- the dispensing mechanism 105 moves the system water filled in the nozzle, and causes the nozzle 116 to suck and discharge the liquid via the segmental air.
- the dispensing mechanism 105 includes a syringe for moving the system water, and the movement is performed by driving the syringe.
- the dispensing mechanism 105 also includes a drive mechanism such as a motor that causes the nozzle 116 to drive up and down and rotate.
- the sample and the reagent which are liquid samples, are dispensed into the reaction vessel 112, and the sample is analyzed using the change in absorbance of the reaction solution reacted in the reaction vessel 112.
- a specimen such as blood to be analyzed is held in a specimen container 110, and this specimen is dispensed into a reaction container 112 by a nozzle 116.

- FIG. 2 is an enlarged view of the specimen dispensing mechanism.
- the sample dispensing mechanism will be described, but the present invention can also be applied to a reagent dispensing mechanism.
- the specimen is also referred to as a sample.
- a high pressure pump is connected to the flow path of the nozzle 204.
- segmented air 203 is sucked in order to prevent contact between the sample 201 and the nozzle and the system water 202 in the flow path.
- the nozzle 204 rotates and descends on the sample container 205 (sample container 110) to detect the liquid level.
- a dummy sample 207 for eliminating the influence of thinning of the sample is sucked.
- the sample probe rises, rotates on the reaction vessel, descends to the bottom of the reaction vessel, and discharges the sample. At this time, only the measurement sample is discharged without discharging the dummy sample 207 on the reaction vessel.
- the probe is washed by an outer washing operation in which it moves to the washing tank and sprays washing water on the outer wall of the probe, and the inside of the probe is washed by an inner washing operation in which the system water supplied from the water supply tank and pressurized by the high-pressure pump 208 is poured out .
- the system water is poured out by a high-pressure pump as shown at 209.
- the internal washing operation is not performed when the same sample is repeatedly dispensed, but is performed when the next sample is dispensed.
- the electrical physical quantity is a voltage value, a capacitance value, or the like.
- FIG. 3 shows the system water when the dispensing operation is repeated without the internal washing operation under the condition where the segmental air is not normally secured or the abnormal condition such as the situation where the amount of the segmental air is reduced and the contamination is likely to occur.
- FIG. 3 shows data obtained by converting the amount of change in capacitance into a voltage value. Further, the amount of change in capacitance was measured at the upper limit point after the nozzle sucked the liquid and the probe before dispensing was movable. Further, the electrostatic capacity is a value between the nozzle and the GND level, and the converted voltage value is also a value between the nozzle and the GND level.
- the output value of the capacitance detection mechanism 117 a position where the nozzle 116 (204) is not in contact with the sample, for example, the capacitance value C1 at the upper limit point is used.
- the nozzle 116 (204) is made of a conductive material. If the movement of the system water is repeated under an abnormal condition where segmental air is not normally secured during dispensing, contamination between the specimen and the system water is caused. As a result, since the specimen contains ions such as an electrolyte, the system water having low conductivity because of purified water has conductivity. Therefore, by providing a detection mechanism for detecting the conductivity of the system water, it is possible to detect the contamination of the specimen into the system water.
- the capacitance value measured by the capacitance detection mechanism 117 is not contaminated due to the conductivity of the system water. Shift.
- the area that can be regarded as the nozzle side electrode increases when the system water has electrical conductivity and makes electrical contact with the electrode on the nozzle side. Since a circuit is built in which the voltage increases as the capacitance value on the nozzle side increases, the capacitance value increases as the area that can be regarded as an electrode increases due to the conductivity of the system water, and the voltage gradually increases as shown in FIG. Become bigger. Further, as the conductivity of the system water increases, the capacitance value increases, so that the voltage value gradually increases as shown in FIG. Accordingly, by providing a detection mechanism that detects the voltage value or capacitance value, which is an electrical physical quantity, in the nozzle 116 (204), it is possible to detect mixing of the specimen into the system water. Note that when a circuit is constructed in which the voltage decreases as the capacitance value on the nozzle side increases, the change amount of the voltage value changes to the negative side.
- the detection mechanism detects from the relationship between the amount of thinning due to the liquid system water and the amount of change in the electrical physical quantity, the storage unit storing the allowable range of the amount of thinning, and this relationship stored in the storage unit.
- the change amount of the electrical physical quantity can be converted into the thinning amount of the liquid. This conversion can be performed by the control unit 115, and the control unit 115 can determine whether the converted thinning amount is within the stored allowable range. In addition, this determination can be performed similarly with respect to the conductivity and electrical physical quantity of the system water.
- the control unit 115 (1) stops dispensing of the liquid when the nozzle exceeds the allowable value before dispensing the liquid into the reaction container. (2) The inner washing of the dispensing nozzle is performed. The dispensing nozzle holds new system water and dispenses the same liquid again.
