Description

A customizable respiratory protection nasal patch

technical field

The utility model relates to the technical field of respiratory protection articles, in particular to an individualized customizable respiratory protection nasal patch.

Background technique

With the decline of air quality, especially the emergence of hazy weather, many people will take respiratory protection measures (such as wearing masks, nasal masks, etc.). Its mechanism is mainly relying on human inhalation to force polluted air to filter through the cover, so that air particles with a certain particle size (such as PM2.5) are blocked outside the cover or adsorbed in the cover to avoid harmful air. The purpose of particulate matter entering the human respiratory tract.

At present, the masks on the market mainly include disposable simple masks, non-woven medical masks, 3M masks, etc., generally including a body and a lanyard. The body is made of filter material to filter the air inhaled by the human body and isolate various pollutants; hanging Cord-separated headband type or earband type. The main prevention objects of masks are polluted particles, PM2.5 particles, germs, molds, pollen and other allergens. Because the edge of the mask needs to fit the nose, face and chin of the person, an effective air filtration barrier can be constructed. However, in fact, the three-dimensional contour of each person's face is very different, and the user's nose and face are undulating, so that the edge of the mask cannot closely fit the surface of the nose and face, resulting in failure of protection. Despite improvements such as metal nose clips, beading, or sponge linings, a complete seal cannot be achieved. The article "Comprehensive evaluation of the protective effect of common self-priming filter masks" in the fifth issue of "Environmental and Occupational Medicine" in 2018 mentioned that the leakage of masks is directly related to the protective effect of masks, and domestically produced masks are still leaking. There is a large gap, the main reason may be that the mask does not match the face shape of the wearer. In addition, the mask of the prior art also has the following shortcomings:

1) The mask covers the nose and mouth, and it is impossible to drink or eat, which affects speech and communication. After wearing it for a long time, the inner layer of the mask is easy to breed bacteria due to the humidity and heat.

2) When the weather is cold, because the mask cannot be tightly attached to the nose and mouth, the exhaled water vapor will blur the glasses and affect the vision.

3) The headband or earband has the defect of being troublesome to wear, especially for women, hat wearers, glasses wearers, children, etc., it is troublesome to adjust, too tight will make the wearer very uncomfortable, too loose will lead to seal failure;

4) Poor comfort, the article "Only 20% of masks are haze-proof and comfortable" in "Legal Daily" on March 22, 2014 reported that the results of the comparison test of the protective performance of masks released by the Consumers Association and consumer rights protection organizations in 5 provinces and cities on the same day showed that : Among the 37 mask samples, there are only 9 samples that can achieve both good anti-haze effect and comfortable wearing, accounting for only 24%, less than a quarter. And because of the impact on aesthetics, many people do not wear masks indoors, so they cannot protect indoor PM2.5.

Due to various shortcomings of masks, nasal filter protection products such as "nasal masks, nasal plugs and nasal stickers" came into being. The advantages of its small size and its ability to use it without disturbing people's eating and talking do have enticing potential. However, at present, the nasal filter has not been widely used in the market, because there are still many deficiencies in the design and process of the current nasal filter. The primary disadvantage is that the nasal filter still has the same key technical defect as the mask, which is poor sealing performance. Then there are the following five problems:

1) Appearance problem: Existing similar products, such as nasal masks, are bulky and clumsy in appearance, making them difficult for everyone to accept;

2) Structural problem: the nasal mask of the prior art needs to fix the filter layer, and at the same time needs to be provided with various buckles, resulting in an overly complicated and cumbersome structure;

3) Problems in use: When using the nose mask, you have to hang a rope on the ear or use glasses to help the pressure, which is not reliable and troublesome;

4) Physiological problems: nasal congestion products must be inserted into the nostrils for use, which will lead to the formation of dust-proof voids after the growth of nasal hair is dislocated;

5) The appearance is different: the crescent-shaped filter material is used to protect the nasal cavity, because it is disgusting that the nostrils cannot be seen after pasting and using;

In the Chinese utility model patent application, the authorization announcement number and name are CN204073165U nasal filter patch, CN203315583U nasal mask, CN205626774U imitation nasal air filter, CN204684489U nasal mask, CN2481356Y disposable nasal mask, CN204352407U a kind of safety nose cover, CN206587298U A kind of air purifying nasal patch, CN204543321U self-adhesive self-priming filter type anti-particulate respirator, the common point of the above disclosed nasal patch (or nasal mask, etc.) is that the scope covers the entire nose, up to the bottom of the bridge of the nose, down to the nostrils and At the labial groove, from left and right to both sides of the nose wings, there are sticking materials on both sides of the nose wings, and filter modules such as air filter membranes are arranged at the nostrils. And they all have a common flaw, that is, there is no key technology to make the nose stick (or nose mask, etc.) completely fit the nose. When the user breathes, the air can easily enter and exit from the gap between the edge of the nose sticker (or the nose mask, etc.) and the surface of the nose, resulting in failure of the protection.
