    • A method and apparatus for communicating with and monitoring the operation of a device implanted within a patient. A transceiver capable of being implanted within a patient provides a communication interface between an implanted medical device and a monitor external to the patient's body. The external monitor can communicate with a remote monitoring center over a communication network. The external monitor also provides control signals to the implanted device via the transceiver unit. The transceiver apparatus is capable of two-way communication between the implanted device and the external monitor. The transceiver apparatus is also capable of detecting actions performed by the implanted device and physiological signals directly from the patient's body. Thus, the transceiver apparatus provides circuitry for determining whether an implanted medical device is operating properly. The transceiver apparatus provides a way to remotely reprogram one or more implanted medical devices.
    • 一种用于与植入在患者体内的装置的操作进行通信和监测的方法和装置。 能够植入患者体内的收发器提供植入的医疗装置与患者体外的监视器之间的通信接口。 外部监视器可以通过通信网络与远程监控中心进行通信。 外部监视器还通过收发器单元向植入装置提供控制信号。 收发器装置能够在植入装置和外部监视器之间进行双向通信。 收发器装置还能够直接从患者身体检测由植入装置和生理信号执行的动作。 因此,收发器装置提供用于确定植入的医疗装置是否正常工作的电路。 收发机设备提供远程重新编程一个或多个植入式医疗设备的方式。

    • An abnormality detection circuit monitors the sink current Irnf of a H-bridge circuit and determines the presence of an abnormal state if the sink current is not detected for a predetermined time. The abnormality detection circuit includes a clock pulse generator, a counter and a NMOS transistor. The abnormality detection circuit includes a clock pulse generator arranged to generate a clock pulse of a predetermined frequency, and a counter arranged so that a count value is incremented every time the clock pulse is provided to the counter and arranged so that the count value is reset when the sink current is detected. The counter generates a first abnormality detection signal that changes from a normal logic level to an abnormal logic level when the count value reaches a predetermined value without being reset.
    • 如果在预定时间内没有检测到吸收电流,则异常检测电路监视H桥电路的吸收电流Irnf并确定是否存在异常状态。 异常检测电路包括时钟脉冲发生器,计数器和NMOS晶体管。 该异常检测电路包括:时钟脉冲发生器,其被配置为产生预定频率的时钟脉冲;以及计数器,其被布置为使得每当将时钟脉冲提供给计数器时计数值增加,并且被布置成使得计数值被重置 当检测到吸收电流时。 当计数值达到预定值而不被复位时,计数器产生从正常逻辑电平变为异常逻辑电平的第一异常检测信号。
