Abstract

The invention discloses a high-ventilation breathing filter placed in the nasal cavities. The breathing filter is characterized by being mainly composed of a pair of inner cages, a pair of filter bags and a pair of outer cages. When the breathing filter is used, the filter bags are arranged on the inner cages in a sleeving manner, and then the filter bags and the inner cages are placed into the outer cages together. The combined breathing filter is inserted into the nasal cavity, and then a user can breathe freely. As the skeleton structures of the outer cages stretch the inner walls of the nasal cavities open, the effective filtration area loss caused by large-area contact between the filter bags and the inner walls of the nasal cavities is avoided. Accordingly, the breathing filter is high in effective ventilation capacity and good in wearing stability and comfort performance. By using the breathing filter, dust, pollen and pathogenic microorganisms can be effectively prevented from entering the respiration system. Meanwhile, the influence on the attractiveness and the function of the mouth is avoided, and the breathing filter can care health of the respiration system of a wearer on any occasion all time.

Description

A kind of high aeration nasal-cavity-embedded breathing circuit filter

Technical field

The invention belongs to respiration filtering device, especially belong to nasal-cavity-embedded respiration filtering device.

Background technology

Owing to air being suspended with substantial amounts of dust, pollen and pathogenic microorganism etc., thus the respiratory system to people, or even The health of whole body brings serious threat.If can effectively prevent dust and pathogenic bacteria to be inhaled into respiratory system, to the mankind Healthy tool be of great significance.At present, the instrument being mainly used to filter dust in air, pollen and pathogen etc. is mouth Cover.Due to traditional mask also exist that wearing comfort is poor, cost high, after C&S, contaminated chance is big etc. Shortcomings, therefore, it uses a lot of limitation.When polluter is not the most serious at heat especially, just wear mask Seem the most uncomfortable, and unnecessarily.Additionally, at the public places such as office, meeting room and classroom, air pollution ratio More serious, need to carry out suitable protection to oneself breathing, but wear masks and seem less suitable, at this moment, be preferably formed with nose Chamber built-in breathing filter replaces.

Nasal-cavity-embedded breathes wearing of filter, neither affects the attractive in appearance of wearer and courtesy, nor affects on wearer's mouth The Function of bar, it may be said that words and diet.Although there being these advantages, but the simply stop of nasal cavity built-in breathing filter before this In the conceptual phase, the most successful product comes out.With regard to its reason, mainly due to the limited space of nasal cavity, current is built-in Formula filter constructions is complicated, causes ventilatory effect smooth, has sensation of asphyxia, and wearing comfort is the most very poor with the stability worn.Cause This, the nasal-cavity-embedded breathing circuit filter developing a kind of high aeration is the most necessary and urgent.

Summary of the invention

The invention discloses " a kind of high aeration nasal-cavity-embedded breathing circuit filter ", it is characterised in that: main by a pair External cage (Fig. 3) three part of interior cage (Fig. 1), a pair filter bag (Fig. 2) and one forms.Wherein, within interior cage is placed in filter bag, will filter Bag struts, and is together placed among outer cage, is combined into complete high aeration nasal-cavity-embedded breathing circuit filter (Fig. 4).One Internally cage is mainly made up of 1 interior cage wide for 2 ~ 4mm contact band (1) two symmetrical interior cage of connection.Interior basket structure mainly includes 1 On the interior cage that root 2 ~ 5mm is wide foundation ring (2), foundation ring under 3 ~ 5 interior cage support bars (3) wide for 1 ~ 3mm and 1 interior cage wide for 2 ~ 5mm (4).The interior a length of 5 ~ 15mm of cage support bar, links together foundation ring on interior cage with foundation ring under interior cage.Filter bag is soft by breathability Tough material is made, and in pocket-like, is the filter bag body (7) of 5 ~ 15 mm and straight including the filter pocket mouths (6) of a diameter of 5 ~ 18 mm, the length of side Footpath is at the bottom of the filter bag that 4 ~ 15 mm seal (8), and a pair filter bag carries (5) at filter pocket mouths adjacent through 1 filter bag wide for 2 ~ 4mm contact Connect together.Outer cage mainly includes foundation ring (10) on 1 outer cage wide for 2 ~ 5mm, 2 ~ 5 outer cage cross-brace bars wide for 1 ~ 4mm (11), foundation ring (13) under 4 ~ 6 outer cages longitudinal bracing bar (12) wide for 1 ~ 4mm and 1 outer cage wide for 2 ~ 5mm, two outer cages exist Connect together through 1 outer cage contact band (9) at foundation ring on outer cage and constitute an external cage.Outer cage longitudinal bracing bar a length of 5 ~ 15 mm。

The material of all such use, equal avirulence, nasal membrane is not had sensitization and zest yet, and glues at nasal cavity Stable in properties in liquid, it is unlikely to deform and dissolves.

In use, filter bag (Fig. 2) is enclosed within interior cage (Fig. 1) outward, and within putting into outer cage (Fig. 3) together.To combine The two ends of the built-in breathing circuit filter of high aeration nasal cavity (Fig. 4) fill in two nostrils respectively within, contact band is outside nasal septum Side, prevents filter to be inhaled into, and is easy to take out filter.Owing to nasal cavity inwall is strutted by outer cage (Fig. 3), it is to avoid filter bag (Fig. 2) Have lost effective filtration area because abutting directly on nasal cavity inwall, thus substantially increase effective ventilatory volume.
