A gel that blocks pm2.5 and other nasal allergens

Abstract

The invention provides a gel for blocking PM2.5 or other nasal allergens in the air. In addition to purified water, it includes the following components in weight ratio: 0.2%-20% polyquaternium salt, cationic guar gum : 0.1% to 10%. The invention also provides the preparation method and application of the gel. In order to conveniently and effectively block PM2.5 particles in the air and other nasal allergens from entering the human respiratory system, the present invention provides a gel product with cationic polyquaternium salt and guar gum as the main raw materials for the first time. Apply it around the nose of the user, and generate an electrostatic field like an air filter around the nasal passages through various cations, which can effectively prevent particulate matter in the air (especially PM2.5) from entering the nasal passages, lungs and other respiratory systems. While blocking PM2.5, it can also block other nasal allergens in the air: grass clippings, pollen, dust mites, animal and plant dander, etc. from entering the respiratory system, avoiding nasal allergies, and protecting the respiratory system, cardiopulmonary function and other health.

Description

technical field [0001] The invention relates to a gel for blocking PM2.5 or other nasal allergens in the air. Background technique [0002] In recent years, most cities in China have suffered serious air pollution and frequent smog. Large particles in the air are easily intercepted by the nasal cavity, throat, and trachea, or excreted through the movement of fluff. PM2.5 is fine particles. Inhaled by the respiratory tract, it will be deposited in the alveoli of the human body, and then dissolve into the blood, causing blood poisoning, which can easily reach the depths of the lungs, causing damage to the respiratory system and cardiovascular system, causing respiratory tract irritation, coughing, dyspnea, and aggravating asthma Attack, arrhythmia induced heart disease, etc., so the PM2.5 index has become an important index for measuring and controlling the degree of air pollution. [0003] At present, most people in China generally use masks to deal with PM2.5 pollution, but...

AI Technical Summary

Problems solved by technology

[0003] At present, most people in China generally use masks to deal with PM2.5 pollution, but general masks cannot prevent inhalable particulate matter. Medical masks are mainly for respirable particulate matter above PM3, and for respirable particulate matter below PM2.5. The effect is small; the effect of PM2.5 masks is the best, and the efficiency of filtering PM2.5 fine particles is greater than 95%, but its disadvantages are also particularly obvious: high respiratory impedance, not suitable for young children, pregnant women, heart or respiratory system difficulties People with sensitive skin and those with sensitive skin; it is not recommended to use it in places with poor air circulation or indoors; it is not recommended to wear a mask for a long time, otherwise the nasal mucosa will become fragile and lose the original physiological function of the nasal cavity; the outer layer of the mask is easily contaminated with dirt and bacteria , the inner layer is prone to bacteria and needs to be cleaned every day, and the one-time one needs to be replaced every day, and the cost is high
