Abstract
A disposable cartridge for measuring the physical properties of blood is disclosed. A waste compartment supports a platform having first and second syringe fittings. First and second syringes containing blood samples to be measured are positioned within the fittings. At least one testing station is located on the platform for subjecting blood flowing from one of the syringes to a test station, and the testing station is connected at a second end to the waste compartment. Tests on blood running through each of the blood channels may be conducted by inducing various platelet activation conditions, such as piercing a channel, or putting a platelet activating substance within a test channel. The cartridge interfaces with a test stand which will measure pressure changes within each of the test channels.
