Embodiment Construction

[0029] specific implementation plan

[0030]In order to achieve a "clinician knows best" mode and keep the clinician user in charge while the computer performs repetitive and labor-intensive tasks, the present invention applies computer-assisted drug delivery rather than computer-controlled drug delivery. If automated actions (e.g. drug level reduction) would generally have a safe effect, the computer-assisted drug delivery systems and methods of the present invention can be based on clinical heuristics, initiating well-defined actions without clinician input. The behavior of a predetermined program. The behavior of a predetermined program based on clinical heuristics can be performed in a well-defined finite-state algorithm, where well-defined events such as certain warnings or alarms (based on the patient's physiological response or based on the condition of the drug delivery device), user input, or An acute loss of responsiveness to a stimulus) causes the system to transit...

Abstract

The present invention describes methods and devices for reducing the workload of instilling medication and allowing the clinician-user to control the associated procedure. The drug delivery device 122 is controlled to achieve a target drug concentration or a predetermined infusion rate waveform at a selected site of the patient. The time profile of the target drug concentration or predetermined infusion rate waveform is controlled by a drug state model (38) using clinical heuristics to achieve safe, predetermined changes in target drug concentration or infusion rate and target drug concentration or infusion rate. User-controlled change of note speed. The present invention allows time to assess a patient's response to changes in drug levels by making small increments and steady changes in drug levels over time.

Description

[0001] This application claims priority under 35 U.S.C. §119(e) to US Patent Application Serial No. 60 / 308,591, filed July 31, 2001, which is incorporated herein by reference. technical field [0002] The present invention relates to devices and methods for altering the rate, schedule, and / or effect site concentration of drug delivery to a patient in response to certain events. In particular, the present invention responds to one or more electronic monitoring signals of the patient's physiological condition and / or user observations and inputs through robust and safety-biased software forming part of the drug state model, The infusion of one or more medications (which may be sedatives, pain relievers, or amnestics, for example) is electronically integrated. Background technique [0003] Clinicians typically use drips to achieve the desired effect. In general, differences in patient response to instilled drugs are to be expected since the same amount of drug may have very dif...
