Title:
ULTRASONIC THERAPEUTIC INSTRUMENT
Document Type and Number:
Japanese Patent JP3270161
Kind Code:
B2
Abstract:
PURPOSE: To prevent the counterflow of the sucked substance when the suction operation is controlled in interlocking with the ultrasonic wave oscillation, by suspending the suction by a suction means in delay by a prescribed time from the time of the stop of the ultrasonic wave oscillation by a suction control means, after the stop of the ultrasonic wave oscillation.
CONSTITUTION: A control circuit 18 is arranged in a device body 1, and an oscillation circuit 5, suction pump 9, water feeding pump 15, pinch valve 19 and a foot switch 20 are connected. When an operator turning-OFF-operates the foot switch 20, the drive for an ultrasonic vibrator element 4 is suspended, and the water feeding pump 15 is turning-OFF-operated in interlocking. Further, the pinch valve 19 is closing-operated in delay by a prescribed time from the time point of the stop of the ultrasonic wave oscillation, and at this time, the middle part of a suction tube 8 is crashed, and a suction passage is cut off. Accordingly, at the time point when the ultrasonic oscillation is suspended, the sucked body liquid and perfusion liquid are recovered free from the counterflow into an abdominal part.
