very complex, and it is a relatively serious disease. After surgery, heart disease patients must undergo rehabilitation training to recover quickly. This is indispensable. Good rehabilitation training will greatly promote the improvement of the condition and is also very beneficial to the patient's physical condition. Cardiac rehabilitation refers to a combination of various coordinated and purposeful intervention measures, such as rehabilitation assessment, exercise training, diet and behavior, and medical compliance. Among these, patients often promote blood circulation through exercise, thereby promoting the patient's own cardiac rehabilitation progress.

[0003] Patent application number (CN202120015353.4) discloses "an auxiliary device for cardiac rehabilitation training," comprising a base plate and a pad. A clamping plate is fixedly connected to the lower surface of the base plate, and a fastening bolt is movably connected to the lower surface of the clamping plate. A support column is fixedly connected to the upper surface of the base plate. A rotating rod is movably connected to one side of the support column, and a foot pedal is movably connected to one side of the rotating rod. An adjusting nut is movably connected to the front of the support column. This cardiac rehabilitation training auxiliary device, through the coordinated arrangement of the base plate, clamping plate, and fastening bolt, allows the clamping plate to be clamped to one end of the patient's bed after the fastening bolt is tightened. Even if the patient cannot get out of bed, they can still exercise in bed. The rotating rod and foot pedal allow for aerobic training while the patient is lying in bed. The adjusting nut at one end of the support column allows for adjustment of the resistance of the rotating rod according to the patient's recovery speed in the later stages of recovery. However, existing rehabilitation training devices have limited functionality and are inconvenient for simultaneous rehabilitation training of the upper and lower limbs. Targeting only the upper or lower limbs cannot provide effective cardiac rehabilitation training. Furthermore, existing cardiac rehabilitation training devices have limited usage methods and cannot be flexibly applied to patients at different stages of cardiac rehabilitation, resulting in poor effectiveness. Therefore, we propose an intelligent cardiac rehabilitation training auxiliary device to solve the above problems. Summary of the Invention

The second driven wheel is rotatably connected inside the second movable groove, and the second driven wheel meshes with the second driving wheel.

[0008] Preferably, the linkage assembly includes a first fixed rod, a first pulley, a connecting rope, and collars. The first fixed rod is threadedly connected to the outer surface of the first support rod, and the first pulley is rotatably connected to the surface of the first fixed rod. The connecting rope is movably connected to the inner side of the first pulley, and collars are fixedly connected to the upper and lower ends of the connecting rope. The two sets of collars are respectively sleeved on the rotating shafts of the pedal and the handle.

[0009] Preferably, both the first driven wheel and the second driven wheel are provided with an adjustment component. The adjustment component includes a positioning ring, a water inlet pipe, a pipe cover, and a piston. The front and rear ends of the first driven wheel and the second driven wheel are fixedly connected with positioning rings. A water inlet pipe is connected inside one set of positioning rings.

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-5 An embodiment of the present invention provides an intelligent cardiac rehabilitation training auxiliary device, including a support frame 1, a first support rod 2 fixedly connected to the top of the support frame 1, a second support rod 3 installed on the right side of the support frame 1, and a seat cushion 4 connected to the upper end of the second support rod 3. The patient can also remove the second support rod 3 and the seat cushion 4 and place the device by the bedside for convenient rehabilitation exercises. The support frame 1 is provided with a lower limb exercise mechanism 5, the first support rod 2 is provided with an upper limb exercise mechanism 6, and a linkage component 7 is provided between the lower limb exercise mechanism 5 and the upper limb exercise mechanism 6. This device solves the problems of limited functionality of existing rehabilitation training devices, which make it inconvenient to perform rehabilitation training on both the upper and lower limbs simultaneously, and the limited usage of existing cardiac rehabilitation training devices, which cannot be flexibly applied to patients at different stages of cardiac rehabilitation, through the linkage component 7 set between the lower limb exercise mechanism 5 and the upper limb exercise mechanism 6.

[0022] Furthermore, the lower limb exercise mechanism 5 includes a first driving wheel 502, a first fixed shaft 503, a first connecting rod 504, a pedal 505, and a first driven wheel 506. The support frame 1 has a first movable groove 501 inside, with the first driving wheel 502 connected to the center of the first movable groove 501. The first fixed shaft 503 is installed at the center of the first driving wheel 502. The first connecting rod 504 is fixedly connected to both ends of the first fixed shaft 503, and the pedal 505 is fixedly installed at the other end of the first connecting rod 504. The first driven wheel 506 is rotatably connected inside the first movable groove 501, and the first driven wheel 506 meshes with the first driving wheel 502. Figure 2 As shown, this structure is used by the user to place their foot on the pedal 505 and fix it with the Velcro on the outside, and then continuously step on the pedal 505, thereby driving the first drive wheel 502 to rotate. Under the mutual meshing of the first drive wheel 502 and the first driven wheel 506, the first driven wheel 506 is driven to rotate, thus exercising the legs.

[0023] Furthermore, the upper limb exercise mechanism 6 includes a second driving wheel 602, a second fixed shaft 603, a second connecting rod 604, a handle 605, and a second driven wheel 606. A second movable groove 601 is provided at the top of the first support rod 2. The second driving wheel 602 is rotatably connected inside the second movable groove 601. The second fixed shaft 603 is installed at the center of the second driving wheel 602. The second connecting rod 604 is fixedly connected to both ends of the second fixed shaft 603. A handle 605 is fixedly connected to the other end of the second connecting rod 604. The second driven wheel 606 is rotatably connected inside the second movable groove 601, and the second driven wheel 606 meshes with the second driving wheel 602. Figure 2 As shown, this structure is used by the user to hold the handle 605 with both hands, and drive the second drive wheel 602 to rotate through the second connecting rod 604 and the second fixed shaft 603. Under the action of the second drive wheel 602 and the second driven wheel 606 meshing with each other, the second driven wheel 606 rotates, thus exercising the hands.

