Abstract: A drug delivery device for delivering a medicament includes a housing, a pump, drive component, an inlet fluid path, an outlet fluid path, an inlet pressure sensor, an outlet pressure sensor, and a controller. The pump is coupled with the housing. The drive component is for driving the pump. The inlet fluid path is configured to deliver medicament to the pump. The outlet fluid path is configured to receive medicament from the pump. The inlet pressure sensor is positioned along the inlet fluid path and configured to measure inlet fluid pressure. The outlet pressure sensor is positioned along the outlet fluid path and configured to measure outlet fluid pressure. The controller is workingly coupled with the inlet pressure sensor, the outlet pressure sensor, and the drive component, wherein the controller is configured to adjust at least one parameter of the drive component based on input information received from the inlet pressure sensor and/or the outlet pressure sensor.

Abstract: A flexible plunger rod, drug delivery mechanism, drug delivery device, and methods are described that utilize the flexible plunger rod perform drug delivery operations. In embodiments, the flexible plunger rod can be stored in a curved configuration to thereby reduce a footprint of the drug delivery mechanism and device.

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.
