Abstract

A centralized patient monitoring system configured to enable each of a plurality of technicians to generally simultaneously monitor multiple patients is disclosed herein. The centralized patient monitoring system includes a computer adapted to receive patient data from the monitored patients, and a display configured to visually convey the patient data. The centralized patient monitoring system also includes a directional speaker configured to selectively generate a localized alarm in order to audibly alert one of the technicians when a monitored patient requires attention in a manner that is generally imperceptible to the other technicians.

Claims

1. A centralized patient monitoring system configured to enable each of a plurality of technicians to generally simultaneously monitor multiple patients comprising:

a computer adapted to receive patient data from the monitored patients;

a display connected to the computer, said display configured to visually convey the patient data; and

a directional speaker connected to the computer, said directional speaker being configured to selectively generate a localized alarm to audibly alert one of said plurality of technicians when one of the monitored patients requires attention, wherein said localized alarm is generally imperceptible to the other of said plurality of technicians.

2. The centralized patient monitoring system of claim 1, wherein said localized alarm comprises a narrow beam of audible sound waves.

3. The centralized patient monitoring system of claim 1, wherein said computer includes a fault detection algorithm adapted to assess a directional speaker operational status.

4. The centralized patient monitoring system of claim 1, further comprising a conventional speaker adapted to selectively generate a universal alarm.

5. The centralized patient monitoring system of claim 1, wherein said computer comprises a plurality of computers each configured to selectively generate an individual alarm signal.

6. The centralized patient monitoring system of claim 5, further comprising an audio mixer configured to receive the individual alarm signals from each of the plurality of computers, to combine the individual alarm signals into a single composite alarm signal, and to transmit the composite alarm signal to the directional speaker.

7. The centralized patient monitoring system of claim 6, wherein said audio mixer includes a fault detection algorithm adapted to assess a directional speaker operational status.

8. The centralized patient monitoring system of claim 1, further comprising an audio sensor adapted to assess a directional speaker operational status.

9. A centralized patient monitoring system configured to enable each of a plurality of technicians to generally simultaneously monitor multiple patients comprising:

a computer adapted to receive patient data from a plurality of monitored patients, and to analyze the patient data in order to identify any of said plurality of monitored patients that require attention;

a display connected to the computer, said monitor configured to visually convey the patient data; and

a directional speaker connected to the computer, said directional speaker being configured to selectively to generate a localized alarm in response to said patient data analysis;

wherein said localized alarm comprises a narrow beam of audible sound waves directed at one of the plurality of technicians.

10. The centralized patient monitoring system of claim 9, wherein said localized alarm is configured to audibly alert said one of the plurality of technicians, and wherein said localized alarm is configured to be generally imperceptible to the other of the plurality of technicians.

11. The centralized patient monitoring system of claim 9, wherein said computer includes a fault detection algorithm adapted to assess a directional speaker operational status.

12. The centralized patient monitoring system of claim 9, further comprising a conventional speaker adapted to selectively generate a universal alarm.

13. The centralized patient monitoring system of claim 9, wherein said computer comprises a plurality of computers each configured to selectively generate an individual alarm signal.

14. The centralized patient monitoring system of claim 13, further comprising an audio mixer configured to receive the individual alarm signals from each of the plurality of computers, to combine the individual alarm signals into a single composite alarm signal, and to transmit the composite alarm signal to the directional speaker.

15. The centralized patient monitoring system of claim of claim 9, further comprising an audio sensor adapted to assess a directional speaker operational status.

16. A method for enabling each of a plurality of technicians to generally simultaneously monitor multiple patients comprising:

collecting patient data from a plurality of monitored patients;

implementing a computer to analyze the patient data;

implementing a directional speaker to selectively generate a localized alarm in response to said patient data analysis, wherein the localized alarm comprises a narrow beam of audible sound waves; and

directing the narrow beam of audible sound waves at one of the plurality of technicians such that said one of the plurality o f technicians can be audibly alerted in a manner that is generally imperceptible to the other of the plurality of technicians.

17. The method of claim 16, further comprising visually conveying the patient data.

18. The method of claim 16, further comprising assessing the operational status of the directional speaker.

19. The method of claim 18, further comprising generating a universal alarm if the directional speaker is not operational.
