Description

A kind of wound dressing and preparation method thereof
Technical field
The present invention relates to a kind of dressing, especially a kind of wound dressing and preparation method.
Background technology
Currently based on the functional wound dressing of the high-absorbable energy of wet union theory research and development, such as alginate dressing, carboxylic The non-woven dressings such as methylcellulose dressing and chitosan dressing are widely used in acute and chronic wounds nursing.Wound dressing touches After wound fluid, soft gel can be formed, ideal moist environment is provided for wound healing.But after dressing use, When need to be removed from wound, due to the structure problem of non-woven fabrics itself, dressing is caused not remove integrally.Dressing is collapsed or is ruptured So that a part for dressing is likely to remain in wound and causes risk, it is necessary to irrigate.
Therefore, it is based on drawbacks described above, being badly in need of offer one kind in the market being capable of gelation after contacting human body wound fluid Wound dressing composition, and while removing after use can keep the wound dressing and preparation method of the integrality of dressing.
Invention content
Based on this, the invention reside in overcoming the deficiencies of existing technologies, one kind energy after contacting human body wound fluid is provided The wound dressing and system of the integrality of dressing can be kept when reaching the wound dressing composition of gelation, and removing after use Preparation Method.
Its technical solution is as follows:A kind of wound dressing, by contain gelatinous fibre, textile fabric, two kinds of thermoplastic fibre or Two or more fiber compositions, the gelatinous fibre content are 50% ~ 100%, and textile fabric content is 0% ~ 50%, and thermoplastic fibre contains Amount is 0% ~ 20%;The wound dressing grammes per square metre is 60 ~ 200g/cm2, and thickness is 0.5 ~ 5.0mm, and liquid absorption amount is not less than 10g/ 0.9% saline solution of 100cm2.
As advanced optimizing for above-mentioned technical proposal, the gelatinous fibre is sodium carboxymethyl cellulose fibre, chemistry changes Property cellulose fibre, pectin fiber, alginate fibre, chitin fiber, Hyaluronan fibers, polysaccharide fiber or gummy fiber One of which.
As advanced optimizing for above-mentioned technical proposal, the cellulose fibre is with every glucose unit at least 0.05 The degree of substitution of a carboxymethyl.
As advanced optimizing for above-mentioned technical proposal, the gelatinous fibre is with every gram of fiber at least 2 gram of 0.9% salt The absorbability of aqueous solution.
As advanced optimizing for above-mentioned technical proposal, the textile fabric is, tencel fiber, viscose rayon, nylon are fine The one of which of dimension, polyester fiber, nylon fibre, cotton fiber.
As advanced optimizing for above-mentioned technical proposal, the thermoplastic fibre is PE fibers, PP fibers, PET fiber, PS The one or more of which combination of fiber, ABS fibers, PE/PET fibers, PE/PP fibers.
A kind of preparation method of wound dressing comprising a kind of above-mentioned wound dressing, a kind of system of wound dressing Preparation Method includes the following steps:
S1, offer composite fibre in, gelatinous fibre content is 50% ~ 100%, and textile fabric content is that 0% ~ 50%, thermoplasticity is fine Dimension hplc is 0% ~ 20%, the gelatinous fibre, textile fabric and thermoplastic fibre is carried out blended;
S2, will be blended after wound dressing it is perverse into the hand-manipulating of needle, needle thorn after enter next step;
S3, wound dressing of the needle after perverse carry out to rolling and molding, temperature is not less than 110 DEG C when hot rolling.
Beneficial effects of the present invention are:The wound dressing is a kind of composition, and preparation method is simple, the wound dressing group Close after object contact human body wound fluid can gelation, and while removing after use can keep the integrality of dressing.
Specific implementation mode
A kind of wound dressing provided in an embodiment of the present invention, by containing gelatinous fibre, textile fabric, two kinds of thermoplastic fibre Or two or more fiber compositions, the gelatinous fibre content are 50% ~ 100%, textile fabric content is 0% ~ 50%, thermoplastic fibre Content is 0% ~ 20%;The wound dressing grammes per square metre is 60 ~ 200g/cm2, and thickness is 0.5 ~ 5.0mm, and liquid absorption amount is not less than 10g/ 0.9% saline solution of 100cm2.
In a kind of embodiment, the gelatinous fibre is sodium carboxymethyl cellulose fibre, chemically-modified cellulose fiber, pectin The one of which of fiber, alginate fibre, chitin fiber, Hyaluronan fibers, polysaccharide fiber or gummy fiber.
In a kind of embodiment, the cellulose fibre is the substitution at least 0.05 carboxymethyl of every glucose unit Degree.
In a kind of embodiment, the gelatinous fibre is the absorbability at least 2 gram 0.9% saline solution of every gram of fiber.
In a kind of embodiment, the textile fabric is, tencel fiber, viscose rayon, nylon fiber, polyester fiber, polyamide fibre The one of which of fiber, cotton fiber.
As advanced optimizing for above-mentioned technical proposal, the thermoplastic fibre is PE fibers, PP fibers, PET fiber, PS The one or more of which combination of fiber, ABS fibers, PE/PET fibers, PE/PP fibers.
A kind of preparation method of wound dressing comprising a kind of above-mentioned wound dressing, a kind of system of wound dressing Preparation Method includes the following steps:
S1, offer composite fibre in, gelatinous fibre content is 50% ~ 100%, and textile fabric content is that 0% ~ 50%, thermoplasticity is fine Dimension hplc is 0% ~ 20%, the gelatinous fibre, textile fabric and thermoplastic fibre is carried out blended;
S2, will be blended after wound dressing it is perverse into the hand-manipulating of needle, needle thorn after enter next step;
S3, wound dressing of the needle after perverse carry out to rolling and molding, temperature is not less than 110 DEG C when hot rolling.
The wound dressing is a kind of composition, and preparation method is simple, and wound dressing composition contact human body wound oozes Go out after liquid can gelation, and while removing after use can keep the integrality of dressing.
The present invention passes through certain proportion on the basis of existing technology, by gelatinous fibre, textile fabric and thermoplastic fibre Blended, needle thorn, hot rolling form the wound dressing with tridimensional network.Three component of dressing respectively has function, gelatinous fibre tool There is high liquid-absorbing energy, soft gel can be formed, ideal moist environment is provided for wound healing;Textile fabric can increase dressing Wet strength, improve wick effect;Space network is formed after thermoplastic fibre hot rolling, increases wet strength, is reduced fine Dimension is fallen.The wound dressing that this method is prepared is high with liquid absorption amount, fiber is fallen less, gel shrinks are few, wet strength is high, suitable Answering property is good, the advantages of can integrally removing.
The technique effect that the present invention is brought:Liquid absorption amount is high, fiber is fallen less, shrinkage rates are small, wet strength enhancing, complies with Property is good.
Several embodiments of the invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention Range.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
