Detailed implementation manners

[0031] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0032] As Figures 1 to 6 shown, the lower limb control disorder patient riding assistance device described in the embodiment of the present invention includes a limb movement module, a pelvis fixation module and a power bicycle 1, and the limb movement module and the pelvis fixation module are arranged on the power bicycle 1; the limb movement module includes a first movable joint 2, a second movable joint 3, a third movable joint 4, a first telescopic rod 5 and a second telescopic rod 6, and the first telescopic rod 5 and the second telescopic rod 6 are rotationally connected through the first movable joint 2; the two sides of the power bicycle 1 are connected with pedals 9 through cranks and axles, the side wall of the pedal 9 is installed with a connecting rod 17 through screws, the connecting rod 17 is rotationally connected with the second telescopic rod 6 through the third movable joint 4, a connecting mechanism connected with the pelvis fixation module is arranged on the first movable joint 2, and limiters are arranged on both the second movable joint 3 and the third movable joint 4; a pair of first straps 7 are fixedly connected to the side walls of the first telescopic rod 5 and the second telescopic rod 6, the two sides of one end of the first strap 7 are the male surfaces of the magic tape, the two sides of the other end are the female surfaces of the magic tape, and a second strap 8 is arranged on the pedal 9;

[0033] The starting point of the limb movement module is the first movable joint 2. This first movable joint 2 is connected to the pelvis fixing module through a connecting mechanism and is connected to the second movable joint 3 through a first telescopic rod 5. This first telescopic rod 5 corresponds to the femur of the user. The second movable joint 3 can align with the center of the user's knee joint by adjusting the first telescopic rod 5 and is connected to the third movable joint 4 through a second telescopic rod 6.

[0034] The second movable joint 3 has a limiter in the extension direction, and the extension direction cannot exceed 180° to protect the user's knee joint. The second telescopic rod 6 corresponds to the tibia of the user, and the third movable joint 4 can be made to match the center of the ankle joint by adjusting the second telescopic rod 6.

[0035] The third movable joint 4 is connected to the pedal 9 on the sole of the foot through a short connecting rod 17. The third movable joint 4 has an adjustable limiter to adapt to the range of motion of the user's ankle joint and play a role in protecting the ankle joint. Both the inner and outer sides of the first strap 7 are provided with sponge cushions, and the inner side of the second strap 8 is provided with a sponge cushion. The lower limb is fixed to the first telescopic rod 5 and the second telescopic rod through the first strap 7, and the foot is fixed to the pedal 9 through the second strap 8. Before use, measure the distances between the user's hip joint, knee joint and ankle joint, as well as the distance from the center of the ankle joint to the sole of the foot, and record them. Then, according to the recorded data, adjust the lengths of the first telescopic rod 5 and the second telescopic rod 6 in the limb movement module so that the first movable joint 2, the second movable joint 3 and the third movable joint 4 are respectively aligned with the centers of the hip joint, knee joint, ankle joint and the sole of the foot.

[0036] After the alignment is completed, assist the user to mount the stationary bike 1. First, fix the pelvis fixing module to the user's pelvis, and connect the limb movement module to the pelvis fixing module through the connecting mechanism. Then, install the connecting rod 17 to the pedal 9 with screws and fix it to the lower limb of the patient through the first strap 7 and the second strap 8.

[0037] The pelvis fixing module includes a connecting plate 10 fixedly connected to the stationary bike 1. A hollow rectangular plate 11 is slidably connected to the surface of the connecting plate 10. A group of round holes 12 are opened on the side of the connecting plate 10 away from the stationary bike 1. A threaded rod 14 is threadedly connected to the side of the rectangular plate 11 close to the round holes 12. The threaded rod 14 can be inserted into the round holes 12. Clamping plates 13 are arranged on both sides of the rectangular plate 11;

[0038] Before the patient sits on the stationary bike 1, first rotate the threaded rod 14 to disengage the threaded rod 14 from the round hole 12. Then, the rectangular plate 11 can be moved up and down to move the rectangular plate 11 to a suitable position. Then, reverse-rotate the threaded rod 14 to insert the threaded rod 14 into the corresponding round hole 12, thereby adjusting the height of the pelvic fixation module to match patients of different heights. After that, assist the patient to sit on the stationary bike 1. At this time, through the limb movement module connected to the lower limbs, the movement trajectory of the lower limbs controlled by the correction of its connection with the pedal 9 on the sole and the pelvic fixation module will be adjusted.

