Abstract

The utility model discloses a fiber product and a medical dressing. The fiber product comprises a fiber net, and gel forming fibers and functional fibers are mixed in the fiber net. The fiber product adopts a mode of mixing the functional fibers with the gel forming fibers, and functional components are introduced into the fiber product made of the gel forming fibers, thereby not only simplifying processes, improving production efficiency and reducing production cost, but also improving a mechanical structure of the traditional medical dressing, and enhancing the cure and protective performance of the medical dressing to wounds.

Description

A kind of fibre and medical dressing

Technical field

The utility model relates to medical field, relates in particular to a kind of fibre and medical dressing.

Background technology

Along with the theoretical development and application of moist wound healing, can become the wound dressing of aquogel to obtain extensive use in medical care.Wherein, much can become the fiber (being called for short into glue fiber) of aquogel to be made into wound dressing, the medical dressing of processing like one-tenth glue fibers such as alginic acid fibre, carboxymethyl cellulose fiber, hydroxyethyl cellulose, oxidized fibre cellulose fibers is by commercialization.Yet, though the medical dressing that tradition becomes glue fiber to process provides suitable wound healing moist environment, its functional deficiency, its effect is further improved.

At present; Engendered the technology of in the medical dressing that becomes glue fiber to process, introducing functional components on the market; Mainly comprise following three kinds of modes: first; The functional components layer is mutually compound with other layers and process functional dressing, as the wound contacting layer for have functional chitosan fiber layer, intermediate layer be the absorbent cores pad, outer be the wound dressing cover layer; Mode two is carried out modification when becoming the glue fiber spinning, for example when the alginic acid fibre spinning, sneak into the functional component CMC and spin and process functional fiber, and utilize this functional fiber to make medical dressing; Mode three makes into glue fiber or its aggregate possesses functional through ion-exchange treatment.

Yet, more than several kinds of modes exist unreasonable products structure, equipment requirements is high, specification requirement is high, quality control is complicated or problem such as cost height.

The utility model content

The technical problem underlying that the utility model will solve is that a kind of technology is simple and easy, production efficiency is high, rational in infrastructure fibre and medical dressing are provided.

For solving the problems of the technologies described above, the utility model provides a kind of fibre, comprises fiber web, is mixed into glue fiber and functional fiber in the said fiber web.

Preferably, said one-tenth glue fiber and functional fiber evenly mix.

Said functional fiber comprise chitosan fiber, collagenous fibres, soybean fiber, pupa albumen fiber, bamboo fibre, flax fibre, NACF or the functional fiber that becomes by their modifications at least a.

Said one-tenth glue fiber comprises at least a in alginic acid fibre, carboxymethyl cellulose fiber, hydroxyethyl cellulose, hydroxy propyl cellulose cellulose fiber, the oxidized fibre cellulose fiber.

In a kind of embodiment, said fibre is a non-weaving cloth.

In a kind of embodiment, said fibre is ribbon or fibre bundle.

The utility model has also been protected a kind of medical dressing, is processed by above-described fibre.

The beneficial effect of the utility model is: the utility model is through with functional fiber and the mode that becomes glue fiber to mix mutually; Functional components is introduced into the fibre that glue fiber is processed; Not only can simplify technology, enhance productivity and reduce production costs; And improved the mechanical structure of conventional medical dressing, strengthened its nursing and therapeutic action for wound.

Fig. 2 is fibre sheet or the non-weaving cloth schematic cross-section of a kind of embodiment of the utility model;

Fig. 3 processes the process schematic representation of non-weaving cloth, fibre sheet or fibre bundle for the utility model.

The specific embodiment

Combine accompanying drawing that the utility model is done further explain through the specific embodiment below.

The fibre of the utility model protection can be non-weaving cloth, fibre sheet or fibre bundle; Among the embodiment as depicted in figs. 1 and 2; Fibres such as non-weaving cloth, fibre sheet or fibre bundle all comprise fiber web, and for example non-weaving cloth becomes cloth by fiber web through acupuncture or water jet process, fibre sheet or fibre bundle by fiber web through drawing-off, cut apart and technology such as merging is processed; Be mixed into glue fiber 10 and functional fiber 20 in this fiber web; Preferably, become glue fiber 10 and functional fiber 20 in fiber web, evenly to mix in certain proportion, and tangle each other to become to compact or loose structure.

Particularly; Functional fiber 10 can be at least a in chitosan fiber, collagenous fibres, soybean fiber, pupa albumen fiber, bamboo fibre, flax fibre or the NACF; Also can comprise one or more these fibers are carried out the modification functional fiber that obtains after the modification, modification obtains for example PVP-I fibre treated cellulose fiber of functional fibre.Become glue fiber 10 to comprise at least a in alginic acid fibre, carboxymethyl cellulose fiber, hydroxyethyl cellulose, hydroxy propyl cellulose cellulose fiber, the oxidized fibre cellulose fiber.

The manufacturing technique of a kind of fibre of present embodiment is as shown in Figure 3, comprises following flow process:

At first will become glue fiber to mix and shredding, form loose uniform fibers amalgam with functional fiber;

Then fiber mixing body carding is obtained the uniform fibers net;

According to concrete needs, fiber web is laid to certain thickness obtains satisfactory fiber web then;

At last, become cloth technology to process non-weaving cloth through acupuncture, perhaps through drawing-off, cut apart and technology such as merging is processed fibre bundle or fibre sheet, also can prepare other fibres flexibly certainly.

Above embodiment is through with functional fiber and the mode that becomes glue fiber to mix mutually; Functional components is introduced into the fibre that glue fiber is processed; Compare with the mode of recited function property composition in the prior art, have the advantages that technology is simple and easy, quality control is prone to, production efficiency is high and cost is low.Wherein fibre bundle also can further be made into dressing such as Gauze, pad.

Medical dressing absorption wound sepage of processing or people are for after squirting; One-tenth glue fiber wherein forms gel; Its original function of functional fiber performance is protected wound and is treated; Functional fiber by the one-tenth gel space structure that depends on is provided, thereby play the effect that strengthens dressing strength and integrality.Become gel can give that functional fiber function composition slowly discharges, the effect of dauer effect.Therefore improved the mechanical structure of conventional medical dressing, strengthened it for the protection of wound and the effect of treatment.

Above content is the further explain that combines concrete embodiment that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
