Abstract
A method and apparatus are provided for measuring hemostasis. The apparatus includes a torque sensing column having a torque sensing element and a drive ring disposed around a body of the column and in registration with the column so as to allow rotation of the drive ring around a longitudinal axis of the column. The apparatus further includes a first guide shaft rigidly secured to the drive ring, the guide shaft extending parallel to the longitudinal axis of the column and a cup holder movably attached to the guide shaft, allowing the cup holder to move parallel to the longitudinal axis of the column. The apparatus also includes a sample cup adapted to engage the cup holder on a outer surface and the torque sensing element of the torque sensing column on an inner surface.
