This invention relates to a physiological sensor which acquires pre-programmed data from an electrode or an electrode array using Radio Frequency Identification (RFID) technology. The source of the sensor may be authenticated by means of a wireless interface between an RFID transponder affixed to the electrode array, and an RFID interrogator embedded in the patient interface cable. The criteria for use are then verified to ensure that they are met by the electrode array before beginning signal acquisition. If the criteria are not met, a message is provided to the user via the monitor.

This invention relates to a system of communicating with a radio frequency identification (RFID) transponder microchip (IC) for the purpose of accessing pre-programmed data. Such system involves direct electrical contact between the system reading the data from the memory in the transponder IC and the IC itself via two mechanical contact points. This system provides an interface with a transponder IC in order to energize the IC. Once the presence of the transponder IC is detected, the host system can read or write to and process preprogrammed data stored in the IC.

Method for detecting and communicating with RFID memory devices

Systems and methods for assessing a patient's risk of poor outcome in real-time are provided. The real-time risk may be used by a physician to guide decision making during a procedure.

System and method for integrating clinical information to provide real-time alerts for improving patient outcomes

System for detecting and communicating with RFID memory devices

An array of electrodes is constructed to allow the user to easily adjust to the correct size of the patient's head. The array is self-adhesive, pre-gelled and disposable. The array fits easily over the temple and forehead areas where EEG signals can be acquired by specially designed monitors for purposes of monitoring a number of bodily phenomena, including but not limited to, depth of anesthesia, and/or ischemia, and burst suppression. The array is connected to the monitor via a tab connector that is integral to the disposable device. The tab connector is insertible into a reusable connector that is part of a monitoring system.

Electrode array system for measuring electrophysiological signals

Disclosed is a system and method for providing information to the user of a medical monitoring or diagnostic device to aid in the clinical decision making process. The preferred embodiment uses two estimators or predictors of the same physiological quantity, with each of the estimators being designed to detect specific states or artifacts in the estimated parameter and thus operating at a different point on its respective ROC curve; one chosen to provide high sensitivity, the other chosen to provide high specificity. The divergence between the estimators is indicated by the use of a shaded region between their respective time trends. The use of 2 estimators of the same parameters with different performance characteristics allows the system and method of the present invention to derive additional information about the underlying physiologic process over and above that which would be available from a single estimator. The system and method of the present invention can derive information from not only the instantaneous values of the estimators and the difference between them, but also from the time trend of the difference.

System and method for facilitating clinical decision making

A sensor system which includes a biopotential signal monitor, a smart sensor and the accompanying hardware and software interface which authenticates the source and validity of the smart sensor and also verifies that the smart sensor meets various criteria for use.

Smart electrophysiological sensor system with automatic authentication and validation and an interface for a smart electrophysiological sensor system

Disclosed is a physiological electrical signal connector system which one connector connected to an electrode set and another connector connected to a digital signal convertor which leads to a patient monitor. Each type of electrode set has a specific code identified with it and when connected to the digital signal convertor, the connector code is recognized by the digital signal convertor. The connector code is then relayed to the monitor which will self-configure based on the identified code.
