Problems solved by technology

Although the Hemochron Signature Elite whole blood micro-coagulation instrument is also a bedside diagnosis, the consumables are relatively expensive, and the entire detection process requires operator feedback and input, and a warm-up time of 30-90 seconds is required (the sample dish is thicker)
Since the instrument determines the time when the blood sample passes through the test path, the surface tension of the test path and the static electricity generated will affect the flow rate of the blood sample, which is likely to cause errors

Abstract

The invention discloses a portable micro-electrode method blood detector, which comprises a casing, an LCD liquid crystal display and a detection circuit system. A portable microelectrode method blood detector and its detection method described in the present invention use a three-electrode system sensor in electrochemical analysis to measure the time required for the sample current to change suddenly after the potential is applied to measure blood in a microsystem environment. The nature of the flow eliminates the differences caused by different operators during the sampling process, and the detection index of blood coagulation and thrombus can reach the second level, realizing a fully automatic "fool-style" bedside diagnosis, not only suitable for hospitals or testing centers, Moreover, it can be used as a preventive diagnostic instrument for home use, and has the characteristics of reliable and stable detection, low use cost, and convenient popular preventive use.

Description

technical field [0001] The invention relates to the technical field of electrochemical detection, in particular to a portable microelectrode blood detector and a detection method thereof. Background technique [0002] The detection indicators of blood cell fragments, thrombus and blood rheology are closely related to various clinical diseases, such as atherosclerosis, cardiovascular and cerebrovascular diseases, diabetes, arteriovenous thrombosis, thromboangiitis obliterans, pulmonary embolism, pregnancy Hypertensive syndrome, disseminated intravascular coagulation, hemolysis, uremic syndrome, chronic obstructive pneumonia, etc. The theory and treatment work research of traditional Chinese medicine on promoting blood circulation and removing blood stasis also involves the problem of hemostasis and thrombus. [0003] The most commonly used equipment in the thrombosis / hemostasis laboratory is a blood coagulation analyzer (hereinafter referred to as a coagulation analyzer). T...
