Problems solved by technology

[0008] The purpose of the present invention is to adjust the height positioning of the reagent arm of the instrument through visual observation in the prior art, resulting in large positioning error and low accuracy of the reagent arm height of each instrument, which directly causes the reagent arm of the instrument to be debugged Inaccurately affecting the addition of the reagent arm to the reagent cuvette, the reagent capacity is inaccurate, and the operation is troublesome and the efficiency is low. A method for adjusting the position of the reagent arm is provided.

Abstract

The invention relates to the technical field of in vitro diagnosis, in particular to a method for adjusting the position of a reagent arm: making a conductive tooling reaction cup whose inner cavity height is equal to the height of the reagent reaction cup minus the liquid level in the reagent reaction cup which needs to be adjusted for quantitative reagents or samples added The value of the height; the wire is electrically connected to the reagent arm part, the frame support part, the signal prompter and the power supply; the tooling reaction cup is installed on the frame support part; the reagent needle or the sample needle is moved so that it contacts the tooling reaction cup cup At the bottom, the wire conducts electricity, and the height value of the reagent needle or sample needle is recorded, which is the height value of the reagent arm component corresponding to the quantitative reagent or sample volume that needs to be adjusted. The reagent arm position debugging method can achieve the unity of the debugging height and method. The debugging method is simple to operate, convenient to judge, high in adjustment accuracy, reduces the interference of human judgment factors, improves the adjustment efficiency of the height of the reagent arm, and saves debugging time. .

Description

technical field [0001] The invention relates to the technical field of in vitro diagnosis, in particular to a method for adjusting the position of a reagent arm. Background technique [0002] In the process of in vitro diagnostic technology in the field of biomedicine, it will involve the quantitative height adjustment and positioning of various instruments for in vitro diagnostic sample addition or reagent addition. Existing instrument reagent arms such as figure 1 As shown, it includes a reagent arm 101, a rack support part 102 and a reagent needle 103. The debugging method of the reagent arm 101 of the instrument generally uses a pipette to inject a quantitative liquid (such as 100 microliters) into the cuvette 104 , and then according to the height of the liquid level of the reaction cup 104, the height of the reagent needle 103 or the sample needle on the reagent arm 101 is carried out by observing the height of the reagent needle 103 or the sample needle on the liquid...
