Referring to Fig.1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, application method of the invention：（1）By pull rod 44 by mounting base 4 from opening
It is pulled out in mouthful, then elastic rubber pipe 23 is put into mounting base 4, and the latter end of the first connecting tube 21 is allowed to be in placing groove 400；
（2）Mounting base 4 is minimized by place by pull rod 44 again；The leading portion of second connecting tube 25 is positioned in L-type groove body 12；It will control
Device 10 processed is fixed on by fixture 100 on hanging bottle support b, then the first connecting tube 21 is accessed infusion bottle a；（3）It is aobvious by touching
The input of display screen 17 includes the relevant infusion information of medicine name, transfusion speed and amount of infusion etc., by the Parameter Switch mould of circuit board 31
Block and programmable processor according to transfusion speed and amount of infusion using the reduction formula to prestore calculate corresponding motor rotary speed and
The motor rotation number of turns；（4）32 invariablenes turning speed of motor is controlled according to motor rotary speed by programmable processor and motor control module
Work, and the accumulative rotating cycle of motor 32 is recorded in real time；32 driving cam 34 of motor rotates, and week is carried out to elastic rubber pipe 23
Phase property squeezes；Due to the presence of the first check valve 22 and the second check valve 24 so that the liquid in infusion bottle a is through the first connecting tube
After 21 enter elastic rubber pipes 23, can only unidirectionally it be flowed from the second connecting tube 25, using flowing into patient after the second connecting tube 25
In vivo；（5）When the accumulative rotating cycle that circuit board 31 is recorded reaches said motor rotating cycle, circuit board 31 judges this time
Infusion task is completed, and is just automatically stopped motor 32 by circuit board 31 and is sent out the alarm signal that infusion is completed（When motor 32 stops,
Liquid should also be remained in woven hose 20, be not in excessive and be difficult to the air emptied, medical staff is facilitated more to renew
Infusion bottle a continues subsequent infusion work）.（6）When the second connecting tube 25 blocks（For example, the second connecting tube 25 occurs sternly
It bends again）, when causing its hydraulic pressure excessive, overflow valve 1521 is automatically opened because upstream pressure is more than threshold values, partially liq shunting
To the first connecting tube 21；The resistance of the elastic rubber pipe 23 of the extruding of cam 34 simultaneously becomes larger so that the load of motor 32 increases, work electricity
It flows and increases and be more than default safety value, the programmable processor and motor control module of circuit board 31 judge that appearance is abnormal, just certainly
It is dynamic to stop motor 32 (overload protection of circuit board 31), and abnormal alarm signal is sent out by alarm module.
The specific implementation mode of the present invention is above are only, but the design concept of the present invention is not limited thereto, it is all to utilize this
Conceive the change for carrying out unsubstantiality to the present invention, the behavior for invading the scope of the present invention should all be belonged to.
