Abstract

A portable healthcare device is connected to a networked healthcare service to form a connected healthcare system that is configurable to address a particular predicted or emergent healthcare condition or provisioned to address a number of emergent healthcare conditions. A portable sensor detects the predicted or emergent healthcare condition. A two-way communication channel provides instructions to the affected person or those in proximity, takes remote control of the portable healthcare device to deliver a therapeutic intervention, or facilitates a rendezvous with dispatched first responders. A buffered quantity of data that is recorded proactively can be transmitted in order to make a more accurate remote diagnosis. The remote, networked healthcare service can maintain additional information about the device or a person assigned to the device to augment the transmission, including healthcare records, contact information, configuration type of the device including therapeutic capabilities, service billing, facility location of an assigned device, etc.
