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.

First claim

What is claimed is:

1. A system, comprising:
(a) a computer system comprising:
a computer system memory comprising a medical order for a patient; and
a processor configured to:
retrieve the medical order from the computer system memory; and
store in a medical transaction carrier (MTC) memory of a MTC a new-order message comprising the medical order;

(b) the MTC, comprising:
a rewritable non-volatile MTC memory configured to store:
the new-order message; and
medical transaction data for a patient specific asset (PSA) comprising an infusion pump; and

a processor configured to instruct the MTC to wirelessly communicate with the computer system and the PSA; and

(c) the PSA, comprising:
a PSA memory that is physically separate from the MTC memory, and is distinct from the computer system; and
a processor configured to:
extract the new-order message from the MTC memory;
operate the infusion pump to deliver the medication according to the medical order of the new-order message;
store in the PSA memory a record that the medication has been delivered;
store in the MTC memory an order-complete message indicative that the medication has been delivered;

wherein the processor of the computer system is further configured to:
wirelessly receive the medical transaction data for the PSA stored in the MTC memory;
determine whether the medical transaction data for the PSA is currently pending;
when the medical transaction data for the PSA is determined to be currently pending, mark the medical transaction data for the PSA as cleared; and
wirelessly receive and validate the order-complete message stored in the MTC memory when the order-complete message is received and stored in the computer system memory.

2. The system of claim 1 , wherein:
the computer system memory comprises an order number uniquely associated with the medical order;
the new-order message comprises a unique order identifier;
the order-complete message comprises the unique order identifier; and
wherein validating the order-complete message comprises validating the order-complete message if the unique order identifier of the order-complete message matches the order number in the computer system memory.

3. The system of claim 1 , wherein the computer system is further configured to update the medical record in the computer system memory to indicate that the medicine has been delivered by the PSA if the order-complete message is validated.

4. The system of claim 1 , wherein the MTC is one of the set of a personal data assistant, laptop computer, notebook computer, smart card, magnetic strip card, PCMCIA card, RF-ID.

5. The system of claim 1 , wherein the MTC is primarily stationary and located at the bedside of the patient.
