Abstract

The invention provides a system for monitoring a patient that includes a sensor configured to drape around the patient'"'"'s neck. The sensor features an impedance sensor for measuring fluids, an ECG sensor for measuring cardiac activity, and a first wireless transceiver for transmitting this information. Integrated with the sensor is a computer, featuring a second wireless transceiver, video output system, and a computer processing unit (CPU). The CPU is configured to receive control signals from the first wireless transceiver that control a software program and the information related to fluids and cardiac activity. The software program renders a graphical user interface that displays the information through the video output system. The system also includes a conventional television set or mobile device that interfaces to the computer through the video output system and renders the graphical user interface.

Claims

1. A system for monitoring a patient, comprising:

a sensor configured to drape around the patient'"'"'s neck, the sensor comprising an impedance sensor for measuring fluids in the patient, an ECG sensor for measuring cardiac activity corresponding to the patient, and a first wireless transceiver for transmitting information related to fluids and cardiac activity associated with the patient;

a computer comprising a second wireless transceiver, video output system, and a CPU, the second wireless transceiver configured to receive control signals from the first wireless transceiver that control a software program operating on the CPU, and the CPU configured to render a graphical user interface that displays the information transmitted from the sensor through the video output system; and

a mobile device that interfaces to the computer through the video output system and renders the graphical user interface.

2. The system of claim 1, wherein the sensor is configured to send control signals to the CPU configured to activate the software program.

3. The system of claim 2, wherein the control signals power on the CPU.

4. The system of claim 2, wherein the control signals activate IO pins in the CPU.

5. The system of claim 1, wherein the CPU operates a second software program that automatically launches the graphical user interface on the mobile device.

6. The system of claim 5, wherein the CPU is configured to automatically launch the software program at a pre-determined time.

7. The system of claim 1, wherein the CPU operates a second software program that launches the graphical user interface when it detects that the patient has been operating their mobile device for a predetermined period of time.

8. The system of claim 1, wherein the sensor comprises a motion sensor.

9. The system of claim 8, wherein the motion sensor is an accelerometer.

10. The system of claim 8, wherein the CPU operates a second software program that launches the graphical user interface when the motion sensor detects that the patient has been sedentary for a pre-determined period of time.

11. The system of claim 8, wherein the CPU operates a second software program that launches the graphical user interface when the motion sensor detects that the patient is in motion.

12. The system of claim 1, wherein the CPU operates a second software program that launches the graphical user interface so that it interrupts graphical content displayed on the mobile device.

13. The system of claim 12, wherein the CPU operates a second software program that launches the graphical user interface so that it is displayed on a web page rendered on the mobile device.

14. The system of claim 1, wherein the ECG sensor measures a heart rate from the patient.

15. The system of claim 14, wherein the CPU operates a second software program that launches the graphical user interface when the heart rate exceeds a predetermined value.

16. The system of claim 14, wherein the ECG sensor measures a heart rate variability from the patient.

17. The system of claim 16, wherein the CPU operates a second software program that launches the graphical user interface when the heart rate variability exceeds a predetermined value.

18. The system of claim 1, wherein the impedance sensor measures a level of fluids from the patient.

19. The system of claim 18, wherein the CPU operates a second software program that launches the graphical user interface when the level of fluids exceeds a predetermined value.
