10. a kind of course of work of full-automatic infusion set according to any one of claim 1-9, it is characterised in that tool
Body step is as follows：
（1）The transfusion bottle of decoction be will be equipped with by position set in advance, hang on the hook of each transfusion bottle support bar and will hang successively
The woven hose of bottle is placed into the strip inner chamber below corresponding transfusion bottle support bar, and covering cover plate makes baffle plate just be covered in strip
On the outer face of shape inner chamber, dropping liquid is started according to transfusion bottle dropping liquid set in advance order；
（2）When the liquid weight that weighing sensor is sensed in transfusion bottle is less than preset value, while drop counter is shown
Flow velocity be 0 when, controller control stepper motor startup work, stepper motor drive drive screw move downward, drive screw
Follower lever is driven to move downward, pull bar pulls transfusion bottle support bar to be moved downward along axle center under the drive of follower lever, transfusion bottle support
End transfusion bottle on bar is moved upwards along central rotating shaft；Roller moves downward extruding woven hose until defeated under the drive of follower lever
Liquid pipe is closed, then selects next bottle of transfusion bottle to start dropping liquid；
（3）Repeat step（2）Until the liquid conveying in all transfusion bottles is finished, controller sends alarm signal.
