1. An autonomous drug delivery system comprising:
- an IV line;
a first automated IV drug delivery system administering a first drug using the IV line; and
a second drug delivery system administering a second drug using the IV line, the second drug being an antagonist drug which is known to counter the effects of the first drug, the second drug delivery system comprising;
a housing having a front panel and a drug compartment;
a display and a plurality of buttons disposed on the front panel;
an IV injector disposed in the drug compartment;
a nozzle extending from the housing in mechanical communication with the IV injector;
a digital signal processor that;
receives, from a patient monitor, an input of at least one physiological parameter measured from a patient,calculates a confidence indicator based upon the at least one physiological parameter,determines that the at least one physiological parameter exceeds a threshold and that the confidence indicator is of a sufficient confidence level, andtriggers an alarm to a caregiver in response to the determination; and
an instrument manager responsive to the determination to automatically initiate delivery of the second drug after a predetermined time interval passes without the alarm being acknowledged.

Abstract
An autonomous drug delivery system advantageously utilizes physiological monitor outputs so as to automatically give a bolus of a rescue drug or other necessary medication when certain criteria and confidence levels are met. An emergency button is provided to manually trigger administration of the rescue drug. The rescue drug may be an opioid antagonist in response to an analgesia overdose, a hypotensive drug to avert an excessive drop in blood pressure or an anti-arrhythmia drug to suppress abnormal heartbeats, to name a few.

7. An IV drug delivery system comprising:
-
a first drug delivery system in fluid communication with an IV line providing fluid to a patient, the first drug delivery system configured to provide a first drug to the patient; a second drug delivery system in fluid communication with the IV line, the second drug delivery system configured to provide a second drug to the patient upon receipt of a trigger signal, the second drug known to counteract an adverse effect of the first drug; a processor that; receives, from a patient monitor, an input of at least one physiological parameter of the patient, calculates a confidence indicator based upon the at least one physiological parameter, determines that the physiological parameter exceeds a threshold and that the confidence indicator meets a confidence level, triggers an alarm in response to the determination that the physiological parameter exceeds the threshold and that the confidence indicator meets the confidence level, after a predetermined time interval passes without the alarm being acknowledged, automatically sends the trigger signal to the second drug delivery system to cause the second drug delivery system to begin administration of the second drug. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17)
