Instantly sticking type nasal mask

Abstract

An instantly sticking type nasal mask comprises a filtering basic layer and a stickup layer. The stickup layer is in a ring shape and is fixed on the edge of the filtering basic layer; the middle of the filtering basic layer is provided with wrinkles; a ridge line formed by the wrinkles is provided with an elastic gap. The stickup layer of the instantly sticking type nasal mask is in the ring shape corresponding to a nasal tip, nasal alar ridge lines on the two sides of a nose and a nasolabial line, the stickup area of a nasal columellar is omitted, and the obstruction of the stickup area to a respiratory airflow is reduced. A filtering area is provided with the wrinkles, the wrinkles increase the superficial area of the filtering basic layer and increase the integral breathing area, and therefore the breathing area is larger than the sectional area of nostrils. The ridge line of the wrinkles is provided with the elastic gap, when expiration is carried out by a user, the elastic gap is pushed by the airflow to be opened, the airflow breathed out can be directly exhausted without filtered, the passing speed of the airflow is increased, and the breathing smooth degree of the user is improved. When the breathing is still, the elastic gap is automatically closed due to the elastic action of materials themselves. When inspiration is carried out, the elastic gap generates opposite direction movement because the bevels on the two sides of the gap are extruded by the inwards airflow, the closing is more compact, and accordingly, the externally polluted air can be avoided from being directly breathed in by a human body through the elastic gap.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an instant nasal mask. Background technique [0002] Nowadays, the problem of air pollution is becoming more and more severe, and the incidence of human respiratory diseases is on the rise. In a relatively polluted atmospheric environment, strengthening personal protection, preventing pollutants from invading the respiratory tract, and protecting human health are one of the important research topics for relevant technical personnel from all over the world. [0003] A kind of nasal mask, or nasal patch, has appeared at present, is a kind of small and exquisite, convenient personal respiratory protective equipment. However, the various nasal masks currently on the market, due to the limitation of their own small size, generally have the problem of small filter material area and poor ventilation effect. The ventilation aperture of some nasal masks is even smaller than the cross-secti...

Problems solved by technology

However, the various nasal masks currently on the market, due to the limitation of their own small size, generally have the problem of small filter material area and poor ventilation effect. The ventilation aperture of some nasal masks is even smaller than the cross-sectional area of ​​the nostrils, making breathing The resistance increases and the ventilation volume decreases, causing the user to breathe poorly and feel stuffy, which affects the use effect and thus hinders the popularization and application of the nasal mask
