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: An insertion mechanism and methods of assembly and operation of a drug pump may include an insertion mechanism housing; a housing cap; a manifold guide; an insertion biasing member initially held in an energized state; a retraction biasing member connected to a hub connected to a proximal end of a needle; and, optionally, a clip retainer. The retraction biasing member is held initially in an energized state between the hub and manifold guide. A manifold has a manifold body and one or more septa defining a manifold header. The retraction biasing member may be held initially energized between the hub and the clip retainer. The needle is advanced by the insertion biasing member(s) from the initial configuration to an administration configuration, opening a fluid pathway from the manifold header to the target. The pump may include an activation mechanism, a drive mechanism, a fluid pathway connection, and the insertion mechanism.

Abstract: A device made of metal or strong plastic that fits the portion of a post that is below ground having an open upper end, a closed lower end, and surrounding side walls with portions of the walls that go up the side of post above the ground some distance less than the length of the post above the ground (see the accompanying diagrams in Document EZMZ Drawing of Invention—FIG. 1-12). The device is dimensioned such that the open upper end has dimensions for receiving the lower end of the post therein with some slightly more significant margin of adjustment in one of the X Y axis and some less significant margin in the other X Y axis. The device fits posts of various sizes with rectangular, cylindrical and triangular shapes. The portion of the side wall that extends up the sides of the post above the ground has an array of holes for fastening the post to the device with bolts or screws. The bottom of the device has an array of holes for drainage.

Abstract: A delivery device includes first and second housing portions that selectively engage and disengage. A reservoir on one housing portion operatively engages a drive device and/or a needle inserting device on the other housing portion. Upon proper engagement of the housing portions, the reservoir operatively couples to the drive device and/or the needle inserting device. A first magnet on the first housing portion and a second magnet (or a magnetically-attractive material) on the second housing portion are positioned to magnetically interact with each other, upon operative engagement of the housing portions. A third magnet on the second housing portion may be opposed to the first magnet to help align the housing portions for connection. A magnet-responsive device may be on one or both housing portions to detect alignment and/or connection of the housing portions.

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 contains a reservoir and secures to the patient and may be disposed of after it has been in use for a prescribed period. A disposable pump assembly selectively connects to the reservoir. The disposable pump assembly includes a pump rotor, a septum and a needle for conveying infusion media from the reservoir to the patient.

Abstract: A fluid infusion system as described herein includes a number of local “body network” devices, such as an infusion pump, a handheld monitor or controller, a physiological sensor, and a bedside or hospital monitor. The body network devices can be configured to support communication of status data, physiological information, alerts, control signals, and other information between one another. In addition, the body network devices can be configured to support networked communication of status data, physiological information, alerts, control signals, and other information between the body network devices and “external” devices, systems, or communication networks. Such external communication allows the infusion system to be extended beyond the traditional short-range user environment.

Abstract: An improved pump, reservoir and reservoir piston are provided for controlled delivery of fluids. A motor is operably coupled to a drive member, such as a drive screw, which is adapted to advance a plunger slide in response to operation of the motor. The plunger slide is removably coupled to the piston. A method, system, and an article of manufacture for automatically detecting an occlusion in a medication infusion pump is provided. The electrical current to an infusion pump is measured. Based on a series of measurements of one or more variables, the infusion pump detects whether there is an occlusion in the system.

A motor is operably coupled to a drive member, such as a drive screw, which is adapted to advance a plunger slide in response to operation of the motor. The plunger slide is removably coupled to the piston. A method, system, and an article of manufacture for automatically detecting a force sensor failure in a medication infusion pump is provided. The electrical current to an infusion pump is measured. Based on the current measurements, the infusion pump detects when the plunger slide is seated in the reservoir, and detects a problem with the force sensor when the force sensor independently fails to register a value indicating that the plunger slide is seated in the 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 and may be disposed of after it has been in use for a prescribed period. Components that normally come into contact with a patient or with infusion media 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 infusion media from the reservoir and a drive device and drive linkage.

The disposable housing portion secures to the patient and may be disposed of after it has been in use for a prescribed period. The disposable housing portion supports an infusion media reservoir and a needle on a moveable platform. The platform is moveable between a first position in which a needle is disengaged with a patient and a second position in which the needle is engaged with the patient.

Abstract: An infusion media delivery device includes a housing having a base adapted to be secured to a user's skin. An infusion media reservoir is supported by the housing. A moveable hollow needle is selectively engageable with the reservoir to communicate infusion media from the reservoir. The needle is supported for movement relative to the housing base between a first position and a second position. The needle is spaced apart from a user's skin when in the first position and the base is secured to the user's skin, and the needle is arranged to pierce the user's skin when in the second position and the base is secured to the user's skin.

Abstract: A needle structure for communicating media to or from a patient includes a hollow shaft having two ends and a longitudinal dimension between the two ends. A passage is provided along at least a portion of its longitudinal dimension for conveying a flowable media. The shaft has at least one bend along its longitudinal dimension to dampen motion of one end of the needle relative to the other end of the needle.
