、現在では広く使用されてもいる。(Prior Art) In recent years, various medical tests, such as blood and urine tests, have become indispensable factors in medical diagnosis. In this case, in order to efficiently process the measurement work for multiple test items, a sample collected only once from the subject (patient) is allocated to multiple test items and measured continuously.

In this state, place the sample container 1 related to the specific specimen to be tested on the container placement surface P,
When the operation start switch (not shown) of the analyzer is pressed, the pulse drive circuit 4 starts operating, and the sample probe 2, which is waiting at the initial position, is driven by, for example, 10 pulses/#.
It is lowered at a displacement rate of 71. When the liquid level detection sensor 3 at the tip of the probe 2 detects the sample liquid level in the container 1, its operation is terminated and the PRO-2 is stopped at that position.

やす等の対策を取り得ることが可能となる。At this time, the calculator 8 calculates the amount of sample in the container 1 based on the above-mentioned calculation formula calculated from each displacement amount of the sample probe 2, and calculates the amount of sample in the container 1 based on this estimated value and the above-mentioned required sample amount. Compare the size of. If the total amount of sample in the container 1 does not satisfy the required sample amount, that is, if the total amount of sample is small, the computer 8 outputs a shortage signal to the alarm means 9, and displays the liquid amount on the CRT monitor, for example. Show what is missing. Therefore, the operator can know that there is a shortage of liquid before starting the subsequent measurement work, and can take measures such as increasing the amount of sample before starting the measurement work.

択することができることになる。However, as one of the countermeasures, a method is known that uses a pure water dilution measurement mode that allows measurement even with a small amount of sample. This mode uses pure water to dilute the sample two to three times before measuring it, but in order to use this mode, it is necessary to set the automatic chemical analyzer to such a measurement mode in advance. There is. In this sense, the illustrated embodiment is configured so that the mode change operation means 10 can be set to an operable state by the shortage signal from the computer 8, and the pure water dilution measurement mode can be selected. There is. Therefore, when the present invention is implemented in the embodiment shown, the operator is free to increase the amount of sample liquid and perform normal measurement operations, or to freely select.

Therefore, in the embodiment configured as described above, it is possible to automatically set the dilution ratio at the same time as the mode change operating means 10 is activated by the shortage signal from the computer 8.
