User authorization system and method for a sedation and analgesia system
First Claim
1. A sedation and analgesia system comprising:
- a patient health monitor device adapted so as to be coupled to a patient and generate a signal reflecting at least one physiological condition of the patient;
a user interface allowing a user to enter inputs;
a drug delivery controller supplying one or more drugs to the patient;
an electronic controller operably connected to the patient health monitor, and the drug delivery controller, wherein said electronic controller receives said signal and in response manages the application of the drugs in accord with stored parameters of at least one monitored patient physiological condition; and
a security system incorporated into said user interface that requires said user to input authorized personal identification information so as to restrict unauthorized use of said sedation and analgesia system, wherein information related to negative procedural events during the use of said sedation and analgesia system is recorded in association with said authorized personal identification information of said user and said information related to negative procedural events is used to determine future authorization of said user, and wherein administrative access to the sedation and analgesia system is separable from access to features of the sedation and analgesia system related to drug delivery and/or patient care.

Abstract
The present invention comprises a security system integral with a sedation and analgesia system. The invention includes a computer assisted IV drug infusion administration device coupled with a secure user interface, or other security means, that can restrict and monitor user access to prevent unauthorized or improper use of the device. The system can also provide varying levels of access to the device so that different users may have different levels of access to system operations. The variety of access levels may prevent accidental or intentional misuse of the drug delivery system, while still permitting access to the required functionality. Data, such as usage statistics and procedural events associated with drug delivery, may be recorded in association with a user'"'"'s personal identification information to help identify training needs and to identify possible misuse of access information.

11. A method of operating a sedation and analgesia system comprising the steps of:
-
connecting to a patient a drug delivery device having a drug delivery controller supplying one or more drugs, said drug delivery controller being coupled to an electronic controller which controls the delivery of the drugs to the patient; attaching at least one patient health monitor device to a patient, which health monitor device generates a value reflecting at least one physiological condition of a patient and is coupled to said electronic controller; inputting into a security system identification information of an authorized user to enable operation of said sedation and analgesia system; accessing a safety data set reflecting parameters of at least one patient physiological condition; delivering the drugs to the patient in accord with the safety data set, and recording information related to negative procedural events during the use of said sedation and analgesia system in association with said security system identification information wherein said information related to negative procedural events is used to determine future authorization of said user, and wherein administrative access to said information is separable from access to features of the sedation and analgesia system related to drug delivery and/or patient care. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
