A blood sampling device has a barrel enclosing a lancet and a spring urging the lancet rearwardly. A dual purpose container fits the rear end of the barrel and its first function is to be pushed forwards relative to the barrel to project the tip of the lancet. A shearable bridge breaks when sufficient pressure is applied, allowing the lancet to retract. The device is then reversed to present the rear end of the container to the drawn blood, which is absorbed thereby. The container with sample for analysis is removed from the barrel which, when the lancet safe inside, can be discarded.

This invention discloses a donor blood sampling apparatus attached to a tubing branch, a donor needle attached to an upstream tube, the donor needle being adapted for drawing blood from a body and a main collection bag attached to a donor tube, characterized by a flow controller. The flow controller includes an inlet flow member including an inlet port connected to the upstream tube and an outlet flow member connected to the inlet flow member and including a first outlet port connected to the tubing branch, and a second outlet port connected to the donor tube, the flow controller having a first position and a second position, wherein in the first position, blood can flow to the sampling apparatus via the first outlet port and the tubing branch, the second outlet port and the donor tube being substantially sealed from blood flowing therein, and wherein in the second position, blood can flow to the main collection bag via the second outlet port and the donor tube, the first outlet port and the tubing branch being substantially sealed from blood flowing therein.

This invention discloses a donor blood donation and sampling system including a donor needle adapted for drawing blood from a body, a blood collection bag coupled to a blood collection conduit which is coupled to the donor needle, a blood sampling conduit also coupled to the donor needle, and a sampling tube assembly arranged for selectable fluid engagement with the blood sampling conduit and for selectable clamping engagement with at least said blood collection conduit. A donor blood donation and sampling method is also disclosed.

A blood collection tube holder assembly is disclosed that includes a needle assembly including a piercing end and a non-piercing end and a generally cylindrical housing including a distal end engageable with the needle assembly, a proximal end adapted to receive a blood collection tube, and a sidewall extending between the proximal and distal ends. A cover is movably associated with the proximal end of the cylindrical body and movable between a closed position covering the proximal end and an open position opening the proximal end.

A sampling apparatus is disclosed that includes a sample container including at least one wall defining a fluid-receiving interior chamber and including a fluid inlet for receiving fluid into the chamber and a sample device receiver carried by the container wall and in fluid communication with the chamber, the receiver being adapted to receive a sampling device for withdrawing a fluid sample from the chamber.
