Abstract
The utility model relates to a medical dressing. The dressing is characterized in that fiber fabric is used as a carrier of an adhesive layer; the middle position of the adhesive layer is compounded with an activated carbon fiber adsorption layer; both ends of the adsorption layer are provided with a protective film layer used for covering the layer and the adsorption layer by adhesion. The utility model has the advantages that the activated carbon fiber adsorption layer is deformed to be broken and to be ineffective quickly; the utility model is conveniently used.
Description
This utility model is a kind of medical dressing, especially relates to a kind of activated carbon fiber dressing.
Dressing commonly used such as Clinical Processing surgical wound, wound surface, burn, scald, skin ulcer and decubital ulcer has sterile gauze and is soaked with the sliver of medicine; and the dressing of common viscose glue base fiber etc.; the major function of this this dressing is protection or isolates various wounds; make it to avoid the infection of bacterial virus, the function that then has sterilizing concurrently that has.
A kind of pure natural has the activated carbon fiber medical dressing of good protection and treatment function in clinical practice to various wounds in recent years; the typical structure of its manufactured goods is that the activated carbon fiber adsorption layer is set on the breathability integument, and integument is actual to be hospital gauze.
Facts have proved that the main deficiency that the said structure mode exists shows, breathability integument tensile strength is low yielding, this will cause adsorption layer also to be out of shape thereupon even rupture, and often distortion or the fracture because of adsorption layer can not contact local wound with it, and therapeutic effect must be affected.Also since the activated carbon fiber that the sufficient breathability of integument causes adsorption layer by the moisture content in the direct absorbed air of this layer, dust, shortened effective acting time of adsorption layer relatively, this dressing of only establishing integument in addition uses also owes convenient.
This utility model is the deficiency that has the dressing of medicinal active carbon fiber now for overcoming, and a kind of a kind of activated carbon fiber dressing of avoiding activated carbon fiber adsorption layer distortion fracture and too fast inefficacy that proposes.
Above-mentioned purpose obtains by the following technical programs: be the adhesive linkage of carrier with the fabric, the middle part of its kiss-coating face is compounded with the activated carbon fiber adsorption layer, and the kiss-coating face at adhesive linkage two ends is bonded with the protective film that covers this layer and adsorption layer.
Said adsorption layer is active carbon fiber felt or fiber cloth cut-parts, the specific surface area 700-2500m of its activated carbon fiber
2/ g, iodine sorption value 800-1500mg/g, benzene adsorbance 20-55%, serge blue adsorptive value 120--250ml/g, filament diameter 11-18um, micro-pore diameter 17A °-21A °, micropore volume 0.25-0.64ml/g, pH value are 7, chloride content is 0, ash＜1.5%.
Said activated carbon fiber adsorption layer surface is provided with the breathability integument, and its coalition and adhesive linkage are separable singly to be put;
Said adhesive linkage, its kiss-coating face are provided with at interval no adhesive tape uniformly.
Below with embodiment and description of drawings this utility model thereof.
Accompanying drawing 1 embodiment 1 structural representation accompanying drawing 2 Figure 1A-A view accompanying drawing 3 embodiment 2 structure partial generalized section accompanying drawings 4 Fig. 3 A-A view accompanying drawings 5 embodiment 3 structure partial generalized sections
Fig. 1 .2 illustrated embodiment 1; be to be that the kiss-coating face middle part of the adhesive linkage 1 of carrier is compounded with activated carbon fiber adsorption layer 2 at fabric; the kiss-coating face at adhesive linkage two ends also is bonded with protective film 3; this rete can cover kiss-coating face and adsorption layer, in order to the protection adsorption layer and prevent any adhesion of adhesive linkage.
Fig. 3 .4 illustrated embodiment 2 is on activated carbon fiber adsorption layer 2 surfaces breathability integument 4 to be set, and its effect can further prevent adsorption layer distortion, fracture.Integument 4 adopts general hospital gauze to get final product.All the other structures of present embodiment are with embodiment 1.
Embodiment illustrated in fig. 53 is a kind of specific form of embodiment 2, and the adsorption layer 2 that promptly is provided with integument 4 separates singly with adhesive linkage 1 to be put, but its meaning is the adsorption layer that working (finishing) area is bigger, combines with adhesive linkage during use again.
The activated carbon fiber adsorption layer of the various embodiments described above can adopt active carbon fiber felt or activated carbon fiber cloth cut-parts, and the technical parameter of activated carbon fiber should satisfy following each point, specific surface area 700-2500m
2/ g, iodine sorption value 800-1500mg/g, benzene adsorbance 20-55%, serge blue adsorptive value 120-250ml/g, filament diameter 11-18um, micro-pore diameter 17A °-21A °, micropore volume 0.25-0.64m1/g, pH value are 7, chloride content is 0, ash＜1.5%.
The various embodiments described above can have plurality of specifications and size, so that selected according to different wound character dough-making powder are long-pending, but embodiment 1 is applicable to various skin ulcers, wound infection and decubital ulcer basically, embodiment 2 is applicable to various surgical wound, wound, and embodiment 3 is applicable to large-area burns, scald, electric burn and chemistry scald.When making the dressing of use-case 1,2, unpack and throw off protective film and can stick in wound surface, very easy to use.
Adhesive linkage 1 its carrier of the present utility model belongs to the fabric of breathability, but its longitude and latitude count is bigger on the one hand, one side is coated with bonding agent on the other hand, therefore its permeability is lower than the integument that general hospital gauze is made, but its tensile strength is better than hospital gauze greatly, can effectively avoid the distortion fracture of adsorption layer, and can alleviate adsorption layer, delay this dressing effect out-of-service time relatively by the absorption of this layer to water in air part and antibacterial etc.Adhesive linkage 1 its bonding agent of the present utility model also can evenly be coated with and be spaced strip (not shown), can improve permeability to satisfy special requirement.
In sum, the utlity model has and can avoid activated carbon fiber adsorption layer distortion fracture and too fast inefficacy, And remarkable advantage easy to use.
