Abstract
A disposable blood holding cassette for haemostatic measurements. A single unit is provided having a blood sample container with three separate pressurized blood sample reservoirs. A waste blood collection reservoir is connected to the blood sample container, and connected thereto via first, second and third blood sample tubes. A punching station is provided to accurately punch first and second of the blood sample tubes, simulating haemostasis function in vitro. Measurements may be made of the haemostatic and thrombolytic function of recently sampled blood. The entire device is disposable, isolating any contaminated blood from clinical personnel.
