Description
Technical field
The invention belongs to field of medical article technology, the preparation method relating to a kind of plaster bandage.
Background technology
Plaster bandage is a kind of conventional products that medical industry is often used, and is mainly used in limbs bone injury repairing and treating.Traditional method producing plaster bandage mainly employing calcium plaster is coated to be dried on gauze and is cut, and the Chinese invention patent production of pypsum bandage if the patent No. is 97115856.8 adopts this process route.But traditional medical plaster bandage has obvious shortcoming, such as ventilative, poisture-penetrability is poor, poor flexibility, during wrapping, to bandage before gypsum, generally to wrap in 5min, it is pressed for time, for some new hands, is difficult to grasp elasticity, tension, cause patient uncomfortable, excessive compression wound, impact recovers, cross pine, do not reach desirable fixed effect.Get wet use time, Gypsum Fibrosum easily occur layering, cause that fixed effect is greatly reduced.
Summary of the invention
It is an object of the invention to provide a kind of plaster bandage, adopt and there is elastic gauze as base fabric on wrapping direction, and the structure of gauze is rationally set, elastic bunch rational deployment, elastic force can not only be provided to binder, but also by its tension force, Gypsum Fibrosum can be wrapped up, Gypsum Fibrosum not easily drops, and will not be layered during use.
In order to achieve the above object, the present invention adopts the following technical scheme that: the preparation method of a kind of plaster bandage, comprise the steps: (1) braiding base fabric, base fabric by organizing warp and many group parallels strands are knitted and formed more, often organizing described warp and include at least one first warp and at least one second warp, described first warp is elastic force bundle；Described second warp arranges reserved section between adjacent described parallel；(2) Gypsum Fibrosum is prepared into gypsum slurries；(3) gypsum slurries is coated in base fabric, dries, obtain plaster bandage.
Technique scheme, by arranging elastic force bundle, makes base fabric have certain elasticity, when tying up binder, reduces the requirement to elasticity, reduces the difficulty tying up binder, especially for new hand, improves efficiency.
Elastic force Shu Zuowei the first warp, provides elastic force for binder, and the second warp coordinates the first warp, controls again elastic force to a certain extent, makes the elastic force of binder a suitable scope, and fixed effect is better in use, and patient is more comfortable；Reasonable Arrangement between warp and parallel, the elastic force that binder is suitable can not only be ensured, elasticity can also be held do not bounce back, improve the firmness that binder is overall, between warp and parallel, form grid, hold Gypsum Fibrosum, the setting of elastic force bundle so that the size of grid has elasticity, the parcel power of Gypsum Fibrosum is better, Gypsum Fibrosum is not easy layering, it is ensured that fixed effect.
The base fabric of above-mentioned braiding, it is possible to be compiled into any width, then be cut into the width of needs, elastic force Shu Buhui bounces back, and the integrity of base fabric is good, the method for braiding binder traditionally, the braiding of elastic force bundle is entered, it is impossible to reduce, elastic force bundle retraction after reduction, causing that base fabric is disintegrated, integrity is destroyed, it is impossible to be continuing with, so when producing, can only the width of production requirement, and need bound edge, production is restricted.Binder disclosed by the invention, it is possible to be produced as any width, reduces further according to needs, and motility is higher, and does not need bound edge, Simplified flowsheet when producing.
As preferably, in step (3), before coating gypsum slurries, first base fabric tension mechanism being opened to the elastic force draw direction horizontal stretch of described elastic force bundle.
Before coating, stretch base fabric, open the mesh of base fabric, gypsum slurries can not only be made to rapidly enter mesh, and be attached in base fabric；In use, after getting wet, base fabric is shunk, and now suitably can be shunk by mesh, Gypsum Fibrosum tightens up parcel, and Gypsum Fibrosum does not have layering, and fixed effect is better, in useful life, does not have lax.
As preferably, described base fabric is under the stretching action of tension mechanism, and the length after stretching is 2.5-3.6 times of described base fabric natural length, after stretching, it is coated with Gypsum Fibrosum, molding, in use, after being stained with water, base fabric is collapsible, after being stretched to 2.5-3.6 times, the coating efficiency of gypsum slurries is best, during contraction, can reach Gypsum Fibrosum desirably wrapped up effect, improve the fixed effect of binder.
And the level of stretch in this programme, when being coated with gypsum slurries, the amount of gypsum of needs can be rapidly achieved, it is easy to control the hardening time of binder, the relaxation shrinkage appropriateness after immersion.
As preferably, described elastic force bundle includes the first stretch yarn and the second stretch yarn, described first stretch yarn is from passing below at described parallel, described second stretch yarn passing over from described parallel, described first stretch yarn crosses through with described second stretch yarn between adjacent described parallel above described second stretch yarn.
Arrange according to said structure, first, it is possible to the elastic force of the binder of guarantee；Secondly, the connection between elastic force bundle and parallel is more firm；Also ensuring that the service life of elastic force bundle, the elastic force obtaining binder is enough, firmness is enough, service life is enough.
As preferably, described second warp is provided with two, wherein described second warp passing over from described parallel, second warp passing below from described parallel described in another root, second warp described in another root two described second warps reserved section from described second warp cross over through, improve binder firmness.
As preferably, the length of described reserved section meets the described base fabric tensile elongation along elastic force bundle elastic force direction less than 4 times of described base fabric natural length.In this programme, maximum can reach naturalness length 4 times of the tensile elongation of base fabric, it is ensured that binder elastic force requirement in use, after the mesh that stretching is opened pours into Gypsum Fibrosum liquid, by retraction force, the parcel of Gypsum Fibrosum is good, during use, Gypsum Fibrosum is not stratified, and fixed effect is good.
As preferably, described parallel includes at least both threads yarn, coagulates and twists into one, improves the firmness of binder.
As preferably, described first stretch yarn and described second stretch yarn are coated with the wrap yarn of elastic filament in being, and use firmness good, and elastic filament is under the protection of wrap yarn, it is not easy to aging deformation.
By implementing technique scheme, the present invention has following beneficial effect:
1. technique is simple, provides certain elasticity for binder, and more convenient colligation, fixing better effects if, comfort level when patient uses is better；2. the parcel better effects if of pair Gypsum Fibrosum, during use, Gypsum Fibrosum does not have layering, it is ensured that fixed effect；3., by the reasonable setting through parallel, improve the entire firmness of binder；4. as required base fabric can be carried out cutting, after cutting, can guarantee that the globality of base fabric and firmness, not affect use, it is not necessary to bound edge, Simplified flowsheet.
