摘要:
An automatic analyzer adapted to enhance sample/reagent dispensing accuracy, regardless of a difference in sample/reagent dispensing height of a dispensing probe. When the amount of sample in a sample container is small, tip height “h1” of a sample dispensing probe positioned immediately after it has aspirated the sample decreases below tip height “h′” of the sample dispensing probe positioned immediately before it discharges the sample. The sample in this state takes a concave shape at the tip of the sample dispensing probe positioned immediately before it discharges the sample. When the amount of sample in a sample container is large, tip height “h2” of the sample dispensing probe positioned immediately after it has aspirated the sample increases above the tip height “h′” and the sample takes a convex shape at the tip of the sample dispensing probe positioned immediately before it discharges the sample.

Using an LED element as a light source, a photometric unit including the light source, a light receiving element and other components therebetween is reduced in size. A holder 30 detachable from the device as a unit holds a light emission unit 15 formed of an LED and a light receiving element 21, and the holder is placed inside a thermostatic chamber 18 which holds a constant temperature fluid 17. Thus, the photometric unit is reduced in size.

A plunger 66 is moved downwardly in predetermined distance while the tip of the sample probe 15 is immersed in a sample to suck the sample into the probe. A pressure sensor 26 detects the pressure fluctuation during the suction operation, an AD converter converting the signals into digital signals to send the signals for a signal processing unit 76. The signal processing unit 76 extracts feature variables data of a suction waveform to calculate the Statistical distance D from normal group data. The Statistical distance D an a threshold value th are compared with each other, it is judged that there is an abnormality in the suction operation when the Statistical distance D is more than or equal to the threshold value th. When the Statistical distance D is smaller than the threshold value th, an operation is proceeded to a discharge operation.

Dispensing failure occurs when air-sucking or clogging is caused at the time of sucking sample or reagent by using a dispensing probe. An automatic analyzer is equipped with a dispensing mechanism (15) for dispensing the sample into a reaction container (35) from a reagent container (10) and an analysis means (61) for analyzing contents within the reaction container (35), wherein the dispensing mechanism (15) includes a pressure generation mechanism (69) for changing the pressure within a nozzle and a dispensing flow path (24) for coupling between the nozzle and the pressure generation mechanism (69) and containing pressure transmission medium therein; and further includes an oscillator (27) for applying vibration of a particular frequency to the pressure transmission medium within the flow path, a pressure sensor (26) for detecting the pressure within the flow path, and a mechanism (76) for detecting whether or not the sample is sucked normally into the nozzle based on the amplitude or the phase difference of the component of the particular frequency extracted from the output of the pressure sensor (26).
摘要:
An automatic analyzer includes a plurality of reagent disks having reagent containers thereon, a reaction disk having a plurality of reaction cuvettes and a plurality of reagent dispensing probes arranged on each of the reagent disks. Each of the dispensing probes includes a first arm rotatable about a first rotary shaft and a second arm rotatable about a second rotary shaft arranged on the first arm with the arms being rotatable independently of each other. A mechanism analyzes reactions of the reagents and samples in the cuvettes.
摘要:
An automatic analyzer is disclosed that dispenses a sample and a reagent into each of a plurality of reaction vessels to allow them to react with each other, and that measures the liquid formed as a result of the reaction. This automatic analyzer includes a first reagent storage case for storing the reagent to be used for the reaction, a second reagent storage case for storing the reagent for supplemental purpose, and a reagent conveying unit for conveying the reagent from the second reagent storage case to the first reagent storage case.

A portable wordprocessor has a main body and a display support assembly hinged to the main body. The main body has an information entry keyboard, a function keyboard, a control circuit board and a floppy disk drive. The information entry keyboard and the function keyboard have key tops the heights of which do not exceed the height of the portion of the main body which accommodates the floppy disk drive. The information entry keyboard is disposed along the front edge of the main body, while the function keyboard is disposed between the information entry keyboard and the rear edge of the main body. The floppy disk drive is disposed in lateral alignment with the function keyboard. The display support assembly supports a liquid crystal display device which includes a liquid crystal display portion and a liquid crystal control circuit board which is disposed around the liquid crystal display portion and has a thickness which does not exceed the thickness of the liquid crystal display portion.

This invention relates to an apparatus for analyzing cells in a biological liquid sample, such as blood, in which apparatus a flow passage in a sample pretreatment system can be shortened with a simple construction. A sample metering chamber, a mixing chamber and a measurement liquid extracting chamber are formed in a rotary sliding member of a pretreatment portion. The rotary sliding member is intermittently rotated so as to shift a sample from one chamber to another to perform a necessary treatment. Fluorescence or scattering light with respect to the sample, mixed with a reagent in the pretreatment portion, is detected by a flow cell.
