Abstract
The utility model discloses a waterproof ventilative high absorptivity chitosan protects to create and pastes, include substrate face, waterproof ventilated membrane, water absorbent resin and leave type paper, the middle part gomphosis of substrate face has annular sucking disc, waterproof ventilated membrane passes through the inboard of the substrate face of hot melt adhesive bonding inside annular sucking disc, water absorbent resin's upper surface and the bonding of waterproof ventilated membrane, lower surface and chitosan fiber non -woven fabric bonding, from the bonding of type paper in chitosan fiber non -woven fabric and the contact surface of wound and the inboard of substrate face. This waterproof ventilative high absorptivity chitosan protects to create and pastes throws off from type paper when using, protect create paste the bottom surface the chitosan fiber non -woven fabric laminating on the wound, inside air is extruded to pressing ring shape sucking disc simultaneously, makes it laminating skin firmly, the formation space that blocks water, the micropore diameter is greater than the gas molecule diameter for several centesimal of hydrone diameter on the waterproof ventilated membrane, can realize fine ventilation function.
Description
Technical field
This utility model belongs to wound dressing technical field, is specifically related to a kind of waterproof and breathable high-absorbable chitosan wound dressing.
Background technology
In daily life, work and various disease surgery and unexpected injury, often there is skin injury in various degree.It is badly in need of when skin injury using dressing cover and protect wound surface to be provided with the environment beneficially healed.The protected wound surface of self-adhering type dressing that rises after progressively replacing tradition absorbent carbasus, absorb sepage and do not glue the features such as wound, extensively apply in clinic at present and use till today.But self-adhering type dressing still suffers from many shortcomings: imbibition ability is not strong, when medical absorbent pads absorbs saturated, somewhat presses medical absorbent pads, furthermore is exactly that waterproof performance is the best, and when meeting water, liquid infilters inside from substrate surface, causes wound infection.
Utility model content
The purpose of this utility model is to provide a kind of waterproof and breathable high-absorbable chitosan wound dressing, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model following technical scheme of offer: a kind of waterproof and breathable high-absorbable chitosan wound dressing, including substrate surface, waterproof ventilated membrane, water-absorbing resin and release paper, the middle part of described substrate surface is chimeric Ring like suction disc, described waterproof ventilated membrane is combined in the inner side of substrate surface within Ring like suction disc by melt viscosity, the upper surface of described water-absorbing resin bonds with waterproof ventilated membrane, lower surface bonds with chitosan fabric nonwoven cloth, and described release paper is bonded in chitosan fabric nonwoven cloth and the contact surface of wound and the inner side of substrate surface.
Technique effect of the present utility model and advantage: this waterproof and breathable high-absorbable chitosan wound dressing, throw off release paper in use, the chitosan fabric nonwoven cloth of wound dressing bottom surface is fitted on wound, press Ring like suction disc simultaneously, air within Ji Chu, be allowed to fit firmly skin, formation blocks water space, internal water-absorbing resin has absorptance from the hundreds of high absorbent function to thousand of times of water of heavy sensation of the body, and water retention property is excellent, hydrogel is become once imbibition, even if pressurization also is difficult to water to separate, liquid will not be oozed out from substrate surface, on waterproof ventilated membrane, micro-pore diameter is that more than one the percent of hydrone diameter is more than gas molecule diameter simultaneously, good airing function can be realized.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is schematic cross-section of the present utility model.
In figure: 1 substrate surface, 2 Ring like suction disc, 3 waterproof ventilated membranes, 4 chitosan fabric nonwoven cloths, 5 water-absorbing resins, 6 release paper.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
nullThis utility model provides a kind of waterproof and breathable high-absorbable chitosan wound dressing as shown in Figure 1-2，Including substrate surface 1、Waterproof ventilated membrane 3、Water-absorbing resin 5 and release paper 6，The middle part of described substrate surface 1 is chimeric Ring like suction disc 2，Described waterproof ventilated membrane 3 is combined in the inner side of substrate surface within Ring like suction disc 2 by melt viscosity，Described waterproof ventilated membrane 3 is by '-diphenylmethane diisocyanate、Toluene di-isocyanate(TDI) and macromolecular polyol、The TPU polymeric membrane of the common reactive polymeric of PUW waterproof ventilated membrane chain extender，The upper surface of described water-absorbing resin 5 bonds with waterproof ventilated membrane 3，Lower surface bonds with chitosan fabric nonwoven cloth 4，Described water-absorbing resin 5 is by starch grafted acrylate polymerization crosslinking composition granule and the resin of acrylamide and acrylic acid salt crosslinking copolymerization composition granule pressing，Described release paper 6 is bonded in chitosan fabric nonwoven cloth 4 and the contact surface of wound and the inner side of substrate surface 1.
Realize principle of work and power and using method: throw off release paper 6 in use, the chitosan fabric nonwoven cloth 4 of wound dressing bottom surface is fitted on wound, pressing Ring like suction disc 2 simultaneously, air within Ji Chu, be allowed to fit firmly skin, formation blocks water space, internal water-absorbing resin 5 has absorptance from the hundreds of high absorbent function to thousand of times of water of heavy sensation of the body, and water retention property is excellent, hydrogel is become once imbibition, even if pressurization also is difficult to water to separate, liquid will not be oozed out from substrate surface, on waterproof ventilated membrane 3, micro-pore diameter is that more than one the percent of hydrone diameter is more than gas molecule diameter simultaneously, good airing function can be realized.
Last it is noted that the foregoing is only preferred embodiment of the present utility model; it is not limited to this utility model; although this utility model being described in detail with reference to previous embodiment; for a person skilled in the art; technical scheme described in foregoing embodiments still can be modified by it; or wherein portion of techniques feature is carried out equivalent; all within spirit of the present utility model and principle; the any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
