[0017] Regarding the drawback that the special suspension traction device for pediatric orthopedics in the prior art is not easily stored properly. After careful analysis by the inventor, it is found that the main reason for the above technical problem is the characteristics of the volume and shape of the special suspension traction device for pediatric orthopedics, which makes the device occupy a large space when not in use and is not easily stored properly. Based on the above analysis, the inventor designs a pediatric traction device that can be folded and stored to reduce the storage space.

[0018] Such as Figures 1 to 2As shown in the figure, in the first embodiment of the present utility model, the pediatric traction device includes a bed board 1, a traction frame 2, a traction rope 3, and a plurality of guide wheels 4 provided on the traction frame 2. The guide wheels 4 are slidably connected to the traction rope 3. The traction frame 2 includes two U-shaped brackets 21 and a fastener 22. The U-shaped brackets 21 have openings facing downward and are hinged to the bed board 1. The fastener 22 is installed between the U-shaped brackets 21 and the bed board 1 and is used to fasten the U-shaped brackets 21.

[0019] Among them, the U-shaped bracket 21 includes a cross bar 23 and telescopic rods 24 provided at both ends of the cross bar 23. The telescopic rods 24 are hinged to the bed board 1, and the guide wheels 4 are installed on the cross bar 23. The bed board 1 is provided with a groove-shaped pivot seat 11. One end of the telescopic rod 24 is inserted into the groove of the pivot seat 11, and the pivot seat 11 is provided with a pivot shaft passing through both sides of the pivot seat 11 and the telescopic rod 24. The U-shaped bracket 21 adopts the telescopic rod 24, which can not only adjust the U-shaped bracket 21 according to the traction treatment situation, but also can shrink the U-shaped bracket 21 when the pediatric traction device is not in use, reducing the storage space and making it easy to be stored. The guide wheel 4 is detachably connected to the traction frame 2 through a fastener. The fastener includes a buckle seat, a buckle cover, and a lock. One end of the buckle cover is hinged to the buckle seat, and the other end is detachably connected to the buckle seat through the lock. The lock includes a pull rod hinged to the buckle seat and a nut provided on the pull rod. The pull rod is provided with an external thread corresponding to the nut, and the buckle cover is provided with an opening that can allow the pull rod to be inserted. Since the guide wheel 4 is detachable, the position of the guide wheel 4 on the traction frame 2 is adjustable, which is suitable for different patients.

[0020] The fastener 22 is a support. The support is sleeved on the telescopic rod 24 and is threadedly connected thereto. After rotating the support, the bottom of the support fits with the bed board 1. The support is in a frustum shape, and the large end of the support fits with the bed board 1. A circular ring 25 protrudes from the side wall of the large end of the support. The bottom of the circular ring 25 is flush with the bottom of the support, and a plurality of reinforcing ribs 26 are provided at intervals on the top of the circular ring 25. Rotate the support clockwise so that the large end of the support fits with the bed board 1, realizing that the support supports the U-shaped bracket 21 and the U-shaped bracket 21 is not easy to rotate. Rotate the support counterclockwise so that the support is away from the bed board 1, enabling the U-shaped bracket 21 to lie flat on the bed board 1, reducing the storage space and making it easy to be stored.

[0021] As Figure 3 shown, the difference between the second embodiment and the first embodiment lies in the fastener 22. The fastener 22 is a sleeve. The bed board 1 is provided with an annular groove 12. One end of the sleeve is sleeved on the telescopic rod 24 and is threadedly connected thereto, and the other end can be inserted into the annular groove 12 and is threadedly connected to the bed board 1. A layer of anti-slip pad is covered on the outer surface of the sleeve. Rotate the sleeve clockwise so that the sleeve is not only threadedly connected to the telescopic rod 24 but also threadedly connected to the bed board 1, and the U-shaped bracket 21 can be fixed and the U-shaped bracket 21 is not easy to rotate. Rotate the sleeve counterclockwise so that the sleeve is away from the bed board 1, enabling the U-shaped bracket 21 to lie flat on the bed board 1, reducing the storage space and making it easy to be stored.

[0022] The usage method of this pediatric traction device is as follows:

[0023] First, place the bed board 1 on a hospital bed or a traditional bed. Secondly, rotate the U-shaped bracket 21 to a position perpendicular to the bed board 1 and fix the U-shaped bracket 21 using the fastener 22. Then, install the guide wheel 4 at a suitable position according to the patient's condition. Finally, install the traction rope 3 on the guide wheel 4, tie one end of the traction rope 3 to the patient's lower limb, adjust the patient's body position to lift the lower limb, hang the counterweight on the other end of the traction rope 3, and use the counterweight to traction the patient's lower limb.

[0024] All of the above embodiments are exemplary rather than restrictive. Those skilled in the art, under the concept of the present utility model, any modifications or deformations made to the specific embodiments described above shall fall within the protection scope of the present utility model.
