Abstract
A device for collecting a blood sample from a plastic segment tube into a receptacle uses a cylindrical housing containing a hollow needle to puncture the segment tube as it is inserted into the upper port of the device. A series of ribs with tapered medial edges are arranged in a radial pattern around the needle within the upper port to guide and support the segment tube as it is inserted. The ribs are separated by slots that also guide the sealed end of the segment tube. An annular recess around the lower port of the device holds the rim of the receptacle and allows blood released by the punctured segment tube to drain into the receptacle. The annular recess accommodates a wide range of test tube diameters, and exerts only a downward force on the rim of the receptacle when a segment tube is inserted into the upper port of the device.
