Abstract: 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.

Abstract: A mechanical separator for separating a fluid sample into first and second phases within a collection container is disclosed. The mechanical separator may have a separator body having a through-hole defined therein, with the through-hole adapted for allowing fluid to pass therethrough. The separator body includes a float, having a first density, and a ballast, having a second density greater than the first density. A portion of the float is connected to a portion of the ballast. Optionally, the float may include a first extended tab adjacent a first opening of the through-hole and a second extended tab adjacent the second opening of the through-hole. In certain configurations, the separator body also includes an extended tab band disposed about an outer surface of the float. The separator body may also include an engagement band circumferentially disposed about at least a portion of the separator body.

Abstract: A blood collection assembly includes a housing and a cannula extending distally from the housing including a patient end, and a cannula shield removably engaged with a portion of the housing. The cannula shield is capable of shielding at least the patient end of the cannula, and includes a safety shield engagement. The assembly includes a pivoting safety shield engaged with a portion of the housing, which is transitionable from a retracted position in which the patient end of the cannula is exposed, to an extended position in which the patient end of the cannula is shielded by at least a portion of the safety shield. The safety shield includes at least one locking tab releasably engageable with the safety shield engagement, wherein the locking tab is fixedly engageable with a portion of the housing in the extended position.

Abstract: A container for storing a biological sample for molecular diagnostic testing and/or histological testing is provided. The container includes a first chamber for receiving a sample holder therein, a second chamber, and a closure for enclosing the container. A breakable membrane, such as a piercable foil, extends within the container and separates the two chambers. When the breakable membrane is broken, fluid can pass between the first and second chambers. The membrane may be broken through an activator on the closure, such as a depressible member or a rotatable carrier, causing the sample holder to break through the membrane.
