Abstract: Needle inserting devices, as well as fluid flow connections and infusion medium delivery systems and methods that may be used with needle inserting devices are described, for medical or non-medical systems, such as, but not limited to sensors, monitors, or the like. The needle inserting device and method may operate to insert a needle or cannula through a patient-user's skin, for example, to provide a fluid flow path for conveying an infusion medium through a hollow channel in the needle or cannula and into the patient-user and/or to convey a fluid from the patient-user to one or more sensor elements. Embodiments of the present invention may be configured, as described herein, to provide a reliable, cost effective and easy-to-use mechanism for inserting a needle or cannula to a specific depth into a patient-user with minimal traumatic effect. In some embodiments, a mechanical force in a first direction results in a needle insertion at a non-zero angle relative to the first direction.

Abstract: Various embodiments of the present invention are directed to equalizing pressure in a reservoir containing fluidic media, possibly due to imperfect installation of the reservoir or an external influence such as an altitude or a temperature change. In various embodiments, fluidic media may be expelled from the reservoir through a needle and contained in an interior volume of a pierceable member before the needle pierces the pierceable member to establish a flow path to a user. In other embodiments, fluidic media may be expelled through a port of the reservoir into a chamber. In further embodiments, fluidic media may be expelled through a channel in a plunger head and out a passage in the reservoir when the channel and passage are aligned. In other embodiments, fluidic media may be expelled through a valve, and the valve may be pierceable by a needle to establish a flow path to the user.

Abstract: Various embodiments of the present invention are directed to limiting a presence of air bubbles in fluidic media in a reservoir. Air passages may allow air to escape from fluidic media in a reservoir. Membranes may allow for trapping air bubbles in fluidic media before fluidic media enters a reservoir. A membrane may allow air to flow from a first reservoir containing fluidic media to a second reservoir while plunger heads within each of the reservoirs are moved within the reservoirs. An inner reservoir with a membrane may be moveable within an outer reservoir to allow air to move from the outer reservoir to the inner reservoir. An inner reservoir containing pressurized gas may allow fluidic media to be transferred to an outer reservoir.

Abstract: A delivery device includes a durable housing portion and a separable disposable portion that selectively engage and disengage from each other. The disposable housing portion secures to the patient-user and may be disposed of after it has been in use for a prescribed period. Components that normally come into contact with a patient-user or with an infusion medium, including a pump device, are supported by the disposable housing portion for disposal after the prescribed use, while the durable housing portion supports other components such as electronics for controlling delivery of the infusion medium from the reservoir and a drive device and drive linkage.
