Abstract: A sample testing cartridge is usable to perform a variety of tests on a viscoelastic 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.

Abstract: A device for blood hemostasis analysis is disclosed. A blood sample is displaced to reach a resonant state. The resonant frequency of the blood sample is determined before, during and after a hemostasis process. The changes in the resonant frequency of the blood sample are indicative of the hemostasis characteristics of the blood sample.
