A needle assembly is disclosed. The needle assembly includes a housing having a flash chamber, and having a distal end and a proximal end engageable with a specimen collection container. The assembly includes a cannula having a patient end, a non-patient end, and a sidewall extending therebetween defining a cannula interior. The patient end of the cannula projects at least partially from the distal end of the housing, and the cannula interior is in fluid communication with the flash chamber. The assembly further includes a shield restrainably engaged with a portion of the housing and axially transitionable over the patient cannula from a retracted position in which the patient end is exposed, to an extended position in which the patient end is shielded by at least a portion of the shield, wherein at least a portion of the flash chamber is visible in the retracted position.

A needle assembly includes a housing having proximal and distal ends, an IV cannula projecting distally from the housing, and an IV shield having an engagement. The housing has a shield seat and the IV cannula has a distal tip. The IV shield has a pre-use position where the IV shield covers the distal tip of the IV cannula and the engagement is disengaged from the shield seat, and a use position where the engagement is engaged with the shield seat and the IV shield is adapted to move between a non-shielded position, in which the distal tip is exposed, and a shielded position, in which the distal tip is shielded by the IV shield.

A lancing device includes a housing (10, 12) and a lancet holder movably mounted within the housing. The lancet holder has a forward portion defining a socket (30) for partially surrounding and retaining in use the rear portion of a lancet. A lancet release element (40, 42) can be moved forward to cooperate with lugs on the socket to expand it to allow insertion and/or removal of the lancet with minimal insertion or withdrawal force.

A lancing device comprising a housing and a lancet. The lancet comprises a needle and is configured to be movable within the housing from an operational position to a retracted position. The lancing device further comprises a shroud coupled movably to the housing and initially covering the needle, and a biasing member coupled between the lancet and the shroud. The shroud is configured to, when pressed against a sampling site, move rearwards relative to the housing and, at a first point of the rearward movement, allow the needle to contact the sampling site and subsequently, at a second point of the rearward movement, release energy stored in the biasing member to drive the lancet from the operational position to the retracted position. The housing comprises lancet retaining features configured to retain the lancet in the operational position until the shroud reaches the second point of the rearward movement.
