[0002] A rehabilitation exercise bike is a fitness equipment specifically designed to evaluate and improve the cardiopulmonary function of users. Currently, most rehabilitation exercise bikes can adjust the height of the seat and armrests according to patients of different heights. When patients are undergoing rehabilitation training, they need to place their hands on the armrests to maintain body balance. Since the shoulder widths of different patients vary, when the width of the armrests matches the shoulder width of the patient, the patient can better maintain body balance and reduce shaking and instability. However, existing rehabilitation exercise bikes cannot be adaptively adjusted according to the shoulder widths of different patients, which not only causes discomfort to patients during use but also poses a risk of patients falling.

[0003] Meanwhile, after exercising for a period of time, patients usually gradually feel fatigued. After fatigue, the body will unconsciously lean forward or backward, thus affecting the riding posture, causing muscle tension in other parts, increasing the workload of the heart, and thus affecting the accuracy of heart rate test data.

[0033] The connecting component includes a fixing rod 101, a folding tube 102 and a connecting ball 103; two symmetrically arranged fixing rods 101 are fixedly connected to the armrest 5; and each fixing block 6 is fixedly connected to the adjacent fixing rod 101; a connecting ball 103 is fixedly connected to one side of each grip 8 close to the fixing rod 101; a folding tube 102 is fixedly connected to each connecting ball 103, and each folding tube 102 is fixedly connected to the adjacent armrest 5, and each folding tube 102 is made of an elastic deformation material.

[0035] A rubber ring 8002 is provided on each flow groove 8001 of the grip 8.

[0036] It further includes a plugging block 201 and a mounting ring 202; the plugging block 201 is slidably connected to the side of the rear grip 8 away from the connecting ball 103; two symmetrically arranged front and rear mounting rings 202 are connected to the rear grip 8; a convex portion 20101 is provided on the plugging block 201, and the convex portion 20101 can slide in the groove formed between the mounting ring 202 and the adjacent grip 8; a connecting portion 20102 is provided on the plugging block 201.

[0037] Existing rehabilitation exercise bikes cannot be adjusted according to the shoulder widths of different patients, which will not only make patients feel uncomfortable during use, but also pose a risk of patients falling. At the same time, after the patients become weak, their bodies will unconsciously lean forward or backward, thus affecting the riding posture and reducing the accuracy of heart rate test data.

[0038] The working steps of this embodiment are as follows:

[0039] First, according to the shoulder width of the patient, move the adjacent first connecting blocks 7 on the fixing block 6 respectively, so that the first connecting blocks 7 drive the adjacent grips 8 to move together. At this time, the folding tube 102 contracts or extends following the movement of the grip 8 until the distance between the two grips 8 matches the shoulder width of the patient. Then, press down the limiting rod 7001 on the first connecting block 7 to insert the limiting rod 7001 into the limiting hole 6001 of the adjacent fixing block 6, so as to fix the positions of the first connecting block 7 and the grip 8; by driving the adjacent grips 8 to move through the first connecting block 7, the distance between the two grips 8 is adjusted to adapt to the shoulder widths of different patients, enhancing the balance of the patient during the exercise process. At the same time, an appropriate distance between the grips 8 can help the patient maintain a correct sitting posture and reduce muscle tension and joint pressure caused by improper postures.

[0040] Next, manually pass the wiring 9001 of the pulse oximeter 9 through the limit ring 5001 on the armrest 5, and neatly restrict the wiring 9001 to one side of the armrest 5 to prevent the patient from squeezing the wiring 9001 during cycling, which may cause the pulse oximeter 9 to fall off the patient's finger, avoiding affecting the patient's test data. Then, adjust the armrest 5 and the seat height of the pedal body 1. Next, the patient sits on the seat, clips the pulse oximeter 9 on one finger, and installs and clips other test instruments. The patient holds the handlebar 8 with both hands. Then, according to the patient's physical condition, start the resistance source 2, and adjust the resistance of the pedal on the pedal body 1 by changing the magnetic field strength between the internal magnet and the flywheel, so as to adjust the exercise difficulty of the patient, start cycling, and record data through the data analysis module 3.

