Further, described transfusion unit has two or more, and the transfusion state of each transfusion unit is independent on control station Display and operation.
Further, described transfusion state refers to the liquid level of flow of infusate, remaining time, end warning and changes liquid notice.
Beneficial effects of the present invention:
(1) transfusion speed is stable: control centre uses PLC programming Control, uses PID to adjust according to the decrease speed of liquid level Joint, automatically controls electronic valve openings of sizes, it is ensured that transfusion speed is stable;
(2) conduit of each insertion medicament reservoir is with liquid level sensor, passes the signal to control station display screen, collection The liquid level of each medicament reservoir of middle display and remaining time, it is simple to nurse station personnel observe the reasonable arrangement time in time.
(3) when each transfusion unit has multiampule medicine to need to change, system can be changed automatically: when one bottle of liquid has been infused Bi Shi, three-way valve and electrodynamic valve can automatically switch to other one bottle and continue transfusion, reduces medical personnel's workload;It is simultaneously emitted by Prompt tone reminds medical personnel to note.
(3), when transfusion closes to an end, the most independent prompting medical personnel that sound the alarm process in time.
