A needle hub for a drug delivery device includes a needle holder and a needle attached to the needle holder, a needle actuation assembly configured to move the needle holder from a retracted position, to an insertion position, and back to the retracted position, and a pressure interlock comprising an inlet configured to be in fluid communication with a fluid source, an outlet in fluid communication with the needle, and a lock member. The lock member having a first position where the lock member prevents actuation of the needle actuation assembly and a second position where the lock member allows actuation of the needle actuation assembly. The lock member is moved from the first position to the second position based on a pressure within the pressure interlock.

Capillary-based pressure threshold sensors are provided for liquids that exploit the properties of hydrophobic, superhydrophobic, oleophobic and amphiphobic porous membranes to detect when fluid passes through the membrane in the event of the pressure across the membrane rising above the breakthrough pressure of a fluid. Example implementations are provided of different configurations for a capillary-based pressure threshold sensor, and of how a capillary-based pressure threshold sensor is used in a medication delivery device or other fluid delivery devices to detect occlusion or other fluid flow condition.
