Document Type and Number:
WIPO Patent Application WO/2020/054929
Kind Code:
A1
Abstract:
The present invention relates to an ultrasound stimulator used to increase a drug treatment effect for a treatment of a cancer and the like by emitting ultrasonic waves at the body of a user, the ultrasound stimulator comprising: a housing having an inwardly concave shape; and a plurality of channels which are provided on the inner surface of the housing so as to be spaced apart from each other at a predetermined distance, and which independently emit ultrasonic waves to the outside thereof so as to form a wide ultrasonic sound field, wherein the plurality of channels are arranged on the inner surface of the housing in a zigzag shape. The plurality of channels arranged in a zigzag shape generate a sound field for uniformly stimulating breast tissue according to the concave shape of the housing. In addition, the present invention can prevent the application of a local stimulus through a rotary machine for rotating the housing around a rotary shaft while widening the range of ultrasonic waves to be emitted from the plurality of channels, and prevent a uniform and excessive stimulus through a control unit for adjusting an ultrasonic wave emission order of the plurality of channels in response to the output strength of the ultrasonic waves according to a set sequence.
