Title:
【発明の名称】超音波治療コントローラ
Document Type and Number:
Japanese Patent JP2002506701
Kind Code:
A
Abstract:
A controller (10) for driving an ultrasonic transducer (14) is enclosed an includes a processor (16), responsive to a feedback signal, generating control signals (40) to an output driver (18) which is responsive to the control signals (40), to cause the ultrasonic transducer (14) to generate ultrasound having a power level corresponding to the control signal (40). The controller (10) is preferably attached to a sensing circuit (12) to determine the amount of the ultrasound conductive gel (22) associated with the ultrasonic transducer (14), and for generating the feedback signal therefrom. The controller (10) includes data logging capabilities to record treatment data and prevent unnecessary extended treatment. The control (10) creates an environment for safer ultrasonic self-treatment by patients. The microprocessor (16) used in the controller (10) can be used to warn of a low battery (3) condition or insufficient amount of ultrasound conducting gel (22). It can limit the usage of the transducer (14) to prevent over treatment by comparing use data with acceptable limits and disabling the transducer (14) if the limits have been exceeded. The device is contemplated to be portable for ease of transport by patients.
