Method for producing adsorption filtration mouth and nose cover

Abstract

The invention discloses a production method of an absorbing and filtering oral-nasal mask. The key points of the technical proposal lie in the production method of the absorbing and filtering oral-nasal mask. The production method is that: absorbent gauzes and sterilizing medical gauzes are respectively used at the left face and the right face of a natural mineral absorbing and filtering oral-nasal mask. The absorbing and filtering oral-nasal mask is made according to different shapes at the two faces of the natural mineral absorbing and filtering oral-nasal mask. The frontage of the absorbing and filtering oral-nasal mask is provided with four through holes and package is the finished product of the absorbing and filtering oral-nasal mask. The absorbing and filtering oral-nasal mask has good dustproof effect, which can absorb and filter respiratory dust and detrimental pathogenic bacteria of less than 5 microns, thus preventing dust and detrimental pathogenic bacteria from being directly sucked into pulmonary alveolus and guaranteeing body health of users. The invention is characterized by small breath resistance, light weight and being capable of absorbing peculiar smell and being reused for a plurality of times after sterilization and evaporation, which is applicable for producing three-dimensional absorbing and filtering oral-nasal masks with a shape like an arched plate.

Description

Technical field: [0001] The invention relates to a mouth and nose mask, in particular to a production method of an adsorption filter nose and mouth mask. Background technique: [0002] Working in an environment with dust or toxic gas for a long time, if you do not use a suitable protective mask, it will cause damage to the human respiratory system. The damage to lung organs and tissues is usually very serious and irreversible. The finer the dust, the easier it is to enter the end of the bronchi, and the greater the lethality. [0003] The dust blocking efficiency of the mask is based on its blocking efficiency for fine dust, especially for respirable dust below 5 microns, because dust of this particle size can be directly inhaled into the alveoli, which has the greatest impact on human health. The general gauze mask, its dust blocking principle is mechanical filtration, that is, when the dust hits the gauze, it passes through layers of barriers to block some large particles...
