Abstract
The present invention relates to an apparatus for treating a pathology, comprising: an ultrasonic generation device (1), a remote control unit (2) to supply electricity to the device (1), electrical connection means (31, 32) between the device (1) and the control unit (2), remarkable in that the control unit (2) is programmed to assess the quality of the acoustic coupling between the ultrasonic device (1) and a tissue to be treated.
Claims19
An apparatus for treating a pathology comprising:
- an ultrasonic device including at least one transducer configured to generate ultrasonic waves, the at least one transducer having a front face facing a target medium,
- a remote control unit configured to determine and monitor operating parameters of the ultrasonic device, and to supply said ultrasonic device with electricity during at least one treatment cycle, wherein each treatment cycle is preceded by a wait cycle, and
- electrical connection means between the ultrasonic device and the control unit,
- wherein the control unit is programmed to implement an estimation phase of the quality of an acoustic coupling between the ultrasonic device and the target medium, said estimation phase comprising:
- the emission, by the control unit, of at least one monitoring signal, each monitoring signal having a respective frequency,
- the measurement, by the control unit, of at least one reflected signal, each reflected signal corresponding to a respective monitoring signal, and
- the processing of the reflected signal to detect:
- either the presence of a liquid in the ultrasonic device,
- or the presence of a reflective material, such as a gas bubble, between the at least one transducer and the target medium.

An apparatus for treating a pathology comprising:
- an ultrasonic device including an electronic card and at least one transducer electrically connected to the electronic card, the at least one transducer being configured to generate ultrasonic waves,
- a remote control unit for determining and monitoring operating parameters of the ultrasonic device, and supplying said ultrasonic device with electricity during at least one treatment cycle, each treatment cycle being preceded by a wait cycle,
- electrical connection means between the ultrasonic device and the control unit, wherein the control unit is programmed to implement a detection phase of an operating fault of each transducer of the ultrasonic device, said detection phase comprising:
- the emission, by the control unit, of at least one test signal, each monitoring signal having a zero frequency,
- the measurement, by the control unit, of at least one reflected test signal,
- the processing of the reflected test signal to detect:
- either a short circuit in the ultrasonic device,
- or an electrical connection fault between said and at least one transducer and the electronic card.