[0024] Furthermore, the linkage component 7 includes a first fixed rod 701, a first pulley 702, a connecting rope 703, and collars 704. The first fixed rod 701 is threadedly connected to the outer surface of the first support rod 2. The first pulley 702 is rotatably connected to the surface of the first fixed rod 701. The connecting rope 703 is movably connected to the inner side of the first pulley 702. Collars 704 are fixedly connected to the upper and lower ends of the connecting rope 703. The two sets of collars 704 are respectively sleeved on the rotating shafts of the pedal 505 and the handle 605. Figure 4As shown, this structure is used to connect the pedal 505 and the handle 605 via the connecting rope 703 on the surface of the first pulley 702. When the handle 605 or the pedal 505 is rotated, the connecting rope 703 is pulled to move along the first pulley 702, thereby saving physical strength and meeting the exercise intensity in the early stage of rehabilitation.

[0025] Furthermore, both the first driven wheel 506 and the second driven wheel 606 are equipped with an adjustment assembly 8. The adjustment assembly 8 includes a positioning ring 801, a water inlet pipe 802, a pipe cover 803, and a piston 804. The front and rear ends of the first driven wheel 506 and the second driven wheel 606 are fixedly connected to the positioning ring 801. The positioning ring 801 stabilizes the first driven wheel 506 and the second driven wheel 606 within the support frame 1 and the first support rod 2 for rotation. The water inlet pipe 802 is connected inside one set of positioning rings 801, and the top end of the water inlet pipe 802 is threadedly connected to the pipe cover 803. The piston 804 is inserted inside the other set of positioning rings 801. A miniature water pump is installed inside the first driven wheel 506 and the second driven wheel 606. The external water pipe is located at the positioning ring 801 on the other side. When the piston 804 is opened, the internal water source is discharged from here. Figure 5 As shown, this structure is used to add an appropriate amount of water through the water inlet pipe 802 into the first driven wheel 506 or the second driven wheel 606 by rotating the pipe cover 803, thereby increasing resistance and increasing the amount of exercise, and can adjust the intensity of the patient's exercise.

[0026] Furthermore, a first display screen 9 is installed on the top left side of the first support rod 2, and a second display screen 10 is installed on the top right side of the first support rod 2. For example... Figure 3 As shown, the structure is designed with a first display screen 9 and a second display screen 10 facing opposite directions. The second display screen 10 is used to guide the user to use the device correctly, while the first display screen 9 is used by medical staff or family members to view the exercise effect and physical condition. It connects to a monitor to display heart rate, oxygen saturation, etc., so as to avoid the exercise data and physical condition causing psychological impact on the user. It also uses data to evaluate the feasibility of preventing limb complications after coronary angiography and performs AI analysis of heart failure to judge the exercise effect.

[0027] Furthermore, a second fixed rod 706 is threadedly connected to the upper end of the first fixed rod 701 on the surface of the first support rod 2. The second fixed rod 706 is positioned outside the movement trajectory of the second connecting rod 604 and the handle 605, while maintaining hand clearance to allow for smooth hand passage. A second pulley 707 is rotatably connected to the surface of the second fixed rod 706, and a connecting rope 703 is wound around the surface of the second pulley 707 and connected to the handle 605. Figure 4 As shown, this structure is used to guide the connecting rope 703 stably through the second pulley 707 by setting the second fixed rod 706, so that the connecting rope 703 can move stably.

[0028] Furthermore, the pivots of the pedal 505 and handle 605 are provided with slots 705, the inner diameter of which is adapted to the collar 704. Figure 4 As shown, the structure is designed with a slot 705 to facilitate the insertion of the collar 704 into the slot 705, thereby ensuring a stable connection between the pedal 505 and the handle 605 and making it convenient to use.

[0029] Working principle: such as Figure 1 As shown, when using the cushion, adjust the seat 4 to a suitable height, and the user sits on the cushion 4, as follows: Figure 2 and Figure 4 As shown, in the initial stage of rehabilitation, the loop 704 at the end of the connecting rope 703 on the surface of the first pulley 702 is attached to the pedal 505 and the handle 605 for connection, so that the loop 704 is engaged in the slot 705. The user places their foot on the pedal 505 and secures it with the Velcro on the outside, holds the handle 605 with both hands, and then continuously steps on the pedal 505, thereby driving the first driving wheel 502 to rotate. Under the mutual meshing of the first driving wheel 502 and the first driven wheel 506, the first driven wheel 506 is driven to move forward. Rotation exercises the legs. When the handle 605 or pedal 505 is rotated, the connecting rope 703 is pulled and moved along the first pulley 702. This, through the second connecting rod 604 and the second fixed shaft 603, drives the second driving wheel 602 to rotate. Under the mutual meshing of the second driving wheel 602 and the second driven wheel 606, the second driven wheel 606 rotates, exercising the hands. In the middle stage of rehabilitation, the linkage component 7 can be removed, allowing for flexible selection of training for the patient's upper and lower limbs separately. In the later stage of rehabilitation, such as... Figure 5 As shown, by rotating the tube cover 803, an appropriate amount of water is added through the water inlet pipe 802 into the first driven wheel 506 or the second driven wheel 606 to increase resistance and increase the amount of exercise. This can adjust the intensity of the patient's exercise and meet the exercise needs. The above is the complete working principle of the present invention.

[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
