Patent ID: 8131334

Claim:
An intra-body communication (IBC) device being designed and fabricated as a system-on-a-chip (SOC) to monitor a patient's biomedical parameters and comprising: a first electrode having an inner end; and an outer end for connecting detachably to the patient's skin; a second electrode having an inner end; and an outer end for connecting detachably to the patient's skin; an IBC module being connected to the inner end of the first electrode, receiving an external command, transmitting the external command, receiving the patient's biomedical parameters, transmitting the patient's biomedical parameters and comprising a command transmitter being connected to the inner end of the first electrode and transmitting the external command to the second electrode through the first electrode; a data receiver being connected to the inner end of the first electrode and receiving patient biomedical parameters from the second electrode through the first electrode; a wireless communication device being connected to the command transmitter and data receiver, being a wireless transceiver, receiving commands from external sources, sending commands to the command transmitter and receiving, modulating and transmitting patient biomedical parameters to an external recipient; and a biomedical chip being connected to the inner end of the second electrode and a biomedical parameter sensor, receiving activation commands from the IBC module, sampling patient biomedical parameters sensed by the biomedical parameter sensor, amplifying, converting, modulating and transmitting the patient biomedical parameters to the IBC module through the second electrode and the first electrode and comprising a command receiver being connected to the inner end of the second electrode and receiving commands from the IBC module; a micro-control unit (MCU) comprising a data converter control unit and being connected to the command receiver, processing commands from the IBC module, controlling operation of the biomedical chip, being a Universal Asynchronous Receiver Transmitter (UART) that receives an external signal and controlling data transmission; an analog-to-digital converter (ADC) being connected to the MCU, being enabled by a signal from the MCU and for converting analog biomedical patient biomedical parameter signals from the biomedical parameter sensor to digital patient biomedical parameter signals; a data transmitter being connected to and enabled by the MCU, connecting to the inner end of the second electrode, modulating and transmitting digital patient biomedical parameter signals to the data receiver of the IBC module and being an on/off shift keying circuit; and a biomedical parameter amplifier (BPA) being connected to the ADC and a biomedical parameter sensor and amplifying signals received from the biomedical parameter sensor.
