For decades, auto-injectors have been widely employed to deliver pre-measured doses of medications, such as epinephrine, subcutaneously or intramuscularly during emergency situations like anaphylactic reactions. However, the high cost and single-use nature have constrained their accessibility for many who need them, prompting a demand for more affordable and eco-friendly alternatives in the form of reusable injection devices and methods.
Purdue University researchers have developed a reusable injection apparatus and method that enables users to self-administer pre-measured doses of medicament compositions subcutaneously or intramuscularly. Designed to be both refillable and resettable, this apparatus facilitates multiple treatments, thereby reducing the overall lifetime cost. It incorporates a spring-loaded injection mechanism that can be recompressed for subsequent uses, as well as a removable cap for easy replacement of the drug vial and needle. This innovative solution caters to the need for a cost-effective and environmentally conscious means of administering medication during emergencies, especially for individuals prone to anaphylactic allergies.
