Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic chemical analyzer for automatically measuring the amount of a specific chemical substance contained in a test sample, and in particular, enables continuous loading of a test sample such as a blood sample. Automatic chemical analyzer.

[0002]

2. Description of the Related Art In a biochemical automatic analyzer that automatically measures the amount of a specific chemical substance contained in a test sample such as a blood sample, the number of test items is increased and the required amount of test sample is reduced. However, improvement of inspection speed has become a major issue.

As an automatic chemical analyzer for solving this problem, there is an automatic chemical analyzer using a chain type sampler as a sampling system for dispensing a test sample into a reaction container of a reaction system. This chain type sampler links a transfer container containing a sample container in a chain shape, and sequentially transfers the linked transfer containers to a sampling position by a sample transfer device, so that a sample to be tested is introduced into a reaction system. There is a merit that it can be loaded continuously.

The automatic chemical analyzer employing this chain type sampler removes the transfer container of the sample container, which has been sampled during the measurement, from the chain row,
By adding a new transfer container to the chain line, continuous sampling becomes possible without lowering throughput (measurement processing capacity), and the inspection speed of the sample to be tested can be improved.

[0005]

In the conventional automatic chemical analyzer employing the chain type sampler, the transfer container is sequentially transferred to the sampling position by the sample transfer device, and the transfer container is discharged to the supply side of the chain row. By attaching and detaching on the side, continuous loading is possible, and the inspection speed of the sample to be inspected can be improved without lowering the throughput.
Since the sample container transferred by the sample transfer device is visually counted, it is difficult to confirm how many samples have been sampled unless the transfer amount of the sample container is constantly monitored.

Further, when a predetermined number of sample containers are set in the transfer container and the automatic chemical analyzer starts sampling for a predetermined time, the sample container after sampling is removed and a new sample container can be added. However, if this state is overlooked, the timing of attachment / detachment of the sample container may be impaired. Eventually, all the sampling was not completed, and the sample container connected again in a chain shape had to be set in the sampler each time, and it took time to restart the automatic chemical analysis device, and operator's work The burden is heavy. In the conventional automatic chemical analyzer, efficient continuous loading cannot be performed unless the sampling state is always taken into consideration.

The present invention has been made in consideration of the above-mentioned circumstances, and the continuous loading can be easily performed without the operator constantly monitoring the sampling state, and the inspection speed of the sample to be tested can be improved. It is an object of the present invention to provide an automatic chemical analyzer capable of achieving the above.

Another object of the present invention is to provide an automatic chemical analysis apparatus which does not require constant monitoring of the sampling state near the apparatus, reduces the work load on the operator, and improves the workability and the degree of freedom. It is in.

At this time, the reset switch 34 can be operated to reset the counter to the initial value, and the next sampling is similarly started. The lit display of the reset switch 34 disappears when the reset operation is performed.

When the counter detects the required number of samplings again, the lighting notifying means 34 and the sound notifying means 41 are activated again, and the timing of removing the transfer container 19 containing the sample container is again indicated by a lighting display and a voice. Notify by display. In this notification state, the attachment / detachment operation of the transfer container 19 is repeated.

The audible alarm means 41 is kept on for several seconds until the reset switch 34 is reset, so that even if the alarm sound is accidentally missed, the automatic chemical analyzer will come to see. In this case, it is possible to immediately know that the required number of samplings have been completed by the lighting display.
