Abstract: A drug delivery device and method of using the same may include a housing having an opening and a drug storage container including a delivery member with an insertion end configured to extend at least partially through the opening. The drug storage container may be coupled with the housing such as to substantially prevent relative movement therebetween. A guard may be positioned adjacent to the opening and operably coupled with the plunger biasing member such that a relative movement between the guard and the housing permits release of a plunger biasing member to urge a plunger in to expel a drug from the drug storage container. A lock component may be configured to resist the relative movement between the guard and the housing until the lock component is released by a user force, whereafter the user force drives the housing and the drug storage container toward an injection site.
