Abstract: Disclosed herein is a double reservoir configuration for a spatially efficient pumping mechanism comprising an outer reservoir and an inner reservoir, wherein a linear translation of the inner reservoir causes the inner reservoir to move into the outer reservoir and act as a plunger for the outer reservoir to force fluid contained in the outer reservoir through a first fluid port. A static plunger disposed within the inner reservoir causes fluid disposed within the inner reservoir to be forced through a second fluid port. Also disclosed are various drive mechanisms for causing the linear translation of the first reservoir into the second reservoir.

Abstract: Disclosed herein are drug delivery devices and methods for component positioning of a pump, such as a linear shuttle pump. In some approaches, a system may include first and second terminals movable with respect to one another, and a sensor device operable to detect a change in capacitance between the first and second terminals as the first and second terminals move with respect to one another. The sensor device may include a two-stage charger connected with a controller and a voltage source, the two-stage charger having a first capacitor connected with a first switch and a second capacitor connected with a second switch, the controller being operable to close the first switch to connect the first capacitor with the voltage source to charge the first capacitor, and open the first switch and close the second switch to connect the second capacitor with the voltage source to charge the second capacitor.

Abstract: A novel embodiment of a pump system, for example, of the type that would be used in a wearable drug delivery system, comprises, in a preferred embodiment, a reservoir, a plunger, disposed within the reservoir and driven by a scissor mechanism connected to a drive mechanism through a linkage, such that a force imparted by the drive mechanism in causes the scissor mechanism to expand thereby causing the plunger move within the reservoir to force a liquid drug contained within the reservoir through a fluid port to a patient.

Abstract: An improved wearable drug delivery device and method for removal are provided. In some embodiments, a device may include a device body coupled to an adhesive layer, and a removal element coupled to the adhesive layer. The removal element may include an end section proximate a perimeter of the adhesive layer and a central section connected to the end section, wherein a force applied to the end section causes the central section to transition from a first configuration to a second configuration.

Abstract: A system, techniques, and computer-readable media includes examples that provide an indication of an early exercise detection are described. An example of an early exercise detection application executed by a processor may cause the processor to perform functions and be operable to obtain image data including metadata from a camera of a mobile device during, for example, an unlock procedure of a mobile device. The processor may determine whether the obtained image data includes location or timestamp information in metadata or has image data that may be recognized as exercise-related objects. Based on the determinations, the processor may output an indication of early exercise detection to an artificial pancreas application, which is operable to adjust an amount of insulin to be delivered to a user.

Abstract: Disclosed are examples of reservoir and reservoir systems usable with a wearable drug delivery device. An example reservoir may include a flexible component coupled to a shell component. The shell component may include drainage channels to facilitate extraction of the liquid drug from the reservoir. A reservoir system example may include an exoskeleton configured around a flexible reservoir to guide the expansion and collapse of the flexible reservoir. Alternatively, one or more rigid panels may be coupled to corresponding flat surfaces of the flexible reservoir to guide the expansion and collapse of the flexible reservoir. A further reservoir example may include a flexible thin film reservoir having peel-able restraints configured to seal off corresponding sections of the reservoir, sequentially break, enabling the liquid drug to sequentially fill corresponding sections in a controlled and predicable manner. A wearable drug delivery device example suitable for utilizing the described examples is provided.

Abstract: Disclosed are a system, methods and computer-readable medium products that provide bolus dosage calculations by a control algorithm-based drug delivery system that provides automatic delivery of a drug, such as insulin or the like, based on sensor input. Blood glucose measurement values may be received at regular time intervals from a sensor. Using the blood glucose measurements, the control algorithm may perform various calculations and determinations to provide an appropriate bolus dosage. The appropriate bolus dosage may be used to respond to a trend in a trajectory of blood glucose measurements. In addition, a bolus dosage may also be determined by the disclosed device, system, method and/or computer-readable medium product in response to an indication that a user consumed a meal.

Abstract: Disclosed is a valve for use in a pump for a wearable drug delivery device for moving a liquid drug from reservoir into a pump chamber and thereafter from the pump chamber to a patient interface. The valve can comprise two needles, a first needle in fluid communication with the reservoir and a second needle in fluid communication with the patient interface. The first and second needles may be linearly translated to either cover the lumen opening of a needle with a septum or place the lumen opening of the needle in fluid communication with the pump chamber. When the first needle is in fluid communication with the pump chamber, the liquid drug may be transferred from the reservoir to the pump chamber via suction created by a plunger in the pump chamber. When the second needle is in fluid communication with the pump chamber, the liquid drug may be transferred from the pump chamber to the patient interface via a pressure created by the plunger in the pump chamber.

Abstract: Disclosed herein are wearable drug delivery devices and methods for component positioning of a linear shuttle pump. In some approaches, a pump may include a pump chamber operably coupled with a piston, and a detent apparatus, wherein the detent apparatus comprises a detent body, a detent arm, and a detent engagement member. The detent engagement member may be retained in direct physical contact with first or second arrest locations of either the detent body or the detent arm. The pump may further include a piston grip coupled to the piston, the piston grip including a grip component engaged with an exterior of the piston. Movement of the piston grip may cause the piston to move axially relative to the pump chamber to control receipt and delivery of a liquid drug.
