Abstract

A system and method for communicating and validating patient information including medication delivery information in a care-giving facility is provided. A medical transaction carrier is used to communicate information regarding medication delivery and other patient information between a control system in communication with the care-giving facility'"'"'s other information systems and a patient specific asset such as an infusion pump. All information carried by the medical transaction carrier is validated both at the patient specific asset and at the control system. This validation allows for positive control of all transactions even if a medical transaction carrier is lost. The medical transaction carrier may be a smartcard, a PDA such as a Palm™ Pilot, laptop computer, pager, mobile phone, or other device capable of storing and communicating information. The system may use either wired or wireless connections to communicate information between the components of the system.

Claims

1. A system for managing information relating to the delivery of medication to a patient, comprising

a medication order data base in which medication orders for patients are stored and each order is assigned a unique identifier;

a computer in communication with the medication order data base and adapted to process the medication orders stored in the database;

a medical transaction carrier having;

a memory for storing medication order information including medication orders;

a patient specific asset configured for physically interacting with a patient, and having;

a communication device to communicate with the medical transaction carrier;

a memory adapted to store medication order information received from the medical transaction carrier; and

a processor adapted to;

compare medication order information stored in the memory of the patient specific asset to medication order information retrieved from the medical transaction carrier to validate the retrieved medical order information;

to communicate through the communication device to the medical transaction carrier that the medication order was received by the patient specific asset;

to continue to communicate to each medical transaction carrier that a medication order resides in the memory until the medical transaction carrier includes a cleared indicator from the computer; and

wherein the computer is configured to compare medication order information stored in the operably connected memory to medication order information communicated from the medical transaction carrier to validate the communicated medication order information;

wherein the medical transaction carrier is configured to establish a first communication link, send a query to, and receive a response from the patient specific asset when the medical transaction carrier is within a first predetermined distance of the patient specific asset and the medical transaction carrier is configured to establish a second communication link with the computer when the medical transaction carrier is within a second predetermined distance of the computer;

wherein the patient specific asset is configured to create a plurality of unique transaction IDs; and

wherein the patient specific asset is configured to create a new log of transactions if no current log of past transactions is pending for clearance and to mark for deletion any past transactions pending for clearance.

2. The system of claim 1, wherein the medical transaction carrier further comprises input/output means for receiving information from an information source to be stored in the memory and for transmitting information stored in the memory to an information receiver.

3. The system of claim 2, wherein the input/output means of the medical transaction carrier and the communication device of the patient specific asset each include a wireless transmitter/receiver.

4. The system of claim 3 wherein the wireless transmitter/receivers are configured to transmit and receive signals using electromagnetic energy.

5. The system of claim 4 wherein the electromagnetic energy is infrared energy.

6. The system of claim 4 wherein the electromagnetic energy is radio frequency energy.

7. The system of claim 2, wherein the input/output means of the medical transaction carrier and the communication device of the computer each include a wireless transmitter/receiver.

8. The system of claim 7 wherein the wireless transmitter/receivers are configured to transmit and receive signals using electromagnetic energy.

9. The system of claim 8 wherein the electromagnetic energy is infrared energy.

10. The system of claim 8 wherein the electromagnetic energy is radio frequency energy.

11. The system of claim 1 wherein the communication device of the patient specific asset includes a reader configured to provide a communication path between the medical transaction carrier and the patient specific asset.

12. The system of claim 11 wherein the patient specific asset includes a housing and the reader is mounted within the housing.

13. The system of claim 11 wherein the memory of the medical transaction carrier is a magnetic strip and the reader is a magnetic strip reader.

14. The system of claim 11 wherein the medical transaction carrier is a smart card and the reader is configured to provide a communication path between a smart card and the patient specific asset.

15. The system of claim 11 wherein the medical transaction carrier includes an embedded processor and the reader is configured to provide a communication path between the embedded processor and the patient specific asset.

16. The system of claim 11 wherein the medical transaction carrier is a PDA and the reader comprises a cradle configured to provide a communication path between the PDA and the patient specific asset.

17. The system of claim 1, wherein the medical transaction carrier is a smart card.

18. The system of claim 1 wherein the medical transaction carrier is a personal data assistant (PDA).

19. The system of claim 18 wherein the PDA includes a means for manually entering information into the memory of the PDA.

20. The system of claim 1 wherein the medical transaction carrier includes an embedded processor.

21. The system of claim 1 wherein the patient specific asset is an infusion pump.

22. The system of claim 1 wherein the medication order information includes information identifying the location of the patient specific asset in an facility.

23. The system of claim 1 wherein the medication order information includes an identification of a care-giver delivering medication to a patient.
