Systems and methods for monitoring patient health
First Claim
1. A system for monitoring health of a patient, the system comprising:
- a plurality of wireless sensor devices positioned to monitor one or more physiological parameters of the patient and configured to transmit sensor data representative of the one or more physiological parameters;
a gateway device in wireless communication with the plurality of wireless sensor devices, the plurality of wireless sensor devices and the gateway device forming a wireless body area network, wherein the gateway device comprises two or more radio frequency integrated circuits (RFICs) connected in at least a series or a parallel connection; and
a patient monitoring module configured to receive the sensor data from the gateway device for monitoring the one or more physiological parameters of the patient,wherein the gateway device and the plurality of wireless sensor devices are configured to communicate with each other based on time synchronization signals and a multi-channel adaptive protocol characterized by;
a communication frame structure having at least one beacon time slot for transmitting a beacon signal from one of the two or more RFICs, and a plurality of frequency separated data slots for receiving respective sensor data from a plurality of wireless sensor devices,wherein the multi-channel adaptive protocol comprises simultaneous receipt of the sensor data from more than one wireless sensor devices from the plurality of wireless sensor devices in the plurality of frequency separated data slots in a cascading configuration starting from one of two or more RFICs and successively transmitted to other RFICs of the two or more RFICs based on a hierarchy of available data slots.

Abstract
Aspects of the invention relate to a system and a method for monitoring health of a patient by using wireless sensor devices positioned to monitor one or more physiological parameters of the patient, and a gateway device in wireless communication with the wireless sensor devices, the wireless sensor devices and the gateway device forming a wireless body area network. The gateway device includes two or more radio frequency integrated circuits (RFICs) connected in at least a series or a parallel connection and provides multiple frequency channels for receiving sensor data from the wireless sensor devices, where the sensor data is transmitted based on time synchronization signals and an multi-channel adaptive protocol.