[0039] Both sides of the above-mentioned structure are provided with sliding grooves 16, and the clamping plate 13 is slidably connected to the inner wall of the sliding groove 16. A first spring 15 is fixedly connected between the side of the clamping plate 13 close to the threaded rod 14 and the inner wall of the sliding groove 16. Fixed plates 22 are fixedly connected to both sides of the rectangular plate 11. A set of positioning grooves 18 are opened on the bottom surface of the clamping plate 13. A clamping rod 19 that can be inserted into the positioning groove 18 is vertically slidably connected to the fixed plate 22. A circular ring 20 is fixedly connected to the surface of the clamping rod 19. A second spring 21 is fixedly connected between the top surface of the circular ring 20 and the fixed plate 22. Since the body shapes of different patients are different, in order to improve the comfort of using the pelvic fixation module, the clamping rod 19 can be pulled downward so that the clamping rod 19 slides out of the positioning groove 18. Then, the clamping plate 13 can be moved. After the clamping plate 13 is moved to a suitable position, release the clamping rod 19 so that the clamping rod 19 slides into the corresponding positioning groove 18 under the drive of the second spring 21. At this time, the clamping plate 13 will be limited to adjust the position of the clamping plate 13, so as to match patients of different body shapes.

[0040] The connecting mechanism includes a cylinder 24 fixed to the side of the fixed plate 22 away from the rectangular plate 11. The cylinder 24 is arranged at a position close to the hip joint. A fixed rod 23 corresponding to the fixed rod 23 is arranged at the first movable joint 2. A circular groove 25 is opened on the side of the cylinder 24 away from the fixed plate 22. The fixed rod 23 can be inserted into the circular groove 25. In this application, by inserting the fixed rod 23 into the circular groove 25 and then installing the connecting rod 17 on the pedal 9, the installation of the limb movement module can be completed. Since the hemiplegia of the patient's lower limbs may be on the left side or the right side, this application can adaptively install the limb movement module on the side with poor lower limb control. Only the pedal 9 on the sole is reserved on the other side of the stationary bike 1, which is fixed to the ankle and foot and connected to the central axis of the stationary bike 1.

[0041] A set of clamping grooves 28 are formed in the inner wall of the circular groove 25. A set of moving grooves 26 corresponding to the clamping grooves 28 are formed in the side wall of the fixing rod 23. A clamping block 27 clamped with the clamping groove 28 is slidably connected in the moving groove 26. A third spring is fixedly connected between the side of the clamping block 27 away from the clamping groove 28 and the inner wall of the moving groove 26. A separating assembly for separating the clamping block 27 from the clamping groove 28 is arranged on the cylinder 24. Before the fixing rod 23 enters the circular groove 25 in this application, the clamping block 27 is pushed into the moving groove 26, and then the fixing rod 23 is inserted into the circular groove 25. When the clamping groove 28 corresponds to the moving groove 26, the third spring will push the clamping block 27 into the clamping groove 28, so that the clamping block 27 is clamped with the clamping groove 28, thereby firmly connecting the fixing rod 23 and the cylinder 24 and improving the connection stability between the limb movement module and the pelvis fixing module.

