Abstract

An autoinjector that includes a canister having a liquefied gas, a flow regulator, and an actuator is provided. The flow regulator engages the canister to receive a flow of gas generated by the liquefied gas. The actuator is coupled to the canister and the flow regulator, and includes a passageway for receiving the flow of gas downstream from the flow regulator. The actuator moves relative to thecanister between an engaged position whereby the flow regulator is in fluid communication with the canister for receiving the flow of gas and a storage position whereby the flow regulator is spaced from the canister.

Description

technical field [0001] The present invention generally relates to drug delivery devices. In particular, the present invention relates to autoinjectors for delivering medicaments through needle-based drug delivery devices. Background technique [0002] An autoinjector is a medical device designed to deliver one or more doses of a specific drug by self-administration through an injection needle. Originally, auto-injectors were designed for military use to resist poisoning by nerve agents. The device then entered civilian use, with the first civilian devices proposed in the mid to late 1970's to dispense epinephrine to treat anaphylaxis. Recently, these devices have become more widely used. [0003] By design, auto-injectors are easy to use and are intended for self-administration by patients, or administration by untrained personnel. As such, they are generally self-contained and designed to require only a few basic steps to operate. [0004] Typically, auto-injectors are...
