Description

Technical Field

[0001] The present invention belongs to the technical field of stretching and traction devices, and particularly relates to a traction device for bone injuries in sports. Background Art

[0002] In sports, injuries are a common problem. Especially when bones are damaged, it is usually necessary to use traction and fixation devices to promote recovery. By providing stable support and appropriate traction force, it helps the bones to be correctly aligned, reduces pain, and accelerates the healing process.

[0003] The existing bone injury traction devices have the following deficiencies:

[0004] 1. When a patient feels pain, it is usually necessary to report to the medical staff, and then the medical staff will conduct a pain assessment and decide whether to use invasive pain relief methods such as painkillers. This method has a certain delay, and the patient needs to rely on external medical staff to relieve pain. In addition, frequent invasive operations may bring side effects and infection risks;

[0005] 2. When a patient undergoes lumbar support traction, a lying position is usually required. However, the lumbar support and traction force are affected by the patient's weight. The greater the patient's weight, the greater the traction force required for the lumbar region. The existing traction devices have limitations in the automatic adjustment of lumbar traction force and cannot adjust the traction force according to the patient's weight;

[0006] 3. In the control of limb traction force of traditional traction devices, it often relies on manual intervention or auxiliary tools such as a tensile force measuring device to measure and adjust the traction force. When the traction force reaches a certain value, it is necessary to manually turn off and stop further traction, which not only increases the workload of medical staff but also is prone to misoperation.

[0007] Therefore, there is a need for a traction device for bone injuries in sports that has automated pain management, is suitable for a wide range of people, and has intelligent traction force control to solve the above problems. Summary of the Invention

[0008] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a traction device for sports-related bone injuries. By integrating a TENS electrostimulator and an electromyogram sensor, it realizes automated pain management, reduces the dependence on external medical staff, monitors the patient's pain status in real time, and automatically triggers non-invasive pain relief measures. At the same time, by integrating a telescopic cylinder and a sliding connecting plate, it realizes weight adaptive adjustment, breaks the limitation that traditional traction devices cannot adjust the traction force according to the patient's weight, and improves the accuracy and uniformity of the traction force. In addition, by integrating a multi-stage pneumatic telescopic rod and a baffle, it realizes intelligent control of the traction force of the limbs, automatically stops after reaching a certain traction force, reduces the need for manual intervention, and improves the convenience and accuracy of operation.

[0029] 3. Achieve "automatic appropriate stop of traction" through "intelligent air pressure control": When the air pressure in the installation box rises to a certain value, the traction force reaches the preset appropriate value.

This design ensures the precise control of the traction force. When the appropriate traction force is reached, the device will automatically stop further traction, reducing the need for manual intervention and improving the convenience and accuracy of operation.

After the electromagnet 17 is energized, it is magnetically connected to the iron plate 18.

[0044] The base end of the telescopic cylinder 24 is fixedly connected to the fixing plate 1. The output end of the telescopic cylinder 24 is fixedly provided with a lumbar support 25. One side of the first baffle 19 is fixedly connected with a first sliding connecting plate 37. One side of the second baffle 20 is fixedly connected with a second sliding connecting plate 34. A first tension spring 21 is fixedly arranged on the outer wall of the base end of the telescopic cylinder 24. A second tension spring 22 is fixedly arranged on the inner side wall of the installation box 3. The first sliding connecting plate 37 is fixedly connected with the first tension spring 21. The second sliding connecting plate 34 is fixedly connected with the second tension spring 22. An air pump 4 is fixedly arranged on the outer wall of the bottom of the installation box 3. The air outlet end of the air pump 4 is connected to the inside of the installation box 3 in a through manner.

[0045] The outer wall of the second sliding connecting plate 34 is provided with a frosted layer. The pulling force of the second tension spring 22 is less than the pulling force of the first tension spring 21.

[0046] A TENS electrostimulator 27 and an electromyogram sensor 28 are fixedly arranged on the fixing plate 1. A central processor 29 is fixedly arranged on the fixing plate 1. The central processor 29 is electrically and controllably connected to the TENS electrostimulator 27 and the electromyogram sensor 28.

[0047] A touch switch 7 is fixedly arranged on the top wall of the magnet 8. The touch switch 7 is electrically and controllably connected to the electromagnet 17.

[0048] An ankle fixing bracket 14 is fixedly arranged on the sliding plate 13.

[0049] When the second tension spring 22 resets, the second ventilation hole 23 corresponds to the second ventilation pipe 33; when the first tension spring 21 resets, the first ventilation hole 36 corresponds to the first ventilation pipe 35.

