Embodiment Construction

[0019] Such as figure 1 As shown, the present invention includes an energy transmission part, a forward data transmission part and a feedback information transmission part. The energy transmission part generates the energy of the whole system, transmits the energy to the body through coil coupling, filters out high-frequency interference signals in the body, and finally provides DC bias voltage to the stimulator and the active circuit in the body; the forward data transmission part transfers the digital image The information is transmitted from the outside to the body; the feedback information transmission part feeds back and transmits the information in the body to the monitor outside the body for monitoring. The energy transmission part is the only source of energy for the entire system, the forward data transmission part is the only source of stimulation signals from the internal stimulator, the feedback information transmission part generates in vivo information that needs...

Abstract

The invention comprises: an energy transmission unit, a forward data transmission unit and a feedback information transmission unit. The energy transmission unit is used to generate the energy of whole system, and to transmit the energy to human body through a coil so as to provide the DC offset voltage for the stimulator and the active circuit in human body; the forward data transmission unit is used to transmit a part of digital image information from outside of human body to the inside of human body; the feedback information transmission unit is used to transmit intra-body information to the monitor at outside of the human body for supervision. The energy transmission unit provides energy sources for the other two units above.

Description

technical field [0001] The invention relates to a device in the technical field of medical equipment, in particular to a radio frequency communication device in an implanted nerve stimulator. Background technique [0002] The radio frequency communication devices in implantable neurostimulators are mainly used in cochlear implants and artificial visual prostheses. [0003] Neuroprostheses represented by cochlear implants and visual prostheses mainly include: external information collection part and signal processing part, internal nerve stimulator and electrode part, during which energy and digital image signals are transmitted through radio frequency wireless transmission. First, the signal collection part collects sound or image information, transmits the information to the signal processing part, processes it, encodes it into an electrical signal, and transmits it to the implanted parts in the body through wireless transmission to generate electrical pulses to stimulate t...
