Abstract

A wireless bi-directional portable patient monitor incorporated into a mobile clinical information management system is disclosed. The portable patient monitor includes a communications interface to receive patient data from a wireless local area network (WLAN) within a medical care facility and transmit care parameters as needed to the wireless network (WLAN) in response. The portable patient monitor includes a processor connected to the communications interface to process the patient data and the care parameters. A display is connected to the processor to display the processed patient data to the health care provider. The monitor includes an input device connected to the processor to allow a change in the care parameters by the health care provider. The portable patient monitor is also configured to allow wireless transport on the health care provider for extended periods. The mobile clinical information management system includes a number of bedside patient monitors to connect to the patients and transmit the patient data. The system also includes the wireless network coupled to the bedside patient monitors and the portable patient monitors to improve efficiencies in the delivery of health care in the medical care facility.

Claims

1. A wireless bi-directional portable patient monitor comprising:

a communication interface to receive patient data from a server via a wireless local area network (WLAN) within a medical care facility and transmit care parameters as needed to the server via the WLAN in response thereto, the server wirelessly connected to a plurality of transceivers and configured to retrieve and store patient data from the plurality of transceivers;

a processor connected to the communication interface to process the patient data and the care parameters;

a display connected to the processor to display the processed patient data in human discernable form; and

an input device connected to the processor to allow a change in the care parameters by a health care provider.

2. The portable patient monitor of claim 1 wherein the processor decodes the patient data to process and display the patient data and encodes the care parameters to transmit the care parameters to the WLAN.

3. The portable patient monitor of claim 1 wherein the portable patient monitor is packaged within a housing that is transportable on a health care provider for extended periods.

4. The portable patient monitor of claim 1 wherein the processor is programmed to allow alarm silencing of a bedside monitor, allow adjustment of alarm parameter violation limits, and admit and discharge patients.

5. The portable patient monitor of claim 1 further comprising a speaker and microphone, and wherein the processor is programmed to process data to permit voice-over-internet protocol (IP) transfer.

6. The portable patient monitor of claim 1 further comprising a bar code scanning module and a bar code scanner, and wherein the processor is programmed to receive and compare patient data with data obtainable from a centralized database that includes pharmaceutical and patient bar codes to ensure dosage accuracy, and doctor orders.

7. The portable patient monitor of claim 1 wherein the processor is further programmed to interface with non-proprietary networked systems.

8. The portable patient monitor of claim 7 wherein the processor is further programmed to interface with infusion pumps and ventilators.

9. The portable patient monitor of claim 1 wherein the processor is further programmed to receive patient reports and diagnostic analyses prepared at other locations in the medical care facility to provide the health care provider with the patient reports and diagnostic analyses in real time.

10. The portable patient monitor of claim 1 further comprising a PDA module to provide PDA functions to the health care providers including a scheduler, reminders, to-do lists, and other PDA functions.

11. The portable patient monitor of claim 1 further comprising a microphone and a digital audio recorder module to input a record of patient medical events by the health care provider.

12. A mobile clinical information management system to decentralize patient monitoring comprising:

a server connected to a WLAN and configured to receive and transmit patient data;

a portable patient monitor having a processor connected to a communication interface coupled to the WLAN to receive and process patient data from the server and to process and transmit care parameters to the server, a display to display the patient data, and an input device to change the patient care parameters, the portable patient monitor having a configuration to allow wireless transport on a health care provider for extended periods;

a plurality of bedside patient monitors wirelessly connected to the server and configured to connect to a plurality of patients and transmit patient data to the server.

13. The system of claim 12 further comprising a plurality of portable patient monitors, each portable patient monitor assigned to a given number of patients.

14. The system of claim 12 wherein the processor further:

decodes the patient data to process and display the patient data and encodes the care parameters to transmit the care parameters to the WLAN; and

processes the patient data to display ECG and vital sign data for a selected patient on the portable patient monitor.

15. The system of claim 12 wherein the portable patient monitor is a primary monitoring device and wherein a communication interface of the portable patient monitor is compatible with an existing WLAN.

16. The system of claim 12 further comprising a speaker and microphone, and wherein the processor is programmed to:

allow alarm silencing of a bedside monitor;

admit and discharge patients;

adjust alarm parameter violation limits; and

process data to permit voice-over-internet protocol (IP) transfer.

17. The system of claim 12 further comprising:

a bar code scanning module and a bar code scanner and wherein the processor is programmed to receive patient data encoded in a patient wristband, and to compare patient data with data obtainable from pharmaceutical bar codes and a centralized database to check dosage accuracy and compliance with doctor orders; and

wherein the processor is further programmed to interface with infusion pumps and ventilators, and to receive patient reports and diagnostic analyses prepared at remote locations in the medical care facility to provide the health care provider with the patient reports and diagnostic analyses in real time.

18. The system of claim 12 wherein the portable patient monitor includes a PDA module having PDA functions that include a scheduler, reminders, and to-do lists, and further comprises a microphone and a digital audio recorder module to record an audio input by the health care provider into the microphone and record patient medical events.

19. A computer program residing in memory of a portable patient monitor to cause a processor to:

remotely interface to a server via a WLAN to acquire any patient alarms conveyed to the server by a centralized patient monitor connected to at least one bedside patient monitor;

sound an alarm if a patient alarm occurs;

allow user silencing of an alarm at the at least one patient bedside monitor via the WLAN;

allow user silencing of the alarm at the portable patient monitor; and

display patient data.

20. The computer program of claim 19 wherein the computer program further causes the processor to:

periodically check a recharged battery charge; and

display a warning if the rechargeable battery charge is low.

21. The computer program of claim 19 wherein the computer program further causes the processor to allow user adjustment of alarm parameter violation limits.

22. The computer program of claim 19 wherein the computer program further causes the processor to relay patient admission and discharge information to the WLAN.

23. The computer program of claim 19 wherein the computer program further causes the processor to process audio data from a health care provider to record medical history of a patient.

24. The computer program of claim 19 wherein the computer program further causes the processor to scan a bar code from a patient ID and compare data obtained therefrom with data on the patient from a main patient database to ensure proper medical treatment.
