Abstract

<P>PROBLEM TO BE SOLVED: To make an operation start notification and an operation condition for a sample arm mechanism, in particular, having a tendency generating contact with an operator easily judgeable, in order to solve problems that a mechanism system of an operation object has been difficult to be judged in a conventional automatic analyzer even when a display for displaying operation conditions of disks exists in the vicinity of the reagent disk and the sample disk, and that the intuitive judgement has been difficult in the operator poor in operation experience of an analyzer, in particular. <P>SOLUTION: A light emitting diode or a light emitting display such as a lamp is set in a sample are 14 itself, an operation time of a driving system is controlled by a CPU or the like, and the purpose of this invention is achieved by displaying an operation will before starting the operation of the sample arm mechanism. <P>COPYRIGHT: (C)2003,JPO

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a relatively short operating time of the sample arm mechanism in a certain cycle,
In an automatic analyzer in which it is difficult to determine the timing to start the operation, an automatic analysis capable of notifying the operator of the operation start warning of the sample arm mechanism system in which the operator is particularly likely to come into contact, the operating status, and the stopped status by the display. It relates to the device.

[0002]

2. Description of the Related Art Japanese Patent Application Publication No. JP-A-6-2139
When the mechanical system is driven as described in Japanese Patent Publication No.
A warning of the start of operation of the mechanical system by a display such as D and voice,
There is a technique for informing the operator of the operation in progress and the end of the operation.

[0003]

However, the conventional technique has a problem in that it is difficult for the operator to judge the mechanical system which is the object of the display, and the operator who has little experience in operating the device cannot judge intuitively. It is an object of the present invention to allow an operator to easily judge whether the sample arm mechanism has started operating and whether it is operating or stopped.

[0004]

The above object is to install an indicator such as an LED or a lamp on the sample arm itself,
This is achieved by controlling the operation time of the drive system by a computer or the like and displaying the operation intention before the operation of the sample arm mechanism is started.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to FIGS. FIG. 1 is a schematic diagram of an automatic biochemical analyzer for carrying out the present invention.

In the biochemical automatic analyzer as shown in FIG. 1, the operator sets the sample container 2 into which the sample has been dispensed on the sample table 1, confirms the presence or absence of the reaction container 7 on the reaction table 6, and looks at the CRT 24. The analysis conditions and parameters necessary for the measurement are input from the keyboard 25 to start the measurement.

By the measurement start command of the keyboard 25, C
The PU 23 outputs an operation command to the sample arm 11 for a sample via the driver 21. The sample arm 11 for sample which has received the operation command moves to the sample suction position 3 and then descends to suck the sample set on the sample table 1.
When the inhalation operation ends, the sample arm 11 for the sample
Moves up to the sample discharge position 8 of the reaction table 6 in which the reaction container 7 is set. Then, the sample arm 11 for samples descends, and the inhaled sample is transferred to the reaction container 7. The sample arm 11 for the sample that has finished discharging the sample moves up and moves to the position of the cleaning layer 13 to clean the inside and outside of the nozzle.

After a certain period of time, the sample table 1, the reagent table 4, and the reaction table 6 rotate, and another sample from the next sample container 2 is sucked by the sample sample arm 11 and transferred to the reaction container 7.

When a certain period of time has elapsed after the sample was dispensed, the reagent sample arm 12 sucks the reagent from the reagent container 5 and reaches the reagent discharge position 9 to the reagent sample arm 12
Rotates to discharge the reagent into the reaction container 7 already containing the sample. After the reagent is discharged, the measurement is started at the measurement position 10, the CPU 23 constantly fetches the data, performs the calculation, and stores the result in the memory 22. At the same time, the data is output to the CRT 24 and the printer 26. These series of operations are performed by the CPU 23 by software programmed based on the time chart as shown in FIG.
Does the control exactly.

In such an apparatus, the CPU is operated from a certain time before the sample arm mechanism for the sample and the reagent is operated.
23 blinks the display LED 15 installed on the sample and reagent sample arm 14 itself as shown in FIG. 2, and the display LED 15 is activated at the timing when the sample arm mechanism operates.
Control is changed from blinking 15 to lighting. Then, the control is changed from lighting to extinguishing the display LED 15 at the timing when the sample arm mechanism stops.

Alternatively, in the above apparatus, a plurality of LEDs having different luminescent colors installed on the sample and reagent sample arm 14 itself as shown in FIG. 3 are used to turn on the stop display LED 16 when the sample arm mechanism is stopped. In advance, the CPU 23 controls to turn on the operation start warning LED 17 and turn off the stop display LED 16 from a certain time before the operation. Then, at the timing when the sample arm mechanism operates, the CPU 23 changes the control so that the operation display LED 18 is turned on and the operation start warning LED 17 is turned off. Further, when the sample arm mechanism stops, the CPU 23 turns on the stop display LED 16 and changes the control from turning on the operation display LED 18 to turning it off.

[0012]

According to the present invention, the CPU controls the display LEDs while constantly controlling the time and controlling the drive of the sample arm mechanism, so that the operator can easily determine the operating condition of the sample arm based on this information. Can be judged. This reduces the possibility of operator injury and process interruption due to contact between the sample arm and the human body, which can occur during temporary contact work with the device, such as removing falling objects and checking the reagent setting status. To be done.
