Medical protective mask based on nanometer photodynamic effect

Abstract

The invention provides a medical protective mask based on a nanometer photodynamic effect. The mask comprises an outer layer, an inner layer and a middle layer arranged between the outer layer and theinner layer, symmetrical tensioning belts are arranged on the front side and the rear side of the side wall of the right side of the inner layer, and the medical protective mask is characterized in that the middle layer comprises a left filter layer attached to the side wall of the right side of the outer layer and a right filter layer attached to the side wall of the inner layer; a nanometer material photosensitizer layer is arranged between the left filtering layer and the right filtering layer; the material of the nanometer material photosensitizer layer is Cu-Cy; and a silver nanoparticlelayer is arranged between the left filter layer and the nano material photosensitizer layer. According to the medical protective mask based on the nanometer photodynamic effect, the structure and performance of the medical protective mask are not damaged while disinfection and sterilization can be achieved through the photodynamic effect, the recyclable effect is achieved, and the situation thatthe medical protective mask is insufficient is avoided.

Description

technical field [0001] The invention relates to a medical protective mask, in particular to a medical protective mask based on nano photodynamic effect. Background technique [0002] The medical protective mask is composed of a mask body and a tension belt. The mask body is divided into three layers: inner, middle and outer. The outer layer is non-woven fabric, which plays a water-repellent effect. The inner layer is made of non-woven fabric, which has moisture absorption and skin-friendly effects. Most of the epidemics are transmitted by respiratory droplets and close contact. The possibility of aerosol transmission, and the crowd is generally susceptible, so when an epidemic occurs, medical protective masks can effectively cut off the transmission route and control the epidemic, while traditional medical protective masks must be replaced within 4 hours in a highly polluted environment However, due to the sudden outbreak, long duration and wide coverage of the epidemic, th...
