Development and validation of a medical device software to size autoinjector components

Résumé

Auto-injectors are medical devices used to inject medication into the intramuscular or subcutaneous layer of the body. They can be used for different disease applications such as anaphylaxis, rheumatoid arthritis, episodic migraines, multiple sclerosis, diabetes, and many others. This study focuses on developing a software application to size autoinjector components for different disease applications. The kinematic properties of an autoinjector are analysed and explained using a mathematical model that focuses on the plunger motion during the injection process. The mathematical model is validated by a physical experiment that uses a high-speed camera to capture the motion of the plunger during the injection process. The plunger displacement increases linearly during the injection process while the plunger velocity increases linearly and then reaches a constant velocity for the remainder of the injection process. The software application is developed using the validated mathematical model and optimising the relevant equations to determine the component dimensions of an auto injector.
