A sample testing cartridge is usable to perform a variety of tests on a visco-elastic sample, such hemostasis testing on a whole blood or blood component sample. The cartridge includes a sample processing portion that is in fluid communication with a sample retention structure. A suspension, such as a beam, arm, cantilever or similar structure supports or suspends the sample retention portion relative to the sample processing portion in a unitary structure. In this manner, the sample retention portion may be placed into dynamic excitation responsive to excitation of the cartridge and correspondingly dynamic, resonant excitation of the sample contained within the sample retention portion, while the sample processing portion remains fixed. Observation of the excited sample yields data indicative of hemostasis. The data may correspond to hemostasis parameters such as time to initial clot formation, rate of clot formation, maximum clot strength and degree of clot lysis.

Apparatus and cartridge for hemostasis testing

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.

An improved ear probe tip for the end of a probe which can be inserted into an ear canal. The ear probe tip comprises a body portion having an inner surface, an outer surface, a first end and a second end. The body portion inner surface defines a passage that extends the entire length of the body portion. The ear probe tip also has a plurality of flexible annular flanges disposed at spaced intervals on the outer surface of the body portion.

A novel quick connect electrode headbox is provided with an internal assembly positioned within a housing. The internal assembly has at least one support and a plurality of pivotable electrode receptacle bases pivotably mounted to the at least one support. Further, the plurality of pivotable electrode receptacle bases have a plurality of receptacles each adapted to receive an electrode connector.
