Detection method of semi-automatic coagulation analyzer

Abstract

The invention discloses a detection method of a semi-automatic coagulation analyzer. The detection method includes the steps of: 1) starting the analyzer and entering main menu; 2) selecting detection object and preparing a reagent and a sample; 3) sucking the reagent into a detection hole and pre-heating the reagent; 4) performing zero point tracing, adding blood plasma into the detection hole filled with the reagent, and sending a measurement command to a measurement part; 5) after the measurement is completed, reading a measurement result by a host computer; 6) printing the result by a printer; 7) selecting whether the measurement is carried out continuously or not by the host computer; and 8) finishing measurement, wherein a measurement step includes the following operations: a) initializing the system when the measurement part receives the measurement command; b) waiting the compound whether the measurement is carried out by the host computer; c) regulating a signal zero point before every time that the blood plasma is added into the detection hole filled with the reagent by means of a zero point automatic set circuit, and converting a voltage signal into a digital signal through an ADC unit; and d) reading the digital signal by a MCU and performing data analysis by the MCU to obtain measurement data and diagnosis report. The method is simple in operation, has high efficiency and detection precision and is reduced in cost.

Description

technical field [0001] The invention relates to the field of coagulation analysis, in particular to a detection method for a semi-automatic coagulation analyzer. Background technique [0002] With the improvement of medical technology, coagulation analysis has become a routine analysis method in hospitals. Semi-automatic coagulation analyzer is a commonly used coagulation analyzer, which is mainly divided into magnetic bead method and optical method. Now the most commonly used coagulation analysis The instrument is based on the magnetic bead method. The magnetic bead coagulation analyzer uses the electrical signal generated by the cutting of the magnetic force line during the swing of the magnetic bead to monitor the swing amplitude of the magnetic bead. When the swing amplitude of the magnetic bead decays to 50%, the coagulation end point is determined. The problem with this detection method is that magnetic beads need to be added for each detection, which makes the detecti...
