Abstract

The present invention provides an apparatus for analyzing samples, including a liquid suction device; a measurement device for measuring samples; and a connection member, connected to the liquid suction device and the determination device. The liquid suction device comprises a suction nozzle, disposed inside a liquid container storing liquid used for measurement on a specimen, for sucking the liquid in the liquid container; a first fluid volume sensor for detecting whether a predetermined volume of the liquid remains in the liquid container; a chamber for storing the liquid sucked via the suction nozzle; and a second fluid volume sensor, disposed inside the chamber, for detecting whether a volume of the liquid lower than the predetermined volume detected by the first fluid volume sensor remains. The measurement device comprises a suction member, for sucking the liquid in a liquid container through the suction nozzle and the chamber; and a controller, for controlling the suction motion of the suction member according to the detection result of the first fluid volume sensor and the second fluid volume sensor. The invention also provides a liquid suction device.

Description

Technical field: [0001] The invention relates to a specimen analysis device and a pipette. Background technique: [0002] Specimen analysis devices such as hematology analyzers and immune analyzers have dispensing equipment for dispensing specimens and reagents. In order to prevent reagent contamination, the dispensing equipment must be cleaned after each dispensing operation. Cleaning agents for cleaning and reagents for specimen analysis are stored in the liquid storage tank. [0003] Conventionally, there have been known pipetting devices for sample analysis for aspirating liquid from a liquid storage tank, and supplying the liquid to a sample analyzer through a supply tube (for example, refer to U.S. Patent No. 7,296,590 and Patent Publication No. Hei 8-146011 ). [0004] The pipetting device disclosed in U.S. Patent No. 7,296,590 is for aspirating reagents for sample analysis contained in a container, and supplies the aspirated reagents to a clinical examination devi...
