Blood coagulation time test and analysis device

Abstract

The invention relates to a blood coagulation time test and analysis device which is characterized by comprising a test piece (22) and a portable main machine, wherein a sample hole (1) for containing a blood sample, a reagent hole (2) for containing a reagent and a capillary tube (3) with a conducting layer (5) are formed in the test piece (22); the sample hole (1), the reagent hole (2) and the capillary tube (3) are communicated with one another in sequence; an air hole (4) is formed in the tail end of the test piece (22), so that liquid can flow in the capillary tube (3); the conducting layer (5) is connected with an electrode interface (7); the electrode interface (7) is accessed into the portable main machine; when the blood sample is mixed with the reagent, the mixed liquid flows along the capillary tube (3); along with the flowing of the mixed liquid, the resistance of the conducting layer (5) changes; the portable main machine is used for measuring the time required by blood coagulation through obtaining a resistance change stop time point.

Description

technical field [0001] The invention relates to a coagulation time test and analysis device, in particular to a thrombin time test device, belonging to the technical field of coagulation test and analysis. Background technique [0002] The process of blood coagulation, referred to as coagulation, is the process of blood changing from a flowing state to a gel state, and it is an important part of the hemostatic function. The coagulation process is a process in which a series of coagulation factors are successively enzymatically activated (commonly known as endogenous and extrinsic coagulation pathways in academia), which produces thrombin protein and promotes fibrinogen to form fibrous thrombus clots. Clinically commonly used test methods include activated partial thromboplastin time (APTT) and prothrombin time (PT) and some other parameters for the prevention and cure of diseases such as thrombosis or fibrinolysis. PT is one of the four routine blood coagulation items, main...

Problems solved by technology

[0005] For the detection of coagulation time in the prior art, the method of detecting the change of the optical properties (degree of light transmission) of the mixture of plasma and reagents, or the method of changing the magnetic properties, and the testing and analysis instruments based on these methods, the above two methods are for blood coagulation The time detection method is not intuitive enough, and the detection equipment is relatively complex, the detection equipment is expensive, and the detection cost is high. At the same time, the monitoring accuracy is often not satisfactory due to equipment or environmental factors
