Description

Bionic nasal cavity filtering device

Technical Field

The invention relates to the technical field of respiratory filters, in particular to a bionic nasal cavity filtering device.

Background

At present, with the rapid development of industrialization, the air breathed by human contains a plurality of waste gas particles, solid particles such as germs and dust, and the like, the tiny dust is less than 10 μm, especially PM2.5 particles can avoid nasal mucosa and nasal hair and the filtration of respiratory tract to reach the lung of human, thereby causing various respiratory tract diseases and causing serious harm to human body. Allergen particles floating in the air, such as pollen (10-50 μm) and the like, can be inhaled into the respiratory tract to cause allergic reactions. In order to avoid inhaling toxic and harmful substances, a common mode of people is to wear a mask, but the mask has the defects of large volume, inconvenient speaking, unsmooth breathing and the like; a bionic nasal cavity filter is a novel air filter, which is directly plugged into the nostrils when in use, collides with the inner blades of the cover body and the inner surface of the cover body under the influence of turbulence through inhalation particles, is captured by an allergen separating agent with strong force, is separated in the nasal plug and can not enter the nasal cavity. The perfect combination of the strong adhesion function of the allergen blocking agent, the low wind resistance value and the turbulent flow adsorption and sedimentation function of the bionic nasal cavity filtering device can greatly enhance the blocking function on the inhalation particles in the air, and the effect of preventing the particles from influencing the human health is achieved.

For example, the invention of patent No. CN209662475U discloses a nasal cavity filter, which comprises two shells inserted into the nasal cavity, a filter chamber disposed in the shell for filtering harmful dust and bacteria, and a fixing member disposed at the bottom of the filter chamber, wherein the shell comprises an upper shell and a lower shell connected with the upper shell through the filter chamber, and the filter chamber extends from the upper end of the upper shell to the lower end of the lower shell. Also, for example, the invention with patent number CN104338263A discloses a nasal air filter, which uses elastic nontoxic plastic as the shells, the two plastic shells are connected by a thin belt of the same material at the bottom, the shell contour simulates the shape of the nostril, a layer of anti-drop, sealing and flexible material is coated outside, the interior is a cylindrical cavity, the bottom of the cavity is provided with an air inlet filter layer, then an activated carbon chamber is arranged, and then a pollen filter layer, a PM2.5 filter I layer and a PM2.5 filter II layer are sequentially arranged, and the upper end of the cavity is a purified air outlet. The two nasal filters disclosed above have some disadvantages in use: firstly, in order to achieve a better filtering effect, a filtering layer needs to be arranged in a filtering cavity, and the traditional filtering layer is columnar, so that the filtering effect is excellent, but the breathing resistance is easy to be large, and the breathing of a wearer is unsmooth; secondly, when the filtering layer in the nasal cavity filter is reduced in filtering effect after being used for a long time, the filtering layer in the filtering cavity is quickly replaced; thirdly, the existing nasal cavity filter design does not conform to the principle of human engineering, and is easy to cause discomfort after being worn for a long time; fourthly, the filtering function of the existing nasal cavity filter is single, and the effect of simply filtering the respiratory air can be achieved.

Therefore, there is a need to provide a new bionic nasal cavity filtering device to solve the above technical problems.

Disclosure of Invention

The technical problem to be solved by the invention is to provide a bionic nasal cavity filtering device which is convenient to use and simple to operate and can enhance the effect of blocking inhalation and particulate matters in air.

In order to solve the technical problem, the bionic nasal cavity filtering device provided by the invention comprises: a connecting bridge and two filter nasal plug assemblies.

Preferably, the connecting bridge and the filtering type nasal plug assembly are made of soft materials, and the soft materials comprise silica gel, rubber and medical plastics.

Preferably, the surfaces of the long inner leaf, the short inner leaf and the cover body are coated with an allergen barrier agent.

Preferably, the filter type nasal plug component is manufactured by adopting a bionics principle and imitating vibrissa, and is used for disturbing airflow entering a nasal cavity, forming turbulence, settling particles and reducing air resistance.

Compared with the related art, the bionic nasal cavity filtering device provided by the invention has the following beneficial effects:

1) the nasal hair plays a first barrier role in the nasal cavity filtration. After air enters the nostrils, the inlet part is narrow, the inner cavity wall of the nostrils is irregular, and the nose hair faces the forward and outward direction, so that like a forest, the air flow is disturbed to form turbulent flow and roundabout air flow, the frictional resistance of particulate matters is increased, and larger inhalable particulate matters in the air are settled at the nostrils. The nose hair plays a role in filtering and settling particles, does not increase air resistance, and causes dyspnea. According to the characteristics of the vibrissa, the novel bionic nasal cavity filtering device adopts the bionics principle, imitates the function of the vibrissa, disturbs the airflow entering the nasal cavity, forms turbulence, settles the particulate matter, and when effectively settling the particulate matter, the air resistance is reduced as much as possible.

2) The allergen blocking agent is made of a bioactive-free organosilicon material, has strong adhesion, and can adhere to allergens and block allergic reactions through high-adhesion physical characteristics.

3) Coating allergen separating agent inside novel bionical nasal cavity filter equipment, inhalant granule is under the influence of torrent, collides with novel bionical nasal cavity filter equipment inner leaf to by allergen separating agent powerful catch, by the separation inside filter equipment, can't get into the nasal cavity.

4) The powerful adhesion effect of allergen blocking agent, novel bionical nasal cavity filter equipment low wind resistance value and torrent adsorb the effect of subsiding, and the perfect combination of the two will greatly strengthen the barrier effect to inhalation particulate matter in the air, reaches the influence of prevention particulate matter to human health.
