1. the plasma viscosity measuring method of a capillary pipeline is characterized in that:

  • use the plasma viscosity measurement mechanism of an application of sample capillary pipeline to carry out data acquisition, utilize and resolve processor the data of gathering are handled, export the viscosity data of tested blood plasma;

    A, in the tested liquid sample cup, inject tested liquid, in tested liquid sample cup, put into tested blood plasma, described plasma viscosity measurement mechanism is in 20 ℃



    40 ℃

    the environment, make the fluid temperature in all sample cups reach uniformity;

    B, the described plasma viscosity measurement mechanism of startup;

    Sample needle is extend in the tested liquid in the tested liquid sample cup;

    Use sample needle to draw tested liquid according to predefined constant rate parameter;

    Collect the pressure parameter P1 of said tested liquid through the pressure transducer on the application of sample capillary pipeline, and this pressure parameter is sent to resolves processor;

    C, control sample-adding pump carry out the stock layout operation, with the tested liquid emptying of drawing;

    After the tested liquid emptying, can also carry out once flushing through service sink, use cleaning fluid that liquid wash residual in the sample needle is clean, said cleaning fluid adopts pure water;

    D, control sample-adding pump are inhaled a kind operation once more;

    Sample needle is extend in the tested blood plasma in the tested liquid sample cup;

    Use sample needle according to drawing tested blood plasma with the identical flow parameter of absorption tested liquid;

    Collect the pressure parameter P of tested blood plasma through described pressure transducer, and this pressure parameter is sent to resolves processor;

    E, use and to resolve processor, draw tested plasma viscosity data according to calculating formula V=Vgd * (P-P0)/(P1-P0) calculate;

    This viscosity data is the viscosity data value under the testing environment temperature, or demarcates the viscosity data value under the temperature;

    The plasma viscosity measurement mechanism of said application of sample capillary pipeline has a frame, and said frame is provided with the sample needle erecting frame, fixing capillary type sample needle on the said sample needle erecting frame, and this sample needle is communicated with a sample-adding pump through an application of sample pipeline;

    On said application of sample needle body or said application of sample pipeline, a pressure transducer is set;

    Said pressure transducer resolves processor and is electrically connected with one through data line;

    The said processor that resolves is installed on the control circuit;

    The said processor that resolves is electrically connected with said sample-adding pump input end through control line, and said sample-adding pump is a ram pump;

    The endpiece of said sample-adding pump is communicated with a bottle for handling liquid toilet or cosmetic substance through flexible pipe, on the table top below the described capillary type sample needle, the sample cup fixator is set, and is provided with tested liquid sample cup and tested liquid sample cup in the said sample cup fixator;

    The right part of said table top also is provided with one and washes the pin pond, and this is washed the pin pond and is communicated with waste liquid bottle through flexible pipe;

    Said erecting frame is a spiral arm lift erecting frame, and column goes up and down in the drive lower edge of drive motor, turn-screw, and the axial line around column under the driving of motor, belt gear rotates;

    Said sample cup fixator is the sample disk of a rotatable transposition, and this sample disk is fixed through vertical shaft device and frame, drive by motor, belt gear and realize the rotation transposition, the control end of this motor with resolve processor and be electrically connected.
