Patent ID: 7788108

Claim:
A cross-contamination prevention system relating to an automatic analyzer having a reagent pipetting probe for pipetting a predetermined amount of a reagent into a reaction cuvette and a rinsing mechanism for rinsing said reagent pipetting probe, comprising: a maintenance office device for storing and receiving reagent cross-contamination information of a combination of an offensive reagent and a defensive reagent, with the defensive reagent to be affected by the offensive reagent; an information transmission unit connected to the maintenance office device and a first automatic analyzer via a first communication line, the information transmission unit transmitting reagent cross-contamination information obtained by a test using the first automatic analyzer; and an information receiver unit connected to the maintenance office device and a second automatic analyzer which is installed at the one or more customer's location, through a second communication line, the information receiver unit receiving the reagent cross-contamination information stored at the maintenance office device; wherein the maintenance office device includes a true or false validating unit to validate whether the reagent cross-contamination information transmitted from the information transmission unit is true or false; and wherein the maintenance office device includes a transmitting mechanism to transmit the reagent cross-contamination information stored in the maintenance office device and periodically judged to be true by the true or false validating unit to the information receiver unit; and wherein the maintenance office device transmits cross-contamination data to be managed by an analyzer manufacturer; and wherein the maintenance office charges fees in exchange for the cross-contamination information transmitted.
