Medical Devices and Medical Equipment Design Epi Epinephrine Auto-injector by Yale Shaw Epi is an auto-injection epinephrine device that users can carry with confidence, erasing social stigma. It's more accessible and elegant than previous life-saving medical devices. When the user senses an allergic reaction, Epi can be quickly accessed to inject epinephrine into their muscle tissue. Upon injection, Epi triggers its smartphone application to notify 911 emergency services of the user's exact location, allergy susceptibility, and personal information. This helps to expedite and reduce onsite emergency response time, thus saving lives.
