Gel capable of preventing PM2.5 and other nasal allergens

Abstract

The invention provides a gel capable of preventing PM2.5 or other nasal allergens in air. The gel comprises the following components in percentage by weight: purified water, 0.2%-20% of polyquaternary salt and 0.1%-10% of cationic guar gum. The invention also provides a preparation method and use of the gel. In order to conveniently and effectively block PM2.5 particulate matters and other nasal allergens in air from entering the human respiratory system, a gel product prepared from cationic substances, namely, polyquaternary salt and guar gum serving main raw materials is firstly provided and is applied at the periphery of user nose, an air filtration screen-like electrostatic field is produced at the periphery of a nasal passage by virtue of various cations, particulate matter (especially PM2.5) in air can be effectively prevented from entering respiratory systems such as the nasal passages and lungs, PM2.5 is blocked and meanwhile, other nasal allergens in air such as turfgrass clippings, pollen, dust mites, animal and plant dander can also be blocked from entering the human respiratory system, the nasal allergy is avoided and the physical health of respiratory system, heart and lung functions and the like are protected.

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
