Abstract

A system for safe delivery of drug to a patient employs a programmable memory card for transferring drug delivery instructions and patient information between a server in a pharmacy and a drug delivery apparatus in a patient room. The server in the pharmacy checks the prescription for safety and the drug delivery apparatus checks for the drug delivery instructions and also the patient identity. The drug delivery apparatus records the information about the drug delivered to the patient onto the programmable memory card at the end of the drug delivery.

Claims

1. A method, for safe drug delivery, comprising the steps of:

retrieving wirelessly, from a programmable memory card, a patient identity, forming a retrieved patient identity;

comparing, at a drug delivery device, the retrieved patient identity with a stored patient identity in the drug delivery device;

issuing an alert if the stored patient identity is different from the retrieved patient identity; and

recording wirelessly, by the drug delivery device, drug delivery data in the programmable memory card,

wherein

the drug delivery device is not connected to a network, and

the drug delivery data comprises type of drug, amount of drug delivered, drug delivery rate, and time of drug delivered.

2. The method of claim 1, further comprising the steps of:

retrieving, from the programmable memory card, a plurality of drug delivery parameters, forming the retrieved drug delivery parameters;

receiving, at the drug delivery device, a drug delivery parameter, forming a received drug delivery parameter; and

overriding at least one retrieved drug delivery parameter with the received drug delivery parameter.

3. The method of claim 2, further comprising the step of overriding default operational options in the drug delivery device with options in the retrieved drug delivery parameters.

4. The method of claim 2, further comprising the steps of:

checking the received drug delivery parameter against a set of safe limits; and

issuing an alert if the received drug delivery parameter is outside of the set of safe limits.

5. The method of claim 1, further comprising the step of:

if the retried patient identity is different from the stored patient identity, updating the stored patient identity with the retrieved patient identity; and

enabling the drug delivery device to be used for a patient identified by the retrieved patient identity.

6. The method of claim 1, further comprising the steps of:

retrieving, from the programmable memory card, drug delivery parameters; and

delivering, by the drug delivery device, drug according to the drug delivery parameters.

7. The method of claim 6, further comprising the steps of:

checking default operational options of the drug delivery device against the drug delivery parameters to determine if the drug delivery device is functionally capable of delivering the drug; and

issuing an alert if the drug delivery device is functionality incapable of delivering according to the drug delivery parameters.

8. The method of claim 1, further comprising the steps of:

interrupting drug delivery by the drug delivery device; and

resuming the drug delivery if the retrieved patient identity matches with the stored patient identity.

9. A method, for interfacing with a programmable memory card, comprising the steps of:

checking received prescription information against information stored in a drug library on a server;

issuing an alarm if the received prescription information is outside the range defined in the drug library; and

storing, by a card interface, drug delivery instructions and patient identity retrieved from the server in a programmable memory card.

10. The method of claim 9, further comprising the steps of:

retrieving drug delivery data from the programmable memory card;

comparing the drug delivery data with patient data on the server; and

issuing an alert if the drug delivery data is different from patient data,

wherein the drug delivery data comprises type of drug, amount of drug delivered, drug delivery rate, and time of drug delivered.

11. The method of claim 9, wherein the step of checking received prescription information against information stored in a drug library further comprises the step of comparing a prescribed drug dose against a drug dose limit in the drug library.

12. The method of claim 11, further comprising the step of overriding the prescribed drug dose with a drug dose received by the server.

13. A safe drug delivery apparatus comprising:

a memory card interface for retrieving drug delivery instructions from a memory card and for storing drug delivery data onto the memory card;

a non-transitory computer readable storage unit for storing the drug delivery instructions and drug delivery parameters derived from the drug delivery instructions;

a controller for checking a patient identity in the non-transitory computer readable storage unit against a patient identity in the drug delivery instructions; and

a drug delivery mechanism for delivering drug to a patient according to the drug delivery parameters,

wherein

the drug delivery data comprises type of drug, amount of drug delivered by the drug delivery mechanism, drug delivery rate, and time of drug delivered, and

the safe drug delivery apparatus is not connected to a network.

14. The safe drug delivery apparatus of claim 13, further comprising a user interface for receiving a drug delivery dose from a user, wherein the controller overrides a prescribed drug delivery dose in the drug delivery instructions with the drug delivery dose received through the user interface.

15. The safe drug delivery apparatus of claim 13, wherein the controller overrides the patient identity in the non-transitory computer readable storage unit with the patient identity in the drug delivery instructions.

16. The safe drug delivery apparatus of claim 13, wherein the controller issues an alert if the patient identity in the non-transitory computer readable storage unit is different from the patient identity in the drug delivery instructions.

17. The safe drug delivery apparatus of claim 13, wherein the memory card interface is a radio frequency identification card reader and writer.

18. The safe drug delivery apparatus of claim 13, wherein the memory card interface is a magnetic card reader and writer.

19. The safe drug delivery apparatus of claim 13, wherein the controller can interrupt drug delivery by the drug delivery mechanism and stores drug delivery data onto the memory card.

20. The safe drug delivery apparatus of claim 13, wherein the controller checks the patient identity retrieved from the memory card against the patient identity stored in the non-transitory computer readable storage unit before resuming drug delivery.
