Atomizer

Technical Field

The utility model relates to the technical field of medical instruments, in particular to an atomizer.

Background

Aerosol inhalation therapy is an aerosol inhalation therapy, and a medicine is dispersed into tiny fog drops or particles through an atomizer and other atomizing devices, so that the fog drops or particles are suspended in gas and enter respiratory tracts and lungs through a respiratory inhalation mode, and therefore the purposes of humidifying the respiratory tracts and treating respiratory tract inflammation are achieved. The traditional air compression type atomizer utilizes compressed air to form high-speed air flow through a tiny pipe orifice, and the generated negative pressure drives the liquid medicine in the atomizing cup to be sprayed onto a barrier, so that liquid drops are splashed to the periphery under high-speed impact to become mist particles, and the mist particles are sprayed out from an atomizing nozzle on the atomizing cup. However, when the patient carelessly tilts the atomizing cup beyond 45 degrees in the use process of the traditional atomizer, the liquid medicine which is not atomized in the atomizing cup may directly flow out from the atomizing nozzle along the wall of the atomizing cup as the atomizing nozzle is positioned on the side wall or the top of the atomizing cup, the flowing liquid medicine enters the mouth of the patient, and the patient may inhale by mistake, so that the aspiration pneumonia and even the choking result are caused, and therefore, an improved atomizer is needed to be designed.
