発明の名称 (英語) DRUG SOLUTION INJECTION DEVICE
発明の概要(英語) Provided is a drug solution injection device that includes: an injection needle (101) made of non-magnetic material, such as, sapphire and sending a drug solution; and an ultrasonic transducer (102) applying ultrasonic vibration to the injection needle (101). The drug solution injection device further includes a fixation plate (103) fixed to the ultrasonic transducer (102) and made of non-magnetic metal. The injection needle (101) is fixed to the fixation plate (103). The ultrasonic transducer (102) is fixed on a base (104) made of non-magnetic metal. The ultrasonic transducer (102) comprises a plurality of piezoelectric elements (121) and (122) that are stacked such that polarization directions thereof are opposite to each other.
