Smart inhaler mask for portable medical gas cylinders utilizing IoT technologies

Over the past decade, there has been a significant increase in the development of wearable and smart health devices based on the Internet of Things (IoT), that enable real time remote control and monitoring of health parameters. In this context, the purpose of this article is to present the development and evaluation process of a smart inhaler mask designed for medical gas cylinders, utilizing IoT technologies. Handheld medical gas cylinders, although essential for a specific group of people, often come with a significant cost, and lack features such as dosage measurement and gas storage monitoring. Consequently, a smart inhaler mask was developed to address these limitations by enabling in-situ and real-time measurement of gas dosage, tracking the remaining gas within the cylinder, and assisting users in monitoring the overall usage of the medical gas cylinder. To facilitate the access and interpretation of this information, a newly developed and user-friendly Graphical User Interface (GUI) has been implemented in the form of a mobile application. This study outlines the evaluation process employed to verify the reliability and accuracy of the results obtained from the smart inhaler mask.
