Epinephrine autoinjector
Epinephrine Autoinjector
The Epinephrine Autoinjector (pronounced as ep-uh-nef-rin aw-toh-in-jek-tor), also known as an EpiPen, is a medical device used to deliver a measured dose of epinephrine (also known as adrenaline) to individuals experiencing a severe allergic reaction, known as anaphylaxis.
Etymology
The term "Epinephrine Autoinjector" is derived from the name of the hormone it delivers, epinephrine, and the method of delivery, an autoinjector. Epinephrine is derived from the Greek words "epi" and "nephros" which mean "upon" and "kidney" respectively, referring to the adrenal glands which are located on top of the kidneys and produce this hormone. Autoinjector refers to the device's ability to automatically inject the hormone into the body.
Usage
The Epinephrine Autoinjector is used in emergency situations to treat anaphylaxis. The device is designed to be used by non-medical personnel, such as the patient themselves or a bystander, and is typically administered into the thigh muscle. The autoinjector delivers a single dose of epinephrine, which works to reverse the life-threatening symptoms of anaphylaxis.
