Description

Comfortable protective mask capable of preventing fog of goggles from being generated and silica gel pad
Technical Field
The utility model belongs to the field of medical equipment, a medical protective articles for use is related to, concretely relates to travelling comfort protective facial mask and silica gel pad that can prevent goggles fog to produce.
Background
The mask is used as a sanitary protective article and is used in medical treatment, epidemic prevention and dust prevention. As is known, the mask can filter air entering a nasal cavity when being worn, so that dust, virus, spray and the like are prevented from invading a human body through the nasal cavity, and the mask has a better protective effect.
For medical personnel at epidemic prevention front line, wearing protective mask such as N95 all the time is the first protective measure during longer diagnosis and treatment work, however, in order to improve the protective effect, need press from both sides tight gauze mask nose through plasticity nose clamp, but the fact proves that the effect of nose clamp alone can't prevent exhaling gas upwards to escape, get into the goggles, wear for a long time and can cause the formation fog, steam accumulation in the goggles, seriously influence the sight. In addition, wear protective mask in-process for a long time at medical personnel, on the one hand because the oppression of nose clip, on the other hand wears the goggles and presses on the gauze mask nose clip constantly, causes the problem of nose facial skin indentation, wearing and tearing very easily like this.
In order to solve the above problems, the following solutions are currently retrieved:
CN201720596180.3 "antifog haze antifog gas gauze mask" discloses at gauze mask body top design the middle silica gel strip of establishing the notch for the laminating blocks that expired gas rises on the alar nose. However, in order to achieve an ideal sealing effect, the silica gel strip needs to have enough thickness to fill the gaps among the mask body, the periphery of the nose and the cheeks, so that the weight of the silica gel strip is inevitably increased.
CN201220006762.9 "anti-fogging mask" discloses that two triangular convex pads are symmetrically arranged on the inner side of the mask main body, and are located on two sides of the nose wing when in use. The gaps between the mask and the two sides of the nose wing can be blocked only to a certain extent by the aid of the design, the sealing effect is still to be enhanced, the contact area between the protruding pad and the skin is increased by the aid of the triangular design, friction between the protruding pad and the skin is increased, and the comfort level is poor when the mask is worn for a long time.
CN201120371921.0 "a novel anti-mist mask" discloses that two symmetrical triangular pyramid shaped nasal protrusions are arranged in the middle of the mask, and in the use state, the nose is located between the two nasal protrusions to achieve the effect of blocking the air flow. However, this design does not achieve the desired effect due to individual variability in the nasal morphology.
CN201821662959.1 "medical antifog gas gauze mask" discloses that it is fixed in the middle part of gauze mask body upper end to be equipped with the nose and press from both sides the metal strip, and matter is hard, compares with materials such as silica gel, and the metal strip causes great pressure to nose face skin, and it is relatively poor to wear the travelling comfort for a long time.
Therefore, there is a need for a comfortable protective mask that prevents the generation of fog from the goggles and reduces the skin abrasion, and that is better suited for clinical use.
