specific Embodiment approach 1

[0024] Specific embodiment 1: This embodiment describes a protective nasal plug, which is made of porous PDMS material, such as Figure 6 shown.

specific Embodiment approach 2

[0025] Specific embodiment two: a preparation method for protecting nasal congestion described in specific embodiment one, such as Figure 4 As shown, the method steps are as follows:

[0026] Step 1: Pour sucrose evenly into the nasal plug mold to reach the height of the sucrose, and then compact and smooth it; specifically, the structure of the nasal plug mold can be designed with reference to the earplug mold, and there is no need to make a unified limit, as long as the shape of the prepared nasal plug can be ensured It is enough to plug the nostrils; the height of the sucrose height line does not need to be uniformly limited, and can be adjusted appropriately according to the length of the nasal congestion into the nostrils;

[0027] Step 2: Pour the prepared PDMS into the mold. The highest liquid level of PDMS cannot be higher than the lowest point of sucrose; in this step, the highest liquid level of PDMS cannot be higher than the lowest point of sucrose. After flowing ...

specific Embodiment approach 3

[0030] Specific embodiment three: a preparation method for protecting nasal congestion described in specific embodiment two, in step two, the prepared PDMS is obtained by pouring PDMS glue and curing agent into a container according to a mass ratio of 10:1 and stirring well of.

Abstract

The invention discloses a protective nose plug and a manufacturing method thereof, belongs to the technical field of medical sanitary products, and aims to solve the problems that an existing mask cannot actively adsorb viruses and dust particles, and is complex in manufacturing device and process. The protective nose plug is made of a porous PDMS material. Cane sugar is uniformly poured into a nose plug mold, and then compacted and flattened until the cane sugar reaches a cane sugar height scale line; the prepared PDMS is poured into the mold, wherein the highest liquid level of the PDMS cannot be higher than the lowest position of cane sugar; the mold together with the substances therein are solidified; and the solidified nose plug is taken out from the mold and then placed in boiled water or directly heated so that the inside cane sugar can flow out of the nose plug to form a porous structure, and finally the nose plug is cleaned with clear water and dried by blowing compressed air.According to the protective nose plug and the manufacturing method thereof, the manufacturing method is simple and easy to operate, and the protective nose plug can be homemade as well as industrialmass production; a filter element of the PDMS material can be repeatedly cleaned and recycled for multiple times, so that the cost is saved; and a nose plug cover is tightly attached to a nose of a human body, and only covers the nose not a whole face.

Description

technical field [0001] The invention belongs to the technical field of medical and sanitary products, and in particular relates to a protective nasal congestion and a preparation method thereof, which can be used for anti-virus, anti-pollution particles, anti-smog and the like. Background technique [0002] A mask is a sanitary product, generally refers to a device worn on the mouth and nose to filter the air entering the mouth and nose to block harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose, made of gauze or paper. The mask has a certain filtering effect on the air that enters the lungs. When respiratory infectious diseases are prevalent, when working in a polluted environment such as dust, wearing a mask has a protective and preventive effect. [0003] However, most of the existing anti-virus and anti-smog masks are made of several layers of fabrics, such as multi-layer gauze or non-woven fabrics and fused fabrics, which are sewed ...
