A needle assembly for use with a drug delivery device comprises a cap releasably secured to the drug delivery device and a blocking member. The blocking member comprises a disinfectant swab and a user graspable portion. The blocking member is configured to be physically moved with respect to the needle assembly by a user. The needle assembly is configured such that in an initial position, the blocking member blocks the cap from being removed from the drug delivery device and movement of the blocking member from the initial position causes the disinfectant swab to contact a septum of a cartridge retained within the drug delivery device.

Described is a priming device to prime a gas from a fluid delivery system by receiving the gas and a fluid used to push the gas into a chamber, the priming device including a housing having a chamber, an inlet port, and an opening to release gas received into the chamber. The device further includes a sleeve having an open first end for coupling with a male luer connector, a second end coupled to the housing, and an axis between the first and second ends. The sleeve defines at least one window. The device further includes an arm extending from a bottom of each window toward the first end, and a member extending radially from an inner surface of each arm. Each member has a ramp surface, an engagement surface extending transversely to the ramp surface, and an apex area that transitions between the ramp surface and the engagement surface.

A injection site information cap includes a housing, a cover portion, an engagement portion configured to couple to and cover an injection port of an injection site, and at least one information element on the cover portion that is positioned to be automatically sensed by at least one sensor of the injection site when the engagement portion is coupled to or is being coupled to the medication injection port. Related apparatus, systems, and techniques are also described.

A cap for medical connectors that absorbs deactivates and isolates hazardous fluid residues on the ends of medical connectors after administration of hazardous fluids.

Formation of a sterile connection includes inserting a first aseptic coupling device into a second aseptic coupling device while a locking ring of the first aseptic device is in an indexed initial position, rotating the locking ring to a secured position in which a compressive force is created and in which a first membrane from the first aseptic coupling device and a second membrane from the second aseptic coupling device can removed thereby resulting in a first a first sealing member of the first aseptic coupling device sealing with a second sealing member of the second aseptic coupling device to form a sterile fluid passageway.

A dental instrument water supply filter includes a hollow cylindrical body which bounds an interior area. The interior area houses a plurality of iodinated resin particles. A pair of water permeable discs are positioned in the interior area of the body at opposed axial ends. End caps close the interior area of the body at the respective opposed ends, and each end cap includes a respective removable fluid fitting. Water that is used in connection with the operation of a dental instrument is passed through the filter. The filter provides filtration and reduces microorganisms in the water that is passed therethrough and also releases ions into the water that are effective to reduce the growth of contaminants in the water lines to the instrument.

A coupling member for a closed fluid transfer system includes a housing having a fluid connection and a coupling side. A first channel extends from the fluid connection toward the coupling side for fluidly connecting the fluid connection and the coupling side. An elastomer member surrounds an opening of the first channel, or forms a second channel adjoining the first channel. An elastomer member opening of the second channel is parallel to the longitudinal axis of the housing. The sealing surface is formed between a first position, in which the sealing surface seals the opening or the elastomer member opening of the second channel, and a second position, in which the sealing surface exposes the opening of the first channel or the elastomer member opening of the second channel for fluid communication with the coupling side.

A system for disinfecting a medical device is disclosed that includes an elongate instrument comprising a plurality of optical fibers extending along a length of the instrument to a disinfection zone, and a light source coupled with the instrument configured to propagate light distally along the optical fibers. The elongate instrument can be configured to redirect the light radially outward from the instrument. An elongate instrument for disinfecting a medical device can include a plurality of optical fibers extending along a length of the instrument from a proximal end to a disinfection zone at a distal end, the optical fibers configured to propagate a light along the instrument. One or more reflective surfaces can be located within the disinfection zone, and the reflective surfaces can be configured to direct the light radially outward from the instrument.
