Description

TECHNICAL FIELD

[0001] The utility model relates to medical supplies technical field especially relates to a wound surface repair paste. BACKGROUND

[0002] The existing wound surface repair paste adopts the form of adhesive plaster, is adhered to the wound surface, but the replacement frequency of adhesive plaster is relatively higher, because the adhesive plaster often needs to be replaced because of the invalidation caused by bathing or daily activities, even if normal use, the use period of the drug effect is generally not more than 24 hours. But the wound cannot heal within 24 hours, at this time, when the adhesive tape of the adhesive plaster is torn, the wound is painful, and even the tearing of the adhesive tape can cause the risk of the wound to crack again, and the use experience is poor. SUMMARY

[0003] The utility model aims at providing a wound surface repair paste which is convenient to replace and reduces the impact on the wound.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a wound surface repair paste which comprises a fixing layer and a repair paste body.

[0005] The fixing layer is a flexible transparent PE layer in the form of a ring, and one side of the PE layer is coated with an adhesive.

[0006] The repair paste body is circular, the middle part of the repair paste body is a drug layer, the outermost circle of the repair paste body is a peeling edge, and the circle of the repair paste body close to the peeling edge is provided with an adhesive circle, and the ring diameter of the adhesive circle is matched with the ring diameter of the PE layer.

[0007] In this embodiment, the repair paste body comprises a breathable non-woven fabric as a bottom layer, the middle part of the bottom layer is a drug layer, and a liquid absorbing and water locking layer is further arranged between the drug layer and the bottom layer.

[0008] In this embodiment, the peeling edge is an edge of the bottom layer without adhesive.

[0009] In this embodiment, the thickness ratio of the fixing layer, the bottom layer and the drug layer is 1:1:2.

[0010] In this embodiment, a tearable release layer is covered on the adhesive surface of the fixing layer and the repair paste body.

[0011] Compared with the prior art, the wound surface repair paste of the utility model has the advantages that the fixing layer is adhered to the outer circle of the wound for a long time and does not need to be replaced. When the drug needs to be replaced, the repair paste body can be torn off, the adhesive layer of the repair paste body is adhered to the surface of the fixing layer, the relatively smooth PE layer on the surface of the fixing layer makes the tearing of the repair paste body more smooth, and the tearing of the repair paste body will not cause too much tearing of the skin, thereby avoiding the pain and the impact on the healing effect of the wound caused by frequent replacement of the drug. BRIEF DESCRIPTION OF DRAWINGS

[0012] Figure 1 An exploded view of the wound repair patch in the embodiments of the present application;

[0013] Figure 2 A surface view of the repair patch body in the embodiments of the present application. DETAILED DESCRIPTION

[0014] In order to make the purpose, technical scheme and advantages of the present application more clear, the technical scheme of the present application will be further described below.

[0015] As shown in Figure 1 and Figure 2 , the present application proposes a wound repair patch, which is composed of a fixing layer 1 and a repair patch body.

[0016] As shown in Figure 2 , the fixing layer 1 is a flexible transparent PE layer in the shape of a ring, one side of the PE layer is coated with an adhesive, the adhesive is medical glue, the flexible transparent PE layer in the shape of a ring is first adhered around the wound, and is adhered to the surface of the skin, the PE layer has a waterproof effect, and does not need to be removed during bathing, and can be used for a long time until the wound heals.

[0017] As shown in Figure 2 , the repair patch body is circular, breathable non-woven fabric is used as the bottom layer 2 to ensure the air permeability of the wound, the middle part of the bottom layer 2 is a drug layer 3, and a liquid absorption and water locking layer 6 is further arranged between the drug layer 3 and the bottom layer 2, the liquid absorption and water locking layer is a liquid absorption non-woven fabric, which is used to absorb exuded blood and other liquid tissues. A circle of adhesive is arranged at a position close to the outermost circle of the bottom layer 2, forming an adhesive ring 4, the adhesive ring 4 is matched with the ring diameter of the PE layer, and when the repair patch body needs to be adhered to the wound, the adhesive ring 4 is adhered to the surface of the PE layer. In order to facilitate the subsequent peeling and replacement of the repair patch body, no adhesive is arranged at the outermost circle of the repair patch body, forming a peeling edge 5, which is convenient for peeling. In order to further ensure that the drug layer 3 can be attached to the wound, the thickness ratio of the fixing layer 1: the bottom layer 2: the drug layer 3 is 1:1:2.

[0018] In this embodiment, when the medicament needs to be replaced, the repair patch body can be simply torn off, the adhesive layer of the repair patch body is adhered to the surface of the fixing layer 1, the surface of the fixing layer 1 is relatively smooth PE layer, the tearing of the repair patch body is smoother, and the skin is not torn too much, and the adhesive force between the two is smaller than the adhesive force between the fixing layer 1 and the skin, so that the fixing layer 1 is not torn off, and the pain caused by frequent replacement of the medicament and the effect of wound healing are effectively avoided.

[0019] In this embodiment, a tearable release layer is covered on the adhesive surfaces of the fixing layer 1 and the repair patch body for protection.

[0020] The above are only preferred embodiments of the present application, and do not have any limiting effect on the present application. Any person skilled in the art, without departing from the technical solution of the present application, makes any form of equivalent replacement or modification of the technical solution and technical content disclosed by the present application, and the change belongs to the content of the technical solution of the present application, and still belongs to the protection scope of the present application.
