Ultraviolet disinfecting and killing mask
Technical Field
The invention relates to the technical field of precision medical equipment, in particular to an ultraviolet sterilizing mask.
Background
The mask is the most common sanitary article around our body, and the mask is worn at the mouth and nose part and used for filtering air entering the mouth and nose so as to achieve the effect of blocking substances such as spray, viruses and the like. At present, the mask on the market uses cotton cloth, gauze or paper as main materials, and because the mask has certain barrier effect on breathing, the situation of chest distress and dyspnea may occur after the mask is worn for a long time. In order to let breathe unobstructed, improve the comfort level, some gauze masks have the breather valve, but this kind of gauze mask with breather valve has some shortcomings, and the valve probably is impaired on the one hand, causes gas leakage when breathing in, and the gas of on the other hand exhaling is not just discharged with filtering, causes the propagation of disease easily, that is to say, some current gauze masks that have the breather valve can only produce the protection nature to the wearer, can't disinfect the air of wearer's exhalation and disinfect.
For medical staff, the safety performance of the mask is very important, and for medical staff working for a long time, the air permeability of the mask is also more important, and although a common protective mask, such as a cotton mask or a medical surgical mask, has good air permeability and wearing comfort, for first-line medical staff working in high-risk wards, the protective safety performance of the mask is insufficient, so that the mask is not suitable for high-risk sick houses. Although the N95 mask has better protective performance, the air permeability of the mask is difficult to guarantee, the air impermeability of the mask can cause the medical staff to sweat, and the medical staff does not have the condition of wiping sweat at all in a long-term working state and a high-risk sick house. The existing cotton gauze mask and medical surgical mask can not be reused and have short service time. Although the N95 mask has a relatively long life, it has a very limited life and is very breathable.