[0042] A hollow elastic block 29 is fixedly connected to the side wall of the cylinder 24. A push rod 30 is fixedly connected to the inner wall of the elastic block 29. The push rod 30 is slidably connected to the side wall of the cylinder 24 and extends into the clamping groove 28. When it is necessary to separate the limb movement module and the pelvis fixing module in this application, the outside of the elastic block 29 can be pressed, so that the push rod 30 can push the clamping block 27 out of the clamping groove 28. At this time, the fixing rod 23 can be taken out of the circular groove 25, thereby separating the limb movement module and the pelvis fixing module.

[0043] A riding assistance monitoring system for patients with poor lower limb control, which is applicable to the above-mentioned riding assistance device for patients with poor lower limb control, includes a pressure detection module, a motion monitoring module, an information processing module, a load control module, an information transmission and reception module, and a main control module. The main control module includes a display module and an operation module.

[0044] A riding assistance monitoring system for patients with poor lower limb control, which is applicable to the above-mentioned riding assistance device for patients with poor lower limb control. Pressure detection module: Pressure sensors d are provided at the bottom of the pedal 9 and the top of the inner wall of the strap. The pressure data of the sole and instep during riding are transmitted to the information processing module in real time in a wireless transmission manner for further analysis.

[0045] Motion monitoring module: A position sensor and a speed sensor f are installed in the crank and the bottom bracket connected to the pedal 9, which can sense the movement direction of the pedal 9 and transmit the real-time motion information to the information processing module in a wireless transmission manner for further analysis.

[0046] Information processing module: It is used for real-time analysis of data and formation and output of visual images. After the information from the pressure detection module and the motion monitoring module is transmitted to the information processing module, further analysis will be carried out as follows: When one side of the pedal 9 moves downward, the data of its plantar pressure sensor is collected. After both sides of the pedal 9 complete a downward movement, the pressure data on both sides are compared, and the relative percentage is transmitted to the display module in the form of an image. In addition, the information processing module also has a storage function, which can store patient files and kinematic data during cycling;

[0047] Main control module: The main control module includes a display module and an operation module. The display module is a display screen located above the handle of the exercise bike 1. It can establish and select patient files, query historical information, adjust manual mode and external control mode, and provide the participation status of both lower limbs analyzed by the information processing module to users and medical staff in the form of visual images;

[0048] Information transmission and reception module: The exercise bike 1 is equipped with signal input and output ports, which can obtain and send external information through wired connection, and automatically adjust the load according to the instruction requirements of the connected computer;

[0049] The operation module includes a highly sensitive touch screen. The operator can operate through the touch screen to retrieve and store user files and historical training records, adjust the manual mode and external control mode, and adjust the load of the exercise bike 1;

[0051] When the user uses this exercise bike to exercise through an external computer or the like, first switch to the external control mode through the display screen of the main control module, and connect the exercise bike 1 to an external control system such as an external computer through a data connection cable, and dynamically adjust the resistance of the exercise bike 1 in a timely manner according to the control of the external system. When the user uses the manual mode, the user can create a patient file and adjust the resistance through the display screen of the main control module. In addition, regardless of which control mode, when the user starts cycling on the exercise bike 1, the screen will display the force comparison generated by both lower limbs during cycling through the information provided by the pressure sensors on both sides, collect the user's exercise data through pressure sensors, and display the corresponding data to the user and medical staff through intelligent analysis and visualization processing, and guide the user to change to a normal and symmetrical exercise mode through biofeedback, further improving the user's exercise ability.

[0052] Such as Figure 7As shown, a method for using a cycling assistance device and an assistance monitoring system for patients with poor lower limb control. This method is used for the above-mentioned cycling assistance monitoring system for patients with poor lower limb control, and the method includes the following steps:

[0053] S1: Measure the distances between the user's hip joint, knee joint and ankle joint, and the distance from the center of the ankle joint to the sole of the foot, and record them. Then, according to the recorded data;

[0054] S2: According to the recorded data, adjust the lengths of the first telescopic rod 5 and the second telescopic rod 6 so that the first movable joint 2, the second movable joint and the third movable joint 4 are respectively aligned with the centers of the hip joint, knee joint, ankle joint and the sole of the foot;

