Problems solved by technology

For patients with severe fractures, small splints cannot play a role in traction, and bone traction or skin traction is required, but bone traction or skin traction requires bed rest and heavy objects, and the patient's comfort is poor
[0004] Therefore, there is a lack of a fracture splint that has a good fixation effect and is easy to operate and is suitable for first aid; meanwhile, it can also be used as a splint for preoperative traction

Embodiment 1

[0054] see Figure 1-Figure 5 As shown, the present invention provides a fracture splint, comprising: a plurality of variable-diameter collar bodies, each variable-diameter collar body is arranged at intervals in turn, and each collar body is respectively sleeved in different positions of the limb; multiple lengths Adjustable support rods 4, each support rod 4 is sequentially arranged at intervals along the circumferential direction of the ferrule body, and is perpendicular to the plane where each ferrule body is located, each support rod 4 is connected to each ferrule body respectively, and each ferrule body is limited. The center of the circle of the body is on the same straight line, so as to ensure that the internal limb parts will not be displaced and ensure the safety of the patient.

[0055] see figure 1 As shown, in this embodiment, the fracture splint includes a first collar body 1, a second collar body 2 and a third collar body 3 arranged on both sides of the first ...

Embodiment 2

[0066] see Figure 6 As shown, in the second embodiment, a fracture fixture is provided, which also includes a plurality of variable-diameter ferrule bodies and a plurality of length-adjustable support rods 4, which are different from the second embodiment by adding a spring 7, And the structure of the support rod 4 is different from that of the first embodiment.

[0067] Specifically, the fracture splint includes: a plurality of variable-diameter collar bodies, each variable-diameter collar body is arranged at intervals in turn; a plurality of length-adjustable support rods 4, each support rod 4 is arranged along the circumference of the ferrule body The directions are arranged at intervals in sequence, and are all perpendicular to the plane where each ferrule body is located. Each support rod 4 is respectively connected to each ferrule body, so that the centers of circles of each ferrule body are on the same straight line.

[0068] The fracture fixture includes a first ferr...

Embodiment 3

[0072] see Figure 7 As shown, in the third embodiment, on the basis of the above-mentioned embodiments one and two, the fracture splint also includes a protective cover 8, and the protective cover is a cylindrical structure formed by bending the resettable plate inwardly. A through hole 81 is provided, and the resettable plate 80 is provided with a plurality of strip-shaped plates 83 at intervals along the length direction, and each strip-shaped plate 83 is attached to the resettable plate along the width direction of the resettable plate 80 On the inner surface of the plate 80, a plurality of hollow columns 82 are respectively arranged alternately on the two length sides of the resettable plate 80, and straight rods run through between each hollow column 82, and the straight rods limit the protective cover 9 to maintain a cylindrical structure; the protective cover 9. The inner layer is provided with a flexible skin contact layer, and the first ferrule body 1, the second fer...

Abstract

The invention provides a splint for a bone fracture. The splint comprises a plurality of diameter-changeable ferrule bodies and a plurality of length-adjustable supporting rods, wherein all the diameter-changeable ferrule bodies are sequentially arranged at intervals; and all the supporting rods are sequentially arranged along circumferential directions of the ferrule bodies at intervals and are all vertical to planes where all the ferrule bodies are located, all the supporting rods are separately connected with all the ferrule bodies, and centers of circle of all the ferrule bodies are defined in the same straight line. According to the splint for the bone fracture, provided by the invention, a pressurizing range can be accurately adjusted for effective fixing; the material is modularizedand is easy to produce and assemble; and in addition, the splint for the bone fracture, provided by the invention, has a drawing function while fixing, so that the treatment effect is better, and theexperience of a sufferer is good.

Description

technical field [0001] The invention relates to the technical field of medical machinery, in particular to a fracture splint. Background technique [0002] A fracture is a complete or partial break in the continuity of the bone structure. It is more common in children and the elderly, and it also occurs from time to time in young and middle-aged people. Patients often have a fracture at one site, and a few have multiple fractures. After timely and appropriate treatment, most patients can recover their original functions, and a small number of patients may have sequelae of varying degrees. [0003] At present, clinically, patients with limb fractures generally need to be fixed with traditional splints or casts to ensure that the fractured part of the patient does not dislocate. When using a small splint for fixation, due to the small plasticity of the splint, it is easy to cause displacement when moving, and the fixation effect is not ideal; while plaster fixation needs to...
