Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a lumbar traction reducer. Background Art

[0002] Lumbar spine disease is a common health problem in modern society, which has a serious impact on the patient's quality of life and work ability. Traditional lumbar spine treatment methods often rely on medication, physical therapy or surgery, but these methods may have limited effects in some cases and have potential risks and inconveniences. Therefore, it is particularly important to develop an efficient, safe and patient-acceptable lumbar traction reduction device.

[0003] In the existing equipment, it is impossible to perform traction according to the strength of the patient's lumbar spine. During the traction process, only moderate strength can be selected for traction. However, during this process, some patients will suffer secondary injuries due to excessive traction force, while some patients will not be able to receive effective treatment due to too small traction force. In addition, the patient will experience pain during the traction process, which will make the patient's muscles tense and cause the traction effect to deteriorate. In addition, the existing equipment cannot adjust multiple angles, and during the traction process, a physiological curvature cannot be formed. Under normal circumstances, the lumbar spine presents an S-shaped curvature with convex front and concave back when viewed from the side. This physiological curvature helps to protect the spinal nerves and enhance the stability and balance of the waist. During the bending process, the front of the lumbar spine will move forward and the back will move backward to form a physiological curvature. This curvature helps to disperse the pressure of the body weight on the lumbar spine, thereby protecting the lumbar spine from injury. At the same time, this bending ability of the lumbar spine also enables the human body to complete various complex movements, such as flexion, extension, lateral bending, etc. During the lumbar spine bending process, the coordination and flexibility of the muscles can be improved, and the deep muscles can also be activated;

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In a typical implementation of this application, please refer to Figures 1 to 8As shown, a lumbar traction reducer comprises: a base 1, support plates 2 are fixedly installed on both sides of the top surface of the base 1, a rotating column 3 is rotatably connected between the two support plates 2, a driving motor 4 is fixedly installed on the side wall of one of the support plates 2, the output shaft of the driving motor 4 is connected to the side wall of the rotating column 3, a sleeve rod 5 is fixedly installed on the outer surface of the rotating column 3, a backrest 6 is fixedly installed on the outer surface of the sleeve rod 5, a contraction groove 7 is opened on the rear side wall of the backrest 6, a shoulder pillow 8 is installed on the rear side wall of the backrest 6 through an adjusting component, a headrest 9 is fixedly installed on the rear side wall of the shoulder pillow 8, and a footrest 10 is installed on the front side wall of the backrest 6 through a rotating component;

[0029] The movable groove 24 is provided on the top surface of the backrest 6 , and a detection component is arranged inside the movable groove 24 .

[0030] As a preferred implementation in this embodiment, please refer to Figure 6 and Figure 7 As shown, the detection component includes: a moving plate 26, which is slidably installed in the moving groove 24 and slides in the moving groove 24. The moving groove 24 is made of iron material. A plurality of electromagnets 27 are fixedly installed on the bottom surface of the moving groove 24. The electromagnets 27 cooperate with the moving groove 24. A mounting groove 28 is provided on the top surface of the moving plate 26. A driving motor 29 is fixedly installed inside the mounting groove 28. The output shaft of the driving motor 29 is rotatably connected to a massager 30. An ultrasonic sensor 31 is fixedly installed on the top surface of the moving plate 26 on one side of the massager 30. The detection component also includes: an optical sensor 32, which is fixedly installed on the rear side wall of the moving plate 26. A plurality of micro electric push rods 33 are fixedly installed on the top surface of the moving plate 26, and a plurality of micro electric push rods 33 are fixedly installed on the top surfaces of the plurality of micro electric push rods 33. Pressure sensors 34 are fixedly installed on the top surfaces of the plurality of micro electric push rods 33.

[0031] Through the above features, the strength of the patient's lumbar spine can be detected, the patient's waist can be massaged and relaxed, and the fit between the patient's lumbar spine and the backrest 6 can be detected. Specifically, when the patient lies on the backrest 6 and the shoulder pillow 8, the electromagnets 27 are started in sequence to move the movable plate 26 in the movable groove 24. At this time, the drive motor 4 29 works to make the massager 30 connected to the output shaft of the drive motor 4 29 rotate synchronously. The massager 30 has a heating function, so that the massager 30 can massage and relax the patient's waist. In this process, multiple micro-electric push rods 33 will rise upward to squeeze the pressure sensor 34 against the patient's waist. The massager 34 is squeezed to detect whether the patient's waist is relaxed. If it is detected that the patient is not relaxed here, the massager 30 will stay here until the patient is relaxed. During this process, the ultrasonic sensor 31 will continue to work to detect the strength of the patient's lumbar spine and transmit its data to the adjustment component, so that it can adjust it according to the strength of the patient's lumbar spine to avoid damage to the patient's lumbar spine during the adjustment process. During this process, the optical sensor 32 will detect the fit between the patient's waist and the backrest 6. If it is detected that it does not fit the backrest 6, it will transmit data to the rotating component to make it work to lift the patient's lower body so that it is completely in contact with the top surface of the backrest 6.

