The present invention provides a piercing member adapted for use with a flow channel. The piercing member has a penetrating member for piercing a solid closure, and is retained to the flow channel, but still allows fluid to flow through the flow channel while retained to the flow channel.

Needleless vial access device

A filter device or apparatus is provided for the separation of materials, especially biomaterials from a fluid sample, under a force such as centrifugation, positive pressure, vacuum, or gravity. The device comprises two or more in-line tubular elements, one or more of which is a module that houses a filter media. The elements have complementary connection structures (e.g., elastomeric seal, O-ring, threads, Luer fittings, compression fittings, bayonet fittings, snap fittings, and the like) such that they can be assembled or reassembled in a train to form a conduit structure for leak-proof passage of a fluid sample volume. The assembly can be disassembled for collection and processing of retentate and filtrate material resulting from the filtration.

Selective separation filter device

A protective shield for a blood sampling unit that is movably engaged to an adapter having a needle attached. The shield attaches to a tube holder when the needle is covered by the shield. Longitudinal grooves on the adapter guide the shield between a first position, covering the needle, and a second, position, exposing the needle. The shield can be locked in either the first position or the second position. The blood sampling unit is safely disassembled or reassembled when the needle is covered by the shield. In an embodiment of the invention, a tip protector, removably attached to the adapter, extends through the length of the tube holder to prevent needlesticks. The blood sampling unit and the tube holder can be assembled and disassembled when the tip protector is attached to the adapter, covering the needle. The tip protector is removed during a clinical procedure and then replaced after the clinical procedure is finished.

A cannula assembly adapted to pierce a solid or unslit closure is disclosed and includes a blunt cannula and a piercing member held in cooperation with or contained within the flow channel of the cannula. Generally, the piercing member includes a tip capable of piercing an unslit stopper or closure and a means to temporarily retain the piercing member from the cannula and prevent inadvertent disengagement of the piercing member from the blunt cannula.

A pre-slit injection site includes a housing with a flow path therethrough. A first end of the housing carries a pre-slit septum. A second end of the housing carries a coupling component to adapt the site to standard vials. The coupling component, a vial adapter, includes an adapter spike with openings allowing for the drainage of fluid in the vial through the spike and into the injection site. The vial adapter is provided with a skirt housing unit which protects the adapter spike in manufacturing and use. The skirt housing unit also provides features to lockingly engage the adapter with injection site to standard vials, despite dimensional variations in vial closures. Another embodiment of the coupling component is a spike having a barb feature capable of insertion into a standard vial or port and resisting disengagement. A blunt cannula is usable with the injection site combined with the coupling components.
