Abstract

A monitoring device for monitoring the vital signs of an infant is disclosed herein. The monitoring device is preferably comprises an article, an optical sensor, an accelerometer and processor. The optical sensor preferably comprises a photodetector and a plurality of light emitting diodes. A sensor signal from the optical sensor is processed with a filtered accelerometer output signal from the accelerometer to create a filtered vital sign signal used to generate a real-time vital sign for the infant which is preferably sent to a mobile communication device.

Claims

1. A method for monitoring a plurality of real-time vital signs of an infant with a wireless monitoring device, the method comprising:

generating a digital signal corresponding to the flow of blood through an artery of the user, the digital signal generated from an optical sensor in proximity to the artery of the infant, the optical sensor comprising a photodetector and a plurality of LEDs, the optical sensor positioned on a monitoring device, the monitoring device configured to be attached to infant, the monitoring device comprising a processor, an accelerometer and a short range transceiver, the accelerometer, the short range transceiver and the optical sensor in communication the processor and positioned on a housing;

filtering motion noise from the digital signal utilizing the accelerometer on the monitoring device;

processing the digital signal on the processor of the monitoring device to obtain an average pulse value of a first set of time periods;

processing the digital signal on the processor to obtain an average pulse value of a second set of time periods, the second set of time periods less than the first set of time periods;

subtracting on the processor the average pulse value of the second set of time periods from the average pulse value of the first set of time periods to generate a first filtered pulse data value;

processing on the processor the first filtered pulse data value to obtain a first heart rate value;

using on the processor the first heart rate value to filter the subsequent average pulse values generated from the digital signal to obtain a real-time heart rate value of the user;

transmitting the real-time heart rate data of the user from a short range transceiver of the monitoring device to a base station, the base station comprising a short range transceiver;

transmitting the real-time heart rate of the infant from the base station to a mobile communication device, the mobile communication device comprising a short range transceiver, a processor and a display screen; and

displaying the real-time heart rate data of the user on the display screen of the mobile communication device.

2. The method according to claim 1 wherein the short range wireless transceiver of the monitoring device operates on a communication protocol using WiFi, Infrared, or ultrasound.

3. The method according to claim 1 wherein the mobile communication device is a smartphone.
