Description

Atomization device capable of avoiding cross infection

Technical Field

The utility model belongs to the technical field of the medical instrument technique and specifically relates to an avoid cross infection's atomizing device.

Background

Aerosol inhalation therapy is widely used in medicine, pediatrics, ear-nose-throat department, surgery (perioperative airway management), pregnant and lying-in women and other specialties at home and abroad. Compared with the administration modes of oral administration, intramuscular injection, intravenous drip and the like, the aerosol inhalation therapy has the advantages of quick response, good curative effect, less systemic adverse reaction, no need of deliberate coordination of patients and the like because the medicine directly acts on the target organ.

As a respiratory tract-borne virus that is transmitted mainly by droplets, the new coronavirus mainly invades the human body through the delicate surface of mucous membrane, such as mucous membrane in contact with air in respiratory system such as respiratory tract and lung, and exposed mucous membrane such as the mucous membrane around the eyes, which are infected with the new coronavirus. The aerosol inhalation type vaccine only needs one fifth of the dose of the injection vaccine, and the vaccine is not packed in one bottle, so the bottleneck problem of the vaccine bottle can be solved. The vaccine is atomized into tiny particles by a nebulizer and enters respiratory tract and lung by breathing inhalation, so as to stimulate mucosal immunity, which cannot be brought by intramuscular injection. Immunization using the aerosol inhalation regime is painless and has greater accessibility. Can't once inhale under the normal atomizing medicine use condition and accomplish, have the exhalation process midway, gas, saliva, bacterium, virus can pollute atomizing device in the oral cavity when the exhalation, and even change the mouthpiece or the nose is inserted and still exists the risk of cross infection in the pipeline.

Therefore, there is a need to develop an atomization device that avoids cross-contamination.
