Abstract

A data-processing tool for displaying real-time patient data on remote and/or mobile devices. The tool renders graphical data on the screen of the remote device in a manner that makes it practical for the health care provider to review the data. 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, allowing 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. 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 operable to (i) process and store said patient physiological data, wherein the processing includes generating multi-channel patient physiological data from the collected patient physiological data (ii) process and store clinical information system (CIS) data collected from external repositories and provide the physiological data and the CIS data to external repositories and devices, and (iii) provide an IT management console for monitoring exchanges of data between external repositories and devices and said healthcare facility data processing and storage system;

(c) a first graphical application program interface (API) system configured to operate in conjunction with said healthcare facility data processing and data storage system, said first graphical API for conditioning said patient physiological data for streaming across a cellular network and for reception and display on a handheld data processing device by compressing said data;

(d) a handheld data processing device operable for the reception and display of said multi-channel patient physiological data received from said cellular network, the display of multi-channel patient physiological data comprising simultaneously displaying two or more unique data sets for one patient in real-time, one data set configured for display in a software-generated semi-transparent overlay such that each data set is legibly viewable, and wherein the patient physiological data is displayed in real-time when the handheld data processing device is online and the patient physiological data is cached for future display when the handheld data processing device is offline; and

(e) a second graphical API system operating in conjunction with said handheld data processing device, said second graphical API system operable to condition said patient physiological data for display on said remote data processing device by formatting said data to optimize data presentation for reduced size presentation of said data on said display screen in said handheld 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 handheld data processing device,

wherein said handheld data processing device is configured to buffer said data and display a real-time section of said data as the real-time portion is streamed and a historical section of said data stored in said buffer, wherein a displayed section of said data is collected over a smaller period of time than all of the data stored in the buffer.

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 handheld data processing device comprises a docking device for wired connection to said first graphical API.

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

6. The system of claim 1 wherein said cellular network is connected to the first graphical API via a privately accessible wired computer network.

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

18. The system of claim 1, wherein the handheld data processing device is operable to overlay a partially transparent image of the patient on the displayed section of said data, wherein said transparent image is used for recognizing the patient'"'"'s physical appearance and for verifying an environment within which the patient physiological data was acquired.

19. The system of claim 1, wherein the handheld data processing device operable to display said data in landscape mode and in portrait mode.

20. The system of claim 19, wherein the displayed section of said data corresponds to a longer time period of patient data when the data is displayed in landscape mode than when the data is displayed in portrait mode.

21. The system of claim 1, wherein the second graphical API is configured to operate asynchronously with the first graphical API.

22. The system of claim 1, wherein the handheld data processing device is configured to present screen controls on the screen of the device, and wherein the screen controls are operable to move the displayed section of data backward and forward through the historical section of said data.

8. 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 digital for 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 wireless network by compressing said data;

(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-handheld data processing device, said remote-handheld data processing device having a display for displaying said patient physiological data in said display or in a software-generated semi-transparent overlay within said display;

(g) reconditioning said received patient physiological data for ease of display on said remote data processing device, wherein said step of reconditioning said received patient physiological data comprises formatting said data to optimize data presentation for reduced size presentation of said data on said display in said remote data processing device, said formatting step (i) 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 handheld data processing device and (ii) generating multi-channel patient physiological data from said received patient physiological data for simultaneous display in the display screen or in the software-generated semi-transparent overlay within said display; and

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

9. The method of claim 8 wherein said patient physiological data comprises obstetric patient data comprising maternal uterine contraction data and fetal heart rate data.

10. The method of claim 8 wherein said patient physiological data comprises cardiopulmonary patient data comprising respiration rate data and heart rate data.

11. The method of claim 8 wherein said step of conditioning said patient physiological data comprises identifying and selecting anomalous events within the data.

12. The method of claim 8 wherein said step of receiving said conditioned patient physiological data comprises establishing a wired data communication link between said remote-handheld 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-handheld data processing device.
