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.

In some embodiments, α, β, γ are equal.

In some embodiments, α, β, and γ are all 45 °.

When using, the silica gel pad of "M" type can play the air current guide effect, and the air current of nasal part exhalation moves upwards along the outside of the fourth inflection portion (the inboard wainscot of fourth inflection portion), at the inflection portion, changes the air current direction and turns over downwards, has avoided causing the goggles problem of hazing through the upper edge of the gauze mask effusion. In addition, the "M" shape is bent and angled to support each other, forming a silicone pad with a certain volume to fill the gap between the mask and the nose. Further, different from the traditional silica gel strip-shaped design, the M-shaped design can effectively reduce the weight of the silica gel pad, so that the pressure and friction on the skin are reduced, skin indentation and wound are avoided in the long-term wearing process, and the comfort is improved.

Additionally, the utility model discloses a silica gel pad, except can being used to gauze mask body inboard, this "M" type silica gel pad also can be used to between goggles and the face, plays the buffering, reduces the effect of pressure, reduces and wears the wound of goggles to skin.

In some embodiments, the fourth folded portion 34 has a width greater than any of the first folded portion 31, the second folded portion 32, and the third folded portion 33.

The fourth reverse folding part 34 has a width of 10-40 mm and a thickness of 0.2-1.0 mm.

In a more preferred embodiment, the width of the first reverse folding part is 15mm, the width of the second reverse folding part is 10mm, the width of the third reverse folding part is 10mm, the width of the fourth reverse folding part is 25mm, and the thicknesses of the first reverse folding part, the second reverse folding part, the third reverse folding part and the fourth reverse folding part are all 0.5 mm.

The utility model discloses a protective mask wearing mode is for wearing gauze mask earlier, and the adjustment silica gel pad then takes the goggles. The utility model discloses a protection mask's antifog principle, as shown in fig. 4, the hot gas flow of wearing person's nasal part exhalation upwards loss, form the packing force towards the nose portion to the reverse folding portion of fourth, ascending hot gas flow meets reverse folding portion turn the head downwards, discharges from the gauze mask lower part, has avoided wearing person's goggles to fog, influences the person's of wearing sight.

To sum up, the utility model discloses a "M" type is turned over and is rolled over buffering silica gel pad and play four main actions: the nose clip has the advantages that firstly, the nose clip has an elastic shaping function and can replace a plastic nose clip to adapt to the shapes of the nose and the face of different people; secondly, the indentation and the friction of the mask to the skin are buffered and reduced; thirdly, the silica gel pad is adsorbed on the nasal part to obtain a good sealing effect, so that the exhaled gas is prevented from flowing upwards; fourthly, the silica gel pad seals the edge of the upper part of the protective mask, so that gas is mainly discharged from the lower part, and the protective mask can not be fogged when in use. The utility model provides a protective facial mask can not only prevent the goggles and fog, can also improve the travelling comfort that the gauze mask wore, is particularly useful for medical personnel and uses.

While the present invention has been described in detail with reference to the preferred embodiments thereof, it should be understood that the above description should not be taken as limiting the present invention. Numerous modifications and alterations to the present invention will become apparent to those skilled in the art upon reading the foregoing description. Accordingly, the scope of the invention should be limited only by the attached claims.
