Abstract
A drug delivery system for injecting a medicament is provided. The system includes a container configured to receive a medicament; a drive assembly which, upon actuation, is configured to expel the medicament from the container; a needle for injecting the medicament to a patient; a fluid path assembly comprising a tube in fluid communication with the container and the needle for conducting fluid from the container to the needle; and a tube crimping arrangement configured to engage the tube to block fluid flow through the tube. The drive assembly causes the tube crimping arrangement to engage the tube after a dose of the medicament has been delivered to the patient through the needle.
