[0002] A rehabilitation bicycle is a piece of fitness equipment specially designed to evaluate and improve the user's cardiopulmonary function. Currently, most rehabilitation bicycles can adjust the height of the seat and armrests according to patients of different heights. When patients are undergoing rehabilitation training, they need to put their hands on the armrests to maintain body balance. Different patients have different shoulder widths. When the width of the armrests matches the patient's shoulder width, the patient can better maintain body balance and reduce shaking and instability. However, existing rehabilitation bicycles cannot be adapted to the shoulder width of different patients. Not only will patients feel uncomfortable during use, but there is also a risk of patients falling.

[0003] At the same time, patients usually feel gradually weak after exercising for a period of time, and their bodies will unconsciously lean forward or backward after fatigue, which will affect the riding posture, cause muscle tension in other parts, increase the workload of the heart, and affect the accuracy of the heart rate test data. Summary of the invention

[0004] In order to overcome the shortcomings that existing rehabilitation bicycles cannot be adjusted according to the shoulder width of different patients, which not only makes patients feel uncomfortable during use, but also poses a risk of patients falling. At the same time, after the patient becomes weak, the body will unconsciously lean forward or backward, thereby affecting the riding posture and reducing the accuracy of the heart rate test data, the present invention provides a rehabilitation training device based on cardiopulmonary testing.

[0007] Furthermore, each grip is configured as a hollow structure; each grip is provided with a plurality of flow grooves that help to dissipate heat from the patient's hands; each connecting ball is provided with a through hole, and each through hole and the flow groove are in a connected state.

[0008] Furthermore, each flow slot of the handle is provided with a rubber ring for enhancing the ventilation effect.

[0009] Furthermore, it also includes a blocking block and a mounting ring; the blocking block is slidably connected to the side of the handle away from the connecting ball; a plurality of mounting rings are connected to the handle; a convex portion is provided on the blocking block, and the convex portion can slide in the groove formed between the mounting ring and the adjacent handle; and a connecting portion is provided on the blocking block.

[0010] Furthermore, it also includes a second connecting block and a cleaning block; the second connecting block is slidably connected to the blocking block through two round rods; the second connecting block is connected to a cleaning block for cleaning the pulse oximeter on the side close to the connecting ball, and the cleaning block is made of soft water-absorbent material.

[0015] The beneficial effects are as follows: the present invention realizes that the first connecting block drives the adjacent handles to move, thereby adjusting the distance between the two handles to adapt to the shoulder widths of different patients and enhance the balance of the patient's movement process. At the same time, the appropriate handle distance can help the patient maintain a correct sitting posture and reduce muscle tension and joint pressure caused by bad posture.

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

[0036] It also includes a blocking block 201 and a mounting ring 202; the blocking block 201 is slidably connected to the side of the handle 8 located at the rear side away from the connecting ball 103; two front-to-back symmetrical mounting rings 202 are connected to the handle 8 located at the rear side; a protrusion 20101 is provided on the blocking block 201, and the protrusion 20101 can slide in the groove formed between the mounting ring 202 and the adjacent handle 8; the blocking block 201 is provided with a connecting portion 20102.

[0037] Existing rehabilitation bicycles cannot be adjusted according to the shoulder width of different patients. Not only will they make patients feel uncomfortable during use, but there is also a risk of patients falling. At the same time, when patients become weak, their bodies will unconsciously lean forward or backward, which will affect the riding posture and reduce the accuracy of heart rate test data.

[0038] The working steps of this embodiment are:

[0039] First, according to the patient's shoulder width, the adjacent first connecting blocks 7 on the fixed block 6 are moved respectively, so that the first connecting blocks 7 drive the adjacent handles 8 to move together. At this time, the folding tube 102 follows the movement of the handle 8 to shrink or stretch until the distance between the two handles 8 matches the patient's shoulder width. Then, the limiting rod 7001 on the first connecting block 7 is pressed downward to insert the limiting rod 7001 into the limiting hole 6001 of the adjacent fixed block 6, thereby fixing the position of the first connecting block 7 and the handle 8; the adjacent handles 8 are driven to move by the first connecting block 7, so as to adjust the distance between the two handles 8 to adapt to the shoulder width of different patients and enhance the balance of the patient's movement process. At the same time, the appropriate distance of the handles 8 can help patients maintain a correct sitting posture and reduce muscle tension and joint pressure caused by bad posture.

