Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an oral and nasal aerosol dispenser. Background Art

[0002] The pressurized metered-dose inhaler (pMDI) is currently the most widely used inhalation drug delivery device in clinical practice. It has the advantages of being small and portable, quick-acting, easy to use, and capable of administering multiple doses. When using a pMDI, critically ill patients inhale very little each time, and it is difficult for the elderly, children, and patients with low education to master its operation. In view of the shortcomings of pMDI, the Canadian Asthma Society recommends that any patient using a pMDI, regardless of age, should consider using a spacer as an auxiliary tool. The use of a pMDI plus a spacer has low requirements for synergy in inhaling drugs, a wide age range, and reduces the stress response in the airways caused by propellants.

[0003] However, the existing spacer cannot monitor the breathing rate of the aerosol inhaler, especially when aerosol therapy is given to infants and children, it is impossible to know whether the infants and children refuse to inhale the drug mist with added drug solution by holding their breath, and the effect of the aerosol therapy cannot be guaranteed.

[0004] Therefore, there is an urgent need for a controllable oral and nasal aerosol dispenser that can ensure the atomization treatment effect. Utility Model Content
