Abstract

A patient hydration system with an infusion subsystem responsive to a source of hydration fluid for infusing the patient with hydration fluid. A urine output measurement subsystem determines the amount of urine output by the patient. A setting is received corresponding to an amount of urine to be output by the patient. When or after the urine output measurement subsystem indicates the set amount of urine has been output by the patient, the infusion subsystem is controlled to administer hydration fluid to the patient based on the patient'"'"'s further urine output.

Claims

1. A patient hydration system comprising:

an infusion subsystem responsive to a source of hydration fluid for infusing the patient with hydration fluid;

a urine output measurement subsystem for determining the amount of urine output by the patient; and

a controller, responsive to the urine output measurement subsystem and configured to;

receive a setting corresponding to an amount of urine to be output by the patient, and

when or after said urine output measurement subsystem indicates said set amount of urine has been output by the patient, control the infusion subsystem to administer hydration fluid to the patient based on the patient'"'"'s further urine output.

2. The system of claim 1 in which the urine output measurement subsystem includes a urine collection chamber connected to the patient.

3. The system of claim 2 in which the urine output measurement subsystem further includes a weighing mechanism for weighing the urine reservoir.

4. The system of claim 1 in which the controller is configured, based on a setting, to administer hydration fluid at a rate equal to, less than, or greater than the rate of urine output by the patient.

5. The system of claim 1 in which the infusion subsystem includes a pump.

6. The system of claim 1 further including:

a console for mounting on an IV pole;

a first attachment mechanism extending from the console for hanging a urine collection chamber;

a first weighing device associated with the console and responsive to the first attachment;

a second attachment extending from the console for hanging a source of hydration fluid;

a second weighing device associated with the console and responsive to the second attachment for weighing the source of hydration fluid;

an infusion pump integrated with the console and configured to pump hydration fluid from the source of hydration fluid to the patient; and

the controller is responsive to the first and second weighing devices and configured to control the infusion pump to hydrate the patient based on the patient'"'"'s urine output.

7. A patient hydration method for a patient to whom a diuretic has been administered, the method comprising:

setting a patient hydration subsystem connected to the patient with an infusion subsystem responsive to a source of hydration fluid and a urine output measurement subsystem for determining the amount of urine output by the patient to;

infuse the patient with hydration fluid after a predetermined amount of urine is output by the patient, and

thereafter adjust the infusion rate of the infusion subsystem based on the urine output of the patient.

8. The method of claim 7 in which the patient'"'"'s urine output and the source of hydration fluid are weighed.

9. The method of claim 8 in which controlling the hydration fluid infusion rate includes controlling an infusion pump.

10. A patient hydration method comprising:

setting a desired patient urine output;

automatically determining the amount of urine output by the patient; and

when or after the set desired patient urine output has been output by the patient, automatically administering hydration fluid to the patient based on the patient'"'"'s urine output thereafter.

11. A patient monitoring system comprising:

a urine output measurement subsystem for automatically determining the amount of urine output by the patient; and

a controller, responsive to the urine output measurement subsystem and configured to;

receive a setting corresponding to an amount of urine desired to be output by the patient, and

when or after said urine output measurement subsystem indicates said set amount of urine has been output by the patient, taking an action.

12. The system of claim 11 in which said action is activating an alarm.

13. The system of claim 11 in which said action is controlling an infusion subsystem to administer hydration fluid to the patient based on the patient'"'"'s urine output.

14. The system of claim 11 in which said action includes displaying a urine output rate.

17. The method of claim 14 in which the action is controlling a patient infusion subsystem to administer hydration fluid to the patient based on the patient'"'"'s urine output.

15. A patient monitoring method comprising:

setting a desired amount of urine to be output by the patient;

automatically determining the amount of urine output by the patient; and

when the set amount of urine has been output by the patient, automatically taking an action.

16. The method of claim 15 in which the action is activating an alarm.

18. The method of claim 15 in which the action is displaying the urine output rate and administering hydration fluid at said rate.

19. A patient hydration system comprising:

an infusion subsystem responsive to a source of hydration fluid for infusing the patient with hydration fluid;

a urine output measurement subsystem for determining the amount of urine output by the patient; and

a controller, responsive to the urine output measurement subsystem and configured to;

receive a setting corresponding to a desired amount of urine to be output by the patient, and

when or after said urine output measurement subsystem indicates said set amount of urine has been output by the patient, taking an action.

20. The system of claim 19 in which said action is activating an alarm.

21. The system of claim 19 in which said action is controlling the infusion subsystem to administer hydration fluid to the patient based on the patient'"'"'s urine output.
