Description

Antifogging device with nose support

Technical Field

The utility model belongs to the technical field of medical instruments, and particularly relates to an anti-fog device with a nose support.

Background

Along with the enhancement of modern people to public health protection consciousness, wearing gauze mask is more and more popular going out, especially in this year's anti novel coronavirus infection pneumonia period, traditional gauze mask adopts the non-woven fabrics to make usually, and the user covers the oronasal part through the gauze mask after wearing the gauze mask to filter the air through the non-woven fabrics. The common mask has two disadvantages. Firstly, the non-woven fabric and the external contour of the mouth and nose part of a human body with a complex shape cannot be tightly attached, so that the air tightness is poor, and part of exhaled or inhaled air flow is easy to leak from the gap between the mask and the nose wing, so that the filtering effect of the mask is greatly reduced, and even some risks can be brought to users in some industries, for example, medical staff must wear the mask at any time during work, but the air flow at the gap between the mask and the nose wing can bring bacteria and virus carriers from the external environment, so that the risk of infection and disease is brought. Patients with infectious diseases can also exhale the virus carrier when wearing the mask, and other people are harmed. Secondly, a large amount of water mist exhaled by a person wearing the glasses in winter leaks upwards along the gap between the mask and the nose wing and is condensed on the lenses, so that the sight is seriously obstructed, and great inconvenience and potential safety hazards are brought to the person wearing the glasses; simultaneously because the top edge of gauze mask can lead to certain interference to the nose of glasses holds in the palm to if the user who leads to wearing the gauze mask after wearing the glasses again, take place the problem that the glasses slided very easily, often need manual rightting, it is very inconvenient.

Many other devices for preventing the generation of fog on eyeglasses while wearing oronasal protective devices have appeared in the prior art. For example, chinese patent with patent number CN111567929A discloses an anti-fogging mask, relates to the field of sanitary products, aims at solving the problem that glasses fog easily when wearing the mask, and the technical scheme main points are: the utility model provides an anti-fogging mask, includes the gauze mask main part, sets up a pair of hangers portion in gauze mask main part both sides, sets up the bridge of the nose strip that corresponds human bridge of the nose position in the gauze mask main part, the gauze mask main part has the multilayer structure of outmost, intermediate level and inlayer at least, be provided with the locating hole between outmost and the intermediate level, the locating hole runs through outmost being used for supplying the nose to hold in the palm to stretch into and block. The anti-fogging mask disclosed by the utility model can be matched with glasses when being worn, on one hand, the mask can be compressed to avoid gas overflow, and in addition, the positions of the glasses can be adjusted after the mask is worn, so that water vapor is prevented from being generated on the lenses, and the anti-fogging function can be effectively realized. However, the device realizes the compressing effect of the nose bridge strip through the pulling force effect of the ear hanging part, and the nose bridge is irregular in shape, so that the better compressing effect can not be realized only by the pulling force of the two sides of the ear, and a hole is formed between the nose bridge and the mask, and the better anti-fog effect can not be realized. Therefore, there is a need for improvement in the art to obtain an anti-fogging device with a nose pad that provides a better anti-fogging effect.
