Detailed description of the invention
This utility model is by being with the cooperation of graduated quantitation tube and piston, when getting liquid, piston is moved up along quantitation tube inwall, close discharging tube and open pipette, owing to there is the confined chamber of vacuum when piston and quantitation tube inwall close contact move upward in quantitation tube, due to the pressure imbalance in confined chamber, by the pipette atmospheric pressure of bottom, the liquid in bottle is pressed in the vacuum chamber in quantitation tube, then is chosen the amount of liquid needing to take by the scale of quantitation tube outer wall; Pipette is closed discharging tube to open, control piston moves downwards through discharging tube and enters in liquid taking bottle by quantitative liquid again;
Further, conveniently control the upwards downward movement of piston, the roof of piston is connected with stayed mast and handle, joystick is controlled by the vertical motion of lever principle to piston;
Further, the outer wall of quantitation tube is provided with fulcrum rod, the top of stayed mast is pulling force point, and the top of fulcrum rod is fulcrum, and pulling force point and fulcrum can rotate, thus passes through the motion of handle control piston;
In addition, control to not need the switch of manpower to pipette and discharging tube, pipette is provided with imbibition check valve and discharging tube is provided with discharge opeing check valve, imbibition check valve only allows liquid to move in quantitation tube, and discharge opeing check valve only allows liquid towards quantitation tube movement outward;
In order to balance the air pressure balance treated in liquid taking bottle, liquid in bottle is constantly sucked in quantitation tube, pipette is provided with breather valve, and in order to ensure the medicinal liquid in not pollution bottle, be provided with air filter in the end of breather valve, the antibacterial in air or particulate matter are stopped;
Consider and easily can be connected with medicinal liquid bottle, the end of pipette and discharging tube can be set to the syringe needle of hard, easily inserts in the medicinal liquid bottle with rubber bottle cap, handled easily;
Meanwhile, in order to the operation of liquid is got in easy imbibition, be provided with bracing frame in the bottom of quantitation tube, for the placement of medicinal liquid bottle supports space.
In order to explanation this utility model clearly, be described below in conjunction with drawings and Examples.
