Abstract:
A system for producing multiple diagnostic test elements, comprising:a) a support with an analytical region for applying diagnostic test spots; b) a first holding unit into which the support can be inserted and positioned; c) a first printing head which is arranged above the first holding unit and which can be used to release fluid drops of a first reagent onto the analytical region of the support; d) a first positioning unit which can laterally displace and position the first holding unit; e) a second holding unit into which the support can be inserted and positioned; f) a second printing head which is arranged above the second holding unit and which can be used to release fluid drops of a second reagent onto the analytical region of the support; g) a second positioning unit which can laterally displace and position the second holding unit; h) a transport unit which can transport the support into the holding units; i) a control unit which controls the transport unit, the holding units and the positioning units and the release of reagent from the printing heads; and j) at least one quality assurance device which can optically examine the fluid drops of the first or second reagent and convert deviations of the fluid drops from a specified pattern into signals which control a lateral adjustment of a relative position of the first printing head with respect to the first holding unit or of a relative position of the second printing head with respect to the second holding unit.
