HCT measuring device and method and chemiluminiscence instrument with HCT measuring device

Abstract

The application discloses an HCT measuring device and method and a chemiluminiscence instrument provided with the HCT measuring device. The HCT measuring device comprises a shell, a liquid injection port is formed in the shell, the liquid injection port is communicated with a measuring cavity, and the other end of the measuring cavity is connected with a liquid pumping device; a measuring mechanism comprises an insulation sealing device and a graphite electrode plate, the insulation sealing device and the graphite electrode plate are pressed and fixed in the measuring cavity through an electrode pressing plate, and the electrode pressing plate is fixedly connected to the shell; the graphite electrode plate is in direct contact with a probe and is used for detecting the resistivity of a detected whole blood sample; a control analysis module arranged in the shell comprises a signal generator, a signal acquisition and processing module and a central processing unit which are connected with one another; the signal generator is used for outputting a driving signal to a whole blood sample, the signal acquisition and processing module is used for acquiring an electric signal detected by the probe and converting and transmitting the electric signal to the central processing unit after processing the electric signal, and the central processing unit is used for converting and calculatingresistivity and an HCT value.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to an HCT measuring device, a chemiluminescent instrument equipped with the HCT measuring device, and a measuring method of the HCT measuring device. Background technique [0002] HCT (hematocrit) is hematocrit, also known as hematocrit, which refers to the proportion of red blood cells in a certain volume of whole blood. Traditional chemiluminescent instruments can only measure the HCT of whole blood samples outside the instrument by other means, usually through the Wennen method. When measuring HCT, a special test tube, namely Wennen tube, is required for the specified time and speed. Centrifugation will eventually make the red blood cells completely compacted at the bottom of the test tube, and then read the value of HCT. The operation is complicated and the measurement time is long. Not only is it a waste of time, but also requires additional samples and specia...