[0055] S3: Assist the user to mount the exercise bike 1. First, fix the pelvic fixation module to the user's pelvis, and connect the limb movement module to the pelvic fixation module by means of the connection mechanism;

[0056] S4: Switch to the external control mode through the display screen of the main control module, and connect the exercise bike 1 to an external control system such as an external computer through a data connection line, and dynamically adjust the resistance of the exercise bike 1 in a timely manner according to the control of the external system;

[0057] S5: When the user uses the manual mode, the user can create a patient file and adjust the resistance through the display screen of the main control module;

[0058] S6: When the user starts cycling on the exercise bike 1, the screen will display the force comparison generated by both lower limbs during cycling through the information provided by the pressure sensors on both sides, and collect the patient's motion data through the pressure sensors.

[0059] Working principle: By measuring the distances between the user's hip joint, knee joint and ankle joint, as well as the distance from the center of the ankle joint to the sole of the foot, and recording them, then according to the recorded data, adjust the lengths of the first telescopic rod 5 and the second telescopic rod 6 in the limb movement module, so that the first movable joint 2, the second movable joint and the third movable joint 4 are respectively aligned with the centers of the hip joint, knee joint, ankle joint and the sole of the foot. After the alignment is completed, assist the user to get on the stationary bike 1. First, fix the pelvis fixing module to the user's pelvis, and connect the limb movement module to the pelvis fixing module by means of a connecting mechanism. Then, install the connecting rod 17 on the pedal 9 with screws and fix it to the patient's lower limb through the first strap 7 and the second strap 8; before the patient sits on the stationary bike 1, first rotate the threaded rod 14 to make the threaded rod 14 disengage from the round hole 12, then the rectangular plate 11 can be moved up and down, move the rectangular plate 11 to a suitable position, and then reverse the threaded rod 14 to make the threaded rod 14 insert into the corresponding round hole 12, so as to adjust the height of the pelvis fixing module to match patients of different heights. After that, assist the patient to sit on the stationary bike 1. At this time, through the limb movement module connected to the lower limb, the movement trajectory of the lower limb controlled by the connection correction between the pedal 9 of the sole of the foot and the pelvis fixing module will be adjusted;

[0060] Since the body shapes of different patients are different, in order to improve the comfort of using the pelvis fixing module, the lever 19 can be pulled downwards so that the lever 19 slides out of the positioning groove 18, and then the clamping plate 13 can be moved. After the clamping plate 13 is moved to a suitable position, release the lever 19 so that the lever 19 slides into the corresponding positioning groove 18 under the drive of the second spring 21. At this time, the clamping plate 13 will be limited to adjust the position of the clamping plate 13 to match patients of different body shapes; In this application, by inserting the fixing rod 23 into the round groove 25 and then installing the connecting rod 17 on the pedal 9, the installation of the limb movement module can be completed. Since the hemiplegia of the patient's lower limb may be on the left or on the right, this application can adaptively install the limb movement module on the side with poor lower limb control. Only the pedal 9 of the sole of the foot is reserved on the other side of the stationary bike 1, which is fixed to the ankle and foot and connected to the central axis of the stationary bike 1;

[0061] Before the fixed rod 23 enters the circular groove 25, the push block 27 is pushed into the moving groove 26, and then the fixed rod 23 is inserted into the circular groove 25. When the card slot 28 corresponds to the moving groove 26, the third spring will push the push block 27 into the card slot 28, so that the push block 27 is clamped with the card slot 28, thereby firmly connecting the fixed rod 23 and the cylinder 24, and improving the connection stability between the limb movement module and the pelvis fixing module. When the limb movement module and the pelvis fixing module need to be separated in this application, the outside of the elastic block 29 can be pressed, so that the push rod 30 can push the push block 27 out of the card slot 28. At this time, the fixed rod 23 can be taken out of the circular groove 25, so that the limb movement module and the pelvis fixing module are separated.
