System for sterilizing medicinal products by beta-radiation processing
First Claim
1. Method for the sterilization of medical products by irradiation, comprising the steps of:
- placing at least one product provided with a product identification code onto a tray provided with a tray identification code;
reading the tray identification code and the product identification code;
storing the combination of the tray and product identification codes;
conveying the tray along a definite path towards an irradiation station;
sterilizing said at least one product at the irradiation station; and
locating the tray by reading the tray identification code at definite places along the path.

Abstract
A system is provided for sterilizing, by irradiation, a plurality of products, each product having an identification code. The products are carried on product carriers which include a carrier identification code. The system includes a product loading station, a product unloading station, an irradiation blocking containment, and an irradiation station location located within the containment. A conveyor passes from the loading station through the containment to the unloading station. Code readers are located along the conveyor for detecting and reading both the product identification code and the carrier identification code. A control and monitoring circuit receives the codes, and stores in memory an association between specific carriers and the products located on those carriers.

comparing the read product identification code with the identification code of the product previously stored, and, if the products are not of the same type;
blocking the travel of the tray on which the product is placed;
placing a device for measuring the irradiation dose generated by the irradiation station onto a second tray;
setting the irradiation station so that it emits radiation suitable for sterilizing the product;
conveying the tray towards the irradiation station;
measuring the radiation dose received in the irradiation station by means of the measuring device; and
monitoring the measured radiation when the second tray has emerged from the irradiation station.

3. Installation for the sterilization by irradiation of a plurality of medical products, each product having an identification code affixed thereto, the installation comprising:
-
at least one product loading station;
at least one product unloading station;
an irradiation station located inside a containment having walls capable of stopping sterilizing radiation;
conveyance means for conveying the products to be sterilized from the loading station to the irradiation station and the sterilized products from the irradiation station to the unloading station;
a plurality of trays for supporting the products on the conveyance means, each tray being provided with an identification code;
code-reading means, arranged along the conveyance means, for reading the code affixed to each tray and the code affixed to each product; and
control and monitoring means connected to the code-reading means for combining and storing the identification code of each product and the identification code of the tray supporting each product, and for following the travel of the products on the conveyance means. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14)

16. A system for sterilizing, by irradiation, a plurality of products, each product having an identification code thereon, and being carried through the system on a carrier, each carrier having an identification code thereon, the system comprising:
-
at least one product loading station;
at least one product unloading station;
a containment having walls for blocking sterilizing radiation;
an irradiation station located within the containment;
at least one conveyor defining a travel path between the product loading station, the irradiation station and the product unloading station;
at least one carrier code reader arranged along the conveyor, the carrier code reader being configured to detect and read carrier identification codes and for outputting carrier code data;
at least one product code reader arranged along the conveyor and being configured to detect and read product identification codes and for outputting product code data; and
a control and monitoring circuit for receiving carrier code data and product code data, for storing in memory an association between specific carriers and product located thereon, and for monitoring travel of the products along said at least one conveyor using carrier code data. - View Dependent Claims (17)
