Abstract

The utility model discloses a medical high polymer fixed splint. The medical high polymer fixed splint comprises a splint body, air holes, a male buckle, a female buckle and an elastic cord, wherein the splint body is a rectangular thin plate, is made of various modified high polymer materials through calendaring molding, has X-ray penetrating performance, and is softened in warm water at temperature between 65 DEG C to 70 DEG C and hardened at room temperature. The splint body which is molded in a calendaring mode in advance is softened after being placed in the warm water, the fixed splint is cut into a splint with the size being approximately equal to two thirds of the perimeter of limbs in a fracture portion, and the splint is applied to the fracture portion in an assisted mode. After the splint is fitted to curves of the limbs and shapes, the high polymer materials are gradually hardened to form a hard splint body at the room temperature. After the male buckle and the female buckle are pulled tightly and attached together, the high polymer material fixed splint can be tightly fixed on the limbs and conducts external fixation on the fracture portion. Due to the fact that the air holes are densely formed in the splint body and the medical high polymer fixed splint 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

The medical high polymer strap

Technical field

This utility model relates to a kind of medical instruments, specifically is a kind of orthopaedics medical high polymer strap.

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 critical defective:

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, when checking for patient's rehabilitation course is requisite midway, 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 high polymer strap.

Medical high polymer strap of the present utility model is made of plate body, air-vent, male and female hasp, elastic cord.Plate body is the rectangle thin plate, by multiple modified polymer material calendering formation, has X-ray line penetration performance, can be softening in the warm water of 65 ~ 70 degree, but cutting under the soft state, hardening under room temperature environment, the plastotype shape the when plate body after the hardening keeps softening situation.

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

Getting in advance, the plate body of calendering formation softens in warm water, by the dimensional standard that approximates fracture site limbs girth 2/3rds strap is carried out cutting, clamping plate are assisted apply at fracture site, fit behind the limbs curve plastotype, macromolecular material progressively hardens into hard plate body at ambient temperature, after male and female hasp tension pasted, whole macromolecule fixedly clamping plate just was fixed on human body limb closely, to fracture site enforcement external fixation; Penetrate function because plate 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 clamping plate in the check between convalescence again.

The beneficial effects of the utility model are: strap intensity height, thickness a surname by multiple modified polymer material preparation, 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, plate body, 2, air-vent.

The specific embodiment

In the embodiment of accompanying drawing, medical high polymer strap of the present utility model is made of plate body 1, air-vent 2, male and female hasp, elastic cord, its main body is the macromolecule plate body 1 of rectangularity, at macromolecule plate body 1 densely covered air-vent 2, the male and female hasp is sewn to the position, upper, middle and lower in plate body 1 outside by elastic cord.

Plate body 1 is the thick rectangle thin plate of 3mm by multiple modified polymer material calendering formation, and the macromolecular material that constitutes plate 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.

Embodiment 1: getting in advance, injection molding plate body 1 soaked 2 ~ 3 minutes in 65 ~ 70 degree warm water, plate body 1 becomes software, by the dimensional standard that approximates fracture site limbs girth 2/3rds strap is carried out cutting, plate body 1 is fitted behind the fracture site limbs curve plastotype, plate body 1 just is fitted in human body limb fully, assists and applies fracture site.Because the characteristic of modified polymer material is progressively sclerosis in 3 ~ 5 minutes at ambient temperature, plate body 1 after the sclerosis just becomes sterosome, end with the male and female hasp stretches again, elastic cord is tightened up and tool elasticity, after the male and female hasp is pasted, strap behind the whole plastotype just is fixed on human body limb closely, and fracture site is implemented external fixation.

Embodiment 2, and plate body 1 has hardened if applying plastotype process time is long, and available hair drier carries out local warming's softening continuation applying fine setting.

Embodiment 3, assisted the normal sweat, the secretions that apply position skin to drain, and discharge at the air-vent 2 of plate 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 the male and female hasp, with hair drier at plate body 1 edge and depth to greater than fracture site limbs diameter more than 50%, it is softening that plate body 1 is implemented to heat, till whole clamping plate can be peeled off.
