Abstract: Disclosed are examples of a device, a system, methods and computer-readable medium products operable to implement functionality to determine and respond to a purpose of a meal. An algorithm or application may receive data that may include data related to a meal purpose from data sources and determine whether any of the data received from the plurality of data sources was received from a direct data source or an indirect data source. The data may be evaluated to determine a purpose of the meal. Based on the results of the evaluation, instructions may be generated to provide an appropriate response based on the determined purpose of the meal. The generated instructions to provide the appropriate response based on the determined purpose of the meal may be output.

Abstract: A multiple pulse volume shuttle pump powered by a shape memory alloy (SMA) wire is disclosed. In some embodiments, a shuttle pump system may include a pump chamber, a valve operable with the pump chamber, and a wire coupled to a valve shaft of the valve for controlling a position of the valve. The shuttle pump system may further include a pin disposed within an inset pathway of a cam, wherein the pin is moveable between multiple positions of the inset pathway in response to actuation of the valve shaft.

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.

Abstract: Disclosed are a device, system, methods and computer-readable medium products that provide an updated insulin-to-carbohydrate ratio and an updated total daily insulin. The described processes may be used for periodic updating of the insulin-to-carbohydrate ratio and the total daily insulin. The insulin-to-carbohydrate ratio and/or the total may be used in the calculation of new doses of insulin that a drug delivery device may be commanded to deliver to a user.

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: Examples of fluid delivery drive system and/or pump system that creates a vacuum in a fluid line for drawing and expelling fluid are provided. The vacuum may be created by separating two components that are positioned within the sealed fluid line. Once the two components are separated and the fluid is contained within the volume created between the separated components, the two components may be shuttled within the sealed volume. The movement of the two components can seal off an inlet to the fluid line and then open a pathway to an outlet from the fluid line while ensuring the created volume between the two components is maintained constant. The two components can then be moved back together to expel the fluid from the created volume through the outlet for delivery, for example, to a patient. Other examples are disclosed and described.
