Description

Detachable photosensitizer medical mask

Technical Field

The utility model relates to a gauze mask field, in particular to medical gauze mask of detachable photosensitizer

Background

The mask is an important defense line for preventing respiratory infectious diseases, and can effectively block the transmission of respiratory droplets under the background of the current pandemic of new coronary pneumonia, thereby reducing the infection risk of novel coronavirus. First, the protective effect is unsatisfactory, and as disclosed in prior art 1 (application/patent No. CN201620220694.4 publication/publication No. CN205597196U), a mask in which a meltblown fabric layer adsorbs harmful gases and substances in air filtered by activated carbon, which does not solve the contradiction between the improvement of virus filtration efficiency and the reduction of respiratory resistance, the mechanical filtration function and the virus adsorption function should be considered to be organically combined, so that the mask has excellent virus adsorption and inactivation functions in addition to good mechanical barrier performance. Secondly, as disclosed in prior patent 2 (application/patent No. CN201020104727.1 publication/announcement No. CN201709443U), a mask adhered with a pressure sensitive adhesive tape has viscosity, and can be adhered to the nose bridge of a medical worker, but the mask has poor facial fitting effect, insufficiently tight nasal sealing, and no ability to completely block droplets, and also causes no filtered air to be sucked from both sides of the nose bridge, resulting in poor protective effect, and hardly playing a protective role in the period of high incidence of pathogenic microorganism infectious diseases. And has low comfortable feeling after long-term wearing. In view of the high demand for an epidemic prevention effect against the background of the pandemic of new coronary pneumonia, prior art 3 (application/patent No. CN201820213454.0 publication/publication No. CN208490929U) discloses a flat type mask, which does not consider that the main component of the spray is water, and that viruses may remain on the mask and transfer between fibers after the water evaporates. Along with the continuous progress of the breathing action of the human body, the virus can be transferred to the inner layer of the mask and enters the organism by contacting with the mouth and the nose, and the protection effect is not ideal.

For medical masks, the antibacterial and antiviral effects of the material are also important. The photosensitizer has good bactericidal effect and potential antiviral effect, and has the advantages of stable structure, high activity, low toxicity, high safety and strong antiviral ability. An antibacterial polymer film is disclosed in prior art 4 (publication No. CN112585227A), which includes a base layer and a photosensitizer dispersed in the base layer, the base layer being a polymer resin, and the photosensitizer being at least one of a porphin compound, a porphyrin compound, a chlorin compound, a bacteriochlorin compound, a phthalocyanine compound, a naphthalocyanine compound, and 5-aminolevulinate. The antibacterial polymer film disclosed by the patent has excellent antibacterial and antiviral effects and has a wide application prospect.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome the not enough of prior art, provide a medical gauze mask of detachable photosensitizer that antibiotic antiviral effect is strong.

Furthermore, a buffering sponge cushion is arranged at the position, corresponding to the aluminum strip, on the inner side of the medical gauze skin-friendly layer.

Further, the aluminum strips and the buffering sponge cushion are consistent in shape and size.

Further, the length of the buffering sponge cushion is 7-11cmx0.2-0.5m, preferably 9.5cm, and the width is 0.3 cm.

The buffering foam-rubber cushion reduces discomfort caused by fixing the aluminum shaping strip, and improves comfort level when the mask is worn.

Further, a drying bag is arranged on the inner side of the medical gauze skin-friendly layer.

Further, the effective drying component in the drying bag is an anhydrous calcium chloride drying agent.

Further, the size of the dry pack was 4 cmx1cmx0.2cm.

Furthermore, the number of the drying bags is two, and the drying bags are symmetrically arranged at two ends of the inner side of the skin-friendly layer of the medical gauze.

The steam in the dry package can adsorb the expired gas, reduces the phenomenon that the gas that appears exhaling blows to leading to the fog on glasses through the gap of nose wing department, has improved the comfort level when the people who wears glasses wears this gauze mask. And the aluminum strip and the buffer sponge cushion can bear the pressure of a part of mask and the dry bag of anhydrous calcium chloride powder, and the mask can be perfectly attached to the face to play a role in fixing.

Further, the gauze mask string rope is ear-loop type or pullover type, just the gauze mask string rope is the elastic webbing.

Further, the length of the mask hanging rope is as follows: 15-20cmx3-5m, preferably, the length is 16cm, and the width is 4 mm.

The mask hanging rope has elasticity, does not feel strange after being worn for a long time, is suitable for any face shape, and meets the width and the length of the face shape of all users.
