Abstract
The utility model relates to an absorbable and degradable dressing for inhibiting scars, which consists of a silica gel layer, a first dressing layer, a second dressing layer, a sticking layer and a stripping layer; the first dressing layer and the second dressing layer are positioned on the same plane and uniformly cover the bottom of the silica gel layer; the adhesive layer, the first dressing layer and the second dressing layer may be completely covered by the release layer. The utility model has reasonable and novel structural design, on one hand, the hemostatic and bacteriostatic effects can be fully exerted mainly through the dressing layer in the wound healing stage, and the utility model is particularly suitable for nursing acute bleeding wounds; on the other hand, as the dressing layer is gradually degraded and absorbed, the wound surface is healed, so that the exposed silica gel layer plays a role in inhibiting scar hyperplasia. Therefore, the dressing can avoid the trouble that the common wound needs frequent dressing change and nursing, and effectively protect the wound surface, thereby being more beneficial to the healing of the wound and reducing the generation of scars.
Description
Technical Field
The utility model relates to a medical macromolecular material goods, concretely relates to restrain absorbable and degradable dressing of scar.
Background
In daily life, everyone is inevitably collided with the bed with a wound. The healing of wounds requires the care of different dressing choices depending on the type of wound. After the wound is healed, scars can be seriously left, and the appearance is affected. For people with scars, the scars can not only form scars after the wounds are healed, but also can be raised and even spread to the periphery, and the longer the scar is, the larger the scar is, the keloid is formed. Keloid scars are essentially abnormal growth of scar tissue cells, an uncontrolled growth.
At present, the methods for treating scars are various, and mainly comprise smearing scar paste, wearing elastic clothes, superficial radiotherapy, injection treatment, laser treatment, operation treatment and the like. Each of these methods has merits and demerits, and none of them can achieve perfect effects. And part of scars are red and purple, higher than normal skin, and extremely difficult to recover in a short time, which causes serious appearance and mental influence on patients.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the defects of the prior art in the aspect of scar inhibition and providing an absorbable and degradable dressing which has the function of scar hyperplasia inhibition and is particularly suitable for acute bleeding wounds.
In order to solve the above problem, the utility model adopts the following technical scheme:
an absorbable and degradable dressing for inhibiting scar comprises a silica gel layer, a first dressing layer, a second dressing layer, an adhesive layer and a stripping layer; the first dressing layer and the second dressing layer are positioned on the same plane and uniformly cover the bottom of the silica gel layer; the adhesive layer, the first dressing layer and the second dressing layer may be completely covered by the release layer.
Preferably, the first dressing layer is an absorbable hemostatic gauze.
Preferably, the second dressing layer is composed of absorbable medical films with tissue induction function and different degradation time, and a small amount of silver ions are uniformly loaded on the films.
Preferably, the absorbable medical membrane is made of one or two of absorbable polyurethane, absorbable polyester, absorbable polyether, absorbable polyamino acid, absorbable carboxymethyl chitosan and absorbable hemostatic gauze.
Preferably, the adhesive layer is a low-sensitization medical pressure-sensitive adhesive.
Preferably, the release layer is a glassine silicone oil paper.
The utility model discloses restrain scar hyperplasia and mechanism do: on one hand, absorbable medical membranes with tissue induction function and different degradation time are used as cell crawling support layers attached to wounds, cells crawl and grow slowly through the membrane support structure in the process of wound healing, degradation time of degradable materials is different, tissue absorption time is different, crawling growth of wound cells is uniform, and therefore a skin-like texture structure is formed, and generation of large scars is prevented. On the other hand, silicone gel can limit the loss of water on the skin surface and increase the hydration of the stratum corneum, and the gel membrane can release low molecular silicone oil, and the oxygen solubility of the silicone oil molecules is 10 times higher than that of blood plasma and saline, so that the stratum corneum containing water has higher permeability to oxygen, oxygen can freely enter the skin surface, and the oxygen partial pressure on the epidermis and the dermis is increased. Hypoxia produces angiogenic signals that stimulate tissue growth, and elevated oxygen partial pressure can turn off such stimulation and signal scar growth to inhibit scar growth.
The utility model discloses following beneficial effect has: 1) the two layers of dressings can act on the wound at the same time, so that the hemostatic and bacteriostatic effects of the dressings are fully exerted, the wound is effectively nursed, the bleeding is stopped in time, the excessive blood loss is avoided, and the wound is effectively protected from infection; 2) the dressing layer can play double roles of effectively nursing wounds and inhibiting scar growth; 3) the nursing of the wound and the function of inhibiting scar hyperplasia are combined together, so that the adverse effect of frequent replacement of nursing dressing on wound healing is avoided; 4) the dressing layer is made of absorbable material, the wound is gradually healed along with the gradual absorption of the dressing layer by the metabolism of the human body, and after the dressing layer is completely absorbed and the wound is healed, the silica gel layer can fully exert the hydration function of the dressing layer, so that the dressing layer and the absorbable medical dressing film with different degradation times and tissue induction functions act together, the growth of scars is greatly limited, and the scar hyperplasia can be well resisted.

Description of reference numerals: 1. a silica gel layer, 2, a first dressing layer, 3, a second dressing layer, 4, a sticking layer, 5 and a stripping layer.
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. It will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted. The positional relationships depicted in the drawings are for illustrative purposes only and are not to be construed as limiting the present patent.
Example 1
As shown in figure 1, the absorbable and degradable dressing for inhibiting scars structurally comprises a silica gel layer 1, a first dressing layer 2, a second dressing layer 3, an adhesive layer 4 and a stripping layer 5; the first dressing layer 2 and the second dressing layer 3 are positioned on the same plane and uniformly cover the bottom of the silica gel layer 1. Wherein the first dressing layer 2 is absorbable hemostatic gauze; the second dressing layer 3 is composed of absorbable medical films with tissue induction function and different degradation time, a small amount of silver ions are uniformly loaded on the films, and the absorbable medical films are prepared from one or two of absorbable polyurethane, absorbable polyester, absorbable polyether, absorbable polyamino acid, absorbable carboxymethyl chitosan and absorbable hemostatic gauze; the adhesive layer 4 is a medical pressure-sensitive adhesive with low sensitization; the stripping layer 5 is a glassine silicone oil paper. In the above-described respective layer structures, the release layer 5 may completely cover the adhesive layer 4, the first dressing layer 2 and the second dressing layer 3.
