Background technology
Clotting factor is the range protein component that participates in the blood clotting process.Its physiological action is, when angiorrbagia, be activated and PA together and mend leak on the plug blood vessel, this process is called as blood coagulation.Found successively in the last hundred years clotting factor is a lot.
Because wound and operation massive haemorrhage are lost clotting factor; Primary disease such as liver failure, hemophilia also makes the synthetic minimizing of clotting factor, influences coagulation function, and hemorrhage being difficult for ends; Blood component defeated during treatment is incomplete, and the clotting factor deficiency also causes bleeding.During supplement of coagulation factors, need to measure the content of clotting factor, the method of measuring clotting factor now mostly is ELISA (enzyme connects immunosorbent and measures) method, finding speed is slow, the reagent costliness that consumes, the blood sample that needs is originally many, and the content of a certain clotting factor of only single mensuration lacks directive significance for kind that instructs supplement of coagulation factors and dosage.
The D dimer be the activated factor XI, plasma thromboplastin antecedent II of fibrin monomer crosslinked after, a species specificity catabolite that is produced through the fibrinolysin hydrolysis is a specific fibrinolytic process label again.The D dimer derives from the crosslinked fibrin grumeleuse of fibrinolysin dissolving.It is a test understanding Secondary cases fibrinolysis function that the plasma D dimer is measured.Measure the main factor of fibrinolytic system, reach and fibrinolytic system diseases related (as tumour, pregnancy syndrome) for Clinics and Practices fibrinolytic system disease (as DIC, various thrombus), and the thromboembolism treatment monitoring, have great significance.But the thrombolysis effect of the dimeric detection by quantitative quantitative response of D-medicine and can be used for diagnosing, screening the thrombus of new formation.The D dimer is the index of hyperfibrinolysis, and D dimer content height illustrates hyperfibrinolysis.

Sensitive factor on the sensitive layer is the antibody of clotting factor, people's activated clotting factor XII (FXIIa), D dimer, kallikreinogen, high-molecular-weight kininogen or the vWF factor, and described clotting factor is factor I, II, III, V, VI, VII, VIII, IX, X, XI, XII or XIII.
Sensitive factor on the sensitive layer is the combination of the antibody of human blood coagulation, people's activated clotting factor XII (FXIIa), D dimer, kallikreinogen, high-molecular-weight kininogen or the vWF factor, and described human blood coagulation is the combination of factor I, II, III, V, VI, VII, VIII, IX, X, XI, XII or XIII.
The bottom of described substrate is distributed with the sphere pit.Be distributed with sphere pit or the relative sphere pit of spherical surface hill on the described metal level with B.B.P.
The bottom of described substrate is distributed with spherical surface hill.Be distributed with sphere pit or the relative spherical surface hill of spherical surface hill on the described metal level with B.B.P.
Metal level on the described substrate is golden film.
The upper strata of the metal level under the described sensitive layer is golden film, and lower floor is a titanium film.
The utility model can detect clotting factor and the D dimer in the blood more all sidedly, and quick, sensitive.
