Catheter stopper more than graduation mark is opened, and that realizes the measurement of different volumes liquid facilitates selection.
Preferably, the conduit is uniformly arranged every the scale of 20ml from top to bottom.It can also be according to the range of graduated cylinder
Appropriate adjustment is carried out to the setting quantity of conduit, position, can be such as uniformly arranged every the scale of 10ml, the scale every 5ml is equal
Even setting etc..
Preferably, the conduit is round tube, and conduit and the curved surface lower part of stack shell junction and graduation mark are tangent.The structure
Design can make liquid extra in graduated cylinder after conduit discharge, and the liquid level recess in graduated cylinder is located just on required graduation mark.
Preferably, the catheter stopper include interconnect cylindrical plug and plug handle, cylindrical plugs body length with lead
Length of tube is identical, and cylindrical plug top is cambered surface, and cambered surface curvature is consistent with stack shell inner wall.The design is so that catheter stopper is filled in
After conduit, the cambered surface and stack shell inner wall on cylindrical plug top on the same face, avoid conduit setting bring well
Error.
Preferably, conduit is provided on the graduation mark of the stack shell the top.
Preferably, the conduit and catheter stopper are plastics or rubber material.Plastics and rubber wear-resisting are non-friable, user
Just.
Preferably, the catheter diameter is 2-5mm.Suitable internal diameter can be selected according to the size of graduated cylinder.
Preferably, the lower end of the conduit is removably connected with drainage tube.In graduated cylinder extra liquid from conduit outflow after,
Waste liquid tank is flowed by drainage tube, is avoided dirty and messy on workbench.
Preferably, the conduit and angle formed by stack shell outer wall are 45 °~60 °.The design can guarantee more in graduated cylinder
Remaining liquid is flowed out from conduit automatically.
Preferably, the drainage tube is rubber tube, and rubber tube flexibility is good, facilitates the outlet of rubber tube being placed into waste liquid
Slot.
The utility model in terms of existing technologies, has the advantages that
1) the utility model structure is simple, and when measuring liquid, extra liquid relies on self gravity in graduated cylinder, automatically from leading
Pipe discharge, it is convenient to use, it even if having poured into surplus liquid into graduated cylinder, can also be discharged at once, reach the mesh accurately measured
's.
2) conduit is set as round tube and the curved surface lower part and the tangent design of graduation mark of conduit and stack shell junction, can make
After conduit discharge, the liquid level recess in graduated cylinder is located just on required graduation mark extra liquid in graduated cylinder, guarantees to measure quasi-
Exactness.
3) according to the liquid volume of required measurement, graduation mark conduit below is blocked with catheter stopper, more than graduation mark
Catheter stopper open, realize different volumes liquid measure facilitates selection.
4) cylindrical plugs body length is identical as catheter length, and cylindrical plug top is cambered surface, cambered surface curvature and stack shell
Inner wall is consistent.After the design is so that catheter stopper fills in conduit, the cambered surface and stack shell inner wall on cylindrical plug top are in the same face
On, conduit setting bring error is avoided well.
5) design of detachable drainage tube, so that liquid extra in graduated cylinder flows into after conduit outflow by drainage tube
Waste liquid tank avoids dirty and messy on workbench.
