The study focuses on developing a novel dosage counter system for a low-cost sleeve attachment device for enhancing the usability and functionality of any standard pressurised metered dosage inhaler (MDI). The paediatric metered dosage inhaler sleeve attachment’s (pMDI’s) primary function is to allow patients 5 years and older to safely use their inhalers, particularly in emergencies. Currently patients don’t know how many dosages are remaining in the MDIs, cant activate the devices and refuse to use their inhalers because of stigma, The dosage counter was a critical feature as it was discovered that patients are using empty inhalers, which leads to hospitalizations and increased mortality rates. A dosage counter was found to be a critical feature for the sleeve attachment, as all MDIs should have one.