[0040] Next, manually pass the connection 9001 of the pulse oximeter 9 through the limit ring 5001 on the armrest 5, and neatly limit the connection 9001 to one side of the armrest 5 to prevent the patient from squeezing the connection 9001 when riding, causing the pulse oximeter 9 to fall off from the patient's fingers, avoiding affecting the patient's test data, and then adjust the armrest 5 and the seat height of the bicycle body 1. Then the patient sits on the seat, clamps the pulse oximeter 9 on one of the fingers, and installs and clamps other test instruments, holds the handle 8 with both hands, and then starts the resistance source 2 according to the patient's physical condition, and adjusts the resistance of the pedal on the bicycle body 1 by changing the magnetic field strength between the internal magnet and the flywheel to adjust the patient's exercise difficulty, starts riding, and records 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 the body. When the patient's hands sweat, the skin surface will become wet, thereby affecting the contact between the pulse oximeter 9 and the skin, making it impossible for the pulse oximeter 9 to be stably attached to the skin, affecting the accuracy of the data. To solve the above problem, after the patient exercises for a period of time, the external pump is started to allow the airflow to pass through the armrest 5 into the adjacent folding tube 102, and then through the through hole 10301 of the connecting ball 103. Finally, the liquid is sprayed toward the patient's hand from the flow groove 8001 of the grip 8, thereby reducing the heat accumulation between the patient's hand and the grip 8, keeping the patient's hand in a relatively cool state, and further improving the clamping stability of the pulse oximeter 9. At the same time, the gap between the patient's hand and the grip 8 is increased by the rubber ring 8002 to promote air circulation, further improving 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 grip 8, thereby improving the stability and comfort of the patient's grip.

[0042] After a long period of exercise, the patient will gradually feel weak, 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 toward the hand or tilt backward as a whole, thereby squeezing or pulling the handle 8, causing the handle 8 to deflect. At this time, the Hall effect sensor in the first connecting block 7 transmits the angle change information of the handle 8 to the display screen 4, prompting the patient to correct the riding posture and improve the accuracy of the heart rate test.

[0043] After the patient's rehabilitation training is completed, the pulse oximeter 9 is taken off from the hand, and the staff pulls out the blocking block 201 to the side away from the fixing rod 101, so that the convex part 20101 of the blocking block 201 is separated from between the mounting ring 202 and the handle 8, and then the pulse oximeter 9 is placed inside the handle 8. It should be noted that the wiring 9001 side of the pulse oximeter 9 needs to be placed downward, and then the blocking block 201 is pressed back into the handle 8. At the same time, the connecting part 20102 on the blocking block 201 The wiring 9001 squeezed by the blocking block 201 will slide upward to prevent the wiring 9001 from being squeezed and damaged. The pulse oximeter 9 will be stored inside the handle 8, which will effectively prevent the pulse oximeter 9 from being hung on the handrail 5 and accidentally hit and squeezed by the staff or patients, thereby avoiding damage to the instrument. At the same time, the pulse oximeter 9 is stored inside the handle 8, and the staff does not need to take it out of the storage box and put it back, which is convenient for the staff to quickly test the next patient.

[0044] The torque sensor 11 senses the torque to monitor the output load (T) of the resistance source 2 in real time, and the tachometer monitors the speed (n) of the pedal 10 in real time. 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 electromagnetic resistance. The resistance can be changed by adjusting the current intensity, thereby adjusting the training load of the patient. The data analysis module 3 samples and records the output power (P) when the pedal 10 rotates. According to the formula (P=n×T), a constant output power (P) is set, and the training load (T) can be adjusted in real time according to the patient's training state. When the patient pedals the pedal 10 at a faster speed, that is, the 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, so as to reduce the patient's training load (T); when the patient pedals the pedal 10 at a slower speed, that is, the 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, so as to increase the patient's training load (T).

