Abstract

A data processing tool for the viewing of real-time, critical patient data on remote and/or mobile devices. The tool efficiently renders graphical data on the screen of the remote device in a manner that makes it practical for the health care provider to accurately and timely review the data for the purpose of making an informed decision about the condition of the patient. Charting control is established and implemented using the latest GDI+, GAPI and PDA drawing techniques. The charting components provide landscape support, an ability to overlay patient data and patient images, zoom in/zoom out, custom variable speed scrolling, split screen support, and formatting control. The methodology operates as an asynchronous application, without sacrificing crucial processing time in the mobile/handheld device. The methodology allows the critical patient data to be streamed in real-time to the handheld device while conserving enough CPU power to simultaneously allow the end user to interact at will with the responsive display application. The methodology is structured using object oriented concepts and design patterns. Each logical tier of the methodology, from the data access objects and the charting control objects, to the user interface objects, is structured with precise interfaces. Finally, the methodology implements an IT management console that allows system managers to monitor the exchange of data between hospital systems and the primary database, including all patient data packets, notifications and alerts, connected remote devices, etc.

Claims

1. A system for the remote monitoring of patient physiological data acquired from at least one patient sensor, said patient physiological data capable of being plotted graphically versus time, the system comprising:

(a) a sensor data collection system for collecting said patient physiological data;

(b) a healthcare facility data processing and data storage system serving to process and store said patient physiological data;

(c) a first graphical data interface (GDI) system operating in conjunction with said healthcare facility data processing and data storage system, said first GDI system for conditioning said patient physiological data for transmittal across a wide area network and for reception and display on a remote data processing device;

(d) a remote data processing device operable for the reception and display of said patient physiological data received from said wide area network; and

(e) a second graphical data interface (GDI) system operating in conjunction with said remote data processing device, said second GDI for conditioning said patient physiological data for display on said remote data processing device.

2. The system of claim 1 wherein said patient physiological data comprises obstetric patient data comprising maternal uterine contraction data and fetal heart rate data.

3. The system of claim 1 wherein said patient physiological data comprises cardiopulmonary patient data comprising respiration rate data and heart rate data.

4. The system of claim 1 wherein said remote data processing device comprises a wireless device for wireless connection to said wide area network.

5. The system of claim 1 wherein said remote data processing device comprises a docking device for wired connection to said wide area network.

6. The system of claim 4 or 5 wherein said remote data processing device comprises a personal data assistant (PDA) having a display screen.

7. The system of claim 4 or 5 wherein said remote data processing device comprises a smart phone communications device having a display screen.

8. The system of claim 4 or 5 wherein said remote data processing device comprises a personal computer (PC) having a display screen.

9. The system of claim 1 wherein said wide area network comprises the publicly accessible Internet.

10. The system of claim 1 wherein said wide area network comprises a privately accessible wired computer network.

11. The system of claim 1 wherein said first graphical data interface conditions said patient physiological data by compressing said data.

12. The system of claim 1 wherein said first graphical data interface conditions said patient physiological data by identifying and selecting anomalous events within the data.

13. A method for the remote monitoring of patient physiological data acquired from at least one patient sensor, said patient physiological data capable of being plotted graphically versus time, the method comprising the steps of:

(a) collecting said patient physiological data from the patient through said at least one patient sensor;

(b) processing said patient physiological data so as to make said data amenable to storage on a digital storage device;

(c) storing said patient physiological data on said digital storage device;

(d) conditioning said patient physiological data for ease of transmission over a wide area digital network;

(e) transmitting said patient physiological data over said wide area digital network;

(f) receiving said conditioned patient physiological data from said wide area digital network with a remote data processing device, said remote data processing device having a display;

(g) reconditioning said received patient physiological data for ease of display on said remote data processing device; and

(h) displaying said reconditioned patient physiological data on the display of said remote data processing device.

14. The method of claim 13 wherein said patient physiological data comprises obstetric patient data comprising maternal uterine contraction data and fetal heart rate data.

15. The method of claim 13 wherein said patient physiological data comprises cardiopulmonary patient data comprising respiration rate data and heart rate data.

19. The method of claim 13 wherein said step of receiving said conditioned patient physiological data comprises establishing a wired data communication link between said remote data processing device and said wide area network and downloading said patient physiological data from said wide area network through said wired data communication link to said remote data processing device.

20. The method of claim 13 wherein said step of reconditioning said received patient physiological data comprises formatting said data for display on said remote data processing device, said formatting step providing a reduction in a volume of said data and a reduction in a period of time required to render said data on the display of said data processing device.

21. The method of claim 13 wherein said step of displaying said reconditioned patient physiological data comprises time sequentially displaying said data.

22. The method of claim 21 wherein said time sequential display of said data comprises a real-time display of said data.
