Description
Technical field
This utility model relates to medical dressing technical field, specifically comprises a kind of compoundly to protect wound dressing.
Background technology
Skin is the vitals of human body, it play control body temperature, protect from infection, immunity and sensing effect.Due to reasons such as wound, scratch, skin ulceration and burns, the large range damage of skin may be caused.Skin damage easily causes bacteriological infection after doing harm to, body fluid runs off and leads to complications.Usually adopt wound dressing to carry out sure catch to wound in prior art, the moist environment of the wound that absorbs sepage, prevents wound infection, maintains also promotes wound healing.And have following requirement for wound dressing: 1. nontoxic, harmless, non-stimulated.2. can stop antibacterial, form the good environment of an applicable tissue growth.3. there is the suitable for ability of gas and steam.4. the temperature and humidity of wound facing face can be kept.5. isolation and the conduction of heat can be provided.6. excellent adsorption, can control and breathe exudate.7. easy to use, tear off easily adhesion skin.8. have good mechanical performance, flexibility is suitable with human body skin, also can keep certain form and intensity time moistening.
At present, market is that the gauze made with various fiber or non-woven fabrics are formed by stacking for wrapping up the medical dressing of health wound surface mostly.Medical dressing, except being isolated from the outside by wound surface, for the protection of except wound surface, also requiring that dressing has very strong imbibition ability, can draw the liquid that wound surface oozes out, and makes wound surface keep moistening, reduces the risk of traumatic infection and wound healing.But there is following defect in these dressing existing:
(1) adhesion wound surface: because liquid-adsorption layer directly contacts with wound surface, and liquid-adsorption layer is made mainly with various fiber, is easy to wound tissue bonding.
(2) liquid absorption is not enough: liquid absorption is generally 12 g/g, is unsuitable for the nursing of large wound surface.
(3) without antibacterial, fungistatic effect or weak effect: with various gauze or non-woven fabrics as liquid-adsorption layer, absorb the overflow of wound surface and bleed back to wound surface, cause the easy breed bacteria of wound surface and cause wound infection.
The dressing function for wound care used clinically is too single.The dressing such as traditional cotton spinning, gauze are the theoretical lower generations of wound dryness healing in the past, along with the proposition of wet union theory, its correctness is proved from different perspectives, the new dressing being substrate with materials such as chitosan, alginate, NACFs arises at the historic moment, but majority is by they single uses at present, its limitation is more and more outstanding, as NACF dressing is not suitable for infected wound care, and chitosan dressing is not suitable for oozing out the large wound nursing of liquid measure.Therefore, the hope of seeking a kind of dressing of multi-functional, applicable various wound care is more and more urgent.The function of dressing is extended and is necessary, the function of extension mainly contains anti, increases liquid absorption, hemostasis, antibacterial, antiinflammatory etc.If add on ventilative, absorbent function the bonding protective layer of protection wound surface and antibacterial, hemostasis, antiinflammatory protect wound layer; the suitability of this dressing just increases a lot; that is: not only can be used for infected wound but also can be used for non-infected wound; there is facilitation to the healing of wound, and alleviate the misery of patient.
Utility model content
This utility model is the defect overcoming above-mentioned prior art, provides a kind of multi-functional anti, the efficiently compound of imbibition and broad-spectrum antibacterial function to protect wound dressing.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

Further, described liquid-adsorption layer is combined by pressure sensitive adhesive with adhered layer, described liquid-adsorption layer with protect the soft tissue medical adhesive tight bond created layer and formed by medical alpha-cyanopropyl acid esters system's glue and fibrin biotype glue.
Preferably, the thickness of described protective layer is 0.05 ~ 0.2mm.
Further, described liquid-adsorption layer is NACF, cotton adsorptive pads, non-woven fabrics adsorptive pads, acrylic resin and water suction foam.
Preferably, described liquid-adsorption layer is NACF, and NACF is the NACF comprising the series such as viscose glue base, asphaltic base, PAN base, natural plant fibre base.
Further, it is chitin fiber, alginate fibre that layer is created in described protecting, and at least one fiber is formed by weaving through non-woven fabrics craft.
It is preferably, described that to protect wound layer be the non-woven fabrics that chitin fiber and alginate fibre are weaved with the ratio of 1:1.
Preferably, it is 0.1-0.5 mm that layer thickness is created in described protecting, and it is 60-110 g/m that layer grammes per square metre is created in described protecting
2.
Preferably, described adhered layer is pressure sensitive adhesive non-woven fabrics, described adhered layer grammes per square metre 50-100 g/m
2.
Preferably, described peel ply is Ge Laxin silicone oil paper, and described peel ply grammes per square metre is 40-90 g/m
