Abstract

A remote interface system according to some embodiments includes one or more patient monitoring devices having one or more sensors for patient monitoring, one or more first processors to receive information from the sensors and generate patient data based thereon, a web server, a first communication system, and a first screen to display a representation of at least a first portion of the patient data, and a remote interface device including a second communication system, a second screen, one or more second processors, an application executed by the one or more second processors and configured to detect a presence of the first communication system, establish a communication link between the first and second communication systems, establish a reliable connection channel (e.g. secure websocket connection) with the web server, receive the patient data via the connection, and display at least a second portion of the patient data on the second screen.

Claims

1. A remote interface system for medical applications, the remote interface system comprising:

an external defibrillator monitor comprising;

one or more sensors configured for physical attachment to a patient and to acquire ECG information from the patient,

a web server configured to support a secure websocket connection,

a first communication system communicatively coupled with the web server for exchanging information via the secure websocket connection,

a first screen configured to display a representation of at least a first portion of the ECG information, and

at least one first processor configured to;

receive the acquired ECG information from the one or more sensors,

transmit the ECG information to the first communication system for information exchange via the secure websocket connection; and

a remote interface device comprising;

a web browser configured to receive information via the secure websocket connection,

a second communication system communicatively coupled with the web browser,

a second screen configured to display information sent through the second communication system;

at least one second processor configured to;

establish a communication link between the first and second communication systems,

establish the secure websocket connection between the web server of the external defibrillator monitor and the web browser,

send a first request to the web server for the ECG information,

receive a transmission representing the ECG information in response to the first request via the secure websocket connection, and

cause the second screen to display a representation of at least a second portion of the ECG information, the second portion of the ECG information comprising historical data other than data simultaneously displayed on the first screen,

wherein the at least one second processor is configured to produce a first alarm initiated from the external defibrillator monitor and initiate a second alarm at the remote interface device based on the first alarm, and

wherein the at least one second processor is configured to accept a user command to suspend the second alarm for a period of time.

2. The remote interface system of claim 1, wherein the period of time is configurable by a user.

3. The remote interface system of claim 1, wherein the communication link is a direct communication link that does not travel over any wires outside of the external defibrillator monitor and the remote interface device.

4. The remote interface system of claim 1, wherein at least a portion of the communication link includes a wired network.

5. The remote interface system of claim 1, wherein at least one of the external defibrillator monitor and the remote interface device is portable.

6. The remote interface system of claim 1, wherein the at least one second processor is configured to receive the ECG information via the secure websocket connection in packets each representing between 40 and 200 milliseconds of the ECG information.

7. The remote interface system of claim 1, wherein the ECG information includes at least one of ECG waveforms, reports of ECG, and results of ECG analyses.

8. The remote interface system of claim 1, wherein packets of the ECG information sent by the web server to the remote interface device are structured according to Javascript Object Notation (JSON) protocol.

9. The remote interface system of claim 1, wherein the remote interface device is configured to display the second portion of the ECG information simultaneously in two or more locations on the second screen.

10. The remote interface system of claim 1, wherein the first portion of the ECG information is not the same as the second portion of the ECG information, and wherein the remote interface device is configured to show the second portion of the ECG information simultaneously with the external defibrillator monitor showing the first portion of the ECG information.

11. The remote interface system of claim 1, wherein the patient is a first patient, the secure websocket connection is a first secure websocket connection, and the ECG information is a first ECG information, the remote interface system further comprising a second external defibrillator monitor comprising:

a second set of one or more sensors configured for physical attachment to a second patient and to acquire second ECG information from the second patient,

a second web server configured to support a second secure websocket connection,

a third communication system communicatively coupled with the second web server for exchanging information via the second secure websocket connection, and

a third screen configured to display a representation of at least a first portion of the second ECG information; and

wherein the at least one second processor is further configured to;

establish a second communication link between the second and third communication systems,

establish the second secure websocket connection between the second web server of the second external defibrillator monitor and the web browser,

receive the second ECG information via the second secure websocket connection, and

cause a fourth screen to display a representation of at least the first portion of the second ECG information.

12. The remote interface system of claim 11, wherein the at least one second processor is configured to display the at least the first portion of the second ECG information on the second screen simultaneously with displaying the at least the second portion of the first ECG information on the second screen.

13. The remote interface system of claim 12, wherein the at least the second portion of the first ECG information is displayed in a first data window on the second screen, and wherein the at least the first portion of the second ECG information is displayed in a second data window on the second screen, and wherein the at least one second processor is further configured to permit one or both of the first data window and the second data window to be repositioned on the second screen.

14. The remote interface system of claim 13, wherein the at least one second processor is further configured to permit, during use of the remote interface system, reassignment of the first data window to display of the at least the first portion of the second ECG information.

15. The remote interface system of claim 14, wherein the second screen comprises a first monitor and a second monitor, and wherein the first data window is on the first monitor and the second data window is on the second monitor.

16. The remote interface system of claim 13, wherein the at least one second processor is further configured to permit one or both of the first data window and the second data window to be repositioned on the second screen via a drag-and-drop process.

17. The remote interface system of claim 1, wherein the at least one second processor is further configured to request frame software from the web server, wherein the frame software governs number and position of display windows on the second screen, wherein the request for the frame software specifies the number and position of the display windows on the second screen.

18. The remote interface system of claim 17, wherein the number and position of the display windows is determined based on a default selection.

19. The remote interface system of claim 18, wherein the number and position of the display windows is determined based on a configuration file on the remote interface device.

20. The remote interface system of claim 1, wherein each transmission representing the ECG information in response to the first request via the secure websocket connection is received at a fixed interval after the first request or after a previous response.
