ABSTRACT:
A gas flow cartridge in which to conduct analytical coagulation tests on a sample of fluid such as blood includes a tube-like member and a resilient flexible membrane having a slit formed therethrough to divide the tube-like member into an upper reaction chamber in which the test takes place and into a lower reagent chamber which initially contains reagent to be mixed with the sample of liquid upon which the test is to be conducted. The contents of the reagent chamber are forced through the slit in the resilient flexible membrane due to the flexing of the membrane around the slit when pressure is applied. Once the reagent is in the reaction chamber with the sample of fluid, a flow of gas is forced upward through the slit in the membrane during the analytical test.
