Nasal mask with air exhausting valve

Abstract

The invention provides a nasal mask with an air exhausting valve and relates to the technical field of medical equipment. The nasal mask with the air exhausting valve comprises a nasal mask main body,a one-way air exhausting valve, a filtering component and a fixing component, wherein the nasal mask body is used for covering the nose and is provided with an air cavity capable of being communicated with nostrils; the one-way air exhausting valve is arranged on one side of the nasal mask main body and is communicated with the air cavity; the filtering component is mounted on the nasal mask body; the air cavity is provided with a bottom opening; the filtering component covers the bottom opening; and the fixing component is connected with the nasal mask body and is used for fixing the nasal mask body on the face. According to the nasal mask with the air exhausting valve, the nose mask body only covers the nose; the volume of a filtering material can be reduced; the materials are greatly saved; the resource waste is reduced; through the one-way air exhausting valve, the fresh air inhalation flow and the air exhalation speed are greatly increased; the one-way air exhausting valve is used for replacing melt-blown cloth with excessively closed density; and the structural defects such as long-term oxygen deficit and the like caused by expiratory dyspnea of a mask composed of the melt-blown cloth are greatly improved.

Description

technical field [0001] The present application relates to the technical field of medical equipment, in particular to a nasal mask provided with an exhaust valve. Background technique [0002] As human beings are attacked by bacteria and viruses more frequently and more extensively and complexly, because of the increasingly frequent flow of people under globalization, the spread of bacteria and viruses spreads rapidly globally through human-to-human transmission. Masks are used to prevent human-to-human transmission The role of the traditional effective tool of communication is becoming more and more important. [0003] However, the use of masks, in addition to the ugly appearance, makes people miserable in hot summer, especially in tropical countries, because of the unusual sweltering heat. In addition, face recognition high-tech technology is automatically invalidated, and masks are used when gathering in public places such as restaurants, restaurants, and dining halls, es...

AI Technical Summary

Problems solved by technology

Long-term lack of oxygen caused by wearing a mask for a long time will not only cause lung and respiratory diseases and permanent brain damage, but also make it difficult to concentrate because of distraction in class, which will inevitably lead to a decline in academic performance, and the work efficiency of the same enterprise will be greatly reduced.

[0006] Nearly a hundred years of mask history, its extremely wasteful disposable anti-virus design, all of the functions given are temporary and short-lived "expedient measures", completely unable to deal with the virus that will be inseparable from human beings. The tradition of killing one thousand enemies and destroying eight hundred is backward, the air permeability is not satisfactory, and the traditional mask full of omissions has been proved to be out of date.
