Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1 to 8 , the present invention provides a technical solution: a 5G intelligent medical device for rapid postoperative rehabilitation of children, including a U-shaped base 1 and a 5G module 2 arranged thereon, and a rocker arm mechanism for exercising the shoulders and arms of children is arranged on the U-shaped base 1;

[0036] The rocker arm mechanism includes a horizontal shaft 3 rotatably fixed on the U-shaped base 1. Both ends of the horizontal shaft 3 are rotatably fixed on the U-shaped base 1. The U-shaped base 1 is further provided with an arm rod 16 that rotates freely by manual pushing in the vertical direction, and a same-position component that drives the horizontal shaft 3 to rotate synchronously when the arm rod 16 rotates;

[0037] A handle rod 19 for a child to hold is arranged on the arm rod 16, and a centering component for dynamically adjusting the distance between the handle rod 19 and the rotation center point of the arm rod 16 when the arm rod 16 rotates is arranged on the arm rod 16;

[0038] The U-shaped base 1 is fixedly connected to a mounting frame 5, on which a spline shaft 6 that rotates synchronously with the transverse shaft 3 is provided, and a photoelectric meter 11 that detects the number of rotations of the spline shaft 6 is fixedly connected to the mounting frame 5. The photoelectric meter 11 is electrically connected to the 5G module 2, and the mounting frame 5 is provided with a speed change component for adjusting the rotational meshing ratio between the transverse shaft 3 and the spline shaft 6.

[0039] like Figure 1 , Figure 2 and Figure 8 As shown, when training children's arms, an active training method is adopted. When using, the children hold the handle 19 with their hands and use the strength of their own arms to push the handle 19 to drive the arm 16 to rotate in the vertical direction.

[0040] Among them, driven by the isotropic component, the transverse shaft 3 and the arm 16 rotate synchronously, and a spline shaft 6 that rotates synchronously with the spline shaft 6 is provided on one side of the spline shaft 6, and a photoelectric meter 11 for measuring the number of rotations of the spline shaft 6 is provided on the mounting frame 5, and then by measuring the number of rotations of the photoelectric meter 11 per unit time, the recovery of the child's arm can be determined.

[0041] Among them, the photoelectric meter 11 can output a pulse signal or a digital signal at a high frequency, and the signal output by the photoelectric meter 11 is converted into a digital format suitable for transmission through a microcontroller. For example, the microcontroller reads the pulse signal, converts it into a digital signal, calculates the number of rotations per unit time, and encapsulates the number of rotations data into a format suitable for transmission.

[0042] At the same time, the microcontroller is connected to the 5G module 2 through the serial port or SPI interface. The 5G module 2 is responsible for transmitting the encapsulated data to the cloud platform through the 5G network. Among them, the 5G module 2 uses a low-latency transmission protocol to ensure the efficiency and real-time performance of data transmission. During the transmission process, the data is encrypted through an encryption protocol to ensure the security of the data.

[0043] The cloud platform receives the data transmitted by 5G module 2 and stores it in the database. The data is stored in a structured format in the cloud database to facilitate subsequent analysis and query. At the same time, the data is backed up regularly to ensure the integrity and reliability of the data. The cloud platform analyzes the stored data in real time and generates a rehabilitation training report. The analysis content includes:

[0044] Rotation circle statistics: calculate the number of rotation circles per unit time to evaluate the intensity of rehabilitation training.

[0045] Trend analysis: Analyze children’s training status in different time periods and evaluate rehabilitation progress.

[0046] Anomaly detection: Detect anomalies in the training data, such as a sudden decrease or increase in the number of rotation cycles.

[0047] And according to the preset rehabilitation plan, when the training data reaches the set threshold, it can automatically send a reminder to medical staff. For example, when the number of rotation cycles is lower or higher than the set value, it reminds the medical staff to adjust the rehabilitation plan. The medical staff receives the analysis results of the cloud platform through the terminal device. Furthermore, the medical staff can view the rehabilitation training data of the child in real time, including the number of rotation cycles, training time, rehabilitation progress, etc. Then, they can remotely adjust the parameters of the rehabilitation device according to the real-time data.

