Nose breathing filter

Abstract

The invention discloses a nose breathing filter used for improving the technical field of breathing. The nose breathing filter comprises an arched connecting support. The bottom of the connecting support is opened to form a clamping part. Cylindrical plug-in parts are arranged on the two sides of the connecting support. An airflow channel and a filtering membrane capable of being opened or closed in the airflow channel are arranged in the plug-in part on each side. Each airflow channel is provided with a suction opening and an exhalation opening. Each exhalation opening is provided with an evaporation membrane. A liquid storing cavity is formed in the connecting support. The outer wall of the connecting support is provided with micro holes communicating with the liquid storing cavity. The evaporation membranes are connected with the micro holes. The nose breathing filter makes little contact with nose mucosa, has a little influence on nose physiological environment, and can have an auxiliary treatment effect on trachea while reducing exhaling resistance to the greatest extent.

Description

technical field [0001] The invention relates to the field of breathing medical equipment, in particular to a nasal breathing filter. Background technique [0002] With the increasing air pollution index, especially in urban air, the emission of soot-based air pollutants (the pollutants include sulfur dioxide, carbon dioxide and soot), vehicle exhaust, and toxic gases from chemical plants have been exhausted. Beyond the natural self-purification ability, it is threatening the health of the human respiratory system. In addition, with the increase of air pollution, people with respiratory diseases and airway hyperresponsiveness urgently need to find a daily prevention and care method that can reduce the inhalation of air irritants and have the effect of airway nebulized drug delivery. Masks have become the most commonly used cheap respiratory protection equipment, but wearing masks hinders face-to-face communication, and most of them cannot be reused, and have little effect on...

AI Technical Summary

Problems solved by technology

Masks have become the most commonly used cheap respiratory protection equipment, but wearing masks hinders face-to-face communication, and most of them cannot be reused, and have little effect on toxic pollutants. In view of this situation, CN 202191615U discloses a micro-economic The nasal breathing filter is composed of front and rear rings arranged in parallel, connecting rods and struts, and several groups of three-blade wheel-shaped sieves distributed along the axial direction of the connecting rods, relying on the storage liquid in dense micropores on the aforementioned components to generate specific adsorption Due to the design of the wheel-shaped sieve with a micro-tube structure, the contact area with the inhaled air is very small, so that the filtration efficiency is limited, and the sieve leaf activity is poor, and the resistance generated during exhalation will easily cause discomfort to the user.

In addition, CN103349818A is composed of chemical polyester fiber and cotton mixed sections, which is a pair of nasal cavity packing body, so as to filter out fine particles in the air, and this design is a columnar filling, which is easy to cause nasal discomfort of the user after wearing, and at the same time Causes large expiratory resistance and great interference with the physiological environment in the nasal cavity

In addition, the design is not conducive to repeated use, and there is no fixing device, so it is easy to fall off due to exhalation or sneezing

[0003] Not only that, the above-mentioned technology can only play a filtering role, but has no therapeutic effect on some respiratory diseases, resulting in a single function of masks and filters
