Embodiment 1

[0037] like Figure 1-4 As shown in the figure, an anti-adhesion micro-negative pressure self-priming wound protection system includes a self-priming swelling dressing 1 located on the skin wound surface, a self-priming swelling dressing 1 covering the outer surface of the self-priming swelling dressing 1 and the peripheral skin of the self-priming swelling dressing 1. medical film 2,

[0038] The inner surface of the self-absorption expansion dressing 1 facing the skin wound is provided with a medical anti-adhesive isolation film 3 .

[0039] The self-priming intumescent dressing 1 has suction holes 11 running through its inner and outer surfaces, and the medical anti-adhesive isolation film 3 is provided with through holes 31. The suction holes 11 are matched.

[0040] The cross section of the suction hole 11 is in the shape of "~", and the cross section of the through hole 31 is in the shape of "~". or as in Figure 5-7 As shown, the cross section of the suction hole 11...

Embodiment 2

[0058] The difference from the first example is: Figure 8-9 As shown, both the inner surface of the self-absorbing expansion dressing 1 facing the skin wound surface and the outer surface facing the medical sticker 2 are provided with a medical anti-adhesive isolation film 3 .

[0059] The advantages of the present invention are: after the medical anti-adhesion isolation film made of PU material is arranged, the adhesion of the wound surface and the self-absorption expansion dressing can be prevented, and the liquid harmful substances entering the self-absorption expansion dressing can be prevented from infiltrating reversely to the wound surface, causing harmful substances to interact with the wound surface. The wound isolation function can greatly reduce the slight discomfort when the dry and compressed self-priming expansion dressing is just applied to the sensitive wound; the inner and outer surfaces of the self-priming expansion dressing 1 are provided with medical anti-a...

Abstract

The invention discloses an anti-adhesion micro-negative-pressure self-suction type wound protecting system which comprises a self-suction expansion dressing located on a skin wound surface and a medical pasting film covering the outer surface of the self-suction expansion dressing and the peripheral skin of the self-suction expansion dressing, and a medical anti-adhesion isolating film is arranged on the inner surface, facing the skin wound surface, of the self-suction expansion dressing. Or medical anti-sticking isolating membranes are arranged on the inner surface, facing the skin wound surface, of the self-absorption expansion dressing and the outer surface, facing the medical sticking membrane, of the self-absorption expansion dressing. The self-absorption expansion dressing has the advantages that adhesion between the self-absorption expansion dressing and a wound surface can be improved by the aid of the medical anti-adhesion isolating membrane, and liquid harmful substances entering the self-absorption expansion dressing can be prevented from reversely permeating onto the wound surface to isolate the harmful substances from the wound surface.

Description

technical field [0001] The invention relates to the technical field of medical materials, in particular to wound care technology. Background technique [0002] Medical dressings are widely used in wound care, especially negative pressure dressings because of their ability to automatically absorb harmful substances such as edema fluid exuded from the wound, reduce microcirculation obstacles, promote blood supply and cell proliferation, thereby speeding up the wound. Healing, and reducing the burden of nursing care and many other advantages, negative pressure dressings have been popular since their introduction. Although most of the dressings are made of PVA raw materials, its viscosity to the wound surface is much lower than that of other dressing materials, but the wound surface is extremely sensitive to external stimuli due to skin damage, and there will always be adhesion between the dressing and the wound surface. In addition, during wound care, after the dressing is att...
