Description

Scar paste easy to tear after being adhered to skin

Technical Field

The utility model relates to the technical field of medical supplies, especially, relate to a scar subsides that easily tear after gluing in skin.

Background

The scar is a local symptom which is caused by that the damage of physical, biological, chemical and other factors acts on skin soft tissue to cause serious damage of the skin soft tissue and cannot completely and normally recover, and the appearance is influenced and the function is influenced after the scar is replaced and repaired by fibrous tissue. At present, except for surgical scar removal, the use of a silica gel scar patch is the most effective, and the silica gel scar patch inhibits scar hyperplasia by applying scars on the surface of a wound and performing functions of pressure, shrinkage and the like. The attaching time of the scar paste is as long as 6-12 hours in the period of using the scar paste, the scar paste on the periphery of the silica gel paste is tightly adhered with the skin after being applied for a period of time due to large viscosity, and particularly for the scar which is not completely recovered after the operation, a patient cannot tear a wound with great force, so that the scar paste is torn off from the skin after each use, which is a very painful process, and even the scar paste is only torn off after being soaked by skin oil, water and the like. Particularly in summer with high temperature, the skin directly contacting with the scar plaster can generate a local erythema due to the air impermeability.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a paste scar that easily tears behind skin to it is difficult to paste the scar and tear smoothly from skin to use the scar to paste the back at every turn among the solution prior art, and paste direct contact's skin with the scar because the problem of ventilative meeting local exanthema, this scar pastes on the basis of guaranteeing better adhesion nature, glues and can easily tear behind skin, has the good gas permeability that is superior to ordinary scar subsides simultaneously.

In order to solve the problem, the utility model relates to a glue easily the scar subsides that tear behind skin and adopt following technical scheme:

the utility model provides a glue scar subsides that easily tear behind skin, includes upper and middle, lower three layer construction, and the upper strata is ventilative thin layer, and the middle level is the autohension silica gel layer, and the lower floor is for leaving the type protection film, the inner layer face on ventilative thin layer, except that the region of laminating mutually with the autohension silica gel layer has concave-convex structure, and wherein, concave-convex structure's convex surface is the adhesion surface that can laminate mutually with skin, and concave surface of concave-convex structure is the smooth surface, forms the bleeder vent with external intercommunication between smooth surface and the skin.

Furthermore, the concave-convex structure is a structure formed by uniformly arranging a plurality of strip-shaped bulges at intervals.

Further, the cross section of the strip-shaped protrusion is rectangular.

Furthermore, the edge of the strip-shaped raised self-adhesive silicon gel layer extends to the edge of the breathable film layer.

Furthermore, the middle part of the release protective film is provided with a wavy dividing line, and the separating protective film is split into two parts by the dividing line.

Further, the breathable film layer is a breathable polyurethane film layer or a silica gel film layer.

The utility model has the advantages as follows:

1. the utility model discloses a scar that easily tears after gluing on skin pastes, adopts the concave-convex structure design in the inner layer face of ventilative thin layer, except that the region of laminating with the autohension silica gel layer, the convex surface of concave-convex structure is the adhesion surface that can laminate with skin, can guarantee to have better adhesion with skin; and concave surface of concave-convex structure is the smooth surface for there is not sticky region between two adjacent adhesion faces, thereby makes this scar subsides can easily be torn after gluing in skin, avoids pasting the in-process skin that tears down with the scar and is excessively torn, alleviates painful sense.

2. Because the smooth surface is not contacted with the skin, a channel can be formed between the smooth surface and the skin, namely, an air hole communicated with the outside can be formed between the smooth surface and the skin, and the local skin covered by the scar plaster can be ventilated due to the air hole, so that the scar plaster has good air permeability which is superior to that of a common scar plaster, and the probability and the area of red rashes are reduced.

Detailed Description

In order to make the technical purpose, technical solution and advantageous effects of the present invention clearer, the technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

The utility model relates to a glue in the scar of easily tearing behind skin subsides embodiment, as shown in fig. 1-3, including upper, middle and lower three layer construction, the upper strata is ventilative thin layer 1, and the middle level is self-adhesive silica gel layer 2, and the lower floor is from type protection film 3. The self-adhesive silicone gel layer 2 is attached to the central position of the breathable film layer 1, and the central position of the breathable film layer 1 can slightly recess downwards to a certain depth, so that the self-adhesive silicone gel layer 2 is convenient to attach and fix. On the interior aspect of ventilative thin layer 1, except the region of laminating mutually with self-adhesive silica gel layer 2 have concave-convex structure, wherein, concave-convex structure's convex surface is the adhesion surface that can laminate mutually with skin, and concave-convex structure's concave surface is the smooth surface, forms the bleeder vent 5 with external intercommunication between smooth surface and the skin. The protruded adhesive surface can ensure that the breathable film layer and the skin have better adhesion; the concave smooth surface allows a non-stick region to be present between two adjacent adhesive surfaces, i.e. a region where the breathable film layer is not in contact with the skin. Because the smooth surface area that concave down is less to on the whole viscidity of the thin layer of not influencing, make this scar paste can easily be torn after gluing in skin, avoid pasting the in-process skin that tears down with the scar and excessively tear, alleviate painful sense. In addition, in the area, because the smooth surface is not contacted with the skin, the air holes 5 communicated with the outside are formed between the smooth surface and the skin, and the local skin covered by the scar plaster is ventilated due to the air holes 5, so that the scar plaster has good air permeability which is superior to that of the common scar plaster, and the probability and the area of occurrence of red rashes are reduced.

In this embodiment, as shown in fig. 1 and 3, the concave-convex structure is a structure formed by arranging a plurality of strip-shaped protrusions 4 at uniform intervals. The cross section of the strip-shaped protrusion 4 is rectangular. In order to ensure better air permeability, the strip-shaped bulges 4 extend from the edge of the silicon gel layer 2 to the edge of the air permeable film layer 1.

The middle part of the release protective film 3 is provided with a wavy dividing line 6, and the dividing line 6 divides the release protective film into two parts. When in use, the parting protective film 3 can be easily torn to two sides from the middle parting line 6.

Wherein, ventilative thin layer 1 is ventilative polyurethane film layer or silica gel film layer. Active substances and auxiliary materials are added into the self-adhesive silicone gel layer 2, and the scar plaster can be cut into a square shape, a circular shape, an oval shape or other shapes according to requirements.

Finally, it should be noted that: the above-mentioned embodiments are only used for illustrating but not limiting the technical solution of the present invention, and any equivalent replacement and modification or partial replacement which do not depart from the spirit and scope of the present invention should be covered within the protection scope of the claims of the present invention.
