Embodiment Construction

[0029] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments.

[0030] see figure 1 Structural schematic diagram of the present invention. The illustrated blood coagulation time measuring device includes a light source 3, a light receiving element 4, two driving coils 1 and 2, a test cup 7, a steel ball 8 and a skeleton 6, the light source 3, the light receiving element 4, two driving coils 1, 2 And the test cup 7 is all arranged on the skeleton 6 . In this embodiment, the light source 3 is a solid light source, which can emit measurement light, and the measurement light is monochromatic light, and the light receiving element 4 is a silicon photocell, which can sense the measurement light emitted by the light source 3. Light intensity; the light source 3 and the light receiving element 4 can also be other corresponding light emitting elements and light receiving elements that can generate photoel...

Abstract

The invention discloses a blood coagulation time measuring device, which comprises a light source, an optical receiver element, a test glass in which a detected sample is placed and a steel ball in the test glass, the test glass is arranged between the light source and the optical receiver element, and the three parts are all positioned on the same axial line, the steel ball can be vibrated to and fro in the detected sample in the test glass along the direction vertical to the axial line, and measuring light sent by the light source reaches the optical receiver element after passing through the detected sample and the steel ball in the test glass; and the invention also discloses two methods of an optical method and a mechanical method for measurement by applying the measuring device. Thedevice and methods have the advantages of simple structure, low costs, realizable two test functions of the optical method and the mechanical method.

Description

Technical field: [0001] The invention relates to a medical coagulation analysis instrument and its method, in particular to a blood coagulation time measuring device and its measuring method. Background technique: [0002] The coagulation analyzer is a detection instrument used to detect individual blood coagulation indicators. According to the different working principles it adopts, there are two methods of coagulation analysis and testing, mechanical method and optical method, and two different measuring devices corresponding to them. No matter which The key of this detection method is to correctly judge the termination time of blood coagulation reaction. Coagulation analyzers can detect a variety of blood coagulation indicators, blood coagulation time is one of them, typical tests include: prothrombin time, activated partial thrombin time, thrombin time, fibrinogen, etc. [0003] The coagulation analyzer using the mechanical method includes two sets of coils perpendicula...
