Abstract

The utility model discloses a ventilative dressing of wound isolated form, the ventilative dressing body that has the pressure-sensitive adhesive including the lower surface, the lower surface middle part at ventilative dressing body has set firmly cotton imbibition pad, paste the antiseized layer that the cotton imbibition pad was inherently covered at the pressure-sensitive adhesive of ventilative dressing body lower surface, the installation cavity has been seted up in the center department of cotton imbibition pad, the wound shield who encloses by stereoplasm roof and stereoplasm side wall has set firmly in the installation cavity, the height of wound shield is unanimous with the thickness that cotton imbibition pad, the equipartition has a plurality of bleeder vents on the roof of wound shield. The utility model has the advantages of simple structure and convenient use. The wound is separated by the wound isolation cover, so that a cavity is formed on the surface of the wound and is not directly contacted with the cotton liquid absorption pad, the air permeability of the wound is increased through the air holes formed in the top wall of the wound isolation cover, the scabbing and healing of the wound are accelerated, and the wound isolation cover is particularly suitable for the wound with less blood seepage amount or the later-stage blood seepage amount of the wound.

Description

Wound isolated breathable dressing

Technical Field

The utility model relates to a medical treatment consumptive material especially relates to a ventilative dressing of wound isolated form.

Background

The medical dressing mainly comprises two types of breathable dressings and transparent dressings. The breathable dressing is similar to a wound plaster, and structurally comprises a breathable outer layer (dressing body) with a pressure-sensitive adhesive on the lower surface, a cotton liquid absorption pad is fixedly arranged in the middle of the lower surface of the breathable outer layer, an anti-sticking layer for covering the cotton liquid absorption pad is stuck on the pressure-sensitive adhesive on the lower surface of the breathable outer layer, and the cotton liquid absorption pad is directly stuck to a wound when in use; because the thicker cotton absorbent pad needs to be directly pressed and fixed on the wound, the air permeability is relatively poor, and the wound is not favorable for scabbing and healing of the wound, especially for the wound with less amount of blood seepage or for the wound with less amount of blood seepage at the later stage.

Disclosure of Invention

The utility model aims to provide a wound isolated form breathable dressing which is simple in structure and convenient to use.

In order to achieve the above purpose, the utility model can adopt the following technical proposal:

wound isolated form dressing that breathes freely, have the ventilative dressing body of pressure sensitive adhesive including the lower surface middle part of ventilative dressing body has set firmly cotton and has inhaled the liquid pad, pastes inherent cover on the pressure sensitive adhesive of ventilative dressing body lower surface the antiseized layer of cotton imbibition pad the installation cavity has been seted up to the center department that cotton imbibition pad was inhaled, the installation cavity has set firmly the wound cage of enclosing by stereoplasm roof and stereoplasm side wall, the height of wound cage with the thickness that cotton imbibition pad is unanimous, and the equipartition has a plurality of bleeder vents on the roof of wound cage.

And a cotton liquid absorption film is adhered to the inner wall of the wound isolation cover, and communication holes which correspond to the air holes one by one are formed in the cotton liquid absorption film.

The lower surface of the cotton liquid absorption pad and the lower edge of the side wall of the wound isolation cover are coated with hydrogel thin layers.

The utility model has the advantages of simple structure and convenient use. The wound is separated by the wound isolation cover, so that a cavity is formed on the surface of the wound and is not directly contacted with the cotton liquid absorption pad, the air permeability of the wound is increased through the air holes formed in the top wall of the wound isolation cover, the scabbing and healing of the wound are accelerated, and the wound isolation cover is particularly suitable for the wound with less blood seepage amount or the later-stage blood seepage amount of the wound is reduced; the wound nursing at the easily worn parts such as joints is convenient, the unnecessary wear of the wound is reduced, and the wound healing is promoted.

Detailed Description

As shown in fig. 1 and 2, the wound isolated type air-permeable dressing of the present invention comprises an air-permeable dressing body 1 with a pressure-sensitive adhesive on the lower surface, a cotton liquid-absorbing pad 2 is fixedly arranged in the middle of the lower surface of the air-permeable dressing body 1, an anti-sticking layer 3 which is inherently covered on the cotton liquid-absorbing pad 2 is stuck on the pressure-sensitive adhesive on the lower surface of the air-permeable dressing body 1, an installation cavity is arranged at the center of the cotton liquid-absorbing pad 2, a wound isolating cover 4 enclosed by a hard top wall and a hard side wall is fixedly arranged in the installation cavity, the wound isolating cover 4 can be generally made of plastic, and can be set with specific sizes according to the size of a long wound; the height of the wound isolation cover 4 is consistent with the thickness of the cotton liquid absorption pad 2, and the lower edge of the wound isolation cover 4 is flush with the lower surface of the cotton liquid absorption pad 2, so that the wound isolation cover is convenient to adhere; a plurality of air holes 5 are uniformly distributed on the top wall of the wound isolation cover 4, the air holes 5 can increase the air permeability of the wound, and meanwhile, the air permeable dressing body 1 on the outer side of the air holes 5 can effectively prevent dust and bacteria from entering the wound.

In general, blood or effusion exuded from the wound can flow from the edge of the wound isolation cover 4 to the cotton absorbent pad 2 and be absorbed by the cotton absorbent pad; in order to enhance the liquid absorption capacity, a cotton liquid absorption film 6 can be adhered and fixed on the inner wall of the wound isolation cover 4, and the liquid absorption capacity of the dressing is improved to a certain extent through the cotton liquid absorption film 6; and in order to prevent the cotton liquid-absorbing film 6 from obstructing the air holes 5, the cotton liquid-absorbing film 6 is provided with communicating holes 7 which are in one-to-one correspondence with the air holes 5. In addition, in order to avoid discomfort to the skin around the wound, the lower surface of the cotton pad 2 and the lower edge of the side wall of the wound shield 4 are coated with a thin layer 8 of hydrogel.

Directly tear antiseized layer 3 down during the use, aim at wound cage 4 the wound and paste admittedly can, wound isolated form ventilative dressing be applicable to more when oozing less wound of blood volume or wound later stage oozing blood volume and reduce, make things convenient for easy wearing and tearing position department wound nursing such as joint, reduce the unnecessary wearing and tearing of wound, promote wound healing.
