WIRELESS PATIENT MONITORING SYSTEM AND METHOD WITH DISPOSABLE SENSOR ACTIVATION

摘要

A wireless patient monitoring system includes a host device configured to pair with one or more wireless physiological sensors to receive physiological data therefrom. The host device includes a nearfield communication (NFC) transmitter emitting an electromagnetic field. The system includes at least one wireless physiological sensor having a sensing element that senses physiological parameter information from a patient, a battery, and a field detection circuit configured to detect NFC field and to generate an activation signal thereupon. A sensor controller is configured to operate in a sleep state that maximizes battery power consumption by the wireless physiological sensor and to receive the activation signal from the field detection circuit when the NFC field is detected. After receipt of the activation signal, the sensor controller operates the wireless physiological sensor in an activated mode that enables full power consumption by the wireless physiological sensor.
