Abstract

System (15) for managing related-patient parameters provided by at least one monitoring device (11 a, 11 b), the system comprising means for connecting said system to the monitoring device (11 a; 11 b); means for capturing, through the connection with the monitoring device, at least one patient-related parameter selected from a set of patient-related parameters provided by the monitoring device (11 a; 11 b); means for adapting the captured patient-related parameter to a predetermined parameter format; and means for managing the adapted patient-related parameter. The provision of adapting means allows managing data provided by any type of monitoring device.

Claims

1. A method for managing, in a computer system, patient-related parameters provided by at least one monitoring device, the method comprising the steps of:

A) connecting the computer system to said at least one monitoring device;

B) capturing, through the connection with the monitoring device, one or more physiological patient-related parameters selected from a set of patient-related parameters provided by said at least one monitoring device, wherein the capturing comprises;

requesting continuously signal values for the one or more physiological patient-related parameters during a defined period of time;

recording a time of capture for each signal value requested during the defined period of time;

obtaining a delay of the at least one monitoring device in sending the signal values; and

determining an actual time of capture for each signal value based at least on the time of capture for each signal value and the delay obtained for the at least one monitoring device;

C) adapting each of the captured one or more physiological patient-related parameters to a predetermined parameter format to define a virtual parameter, said virtual parameter being a representation in the computer system of the captured one or more physiological patient-related parameters, which univocally represents a parameter independently of its device of origin; and

D) managing the adapted one or more physiological patient-related parameters, wherein the managing comprises synchronizing each signal value captured for the one or more physiological patient-related parameters from said at least one monitoring device with signal values captured for one or more other physiological patient-related parameters captured from another monitoring device using the actual time of capture such that the synchronization takes account of the delay from the at least one monitoring device.

2. A method according to claim 1, wherein said one or more physiological patient-related parameters are provided by at least a first monitoring device and a second monitoring device.

3. A method according to claim 2, wherein the one or more physiological patient-related parameters captured from said first monitoring device and said second monitoring device are synchronized.

4. A method according to claim 3, wherein said captured one or more physiological patient-related parameters are synchronized taking into account a first delay for sending data of said first monitoring device and a second delay for sending data of said second monitoring device.

5. A method according to claim 4, wherein said first delay or said second delay is experimentally obtained.

6. A method according to claim 1, wherein steps (B) to (D) are repeated after predetermined periods of time.

7. A method according to claim 1, further comprising a step (E) of obtaining, from a user input, the monitoring device to be connected.

8. A method according to claim 1, further comprising a step of adapting the communication protocols of the computer system and the monitoring device for establishing a connection between them.

9. A method according to claim 1, wherein step (D) of managing the adapted one or more physiological patient-related parameters comprises a sub-step (D.1) of storing said adapted one or more physiological patient-related parameters in a first repository.

10. A method according to claim 9, wherein, in sub-step (D.1), the adapted one or more physiological patient-related parameters stored in the first repository comprises the adapted one or more physiological patient-related parameters and a time of capturing the adapted one or more physiological patient-related parameters.

11. A method according to claim 10, wherein the adapted one or more physiological patient-related parameters stored in the first repository further comprises video and audio signals obtained at the time of capturing the adapted one or more physiological patient-related parameters.

12. A method according to claim 9, wherein, in sub-step (D.1), the adapted one or more physiological patient-related parameters is stored as objects in accordance with Digital Imaging and Communications in Medicine (DICOM) standard.

13. A method according to claim 12, wherein step (D) of managing the adapted one or more physiological patient-related parameters comprises a sub-step (D.2) of displaying said adapted one or more physiological patient-related parameters.

14. A method according to claim 13, wherein step (D) of managing the adapted one or more physiological patient-related parameters comprises a sub-step (D.3) of distributing said adapted one or more physiological patient-related parameters to at least another computer system.

15. The method according to claim 1, wherein the one or more physiological patient-related parameters is selected from the group consisting of electrocardiogram signals, pulse oximetry signals, artificial respirator pressure signals, airflow signals, arterial pressure signals, and CO₂ signals.

16. The method according to claim 1, wherein the captured one or more physiological patient-related parameters comprise a sequence of data points measured from a patient at successive points in time spaced at uniform time intervals.

17. The method according to claim 1, wherein the one or more physiological patient-related parameters include values captured over a defined period of time.

23. A computer program product comprising a non-transitory storage medium having program instructions embodied in the non-transitory storage medium, the program instructions when executed cause the computer system to perform the method of claim 1.

18. A system for managing patient-related parameters comprising:

a plurality of monitoring devices;

a router;

a communication network;

an electronic device having a display; and

a server connected to said plurality of monitoring devices and configured to;

capture through the connection with the monitoring devices, at least one physiological patient-related parameter selected from a set of patient-related parameters provided by the monitoring devices, wherein the capture comprises;

requesting continuously signal values for the at least one physiological patient-related parameter during a defined period of time;

recording a time of capture for each signal value requested during the defined period of time;

obtaining a delay of the monitoring devices in sending the signal values; and

determining an actual time of capture for each signal value based at least on the time of capture for each signal value and the delay obtained for the monitoring devices; and

adapt the captured at least one physiological patient-related parameter to a predetermined parameter format to define a virtual parameter, said virtual parameter being a representation in the system of the captured at least one physiological patient-related parameter, which univocally represents a parameter independently of its device of origin, and

manage the adapted at least one physiological patient-related parameter by synchronizing each signal value captured for the at least one physiological patient-related parameter from said monitoring devices with signal values captured for at least one other physiological patient-related parameters captured from another monitoring device using the actual time of capture such that the synchronization takes account of the delay from the monitoring devices

wherein said server is connected to the communication network through the router, and the electronic device having said display is connected to the communication network, such that real-time remote monitoring of a patient is possible.
