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 electrocardiogram (ECG) information from the patient, a web server configured to support a secure communications connection and further configured to exchange information via the secure communications connection, and at least one first processor configured to;

receive the acquired ECG information from the one or more sensors, transmit the ECG information for information exchange via the secure communications connection; and

a remote interface device comprising;

a web browser configured to receive information via the secure communications connection, and at least one second processor configured to;

establish a communication link between the external defibrillator monitor and the remote interface device, establish the secure communications connection between the web server of the external defibrillator monitor and the web browser, send a request to the web server for the ECG information, receive, in response to the request via the secure communications connection, a first transmission representing at least a first portion of the ECG information, and receive, in response to the request via the secure communications connection, one or more second transmissions representing at least a second portion of the ECG information, the one or more second transmissions received by the at least one second processor continuously after the first transmission is received and without requiring a further request to the web server being sent by the at least one second processor.

2. The system of claim 1, wherein a latency of at least one of the first transmission and the one or more second transmissions of the ECG information from the external defibrillator monitor to the remote interface device is approximately 40 to 200 milliseconds.

3. The system of claim 1, wherein at least one of the first transmission and the one or more second transmissions represents between 40 to 200 milliseconds of the ECG information.

4. The system of claim 1, wherein the first transmission and the one or more second transmissions are sent between 40 to 200 milliseconds apart.

5. The system of claim 1, wherein the secure communications connection is configured to provide full-duplex communication between the external defibrillator monitor and the remote interface device.

6. The system of claim 1, wherein the first transmission comprises a first packet comprising a header and the first portion of the ECG information and the one or more second transmissions comprise one or more second packets comprising a header and the second portion of the ECG information.

7. The system of claim 6, wherein each of the first packet and the one or more second packets represent approximately 120 milliseconds of the ECG information.

8. The system of claim 6, wherein the at least one first processor is configured to transmit the one or more second packets at least once approximately every 120 milliseconds after transmitting the first packet or a previous response.

9. The system of claim 1, wherein the secure communications connection is configured to provide encrypted, full-duplex communication between the external defibrillator monitor and the remote interface device.

10. The system of claim 9, wherein the secure communications connection is configured to be encrypted using secure socket layer (SSL) encryption.

11. The system of claim 9, wherein the secure communications connection is configured to detect if a user agent is configured to use a proxy when connecting to the secure communications connection.

12. The system of claim 11, wherein the secure communications connection is configured to automatically fail if unencrypted information flows through an unsecured proxy server attempting to connect to the external defibrillator monitor via the secure communications connection.

13. The system of claim 12, wherein the user agent is the remote interface device.

14. The system of claim 1, 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.

15. The system of claim 14, wherein the at least one second processor is configured to accept a user command to suspend the second alarm for a period of time.

16. 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 electrocardiogram (ECG) information from the patient, a web server configured to support a secure connection and further configured to exchange information via the secure connection, and at least one first processor configured to;

receive the acquired ECG information from the one or more sensors, transmit the ECG information for information exchange via the secure connection; and

a remote interface device comprising;

a web browser configured to receive information via the secure connection, and at least one second processor configured to;

establish a communication link between the external defibrillator monitor and the remote interface device, establish the secure connection between the web server of the external defibrillator monitor and the web browser, and receive a first transmission representing at least a first portion of the ECG information, wherein a latency of the transmission of the ECG information from the external defibrillator monitor to the remote interface device is 40 to 200 milliseconds.
