Non-oleaginous non-sticky antimicrobial dressing

Abstract

The invention discloses a non-oleaginous non-sticky antimicrobial dressing which is formed by sewing multiple functional structure layers from inside to outside. The functional structure layers comprise an antimicrobial non-sticky layer which is composed of an upper covering layer, a lower covering layer and a sustained release layer, an active biological antimicrobial preparation with positive charges is adsorbed in gaps among molecules of the upper covering layer and the lower covering layer, the sustained released layer is arranged between the upper covering layer and the lower covering layer, the sustained covering layer is composed of a sustained-release diaphragm containing the antimicrobial preparation, a discoloring layer is laminated on the outer surface of the antimicrobial non-sticky layer, the color of the discoloring layer changes from red to purple along with reducing of the antimicrobial preparation in the antimicrobial non-sticky layer structure, a polymer absorption layer is laminated on the outer surface of the discoloring layer, an auxiliary layer is laminated on the outer surface of the polymer absorption layer, a waterproof layer is laminated on the outer surface of the auxiliary layer, and sticky tape is arranged on the surface of the waterproof layer. According to the non-oleaginous non-sticky antimicrobial dressing, stronger antimicrobial and non-sticky effects are achieved, physical bacteriostasis is adopted simultaneously, toxic and side effects do not exist, the replacement period of the dressing can be marked clearly, the adhesion function is achieved, and use is convenient and fast.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a non-oily, non-adhesive and antibacterial dressing. Background technique [0002] Gauze is a kind of cotton fabric with sparse warp and weft, and its surface has obvious grids. According to its use, it can be divided into civil gauze, industrial gauze and medical gauze. Medical absorbent gauze and absorbent cotton are used in the medical industry for wound dressing, protection, cleaning, etc. The main hygienic material used is a natural care material that can be used safely. It is indispensable in medical institutions, but there are currently the following problems: First, the covering surface of the gauze is applied to the wound of the patient, and it is easy to adhere to the wound of the patient. , causing secondary damage to the wound; second, the gauze covers the wound of the patient, and the healing of the wound varies, so the replacement cycle of the gauze depends...

AI Technical Summary

Problems solved by technology

[0003] The invention discloses a non-oily non-adhesive antibacterial dressing, which is used to solve the problems in the traditional technology that the antibacterial time of the dressing is short, the wound surface is adhered, the replacement period cannot be accurately judged, and the dressing is easy to fall
