Fig. 4 is the flow frame diagram that blood sample of the present invention samples preprocess method, referring to Fig. 4, the present invention also provides
A kind of blood sample samples preprocess method, includes the following steps:
Suction pipe is placed in blood sample and carries out blood sampling by step S1, blood sampling.
Step S2 after blood sampling, carries out sample mixing, has the suction pipe of blood sample to be inserted into mixing vessel acquisition, leads to
It crosses suction pipe and punctures diaphragm seal, blood sample injection treatment fluid is housed layer to be mixed with treatment fluid.
The concrete application details of blood sample sampling pretreatment device provided by the invention is described in detail below.
First, the suction pipe 11 in blood sampling portion 10 is placed in blood sample, by siphon principle, blood sample is inhaled automatically
Enter in suction pipe 11, the suction pipe 11 for sucking blood sample is inserted into mixing vessel 21 by vessel port, is guided when suction pipe 11 enters
When slot 2181, the inner wall of guiding piece 218 is contacted with suction pipe 11, with guide suction pipe 11 quickly plant, suction pipe 11 is continued it is downward, directly
Diaphragm seal 211 is punctured to the front end of suction pipe 11, so that suction pipe 11 is inserted in treatment fluid and houses in layer 212, at this point, elastomer 12 is just
It is seated in the opening of sealing container 214.When need not temporarily mix blood sample and treatment fluid, directly protection cap 30 be located in
In vessel port 214, during this, elastomer 12 passes through the hollow open of easy abscission ring, and easy abscission ring is open institute by sealing container 214
It breaks, is wrapped in vessel port 214 to rubber finger sleeve, at this point, 32 ring set of the second lid is on the side wall of mixing vessel,
And second lid 32 is equipped with the engaging corresponding with the bulge loop of mixing vessel of groove ring.It needs to mix blood sample and treatment fluid
When, protection cap is taken out, elastomer 12 is then squeezed, blood sample is injected in treatment fluid, by rocking mixing vessel manually
21 so that mixed liquor is uniformly mixed, finally by the discharge mixed liquor of drain unit 213 of mixing vessel 21.
Blood sample sampling pretreatment device provided by the present invention, by hollow suction pipe automatic sucking blood sample,
Encapsulation process liquid in sample mixing unit, has been reduced as far as the two and has been contacted with external environment, and blood sampling portion and sample are mixed
Conjunction portion is detachably connected the rapid abutting joint that can realize blood sampling and treatment fluid, when mixing, only need to suction pipe be punctured diaphragm seal,
It squeezes again in elastomer injection blood sample to mixed liquor, rocks for use after mixing vessel, needing only need to be by drain list when using
Member is opened, and mixed liquor can be discharged by squeezing elastomer again.Using closing drain plug is finished, residual samples are made together with device
For offal treatment, influence of the sample to environment is effectively reduced.The apparatus structure is simple, fast and easy, mixed liquor manufacturing process
In almost completely cut off completely with external environment, it is high to reduce contaminated probability and biological safety.
Blood sample provided by the invention samples preprocess method, and being placed in progress blood in blood sample by suction pipe adopts
Acquisition is had the suction pipe of blood sample to be inserted into mixing vessel, punctures diaphragm seal by suction pipe, blood sample is injected treatment fluid by sample
Accommodating layer is mixed with treatment fluid, and whole process is isolated with external environment, and the mixed liquor produced will not be polluted by external environment
And biology is safe.
The present invention has been described in detail with reference to the accompanying drawings, those skilled in the art can be according to upper
It states and bright many variations example is made to the present invention.Thus, certain details in embodiment should not constitute limitation of the invention, this
Invention will be using the range that the appended claims define as protection domain.
