Abstract
The utility model relates to a medical dressing field, concretely a novel medical PU membrane dressing of anti-adhesion even. A novel anti-adhesion medical PU film dressing comprises a topmost protective paper layer, a PU film layer is arranged on the lower portion of the protective paper layer, a medicinal cotton layer is arranged in the middle of the PU film layer, transverse absorption lines extending outwards are arranged on two sides of the medicinal cotton layer, a plurality of longitudinal absorption lines are arranged on two sides of the medicinal cotton layer at intervals, the transverse absorption lines and the longitudinal absorption lines are arranged in a staggered mode, and the medicinal cotton layer, the transverse absorption lines and the longitudinal absorption lines are all fixed on the PU film layer; the lower part of the PU film layer is provided with a fixed paper layer. The PU film dressing can effectively prevent the dressing from being adhered to the skin, and can effectively improve the absorption capacity to seepage.
Description
Technical Field
The utility model relates to a medical dressing field, concretely a novel medical PU membrane dressing of anti-adhesion even.
Background
The medical dressings are various, such as sterile gauze, sterile non-woven fabrics, common pressure-sensitive adhesive film dressing and the like, and can be used for different wounds, but the dressings have the defect of adhesion after being contacted with the wounds in the using process. New types of dressings are therefore emerging, such as gel-type dressings, but the range of applications is yet to be expanded. Compared with an adhesive tape and a disinfection gauze, the polyurethane film dressing has great improvement, but after being used for a long time, the polyurethane film dressing is closely attached to the skin, so that the polyurethane film dressing has great difficulty in tearing off the skin, and the skin is easily damaged.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome not enough among the prior art, provide a novel medical PU membrane dressing of preventing adhesion even, this kind of PU membrane dressing can effectually prevent the adhesion even of dressing and skin to can effectively improve the absorptive capacity to the sepage.
In order to solve the prior art problem, the utility model discloses a novel anti-adhesion medical PU film dressing, which comprises a topmost protective paper layer, a PU film layer is arranged at the lower part of the protective paper layer, a medicinal cotton layer is arranged at the middle part of the PU film layer, and transverse absorption lines extending outwards are arranged at two sides of the medicinal cotton layer, and are longitudinal absorption lines arranged at a plurality of intervals at two sides of the medicinal cotton layer, the transverse absorption lines and the longitudinal absorption lines are arranged in a staggered way, and the medicinal cotton layer, the transverse absorption lines and the longitudinal absorption lines are all fixed on the PU film layer; the lower part of the PU film layer is provided with a fixed paper layer.
Preferably, the length of the transverse absorption line is smaller than the length of the PU film layer.
Preferably, the length of the longitudinal absorption line is smaller than the width of the PU film layer.
Preferably, the protective paper layer and the fixed paper layer are both made of release paper.
Preferably, the transverse and longitudinal absorption lines are made of cotton or sterile cotton.
The utility model has the advantages that: the lower part of the PU film layer is provided with the longitudinal absorption lines and the transverse absorption lines which are arranged in a staggered mode, so that fluctuation is added in the flat PU film, a certain gap is formed between the PU film layer and the skin after the PU film layer is attached to the skin, the attachment area is reduced, and the PU film layer is easy to remove. It is clear that the arrangement of transverse and longitudinal absorption lines should not be too dense or do not give good adhesion. The longitudinal absorption lines and the transverse absorption lines are connected with the absorbent cotton layer, the absorbent cotton layer is placed at the position of a wound, and when seepage seeps out of the wound, the absorbent cotton layer can be absorbed through the longitudinal absorption lines and the transverse absorption lines, so that the situation that the absorbent cotton layer cannot be led out nearby the wound all the time and the wound healing is influenced is avoided.

Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
A novel anti-adhesion medical PU film dressing comprises a topmost protective paper layer 1, a PU film layer 2 is arranged on the lower portion of the protective paper layer 1, a medicinal cotton layer 3 is arranged in the middle of the PU film layer 2, transverse absorption lines 4 extending outwards are arranged on two sides of the medicinal cotton layer 3, a plurality of longitudinal absorption lines 5 arranged at intervals are further arranged on two sides of the medicinal cotton layer 3, the transverse absorption lines 4 and the longitudinal absorption lines 5 are arranged in a staggered mode, and the medicinal cotton layer 3, the transverse absorption lines 4 and the longitudinal absorption lines 5 are all fixed on the PU film layer 2; the lower part of the PU film layer 2 is provided with a fixed paper layer 6.
The length of horizontal absorption line 4 is less than PU rete 2's length, the length of vertical absorption line 5 is less than PU rete 2's width, protective paper layer 1 all adopts from type paper with fixed paper layer 6, horizontal absorption line 4 and vertical absorption line 5 adopt cotton thread or aseptic cotton to make.
The utility model has the advantages that: the lower part of the PU film layer 2 is provided with the longitudinal absorption lines 5 and the transverse absorption lines 4, the longitudinal absorption lines 5 and the transverse absorption lines 4 are arranged in a staggered manner, some fluctuation is added in the flat PU film, a certain gap is formed between the flat PU film and the skin after the flat PU film is attached to the skin, the attachment area is reduced, and the removal is easy. It is clear that the arrangement of transverse absorption lines 4 and longitudinal absorption lines 5 should not be too dense or do not provide a good adhesion. The longitudinal absorption lines 5 and the transverse absorption lines 4 are connected with the absorbent cotton layer 3, the absorbent cotton layer 3 is arranged at the position of a wound, and when seepage seeps out of the wound, the seepage can be absorbed by the longitudinal absorption lines 5 and the transverse absorption lines 4, so that the phenomenon that the seepage can not be led out nearby the wound all the time and the wound healing is influenced is avoided.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
