The present invention provides an ultrasonic washer that radiates ultrasonic waves from a plurality of vibration surfaces, radiates ultrasonic waves at the same phase, effectively generates cavitation around a nozzle through ultrasonic vibration, and has a high washing effect. The ultrasonic washer of the present invention is characterized by having: a washing tank in which is washed a nozzle that suctions a sample or reagent; and an ultrasonic vibrator having a piezoelectric element sandwiched between a front mass and a back mass, wherein a diaphragm between opposing upper and lower plates is formed at a leading end of the front mass installed at a leading end of the ultrasonic vibrator, and the nozzle is ultrasonically washed in a region between the upper plate and the lower plate.

Ultrasonic washer and automatic analysis device

A method of washing an aspiration probe of an in-vitro diagnostic system is disclosed. The aspiration probe comprises an outer surface and an inner surface forming an inner space for receiving a fluid. The method comprises dipping the aspiration probe into a first wash fluid so that the outer surface is immersed at least in part into the first wash fluid, aspirating an amount of the first wash fluid into the inner space of the aspiration probe, propagating an ultrasonic vibration to the outer surface of the aspiration probe via the first wash fluid, and rinsing the outer surface and the inner surface of the aspiration probe with a second wash fluid. Further, an in-vitro diagnostic method and an in-vitro diagnostic system are disclosed.

A needle for forming a cut in a reagent bottle lid is shaped such that an expansion portion which pushes and opens a cut and a piercing portion which forms the cut are integrated with each other. Consequently, only a single operation for moving the needle downwardly will form a cut using the needle and expand the cut using the expansion portion. Further, the smaller diameter of the expansion portion than the diameter of a circumscribed circle of a cross section of the piercing portion but equal to or greater than the diameter of the reagent probe can form cuts uniformly.
