Abstract

The utility model discloses a medical shank fixing sleeve. The medical shank fixing sleeve is composed of a sleeve body, air holes, a sleeve opening, a male buckle, a female buckle and an elastic cord, wherein the shape of the sleeve body is matched with the shape of a portion from the shank to the foot of a patient. The sleeve body is made of various modified high polymer materials through injection molding, has X-ray penetrating performance, and is softened in warm water at the temperature between 65 DEG C to 70 DEG C and hardened at room temperature. The sleeve opening of the fixing sleeve which is softened faces the direction of a foot disc and is applied to a fracture portion in an assisted mode. After the fixing sleeve completely is fitted to the shank through proper adjustment, the fixing sleeve is gradually hardened to form a hard sleeve body at the room temperature. After the male buckle and the female buckle are pulled tightly and attached together, the whole fixing sleeve is tightly fixed on the shank and conducts external fixation on the fracture portion. Due to the fact that the air holes are densely formed and the medical shank fixing sleeve has the X-ray penetrating performance, so that excretion of sweat and secreta on affected portions cannot be affected, secondary diseases of a patient cannot be easily caused, and the splint does not need to be dismantled in a reexamination during the period of rehabilitation.

Description

Medical shank fixed cover

Technical field

This utility model relates to a kind of medical instruments, specifically is the medical shank fixed cover of a kind of orthopaedics.

Background technology

For a long time, the hands of human body, foot, shank are in case occur fracturing in the time of need carrying out external fixation, usually after adding water and stir into pasty state with Gypsum Fibrosum powder, spread upon on the gauze bandage, the gauze bandage that will have the Gypsum Fibrosum paste is rolled in fracture site outward, Gypsum Fibrosum is stuck with paste dehydration hardening molding, and fracture site is carried out external fixation.What utilize is that Gypsum Fibrosum powder is met water dissolution, and the furnishing pasty state is convenient to plasticity, by simply wrap up in twine after, just can fit fully with the human body of fracture site, become at once after the dehydration and wrap up in the tubulose duricrust that applies fracture site, with the fracture affected part displacement that prevents from continuing, play the external fixation effect.

The bone injury external fixation system that occurs a kind of crying " AGMA " in recent years on the market again, its principle and application maneuver are identical with right cream, and just material is not Gypsum Fibrosum, but a kind of macromolecular material, meeting water deliquescing, dehydration can hardening, thereby plays the effect of external fixation.

But no matter be to use right cream, still carry out external fixation of fracture with AGMA, all have following 2 critical defectives:

1, can only become tubulose behind the plastotype, and abundant, airtight, sweat and the secretions that discharges in the affected part of can not volatilizing, symptoms such as pruritus, dermatitis appear in the skin in affected part easily, easily cause patient's secondary sufferer and increase the patient body load.

2, because these two kinds of materials all intercept penetrating of x light, for the requisite check midway of patient's rehabilitation course, or the secondary disease of skin occurs and need clear up when treatment, just can carry out after need cutting external fixation system earlier, check or treat the making again that finishes again, both long, waste resource of time increased patient's cost burden again.

Summary of the invention

This utility model provides a kind of processability good, in light weight, intensity height, good permeability, easy to operate medical shank fixed cover.

Medical shank fixed cover of the present utility model is made of body, air-vent, running-on, male and female hasp, elastic cord.The shape of body and patient are suitable to foot by shank, according to the injection mo(u)lding of human leg type curve, have X-ray line penetration performance by multiple modified polymer material, can be softening in the warm water of 65 ~ 70 degree, hardening under room temperature environment, the body after the hardening keep the plastotype shape under the softening situation.

Running-on is arranged on the whole vertical of body from top to bottom, and the corresponding patient's shank of this running-on is to the front of foot.

The air-vent dense distribution is at body, and the male and female hasp is sewn to the position, upper, middle and lower in the body outside by elastic cord.

Getting in advance, injection molding body softens in warm water, running-on is assisted towards foot dish direction and is applied at fracture site, after suitably fine setting makes it to fit in shank fully, macromolecular material progressively hardens into hard body at ambient temperature, after male and female hasp tension pasted, whole fixed cover just is fixed on the human body shank closely, and fracture site is implemented external fixation; Penetrate function because body is intensively distributed with air-vent and possesses the X-ray line, neither influence affected part sweat, secretions drainage, be difficult for causing patient's secondary sufferer, needn't remove fixed cover in the check between convalescence again.

The beneficial effects of the utility model are: prepare fixed cover intensity height, thickness a surname by multiple modified polymer material, reduced patient's heavy burden; The air-vent that gathers does not influence patient's sweat, secretions to be drained, and is difficult for causing secondary dermatosis; Possess the X-ray line and penetrate function, omitted dismounting external fixation thing program during check.

Description of drawings

Accompanying drawing is structural representation of the present utility model.

Among the figure 1, body, 2, air-vent, 3, running-on, 4, the male and female hasp, 5, elastic cord.

The specific embodiment

In the embodiment of accompanying drawing, medical shank fixed cover of the present utility model is made of body 1, air-vent 2, running-on 3, male and female hasp 4, elastic cord 5, its main body be shape and patient by shank to the suitable macromolecule body 1 of foot, at macromolecule body 1 densely covered air-vent 2, body 1 is along the whole running-on 3 that vertically is provided with, these running-on 3 corresponding patient's shanks are to the front of foot, and male and female hasp 4 is sewn to the position, upper, middle and lower in body 1 outside by elastic cord 5.

Body 1 by multiple modified polymer material according to the injection mo(u)lding of human leg type curve, the macromolecular material that constitutes body 1 can be softening in 2 ~ 3 minutes in the warm water of 65 ~ 70 degree, hardening at room temperature 3 ~ 5 minutes, and the plastotype shape under the softening situation of maintenance, the width of running-on 3 is advisable with 30 ~ 40% of patient's correspondence position girth.

Embodiment 1: getting in advance, injection molding body 1 soaked 2 ~ 3 minutes in 65 ~ 70 degree warm water, body 1 becomes software, running-on 3 is clothed to body 1 towards foot dish direction the shank of fracture, according to the shank shape, after body 1 carried out suitable applying fine setting, body 1 just is fitted in fully by whole shank 60 ~ 70% positions of shank to foot, assists and applies fracture site.Because the characteristic of modified polymer material is progressively sclerosis in 3 ~ 5 minutes at ambient temperature, body 1 after the sclerosis just becomes sterosome, end with male and female hasp 4 stretches again, elastic cord 5 is tightened up and tool elasticity, after male and female hasp 4 is pasted, whole fixed cover just is fixed on the human body shank closely, and fracture site is implemented external fixation.

Embodiment 2, if applying trim process overlong time and body 1 has hardened, available hair drier carries out that local warming is softening to continue the fine setting of fitting.

Embodiment 3, assisted the normal sweat of the skin of leg that applies the position, secretions to drain, and discharge at the air-vent 2 of body 1 by dense distribution, are difficult for causing the secondary disease of skin.Just in case pruritus appears in patient skin, dermatitis grade rawhide skin disease needs cleaning, or fully recover when needing to remove fixedly in the affected part, untie male and female hasp 4, arrive greater than the shank diameter more than 50% with hair drier at running-on 3 and depth, it is softening that body 1 is implemented to heat, till whole fixed cover can be peeled off.
