Description

Technical Field

[0001] The invention relates to the technical field of cervical and lumbar traction beds for traditional Chinese medicine, and in particular to a cervical and lumbar traction bed. Background Art

[0002] TCM rehabilitation refers to the use of various TCM-specific rehabilitation methods and other useful measures under the guidance of TCM theory to reduce the impact of functional disorders and enable people to return to society for the disabled, elderly people, chronic diseases and those in the late stage of acute diseases. In the rehabilitation treatment of patients with cervical and lumbar spine injuries, cervical and lumbar traction beds are often used. The cervical and lumbar traction bed is mainly composed of a fixed bed and a movable bed. The movable bed is raised and lowered to change the angle of the patient's cervical and lumbar spine, thereby performing rehabilitation treatment.

[0003] The existing cervical and lumbar traction beds adopt a mechanical structure, which achieves the treatment of cervical and lumbar vertebrae by changing the angle of the movable bed body through external mechanisms. The existing traction bed has a single traction mode. Due to different lying postures and the different normal body curves of the human body, it is impossible to switch between multiple traction modes such as prone, supine and side-lying. In addition, each patient can withstand different traction angles and strengths, and the angle needs to be adjusted manually according to the patient's own situation.

[0004] A cervical and lumbar traction bed for traditional Chinese medicine rehabilitation with publication number CN112972092A comprises a bed body and two groups of adjustment devices symmetrically arranged on both sides of the bed body; the bed body comprises a U-shaped support frame, an arc plate, and a rotating plate and a fixed plate arranged at both ends of the arc plate; a support plate is arranged at one end of the bottom of the fixed plate through a plurality of support rods, and the bottom of the arc plate is arranged on the top of the support plate through a lifting device; the two sides of the rotating plate are respectively connected to the two sides of the U-shaped support frame near one end of the arc plate through a first rotating shaft; each group of adjustment devices comprises a slide, a first connecting rod and a second connecting rod; a slider is slidably arranged in the slide body, and a second rotating shaft is fixedly arranged on the outer side thereof; the two ends of the first connecting rod are respectively connected to the second rotating shaft and one end of the second connecting rod; the other end of the second connecting rod is connected to the first rotating shaft for rotation. The device can realize traction rehabilitation training in various lying positions, and can autonomously control the traction angle to realize safer, more stable and controllable cervical and lumbar traction rehabilitation training.

[0005] The above equipment can realize traction rehabilitation training in various lying positions, but it is not conducive to quickly adjusting the lumbar angle and effectively traction and stretching the cervical spine, so it needs to be improved. Summary of the invention

The pushing mechanism includes a second hydraulic cylinder assembly 19 installed on the carrier 15, and a connecting plate 18 is fixed to the end of the piston rod of the second hydraulic cylinder assembly 19. The lead screw 17 and the connecting plate 18 are fixedly connected. Through the telescopic operation of the second hydraulic cylinder assembly 19, the lead screw 17 can be driven to reciprocate through the connecting plate 18 to effectively control the rotation direction of the gear member 26 and the movement direction of the arc-shaped inner gear ring member 13.

[0050] Reference Figure 1 , 25. A connecting frame 16 is installed at the upper end of the carrier frame 15, and a screw nut member 25 is rotatably sleeved in the connecting frame 16.

The gear member 26 and the arcuate inner gear ring member 13 are meshed, and the arcuate inner gear ring member 13 is slidably installed on the connecting frame 16, which helps to ensure that the arcuate inner gear ring member 13 can operate stably relative to the connecting frame 16. When the screw 17 moves back and forth, the screw nut member 25 will drive the gear member 26 to rotate back and forth smoothly, which can drive the arcuate inner gear ring member 13 to rotate the first pad 3, and the first pad 3 can rotate relative to the first pad 3, which can simulate the patient's twisting waist and improve the range of lumbar traction.

[0051] Reference Figure 1 , 2 , 3, 6, a plug-in shaft 27 is fixed to one end of the second pad 7 close to the first pad 3, one end of the plug-in shaft 27 is fixed to the first pad 3, the plug-in shaft 27 and the arc-shaped inner gear ring 13 are coaxially arranged, after the plug-in shaft 27 is installed, the first pad 3 can only rotate around the plug-in shaft 27, and at the same time, when the second pad 7 rotates, the first pad 3 will also follow the operation.

[0052] In the present invention, the universal wheel 5 can facilitate the staff to push the equipment to move, and by adjusting the distance between the screw foot piece 11 and the base layer, it can be controlled whether the traction bed can be moved, and the bed body can be quickly moved to a suitable position for the patient to use. At the same time, it can be quickly adjusted to ensure the overall stability and avoid shaking during the use process. The mounting frame 9 can be lifted and lowered relative to the base 4 through the action of the lifting hydraulic cylinder assembly 22, and the position height of the head pillow 1, the first pad 3 and the second pad 7 can be adjusted as needed to adapt to different patients, so that different patients can lie down quickly on the head pillow 1, the first pad 3 and the second pad 7.

When in use, the patient can hold the handle 6 to achieve relative stability of the upper body part, and can make the upper body part rotate synchronously with the first pad 3 and relatively stable relative to the first pad 3. When in use, the head traction component 2 is set on the patient's chin, and the cervical vertebrae are stretched by adjusting the distance between the head pillow 1 and the first pad 3;

[0053] Through the sliding installation between the gear member 26 and the arc-shaped inner gear ring member 13, it can be effectively ensured that the arc-shaped inner gear ring member 13 can stably drive the first pad 3 to rotate. Through the telescopic operation of the second hydraulic cylinder assembly 19, the lead screw 17 can be driven to reciprocate through the connecting plate 18 to effectively control the rotation direction of the gear member 26, the movement direction of the arc-shaped inner gear ring member 13 can be controlled, and the first pad 3 can be rotated relative to the second pad 7, which can simulate the twisting of the waist;

[0054] The arc-shaped inner gear ring member 13 is slidably mounted on the connecting frame 16, which helps to ensure that the arc-shaped inner gear ring member 13 can operate stably relative to the connecting frame 16. When the lead screw 17 moves back and forth, the lead screw nut member 25 drives the gear member 26 to rotate back and forth smoothly, which can drive the arc-shaped inner gear ring member 13 to rotate the first pad 3, and the first pad 3 can rotate relative to the first pad 3, which can simulate the patient's twisting waist and improve the range of lumbar traction;

[0055] When the plug-in shaft 27 is installed, the simulated waist twisting can also be completed, but the second pad 7 and the first pad 3 can realize synchronous rotation, and the simulated patient suspension can be supported by the head traction component 2 to provide traction for the cervical spine.
