Functional dressing (film)

Abstract

A functional dressing (film) comprises an edge remaining film 1 and a fixed pasting film 2 which are convenient to separate from each other, wherein a functional pad 3 is arranged between the edge remaining film 1 and the fixed pasting film 2, a protective film 4 is arranged on the face, with the back towards the functional pad, of the fixed pasting film, and a plurality of layers of annular adhesive tape or adhesive tape shaped like a Chinese character 'hui' is arranged on the fixed pasting film. Thus, on the one hand, the binding area of the fixed pasting film and the skin is reduced, and on the other hand, sweat can volatilize through reserved gap; due to the fact that a functional layer and a moisture-preserving layer are arranged in the functional pad, medicine ingredients in the functional layer and the moisture-preserving layer act on wounds and peripheral tissue, and the functional dressing (film) has the functions of stopping bleeding, resisting and preventing bacteria, diminishing inflammation, easing pain, promoting healing, reducing scar formation and accelerating local blood circulation.

Description

technical field [0001] The invention belongs to the technical field of medical supplies, and in particular relates to a functional dressing (membrane) for body surface tissue wounds, ulcer wounds and repair wounds. Background technique [0002] Most of the current wound dressings have the function of anti-inflammation, but generally do not have the function of analgesia, and do not have the function of using far infrared rays to radiate the body tissues around the wound to improve blood circulation and relieve pain. [0003] Because the application will be polluted by wound overflow fluid and the efficacy of the medicine will be reduced after long-term use, it needs to be replaced in time. However, in the use of the current applicator, it is often found that the wound has been infected and inflamed when the applicator is torn off. At this time, the wound is treated again, and the healing time becomes longer accordingly, and the scar left after the wound is healed is more obv...

Problems solved by technology

[0003] Because the application will be polluted by wound overflow fluid and the efficacy of the medicine will be reduced after long-term use, it needs to be replaced in time

However, in the current application, it is often found that the wound has been infected and inflamed when the application is torn off. At this time, the wound is treated again, and the healing time is correspondingly longer, and the scar left after the wound is healed is more obvious

[0004] In addition, most of the existing applicators are fixed on the skin by coating medical glue on the fixed film, and the medical glue on the fixed film is usually applied in a full-width way, which has the advantage of being able to effectively fix The disadvantage is that when the fixed film is torn off from the skin, it is easy to pull the skin and cause pain at the wound site, and the application sticks to the skin for a long time, the fluid cannot be discharged, and it is easy to cause skin allergies

[0005] In the patent application number 200410025842.9, a design method for postoperative incision application is disclosed. A permanent magnetic sheet is fixed on the application to generate a magnetic field to promote wound healing. A spunlace cloth is connected to the middle of the self-adhesive base layer. The water-absorbent cotton core is wrapped in the spunlace cloth, and the permanent magnet sheet is pasted on the absorbent cotton core, which has good moisture retention and a certain pain-relieving effect. Because the permanent magnet sheet has strong hardness and a certain thickness, it is incompatible with the When replacing, the permanent magnet sheet is likely to cause a certain pressure on the wound and cause pain; the iron content is high, the wound will overflow, and it is easy to rust and cause secondary pollution to the wound
