Description

Medical personnel use high-efficient safe anti-virus gauze mask

Technical Field

The invention belongs to the technical field of medical supplies, and particularly relates to a high-efficiency safe anti-virus mask for medical staff.

Background

At present, pathogenic microorganisms such as bacteria and viruses seriously threaten the health of people. From the outbreak of SARS virus epidemic in 2003 in china to the major outbreak of ebola virus in 2014 to the major outbreak of the novel coronavirus in 2020 in west africa worldwide, the viral disease seriously threatens human life health. During virus outbreaks, a large number of virus carriers are sent to hospitals for treatment, so that medical workers are the most frequently and most frequently exposed to viruses, and the physical conditions of the medical workers are important concerns.

The edge of the upper part of the existing medical anti-virus mask is provided with a metal shaping strip more, the metal shaping strip is pressed, the shape of the mask is consistent with the human body face line, the mask is in contact with the human body skin, the tightness in the mask is improved, the air is prevented from flowing into the mask from the gap between the mask and the skin, the anti-virus effect is improved, although the existing medical mask is provided with the shaping strip, after the mask is worn, a small gap can exist between the mask and the skin, because medical staff contacts a large amount of viruses every day, in order to make protective measures, the medical staff must make the mask tighter, the mask can be in close contact with the skin, the time is long, under the extrusion effect of the shaping strip, the skin at the nose bridge of the medical staff is worn more or less, and the comfort degree of wearing the mask is seriously affected.

Moreover, most of the existing medical masks are fixed by sleeving the elastic bands behind the ears or on the heads, and when the elastic bands are sleeved behind the ears for a long time to fix the masks, the blood circulation of the ears is poor, and the ears are painful, and the masks are sleeved on the ears for a long time, so that the problem of insecure fixation of the masks is also caused; when fixing the gauze mask with the elastic band cover at user's head, because the elastic band is more thin, the long-time cover goes out the condition of slippage or displacement easily after overhead, and then leads to the gauze mask position to change, the problem of sealed effect variation, moreover, because everyone's head is not of uniform size, during the use, just can be fit for with user's head size after having knotted the processing to the elastic band, lead to wearing the slow problem of speed.
