Abstract

An integrated vitals device capable of acquiring multiple data streams, allowing for comprehensive measurement of whole health status using a single, compact device. This allows for simplification of traditional healthcare delivery where multiple devices are required for acquisition of vital signs. A sensor stack up, occupying the approximate physical footprint and volume allows this approach to be possible. This application describes how these simultaneous vitals data streams can be acquired using an integrated device with small mass and volume.

Claims

1. An integrated vitals sensor comprising:

a reflective pulse oximeter;

a single lead EKG;

a first thermistor, wherein the first thermistor is configured to detect core body temperature; and

a double-sided adhesive gel pad to permit the sensor to be worn in contact with skin, wherein a color of a first side of the adhesive gel pad is different than a color of a second side of the adhesive gel pad.

2. The sensor of claim 1, further comprising a second thermistor, wherein the first thermistor and the second thermistor are arranged in a vertical stack up configuration to measure a heat gradient from a wearer'"'"'s body.

3. The sensor of claim 1, wherein the at least a first portion of the double-adhesive gel pad has a dark color that is configured to prevent external light from reaching the sensor.

4. The sensor of claim 1, further comprising at least one resistive heater, wherein the at least one resistive heater, the single lead EKG, the first thermistor, and the reflective pulse oximeter are integrated into a single circuit board.

5. The sensor of claim 1, further comprising a plurality of resistors arranged in a radial configuration around the reflective pulse oximeter.

6. The sensor of claim 1, wherein the sensor is further configured to detect at least one of heart rate, respiratory rate, EKG, and SpO2.

7. The sensor of claim 2, wherein the reflective pulse oximeter is located between the first thermistor and the second thermistor.

8. An integrated vitals sensor comprising:

a reflective pulse oximeter;

a single lead EKG;

a first thermistor, wherein the first thermistor is configured to detect core body temperature; and

a double-sided adhesive gel pad, wherein at least a first portion of the gel pad has a dark color that is configured to prevent external light from reaching the sensor.

9. The sensor of claim 8, further comprising a second thermistor, wherein the first thermistor and the second thermistor are arranged in a vertical stack up configuration to measure a heat gradient from a wearer'"'"'s body.

10. The sensor of claim 8, wherein the double-sided adhesive gel pad permits the sensor to be worn in contact with skin.

11. The sensor of claim 8, wherein a color of a first side of the gel pad is different than a color of a second side of the gel pad.

12. The sensor of claim 8, further comprising at least one resistive heater, wherein the at least one resistive heater, the single lead EKG, the first thermistor, and the reflective pulse oximeter are integrated into a single circuit board.

13. The sensor of claim 8, further comprising a plurality of resistors arranged in a radial configuration around the reflective pulse oximeter.

14. The sensor of claim 8, wherein the sensor is further configured to detect at least one of heart rate, respiratory rate, EKG, and SpO2.

15. The sensor of claim 9, wherein the reflective pulse oximeter is located between the first thermistor and the second thermistor.