[0048] When adjusting the parameters of the rehabilitation device, an instruction is sent through the 5G module 2 and the rotational engagement ratio between the transverse shaft 3 and the spline shaft 6 is adjusted through the speed change component. Among them, the transverse shaft 3 rotates synchronously with the arm rod 16. Then, when the arm rod 16 rotates one week, due to the different rotational engagement ratios of the transverse shaft 3 and the spline shaft 6, when the arm rod 16 rotates a fixed number of cycles, the number of rotation cycles of the spline shaft 6 is different. Therefore, if the spline shaft 6 is to reach the set number of cycles per unit time, the arm rod 16 needs to rotate more cycles to complete the training goal of this intensity. And when the training goal is completed, the rotational engagement ratio between the transverse shaft 3 and the spline shaft 6 is further changed through the speed change component, so as to carry out the next stage of rehabilitation training.

[0049] At the same time, the child holds the handle rod 19 during the training process to drive the arm rod 16 to rotate. During the rotation of the arm rod 16, the distance between the handle rod 19 and the rotation center point of the arm rod 16 can be changed at all times, so that the swing amplitude of the arm changes during each rotation. This reciprocating change in distance allows the child's arm to experience different amplitudes of swing in one training, thereby simulating various movement patterns of the arm in daily life, helping the child better adapt to different movement scenarios, and through different amplitudes of swing, exercising more muscle groups and joints, promoting the all-round development of muscles.

[0050] It should be noted that in the actual use process, an optical-electronic counter 11 with a rotary shaft output can be selected, and the output shaft of the optical-electronic counter 11 is coaxially fixed with the spline shaft 6. Then, when the spline shaft 6 rotates, the output shaft of the optical-electronic counter 11 will also rotate synchronously. Then, the sensor inside the optical-electronic counter 11 can detect the rotation of the output shaft and output the number of rotation cycles through a pulse signal.

[0051] In a relatively preferred embodiment, the co-location component includes an axis plate 12 fixedly connected to the end of the arm rod 16. A hollow column 15 is coaxially fixed to one side of the axis plate 12 facing the U-shaped base 1, and the hollow column 15 rotates axially on the U-shaped base 1;

[0052] A driving position gear 14 is fixedly sleeved on the hollow column 15. The driving position gear 14 is meshed and connected with a driven gear 13. The driven gear 13 rotates on the U-shaped base 1 around a fixed axis and is coaxially fixed with the transverse shaft 3.

[0053] As Figure 1 and Figure 6 shown, when the arm rod 16 rotates, it can drive the central axis plate 12 fixedly arranged at its end to rotate synchronously. The central axis plate 12 rotates on the U-shaped base 1 around a fixed axis through the hollow column 15 fixedly arranged on it. Therefore, when the arm rod 16 rotates, it can drive the hollow column 15 and the driving position gear 14 fixedly sleeved on it to rotate synchronously.

[0054] Meanwhile, the driving position gear 14 is meshed and connected with the driven gear 13, and the driven gear 13 is coaxially arranged with the transverse shaft 3. Therefore, when the arm rod 16 rotates, it can drive the transverse shaft 3 to rotate synchronously, and then through a speed change assembly, the rotation speed of the spline shaft 6 can be changed on the premise that the rotation speeds of the arm rod 16 and the transverse shaft 3 remain unchanged, so as to set different rotation indexes in the rehabilitation training process at different stages.

[0055] Based on the embodiment of the same-position assembly, the speed change assembly includes a guiding friction roller 7 slidably sleeved on the spline shaft 6. A conical cylinder 4 is fixedly sleeved on the transverse shaft 3. The conical cylinder 4 includes an integrally formed outwardly inclined conical surface 401, and the outer peripheral surfaces of the outwardly inclined conical surface 401 and the guiding friction roller 7 are in frictional contact with each other;

[0056] Both ends of the spline shaft 6 rotate on the mounting bracket 5 around a fixed axis. The mounting bracket 5 is provided with a positioning clamp seat 8 for driving the guiding friction roller 7 to move freely along the laying direction of the spline shaft 6. The positioning clamp seat 8 is provided with a limiting clamp groove 9 for accommodating the guiding friction roller 7. The outer side surface of the guiding friction roller 7 is in sliding contact with the inner wall of the limiting clamp groove 9. The spline shaft 6 and the outwardly inclined conical surface 401 are parallel to each other in the vertical section.

[0057] The mounting bracket 5 is provided with a threaded rod 10 that rotates freely driven by a motor. Both ends of the threaded rod 10 rotate on the mounting bracket 5 around a fixed axis, and the threaded rod 10 and the spline shaft 6 are parallel to each other. The threaded rod 10 is in threaded cooperation with the positioning clamp seat 8. The mounting bracket 5 is provided with a rectangular groove for the positioning clamp seat 8 to slide and connect;

[0058] In the initial state, the perimeter difference between the guiding friction roller 7 and the corresponding position of the outwardly inclined conical surface 401 is the largest.

