Abstract:
1. A blood cell analyzer, comprising; a diluent chamber; a first flow path for transporting a diluent contained in a diluent container to the diluent chamber; a pump for supplying a negative pressure for transporting the diluent from the diluent container to the diluent chamber through the first flow path; an air bubble sensor for detecting an air bubble in the first flow path; a second flow path for communicating the diluent chamber and the pump which supplies the negative pressure to the diluent container through the second flow path, the diluent chamber and the first flow path; a valve for opening and closing the second flow path; and a controller for controlling the valve so that the valve closes the second flow path when the air bubble sensor of the first flow path has kept detecting the air bubble for a time period longer than a first predetermined time period.
