Abstract

The present invention comprises a sedation and analgesia system having integrated patient monitoring and drug delivery, where information related to monitored patient parameters and drug delivery is accessible and controllable from a remote location. Information relative to monitored patient parameters and drug delivery may be provided in real-time or near real-time, to an attending nurse, physician, insurance company, billing department, or other suitable party according to the present invention via a computing device, video monitor, over the Internet, over an intranet, or by any other suitable means of transmitting and displaying critical data. The present invention further comprises an integrated in-room monitor, where data related to critical patient parameters and drug delivery may be integrated with other means of communicating data related to a patient, a procedure, or a medical device.

Claims

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 drug delivery controller supplying one or more drugs to the patient;

a memory device storing a safety data set reflecting safe and undesirable parameters of at least one monitored patient physiological condition;

an electronic controller interconnected between the patient health monitor, the drug delivery controller and the memory device storing the safety data set;

wherein said electronic controller receives said signal and in response manages the application of the drugs in accord with the safety data set; and

a monitor, wherein the monitor is remote from the sedation and analgesia system and wherein the remote monitor receives data from the sedation and analgesia system.

2. The sedation and analgesia system according to claim 1, wherein the monitor receives data from the sedation and analgesia system in real time as the sedation and analgesia system operates.

3. The sedation and analgesia system according to claim 1, further comprising a remote memory device, wherein the monitor and the remote memory device are interconnected such that the monitor stores the data from the sedation and analgesia system in the remote memory device.

4. The sedation and analgesia system according to claim 1, wherein the data received by the monitor comprises one or more of the signal reflecting at least one physiological condition of the patient, a dose of drug supplied by the drug delivery controller, and information regarding maintenance performed on the sedation and analgesia system.

5. 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 drug delivery controller supplying one or more drugs to the patient;

a memory device storing a safety data set reflecting safe and undesirable parameters of at least one monitored patient physiological condition;

a remote interface to an electronic controller, the electronic controller being in communication with the patient health monitor, the drug delivery controller and the memory device storing the safety data set;

wherein said electronic controller receives said signal and in response manages the application of the drugs in accord with the safety data set.

6. The sedation and analgesia system according to claim 5, wherein the memory device is remote from the patient health monitor and the drug delivery controller.

7. The sedation and analgesia system according to claim 5, wherein the drug delivery controller generates a signal reflecting the dose of drug delivered to a patient and wherein the safety data set reflects undesirable parameters for drug dosage, wherein the electronic controller receives said signal reflecting the dose of drug delivered and in response manages the application of the drugs in accord with the safety data set.

8. The sedation and analgesia system according to claim 7, wherein the electronic controller locks down the sedation and analgesia system if the signal reflecting the dose of drug delivered to the patient reflects the undesirable parameters for drug dosage in the safety data set.

9. The sedation and analgesia system according to claim 5, further comprising a system state monitor for generating a signal reflecting a malfunction of the sedation and analgesia system, wherein the electronic controller receives said signal reflecting a malfunction of the sedation and analgesia system and in response manages the application of the drugs in accord with the malfunction.

10. The sedation and analgesia system according to claim 9, wherein the electronic controller locks down the sedation and analgesia system upon receipt of said signal reflecting a malfunction of the sedation and analgesia system.

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;

accessing a memory device which stores a safety data set reflecting parameters of at least one patient physiological condition;

monitoring data remotely from the drug delivery device, the data being from the sedation and analgesia system; and

delivering the drugs to the patient in accord with the safety data set.

12. The method of operating a sedation and analgesia system according to claim 11, wherein the step of remotely monitoring data comprises remotely monitoring the value reflecting at least one physiological condition of a patient, a dose of drug supplied by the drug delivery device, and information regarding maintenance performed on the sedation and analgesia system.

13. The method of operating a sedation and analgesia system according to claim 12, wherein the safety data set further reflects parameters of one or more of the dose of drug supplied by the drug delivery device, and information regarding maintenance performed on the sedation and analgesia system.

14. The method of operating a sedation and analgesia system according to claim 11, wherein the step of delivering the drugs to the patient in accord with the safety data set comprises locking down the sedation and analgesia system.

15. The method of operating a sedation and analgesia system according to claim 11, wherein the step of accessing a memory device is performed remotely from the drug delivery device.

16. The method of operating a sedation and analgesia system according to claim 11, wherein the step of remotely monitoring data comprises remotely monitoring the dose of drug delivered to a patient and wherein the safety data set reflects undesirable parameters for drug dosage, wherein the electronic controller receives said signal reflecting the dose of drug delivered and in response manages the application of the drugs in accord with the safety data set.

17. The method of operating a sedation and analgesia system according to claim 11, further comprising the step of updating billing information based on the data monitored remotely.
