Abstract
A sample retention apparatus for use in a device for measuring hemostasis. The device for measuring hemostasis may include a sample articulation apparatus including a guide shaft coupled for articulating motion to a drive motor, a sample carrier secured to and axially moveable along the guide shaft between a sample ready position, a sample testing position and a sample ejection position. The sample carrier therefore articulates in unison with the articulating motion of the guide shaft. A measuring apparatus may include a sensing column. The sample retention apparatus may include a sample cup defining a volume within which a sample may be disposed. The sample cup may be adapted to be operably positioned within an aperture formed within the sample carrier. The sample testing apparatus may also include a sample pin that is engageable with the sensing column. The sample pin may include a tip portion for extending into the sample cup. The sample pin may also include a flange extending radially outwardly from the tip portion for substantially completely enclosing the sample space during measurement of hemostasis.
