[0050]

[0051] First, an electrical characteristic measuring device according to a first embodiment of the present invention will be described. As mentioned above, measurements of electrical properties of blood are affected by blood sedimentation. In addition, it has been reported that the dielectric constant of non-coagulated blood is changed by blood sedimentation (K. Asami, T. Hanai, Colloid and Polymer Science, vol. 270, 1992, p. 78-84). However, it is not known what influence exists on blood sedimentation in performing a blood coagulation test using a dielectric constant, and it has not been studied how such an influence can be eliminated.

[0052] Therefore, in order to perform more accurate measurement of blood in an electrical characteristic measuring device such as a dielectric coagulometer, it is necessary to adopt a method free from the ...

Abstract

Provided is an electrical characteristic measurement device that can precisely measure the electrical characteristics of blood. The electrical characteristic measurement device, which has a measurement unit that measures the electrical characteristics of blood that is the subject of measurement and filling a sample vessel by imposing a voltage between an electrode pair of the sample vessel provided with one or more pairs of electrodes, is provided with a rotary mechanism that rotates the sample vessel to any given angle, and the electrical characteristics of blood are measured over time by the measurement unit while rotating the sample vessel by means of the rotary mechanism, for example, intermittently in a rotational manner and / or alternating turning forward and turning backward.

Description

technical field [0001] The present technology relates to an electrical characteristic measuring device for measuring electrical characteristic of blood. More specifically, the present technology relates to a technology for measuring electrical characteristics of blood in time series and acquiring information such as coagulability of blood and the like. Background technique [0002] Antiplatelet or anticoagulant agents are administered prophylactically to patients susceptible to thrombosis or to healthy individuals. Examples of patients susceptible to thrombosis include patients with diabetes, arteriosclerosis, cancer, heart disease, and respiratory diseases; patients during surgery, and patients taking immunosuppressants. In addition, examples of healthy people who are susceptible to blood clots include pregnant women and the elderly. As the antiplatelet aggregation agent, acetylsalicylic acid and the like are used; and as the anticoagulant agent, warfarin, heparin, active...
