Abstract: A blood analyzer system transports blood samples through at least one blood analyzer and an automatic blood smear generator under the control of a preprogrammable controller. Blood samples are stored in containers that identify the blood samples they contain. The containers move through the system mounted in protective racks that permit the reading of the identifications. The results of analysis by one or more blood analyzers in the system determines for each sample individually whether or not to make a blood smear. When a blood smear is to be made, the controller makes the smear thickness of each blood sample consistent with other samples whatever the consistency of the sample to be smeared. If a required sample is not made, a detector sounds an alarm, thereby alerting operators that the system has failed.

Abstract: A sampling valve comprises two fixed elements, and a movable element held between these fixed elements, in which a flow-in passage (Q) is provided at one fixed element so as to communicate with at least one of the metering passages (P1) , . . . . Plural flow-out passages (R1), (R2), . . . are provided at the other or one fixed element so as to communicate with different metering passages individually. Relay passages (S1), . . . are also provided at the one or other fixed element so as to mutually connect the metering passages (P1), (P2), . . . in specified combinations. In such a construction, plural sampling routes are formed in the sampling valve. In the sampling valve for aspirating and pushing liquid specimens such as blood in cylindrical shape and removing it quantitatively, only the portion necessary for measurement may be selected and sampled.

Abstract: An apparatus for analyzing liquid specimen comprising a sampling valve (11) consisting of two fixed elements (10), (14), and a movable element (12) held between these fixed elements, sample aspiration means (C0), diluent liquid dispensing means (Ci), and chamber (Bi) for receiving diluent liquid and sample, which further comprises measuring item setting means (30), control means (28) for selectively operating the dispensing means, and driving means (26) for driving each dispensing means according to its control signal. By composing in this manner, in the apparatus for analyzing liquid specimen for aspirating and pushing liquid specimen such as blood in cylindrical shape by means of a sampling valve, taking out quantitatively, treating as required, and analyzing, only a sample necessary for measurement is selected, and is diluted or otherwise treated.

Abstract: Apparatus for reading an identification code from a blood sample container includes an elastic member (42) which engages the upper side (34) of the sample container. A rotary device rotates the elastic member bidirectionally. An up-and-down moving device moves the elastic member up and down. A rotating/up-and-down moving control device (56) controls the movement of the container. An identification code reader (19) reads the sample code from the container, and a reading controller (57) permits the identification code reader to read from the container as it rotates in either forward or reverse direction. The elastic member abuts the upper part of the sample container and rotates it. If the identification code reader cannot read the identification code when the container rotates in the forward direction, the elastic member rotates the sample container in the reverse direction for the identification code to be read again.

Abstract: A blood analyzer system incorporates a conveyor for handling and transporting sample blood through at least one blood analyzer and an automatic blood smear generator under the control of a programmable controller. Blood samples are stored in sample containers having identifiers for the sample blood that they contain. These sample containers are transported through the system in protective racks that permit the reading of the identifiers. The results of analysis by one or more blood analyzers in the system determines the need for performing or omitting subsequent operations on a particular sample blood. When a smeared blood sample is to be made, the controller assures that the smear thickness is consistent with other samples regardless of the thickness or viscosity of the sample blood. If the system fails to make a required smeared blood sample, a detector sounds an alarm, warning of a system failure.
