1. An injector device comprising:
a housing;
a container positioned in the housing configured to contain a fluid;
a drive assembly positioned in the housing which, upon actuation, is configured to expel the fluid from the container;
a needle for injecting the fluid to a patient;
a needle actuator assembly comprising a movable portion biased by the drive assembly to move the needle between a pre-use position in which the needle is in the housing, a use position in which at least a portion of the needle protrudes from the housing for delivery of the fluid to the patient, and a post-use position after delivery of the fluid is completed in which the needle is within the housing;
a fluid path assembly in the housing 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,
wherein after a dose of the fluid has been delivered to the patient through the needle, the drive assembly moves the movable portion of the needle actuator assembly to contact a portion of the tube, which presses the tube against the tube crimping arrangement to at least partially restrict fluid flow through the tube.
