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.
Claims18
An automated first responder system, the system comprising:
- a patient monitor comprising a hardware processor configured to derive first physiological parameter values from one or more physiological signals obtained from one or more physiological sensors coupled with a patient;
- and
- an autonomous delivery device in communication with the patient monitor, the autonomous delivery device comprising a substance;
- the hardware processor configured to:
- analyze the first physiological parameter values to determine that the first physiological parameter values correspond with a diagnostic model;
- output an alarm based on the determination that the first physiological parameter values correspond with the diagnostic model;
- determine that a response to the alarm has not been received within a predetermined time period;
- cause the substance to be administered to the patient subsequent to the determination that a response to the alarm has not been received within the predetermined time period, and
- subsequent to the substance having been administered to the patient in response to the determination that the first physiological parameter values correspond with the diagnostic model:
- derive second physiological parameter values;
- analyze the second physiological parameter values to determine that the second physiological parameter values also correspond with the diagnostic model;
- and
- responsive to said determination that the second physiological parameter values correspond with the diagnostic model, output a second alarm indicating that an additional amount of the substance may be necessary for the patient, wherein the hardware processor is restricted from automatically causing the autonomous delivery device to administer the additional amount of the substance unless the second physiological parameter values include one or more life-threatening parameter values.
