Abstract

The invention relates to a method and a device for detecting blood viscosity and hematocrit by using one instrument. In the invention, full-automatic detection equipment, including a stirring pin device, a sample loading pin device, a capillary viscosity measurement device, a rotary type blood rheological measurement device, a hematocrit scanning measurement device, a computer device based automatic control circuit and a matched program of the automatic control circuit is used. The detection method comprises the following steps of: collecting a patient blood sample, carrying out anticoagulant processing, injecting into a sample tube, and centrifuging; putting the sample tube in a sample tube frame, conveying the sample tube frame to a hematocrit test position for detecting, and storing hematocrit data; conveying the sample tube frame to a blood viscosity test position for detecting plasm viscosity and storing data; stirring the blood sample into whole blood by the stirring pin device, and reading the blood viscosity data by the rotary type blood rheological measurement device; and processing the detected data by a resolving processor. By using the full-automatic detection manner disclosed in the invention, operators avoid contacting the patient blood sample directly and cannot be polluted, all the processes of sample loading process, detection process and cleaning process are all accomplished by instruments automatically, thereby improving the detection speed and accuracy of clinical examination.
