Embodiment Construction

[0053] Hereinafter, a plurality of embodiments are described in detail and examples accompanied by drawings are used as a reference basis of the present invention. In the drawings or descriptions in the specification, the same figure numbers are used for similar or identical parts. And in the drawings, the shape or thickness of the embodiments may be exaggerated and marked for clarity or convenience. Furthermore, parts of the components in the drawings will be described separately. It should be noted that the components not shown or described in the drawings are forms known to those skilled in the art. Furthermore, when it is described that a layer is "on" another layer or a substrate, it may mean that it is directly on the other layer or substrate, or it may mean that an intervening layer exists therebetween.

[0054] Some implementation examples of the present invention are not described in more detail along with the drawings of this application. It should be noted that th...

Abstract

Devices and methods for measuring prothrombin time and hematocrit (HCT%) by analyzing the change in reactance in a sample are presented. A diagnostic device for measuring HCT and prothrombin time of a fluid includes a relative electrode-type sensor device and a blood test card assembly including one or more pairs of electrodes, wherein alternating current (AC) provided by the sensor device is used to measure and calculate prothrombin time and HCT of blood test using the reactance analysis.

Description

[0001] Cross references to related applications [0002] This application is U.S. Provisional Patent Application No. 61 / 353,137, filed June 9, 2010, entitled "Diagnostic Apparatus and Method for Measuring Prothrombin Time and Hematocrit (HCT%) Using Analytical Reactance Changes" The non-provisional patent application of , which is hereby incorporated by reference in its entirety. technical field [0003] The invention relates to a biochemical detection device, in particular to a diagnostic device and method for measuring prothrombin time and hematocrit (HCT%) by analyzing reactance changes. Background technique [0004] Human blood coagulation reaction can be divided into extrinsic pathway (extrinsic pathway) and intrinsic pathway (intrinsic pathway). When the human body is injured, the external pathway will first be activated to control the blood coagulation reaction in the body. In addition to blood, the blood coagulation reaction also needs tissue factor (tissue factor),...
