A multi-use drug delivery device for extended use, wherein the multi-use drug delivery device comprising a multi-use main portion (310) and a single-use flow conducting device (360) adapted for conducting drug to the subcutaneous tissue of a subject, wherein the change from a connected configuration to an unconnected configuration of the main portion and the flow conducting device is through the intermediate configuration. The intermediate configuration comprises an equalizing channel defining an equalizing flow path (304) different from an unintended flow path (303). The equalizing channel is adapted for equalizing the fluid pressure in a fluid communication volume (301) to the fluid pressure in the external environment, upon changing the configuration from the connected to the intermediate configuration and thereby expanding an internal volume, whereby an equalizing fluid flow along the equalizing flow path is larger than an unintended flow along the unintended flow path, whereby equalization of the fluid communication volume is provided with a reduced risk of introducing microorganisms from the flow channel (362) into the reservoir (311).

A cover (50) is configured to enclose a pen needle or a safety pen needle (10). The cover (50) comprises a proximal end (52) in communication with an opening (58), the pen needle or the safety pen needle (10) disposed in the opening (58), a first seal (72) disposed at the proximal end (52) of the cover (50) to seal the opening (58), a cavity (56) disposed at a distal end (54) of the cover (50), a swab (60) disposed in the cavity (56), and a second seal (70) disposed at the distal end (54) of the cover (50) to seal the swab (60) in the cavity (56). The swab (60) contains at least one of an alcohol antiseptic, a non-alcohol antiseptic, and a numbing agent.

A delivery device for delivering a gel or liquid pharmaceutical to a treatment site, the delivery device including a body extending from a delivery tip, the body defining a cavity for retaining a pharmaceutical or a pre-assembled cartridge holding the pharmaceutical; and a driver for mechanically discharging the pharmaceutical from the cartridge to the delivery tip. The driver may be adapted to release a consistent flow of the pharmaceutical. In addition, the delivery device may be biased into a release configuration.

Syringe tip caps are described herein. Such syringe tip caps may include a cup, a cap, a locking feature, a peelable seal and an absorbent material. The cap having locking features and a chamber appropriately sized to adapt to and interlock with an annular wall of the cup.

Syringe assemblies are provided including a partially pre-filled syringe barrel and a plunger rod that incorporates one or more retention elements on the plunger rod that prevents solution from entering a non-sterile area of the syringe when the plunger rod is pulled back. Methods to manufacture a sterilized partially-filled pre-fill syringe assembly are also disclosed.

A dual lumen IV administration set includes a first lumen having an inner diameter of a first value. A second lumen is paired with the first lumen, and the second lumen has an inner diameter of a second value that is greater than the first value. A flow merger merges flow output from a distal end of the first lumen and flow output from a distal end of the second lumen to form a single flow output in an exit lumen. An injection port intersects the first lumen, thereby providing injection access to flow therethrough, prior to merging with the flow output of the second lumen.

The invention discloses a sterile syringe (100) comprising a barrel (1) having internal surfaces (2), a plunger (3) movable within the barrel, a non-sliding seal (7) between the barrel and the plunger defining a sealed volume (8) and at least one filter (9) allowing only filtered gases to enter the sealed volume such that the syringe maintains its sterility even after several uses. The filters could be positioned on different locations on the syringe like on the non-sliding seal, the barrel, the barrel flange or the plunger handle.

Medicant mixing/administration systems are provided that can include: a medicant vial; a syringe assembly comprising a barrel and a piston; a protective material supporting the syringe assembly and medicant vial; and a member within the system, the member separating the piston of the syringe assembly from the medicant vial. Systems are provided that can include: a syringe assembly comprising a barrel and a piston; having a forward end and an opposing back end; a protective material supporting the syringe assembly; and a needle housing coupled to the protective material. Medicant mixing/administration methods are also provided that can include, within a package, sufficiently clearing a restraining member from between a medicant vial and syringe plunger to pierce the medicant vial with a piercing structure coupled to the syringe plunger, the piercing providing medicant from the vial to the syringe assembly. Additional methods can include, upon opening a package containing a syringe assembly, extending a needle housing from the package.

A syringe device includes a syringe barrel and piston having a fluid passageway extending from a vial port. Another syringe device includes a syringe barrel, a piston sleeve and an insert. A channel extends along a side of the insert. A valve controls fluid communication between the channel and the syringe barrel. Another syringe device has a syringe barrel, a piston sleeve and an insert. A valve controls fluid communication between a compartment within the insert and the syringe barrel. A method of preparing a medication includes providing a component within a syringe barrel and another component within a compartment of a piston insert. A seal is over-molded onto a tip of the insert and an end of a piston sleeve. The sleeve is rotated relative to the insert to establish fluid communication between the compartment and the barrel chamber.

Syringe assemblies are provided including a partially pre-filled syringe barrel and a plunger rod that incorporates one or more retention elements on the plunger rod that prevents solution from entering a non-sterile area of the syringe when the plunger rod is pulled back. Methods to manufacture a sterilized partially-filled pre-fill syringe assembly are also disclosed.
