Method and device for detecting blood viscosity and hematocrit by using one instrument

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 anticoagulantprocessing, 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.

Description

Technical field [0001] The present invention relates to a method and equipment for measuring blood viscosity and blood pressure by one machine. The method uses a fully automatic measuring equipment. The fully automatic measuring equipment includes a stirring needle device, a sample injection needle device, and a rotating blood rheology Measuring device, packed scan measuring device, automatic control circuit and matching program. Background technique [0002] Chinese Patent 200520104155.6 discloses a fluid viscosity measurement device based on a sample capillary circuit. It has a frame with a sample needle mounting frame on which a capillary type sample needle is fixed. , The sample injection needle is communicated with a sample injection pump through a sample injection pipeline, a pressure sensor is arranged on the injection needle body or the sample injection pipeline, and the pressure sensor is connected to a solution processor through a data line. Connected, the solution pro...

Problems solved by technology

However, the patent can only measure plasma viscosity or whole blood viscosity

It is impossible to measure plasma viscosity, whole blood viscosity and hematocrit with one machine. Therefore, it is necessary to propose a new method and equipment for measuring blood viscosity and blood pressure volume with one machine.
