Description of drawings
Fig. 1 is the structural representation of a kind of functional type polyurethane foam medical dressing A in the embodiment of the present application 1;
Fig. 2 is the structural representation of a kind of functional type polyurethane foam medical dressing B in the embodiment of the present application 2.
The specific embodiment
Also by reference to the accompanying drawings the application is described in further detail below by specific embodiment.Below explanation should not be construed as the restriction to the application.
Embodiment 1
Please refer to Fig. 1, the structural representation of a kind of functional type polyurethane foam medical dressing A that Fig. 1 provides for this utility model, it comprises auxiliary layer 1 and polyurethane flexible foam body 2, both fit tightly as shown in the figure.
Auxiliary layer 1 is medicine layer, can be wound the active ingredient that helps heal is provided, and specifically can be the medicine layer of haemostatic medicament layer or other promotion wound healings.Auxiliary layer 1 directly overlays on the wound during use.By adopting the dressing of this structure, the active ingredient during use in its auxiliary layer 1 can fully be absorbed by wound, promotes the healing of wound.During this dressing of manufacture A, medicine can be made its one side that is attached to polyurethane flexible foam body 2 by modes such as sprayings, form auxiliary layer 1.
Wound fluid then is absorbed in the microcellular structure that enters polyurethane flexible foam body 1, then through capillary tension to external diffusion, volatilize at last in the entered environment, this moisture absorption mechanism has enlarged the ability of unit are dressing from wound surface eliminating liquid, makes it have long service life.Because its polyurethane flexible foam body has above-mentioned good transudate disposal ability, and wettability power is extremely strong, can reduce the replacing number of times, shorten wound healing time, alleviate simultaneously the patient suffering.On the other hand, because the polyurethane flexible foam body has good physical property, for example flexibility and elasticity, its flexibility can make its wound surface of well applying ointment or plaster, and reduces sense of discomfort and the pain of wound.And the high resiliency that it has, the various positions that are difficult to cover on human body so that it is convenient to apply ointment or plaster.On the whole, the Compressive Performance that the polyurethane flexible foam body is good can reduce the impact of wound on orthobiosis effectively.The thickness of polyurethane flexible foam body, size and shape, those skilled in the art can design according to concrete practical situation.
As shown in Figure 1, the edge thickness of the polyurethane flexible foam body 2 in this example is less than the centre, and is concrete, and the mind-set edge direction is successively decreased gradually in the edge thickness edge of polyurethane flexible foam body.The purpose of design is like this, and during actual this dressing of use, dressing can use adhesive tape or other medical material that dressing further is fixed on the wound after wound is had good positioning.Because the polyurethane flexible foam body has certain thickness, when adhesive tape etc. fixedly during dressing, easily because the thickness of polyurethane flexible foam body, so that adhesive tape etc. form a untight space in the edge of polyurethane flexible foam body.The thickness of polyurethane flexible foam body is depended in the formation in this space, and its thickness is larger, and the space of formation is larger.Because the immobilization materials such as adhesive tape not necessarily have the functions such as fungi-proofing, this space is easy to form the Potential passageway that antibacterial enters wound surface, thereby has affected the healing of wound surface, may cause the deterioration of wound when serious.On the other hand, this space also is the potential threat that forms the transudate side leakage.Therefore, the mind-set edge direction is successively decreased the edge thickness of polyurethane flexible foam body gradually in the edge, can so that the thickness of polyurethane flexible foam body present sloping shape in edge, make its edge better and the perfect applying such as skin and adhesive tape, and can not produce the space of being caused by difference in height.
