Programmable wireless electrode system for medical monitoring
First Claim
1. A wireless, programmable transceiver adapted to attach to a patch electrode for placement on the surface of a patient'"'"'s body, said transceiver transmitting signals acquired from said electrode to a base unit, comprising:
- an amplifier receiving a signal from said electrode and generating an amplified analog signal;
an anti-aliasing filter removing undesirable frequencies;
an analog to digital converter converting said amplified, filtered analog signal into a digital signal;
a computing platform having a memory storing a set of instructions executable by said computing platform and performing signal processing of said digital signal;
a buffer storing said digital signal for transmission to said base unit;
a wireless transceiver module including an antenna for wireless transmission of said digital signal between said wireless programmable transceiver assembly and said base unit; and
a frequency generator responsive to said computing platform for generating a frequency at which said wireless transmission is to occur;
wherein said computing platform is operative to select a frequency for said wireless transmission in response to control commands received from said base unit at said wireless transceiver module.

Abstract
A wireless, programmable system for bio-potential signal acquisition (e.g., electrocardiogram (ECG) data) includes a base unit and a plurality of individual wireless, remotely programmable transceivers that connect to patch electrodes. The base unit manages the transceivers by issuing registration, configuration, data acquisition, and transmission commands using wireless techniques. Bio-potential signals from the wireless transceivers are demultiplexed and supplied via a standard interface to a conventional monitor for display.
