Abstract: Reservoir systems with improved wake up and fill volume detection techniques are provided. An example reservoir system may include a flexible reservoir and electrical components for detecting fill volume of the flexible reservoir without adversely affecting performance of the flexible reservoir when receiving or dispensing a liquid drug.

Abstract: A low-force, non-displacement, micro/miniature valve and/or pump assembly is provided. A tube component having a first side port coupled to an inlet portion and a second side port coupled to an outlet portion can be selectively moved to alternatively couple the side ports to a first or second piston pump chamber. First and second pistons can be actuated after positioning the tube component to either draw in fluid or push out fluid from either the first or second piston pump chambers during each actuation of the pistons. The fluid can be drawn in from a reservoir and can be expelled to a patient for providing a dose of the fluid to the patient.

Abstract: A wearable drug delivery device for monitoring unintended over-delivery and/or under-delivery of a stored liquid drug are provided. An absolute pressure sensor can be positioned within the fluid path of the drug delivery device. The absolute pressor sensor can detect both ambient pressure (e.g., absolute or atmospheric pressure) and relative pressure (gage or pumping pressure). Based on the detected pressures, the effects of external ambient pressure on air with the fluid path can be determined during both intended drug delivery events and unintended drug delivery events. In turn, under-delivery and/or over-delivery of the liquid drug can be determined. Based on the severity of the determined under-delivery or over-delivery of the liquid drug, alarms indicating different urgencies can be provided to the user.
