Abstract

The present invention concerns a method and a system for tracking medical products in which the product (11, 12) and/or its packaging (16) is marked and identified with a first reference (18) that is stored in a first file (20) and the packaged product is shipped (7) to the client for storage for subsequent use for a patient listed in a second file (31). The references of the product are detected (27) automatically and remotely when it is shipped and stored in a third, or stock control, file (28) of the client at the time of an operation. Removal of the product from stock is detected (30) automatically, the references of the product are inserted in the second file (31) corresponding to the patient of the client for which it is used or is to be used, a fourth file is constructed (36) comprising partial references coming from the file of the patient and the references of the product that have been determined for tracking purposes, and this fourth file is transmitted (52) automatically or semi-automatically to the supplier (4) of the product.

Claims

1. A method of tracking medical products in which a marked packaged medical product is identified by a supplier of said product by a first reference stored in a first product file, the medical product being stored at a client facility for subsequent use for a patient identified in a second patient file, the method comprising the steps of:

detecting the first reference of the medical product automatically and storing said first reference in a third client file,

detecting removal of the product from stock automatically,

inserting the first reference of the removed medical product in the second patient file corresponding to a patient for which the medical product is used or to be used,

constructing a fourth file comprising partial references coming from the second patient file, said fourth file comprising the first reference of the medical product and expurgated patient data which includes a patient identifier but protects the medical confidentiality of the patient, and

transmitting the fourth file automatically or semi-automatically to the supplier of the product.

6. The method according to claim 1, wherein the medical product is a surgical implant.

7. The method according to claim 1, wherein the medical product is a medication.

8. The method according to claim 1, further comprising:

automatically detecting a simultaneous or substantially simultaneous removal from stock of at least two medical products and automatically inserting references of the two medical products used for the patient in the second patient file and then removing medical products re-entered into stock after operation on the patient.

9. The method according to claim 1, wherein the marked packaged medical product has removable packaging that is configured to be marked and detected by optical recognition means.

10. The method according to claim 1, wherein the marked packaged medical product has removable packaging that is configured to be marked and detected by radio-frequency recognition means.

11. The method according to claim 1, wherein said marked packaged medical product comprises removable packaging and a detachable card attached to an RFID microchip contained in said packaging, wherein said RFID microchip is loaded with information on said medical product contained in said packaging, information on the patient, date and type of operation carried out are stored in said RFID microchip, and further comprising the step of using said card for storing additional information on post operative action.

12. The method according to claim 11, wherein said RFID microchip has an individual serial number enabling automatic recovery of all the data for any previous operation, either directly by reading a file contained in the microchip or by automatic calling up of the patient file.