[0041] As the patient exercises, the body gradually heats up. For some high-intensity rehabilitation training, the patient may even sweat all over. When the patient's hands sweat, it will cause the skin surface to be wet, which will affect the contact between the pulse oximeter 9 and the skin, making the pulse oximeter 9 unable to stably adhere to the skin and affecting the accuracy of the data. To solve the above problems, after the patient exercises for a period of time, start the external pump, so that the air flow enters the adjacent folding tube 102 through the armrest 5, then passes through the through hole 10301 of the connecting ball 103, and finally sprays from the flow groove 8001 of the handlebar 8 to the patient's hand, thereby reducing the heat accumulation between the patient's hand and the handlebar 8, keeping the patient's hand in a relatively cool state, and then improving the clamping stability of the pulse oximeter 9. At the same time, the rubber ring 8002 increases the gap between the patient's hand and the handlebar 8, promotes air circulation, and further improves the heat dissipation effect of the flow groove 8001 on the patient's hand. Moreover, the rubber ring 8002 will increase the friction between the patient's hand and the handlebar 8, improving the stability and comfort of the patient's grip.

[0042] After the patient exercises for a long time, they will gradually feel fatigued, and the body will unconsciously lean forward or backward. When the patient leans forward or backward, the center of gravity of the body will move to the hands or the whole body will tilt backward, thereby squeezing or pulling the handlebar 8, causing the handlebar 8 to deflect. At this time, the Hall effect sensor in the first connecting block 7 transmits the angle change information of the handlebar 8 to the display screen 4 to prompt the patient to correct the cycling posture and improve the accuracy of heart rate testing.

[0043] After the patient's rehabilitation training is completed, the pulse oximeter 9 is removed from the hand. The staff pulls the plugging block 201 outwards away from the fixed rod 101, so that the convex part 20101 of the plugging block 201 is separated from between the mounting ring 202 and the handle 8. Then, the pulse oximeter 9 is placed inside the handle 8. It should be noted that the side with the wiring 9001 of the pulse oximeter 9 needs to be placed downward. Then, the plugging block 201 is pressed back into the handle 8. At the same time, the connecting part 20102 on the plugging block 201 will slide upwards under the extrusion of the wiring 9001, thus preventing the plugging block 201 from squeezing the wiring 9001 and causing damage. Storing the pulse oximeter 9 inside the handle 8 can effectively prevent the pulse oximeter 9 from being accidentally collided and squeezed by the staff or patients when hanging on the handrail 5, thus avoiding damage to the instrument. At the same time, storing the pulse oximeter 9 inside the handle 8 does not require the staff to take it out of the storage box and place it again, which is convenient for the staff to quickly test the next patient.

[0044] The torque sensor 11 senses the torque magnitude to monitor the output load (T) of the resistance source 2 in real time. The rotation speed of the foot pedal 10 is monitored in real time by a tachometer. These data are converted into electrical signals and transmitted to the data analysis module 3. The built-in power supply of the data analysis module 3 supplies power to the electromagnet inside the resistance source 2 to generate a magnetic field to form an electromagnetic resistance. The resistance magnitude can be changed by adjusting the current intensity, and then the training load magnitude of the patient can be adjusted. The data analysis module 3 samples and records the output power (P) when the foot pedal 10 rotates. According to the formula (P = n×T), by setting a constant output power (P), the training load (T) can be adjusted in real time according to the patient's training state; when the patient pedals the foot pedal 10 faster, that is, the rotation speed (n) increases, the data analysis module 3 adaptively reduces the current intensity output to the resistance source 2, weakens the magnetic field, and reduces the electromagnetic resistance to reduce the training load (T) of the patient; when the patient pedals the foot pedal 10 slower, that is, the rotation speed (n) decreases, the data analysis module 3 adaptively increases the current intensity output to the resistance source 2, strengthens the magnetic field, and increases the electromagnetic resistance to increase the training load (T) of the patient.

[0045] When the rotation speed (n) of the patient's foot pedal 10 increases, it means that they can move at a faster speed. If the training load (T) is not reduced at this time, it may cause the patient to consume energy too quickly, even exceeding their physical limit, resulting in the risk of excessive fatigue or injury. Therefore, when the rotation speed increases, appropriately reducing the training load can maintain a constant power output and ensure the safety and effectiveness of training. On the contrary, when the rotation speed (n) of the patient's foot pedal 10 slows down, it indicates that their physical strength may be declining or they are in a recovery stage. If the training load (T) is not increased accordingly, the output power (P) may become too low to achieve the expected training effect. That is, by increasing the training load when the rotation speed decreases, the output power can be maintained at an ideal level, neither making the patient feel too relaxed to achieve the exercise purpose nor causing excessive physical burden due to excessive load. In short, by dynamically adjusting the training load in this way, it can be ensured that no matter what physical state the patient is in, they can obtain an appropriate training intensity, which helps to improve the training efficiency and safety, and at the same time can better monitor and evaluate the patient's rehabilitation progress.

