Embodiment 1

[0042] Such as figure 1 As shown, the two sides of the floor bed 1 in this embodiment are fixed with support columns 2 by bolts. The interior of the support columns 2 is hollow, and the inner side is fixed with a bracket 3 through metal spring pins 12, and two sets of pulley assemblies 4 are movable on the bracket 3. , the lower side of the pulley assembly 4 is connected to the foot plate 5 through the sling 20, and the lower side of the foot plate 5 is provided with an air pressure suspension device 6.

Embodiment 2

[0044] Such as Figure 2-Figure 3 As shown, the floor bed 1 of the present embodiment is made of rectangular plank 7, metal frame, guardrail 10, iliac crest band 9 and soft mattress 8. Its main body is a rectangular plank 7, and the periphery is with a metal frame, so that the guardrail 10, iliac crest band 9 and support column 2 can be firmly fixed on the main body with screws. The central area of ​​the inner surface of the iliac crest band 9 is a dumbbell-shaped anti-pressure sore liner 11. The effect of the iliac crest band 9 is to assist in fixing the child, preventing it from crying and turning over to cause new trauma and induce pain at the fracture site. It has the effect of resisting traction. When the maximum suspended traction load cannot correct limb shortening, the traction can be counteracted by tightening the iliac girdle 9 rows.

Embodiment 3

[0046] Such as Figure 4As shown, the support column 2 of this embodiment is mainly composed of a square metal hollow rod and a spring pin 12 . The lower end of the metal rod is connected with the floor bed 1 by screws, and its upper end has a metal spring latch 12 for connecting and fixing the support 3.

Abstract

The invention belongs to the technical field of fracture suspension traction devices, and discloses an adjustable child femoral fracture suspension traction system and a control method. Supporting columns are fixed to two sides of a baseboard bed through bolts, the supporting columns are hollow, a support is fixedly sleeved with the supporting columns through metal spring cotters, two sets of pulley assemblies are movably arranged on the support, foot plates are connected with the lower sides of the pulley assemblies through slings, and air pressure suspension devices are arranged on the lowersides of the foot plates; and the baseboard bed comprises a rectangular plank, a soft mattress is arranged on the upper side of the rectangular plank, a metal frame is arranged on the periphery of the soft mattress, guard bars are arranged on two sides of the mattress, and an ilium band is arranged on the upper side of the middle portion of the mattress. According to the adjustable child femoralfracture suspension traction system and the control method, the structure is simple and reasonable, multi-angle traction can be achieved through the foot plates and the air pressure suspension devices, rotation deformity and lateral angulation deformity can be corrected controllably, a child patient is fixed by the ilium band, and secondary injury due to squirming of the child patient is prevented, so that the safety is high.

Description

technical field [0001] The invention belongs to the technical field of suspension and traction devices for fractures, and in particular relates to an adjustable suspension and traction system for children with femur fractures and a control method. Background technique [0002] Currently, the femur is the largest tubular bone in the human body, surrounded by abundant muscles. During development, the femur forms a lordosis, with pressure on the inside and tension on the outside. Femoral shaft fractures in children are common clinical fractures. There are three main treatments for this disease: traction, external fixation, and internal fixation. For children under 5 years old, suspension skin traction is often used. [0003] Suspension skin traction is to draw the lower limbs with the skin, and both legs go up at the same time, adjust the traction weight until the buttocks are slightly away from the bed, and use the weight of the body as the anti-traction. [0004] At present...
