The control of the temperature within a controller of a biological analysis reducing the thermal variation between the temperatures of the input and output of the air

摘要

The present invention relates to a system for controlling the temperature in an automated biological analysis, the automaton comprising essentially: means for supporting and guiding of the step-by-step displacement of the cups of the reaction on a path comprising a predetermined number of positions, a rotary support plate of the samples to be analyzed, a rotary support plate of the reagents, the sampling means of predetermined quantities of samples and the reagents and of the injection of these samples in the recesses of the reaction, the washing means of the cups, means of optical reading of the results of measurement and a computer system for the execution of cycles of the analysis previously been programmed, it consists in the fact that the system for controlling the temperature is associated with the lower part of the rotary support plate of the samples to be analyzed, said system comprises in its interior: at least one inlet deflector (2) of air, at least one outlet deflector (3) of air, a circular path of transfer of air (4) is positioned between the inlet deflector (2) and the outlet deflector (3), and means for generating the forced air at the level of the circular path (4), which makes it possible to reduce the thermal variation between the inlet and outlet temperatures of the air within the system for controlling the température.l' invention finds a preferred application in the diagnosis.
