Description
Technical field
The present invention relates to a kind of dressing, particularly relate to a kind of bamboo protoconch polysaccharide functional dressing containing bamboo fibre, chitosan, belong to field of medical article technology.
Background technology
Injured or postoperative wound needs to be processed with dressing, to absorb the too much transudate transudate oozed out from wound, makes wound energy quickly-healing.But existing dressing comes with some shortcomings: when transudate is too much, water accepting layer can not sponge completely, can again go out from water accepting layer reverse osmosis, cause the impregnated maceration of the skin of wound, healing rate is slow, even occur festering, increase the misery of the wounded greatly, for this reason, the dressing of large quantities of improvement occurs successively, the Chinese patent being CN203662986 as the patent No. discloses a kind of novel foam composite wound dressing on June 25th, 2014, the lock water layer of the fast water accepting layer of water suction and strong lock water is set, ensure the temperature that wound is suitable, humidity, prevent the place's of sticking skin from occurring impregnation, wound healing is fast.But these dressing existing, if need to reach the effect accelerating healing, also need to coat medicine in the inner side of dressing, cumbersome, and the easy breed bacteria in wound, affect healing effect, even occur cross infection.
Summary of the invention
When the object of the invention is to solve existing dressing use, the easy breed bacteria of wound, healing effect is poor, and will use the defect of medicine, provides a kind of bamboo protoconch polysaccharide functional dressing, good permeability, can be effectively antibacterial, absorb the liquid that wound oozes out fast, keep the microenvironment of wound proper moisture, be beneficial to the healing of wound, can also quick-acting haemostatic powder.
The present invention adopts following technical scheme, to reach foregoing invention object, a kind of bamboo protoconch polysaccharide functional dressing, comprise dressing basic unit, the raw material of described dressing basic unit comprises the chitin fiber of 1-2 weight portion and the bamboo fibre of 3-7 weight portion, and described chitin fiber and bamboo fibre form the dressing basic unit of nonwoven fabric construct by acupuncture.
By implementing this technical scheme, the present invention:
1. chitosan has another name called chitosan, is the product after chitin sloughs certain acetyl group, the poly-2-deoxidation of formal name used at school-β-D glucose, there are very strong hygroscopicity, good breathability and biocompatibility, also there is the antibiotic property of wide spectrum, effectively can prevent wound infection, be beneficial to wound healing; And the biodegradation of chitosan energy, can not to environment.
2. because pure chitosan film dressing exists the shortcomings such as poor mechanical property, fragility are comparatively large, water-resistance is poor, in chitin fiber, crisscross acupuncture has bamboo fibre, the intensity of dressing can be strengthened, improve the quality of dressing, the main component of bamboo fibre is cellulose, hemicellulose and lignin simultaneously, physiological action can be participated in directly or indirectly, itself there is certain antibacterial, Fungicidal substance, possesses health care, and can 100% biodegradation, anti-microbial property and the degradability of dressing can be improved, safety and sanitation environmental protection.
3. chitosan is a kind of natural macromolecular material forming hydrogel, and can become gel after meeting water, affinity is good, has certain elasticity and rate of tension, is conducive to the attachment of dressing and patient skin, and patient comfort degree is high, and no side effects.
4. chitin fiber and bamboo fibre form the one nonwoven fabric construct without layering by acupuncture, and more firmly, intensity is high, more durable; And impulse-free robustness on limit.
5. crisscross intersection between chitin fiber and bamboo fibre, respective efficacy effect is more lasting, and traditional medicine spread upon on dressing inner surface then easily comes off or rubbed.
As preferably, the raw material of described dressing basic unit also comprises the viscose rayon of 2-5 weight portion.
Adding of viscose rayon, one can strengthen the bonding strength between chitin fiber and bamboo fibre, improves the firmness of dressing entirety; Two support strengths that can improve dressing; Three due to the cost of viscose rayon low, the production cost of dressing can be reduced.
As preferably, also comprise the subsides skin layers being arranged on described dressing basic unit lower surface, described subsides skin layers is antiseepage rete.Antiseepage rete prevents the wound fluid by dressing siphons away from flowing back to wound again, ensures the humidity that wound is suitable, promotes wound healing.
As preferably, described antiseepage rete is polymer membrane layer.
Described polymer membrane is polyphenyl alkene class or polyethylene kind or polyurethanes film.
As preferably, the chitosan of the chitosan of described chitin fiber to be deacetylation be 80-95%.The gel characteristic of deacetylation and chitosan is closely related, deacetylation is higher, during chitosan is more soluble in water, its gel characteristic is more obvious, and the deacetylation of 80-95% makes the rate of tension appropriateness of dressing, the intensity of certain dressing needs can be kept, have again certain pliability, be convenient to stick, deacetylation is too high, not only its suppleness is improper, and cost increases greatly.
As preferably, described chitosan is high-viscosity chitosan, and the viscosity of described high-viscosity chitosan is 0.8 ~ 1.0Pas.Be beneficial to the toughness maintaining dressing and the connection strengthened between chitin fiber and bamboo fibre.
As preferably, the weight of described dressing basic unit is 60-180g/m
2.Make the thickness of dressing suitable, good permeability, abundant wound fluid can be absorbed again.
As preferably, the lock water layer of described dressing basic unit upper surface, described lock water layer is strong water-absorption fiber layer.The capillary force of lock water layer is greater than the capillary force of dressing basic unit.
Transudate is sucked by hydrophilic group by lock water layer by systemic for dressing basic unit wound fluid, after sucking, the rapid swelling of lock water layer material, forms the water gel of some strength, has good lock outlet capacity, even if having certain pressure effect on it, water also not easily backflows and oozes out.
The present invention is beneficial to above-mentioned technical scheme, and the beneficial effect reached is as follows:
1. accelerating wound:
1) ensure the epidemic disaster that wound is suitable: adopt and have strong hygroscopic dressing basic unit, siphon away wound fluid in time, keep being beneficial to wound healing microenvironment, and be provided with antiseepage film, transudate can not reflux, and remains on lock water layer; The dressing of suitable thickness can also keep the temperature that wound is suitable, is beneficial to wound healing;
2) there is good antibacterial, bactericidal action: adopt and there is the antibacterial chitin fiber of sterilization and bamboo fibre, can play to wound the antibacterial action that effectively sterilizes, avoid wound infection, accelerating wound.
2. dressing is firm: adopt bamboo fibre and the viscose rayon with certain holding strength, and intertexture crisscross with chitin fiber, acupuncture molding, not stratified, greatly strengthen firmness and the intensity of dressing entirety.
3. use comfortable: chitosan is a kind of natural macromolecular material forming hydrogel, can become gel after meeting water, affinity is good, has certain elasticity and rate of tension, is conducive to the attachment of dressing and patient skin, and patient comfort degree is high.
4. have no side effect, environmentally safe: dressing is not with medicine, is beneficial to the characteristic of base material itself, accelerates the healing of wound, and drug action is lasting, has no side effect; And base material is all biodegradable, environmentally safe.
