Ultrasonic irradiation apparatus

Abstract

An ultrasonic irradiation apparatus is presented which is capable of easily irradiating, with ultrasonic waves, a wide area (range) of an object having three-dimensionally curved surfaces. The apparatus includes an ultrasonic irradiator having a plurality of ultrasonic transducers arranged in planar manner, wherein the position of at least a portion of the ultrasonic transducers is arranged to be mutually and flexibly changeable in three dimensions. The ultrasonic irradiator includes a plurality of ultrasonic transducers installed on a surface of a sheet member being flexible and / or elastic or on a net member being flexible and / or elastic. The ultrasonic irradiator further includes a plurality of ultrasonic transducers composed of a flexible piezoelectric sheet member, wherein driving electrodes are arranged on one surface and opposed electrodes are arranged on another surface facing each other. The ultrasonic irradiator may be installed on a surface of a flexible planar bag containing a fluidic material serving as an ultrasonic conductive medium or arranged inside of the planar bag. The apparatus also includes means for moving or tilting the ultrasonic irradiator with respect to an object. The ultrasonic irradiator further has a band holding member for fitting the irradiator to an object.

Description

technical field [0001] The present invention relates to an ultrasonic radiation device, which relates to a device for radiating ultrasonic waves to a body to be radiated over a large area. Background technique [0002] The inventors of the present invention have previously discovered a method of decomposing fat in a living body by radiating ultrasonic waves of a specific frequency to the living body. The present inventor filed a patent application for an ultrasonic irradiation device for fat decomposition (refer to International Laid-Open Publication WO99 / 39677). [0003] In these applications, although it is necessary to radiate ultrasonic waves to the living body, it is difficult to uniformly radiate ultrasonic waves because the living body has a large-area three-dimensional curved surface composed of complex unevenness such as the abdomen, thighs, buttocks, and jaws. radiation on the surface. [0004] In the above-mentioned International Publication Gazette, devices suc...

Therefore, it is more difficult to adjust the weight of the supporting water while the weight of the water is added to the organism

Furthermore, in the device for ultrasonic radiation through the bag-shaped body storing the ultrasonic transmission medium, since the ultrasonic output window of the bag-shaped body is greatly deformed due to gravity when the radiation direction is not approximately vertical, it is difficult to carry out smooth operation. scanning, so radiation poses are limited
