Channel；Space between the sealing valve and the piston is cavity for mixing drugs, and being provided in the sealing valve makes cavity for mixing drugs select one
The medicine liquid channel being connected to the drug delivery channel of a root puncture needle.
Two puncture needles are L shape needle, and the root of the puncture needle is fixedly connected on the side wall of the mixed cylindrantherae；Institute
Stating the medicine liquid channel in sealing valve is L shape channel.
The root of two root puncture needles is fixedly connected in the bottom of the mixed cylindrantherae；Medicine liquid channel in the sealing valve is
Through the linear type channel of the sealing valve top and bottom.
The connecting rod penetrates the center of the piston and piston rod along axial direction, and the piston rod is provided with confession along its axial direction
The channel of the connecting rod sliding, is provided with the keyway axially extended, the side of the connecting rod on the inner wall in the channel
Wall be provided be slidably fitted in it is convex stupefied in the keyway.
Because the utility model adopts the above technical scheme, it has the following advantages: the utility model can improve mixed medicine
Process specifically wherein will be inserted into infusion bottle by a root puncture needle, another transfusion needle insertion is equipped with the cillin bottle of medicinal powder；Rotation
Handle makes the medicine liquid channel in sealing valve be connected to (another root puncture needle at this time with the drug delivery channel of the puncture needle of insertion infusion bottle
It is not connected to medicine liquid channel), then upper handle, sucks cavity for mixing drugs for the liquid in infusion bottle using suction；Then hand is rotated
Handle, being connected to medicine liquid channel in sealing valve with the drug delivery channel of the puncture needle of insertion cillin bottle, (another root puncture needle is not at this time
It is connected to medicine liquid channel), pushing handle is then played, the liquid in cavity for mixing drugs is pushed in cillin bottle, rocking cillin bottle makes medicinal powder
It is dissolved in liquid, later upper handle, cavity for mixing drugs will be sucked dissolved with the liquid of medicine；Rotating handle again makes the medicine in sealing valve
Liquid channel is connected to the drug delivery channel of the puncture needle of insertion infusion bottle, and lower pushing handle will push to infusion bottle dissolved with the liquid of medicine
In, so far complete mixed medicine process；Having the above process to can be seen that entire mixed medicine process does not make liquid in infusion bottle and outer
Portion's air directly contacts, it is possible thereby to avoid the pollution of medical fluid.
