## Abstract

A system and method for comprehensive remote monitoring of a user's vital signs and bodily functions includes a wearable monitor in bi-directional communication with a gateway element that communicates with one or more external devices to allow remote access to user vital sign and bodily function information.

## Claims

### Claim 1

A system to monitor a user's health comprising:
a monitor element securable to and in contact with the user's body at any desired position, the monitor element including at least one sensor providing information associated with health of the user, the sensor providing information associated with one or more of:
user heart rate;
user respiration rate;
user blood pressure;
user oxygen level;
the sensor including:
at least one light emitting diode;
at least one light sensor facing the user, wherein the at least one light sensor provides light sensing information based on light reflected from the at least one light emitting diode off the user's skin; and
a bed sensor configured to provide position information associated with a position of the user in a bed;
a central station in communication with the monitor element, wherein the information associated with health of the user and position information are received by the central station via radio frequency communication, wherein the central station analyzes the information associated with health of the user and position information and determines whether intervention is appropriate, based at least one of:
at least one heartrate threshold;
at least one respiration rate threshold;
at least one blood pressure threshold based on at least the light sensing information; and
at least one oxygen level threshold.

### Claim 2 (depends on 1)

The system of claim 1, wherein the information associated with the health of the user is stored in a memory associated with the central station.

### Claim 3 (depends on 1)

The system of claim 1, wherein the information associated with the health of the user further comprises information associated with:
user weight;
user activity; and
user sleep quality.

### Claim 4 (depends on 1)

The system of claim 1, wherein the monitor element comprises an adhesive element positioned on an inner surface thereof for contact with the user's skin to position the monitor element on the user's body.

### Claim 5 (depends on 4)

The system of claim 4, wherein the adhesive element includes an alignment element positioned to aid in positioning of the monitor element on the user's body.

### Claim 6 (depends on 1)

The system of claim 1, wherein the monitor element comprises a plurality of electrodes.

### Claim 7 (depends on 6)

The system of claim 6, wherein a pair of electrodes are provided on a first end of the monitor element and a third electrode is provided on a second end of the monitor element, opposite the first end.

### Claim 8 (depends on 7)

The system of claim 7, wherein the pair of electrodes are provided side by side.

### Claim 9 (depends on 8)

The system of claim 8, wherein the third electrode is spaced a predetermined distance from the pair of electrodes.

### Claim 10 (depends on 9)

The system of claim 9, wherein the pair of electrodes and third electrode are positioned to provide ECG information.

### Claim 11 (depends on 7)

The system of claim 7, wherein the first end of the monitor element is connected to the second end of the monitor element via a flexible bridge element such that the first end of the monitor element and second end of the monitor element are movable with the user's skin relative to each other.

### Claim 12 (depends on 1)

The system of claim 1, wherein the position information indicates a presence of the user in the bed.

### Claim 13 (depends on 1)

The system of claim 1, wherein the light sensing information and ECG information are used by the monitor to determine the user blood pressure.

### Claim 14 (depends on 1)

The system of claim 1, wherein the light sensing information and ECG information are transmitted from the monitor element to the central station and the user blood pressure is determined at the central station.

### Claim 15 (depends on 1)

The system of claim 1, further comprising an alert device in wireless communication with the central station.

### Claim 16 (depends on 15)

The system of claim 15, wherein the alert device comprises an alert button, wherein the alert device transmits an alert signal to the central station when the alert button is actuated.

### Claim 17 (depends on 16)

The system of claim 16, wherein the central station transmits the alert signal to emergency personnel.

### Claim 18 (depends on 16)

The system of claim 16, wherein the alert device provides two way communication with the central station.

### Claim 19 (depends on 1)

The system of claim 1, wherein the position information is used by the central station to provide mobility information associated with the user.

### Claim 20 (depends on 1)

The system of claim 1, wherein the position information is used by the central station to provide sleep activity information associated with the user.

### Claim 21 (depends on 1)

The system of claim 1, wherein the monitor element checks the information associated with health of the user for errors prior to sending the information associated with health of the user to central station and does not send the information associated with health of the user to the central station when errors are detected.

### Claim 22 (depends on 1)

The system of claim 1, wherein the monitoring device is in two way communication with the central station.
