AI Technical Summary

Problems solved by technology

The particle filtration efficiency of medical surgical masks is only 30%. The bridge of the nose is thin and soft, and the fit and airtightness are poor. It is easy to cause air leakage on both sides of the bridge of the nose and reduce the protective effect.
The particle filtration efficiency of the N95 mask has reached 95%, and the protective effect is good. However, due to the strong airtightness of the filter material and poor air permeability, wearing it for a long time will cause hypoxia, dizziness, suffocation and other discomfort.
In addition, the hardness of the sealing aluminum strip on the bridge of the nose is too high, long-term use will cause skin damage, and the exposure of the wound also increases the possibility of infection

Embodiment

[0052] The cover fabric of the mask body 110 is a melt-blown non-woven layer, an electretized electrostatic layer, and a negative oxygen ion layer from the inside to the outside;

[0053] Melt-blown non-woven fabrics are suitable for air filtration. The air filter series is composed of PP / PET two-component composite materials with a three-dimensional network structure. PET materials play a role in supporting the skeleton and provide the stiffness of the filter layer. Make the material have lower resistance while ensuring efficiency;

[0054] The electret electrostatic layer uses static electricity to adsorb small particles in the air, which has the advantages of higher filtration efficiency, higher filtration precision, smaller resistance, larger dust holding capacity, and longer life. It can effectively filter particles with a pollen particle size of one percent , can capture particles equivalent to one fortieth of the diameter of a hair.

[0055] The electret electrostatic ...

Abstract

The invention discloses a novel hydrogel electrostatic electret polarization protective mask. The mask comprises: a mask body; a flexible framework supporting part arranged along the inner side of themask body, wherein the shape of the framework supporting part is matched with the shape of the face of a user; a flexible sealing strip arranged along the inner side of the edge of the mask body andused for enabling the mask body to be tightly attached to the face of a user; and two hanging lugs symmetrically arranged on the outer sides of the left side and the right side of the mask body.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a novel hydrogel electrostatic electretization protective mask. Background technique [0002] As a kind of protective equipment, masks can filter the air entering the respiratory tract. According to different filter materials, different types of masks can filter dust, pollen, smog, bacteria, virus droplets and other particles to varying degrees. Masks can not only be used for the basic protection needs of daily life, but also play a very important role in the protection of various respiratory infectious diseases. During the epidemic prevention process of the SARS outbreak in 2003, the bird flu outbreak in 2004 and 2009, and the new crown pneumonia epidemic in 2020, wearing a mask has become the simplest and most effective way to effectively block the spread of the virus and protect people's lives. Protective measures. [0003] The study found that in the 2020 new crown ...
