Abstract: The exemplary embodiments may provide and approach to shutting off the alarm of a medicament delivery device without harming the internal printed circuit board assembly (PCBA) of the medicament delivery device. As a result, the PCBA of the medicament delivery device may not be damaged and can be harvested for reuse. Some exemplary embodiments may provide a displaceable component that may be displaced to open an electrical circuit that powers an alarm of the medicament delivery device. In other exemplary embodiments, a user may break the electrically conductive element, such as by applying sufficient force with a tool. In still other exemplary embodiments, the alarm may be shut off by mechanical manipulation of the medicament delivery device.

Abstract: A device for delivering fluid to a user may include a reservoir that holds the fluid and a plunger received in the reservoir. As the plunger is driven into the reservoir, the fluid is driven out; similarly, as the reservoir is filled, the plunger is driven out of the reservoir. The plunger may be moved into or out of the reservoir by the action of a lead screw. The lead screw may include multiple starts.

Abstract: Fluid delivery devices with occlusion management are described. For example, a fluid delivery system may include at least one force element, at least one moveable element configured to be moved in a dispensing direction by the at least one force element during a pump cycle to expel a fluid from the fluid delivery system, and an occlusion management system comprising at least one emergency element operably coupled to the at least one moveable element, the occlusion management system comprising logic operative to activate the at least one emergency element responsive to a determination of an occlusion to provide additional force to move the at least one moveable element in the dispensing direction. Other embodiments are described.

Abstract: Spring-based sensor devices are described. For example, a spring-based sensor system may include at least one spring associated with a mechanical element, the at least one spring operative to change from a first state to a second state based on a configuration of the mechanical element, sensing circuitry configured to determine an electrical property of the at least one spring, the electrical property to have a first value when the at least one spring is in the first state and a second value when the at least one spring is in the second state, and a logic device to determine a status of the mechanical element based on the electrical property. Other embodiments are described.

Abstract: Wearable fluid delivery devices and pump systems having a pump status determination assembly to determine a status of at least one component of a fluid pump are described. For example, in one embodiment, a fluid pump system for a wearable fluid delivery device may include a control system, a first pump element associated with a first electrical element, a second pump element associated with a second electrical element, wherein the first pump element is configured to engage the second pump element to form an electrical circuit between the first electrical element and the second electrical element, the control system configured to receive at least one signal from the electrical circuit. Other embodiments are described.

Abstract: Wearable fluid delivery devices and pump systems having a bistable valve for setting a fluid path in one of a fluid fill state or a fluid delivery state are described. For example, in one embodiment, a fluid pump system for a wearable fluid delivery device may include a pump chamber to store a fluid, a fluid path valve operable with the pump chamber, the fluid path valve may include a fixed portion and a movable portion, a shaft configured to move along the fixed portion to engage the movable portion responsive to a force imparted by an actuator, the movable portion comprising an offset to deflect movement of the shaft to cause the movable portion to pivot from one of a first position to a second position to the other of the first position or the second position responsive to being engaged by the shaft. Other embodiments are described.

Abstract: Embodiments of the present disclosure relate to techniques, processes, devices or systems including a floating microneedle assembly decoupled from the device and protected by a pump housing. In one approach, a wearable drug delivery device may include a pump housing including a base attachable to a user, and a microneedle assembly coupled to a cannula. The microneedle assembly may be operable to deliver a liquid drug to the user, wherein the microneedle assembly comprises a carrier positioned proximate an opening of the base, and wherein the carrier comprises a plurality of microneedles operable to extend through the opening of the base to penetrate a skin of the user.

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.

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.
