Prevent atomizing device of aerosol pollution

Technical Field

The utility model belongs to the technical field of medical atomizing, concretely relates to prevent atomizing device of aerosol pollution.

Background

The action principle of aerosol inhalation therapy: aerosol inhalation therapy mainly refers to aerosol (aerosol refers to tiny solid or liquid particles suspended in air) inhalation therapy, and is characterized in that a bronchus dilator, antibiotics or antifungal drugs and the like are dispersed into tiny fog drops or particles by an atomization device, the tiny fog drops or particles are suspended in air to be prepared into aerosol, and the aerosol is inhaled into an air passage and lungs through an oral cavity, a nasal cavity or an air pipe in a smoke or fog mode, and of course, a tracheotomy tube is included, so that the purposes of cleaning the air passage, humidifying the air passage, performing local treatment and performing whole-body treatment are achieved. Is a therapeutic means for treating lung diseases or delaying the symptoms of the respiratory system. However, there are drawbacks in the aerosol inhalation therapy treatment for the treatment of new coronary pneumonia: the new Coronavirus Pneumonia (new coronary Pneumonia, Novel corona aventurus Pneumonia, NCP) is abbreviated as: COVID-19 is an infectious disease with strong infectivity caused by novel coronavirus, at present, China brings the disease into class B infectious disease, and takes prevention and control measures of class A infectious disease, and the infected people of the infectious disease have susceptibility in different age groups. After respiratory infectious diseases such as COVID-19, patients often have respiratory diseases such as dry cough and dyspnea. According to the diagnosis and treatment opinions from the first edition to the seventh edition of the diagnosis and treatment scheme for the novel coronavirus pneumonia issued by the State Weijian Commission, no specific medicine exists at present in the aspect of resisting the new coronavirus, and trial recommendation is made for the atomization inhalation treatment of the alpha-interferon in the scheme. The method is also the most effective treatment scheme in China aiming at the new coronavirus treatment at present.

However, in practice, this treatment requires the use of an aerosolization device. Due to the limitation of the using principle of the atomization device, the atomization system generally has the condition of gas exchange with the external environment. This results in aerosols carrying large amounts of virus being carried along with the patient's exhaled air into the surrounding ambient atmosphere. This situation increases the risk of infection for medical personnel and other patients. Thus limiting the use of nebulization therapy in COVID-19 therapy.

According to 2020 edition of guidelines for asthma management and prevention strategy (GINA2020) (GINA was created in 1993 by the World Health Organization (WHO) in conjunction with the american society for cardiopulmonary blood research and has been working on the global development of strategies for asthma for more than 20 years.1995 GINA was first published in conjunction with clinical guidelines developed by global asthma experts.since 2002, GINA was updated every year to become the "gold standard" for asthma prevention based on recent evidence from evidence of evidence-based medicine): "avoid the use of nebulizers as much as possible, which increases the risk of viral transmission to medical personnel and other patients. In the acute asthma attack of adults and children, the patient should inhale with a hand-press type metered dose inhaler or a mist storage can, and if necessary, should be equipped with a mouthpiece or a close-fitting face mask. "it can be seen that although nebulization is an effective treatment for COVID-19 disease, it is limited in use due to its adverse effects on health care workers!

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an aerosol pollution prevention atomization device aiming at the problem that the polluted aerosol carrying pathogenic bacteria and viruses exhaled by the patient in the atomization treatment process easily diffuses into the surrounding respiratory environment and causes the risk of infection to medical workers and other common patients.

In order to achieve the above purpose, the utility model adopts the following technical scheme: an aerosol pollution prevention atomization device comprises a mask belt, a mask, a one-way valve plate, an atomization connecting pipe, an atomizer, a water absorption pad and a filter box; two ends of the mask belt are connected with two sides of the mask, and the tightness can be adjusted; the sprayer is connected with an upper connector of the face mask through an atomization connecting pipe, and the one-way valve plate is arranged in the upper connector of the face mask; the filter box is connected with a quick interface below the mask; the water absorption pad is stuck to the bottom in the mask; the air supply conduit of the sprayer is connected with an air source.

Compared with the prior art, the utility model can carry the aerosol which is exhaled by the patient with COVID-19 and carries pathogenic bacteria and virus through installationThe filter element on the sealing mask is discharged into the ambient air after being filtered, so that the effective atomization treatment of the patient is not influenced, the polluted aerosol exhaled by the patient can be ensured not to be diffused into the surrounding atmospheric environment, the medical care personnel and other common patients are protected, and the risk of infection diseases of the medical care personnel and other common patients is reduced. In addition, due to the additional arrangement of the one-way valve plate mechanism, the exhaled gas can be ensured not to flow back into the atomization device and further diffused into the surrounding environment to pollute the environment gas. And can reduce CO in the gas path of the atomization device₂The content of (a), the effect of the atomization treatment is improved.
