Abstract:
Nebulizers are classic pulmonary drug delivery devices that
convert liquid medication into a mist. The mist is easy to inhale,
making it useful for treating infants, children, and others who may
have difficulty using respiratory inhalers properly. At present all
commercially available nebulizers are open loop system. Hence,
giving an excess amount of mist to the patient may lead to barns or
suffocation of the patient, specially the children whom cannot
express about the feeling.
The project aimed to explore the impacts of nebulisation
process on respiratory change and ECG signals by monitoring them,
before and after treatment. Furthermore, A light weight, closed loop
nebulizer system is designed in the project to control nebulisation
rate according to the measured respiratory change ; If the respiratory
is abnormal during treatment, then the amount of mist reduced. If
there still abnormal, the nebulizer will be turned off and alarm system
will be activated.
