Focusing ultrasonic energy converter for weight loosing

Abstract

The invention relates to a focusing ultrasonic energy converter for weight loosing. A self-focusing ceramic sheet of the ultrasonic energy converter presents the shape of a spherical ring with a hole in the middle, an outer ring is fixed by epoxy resin in an embedding manner through mould pressing, and an inner ring is fixed by a hollow copper stud and an epoxy resin nut in a screwing manner. A shunting tee joint, a hollow stud and a shunting pipe form a specific circulating water system. The piezoelectric ceramic sheet, an electrode slice and a rear cover are compacted and fixed by the nut and the hollow stud so as to form a crimping power supply mode. Compared with a planar ceramic energy converter using an acoustic lens, the focusing ultrasonic energy converter that adopts the self-focusing method of the ring-shaped spherical surface has the characteristics of small focusing field and high energy. The application of the installing method of the hollow stud ensures the degassing water circulation when the energy converter is in working. Moreover, the structure of the energy converter is simple, and the installing and using are convenient.

Description

technical field [0001] The invention relates to an ultrasonic transducer, in particular to a focused ultrasonic transducer for weight loss. Background technique [0002] The technology of using ultrasound to lose weight has been paid attention to in recent years. The principle is to use ultrasonic transmitters to transmit ultrasonic vibration energy to the fat layer through the human epidermis outside the fat layer of the human body. burn off". [0003] This method can effectively reduce the pain of the patient, however, during the transmission of the ultrasonic wave, the human tissues passed by its transmission channel are also subject to the high-frequency vibration of the ultrasonic wave and may be damaged. Many companies and research groups have tried to use focused ultrasound technology to focus the energy emitted by the ultrasonic transducer outside the human body into the adipose tissue to be removed, so that the adipose tissue absorbs a large amount of energy.

Problems solved by technology

Because weight loss and shaping require the transducer to work for a long time, due to the existence of ultrasonic cavitation effect, even if degassed water is used, a small amount of air bubbles will inevitably be generated. After a certain period of time, the air bubbles will accumulate and form as Figure 4 The model shown will seriously affect the emission of ultrasound, and even cause damage to the transducer

At present, companies that use focused ultrasonic transducers for weight loss and shaping are more important, such as Israel’s Ultrashape company, as described in its patent US6,607,498B2, and have not proposed an effective solution to the heat dissipation problem
