Title:
HIGH-POWER ULTRASONIC COUPLING MEDIUM
Document Type and Number:
Japanese Patent JP2000316871
Kind Code:
A
Abstract:

To quickly avoid the interference state between manipulators by arranging a therapeutic transducer in an envelope body filled with a coupling medium including an aqueous solution of a hydrophilic polymer in an ultrasonic scanning device using a coupling jelly between a probe and the skin of a patient.

A high-power ultrasonic coupling medium including an aqueous solution of a hydrophilic polymer is filled in an envelope body, and a therapeutic transducer is arranged in the envelope body to form an ultrasonic scanning device. Polyvinylpyrrolidone is preferably used for the hydrophilic polymer, and the hydrophilic polymer with the molecular weight of 10,000-100,000 is advantageous. The therapeutic transducer is adapted for transferring high-power ultrasonic waves, and an ultrasonic wave generator is connected to the transducer. The ultrasonic wave generator generating the ultrasonic waves with the frequency of 1-5 MHz, preferably 2-3 MHz, from the transducer by its operation is preferably used.
