Description

Novel transparent wound subsides

Technical Field

The utility model relates to the field of medical dressing, in particular to a novel transparent wound patch.

Background

The medical dressings are various, and the earliest medical dressings have specific shapes such as rubberized fabric, sterilized gauze, sterilized medicine soaked gauze, sterilized non-woven fabric with tiny pores and the like, and can be used as required, but the medical dressings have the defects of troublesome use and inconvenient operation. In order to overcome the drawbacks of the above surgical medical dressings, wound patches, transparent dressings, and the like have been invented in recent years.

The wound plaster mainly comprises a flat cloth adhesive tape and a medicated water absorbing pad, and has hemostatic and wound protecting effects. However, the prior adhesive plaster for wound plaster has poor air permeability and water permeability, and the water vapor and sweat normally secreted by the local part of the human body can not penetrate through the adhesive plaster, so that the adhesive plaster can soak the local skin, and bacteria can be easily caused to grow for a long time, thus the wound is worsened. The transparent dressing has the advantages of strong skin affinity, high bonding fastness, good waterproof function and the like, is deeply favored by vast medical staff, but the whole surface of the transparent dressing fixing bonding layer of the extremely thin and soft transparent bionic film is covered with a layer of adhesive coating layer, and the adhesive coating layer is firmly bonded and is not easy to peel off due to the airtight effect of the adhesive coating layer, so when the transparent dressing is required to be peeled off after being used, the skin is often damaged due to peeling off of the transparent dressing, and in addition, the air permeability of the transparent dressing is very poor due to the airtight effect of the adhesive coating layer.

Disclosure of Invention

The utility model aims to overcome the defects existing in the prior art and provides a novel transparent wound patch.

The technical scheme for achieving the purpose of the utility model provides a novel transparent wound patch, which comprises a wound patch, wherein the wound patch comprises an absorption layer, a transparent waterproof outer film and a medicine applying layer, the absorption layer is arranged in a groove above the transparent waterproof outer film, the medicine applying layer is arranged in the center of the absorption layer, a flow guide layer is arranged above the medicine applying layer, a glue coating layer is arranged at the edge above the absorption layer, and a wound patch adhesive film is adhered and covered on the wound patch.

Further, a diversion trench is arranged on the diversion layer.

Further, the absorbing layer is made of sponge materials.

Furthermore, the transparent waterproof outer film is an ultrathin soft transparent bionic film made of PU polyurethane materials.

Further, the glue coating layer is distributed by adopting a glue coating area and a non-glue coating area.

Further, the gluing areas and the non-gluing areas are arranged in a point-block-shaped interval distribution.

Further, the groove above the transparent outer film is of a square structure.

Further, the four corners of the transparent outer film are all set to be arc corners.

After the technical scheme is adopted, the utility model has the following positive effects:

(1) The adhesive layer is distributed at intervals between the adhesive area and the non-adhesive area, and when the transparent wound patch is required to be peeled after being used, the damage to the skin caused by peeling the wound patch is avoided, and the peeling is convenient.

(2) The transparent waterproof outer film is an ultrathin soft transparent bionic film made of PU polyurethane materials, and the part of the adhesive coating layer without adhesive coating can be ventilated through the original ventilation holes of the ultrathin soft transparent bionic film with high moisture permeability, so that the ventilation property of the transparent wound plaster is greatly improved.

(3) The utility model is provided with the diversion layer, the diversion layer diverts the seepage on the wound surface into the absorption layer, and the absorption layer adopts sponge materials, so that the absorption layer has strong absorption capacity, high absorption multiplying power and wider adaptability.

(4) The utility model has simple and reasonable structure, comfortable and convenient use, good liquid absorption performance, extremely thin and soft transparent bionic film with high moisture permeability, improves the air permeability of the transparent wound plaster, reduces the adhesion between the wound plaster and the skin by the adhesive coating areas distributed at intervals, is convenient for the wound plaster to be torn off from the affected part, and ensures that the wound plaster is more convenient and practical to use.

Detailed Description

Example 1

As shown in fig. 1 to 4, the utility model is a novel transparent wound patch, wherein the wound patch 2 comprises an absorption layer 21, a transparent waterproof outer film 22 and a medicine applying layer 23, the absorption layer 21 is arranged in a groove above the transparent waterproof outer film 22, the absorption layer 21 is made of sponge materials, and the groove is of a square structure. The central point of the absorption layer 21 is provided with an application medicine layer 23, a diversion layer 25 is arranged above the application medicine layer 23, and a diversion trench is arranged on the diversion layer 25. The upper edge of the absorption layer 21 is provided with a rubberized layer 24, and the rubberized layer 24 is formed by arranging rubberized areas 3 and non-rubberized areas 4 in a point-block-shaped interval distribution. The wound plaster 2 is covered with a wound plaster adhesive film 1. The transparent waterproof outer film 22 is an extremely thin and soft transparent bionic film made of PU polyurethane material, and four corners are all arc corners.

The working principle of the utility model is as follows: when the novel transparent wound plaster is used, a patient tears off the wound plaster adhesive film 1 by hands, the plaster layer 23 on the absorption layer 21 is aligned with the wound surface and is pasted on the affected part, the gluing area 3 of the gluing layer 24 at the peripheral edge of the absorption layer 21 is tightly pasted on the body, and the middle part of the absorption layer 21 is not sticky with the non-gluing area 4. After the coating is completed, the seepage at the wound firstly enters the absorption layer 21 through the diversion trench of the diversion layer 25, and the absorption layer 21 is made of sponge material, so that the absorption layer 21 has strong absorption capacity and high absorption multiplying power. The transparent waterproof outer film 22 of the wound plaster 2 is an extremely thin and soft transparent bionic film with high moisture permeability made of PU polyurethane material, has waterproof and air permeability, can allow oxygen and water vapor to exchange, is antibacterial, and effectively blocks external pollution. The adhesive coating layer 24 is distributed at intervals between the adhesive coating area 3 and the non-adhesive coating area 4, so that the adhesion between the wound plaster and the skin is reduced while the normal use of the wound plaster is ensured, and when the transparent wound plaster is required to be peeled after the use, the damage to the skin caused by peeling the wound plaster is avoided, and the peeling is convenient.

While the foregoing is directed to embodiments of the present utility model, other and further details of the utility model may be had by the present utility model, it should be understood that the foregoing description is merely illustrative of the present utility model and that no limitations are intended to the scope of the utility model, except insofar as modifications, equivalents, improvements or modifications are within the spirit and principles of the utility model.
