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 specimen collection assembly including a flow control member for adjustably altering a flow path is disclosed. In one configuration, the flow control member defines a regulation channel in fluid communication with a lumen of a cannula, wherein the flow control member is configured to adjustably alter an effective flow distance between the lumen of the cannula and an interior of an evacuated collection container. In another configuration, the flow control member is positioned to vary an effective cross-sectional area of at least one of an inlet port and an outlet port adapted to be in fluid communication with the lumen and the evacuated collection container.

Abstract: A regulator for modulation of the flow rate of blood out of a patient's blood vessel during blood collection is disclosed. The regulator includes a housing having a housing inlet, a housing outlet, and a wall defining a housing interior. At least a portion of the wall includes a flexible member. A valve is associated with the flexible member and is in communication with the housing interior. The regulator is designed so that upon an application of a differential pressure within the housing interior, the flexible member and/or valve automatically move with respect to either the housing inlet or housing outlet to modulate a flow of blood moving through the housing. A manual over-ride device can be provided to enable a user to over-ride the automatic regulation and manually regulate the flow of blood through the housing.

Abstract: A blood separation device that is adapted to receive a multi-component blood sample is disclosed. After collecting the blood sample, the blood separation device is able to separate a plasma portion from a cellular portion. After separation, the blood separation device is able to transfer the plasma portion of the blood sample to a point-of-care testing device. The blood separation device also provides a closed sampling and transfer system that reduces the exposure of a blood sample and provides fast mixing of a blood sample with a sample stabilizer. The blood separation device is engageable with a blood testing device for closed transfer of a portion of the plasma portion from the blood separation device to the blood testing device. The blood testing device is adapted to receive the plasma portion to analyze the blood sample and obtain test results.

Abstract: A flow regulator for a blood collection assembly includes a housing having an inlet and an outlet, which defines an interior space between the inlet and the outlet. A membrane having a first surface and a second surface is disposed at least partially within the interior space. The membrane has a first position where a flow path between the inlet and the outlet is substantially open, and a second position where the flow path between the inlet and the outlet is at least partially restricted. The membrane is configured to move between the first and second positions in response to a pressure differential acting on the membrane.

Abstract: A shieldable needle device includes a hub with and a needle cannula having a puncture tip extending from a forward end thereof, and a shield member in telescoping association with the hub. At least one of the hub and the shield member are adapted for relative axial movement with respect to the other between a first position in which the puncture tip of the needle cannula is exposed from a forward end of the shield member and a second position in which the puncture tip of the needle cannula is encompassed within the shield member. A drive member extends between the hub and the shield member, biasing the hub and the shield member axially away from each other. A packaging cover may further extend about the needle cannula, applying external pressure between the cooperating portions of the hub and the shield.
