It connects, the bottom end outlet connection of solenoid valve and capillary.
Preferably, further including pressure sensor, it is connect respectively with gas chamber and control assembly.
A kind of tester, including above-mentioned lectin from hemolymph testing agency.
The utility model has the beneficial effects that
The utility model is arranged to capillary by will test the channel of blood plasma viscosity, so that blood using amount will not be excessive,
And time of the blood plasma by channel can be greatly shortened, and then solve asking for existing blood rheology test instrument detection time length
Topic.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of lectin from hemolymph testing agency provided by the utility model.
In figure:
1, capillary；2, detection components；3, control assembly；4, negative pressure pump；5, gas chamber；6, solenoid valve.
Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1, it is the structural schematic diagram of lectin from hemolymph testing agency provided by the utility model.Lectin from hemolymph detection
Mechanism includes capillary 1, at least two groups detection components 2, control assembly 3, negative pressure pump 4, gas chamber 5, solenoid valve 6, temperature adjusting group
Part and pressure sensor (not shown), in which:
Capillary 1 is glass tube, and its caliber is 0.5mm-0.8mm, and caliber is set according to blood cell size, cannot mistake
Greatly can not be too small, it otherwise will affect the accuracy and consistency of measurement.Capillary 1 is used to provide the channel of detection to blood plasma,
The utility model is arranged to capillary 1 by will test the channel of blood plasma viscosity, so that blood using amount will not be excessive, and can be big
Amplitude shortens time of the blood plasma by channel, and then solves the problems, such as that existing blood rheology test instrument detection time is long.
In the height direction, at least two groups detection components 2 are selected in the outside of capillary 1, present embodiment
Two groups of detection components 2 set up and down, detection components 2 are used to detect blood plasma by the signal of predeterminated position in capillary 1, in advance
If position is preferably the location of detection components 2, so set, can more survey to the viscosity of blood plasma to direct convenience
Amount.Specifically, every group of detection components 2 include infrared transmitter and infrared remote receiver, and the two is divided into the two of capillary 1
Side, when blood plasma component 2 after testing, infrared remote receiver cannot receive infrared light, i.e., can generate signal at this time (can be referred to as to cut
Varying signal).
Control assembly 3 is electrically connected with detection components 2, for receiving (shear) signal of the transmission of detection components 2, and is recorded every
Time corresponding to signal twice is passed through a series of formula operations again, obtained by secondary (shear) signal corresponding time, control assembly 3
To the blood flow variate of the plasma specimen.
Temperature-controlled package is for keeping the temperature of capillary 1 constant, specifically, temperature-controlled package include heated body,
Heating module and temperature control chip, heated body are coated on the outside of capillary 1, and heating module is for heating heated body, temperature
Degree control chip is used for heating and temperature control in preset temperature, and in this embodiment, preset temperature is selected as 37 DEG C.
The both ends of gas chamber 5 are connect with negative pressure pump 4 and solenoid valve 6 respectively, and solenoid valve 6 is connect with the bottom end outlet of capillary 1,
Pressure sensor is connect with gas chamber 5 and control assembly 3 respectively, by the control of negative pressure pump 4 so that testing agency keeps negative pressure, such as
This can be conducive to blood plasma and pass through capillary 1.
The specific working mode of above-mentioned device is as follows: solenoid valve 6 is closed, and gas chamber 5 is taken out negative pressure by the work of negative pressure pump 4, is passed through
Pressure sensor detects pressure value, and after 5 pressure value of gas chamber is stablized, negative pressure pump 4 stops working and operating stably；Once pressure passes
Sensor senses 5 pressure change of gas chamber, then 4 perseveration of negative pressure pump, until pressure value is stablized in preset pressure value in gas chamber 5.
At this point, blood plasma is added in capillary 1, solenoid valve 6 is opened immediately, and gas chamber 5 is connected to capillary 1, and negative pressure drives blood plasma to flow through
The predeterminated position of capillary 1.After the completion of test, cleaning solution is added in capillary 1, and negative pressure pump 4 is under 6 opening state of solenoid valve
Perseveration ensure that the cleaning of testing agency so that capillary 1 be cleaned up, and then be dried by temperature-controlled package
Capillary 1.
