Debugging quantitative method

Abstract

The invention discloses a debugging quantitative method. The method comprises the following steps: S1, collecting test data of a principle machine for a quantitative volume V; s2, determining a function relational expression V = AN + B of the quantitative volume V and the quantitative pulse value N through linear fitting, wherein A and B represent constants; s3, setting instrument parameters; s4, determining a benchmark debugging pulse value N1 corresponding to the quantitative volume V by referring to the test data of the principle machine in the step S1; s5, controlling the stepping motor to complete sample adding according to the reference debugging pulse value N1; s6, weighing the weight of the debugging container after sample adding, and automatically calculating to obtain a debugging volume V1; s7, judging whether the debugging volume V1 meets the accuracy requirement of the quantitative volume V or not; if not, correcting the debugging pulse value N1, and repeatedly executing the steps S5 to S7; s8, debugging the volume V1 to meet the accuracy requirement of the quantitative volume V, and outputting a debugging pulse value N1 as a quantitative pulse value of the quantitative volume V in the instrument.

Description

technical field [0001] The invention relates to an instrument for adjusting and quantifying by weighing method in the field of in vitro diagnosis, in particular to an adjusting and quantifying method. Background technique [0002] In vitro diagnostic instruments, such as automatic chemiluminescent immunoassay analyzers, biochemical analyzers, etc., in the process of diagnosis and analysis, first of all, "analytical pretreatment" is required, that is, quantitative addition, distribution, dilution or mixing of the liquid to be tested is required . The "pre-analysis" process is generally completed by a micro-syringe / pump, a matching tube valve, a sampling needle / Tip, and a precision stepping motor that integrates drive, control, and communication functions. It is controlled by the pulse signal value of the stepping motor. The amount of the liquid to be tested can be quantitatively added. In order to ensure the accuracy of quantitative sample addition, it is necessary to deter...

Problems solved by technology

[0004] Moreover, this method generally requires computer-assisted debugging personnel to repeatedly perform operations such as weighing records, converting volumes, etc., and constantly trial and error to find out the motor pulse value corresponding to the required sample amount. The debugging efficiency is low, and it is easily affected by the technical level of the debugging personnel, Due to the influence of individual differences in debugging instruments and differences in debugging pulse values, it is difficult to control the inter-group difference and inter-station difference of instruments
