Description

A kind of antibacterial adsorbs Wound dressing

Technical field

The utility model is related to a kind of Wound dressing, specifically a kind of antibacterial absorption Wound dressing.

Background technology

The reasons such as the rotten and bacterium infection due to surface of a wound skin histology, all wounds can produce one to varying degrees Fixed stink.For a long time, stink produced on wound causes very big inconvenience to patient and nursing staff.Some patients It is difficult normally to be worked and lived due to the stench on wound.The approach for clinically solving wound stink has two kinds, one It is to control the bacterium on wound to plant, and suppresses the breeding of bacterium, is inherently eliminated the generation of stink.Another kind is with suitable suction Enclosure material is odor absorption.Clinically using antibiotic method control bacterium at present more, but the extensive use of antibiotic makes wound The distribution of mouthfeel microbiological contamination and drug resistance also occur to change constantly, cause the generation of many refractory wounds and antibody-resistant bacterium Occur, researcher wishes to set about from Wound dressing solve this problem.

Utility model content

The purpose of this utility model is to provide a kind of antibacterial absorption Wound dressing, to solve wound infection peculiar smell and refractory ask Topic.

What the purpose of this utility model was realized in：

A kind of antibacterial adsorbs Wound dressing, includes one layer of water suction cushion layer and is attached at the of the water suction cushion layer upper surface One prevents adhesion film layer, and the water suction cushion layer is that have one layer of PHMB antibiotic layer in the carbon fiber wire surface spraying of absorbing carbon fiber water cushion, Described first film layer that prevents adhesion is to be coated with one layer of PHMB antibiotic layer in the outer surface of Plastic net film.

Described antibacterial absorption Wound dressing, is pasted with second and prevents adhesion film layer, institute in the lower surface of the water suction cushion layer It is to be coated with one layer of PHMB antibiotic layer in the outer surface of Plastic net film to state second film layer that prevents adhesion.

Described antibacterial absorption Wound dressing, one layer of base membrane layer, the base are pasted with the lower surface of the water suction cushion layer The edge of film layer is beyond the edge of the water suction cushion layer；Off-style paper layer is pasted with first upper surface for preventing adhesion film layer, The edge of the off-style paper layer is beyond the described first edge for preventing adhesion film layer；The base membrane layer exceeds the water suction cushion layer edge Part and the off-style paper layer beyond described first prevent adhesion film layer edge part it is bonded to each other.

Described antibacterial absorption Wound dressing, the first release liners that the off-style paper layer is overlapped by subregion and second from Type paper is constituted.

Described antibacterial absorption Wound dressing, the base membrane layer is the semipermeability transparent polyurethane for being coated with pressure-sensitive adhesive layer Film or non-woven fabrics.

With carbon fiber dressing be combined together PHMB by the utility model, prepares novel antibacterial carbon fiber dressing, overcomes The drawbacks of being also easy to produce antibody-resistant bacterium of antibiotic dressing, has the antibacterial activity of PAN-ACF characteristic and PHMB, preparation side concurrently Method is simple and easy to apply, and raw material is easy to get, with low cost, the problems such as solve the drug resistance containing antibiotic dressing.

Specific embodiment

Embodiment 1

（1）Prepare PHMB solution：2g hexamethylenes, plus purified water are taken to 1000ml, is stirred after dissolving Uniformly, obtain final product.

（2）Spray PHMB：Absorbing carbon fiber water cushion coiled material is placed in and is unreeled on roll shaft, unreeled with the speed of 1m/min, this mistake Cheng Zhong, spray equipment sprays PHMB solution with the speed of 2.0mL/s to adsorptive pads coiled material, while wind-up roll shaft 2 is with 1m/min's Speed winds, and so repeats 3-4 times, PHMB solution is uniformly sprayed onto the carbon fiber wire surface of carbon fiber coiled material.

（3）Dry：The absorbing carbon fiber water cushion coiled material for finishing will be sprayed, using mesh-belt type drier, control temperature is not higher than 50 DEG C are done dried process.

（4）Cross cutting, shaping：By dried absorbing carbon fiber water cushion coiled material, directly cut with dressing forming machine in blocks.

（5）As shown in figure 1, first is prevented adhesion film layer（It is coated with the Plastic net film 2 of PHMB antibiotic layers 1）It is pasted to carbon fine Dimension adsorptive pads（That is water suction cushion layer 3）Upper surface, form the dressing of structure as shown in Figure 1, or as shown in Fig. 2 anti-sticking by first Even film layer and second film layer that prevents adhesion are pasted to absorbing carbon fiber water cushion respectively（That is water suction cushion layer 3）Upper and lower surface, shape Into the dressing of structure as shown in Figure 2.

Embodiment 2

（2）Spray PHMB：Absorbing carbon fiber water cushion coiled material is placed on roll shaft 1, is unreeled with the speed of 1m/min, this process In, spray equipment sprays PHMB solution with the speed of 2.0ml/s to adsorptive pads coiled material, while roll shaft 2 is received with the speed of 1m/min Volume.So it is repeated 3 times, PHMB solution is uniformly sprayed onto carbon fiber coiled material as far as possible.

（3）Dry：The carbon fiber coiled material for finishing will be sprayed, using mesh-belt type drier, control temperature is not higher than 50 DEG C and does Dried process.

（4）Cross cutting, shaping：By dried absorbing carbon fiber water cushion coiled material, directly cut in flakes, then with dressing forming machine First is prevented adhesion film layer（It is coated with the Plastic net film 2 of PHMB antibiotic layers 1）It is pasted to absorbing carbon fiber water cushion（That is water suction cushion layer 3）Upper surface, then itself and release paper web and base material coiled material are formed such as in the last cross cutting of dressing forming machine, composite molding The dressing of structure shown in Fig. 3, the i.e. lower surface in water suction cushion layer 3 are pasted with one layer of base membrane layer 6, and base membrane layer 6 is pressure-sensitive to be coated with The semipermeability transparent polyurethane film or non-woven fabrics of glue-line, the edge of base membrane layer 6 is beyond the edge of water suction cushion layer 3；It is anti-first The upper surface of adhesion film layer is pasted with off-style paper layer, and the edge of off-style paper layer prevents adhesion the edge of film layer beyond first；Base membrane layer 6 Beyond the edge of water suction cushion layer 3 part and off-style paper layer beyond first prevent adhesion film layer edge part it is bonded to each other.Release liners The first release liners 4 and the second release liners 5 that layer is overlapped by subregion are constituted.

Release liners can be CCK paper, silicone oil paper；Base material can be the non-woven fabrics of spraying pressure sensitive adhesive, spray the poly- of pressure sensitive adhesive Urethane film.
