Abstract
There is shown a cartridge assembly which is used to analyze the coagulation of blood when subjected to an additive reagent. A base plate is divided into two sections as a right and left section by means of a longitudinal groove. Located on the right side of the groove is a plurality of first cylindrical chambers. Located on the left side of the groove is a second plurality of cylindrical chambers. The chambers on the right side of the groove have a top depression with sloping sidewalls which are adapted to receive extending tapered flanges associated with the chambers on the left side of the groove. In this manner upon folding or pivoting the cartridge about the groove, the chambers on the left and right side coact with one another. In operation the chambers on the left side of the groove receive a blood sample while the chambers on the right side of the groove receive a suitable reagent. When the apparatus is closed, the chambers communicate one with the other and a support shelf is formed between the chambers. The assembly can be agitated in order to provide a coagulation test.
