[0002] Heart failure is myocardial damage caused by any reason such as myocardial infarction, cardiomyopathy, hemodynamic overload, inflammation, etc., which causes changes in myocardial structure and function, and finally leads to poor ventricular pumping or filling function. The main clinical manifestations are dyspnea, fatigue and fluid retention. Chronic heart failure refers to a persistent state of heart failure, which can be stable, worsening or decompensated. The goal of treating heart failure is not only to improve symptoms and improve quality of life, but also to target the mechanism of myocardial remodeling, delay and prevent the development of myocardial remodeling, and reduce the hospitalization and mortality rate of heart failure.

[0003] For patients with heart failure, when formulating a rehabilitation exercise training plan, it is necessary to fully consider the patient's condition, physical condition, previous experience in physical exercise, and psychological state, and formulate a rehabilitation exercise training plan for them. The exercise methods for patients with heart failure are mainly aerobic exercise, such as walking, cycling, swimming, climbing stairs, etc. Each exercise time is preferably 30-60 minutes, including warm-up exercises for 10-15 minutes, aerobic training for 20-35 minutes, and relaxation exercises for 5-10 minutes; among the existing rehabilitation training methods for patients with chronic heart failure, walking is the most commonly used training method, and when doing walking training, patients can choose a home treadmill for slow walking, but due to long-term heart failure, patients find it difficult to exercise with a large load, and even difficult to stand for a long time. Therefore, a sit-to-stand rehabilitation training instrument for patients with chronic heart failure is first proposed for patients to do aerobic exercise. Utility Model Content

[0024] A rehabilitation training instrument for patients with chronic heart failure, such as Figure 1-Figure 3 As shown, it comprises a seat 1, a training mechanism 2 arranged on the seat 1, and a supporting mechanism 4 for supporting the training mechanism 2;

[0025] The training mechanism 2 includes a rotating shaft 21 rotatably connected to the seat 1, a swing block 22 is fixedly connected to the middle of the rotating shaft 21, a connecting block 23 is provided on the swing block 22, a rotating member 24 is rotatably connected to the connecting block 23, and pedals 25 are rotatably connected to both ends of the rotating member 24. The training mechanism 2 also includes an adjustment component 26 for adjusting the rotation angle of the swing block 22, and the adjustment component 26 includes a turbine 261 fixedly connected to the rotating shaft 21. A bracket 262 is provided, and a rotating shaft 263 is rotatably connected to the bracket 262, and a worm 264 is fixedly connected to the rotating shaft 263, and the worm 264 is coupled to the turbine 261. A first rotating handle 265 in the shape of a straight line is fixedly connected to the end of the rotating shaft 263 away from the worm 264. The seat 1 includes two supporting legs 11 and a seat cushion 12 connected between the two supporting legs 11, a backrest 13 is provided on the seat cushion 12, and an armrest 14 is provided between the backrest 13 and the seat cushion 12.

[0026] It can be understood that when a patient needs to use the chronic heart failure patient rehabilitation training instrument, the medical staff can first adjust the training mechanism 2 according to the patient's body shape. Specifically, the medical staff can rotate the first rotating handle 265, the first rotating handle 265 drives the worm 264 to rotate, the worm 264 drives the turbine 261 to rotate, the turbine 261 drives the rotating shaft 21 to rotate, the rotating shaft 21 drives the swing block 22 to rotate, the swing block 22 drives the connecting block 23 to rotate, the connecting block 23 drives the rotating member 24 to rotate, the rotating member 24 drives the foot pedal 25 to rotate, and the The curvature of the foot pedal 25 can be adjusted to accommodate patients of different body shapes. At the same time, the self-locking effect can be achieved through the cooperation of the turbine 261 and the worm gear 264, so that the patient can operate the training mechanism 2 more stably. Then the patient can sit on the seat cushion 12, hold the armrests 14 with both hands, step on the foot pedal 25 with both feet, and then step on the foot pedal 25 to rotate the rotating part 24, thereby performing aerobic exercise to achieve the effect of rehabilitation training. When the patient performs aerobic exercise, the support mechanism 4 can support the connecting block 23, making the connecting block 23 more stable and increasing its service life.

[0027] like Figure 5-Figure 6 As shown, the supporting mechanism 4 includes a slide rail 41 arranged between two supporting legs 11, a first slider 43 is slidably connected to the slide rail 41, a support 42 is arranged on the connecting block 23, a rocker rod 44 is rotatably arranged between the support 42 and the first slider 43, a pushing component 45 for supporting the first slider 43 is arranged on the slide rail 41, the pushing component 45 includes a second slider 452 slidably connected to the slide rail 41 and a screw 451 threadedly connected to the slide rail 41, the screw 451 is rotatably connected to the second slider 452, and a second rotating handle 453 in the shape of a cross is fixedly connected to the end of the screw 451 away from the second slider 452.

[0028] It can be understood that after the medical staff adjusts the curvature of the foot pedal 25 to adapt to the operator's body shape, the medical staff can operate the support mechanism 4 so that the support mechanism 4 supports the connecting block 23. Specifically, when the connecting block 23 rotates, it will drive the support 42 to rotate, and the rotation of the support 42 drives the rocker arm 44 to rotate, and the rocker arm 44 drives the first slider 43 to slide along the slide rail 41. After the medical staff adjusts the foot pedal 25, that is, after the connecting block 23 stops moving, the medical staff can rotate the second rotating handle 453, and the second rotating handle 453 drives the screw 451 to rotate, and the rotation of the screw 451 drives the second slider 452 to move, thereby the medical staff can move the second slider 452 in a direction close to the first slider 43, so that the second slider 452 contacts the first slider 43, so that the second slider 452 supports the first slider 43, and thus the supporting effect of the connecting block 23 is achieved through the support mechanism 4, so that when the patient is training, the life of the training mechanism 2 is increased.

[0029] like Figure 4 As shown, the connecting block 23 is slidably connected to the swing block 22, and the rehabilitation training instrument also includes an adjusting mechanism 3 for adjusting and fixing the connecting block 23. The adjusting mechanism 3 includes a plurality of clamping holes 33 opened on the connecting block 23. A clamping pin 31 is slidably connected to the swing block 22, and a spring 32 is arranged between the clamping pin 31 and the swing block 22. When the clamping pin 31 is located in the clamping hole 33, the connecting block 23 is fixed.

[0030] When the length of the connecting block 23 needs to be adjusted, the operator can first pull the latch pin 31, the spring 32 is stretched, and the latch pin 31 will no longer be stuck in the hole 33. Then the operator can slide the connecting block 23 according to the situation. After adjusting the connecting block 23, the operator can release the latch pin 31, and the spring 32 will reset to drive the latch pin 31 to be stuck in the hole 33 again, thereby fixing the connecting block 23.

[0031] To summarize, by rotating the first rotating handle 265, the first rotating handle 265 drives the worm 264 to rotate, the worm 264 drives the turbine 261 to rotate, the turbine 261 drives the rotating shaft 21 to rotate, the rotating shaft 21 drives the swing block 22 to rotate, the swing block 22 drives the connecting block 23 to rotate, the connecting block 23 drives the rotating member 24 to rotate, and the rotating member 24 drives the foot pedal 25 to rotate, thereby the curvature of the foot pedal 25 can be adjusted to adapt to patients of different body shapes, and at the same time, the self-locking effect can be achieved through the cooperation of the turbine 261 and the worm 264. The patient can sit on the cushion 12, hold the armrests 14 with both hands, and step on the foot pedals 25 with both feet, and perform aerobic exercise to achieve the effect of rehabilitation training, thereby enabling the patient to perform rehabilitation training in a sitting position.