[0046] Embodiment 2

[0047] Based on Embodiment 1, as Figure 1 、 Figure 2 and Figures 6 - 8 shown, it further includes a second connecting block 301 and a cleaning block 302; the second connecting block 301 is slidably connected to the plugging block 201 through two round rods; the second connecting block 301 is connected to a cleaning block 302 on one side close to the connecting ball 103, and the cleaning block 302 is made of a soft water-absorbing material.

[0048] The cleaning block 302 and the second connecting block 301 are set to be detachably connected.

[0049] It further includes a positioning frame 303; the positioning frame 303 is fixedly connected inside the grip 8 on the left side.

[0050] It further includes a mounting block 401, a connecting rod 402 and a limiting frame 403; a mounting block 401 is fixedly connected to each mounting ring 202; a connecting rod 402 is rotatably connected between adjacent mounting blocks 401; a limiting frame 403 is slidably connected to the connecting rod 402, and the limiting frame 403 and the connecting rod 402 are in a damped rotational connection.

[0051] A damped rotational connection is provided between each mounting ring 202 and the adjacent grip 8.

[0052] The working principle of this embodiment is:

[0053] After the patient's rehabilitation training, to reduce the risk of cross-infection, it is usually necessary to clean the used pulse oximeter 9. After placing the pulse oximeter 9 inside the grip 8, a sufficient amount of disinfectant is sprayed onto the cleaning block 302, and the cleaning block 302 adsorbs the disinfectant, as Figure 8 shown. Then, after inserting the blocking block 201 back into the grip 8, the second connecting block 301 is repeatedly pulled back and forth, driving the cleaning block 302 containing the disinfectant to slide back and forth at the finger sleeve part of the pulse oximeter 9, thereby cleaning the finger sleeve part of the pulse oximeter 9. The pulse oximeter 9 is limited by the positioning frame 303 to prevent the pulse oximeter 9 from shifting during the cleaning process of the cleaning block 302, which may affect the cleaning effect of the cleaning block 302. After the cleaning is completed, the second connecting block 301 is manually pulled forward to move the cleaning block 302 away from the finger sleeve part of the pulse oximeter 9. Then, an external pump is started to accelerate the air flow inside the grip 8, improving the air-drying efficiency of the cleaned part of the pulse oximeter 9 until the pulse oximeter 9 is completely air-dried. After the cleaning block 302 is used multiple times, the degree of contamination on its surface increases until it does not meet the cleaning use standard. The staff removes it from the second connecting block 301 and reinstalls a new cleaning block 302 to avoid the repeated use of the contaminated cleaning block 302, thereby reducing the risk of cross-infection.

[0054] During the patient's long-term exercise, due to fatigue, the grasping force of the hand gradually decreases, and the fingers will unconsciously approach each other, resulting in adjacent fingers squeezing the pulse oximeter 9, causing the pulse oximeter 9 to shift and affecting the accuracy of the test data. To solve the above situation, before cycling, the finger with the pulse oximeter 9 and the pulse oximeter 9 are inserted together into the limiting frame 403, directly limiting both the pulse oximeter 9 and the patient's finger, and blocking the squeezing of the adjacent fingers on the pulse oximeter 9, thereby preventing the pulse oximeter 9 from shifting and affecting the accuracy of the test data. At the same time, since each mounting ring 202 and the adjacent grip 8 are set to be connected in a damped rotation manner, with the front-to-back view as the reference, the staff can rotate the mounting ring 202 upward or downward according to the length of the patient's finger to adjust the placement height of the limiting frame 403. At the same time, according to the finger being tested by the patient, the limiting frame 403 can be pushed to change the position of the limiting frame 403 on the connecting rod 402, and the limiting frame 403 can be rotated to adjust the inclination angle of the limiting frame 403 to adapt to the patient's hand and improve the patient's comfort.