[0059] As Figures 1 - 5As shown, when the transverse shaft 3 rotates driven by the arm rod 16, it can drive the conical cylinder 4 fixedly arranged thereon to rotate synchronously. Among them, during the rotation of the conical cylinder 4, the integrally formed inclined outer conical surface 401 thereon is in frictional contact with the outer peripheral surface of the guiding friction roller 7. Thus, when the conical cylinder 4 rotates, it can drive the guiding friction roller 7 and the spline shaft 6 to rotate.

[0060] Meanwhile, when changing the rotation engagement ratio between the transverse shaft 3 and the spline shaft 6, the motor fixedly arranged on the mounting bracket 5 drives the threaded rod 10 to freely rotate, and then drives the positioning clamp seat 8 threadedly connected to the threaded rod 10 to move. Among them, the guiding friction roller 7 is located in the limiting clamping groove 9 opened on the positioning clamp seat 8. Thus, when the positioning clamp seat 8 moves, it can drive the guiding friction roller 7 to slide on the spline shaft 6 through the limiting clamping groove 9 opened thereon, thereby changing the relative position between the guiding friction roller 7 and the conical cylinder 4.

[0061] At the same time, in the initial state, the perimeter difference between the corresponding positions of the guiding friction roller 7 and the inclined outer conical surface 401 is the largest. Thus, when the transverse shaft 3 and the arm rod 16 rotate a certain number of turns, it can drive the spline shaft 6 to rotate more turns. Subsequently, the perimeter difference between the guiding friction roller 7 and the inclined outer conical surface 401 is changed by the rotation of the threaded rod 10, so that when the arm rod 16 and the transverse shaft 3 rotate a fixed number of turns, the actual number of turns of the spline shaft 6 can be reduced. Thus, when it is necessary to reach the set rehabilitation training index, it is necessary to drive the arm rod 16 to rotate more turns per unit time.

[0062] On the basis of the embodiment of the speed change assembly, the centering assembly includes an axial sliding groove 20 opened on the arm rod 16. A reciprocating lead screw 17 that rotates freely is arranged in the axial sliding groove 20, and both ends of the reciprocating lead screw 17 are rotationally fixed on the arm rod 16;

[0063] An axial block 18 is slidably connected to the axial sliding groove 20. The axial block 18 is in threaded cooperation with the reciprocating lead screw 17, and the axial block 18 and the handle rod 19 are fixedly connected to each other.

[0064] One end of the reciprocating lead screw 17 facing the axial center plate 12 is coaxially fixed with a driving bevel gear 21, and the driving bevel gear 21 is meshed with a driven bevel gear 22. One end of the driven bevel gear 22 facing the U-shaped base 1 is coaxially fixed with a concentric shaft 23. The concentric shaft 23 is located inside the hollow column 15 and is fixedly connected to the U-shaped base 1.

[0065] As Figure 1 and Figure 6As shown, when the arm 16 rotates freely with the position of the hollow column 15 as the rotation center, it can drive the reciprocating screw rod 17 that rotates on a fixed axis thereon to rotate synchronously. Among them, a driving bevel gear 21 is coaxially fixed at the end of the reciprocating screw rod 17, and the driving bevel gear 21 is meshed and connected with a driven bevel gear 22, and the driven bevel gear 22 is fixedly arranged on the U-shaped base 1 through a concentric shaft 23. Therefore, when the driving bevel gear 21 and the reciprocating screw rod 17 rotate with the driven bevel gear 22 and the hollow column 15 as the center, it can drive the driving bevel gear 21 and the reciprocating screw rod 17 to rotate on the arm 16.

[0066] Meanwhile, when the reciprocating screw rod 17 rotates, it can change the horizontal position of the axial block 18 that is in threaded fit with it, and the axial block 18 is fixedly connected to the handle rod 19, so that it can drive the handle rod 19 to slide on the arm 16, that is, change the distance between the handle rod 19 and the rotation center point of the arm 16.

[0067] At the same time, when the arm 16 continues to rotate, it can drive the handle rod 19 to reciprocate on the arm 16, and then repeatedly change the distance between the handle rod 19 and the rotation center point of the arm 16. The change in the position of the handle rod 19 will change the swing amplitude of the arm during rotation, and thus children's arms can experience swings of different amplitudes in one training to more closely simulate various movement patterns of the arms in daily life and help children better adapt to different movement scenarios.

[0068] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
