Abstract: Embodiments of the present disclosure relate to techniques, processes, devices or systems for pump devices. In one approach, a wearable drug delivery device, may include a reservoir configured to store a fluid, the reservoir comprising a housing including an outer wall defining an interior chamber, and a drive mechanism for driving the fluid from the reservoir. The drive mechanism may include a plunger received in the interior chamber of the reservoir, a leadscrew extending from the plunger, and a clutch mechanism threadably engaged with the leadscrew, wherein the clutch mechanism is configured to allow the leadscrew to pass through the clutch mechanism when disengaged and is configured to grip the leadscrew when engaged such that the clutch mechanism rotates to advance the leadscrew and the plunger into the reservoir.

Abstract: A novel embodiment of a drive mechanism for use in a pump, for example, of the type that would be used in a wearable drug delivery system, comprises, a cylindrically-shaped slider element configured with a channel on a circumferential surface thereof defining one or more zig-zag-shaped tracks therethrough. One or more pegs are engaged within the tracks, such that a back and forth longitudinal motion of the slider element along a radial axis of the cylinder causes movement of the pegs along one of the tracks through the channel, thus providing a movement of the pegs around the circumference of the cylinder which imparts a rotational motion to a header element disposed co-axially with the slider. The header element is in turn connected to a gear train, for example, a planetary gear box, which is coupled to the pump via a linkage or other type of mechanism.

Abstract: Disclosed herein are various embodiments of a pump mechanism comprising a rigid structure having an open end and a closed end, a plunger disposed in the open end of the rigid structure, and a flexible, fluid-proof sheet of material attached to an inner wall of the rigid structure and bonded to the head of the plunger such as to form a fluid barrier between the interior of the rigid structure and the plunger. Movement of the plunger toward the closed end of the rigid structure causes a rolling corner to be formed between the head of the plunger and the rigid structure and a fluid contained within the pump chamber to be forced out of the pump chamber via a fluid port defined in the closed end of the rigid structure.

Abstract: Disclosed herein is a double reservoir configuration for a pumping mechanism for a drug delivery device wherein one reservoir is rigidly fixed to a housing of the device and the other reservoir moves linearly translates with respect to the fixed reservoir. To avoid having either the input fluid port or the output fluid port moves as the second reservoir linearly translates, one port is in fluid communication with the fixed reservoir and a second fluid port is in communication with the moving reservoir via a hollow tube supporting a static plunger disposed within the moving reservoir. This arrangement provides for the added benefit of allowing air trapped within either of the reservoirs to be almost completely removed as the pump mechanism is filled with the fluid.

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: 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.
