Abstract

A system and method for monitoring and analyzing patient urinary output and a plurality of additional patient physiological parameters. The system comprises a plurality of patient connections and monitoring apparatus for monitoring a plurality of patient physiological parameters. The system further comprises a processor programmed to apply at least one analysis criterion to at least a signal indicative of patient urinary output. The processor further applies additionally more complex analysis criterion to a combination of patient urinary output data and at least one additional patient physiological parameter to provide an automated diagnosis of patient condition.

Claims

1. A system for monitoring and analyzing a plurality of patient physiological parameters, the plurality of patient physiological parameters comprising patient urinary output and at least one additional physiological parameter, the apparatus comprising:

a plurality of patient connections, each patient connection disposed for collection of one or more patient parameters, one of the plurality of patient connections comprising a connection for measuring patient urinary output;

a monitoring apparatus connected to each of the patient connections, the monitoring apparatus receiving a signal from each of the patient connections indicative of a patient physiological parameter;

a processor programmed to apply at least one analysis rule to at least a signal indicative of patient urinary output;

a first database in communication with the processor, the first database comprising a first plurality of analysis rules for analyzing urinary output;

a second database in communication with the processor, the second database comprising a second plurality of rules for interpreting the signal indicative of patient urinary output and at least one signal indicative a patient parameter;

wherein the processor applies at least one of the second plurality of rules to the urinary output signal and the at least one patient parameter signal.

2. The system of claim 1, further comprising a patient history database wherein a result from the application of each analysis rule is recorded.

3. The system of claim 2 further comprising a processor programmed to produce a diagnosis of patient condition based upon the results recorded in the patient history database.

4. The system of claim 3 further comprising means for modifying the provision of an external substance to the patient in relation to the diagnosis of patient condition.

5. The system of claim 4 wherein the external substance is selected from the list comprising:

nutrition, a drug, or a saline solution.

6. A method monitoring the condition of a patient, the patient connected to a plurality of patient monitoring systems, the plurality of monitoring systems comprising at least the monitoring of urine output, the method comprising:

obtaining a measurement of patient urinary output;

obtaining a measurement of at least one additional physiological parameter;

applying a basic level urinary output interpretation rule to the measurement of urinary output;

applying an advanced level urinary output interpretation rule to the measurement of urinary output and the at least one additional physiological parameter;

wherein if the basic level of urinary output interpretation rule is met, the advanced level of urinary output interpretation rule is applied and if the basic level urinary output interpretation rule is not met, an alarm signal is sent to an alarm.

7. The method of claim 6 further comprising the steps of recording the result of the application of each urinary output interpretation rule.

8. The method of claim 7 wherein the basic level urinary output interpretation rule is a time based interpretation rule.

9. The method of claim 8 wherein the time based interpretation rule is a binary determination of the measurement of urinary output over a time period.

10. The method of claim 8 further comprising applying a medium level urinary output interpretation rule to the measurement of urinary output.

11. The method of claim 10 wherein the medium level urinary output interpretation rule is a volume based interpretation rule.

12. The method of claim 11 wherein the volume based interpretation rule comprises a range of volume of desired urinary output over a specified time period.

13. The method of claim 11 wherein the advanced level urinary output interpretation rule applies a logical rule to the measurement of urinary output and the at least one additional physiological parameter.

14. The method of claim 13 wherein the at least one physiological parameter is selected from the list comprising:

ECG, blood pressure, spO2, and blood gas concentration.

15. The method of claim 13 wherein the at least one physiological parameter is selected from the list comprising:

administration of food, administration of a drug, and administration of saline.

16. The method of claim 6 further comprising:

displaying the result of the application of each interpretation rule;

determining a course of action in response to the result of the interpretation rule;

performing a treatment measure based upon the determined course of action.

17. The method of claim 16 wherein the treatment measure is the introduction of additional intravenous fluid.

18. The method of claim 16 wherein the treatment measure is the introduction of additional drug.

19. The method of claim 16 wherein determining a course of action is performed as part of an automated patient diagnosis system.

20. The method of claim 6 further comprising obtaining a user input, the user input indicative of specific interpretation rule to be applied to the measurement of urinary output and the measurement of at least one additional physiological parameter.

21. A method of monitoring a patient, the method comprising:

obtaining patient urinary output data;

obtaining an input from a user indicative of an analysis to perform on the patient urinary output data;

producing a first outcome indication by analyzing the urinary output data and a first parameter, the first parameter being selected from the list comprising the parameters of time and volume;

analyzing the urinary output data in light of at least one second parameter to produce a second outcome indication, the at least one second parameter being a physiological parameter;

wherein each of the outcome indications are recorded in a patient history and if one of the outcome indications is outside of a predefined value an alarm indication is initiated.
