In second air bag；The other end of the capillary is equipped with micropore；The micropore is located in protective case；The capillary
In the structure of both ends open inner hollow.
Further, the seal pipe is glass tube.
Further, the annular folding line groove of each setting one at 5 to 10mm of the both ends apart from seal pipe.
Further, the internal diameter of the capillary is 0.5 to 2.0mm.
A kind of application method of closed blood sampling diluter, steps are as follows:
S1, the annular folding line groove at seal pipe both ends is fractureed, and the dilution in seal pipe is made to flow into the first air bag
It is interior；
Capillary is carried out horizontal or slant setting, then through capillary action by S2, the protective case for pulling up the capillary other end
So that the capillary other end is acquired blood, acquisition is automatically stopped when the blood of acquisition reaches micropore；
S3, protective case is socketed in the capillary other end again, then squeezes the first air bag so that the dilution in the first air bag according to
Secondary to be converged after seal pipe, the second air bag with the blood acquired in capillary, mixed liquor is extruded together after converging
To protective case, blood completes dilution mixing in protective case.
Further, the concrete operations to fracture in the step S1 are as follows: place the first air bag upwards, simultaneously by seal pipe one end
And the annular folding line groove being located in the first air bag fractures；Entire diluter is rotated, the first air bag is placed downwards, then will
The seal pipe other end and annular folding line groove being located in the second air bag fractures, dilution in seal pipe flows into the at this time
In one air bag.
Beneficial effects of the present invention
The present invention is additionally arranged seal pipe and the second air bag, dilution is encapsulated into seal pipe in advance, seal pipe of the invention can
Preferential glass tube, and be respectively set an annular folding line groove at the both ends of seal pipe, the both ends of such seal pipe can at any time into
The capable connection that fractures, entire inventive structure is ingenious in design, solves the drawbacks of dilution volatilization.
