The invention relates to a micro-blood
detector and a detection method for
rapid detection of markers of acute
myocardial infarction, comprising a blood sample inlet (1), a blood separator (2), a serum sample outlet (3), an
immunoadsorption reaction composed of a device (4), a pH sensitive
field effect tube (5) and a microcurrent detection circuit (6); the blood sample is injected from the sample inlet (1), flows through the
blood separation membrane (9), and the serum enters the
immunoadsorption reactor ( 4), the acute
myocardial infarction marker
antigen in the serum specifically binds to its
antibody, and cross-links with the
enzyme, resulting in a change in the pH value of the reaction solution, and then a change in the current
signal of the pH-sensitive
field effect tube (5), which is then detected by microcurrent The output of the circuit (6) shows the concentration of the tested marker. The present invention uses
whole blood as a biological sample, combines membrane
separation technology with miniature biological sensing elements, integrates
blood separation membrane with miniature pH sensitive
field effect tube, and measures The concentration of acute
myocardial infarction markers can quickly and conveniently realize the clinical detection of acute myocardial
infarction.
