Rail-type full-automatic biochemical analyzer

Abstract

The invention provides a rail-type full-automatic biochemical analyzer with a plurality of reagent needles, which comprises a colorimetric cup, a movable platform for bearing the colorimetric cup, a sample cup rail for placing a sample cup, a sample adding device arranged above the movable platform, a reagent adding device and a colorimetric analysis device. The rail-type full-automatic biochemical analyzer with a plurality of reagent needles is characterized in that the rectangular movable platform is arranged on the rail, the motion direction of the sample cup rail is parallel to that of the movable platform, the reagent adding device comprises more than two reagent bottles, more than two precise reagent pumps and reagent needles, and the reagent needles comprise more than two reagent needle units. A circumferential motion mode is changed into a linear motion mode so that reagent addition, sample addition and colorimetric analysis are more convenient to control and the control precision is more convenient to keep. The working efficiency of the analyzer is improved by arranging more than two reagent needle units on the reagent needles.

Description

technical field [0001] The present invention relates to a track-type automatic biochemical analyzer, and more specifically relates to a track-type full-automatic biochemical analyzer which can be provided with multiple reagent needles. Background technique [0002] The automatic biochemical analyzer is mainly used for rapid quantitative analysis of biochemical and chemical components in clinical blood and body fluid samples. It is a routine inspection instrument in modern hospitals. Now most discrete biochemical analyzers can only add one reagent and Samples, and the number of cuvettes and sample bottles is small, which makes the work efficiency of the existing biochemical analyzers very low, and cannot meet the needs of large hospitals. In the existing automatic biochemical analyzer, the reaction chamber used to carry the cuvette is a circular structure, and the reaction chamber rotates at an angle, and the reagent can only be filled once through the reagent needle, and the...

AI Technical Summary

Problems solved by technology

The reagent needle on the existing automatic biochemical analyzer is in the form of a single reagent needle, which can only fill one cuvette unit with reagent at a time, and the reagent filling is slow, which makes the work efficiency of the analyzer low

In addition, the cuvettes on the existing biochemical analyzers are recyclable. When they are reusable, cross-contamination is easily caused due to unclean cleaning, and the cuvettes will be worn to a certain extent during long-term use. It makes its light transmittance poor, cross-contamination and wear can lead to a large difference between the measured experimental data and the actual data
