  • Automatic blood analyzing system
    Patent number: 4218610
    Abstract: A system is provided for the automatic measurement of red and white blood cell counts and other blood parameters. The system includes hydraulic apparatus for the aspiration of a blood sample and the proper measurement of the parameters thereof. During operation, the system directs an operator at each step of the procedure, allowing only permitted functions to be performed, thereby decreasing the opportunity for operator error. Each blood cell count is performed twice and the answers compared, an indication of instrument malfunction being presented to the operator if the measurements do not agree within a predetermined percentage. The system monitors itself to detect malfunctions which may occur and alerts the operator to the occurrence of a malfunction.
    Type: Grant

  • Purging means for aperture of blood cell counter
    Patent number: 4180091
    Abstract: A system for purging the aperture and surrounding portions of a blood cell counter of dirt, debris, and previous sample liquid. A sample tube extends from a source of either sample liquid or cleansing solution to a small gap between the aperture and housing assembly. A purge line is connected between an annular portion surrounding the gap and a pump which supplies negative pressure. Due to the geometry of the sample tube, gap, annulus, and purge line, a high pressure drop occurs across the gap and the liquid flows at relatively high velocity past the aperture to facilitate cleaning.
