System for verifying accuracy of serially-connected drug modules in a combinatorial drug delivery device
In one aspect, a system is provided of verifying the accuracy of a plurality of serially-connected drug modules of a combinatorial drug delivery device, each of the drug modules including a drug reservoir, the system including: a machine-readable code located on each of the drug modules; application software configured to generate an activation code based on the machine-readable codes and the sequence of the machine-readable codes; a flow controller on the drug delivery device which is selectively actuatable to a use state to permit flow of drug from the drug delivery device; and, a control unit on the drug delivery device having a computing processing unit configured to compare the activation code with an authentication code, and, wherein, if the authentication code matches the activation code, the computing processing unit causes actuation of the flow controller to permit flow of the drug from the drug delivery device.
1. A method of preparing a combinatorial drug delivery device for a patient, the method comprising:
preparing a plurality of serially-connectable drug modules, each containing a drug component or diluent, for the patient;
affixing a machine-readable code to each of the plurality of drug modules, wherein the machine-readable codes each represent an alphanumeric data string associated with the drug component or diluent contained in the corresponding drug module; and,
associating an authentication code with the plurality of drug modules, wherein the authentication code is based on a combination of the alphanumeric data strings assembled together in a pre-defined sequence of the plurality of drug modules being serially connected.
2. The method of claim 1 , further comprising: providing a flow controller.
3. The method of claim 2 , further comprising: providing a control unit having a computing processing unit configured to actuate the flow controller.
4. The method of claim 3 , further comprising storing the authentication code on a non-transitory memory associated with the computing processing unit.
5. The method of claim 4 , wherein the computing processing unit is configured to actuate the flow controller based on a match between the authentication code and an activation code received by the computing processing unit.
6. The method of claim 3 , wherein the computing processing unit is configured to actuate the flow controller based on an approval message received by the computing processing unit, the approval message being generated remotely from the computing processing unit based on the authentication code.
7. The method of claim 3 , wherein the flow controller and the control unit are contained in a controller housing.
8. The method of claim 7 , further comprising: delivering the plurality of drug modules and the controller housing to a point of assembly.
9. The method of claim 1 , wherein the machine-readable codes are selected from one or more of the group consisting of: QR codes and bar codes.
10. The method of claim 1 , wherein each of the machine-readable codes represents a type of the drug component or diluent contained in the corresponding drug module.
11. The method of claim 10 , wherein each of the machine-readable codes represents a concentration of the drug component contained in the corresponding drug module.
12. The method of claim 1 , wherein the plurality of drug modules is prepared for the patient based on a prescription for the patient.
13. A method of preparing a combinatorial drug delivery device for a patient, the method comprising:
preparing a plurality of drug modules, each containing a drug component or diluent, for the patient;
affixing a machine-readable code to each of the plurality of drug modules, wherein the machine-readable codes each represent an alphanumeric data string associated with the drug component or diluent contained in the corresponding drug module;
associating an authentication code with the plurality of drug modules, wherein the authentication code is based on a combination of the alphanumeric data strings assembled together in a sequence of the plurality of drug modules pre-defined for the patient;
providing a flow controller;
providing a control unit having a computing processing unit configured to actuate the flow controller; and,
storing the authentication code on a non-transitory memory associated with the computing processing unit,
wherein the computing processing unit is configured to actuate the flow controller based on a match between the authentication code and an activation code received by the computing processing unit.
14. The method of claim 13 , wherein the flow controller and the control unit are contained in a controller housing.
15. The method of claim 14 , further comprising: delivering the plurality of drug modules and the controller housing to a point of assembly.
16. The method of claim 13 , wherein the machine-readable codes are selected from one or more of the group consisting of: QR codes and bar codes.
17. The method of claim 13 , wherein each of the machine-readable codes represents a type of the drug component or diluent contained in the corresponding drug module.
18. The method of claim 13 , wherein each of the machine-readable codes represents a concentration of the drug component contained in the corresponding drug module.
