Further optimization the technical program, each conduit of medical use liquid medical liquid mixer is all provided with the check valve of conducting in liquid mixing bunker.
Further optimization the technical program, the material of the encapsulating housing of medical use liquid medical liquid mixer is transparent Teflon.
The utility model beneficial effect is:
It is accurate in scale that liquid dissolves, and dissolves speed fast, economize on dose.
The solvent of liquid and solute are poured in corresponding flux bin and solute storehouse by isolated in advance respectively, and during use, the mixing of simultaneous implantation liquid mixing bunker, can realize matching while using, repeatedly get less, and speed of making up a prescription is fast, can also reduce the waste of liquid.
Rotate regulating wheel, proportional piston transverse shifting under the drive of proportion adjustment leading screw, the position of proportional piston is regulated according to ratio groove, thus the volume in flux bin and solute storehouse is set as requested, open switch valve, solvent and solute enter mixing in liquid mixing bunker, this makes it possible to the liquid dissolving out preset ratio accurately.
Check valve installed by conduit, and inject piston and often have certain elasticity for keeping sealing, having elasticity then there will be elastic deformation, and elastic deformation can cause the Volume Changes of injecting storehouse, and admixing medical solutions is refluxed.Check valve can prevent the liquid adverse current mixed from pushing back in note storehouse, pollutes or changes the purity of injecting solute or solute in storehouse.
Polytetrafluoroethylene (PTFE) has extremely strong not viscosity and corrosion resistance, and solute and solvent are not easy to adhere on encapsulating housing inwall all very much, can conveniently clean so on the one hand, can improve the slickness of inner wall surface on the other hand, reduces and injects resistance.
