Problems solved by technology

[0004] When the eluting needles are of different lengths, only one anti-collision photoelectric sensor cannot fully reflect the contact situation between all the elution needles and the bottom of the cup, especially when the anti-collision photoelectric sensor is installed in the last elution unit, until the sensor sends out When the alarm occurs, the previous eluting needle may have been bent

Abstract

The invention discloses an anti-collision cleaning mechanism for a reaction cup. The anti-collision cleaning mechanism comprises an elution arm and an elution unit vertically arranged on the elution arm, wherein the elution arm is provided with an anti-collision sensor. The elution unit comprises a pin fixing base, a pin guide base and an elution pin. The elution arm comprises a floating plate and a fixed plate which are overlaid up and down, buffering anticollision mechanisms are arranged between the floating plate and the fixed plate and between the floating plate and the pin fixing base, the anti-collision sensor is arranged on the fixed plate, and the floating plate is provided with a trigger piece for triggering the anti-collision sensor. According to the anti-collision cleaning mechanism, under the protection of the buffering anticollision mechanisms, the phenomena that the elution pin is subjected to collision and damage can be effectively avoided.

Description

technical field [0001] The invention relates to the technical fields of chemiluminescent immunoassay and biochemical analysis, in particular to an anti-collision cleaning mechanism for cuvettes. Background technique [0002] The automatic chemiluminescence immunoassay system is an instrument for immunological quantitative analysis of patient body fluid samples. It can test many diseases and diseases. The advantages of full automation can greatly improve the efficiency of immune analysis, so it is widely used in the fields of modern clinical immunoassay diagnosis and life science research. The system mainly performs a series of immune reactions between the antigen or antibody and the analyte, after washing, and then uses optical instruments to measure the strength of the luminescent signal after the immune reaction of the analyte to indicate the test result. It includes multiple subsystems, among which the cuvette cleaning mechanism is mainly used to clean the excess reagent...
