Abstract
A system including a plurality of wireless sensors for monitoring one or more parameters of a subject is provided. The wireless sensors can be attachable to or implantable in the subject and form a network. The sensors can include a sensing component configured to detect a signal corresponding to at least one condition of the subject. The sensors further can include a communication component configured to wirelessly transmit the detected signal to at least another of the plurality of wireless sensors, and wirelessly receive a signal transmitted from at least one of the remaining sensors in the network.
Core Innovation
The invention relates to wireless sensor networks for monitoring one or more hemodynamic parameters of a subject using a plurality of wireless sensors attachable to or implantable in the subject. Two or more sensors that are physically disconnected from each other can be selected to belong to at least one cluster, and signals from the sensors in a cluster are combined into a formatted signal in a desired format for monitoring the hemodynamic parameters.
Each wireless sensor includes a sensing component configured to detect a signal corresponding to at least one hemodynamic condition or hemodynamic property of the subject. Each sensor also includes a communication component configured to wirelessly transmit the formatted signal to at least one of the plurality of wireless sensors and to wirelessly receive a signal transmitted from at least one of the remaining sensors in the network.
The invention also provides monitoring parameters of a subject via electrocardiography using the same style of wireless sensor network and cluster-based signal combining. The sensors are attachable to or implantable in the subject, where disconnected sensors are selected into at least one cluster and their signals are combined into a formatted signal in a desired format, and a desired output format can be obtained using vector analysis.
Claims Coverage
The independent claims provide coverage for a wireless sensor network with cluster selection of physically disconnected sensors, signal combination into a formatted signal, and wireless transmit/receive communication between sensors; across the independent set there are three main inventive structures: hemodynamic-parameter monitoring, an apparatus with a master node communicating with each sensor, and electrocardiography-based monitoring of cardiac conditions.
Cluster selection of physically disconnected wireless sensors
Two or more of the plurality of wireless sensors that are physically disconnected from each other can be selected to belong to at least one cluster.
Combined formatted signal in a desired format
The sensors are arranged so that signals from the sensors can be combined to form a formatted signal in a desired format.
Wireless transmission and reception of the formatted signal across the network
Each sensor comprises a communication component configured to wirelessly transmit the formatted signal to at least one of the plurality of wireless sensors, and to wirelessly receive a signal transmitted from at least one of the remaining sensors in the network.
Hemodynamic-condition sensing and monitoring
A sensing component configured to detect a signal corresponding to at least one hemodynamic condition of the subject or hemodynamic property of the subject for monitoring one or more hemodynamic parameters/properties.
Master node wirelessly communicates with each sensor
A master node configured to communicate wirelessly with each of the plurality of sensors.
Electrocardiography monitoring of cardiac conditions
A system for monitoring parameters of a subject via electrocardiography, comprising a sensing component configured to detect a signal corresponding to at least one cardiac condition of the subject.
Across the independent claims, the coverage centers on clustering physically disconnected wireless sensors so their signals are combined into a formatted signal in a desired format, with each sensor having transmit/receive communication with other sensors. One independent claim adds an apparatus including a master node communicating wirelessly with each sensor, and another independent claim specifies an electrocardiography-based system for cardiac-condition monitoring.
