Abstract

PURPOSE:To obviate the generation of an error in quantitative determination by sucking surely a prescribed amt. of a sample, and detecting definitely abnormality such as lack of the sample. CONSTITUTION:When a driving device 1 operates and the pore of a metering cock 4 aligns with the pores of stationary cocks 10, 11 where a sample passes, a specified amt. of the sample is drawn into the pore by a sample suction pipe. When the pore aligns to the pore in which diluting liquid passes, the diluting liquid is fed by a diluting liquid pump and the sample in the pore is discharged into a diluted sample tank. When the pore aligns with the pore in which the sample passes, a washing liquid pump operates to supply a washing liquid and to wash the inside of the pipe. The liquid is discharged into a washing vessel. The outputs of air and sample sensors are compared with a reference voltage by the 1st and the 2nd comparators, by which a difference in the output is produced. The output is fed to a discrimination circuit which stops the sample suction pump on confirming that there is no foam and turns the cock 4 thereby diluting the sample.

などの種々の問題があった。Conventionally, when a sample of blood or the like is aspirated, the sample group has hardly been monitored, and judgments have mainly been made from the analysis results.

Furthermore, even if the method has a function of detecting that there is a small amount of sample, there are various problems such as simply emitting a signal that cannot be measured, and thus it cannot be said to be an effective method.

Compare with the reference voltage, 1. ．． produces an output difference of 0. These outputs Q1 and Q2 are sent to the discrimination circuit 23, and after confirming that there are no air bubbles, the sample suction pump 15 is stopped, and the drive device 1 is driven to rotate the metering cock 4 to perform dilution. This is done as follows.

成されている。First, as shown in FIG. It is first emitted when air bubbles are removed in the order of surface liquid → air bubbles → blood, but as shown in FIG. 11, if air bubbles are mixed in again before this initial part reaches the second liquid sensor 20, After waiting for the newest bubble to pass through the second liquid sensor 20, the control signal S is issued. Therefore, there will be some deviation in the suction time, but overall it will be approximately 0.
A sample of 1πl is aspirated, and the sample between the sensors is
Since it is about 15, it does not really matter whether it is the first part or the last part. Also, after the control signal S is issued, new air bubbles are detected at the first liquid sensor 18.
Even if the first liquid sensor 18 and the second liquid sensor 2
There are no bubbles in most of the areas between 0 and problem KI-1.
No. The entire aspiration time is determined by a timer built into the control device 24, and if air bubbles are still mixed in after the time corresponding to the sample aspiration time of approximately 0.1 ml, an alarm is issued as an abnormal condition. is configured so that it is emitted.
