US Patent 9489487 Bio-information sensor monitoring system and method

A bio-information monitoring system passively monitors a patient with a remote portable bio-information unit that takes various bio-information measurements at selected time intervals as well as at random times without patient intervention. The measurements are converted to digital signals which are transmitted from the bio-information unit to a modem when the bio-information unit is in proximity to the modem. The signals are stored in the modem and uploaded to a central monitoring network. Automatic alerts may be sent from the central monitoring network to a treatment provider. The treatment provider may also access the information through secured dedicated websites via the Internet.
