[0028] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0029] Example:

[0030] like Figures 1 to 5 As shown, this application discloses a traction device for a traction bed, comprising: a base plate 200, which serves as the basic support structure for the entire traction device, ensuring its stability and load-bearing capacity. The bottom of the base plate 200 is also equipped with an anti-slip pad, allowing for stable placement after installation on a hospital bed or traction bed; and a leg support plate 300, installed above the base plate 200. The leg support plate 300 is configured to move closer to or further away from the base plate 200, and a skin traction device 400 is provided on the leg support plate 300. The leg support plate 300 supports the patient's legs, achieving traction of the patient's lower limbs. The leg support plate 300 can be adjusted to move closer to or further away from the base plate 200 according to the patient's height and traction needs. The traction system improves flexibility and comfort. The skin traction 400 acts directly on the patient's legs, transmitting traction force through the traction rope 500, providing stable and uniform traction force, which helps relieve lumbar or lower limb pain and promotes recovery. The traction rope 500 is connected to the skin traction 400 at one end and extends beyond one side of the leg support plate 300, set at the bottom of the leg support plate 300 at the other end. The winding wheel 505 is installed at the bottom of the leg support plate 300 and is used to wind the traction rope 500. The traction rope 500 plays a role in transmitting traction force. By controlling the rotation of the winding wheel 505, precise control of the traction force can be achieved, improving the traction effect.

[0031] See Figure 3The base plate 200 of this application includes: a first guide wheel 501, installed above the base plate 200, with the traction rope 500 resting on the first guide wheel 501; a second guide wheel 503, installed at the end of the leg support plate 300, with the traction rope 500 resting on the second guide wheel 503; a first support frame 502, installed on the top of the base plate 200, with the first guide wheel 501 installed on the first support frame 502; and a second support frame 504, installed at the bottom of the base plate 200, with the winding wheel 505 installed on the second support frame 504. The first guide wheel 501 and the second guide wheel 503 reduce the friction and wear of the traction rope 500 during transmission, extending the service life of the traction rope 500.

[0032] See Figure 5 The second support frame 504 of this application includes: a worm gear 506, disposed on one side of the second support frame 504, the worm gear 506 being connected to the winding wheel 505 via a rotating shaft; a rotating rod 507, passing through the leg support plate 300; a worm 508, installed at the bottom end of the rotating rod 507, the worm 508 being connected to the worm gear 506; and a traction knob 509, installed at the top end of the rotating rod 507. The worm gear 506 and the worm 508 form the driving mechanism of the winding wheel 505, which can be driven by rotating the traction knob 509. The worm 508 rotates, which in turn drives the worm wheel 506 and the winding wheel 505 to rotate. The worm wheel 506 and the worm 508 have a self-locking structure. Without actively rotating the traction knob 509, the worm wheel 506 will not drive the worm 508 to rotate. Only when the traction knob 509 is actively rotated, and the traction knob 509 drives the rotating rod 507 and the worm 508 to rotate, will the worm 508 drive the worm wheel 506 to rotate. This achieves precise adjustment of the length of the traction rope 500, improving the accuracy and comfort of traction.

[0033] See Figure 3The base plate 200 of this application includes: two movable seats 202, which are mounted on the top of the base plate 200 and are configured to move closer to or further away from each other simultaneously; two connecting plates 203, one end of which is connected to the two movable seats 202 respectively, and the other end of which is connected to the bottom of the leg support plate 300 respectively; an adjustment groove 201, which is formed on the top of the base plate 200, and the two movable seats 202 are connected to the adjustment groove 201; and two lead screws 204, which are disposed in the adjustment groove 201 and pass through the two movable seats 202 respectively. One of the lead screws 204 is connected to an adjustment knob 206 for adjustment. A knob 206 is located on one side of the base plate 200. Two lead screws 204 are connected to gears 205 at their close ends. The two gears 205 mesh with each other. The adjustment groove 201 provides a sliding track for the movable seat 202. The lead screws 204 and gears 205 form a transmission mechanism. By rotating the adjustment knob 206, the two movable seats 202 can be driven to move closer or further apart at the same time. When one lead screw 204 and gear 205 rotate, the other gear 205 will rotate in the opposite direction, causing the two lead screws 204 to rotate in opposite directions. When the two movable seats 202 move closer together, they can drive the two connecting plates 203 to rotate and lift the leg support plate 300. When the two movable seats 202 move further apart, they can drive the two connecting plates 203 to rotate and lower the leg support plate 300.

[0034] See Figure 1 In this application, the traction bed 100 and the base plate 200 are mounted on the traction bed 100, serving as the carrier of the entire traction device and providing an installation platform for the base plate 200 and other components.

[0035] The working principle of this application is as follows: During use, the base plate 200 is installed on the traction bed board 100, ensuring that the base plate 200 is stable and the anti-slip pad is in close contact with the bed surface to prevent slippage during use. The position of the leg support plate 300 is adjusted according to the patient's height and traction needs. By rotating the adjustment knob 206, the screw 204 and gear 205 transmission mechanism are driven, causing the two moving seats 202 to move closer or further apart within the adjustment groove 201, thereby raising or lowering the connecting plate 203 and the leg support plate 300 until a suitable traction height is reached. The patient lies on the traction bed with both legs placed on the leg support plate 300, ensuring close contact between the legs and the skin traction 400. The traction force is adjusted by rotating the traction knob 509 according to the patient's specific condition and the doctor's advice. When the traction knob 509 is rotated, the worm gear 508... The worm gear 506 rotates, which in turn drives the winding wheel 505 to rotate, releasing or tightening the traction rope 500 to achieve precise control of the traction force. Traction treatment begins once patient comfort and appropriate traction force are ensured. The traction rope 500 tightly connects the skin traction 400 to the patient's leg. The traction force transmitted through the traction rope 500 provides stable and even traction to the patient's lower limbs. During traction, medical staff can observe the patient's reaction and traction effect at any time and make fine adjustments as needed. If the traction force needs to be adjusted, simply rotate the traction knob 509 again. After traction treatment, first release the traction force by rotating the traction knob 509, then adjust the leg support plate 300 to its initial position so the patient can easily move out. Disassemble the base plate 200 and other components, clean and disinfect the device for next use.

[0036] In summary, compared with existing technologies, it has the following beneficial effects:

[0037] By adjusting the rotation of the winding wheel 505, the length of the traction rope 500 can be precisely controlled, and the traction force can be flexibly adjusted. This allows medical staff to accurately adjust the traction force according to the individual differences of patients, ensuring that each patient receives the most suitable traction treatment.

[0038] The traction force can be easily adjusted by rotating the traction knob 509, which simplifies the operation process and improves work efficiency. The leg support plate 300 can be adjusted up and down according to the patient's height and traction needs, so that the traction device can better adapt to the patient's body characteristics.
