Abstract

In one embodiment, a system for tracking and reversing accidental overdose includes a patient monitoring system configured to monitor a patient parameter that provides an indication as to whether or not the patient is overdosing, an alert system configured to activate when the patient parameter falls below an established threshold, and a reversal agent delivery system configured to automatically administer a reversing agent that counteracts the effects of an analgesic medication being administered to the patient when the patient parameter falls below the established threshold.

Claims

1. A system for tracking and reversing accidental overdose because of administration of an analgesic medication, the system comprising:

a patient monitoring system configured to monitor a patient parameter that provides an indication as to whether or not the patient is overdosing;

an alert system configured to activate when the patient parameter falls below an established threshold; and

a reversal agent delivery system configured to automatically administer a reversing agent that counteracts the effects of the analgesic medication when the patient parameter falls below the established threshold.

2. The system of claim 1, wherein the patient monitoring system is configured to monitor a patient parameter indicative of patient respiration.

3. The system of claim 1, wherein the patient monitoring system is configured to monitor the patient'"'"'s respiration rate.

4. The system of claim 3, wherein the patient monitoring system comprises a belt that wraps around the torso of the patient.

5. The system of claim 1, wherein the alert system is configured to activate an alarm that alerts an attending staff member or physician that the patient parameter has fallen below the established threshold.

6. The system of claim 5, wherein the alert system is further configured to provide a warning to the patient that a reversal agent will be administrated to the patient unless the patient performs a required task that communicates to the system that the patient is alert.

7. The system of claim 1, wherein the reversal agent delivery system is configured to automatically administer an opioid antagonist to the patient.

8. The system of claim 1, wherein the reversal agent delivery system comprises a reservoir that contains a single dose of reversal agent.

9. The system of claim 8, wherein the reservoir comprises a syringe from which the reversal agent can be expelled.

10. The system of claim 8, wherein the reversal agent delivery system further comprises a reservoir that contains an intravenous liquid that can be administered after the reversal agent is administered to ensure the reversal agent reaches the patient.

11. The system of claim 1, wherein the reversal agent delivery system comprises two reservoirs, wherein each contains a single dose of reversal agent that can be separately administered to the patient.

12. The system of claim 1, further comprising an analgesic delivery system configured to administer the analgesic medication to the patient.

13. The system of claim 12, wherein the system is configured to interrupt administration of analgesic medication to the patient when the patient parameter falls below an established threshold.

14. A non-transitory computer-readable medium that stores an overdose tracking and reversing program comprising:

logic configured to determine if a patient parameter has fallen below an established threshold because of administration of an analgesic medication;

logic configured to activate an alert when the patient parameter falls below the established threshold; and

logic configured to activate a reversal agent delivery system to automatically administer a reversing agent that counteracts the effects of the analgesic medication when the patient parameter falls below the established threshold.

15. The computer-readable medium of claim 14, wherein the logic configured to determine is configured to determine if the patient'"'"'s respiration rate has fallen below an established threshold.

16. A method for tracking and reversing accidental overdose, the method comprising:

monitoring a patient parameter to determine whether or not the patient is overdosing;

if the patient parameter falls below an established threshold, activating an alert and automatically administering a dose of reversal agent to the patient that counteracts the effects of the analgesic medication.

17. The method of claim 16, wherein monitoring comprises monitoring the patient'"'"'s respiration rate.

18. The method of claim 16, wherein activating an alert comprises activating an alarm that alerts an attending staff member or physician that the patient parameter has fallen below the established threshold.

19. The method of claim 16, wherein activating an alert comprises providing a warning to the patient that a reversal agent will be administrated to the patient unless the patient performs a required task that communicates to the system that the patient is alert.

20. The method of claim 16, further comprising automatically administering a second dose of reversal agent to the patient if the patient parameter does not rise above the established threshold after the administration of the first dose.
