続する。2. Description of the Related Art Conventionally, for example, a device disclosed in Japanese Utility Model Laid-Open No. 60-107744 has been proposed as a cleaning device for a medical analyzer for directly applying ultrasonic vibration to a dispensing nozzle to clean the dispensing nozzle. According to the above-mentioned device, as shown in FIG. 5, a certain amount of a sample is sucked and collected through a dispensing nozzle, discharged into a sample tube or a reaction container, and then the dispensing nozzle is washed before dispensing the next sample. In the dispensing machine described above, a sample pump (not shown) and a tube 92 connected to a washing pump (not shown) are connected to the upper end of the dispensing nozzle 91 via a three-way valve (not shown).

Further, the lower end of the horn 95 connected to the ultrasonic transducer 94 is fixed to the nozzle fixing base 93. An arm 96 connected to a transfer device (not shown) is fixed to the ultrasonic transducer 94. With the above configuration, the dispensing nozzle 91 and the ultrasonic transducer 94 can be integrally connected, and the dispensing nozzle 91 and the ultrasonic transducer 94 can be integrally transferred between respective positions. .

である。Further, since the ultrasonic vibrator 94 is connected to the dispensing nozzle 91 via the horn 95 and the nozzle fixing base 93, the ultrasonic vibration energy generated from the ultrasonic vibrator 94 is generated by the horn 95. It is transmitted to the dispensing nozzle 91 via the. The terminals 94a and 94b are formed on the ultrasonic transducer 94 and connected to a drive circuit (not shown),
The ultrasonic vibration energy necessary for the dispensing nozzle 91 is supplied according to the operation of the dispensing machine, the characteristics of the sample to be dispensed, and the like.

注および洗浄が不可能となってしまう問題があった。However, although the dispensing time can be shortened and the analysis accuracy of the sample can be improved in the above conventional technique, a considerable amount of ultrasonic energy, that is, ultrasonic energy, is required to clean the dispensing nozzle in a short time. Large vibration amplitude is required. Generally, an adhesive is often used to join the dispensing nozzle and the tube, and when a large ultrasonic vibration is applied to the dispensing nozzle to obtain a large vibration amplitude, the vibration causes the bonded part to peel off. However, there is a problem that the adhesive strength is reduced by frictional heat and the dispensing nozzle and the tube are disengaged, making dispensing and cleaning impossible.
