Abstract

The utility model relates to a windowing woundplast which is characterized in that the woundplast comprises a sticking layer which has stickness on the lower surface, and an upper sticking layer which can be stuck on the upper surface of the lower sticking layer; the middle of the lower sticking layer is provided with a window which is through up and down; and the middle of the lower surface of the upper sticking layer is provided with a drug layer which can downwards extend into the window. The utility model not only can avoid damaging the wound during dressing changing and wound observation, but also can reduce the use cost.

Description

The window type adhesive bandage

Technical field

This utility model relates to adhesive bandage, particularly a kind of window type adhesive bandage.

Background technology

Present adhesive bandage all is made up of monolayer adhered layer and the medicine layer of being located at adhered layer lower surface middle part; after this adhesive bandage is bonded at the wound; if wound is changed dressings or will observe the situation of wound the time; whole layer adhered layer must be torn together with medicine layer; because adhered layer all is adjacent wound location basically; make the skin of wound circumference be subjected to tractive and injure wound when therefore tearing easily, bring very big inconvenience for like this user that need often change dressings or observe wound.In addition,, be difficult to reuse again, therefore often change dressings or observe the user of wound, also cause waste to a certain degree for needs because the common viscosity of adhered layer after tearing reduces.

The utility model content

The purpose of this utility model is to provide a kind of window type adhesive bandage, and it not only can be avoided changing dressings or injure wound when observing wound, and can reduce use cost.

Technical solutions of the utility model are to constitute like this, and a kind of window type adhesive bandage is characterized in that: it comprises that lower surface has the last adhered layer on the upper surface of the following adhered layer of viscosity and Pasting infra adhered layer; The middle part of following adhered layer offers penetrating window up and down; The lower surface middle part of last adhered layer is provided with the medicine layer that can stretch in the window downwards.

This utility model window type adhesive bandage will descend adhered layer to stick on the skin earlier in use, make wound be positioned at window area during stickup; To go up again on the upper surface that adhered layer sticks at down adhered layer, and make during stickup under the medicine course and stretch in the window, and wound be covered (perhaps will go up adhered layer and following adhered layer earlier and be pasted together, and make during stickup under the medicine course and stretch in the window; To descend adhered layer to stick on the skin again, and make medicine layer cover wound during stickup).When user need be changed dressings or be observed wound, only need to go up adhered layer and tear up, can raise medicine layer, medicine layer is changed or wound is observed.Because last adhered layer just sticks on down on the adhered layer, less than with the contact skin of wound circumference, therefore, on tearing during adhered layer, skin that can the tractive wound circumference and influence the healing of wound.In addition, often change dressings at short notice or observe the user of wound for needs, owing to change dressings or when observing wound, only need tear adhered layer, following adhered layer can be stayed and use on the skin long period, so helps reducing use cost.

Than prior art, the utlity model has following advantage: (1) is changed dressings or is observed wound and can avoid injuring wound constantly, is particularly useful for suppurative wound and other wound that need often change dressings or observe.(2) help reducing use cost.

The specific embodiment

Below in conjunction with specification drawings and specific embodiments this utility model content is elaborated:

As Fig. 1-Figure 4 shows that a kind of embodiment organigram of the window type adhesive bandage that this utility model provides, it comprises that lower surface has the last adhered layer 2 on the upper surface of the following adhered layer 1 of viscosity and Pasting infra adhered layer 1; The middle part of following adhered layer 1 offers penetrating window 3 up and down; The lower surface middle part of last adhered layer 2 is provided with the medicine layer 4 that can stretch in the window 3 downwards.During making, described medicine layer 4 can be the lower surface that directly is fixed on adhered layer 2; Described medicine layer 4 also can be independently, in taping process, by last adhered layer 2 medicine layer 4 is fixed in the window 3.

The shape and size of described medicine layer 4 can adapt respectively with the shape and size of window 3.The zone that medicine layer 4 is covered can be suitably more than or equal to or be slightly less than 3 area surrounded of window, when as long as infra adhered layer 1 and last adhered layer 2 are pasted, can guarantee that medicine layer 4 stretches in window 3 districts contacts with wound, and the following adhesive surface of last adhered layer 2 can not adhere to skin (in the time of can guaranteeing on tearing adhered layer like this, can not cause tractive to the skin of wound circumference) and go up and get final product.

When changing medicine layer again, can guarantee to go up adhered layer 2 and form viscosity preferably with following adhered layer 1, described adhered layer 2 lower surfaces of going up have viscosity, last adhered layer 2 is pasted on down on the upper surface of adhered layer 1 by its viscosity lower surface, like this when changing dressings, the available new last adhered layer 2 that has the medicine layer after the replacing sticks on down on the adhered layer 1.Certainly, the window peripheral region that descends adhered layer 1 upper surface can be made yet and to have viscosity, the lower surface of adhered layer 2 cannot not make stickingly and go up, and both are connected, but when changing dressings, be unfavorable for like this repeating pasting new on adhered layer 2.

Be not pulled to skin for the ease of tearing adhered layer 2, the described best zone that outward flange covered, the zone that outward flange covered of going up adhered layer 2 less than following adhered layer 1.As shown in FIG., described adhered layer 1 down and last adhered layer 2 are the strip shape, and the part that last adhered layer 2 exceeds medicine layer length direction both sides is shorter than down the part that adhered layer 1 exceeds length of window direction both sides respectively, and the part that last adhered layer 2 exceeds medicine layer width both sides equals respectively or is shorter than down the part that adhered layer 1 exceeds window width direction both sides.Certainly, described down adhered layer 1 and last adhered layer 2 are not limited to illustrated strip shape, also can be Else Rule or irregular different shapes such as square circular or oval or blade shaped.The zone that outward flange covered that the described zone that outward flange covered of going up adhered layer 2 is equal to or greater than down adhered layer 1 also is fine.
