Abstract: The Huber needle is drawn into a protective cap and sheath arrangement after use for disposal purposes. The cap is tethered to a housing in which the needle is mounted by the sheath. The sheath is made of a film material that has a high tensile strength and a low percent of elongation, such as polyester. The sheath is initially mounted about the needle in a collapsed accordion-like condition between the cap and housing. When the cap is moved along the needle, the sheath is played out over the needle. The cap houses a spring clip to snap over a bore through which the needle is retracted to prevent re-emergence of the needle. The flexible nature of the sheath allows the sheath to pass about the two legs of the Huber needle.

Abstract: The positive flow needleless connector has a cannula slideably mounted within a tubular housing. A sleeve-like septum seals the cannula from an outside environment while also sealing an internal chamber of the cannula from a flow path in a male luer housing. Movement of the cannula from an extended position to a retracted position against the force of a spring exposes a second inlet of the cannula to the flow path of the male luer housing to permit flow therebetween. During disconnect, the inlet from the cannula is sealed prior to the cannula returning the extended position. This allows fluid to move from a reservoir between the cannula and septum to move into the passage of the male luer housing.