[0032] It is worth mentioning that when the patient's waist is relaxed, it usually means that the back and waist muscles are in a relatively relaxed state. At this time, the micro electric push rod 33 makes the pressure sensor 34 and the patient's waist squeeze relatively evenly, and the pressure sensor 34 is subjected to a small squeezing force. On the contrary, when the waist is tense or exerts force, the micro electric push rod 33 makes the pressure sensor 34 and the patient's waist squeeze unevenly, and the pressure sensor 34 is subjected to a large squeezing force, thereby detecting whether the patient's waist is relaxed;

[0033] The ultrasonic sensor 31 can penetrate the soft tissues of the human body, such as muscles, fat, etc., and reach the surface of the bones. When the ultrasonic wave encounters the bones, part of the sound wave will be reflected back. The parameters such as the intensity, frequency and phase of the reflected wave are related to the characteristics of the bones such as density, structure and strength. The propagation speed of the ultrasonic wave in the bones and the attenuation during the propagation process are also related to the strength of the bones. Generally speaking, the higher the bone strength, the faster the propagation speed of the ultrasonic wave and the smaller the attenuation. By collecting the information of the reflected wave and the propagation process, the ultrasonic image of the lumbar spine can be constructed to adjust the strength of the adjustment component to avoid causing secondary injury to the patient. When the ultrasonic sensor 31 is working, the moving plate 26 is in a stopped state to avoid it not receiving the reflected signal;

[0034] The optical sensor 32 can be a laser sensor, an infrared sensor or an optical image sensor. The laser sensor emits a laser beam to the patient's body on the backrest 6. The laser beam will be reflected when it encounters the surface of an object. The sensor receives the reflected light and calculates the round-trip time or phase difference of the laser beam, thereby determining the distance between the patient's body and the backrest 6. By analyzing these distance data, it can be determined whether the patient is in close contact with the backrest 6; the infrared sensor monitors the infrared radiation emitted by the patient's body or the reflected infrared light. When the patient is in close contact with the backrest 6, the distribution and intensity of the infrared radiation will change, such as decreasing or becoming uniform. By detecting these changes, it can be determined whether the patient is in close contact with the backrest 6; the optical image sensor captures the image of the patient and the backrest 6, and extracts the contours of the patient's body and the backrest 6 through image processing techniques such as edge detection and contour extraction. By comparing the relative position and shape relationship between the two, it can be determined whether the patient is in close contact with the backrest 6.

[0035] As a preferred implementation in this embodiment, please refer to Figure 2 to Figure 5 As shown, the adjustment component includes: a cylinder 11, which is fixedly installed inside the contraction groove 7, a cylinder 12 is fixedly installed on the output shaft of the cylinder 11, an iron ball 13 is movably installed inside the cylinder 12, a plurality of electromagnets 14 are arranged inside the cylinder 12, a concave plate 15 is fixedly installed on the side wall of the iron ball 13, a rotating column 16 is rotatably connected to the groove of the concave plate 15, a sleeve rod 17 is fixedly installed on the outer surface of the rotating column 16, a connecting rod 18 is fixedly installed on the outer surface of the sleeve rod 17, one side of the connecting rod 18 is connected to the front side wall of the shoulder pillow 8, a driving motor 19 is fixedly installed on the side wall of the concave plate 15, and the output shaft of the driving motor 19 is connected to the side wall of the rotating column 16.

[0036] Through the above-mentioned features, the patient can be pulled in multiple directions. Specifically, the medical staff turns on the cylinder 11, so that the cylinder 12 and the iron ball 13 connected to the output shaft of the cylinder 11 extend out at the same time. When the iron ball 13 rises, the concave plate 15 will also extend synchronously. At this time, the rotating column 16, the sleeve rod 17 and the connecting rod 18 connected to the concave plate 15 will drive the connecting rod 18 to rise, so that the patient is pulled laterally. If multi-angle adjustment is required, the electromagnet 14 in the cylinder 12 can be turned on in sequence, so that the iron ball 13 rotates in the cylinder 12, and the iron ball 13 can drive the shoulder pillow 8 to rotate. If the shoulder pillow 8 needs to be bent, it is only necessary to engage the driving motor 19 to rotate the rotating column 16 connected to the output shaft of the driving motor 19. When the rotating column 16 rotates, the sleeve rod 17 and the connecting rod 18 will be driven to rotate synchronously, so that the shoulder pillow 8 connected to the connecting rod 18 can be bent.

