Abstract

A drug delivery system includes drug containers, a pump assembly, a sensor, and a controller. The drug containers each contain a different predetermined drug co-formulation of predetermined first and second drugs, wherein the first drug has a sedative effect. The sensor is adapted to sense a variable associated with the drug containers and output a different drug co-formulation identification signal associated with each of the drug containers based on the sensed variable. The controller is programmed to identify the drug co-formulation for the drug container operatively connected to the pump assembly from the associated identification signal and to control the pump assembly to deliver the drug co-formulation of the one drug container to the patient during a medical procedure according to a corresponding drug delivery algorithm which is different for each of the drug containers. A method is also disclosed which uses the drug delivery system.

d) a controller operatively connected to the sensor and to the pump assembly, wherein the controller is programmed to identify the drug co-formulation for the operatively-connected one of the drug containers from the associated identification signal and to control the pump assembly to deliver the drug co-formulation of the operatively-connected one of the drug containers to the patient during the medical procedure according to a corresponding drug delivery algorithm which is different for each of the drug containers.

2. The drug delivery system of claim 1, wherein the second drug has an analgesic effect.

3. The drug delivery system of claim 2, wherein the first drug substantially lacks having an analgesic effect, and wherein the second drug substantially lacks having a sedative effect.

4. The drug delivery system of claim 1, wherein the different predetermined drug co-formulations include at least first, second, third, and fourth drug co-formulations.

5. The drug delivery system of claim 1, wherein the first drug co-formulation includes 100 percent of a predetermined first amount of the first drug and includes 0 percent of a predetermined second amount of the second drug, wherein the second drug co-formulation includes from 60 to 90 percent of the first amount of the first drug and includes from 10 percent to 40 percent of the second amount of the second drug, and wherein the third drug co-formulation includes from 10 percent to 40 percent of the first amount of the first drug and includes from 60 percent to 90 percent of the second amount of the second drug.

6. The drug delivery system of claim 1, wherein the first drug is propofol and the second drug is ketamine.

7. The drug delivery system of claim 1, wherein the first drug is propofol and the second drug is remifentanil.

8. The drug delivery system of claim 1, wherein the drug containers each have substantially a same shape and a different size, wherein the variable is the different size, and wherein the sensor senses the size.

9. The drug delivery system of claim 1, also including a different bar code associated with each of the drug containers, wherein the variable is the different bar code, and wherein the sensor is adapted to automatically sense the bar code associated with the operatively-connected one of the drug containers.

10. The drug delivery system of claim 1, also including a different bar code associated with each of the drug containers, wherein the variable is the different bar code, and wherein the different bar code associated with each of the drug containers is placed on the associated drug container.

11. The drug delivery system of claim 1, also including a different bar code associated with each of the drug containers, wherein the variable is the different bar code, and wherein the different bar code associated with each of the drug containers is placed on at least one of an associated drug-container package and an associated drug-delivery cassette.

12. The drug delivery system of claim 1, wherein the controller is programmed to receive a plurality of physiological parameters of the patient during the medical procedure, and wherein the controller is programmed to have the corresponding drug delivery algorithm adjust a flow rate of the drug co-formulation of the operatively-connected one of the drug containers to the patient during the medical procedure as a function of at least the received physiological parameters.

13. The drug delivery system of claim 12, wherein the controller is programmed to generate at least one alarm signal based at least on the received physiological parameters.

14. The drug delivery system of claim 12, wherein the controller is adapted to receive a user input and to modify the adjusted flow rate of the drug co-formulation of the operatively-connected one of the drug containers to the patient during the medical procedure based on the received user input.
