Description
Technical Field
The invention belongs to the technical field of medical protection, and particularly relates to an anti-fog goggles with a face screen.
Background
When operations such as collecting throat swabs, sucking phlegm, trachea intubation and puncturing are carried out, infected patients have risks of spit or liquid splashing to a mask or goggles and the like, potential infection risks are caused to medical staff, a face screen is added in front of the goggles in the conventional popular method, so that long-time wearing discomfort can be caused, infection risks of the face screen and the goggles are increased, and visual fields or deviation can be influenced due to the fact that light is refracted through three layers of objects (light-face screen-air-goggles).
The medical goggles can form a closed space with the face and eyes of a user, and aerosol, liquid splashing and the like can be avoided. But because the medical protective mask is tightly pressed below the medical goggles, the nose exhales gas to enter the goggles, the moisture and heat trapped in the goggles are increased, meanwhile, the temperature difference is generated between the nose exhales gas and the goggles, dew condensation similar to fog is formed on the inner surface of the goggles, finally, aerial fog is formed, the visual field of medical staff is influenced, and certain inconvenience can be caused to diagnosis and treatment activities.
The present invention focuses on sports and industrial protection, and the main measures include passive increase of gas flow (goggle air inlet), active increase of gas flow (blowing external gas into enclosed space) and electric heating device. Because the medical goggles are special, need to be closed, cannot exchange gas with the outside, and can avoid blowing outside aerosol into eyes and other areas, the measures of passively and actively increasing gas flow cannot be adopted at present. The goggles are mostly disposable simultaneously, even the goggles will be soaked in the disinfection liquid and soak when the material lacks, so there is the risk of short circuit to present electrical heating's electronic component.
