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 for providing sedation and/or pain relief without general anesthesia to patients undergoing a medical and/or surgical procedure, said system comprising:

a plurality of patient health monitors adapted to be coupled to a plurality of patients undergoing a medical or surgical procedure, said patient health monitors generating a signal reflecting measurements of at least one monitored physiological condition of the patients;

at least one electronic controller having safe and/or effective parameters for said monitored physiological condition, said parameters indicating values for said measurements of said monitored physiological condition patient where said values correlate to safe and/or effective sedation during said procedure, and said electronic controller being adapted to receive said signal, compare said measurements reflected in said received signal with said parameters, and provide an alarm in the event said signal is outside of said safe and/or effective parameters; and

a remote monitor and control system for receiving data from the sedation and analgesia system including said signal, and/or alarm and for displaying said signal in a display, pertaining to each patient and wherein an authorized user can modify, control and/or override the electronic controller through the remote monitor and control system.

2. The sedation and analgesia system according to claim 1, wherein the authorized user is an anesthetist and/or anesthesiologist.

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

4. The sedation and analgesia system according to claim 1, wherein the data received by the remote monitor and control system comprises one or more of the signals 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. The sedation and analgesia system according to claim 1, wherein said display further comprises video transmissions of said procedure in addition to that of receiving sedation and/or analgesia being performed on said patient.

6. The sedation and analgesia system according to claim 1, wherein said remote monitor and control system receives data from a plurality sedation and analgesia systems.

7. A sedation and analgesia system for providing sedation and/or pain relief to a plurality of patients during a medical and/or surgical procedure, said system comprising:

a patient health monitor adapted to be coupled to each patient to generate a signal reflecting at least one physiological condition of the patient;

a drug delivery controller supplying one or more sedative and/or analgesic drugs to each patient;

a device that stores safe parameters of at least one monitored patient physiological condition for each patient;

a remote interface to the patient health monitors, the drug delivery controllers and the devices that stores the parameters, wherein said remote interface receives said signal and displays said signal with other patient data that is relevant to a safe physiological condition of each patient, and enables an authorized clinician to control or override said drug delivery controllers through said remote interface to insure that said sedative and/or analgesic drugs are supplied to said patients in a safe and effective manner.

8. The sedation and analgesia system according to claim 7, wherein the device that stores the parameters is remote from the patient health monitors and the drug delivery controllers.

9. The sedation and analgesia system according to claim 7, wherein the drug delivery controllers generates a signal reflecting the dose of drug delivered to a patient and wherein the parameters indicate one or more safe patient conditions, wherein the remote interface receives said signal reflecting the dose of drug delivered and in response modifies a supply rate of the drugs in accord with the parameters.

10. The sedation and analgesia system according to claim 9, wherein the remote interface displays drug delivery data simultaneously with video transmissions relevant to said separate procedure.

11. The sedation and analgesia system according to claim 7, further comprising a system state monitor for generating a signal reflecting a change in condition of the sedation and analgesia system, wherein the remote interface receives said signal reflecting said change in the sedation and analgesia system and in response manages the application of the drugs in accord with the change.

12. The sedation and analgesia system according to claim 11, wherein the remote interface locks down the sedation and analgesia system upon receipt of said signal reflecting said change in the sedation and analgesia system.