- attaching a data flag means attaching a mark to a measurement result in order to distinguish between a measurement result measured within an allowable range and a measurement result measured beyond the allowable range.
- another threshold value may be provided in the range of the allowable value, and the control unit may perform any of the above processes before the threshold value is exceeded and the allowable value is exceeded. In this case, this threshold value can be considered as an allowable value.
- FIG. 4 is an example of a voltage change when the same liquid is repeatedly dispensed while retaining the system water, and internal washing is performed during the dispensing. And as an example of eliminating the thinning by the internal washing and re-dispensing operation, when the thinning equivalent to the voltage 0.2V is the allowable limit, as shown in FIG. 4, it is predicted that the allowable value will be exceeded at the thirteenth time Therefore, the thinning is eliminated by performing the internal washing operation after the twelfth dispensing, and the analysis can be continued within the allowable range. The same can be done for the conductivity and electrical physical quantity of the system water.
- the capacitance value which is an electrical physical quantity
- the conductivity of the system water and the detection of the electrical physical quantity are detected at each dispensing.
- the detection may be performed at the timing when the nozzles are at the same height, and the present invention is not limited to the detection at the upper limit point. In short, the timing does not matter as long as it can be detected under the same height condition. If different samples are used, the detection timing of each sample may be changed. Especially when the same liquid is repeatedly dispensed while the system nozzle holds the system water, it is detected under the same height condition.
- the detection is performed at the timing when the dispensing nozzle is at the same height.
- the upper limit of the vertical drive of the nozzle is farthest from the sample container that causes a change in capacitance etc. at the position farthest from the apparatus, it is electrically relatively stable. Detection is most desirable.
- this electrostatic capacity detection mechanism calculates the electrical conductivity by calculating the electrical conductivity of the system water from the electrical physical quantity. It can also be detected. This is because the degree of conductivity of the system water also changes depending on the degree of change in capacitance.
- a detection mechanism a pair of electrodes may be provided in a pipe filled with system water separately, and the conductivity of the system water may be detected from the voltage value or resistance value between the electrodes.
- some nozzles have a capacitance detection mechanism that detects the liquid level of the specimen by detecting the amount of change in capacitance.
- this capacitance detection The mechanism may be integrated with the detection mechanism, and the detection mechanism may include a capacitance detection mechanism. That is, the same detection mechanism may be used to perform so-called liquid level detection and detection of conductivity and electrical physical quantity according to the present invention. In this case, since it can be a common circuit, there are merits such as omission of parts and the like and miniaturization by sharing.
- an example of an apparatus for determining whether or not the cleaning by the internal cleaning operation is sufficient will be described.
- the detection of the mixing of the sample into the system water when the same sample is repeatedly dispensed has been described.
- the washing degree of the inner washing and the system water used for the inner washing are changed. It is possible to detect an abnormality such as a failure or deterioration of the pump supplying the nozzle, a system water flow path, or the like.
- control unit 115 compares the electrical physical quantity detected by the detection mechanism with the system water in the state where the nozzle is filled with the system water and the reference value after the nozzle is washed, and the degree of washing of the inner wash from the comparison result. Can be determined. This is because if the contamination is not sufficiently eliminated, the sample is mixed in the system water, the conductivity becomes higher than the conductivity of the purified water, and the same phenomenon as in Example 1 occurs.
- FIG. 5 is an example showing the difference in voltage change due to the difference in conductivity of the suction liquid, and shows the relationship between the number of suctions and the voltage change due to the difference in conductivity.
- a blood sample has a low conductivity, and a detergent has a higher conductivity than a sample. For this reason, by allowing the detergent to be dispensed before the internal washing, the system water is easily conductive when compared with the same number of dispensing.
- the dispensing quantity is small by detecting the electrical physical quantity after dispensing highly conductive detergent, such as the timing of nozzle cleaning and the timing of adding a high-agent to the reaction tank
- the abnormality can be detected more accurately. Therefore, it is effective to detect the electrical physical quantity in the state that the nozzle is filled with system water and determine the degree of cleaning before dispensing the sample after the nozzle dispenses detergent. Is the method.
- the conductivity of the detergent is extremely high, the abnormality can be detected not only when the number of aspirations is plural, but also when the specimen is aspirated once.
- the backup process is effective such as performing the cleaning again while monitoring the electrical physical quantity, or stopping the analysis operation or continuing the analysis and assigning a data flag. . That is, any of the methods (1) to (3) in the first embodiment can be adopted.
- the present invention can also be applied to a reagent dispensing mechanism instead of a sample dispensing mechanism. Since other matters are the same as those in the first embodiment, description thereof is omitted.
