Continuous wave type Doppler ultrasonic transducer and method for manufacturing the same

The present invention relates to relates to an ultrasonic transducer and its manufacturing method which can be used in the ultrasonic blood flow measuring device using the Doppler effect, configured to include a one-piece piezoelectric element frame of which supports the piezoelectric element, to facilitate the manufacturing of the ultrasound transducer to on the other hand, improves the precision and the distances between each set between the piezoelectric element and to provide a method of manufacturing a continuous wave Doppler ultrasound transducer, and this ultrasonic transducer is configured to allow for blood flow measurement of the body end. Therefore, the configuration to a Doppler ultrasound transducer for a continuous wave according to the present invention comprises a piezoelectric device frame for supporting the transmission piezoelectric element, the receiving piezoelectric element and the transmission piezoelectric element and a receiving piezoelectric element for detecting ultrasonic waves for generating an ultrasonic and, in particular, the piezoelectric element frame provides the two piezoelectric elements are mounted portion and the seat support supporting portion integrally Doppler ultrasound transducer for by manufacturing is easy, and a high performance continuous wave formed by the parts that are mounted to the inside.
