Anti-suffocation mask device for infectious diseases of pneumology department

Abstract

The invention discloses an anti-suffocation mask device for infectious diseases of the pneumology department, which relates to the technical field of medical equipment. The mask device comprises an airtight mask body; a transition air cavity and an air cavity A which are integrally formed are formed in the front end of the mask body. Air cavities B are further connected to the two sides of the front portion of the transition air cavity and / or the two sides of the rear portion of the air cavity A. Replaceable filter discs are arranged at the front end of the air cavity A and the outer side endsof the air cavities B. A first one-way air valve is further arranged on the surface of the inner wall of the air cavity A and located between the filter discs of the air cavity A and the inner side ends of the air cavity B. A second one-way valve is further arranged on the surface of the inner wall of the air cavity B and located between the outer side end and the inner side end of the air cavityB; one of the first one-way valve and the second one-way valve is used for limiting air to flow out of the mask body, and the other one is used for limiting air to flow into the mask body. The mask can effectively relieve oppressed symptoms of a wearer, and the mask is provided with the air bag which can replace the filter disc and can be automatically adjusted, so that the mask has a relativelystrong auxiliary effect on anti-epidemic first-line personnel.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an anti-breathing mask device for respiratory infectious diseases. Background technique [0002] In addition to home isolation, masks, as traditional disease prevention devices, have become very scarce. At present, masks with preventive effects recognized by the public include medical disposable masks, medical surgical masks, medical N95 masks, and medical KN95 masks. Most of the materials are composed of waterproof layer, filter layer, and skin-friendly layer. Although they can play a certain role in disease prevention, there are still the following defects: [0003] 1. When the mask is worn, it is difficult to breathe due to the limited space in the cavity of the mask. Wearing it for a long time will cause lung discomfort or even lung damage. Therefore, ordinary masks need to be worn for 2-4 hours to remove, let alone Wearing a mask for strenuous exercise [0004]...

AI Technical Summary

Problems solved by technology

[0003] 1. When the mask is worn, it is difficult to breathe due to the limited space in the cavity of the mask. Wearing it for a long time will cause lung discomfort or even lung damage. Therefore, ordinary masks need to be worn for 2-4 hours to remove, let alone Wearing a mask for strenuous exercise

[0004] 2. The reason for suffocation is that the existing masks have a narrow breathing space and poor air permeability. The exhaust gas exhaled by the human body is accumulated in the mask, and the gas exchange with the outside world is slow, resulting in a significant drop in the amount of oxygen required for human breathing; and because The defect of the existing technology is that breathing and inhalation share the same inner cavity of the mask, and the inherently narrow space cannot meet the needs of gas shunt exchange, resulting in exhaled carbon dioxide being re-inhaled into the lungs, causing extreme discomfort after a long time;

[0005] 3. Because the air that people breathe out contains a lot of water, the existing masks have limited waterproof performance only by the inner skin-friendly layer, and will soon be wetted, and the wetted water will enter the filter layer—usually Melt blown cloth with static electricity - and moisture will cause the filter layer to fail quickly, thus affecting the protective effect;

[0006] 4. In fact, the masks worn by many people are reused many times. Their formal significance is greater than their practical significance, and the protective effect is minimal. How to improve the production efficiency of masks, save costs and meet needs has become an urgent problem to be solved.
