Goggles for preventing 2019-nCoV

Abstract

The invention belongs to the technical field of virus protection, and in particular relates to goggles for preventing 2019-nCoV. The goggles of the invention include a goggles frame, resin lenses, a rubber ring, a protective cloth and an elastic band; two resin lenses are embedded in the goggles frame through goggles frame clamping grooves; the inner side of the rubber ring can be closely attachedto eyes of a human face, the protective cloth is located between the rubber ring and the goggles frame, and the rubber ring and the goggles frame are connected, supported, and fixed by a plurality ofsupporting strips; the elastic band is tied to two sides of the rubber ring for wearing the goggles on a head; and the protective cloth uses a composite high-efficiency material for preventing the 2019-nCoV, and is composed of three layers of materials, the inner and outer layers are prepared from polypropylene fiber spunbond nonwoven fabrics, and the middle layer is prepared from an ultrafine denier electret melt-blown fiber nonwoven fabric. The surface of the nonwoven fabric has a resident electrostatic field, the 2019-nCoV can be captured by the electrostatic field and a weak current generated by the microfiltration filter material when passing through gaps of the microfiltration filter material, and the goggles have good air permeability, and meet the N99 standard of the National Institute of Occupational Safety and Health (NIOSH).

Description

technical field [0001] The invention belongs to the technical field of virus protection, and in particular relates to goggles for highly effective protection against the novel coronavirus. Background technique [0002] Coronaviruses are a large class of viruses that widely exist in nature. The diameter of their virus particles is 60-120nm, with an average diameter of 100nm, and they are spherical or ellipsoidal. The 2019 novel coronavirus (2019-nCoV, causing COVID-19) is the seventh known coronavirus that can infect humans. Common signs of patients infected with coronavirus include respiratory symptoms, fever, cough, shortness of breath and dyspnea. In more severe cases, infection can lead to pneumonia, severe acute respiratory syndrome, multi-organ failure, and even death. In view of the strong infectivity of the new coronavirus, health and epidemic prevention experts emphasize that the transmission routes of new coronary pneumonia that can be determined at present are ma...

Problems solved by technology

[0003] However, there is currently a lack of goggles on the market that specifically protect against the new coronavirus

Most of the existing goggles on the market are made of plastic, plexiglass, etc., and the quality varies. After wearing for a long time, a large amount of fog will accumulate on the lens and even condense into water droplets, which seriously affects the normal work of medical staff.

For this reason, in recent years, manufacturers of medical goggles have continuously studied various anti-fog agents to improve the anti-fog ability of the lens, but the effect is not ideal. Potential Risk of Skin Sensitization
