Abstract: In accordance with at least one aspect of this disclosure, a system includes a first wire configured to electrically connect a valve stop to a voltage source, a second wire configured to connect a valve pin to a negative terminal of the voltage source, such that the valve stop, and a valve flap operatively connected to the valve pin are configured to create a closed valve circuit when the valve flap is in a fully open position with the valve flap contacting the valve stop, and an open valve circuit when the valve flap is not in the fully open position. A meter is operatively connected to measure an electrical characteristic of the valve circuit to determine when the valve flap is in the fully open position based on an open/closed status of the valve circuit.

Abstract: A cartridge for containing and dispensing a medicament, the cartridge including a cartridge body having an interior cavity therein, a stopper movably disposed within the interior cavity, and a septum disposed at an opposite end of the interior cavity from the stopper, for containing the medicament within the interior cavity. The cartridge also includes a connection thread integrally formed as a unitary construction of the cartridge body, the thread being disposed at a first end of the cartridge body for connecting a pen needle directly to the cartridge body to pierce the septum and provide communication between the medicament and a patient end of the pen needle.