[0050] In specific use, first, the first connecting rod 15 is installed on the connecting plate 12, and then the electromagnet 17 is started to make the electromagnet 17 and the iron plate 18 in an adsorbed state. First, the patient lies flat on the fixing plate 1, and the axillary support 10 provides support for the armpit. Then, the arm fixing bracket 11 is used to fix the arm, and the ankle fixing bracket 14 is used to fix the ankle. At this time, the patient's legs are in a bent state;

[0051] Then, start the air pump 4. The air pump 4 transmits gas into the installation box 3. At this time, since the outer wall of the sliding connecting plate II 34 is a frosted layer, there is frictional resistance between the sliding connecting plate II 34 and the fixed plate 1. Therefore, the gas will first enter the telescopic cylinder 24. The telescopic cylinder 24 drives the lumbar support 25 to move upward, thereby tractionally supporting the patient's waist. When the air pressure in the installation box 3 rises to a certain value, the baffle II 20 will move outward under the tension of the tension spring II 22. At this time, the baffle II 20 will block the telescopic cylinder 24, so that the patient's waist is in a supported state. If the patient is overweight, the baffle II 20 can be manually blocked to prevent it from moving outward, and then the baffle I 19 is pulled to block the multi-stage pneumatic telescopic rod 26, thereby increasing the air pressure inside the telescopic cylinder 24 to achieve the traction support effect on the waist of overweight patients;

[0052] After the telescopic cylinder 24 is blocked, the air pressure in the installation box 3 further increases. At this time, the gas enters the ventilation hole 23 and the ventilation pipe 33, and then enters the multi-stage pneumatic telescopic rod 26. The multi-stage pneumatic telescopic rod 26 drives the sliding plate 13 to move outward, thereby pulling the patient's arm and leg to move. At this time, since the patient's arm is subjected to a pulling force, the upper body of the patient moves, thereby driving the armpit support 10 to move. When the slope wall of the armpit support 10 slides against the slope wall of the inclined block 5, the armpit support 10 drives the inclined block 5, the guide post 6, the magnet 8 and the counterweight iron block 9 to move upward. During this process, the pulling and traction force on the arm can be changed by replacing the counterweight iron block 9 with different weights;

[0053] When the touch switch 7 comes into contact with the bottom wall of the fixed plate 1, the touch switch 7 turns off the electromagnet 17. At this time, the stretching of the patient's arm is no longer carried out, and the sliding plate 13 continues to move, thereby stretching and tractioning the patient's leg. When the air pressure inside the installation box 3 rises to a certain value, the baffle I 19 will move outward under the tension of the tension spring I 21. At this time, the baffle I 19 will block the telescopic cylinder, so that the patient's leg is in a state of being stretched and tractioned;

[0054] After the traction is completed, disassemble and store the connecting rod I 15 and the counterweight iron block 9, and reverse-start the air pump 4. At this time, the air pressure inside the installation box 3 gradually decreases. The tension spring II 22 pulls the baffle II 20 back, and the tension spring I 21 pulls the baffle I 19 back. The gas inside the multi-stage pneumatic telescopic rod 26 and the telescopic cylinder is pumped out through the ventilation hole 23, and the sliding plate 13 enters the fixed plate 1, so as to reset and store the device.

[0055] When the patient lies on the fixing plate 1, fix the electromyogram sensor 28 and the electrode patch of the TENS electrostimulator 27 to the injured part of the patient. When the electromyogram sensor 28 detects muscle tension or spasm of the patient, collect the muscle electrical signal data of the injured part of the patient in real time through the electromyogram sensor 28, and then transmit the muscle electrical signal data to the central processor 29. The central processor 29 controls and turns on the TENS electrostimulator 27 to release low-frequency current to the patient's part to achieve the pain relief effect on the injured part of the patient. The specific steps are as follows:

[0056] Step S1: Data acquisition: Detect the surface electrical signal of the muscle and the real-time muscle state through the electromyogram sensor 28 to generate muscle electrical signal data, and amplify and filter the muscle electrical signal data to generate optimized muscle electrical signal data;

[0057] Step S2: Fuzzification: Convert the optimized muscle electrical signal data into a fuzzy set through the fuzzy membership function. The formula used is as follows:

[0058] ;

[0059] Wherein, represents the optimized muscle electrical signal data, is the mean value of the Gaussian function; is the standard deviation of the Gaussian function; represents the base of the natural logarithm; represents the membership degree value belonging to the fuzzy set;

[0060] Step S3: Fuzzy inference: Define the fuzzy rule base, input the fuzzy set into the fuzzy rule base for inference, and generate a fuzzy control signal;

[0061] Step S4: Adaptive adjustment: Adjust the fuzzy rule base according to the real-time muscle state, optimize the fuzzy control signal, and generate an adaptive adjustment parameter;

[0062] Step S5: Defuzzification: Convert the adaptive adjustment parameter into a control instruction for the TENS electrostimulator 27.

[0063] If those of ordinary skill in the art are inspired by it and design a structural method and an embodiment similar to this technical solution without creative work without departing from the gist of the present invention, they shall fall within the protection scope of the present invention.
