Dynamic power wheel 201 rotates, and power wheel 201 drives power belt wheel 202 to rotate again, so in the bottle cap with 204 contact transfusion bottles 5 for the sterilization
The sterilization being before in spring leaf 203 position has been replaced by cleaning with 204, and cleaning box changes to movement after the completion of bottleneck sterilization
Pin platform 3 continues to left movement, the position sensor when the syringe needle 309 of tube for transfusion input reaches the center of transfusion bottle 5 bottle cap
Transmit a signal to controller, controller controls transposition motor 302 to stop, simultaneously driving leading screw motor 308 to drive syringe needle
309 move up, and current limliting folder 314 is followed syringe needle 309 and moved upwardly together, and to a certain extent, syringe needle 309 is gradually inserted and hangs for motion
In bottle 5, Simultaneous Switching bar 312 is also gradually opened current limliting folder 314 so that tube for transfusion turns on, and operator discharges the sky in tube for transfusion
Patient infusion just can be given after gas.When first bottle of medicine will be totally lost, patient oneself or entourage clicks under pipe
The control knob of one bottle of function, syringe needle 309 is extracted and is ended infusion tube 310 simultaneously by device automatically, and device repeats automatically again
Syringe needle is connected on next bottle of medicine process above, operates to the last one bottle of drug injection to close on like this and finishes just need
Call medical personnel again and take pin.After taking pin to finish, medical personnel take off all empty bottles and syringe needle 309, click pipe reset
Control knob, device can automatically restore to original state, in reseting procedure, due between power wheel 201 and power belt wheel 202
It is provided with ratchet mechanism and do not result in sterilization band 204 adverse movements.
By technique scheme, the present invention can realize the automatic disinfection to transfusion bottle bottleneck, and can effectively prevent
Excessive air enters in tube for transfusion, by the needle head replacing of tube for transfusion input to different transfusion bottles it is achieved that electronic replacing
Transfusion bottle, decreases the labor intensity of nursery work person to a certain extent, the automaticity lifting medical apparatus and instruments is had long-pending
Pole meaning.
