the single chip microcomputer U1 outputs signals to enable the lifting rod 13 to drive the medicine carrying wheel disc 8 to rise by a set height, and after rising is completed, the single chip microcomputer U1 outputs signals to enable the medicine carrying wheel disc 8 to rotate by a set angle; subsequently, the single chip microcomputer U1 outputs a signal to enable the electric drug-carrying wheel disc 8 of the lifting rod 13 to descend to a set height, and at the moment, in the descending process, a needle on the infusion tube 5 pricks a new infusion bottle 7 completely to perform infusion operation of the new infusion bottle 7.

If the last bottle, singlechip U1 output signal drive alarm BJ sends the alarm sound, and simultaneously, singlechip U1 sends the warning information to the nurse station through GSM module U6. If the liquid in the infusion bottle 7 in the last bottle is lower than the threshold value and exceeds 60s, the single chip microcomputer U1 outputs a signal to enable the lower clamping piece 16 to descend by the driving of the vertical screw rod 26 for a set value, then the single chip microcomputer U1 outputs a signal to enable the movable piece 31 to rotate for a set value, and at the moment, the movable piece 31 and the fixed piece 30 can clamp the infusion tube 5 tightly, so that the liquid in the infusion tube 5 is cut off, air is prevented from entering the blood vessel of a patient, and the safety of the patient in the using process is guaranteed.

For the heating plate, the patient can select whether to press the heating button S2 on the vertical rod 3 according to the self condition, if the heating button S2 is pressed, the single chip microcomputer U1 can receive the signal, the single chip microcomputer U1 outputs a signal to drive the heating plate to be connected with a power supply, the heating plate works, the infusion tube 5 passes through the heating cylinder 12, and the heating of liquid in the infusion tube 5 is realized.

The utility model provides an integration area monitoring infusion set can hang and establish a plurality of infusion bottles, can realize the control of infusion in-process liquid level simultaneously, and it is convenient to realize, and reasonable in design has improved the degree of safety of infusion in-process.
