Abstract

An autoinjector allows a single use medical device serving for automatic intramuscular injection to deliver a dose of a particular emergency drug through an intuitive activation mechanism. By design and structure, autoinjectors are easy to use and are intended for self-administration by patients or untrained personnel. Depending on the number of drugs filled in the cartridge, autoinjectors are divided by one-chamber type and multi-chamber type. Most autoinjectors may have a special structure including spring-loading syringes and needle which is specially designed to ensure strength due to the necessity of penetration through layers of clothing. The purpose of this study was to introduce the design technology of autoinjector of multi-chamber type that could be released into the two drugs sequentially. Additionally, we verified performance of the prototype developed by applying the design.
