The side wall of quantitation tube is provided with liquid relief scale, and the piston is provided with away from the side of quantitation tube to drive piston up and down reciprocatingly to transport
Dynamic piston rod；The suction inlet is provided with the extractor for exiting rifle point, and the extractor includes exiting ring and control is moved back
Go out the action bars of gyration work, the ring set that exits is connected on suction inlet.
Operation principle of the present utility model:A kind of quantitative liquid shifter, it is similar with the structure of syringe including rifle point, quantitative
Cylinder and the piston inside quantitation tube, one end of quantitation tube are the suction inlet of taper, and the other end is circular ports, and rifle point is socketed in
On suction inlet, piston is controlled by piston rod, is pumped in quantitation tube so that suction is produced at rifle point working end,
Solution to be drawn is drawn into quantitation tube, by being provided with liquid relief scale in the side wall of quantitation tube, is used in liquid relief
The volume of liquid is read, waits liquid relief when finishing, it is necessary to which the rifle point on suction inlet is released, by the action bars on extractor,
Ring is released in control, and rifle point is exited at suction inlet.
The beneficial effects of the utility model：The present invention sets extractor on suction inlet, and ring is exited using on suction inlet, leads to
The control of action bars is crossed, rifle point is exited at suction inlet, such words human hand need not contact rifle point, just can be by rifle point from liquid relief
Backed off in device, can or can not thus touch the raffinate on rifle point, safety coefficient is higher, while can also reduce the operating time.
Preferred scheme one, the rifle point are socketed in and exited on ring, and the ring that exits is provided with the shell fragment for supporting rifle point, described
Shell fragment connection controls the action bars that it is inwardly extruded.One of embodiment of extractor, pass through the setting of shell fragment, imbibition
When shell fragment support inside rifle point, it is necessary to when removing rifle point, control operation bar makes shell fragment internal pressure, and shell fragment is not being supported in rifle point
Portion, rifle point can just be released at suction inlet.
Preferred scheme two, it is described exit ring and suction inlet is slidably connected, exit ring and be arranged on the suction inlet of rifle point one end.
Exit ring and rifle point be in same perpendicular and coaxial line, control operation bar, which makes to exit ring downwards, to be moved down, and is supported rifle is sharp downwards
Hold from suction inlet.
As the further optimization to preferred scheme two, protective case is provided with outside the quantitation tube of circular ports side,
The protective case is provided with the sliding groove being slidably connected with action bars.Protective case is fixed by the limited post set on quantitation tube,
Action bars can slide up and down in sliding groove.
Further optimization to above-mentioned prioritization scheme：Filter core is provided with the suction inlet.The impurity of bulky grain can be filtered out,
Prevent from entering in quantitation tube.
To the one-step optimization again of above-mentioned prioritization scheme：The working end of the rifle point is angle.Designed for thick liquid, can
Meet manpower mechanics principle, user effectively to draw clinical samples, the angles of rifle point working end such as similar glycerine or sputum
Indefatigability during a large amount of operations.