[0037] As a preferred implementation in this embodiment, please refer to Figure 1 and Figure 2As shown, the rotating assembly includes: two connecting plates 20, the two connecting plates 20 are respectively fixedly mounted on the two ends of the front side wall of the backrest 6, a rotating column three 21 is rotatably connected between the two connecting plates 20, a sleeve rod three 22 is fixedly mounted on the outer surface of the rotating column three 21, a driving motor three 23 is fixedly mounted on the side wall of one of the connecting plates 20, the output shaft of the driving motor three 23 is connected to the side wall of the rotating column three 21, and the outer surface of the sleeve rod three 22 is connected to the rear side wall of the foot rest 10.

[0038] Through the above-mentioned features, the angle of the footrest 10 can be adjusted. Specifically, when adjustment is needed, it is only necessary to turn on the driving motor 3 23 to rotate the rotating column 3 21 connected to the output shaft of the driving motor 3 23, so that the sleeve rod 3 22 connected to the outer surface of the rotating column 3 21 drives the footrest 10 to be adjusted.

[0039] As a preferred implementation in this embodiment, please refer to Figure 1 , Figure 2 , Figure 3 ,and Figure 6 As shown, a textile mesh 35 is fixedly installed on the side wall of the movable groove 24, and a detection port 36 is opened on the top surface of the textile mesh 35. The above features can make the patient more comfortable, and the problem that the ultrasonic sensor 31 cannot detect can be avoided by providing the detection port 36.

[0040] As a preferred implementation in this embodiment, please refer to Figure 1 to Figure 3 As shown, at least one set of safety belts 37 and buckles 38 are fixedly installed on the backrest 6, shoulder pillow 8 and foot rest 10. Through the above features, the safety belts 37 and buckles 38 can cooperate with each other to fix the patient on the backrest 6, shoulder pillow 8 and foot rest 10, avoiding poor traction effect caused by the patient's movement.

[0041] As a preferred implementation in this embodiment, please refer to Figure 6 As shown, both side walls of the movable groove 24 are provided with limiting grooves 25, and both side walls of the movable plate 26 are fixedly installed with limiting blocks 39, and the limiting blocks 39 slide in the limiting grooves 25. The above features can limit the movable plate 26 to prevent the movable plate 26 from sliding out of the movable groove 24.

[0042] Working principle:

[0043] When in use, firstly, the whole device is firmly supported by the base 1, the patient lies on the backrest 6 and the shoulder pillow 8, and fastens the safety belt 37 and the buckle 38 to ensure stability during the traction process, the electromagnet 27 is started in sequence, attracting the movable plate 26 to slide in the movable groove 24, and the driving motor 4 29 on the movable plate 26 drives the massager 30 to rotate, so as to massage and relax the patient's waist. At the same time, multiple miniature electric push rods 33 are raised to make the pressure sensor 34 contact with the patient's waist, and judge whether the waist is relaxed by detecting the squeezing force, the ultrasonic sensor 31 continues to work, penetrates the soft tissue to reach the bone surface, collects the reflected wave information, and constructs the ultrasonic image of the lumbar spine to evaluate the strength of the lumbar spine, the optical sensor 32 can be a laser, infrared or image sensor to detect the fit between the patient's waist and the backrest 6 to ensure the traction effect, and the medical staff turns on the cylinder 11 to make the cylinder 12 As the iron ball 13 extends out, it drives the concave plate 15, the rotating column 16, the sleeve rod 17 and the connecting rod 18 to move synchronously to achieve lateral traction for the patient. If multi-angle adjustment is required, the electromagnet 14 can be turned on in turn to make the iron ball 13 rotate in the cylinder 12, driving the shoulder pillow 8 to rotate. If the shoulder pillow 8 needs to be bent, start the drive motor 2 19 to rotate the rotating column 16, driving the sleeve rod 17 and the connecting rod 18 to rotate synchronously. When the angle of the footrest 10 needs to be adjusted, turn on the drive motor 3 23 to rotate the rotating column 3 21, driving the sleeve rod 3 22 and the footrest 10 to adjust, so as to ensure that the patient's lower body is in a comfortable and effective traction position. The design of the textile mesh 35 and the detection port 36 makes the patient more comfortable while ensuring that the ultrasonic sensor 31 can detect normally. The limit groove 25 and the limit block 39 limit the movable plate 26 to prevent it from slipping out of the movable groove 24.
