Abstract: A drug delivery device for delivering a medicament includes a pump first housing, a pump second housing, an inlet fluid path, and an outlet fluid path. The pump first housing is at least partially supporting and/or surrounding a fluid displacement assembly. The pump second housing is at least partially supporting and/or surrounding a drive component for driving the fluid displacement assembly. The inlet fluid path is configured to deliver medicament to the fluid displacement assembly. The outlet fluid path is configured to receive medicament from the fluid displacement assembly. The pump first housing and the pump second housing are removably coupled with each other.

Abstract: A drug delivery system includes a delivery container including a container body adapted to accommodate a drug therein, a supply line, and a flow rate monitor. The delivery container further includes inlet and outlet ports and is constructed from a resilient material that exerts an urging force on the drug to expel the drug from the outlet port. The supply line is operably coupled to the outlet port to deliver the drug to a user. The flow rate monitor is operably coupled to at least one of the delivery container or the supply line and includes a digital controller, a fluid valve operably coupled to the digital controller, and a diaphragm assembly in fluid communication with the fluid valve and operably coupled to the digital controller. The fluid valve, the diaphragm assembly, and the digital controller cooperate to regulate a flow rate of the drug.
