A fluid connector includes an extending section having a spiked end to pierce a container port. The extending section includes at least one air conduit and at least one fluid conduit therethrough. The extending section further includes first and second abutment members. The first abutment member is adapted to abut a first or air side of the container port upon piercing of the container port, and the second abutment member, which is spaced from the first abutment member, is adapted to abut a second or fluid side of the container port. The fluid connector can further include grasping members extending from the extending section to facilitate rotation of the extending section relative to the container port during piercing thereof. The fluid connector can also include a check valve in fluid connection with the at least one air conduit. The check valve may be positioned within the extending section.

An infusion pump device comprises a pumping means having a fluid inlet which is adapted to be connected to a vial for taking fluid out of the vial and a fluid outlet which is adapted to be connected to an infusion catheter, and a controlling means which is adapted to be connected to the vial and to control pressure inside the vial so as to avoid occurrence of underpressure at the fluid inlet.

Systems and method for improving fluid flow during medication delivery procedures, such as infusions or pooling, are provided. A spike is punctured though a seal in a container. A liquid substance is drained from said container through a pathway in the spike. The spike includes a channel which permit sliding movement of a snorkel for elevation above the liquid substance to permit air to enter the container from outside without foaming the liquid substance.

An infusion set employing a spike cap, arranged at which there is an opening configured to prevent passage therethrough of solid or liquid but to allow passage therethrough of gas at interior of the cap, hydrophobic filter being arranged at a location inward from where a tip of spike is inserted at interior of the cap by way of an insertion port, and a lid exterior of the opening for closing the opening; and in which there are hook(s) for anchoring to infusion tubing and a clip equipped with a catch for a flange arranged at the spike. Employing the cap at the infusion set makes it possible to carry out preprocessing including priming and backpriming by a simple operation without leakage of liquid.

A fluid delivery device includes a housing having a bottom surface configured to be coupled to the skin surface. The fluid delivery device includes a cartridge prefilled with a fluid and configured to be inserted into the housing. The cartridge has a septum configured to be generally perpendicular to the bottom surface when the cartridge is inserted in the housing. The fluid delivery device includes a needle assembly that has a needle that includes a fluid coupling end and a delivery end. The fluid coupling end of the needle is fluidly disengaged from the cartridge in an initial position. The delivery end of the needle extends past the plane of the bottom surface and the fluid coupling end of the needle extends through the septum in a deployed position.

A pierce and fill connector cap for a vial sealed by an elastomeric septum includes a vial collar and a needle holder. The vial collar body defines a collar aperture to be positioned in overlying registry with the septum of the vial, and the needle holder includes a needle holder body providing a means for holding an elongate needle in registry with the collar aperture. The needle holder body being moveable with respect to said vial collar between a first position spaced from the vial collar and a second position proximate the vial collar, such that a needle held by the needle holder will puncture through the vial septum.

Disclosed herein is a fluid infusion device of the type that delivers medication fluid to the body of a patient. The device includes or cooperates with a fluid reservoir, and the device has a sealing assembly to receive and form a fluid seal with the fluid reservoir. A retractable sealing element surrounding a hollow fluid delivery needle may be used to seal a port of the fluid reservoir. The port may include a pressure vent that is sealed by the retractable sealing element. In one variation, the reservoir includes a moving valve sleeve that holds a septum. The septum moves to allow the reservoir to vent, and to form a seal with the port when the needle pierces the septum. In another variation, the device includes a needleless sealing assembly. In yet other variations, the device uses a needled fluid reservoir.

A snorkel for improving fluid flow during medication delivery procedures is disclosed along with related delivery systems and methods. The snorkel includes a fluid passageway forming an interior passageway for ambient air. A fluid control device is located at the fluid passageway and is moveable between a closed position and an opened position to control passage of the ambient air at the interior passageway. The fluid passageway is sized and shaped to permit extension of a first end of the fluid passageway through a seal of a container and above a fluid line of a substance within the container while the container is oriented for infusion or pooling, the substance remains undrained, and a second end of the fluid passageway as well as the fluid control device remains outside of, and spaced apart from, the container.