[0045] When the rotation speed (n) of the patient's pedaling 10 increases, it means that they can exercise 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 or even exceed their physical limit, causing 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 the training; on the contrary, when the rotation speed (n) of the patient's pedaling 10 slows down, it means 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 and the expected training effect cannot be achieved; that is, by increasing the training load when the rotation speed decreases, the output power can be maintained at an ideal level, which will neither make the patient feel too relaxed and fail to achieve the purpose of exercise, nor cause the body to be overburdened due to excessive load; in short, by dynamically adjusting the training load in this way, it can ensure that no matter what physical state the patient is in, he can obtain appropriate training intensity, which helps to improve training efficiency and safety, and also can better monitor and evaluate the patient's rehabilitation progress.

[0046] Example 2

[0047] On the basis of Example 1, Figure 1 , Figure 2 and Figure 6-Figure 8 As shown, it also includes a second connecting block 301 and a cleaning block 302; the second connecting block 301 is slidably connected to the blocking block 201 through two round rods; the second connecting block 301 is connected to the cleaning block 302 on the side close to the connecting ball 103, and the cleaning block 302 is made of soft water-absorbing material.

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

[0049] It also includes a positioning frame 303; the positioning frame 303 is fixedly connected to the handle 8 on the left side.

[0050] It also includes a mounting block 401, a connecting rod 402 and a limit frame 403; each mounting ring 202 is fixedly connected with a mounting block 401; a connecting rod 402 is rotatably connected between two adjacent mounting blocks 401; the limit frame 403 is slidably connected to the connecting rod 402, and the limit frame 403 and the connecting rod 402 are connected in a damping rotation manner.

[0051] Each mounting ring 202 is arranged to be connected to the adjacent handle 8 in a damped rotational connection.

[0052] The working principle of this embodiment is:

[0053] After the patient's rehabilitation training is completed, in order to reduce the risk of cross infection, it is usually necessary to clean the pulse oximeter 9 after use. After the pulse oximeter 9 is placed inside the grip 8, a sufficient amount of disinfectant is sprayed on the cleaning block 302, and the disinfectant is absorbed by the cleaning block 302. Figure 8 As shown, after the blocking block 201 is inserted back into the handle 8, the second connecting block 301 is repeatedly pulled forward and backward, and the cleaning block 302 containing the disinfectant is driven to slide forward and backward on the finger sleeve of the pulse oximeter 9, so as to clean the finger sleeve 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, thereby affecting the cleaning effect of the cleaning block 302. After the cleaning is completed, the second connecting block 301 is manually pulled forward to make the cleaning block 302 move forward. The cleaning block 302 is moved away from the fingertip portion of the pulse oximeter 9, and then the external pump is started to accelerate the airflow in the grip 8 and improve the air-drying efficiency of the clean portion of the pulse oximeter 9 until the pulse oximeter 9 is completely air-dried. After the cleaning block 302 is used for many times, the degree of contamination on its surface increases until it does not meet the cleaning and use standards. The staff removes it from the second connecting block 301 and reinstalls a new cleaning block 302 to avoid reuse of the contaminated cleaning block 302, thereby reducing the risk of cross infection.

[0054] During long-term exercise, the patient's hand grip strength gradually decreases due to fatigue, and the fingers will unconsciously move closer to each other, causing the adjacent fingers to squeeze the pulse oximeter 9, causing the pulse oximeter 9 to shift, affecting the accuracy of the test data. To solve the above situation, before riding, the patient inserts the finger with the pulse oximeter 9 together with the pulse oximeter 9 into the limit frame 403, directly limits the pulse oximeter 9 and the patient's finger, and blocks the adjacent fingers from squeezing the pulse oximeter 9, thereby preventing the pulse oximeter from shifting. 9 is displaced, affecting the accuracy of the test data. At the same time, since each mounting ring 202 is arranged to be connected to the adjacent grip 8 with a damping rotation, based on the view from the front to the back, 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 limit frame 403. At the same time, according to the patient's tested finger, the staff can push the limit frame 403 to change the position of the limit frame 403 on the connecting rod 402, rotate the limit frame 403, and adjust the inclination angle of the limit frame 403 to adapt to the patient's hand and improve the patient's comfort.
