Abstract
The utility model relates to a full degradation medical dressing piece, which comprises an isolation layer, an antiblocking layer, an effusion-absorbing layer and a water-proof and oxygen-resistant lining layer, a microcapsule with pressure-sensitive adhesives is arranged between the isolation layer and the lining layer, the isolation layer, antiblocking layer and lining layer is separately formed by a degradable carbon dioxide copolymer. The antiblocking layer contains biodegradable carbon dioxide copolymer that can prevent sticking with the wound. The utility model is applicable to surgical operation or trauma wound care, wherein the pressure-sensitive glue acts as a glue band, which brings very large conveniences to a medical staff and a patient. The materials are degradable so as to avoid white pollution and iatrogenic pollution, while the materials have a better oxygen-resistance, which is favorable to healing of the wounds.
Description
Technical field
This utility model relates to the medical dressing product, specifically a kind of full degradation-type medical dressing sheet.
Background technology
Current medical dressing sheet must rely on adhesive tape (as zinc oxide adhesive plaster) to be attached on the skin, the inconvenience part is arranged in the use, and be to receive wound fluid while and wound surface to stick together mostly, cause damage new granulation tissue when removing, and delay wound healing.The dressing that has in addition is back lining materials with polyolefine material such as polyethylene film, polypropylene film, because the non-degradable of these back lining materials causes white pollution and iatrogenic pollution.
Summary of the invention
Technical problem to be solved in the utility model is in order to overcome the deficiency of above-mentioned technology, and a kind of full degradation-type medical dressing sheet of easy to use, simple in structure, good environmental protection is provided.
The technical scheme in the invention for solving the above technical problem is: a kind of full degradation-type medical dressing sheet, it is by sealing coat, antiblocking layers, receives and ooze out the composite sheet that liquid layer and waterproof, resistance oxygen backing layer constitute, it is characterized in that: be provided with the microcapsule that has pressure-sensitive adhesive all around between sealing coat and the backing layer, sealing coat, antiblocking layers, backing layer are made of degradable carbon dioxide copolymer respectively.
This utility model is used for surgical operation or traumatic surface nursing, similar before using with common dressing sheet, but in use, be attached on the wound surface, dressing sheet periphery is exerted pressure, and be dispersed in that microcapsules rupture overflows in the dressing sheet frame this moment, and pressure sensitive adhesive wherein plays the effect of adhesive tape, it gives medical personnel and patient's use, brings great convenience; The degradability of its materials used has been avoided white pollution and iatrogenic pollution; The oxygen resistance that it is good can also promote the healing of wound surface.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is this utility model structural representation
Number in the figure is: 1. sealing coat, 2. antiblocking layers 3. receives and oozes out liquid layer, 4. backing layer, 5. microcapsule.
The specific embodiment
As shown in Figure 1, this utility model is a kind of full degradation-type medical dressing sheet, and it is by sealing coat 1, antiblocking layers 2, receives and ooze out liquid layer 3 and waterproof, resistance oxygen backing layer 4 constitute; Be provided with the microcapsule 5 that has pressure-sensitive adhesive all around between sealing coat 1 and the backing layer 4, sealing coat 1, antiblocking layers 2, backing layer 4 are made of degradable carbon dioxide copolymer respectively.Its each constitute layer and all can degrade, particularly antiblocking layers 2 constitutes for having the carbon dioxide copolymer that prevents with the biocompatibility of wound adhesion.
Sealing coat 1 of the present utility model plays and prevents the contaminated or damage in dressing sheet surface before use.Antiblocking layers 2 is owing to have good biocompatibility, and when directly contacting with wound surface, the adhesion of dressing sheet and wound surface causes when removing, the impaired and influence healing of wound surface new granulation tissue.Receive and ooze out liquid layer 3 and receive the Wholly-degradable material of exudate to form by having high multiple, it can be adsorbed on wound fluid between the material internal molecule, does not have transudate to exist on the surface, has avoided the generation of the traumatic infection that causes owing to bacterial growth.Backing layer 4 plays a part waterproof, oxygen barrier, and the immersion of on the one hand anti-sealing reduces traumatic infection generation probability; On the other hand, intercept the infiltration of aerial oxygen, make the granulation tissue of wound surface be in the condition that no aerial oxygen exists, promoted the healing of wound surface.
This utility model and existing dressing sheet difference are that also it has the microcapsule 5 of potential pressure sensitive adhesive all around, the performance that the dressing sheet is not pasted skin before using, and it is attached on the wound surface when using this utility model, when exert pressure in dressing sheet edge, being dispersed in dressing sheet periphery attaches the capsule pressurized of frame and breaks, make simultaneously that medical pressure-sensitive adhesive overflows in the sacculus, and the dressing sheet tightly is attached on the wound surface.
This utility model is simple in structure, and is easy to use, because its composition material can both biodegradation, so have the feature of environmental protection preferably, avoided " white pollution " and iatrogenic polluter; It has higher resistance oxygen again, helps site of injury and gets well.
Claims (2)
1. full degradation-type medical dressing sheet, it is by sealing coat, antiblocking layers, receives and ooze out the composite sheet that liquid layer and waterproof, resistance oxygen backing layer constitute, it is characterized in that: be provided with the microcapsule that has pressure-sensitive adhesive all around between sealing coat and the backing layer, sealing coat, antiblocking layers, backing layer are made of degradable carbon dioxide copolymer respectively.
2. full degradation-type medical dressing sheet according to claim 1, it is characterized in that: antiblocking layers is the carbon dioxide copolymer with biocompatibility.
