Background

The mist storage tank is mainly used for children and patients who are not well matched with inhalation and hand movements, or patients who have obvious pharyngeal laryngeal local side effects after MDI (pressure directed aerosol) is used. When the aerosol is used for medicine suction, the aerosol is matched with the mist storage tank device, the medicine is not directly sprayed into the mouth, but is sucked after passing through the mist storage tank, so that a better effect is easily achieved, and the quantity of the medicine retained in the oropharynx and the adverse reaction possibly caused by using the medicine can be greatly reduced.

When the aerosol storage tank is used, the atomized liquid medicine enters the aerosol storage tank, a patient needs to inhale the atomized liquid medicine into a bronchus through a mask of the aerosol storage tank, and the patient needs to hold a breath for ten seconds after inhaling the atomized liquid medicine, if the patient does not feel uncomfortable for 30 seconds as much as possible, the patient slowly exhales, and when the MDI needs to be used for multiple times, the patient needs to press the medicine for the second time to dose for a preset time at a preset interval from the first time, for example, the interval is at least 1 minute.

However, since there is no timing device directly connected to the mist storage tank during the use, the dosing interval needs to be controlled by observing other timing devices in order to avoid an excessively short dosing interval during the use, which makes the use of the mist storage tank very inconvenient and affects the use experience of the product.
