Abstract

The invention relates to the technical field of microplate sample injection equipment, in particular to a microplate sample injection indicating system. The microplate sample injection indicating system comprises a base, wherein a plurality of indicator lamps are arranged on the upper surface of the base at equal intervals; a placement box is arranged above the base; a plurality of placement grooves are formed in the placement box at equal intervals; a placement plate is arranged at the rear side of the base; a gun groove is formed in the upper surface of the placement plate; and a sample injection gun is embedded inside the gun groove. According to the microplate sample injection indicating system, a sensing module is used for collecting a pressure signal and a palm signal, a key module is used for switching signal data counting and working modes, and a control module is used for analyzing and treating the collected signal data, so that the reduction of error rates of sample injectionis facilitated, and the efficiency of experiment is improved; a display module is used for displaying the analyzed and processed signal data; and a power module is used for supplying power to a circuit, so that the normal operation of the circuit is ensured.

Description

technical field [0001] The invention relates to the technical field of microhole plate sample loading equipment, in particular to a microhole plate sample loading indicator system. Background technique [0002] In laboratories such as biochemistry or sanitation and epidemic prevention inspection, it is often necessary to use microplates for detection tests, and then use a microplate reader to detect the absorbance of each well. The transparent plastic plate of the sample has multiple rows of small holes of uniform size, usually with 40 holes, 48 ​​holes, 55 holes or 96 holes of different specifications, and each hole can hold a small amount of solution. The wells are closely arranged, and there are no obvious marks between adjacent wells. Therefore, it is often easy to add wrong wells during manual sample addition or large-scale sample addition, especially when there is no color change in the reagents in the wells. Greatly increased, reducing the test efficiency, in view of...
