the first processing module is electrically connected with the light beam emitter and the light intensity receiver through wires to receive light intensity signals of the light intensity receiver, the light beam emitter emits light rays with constant light intensity, when liquid medicine water drops exist in an input pipeline in the infusion pot, the light beam emitted by the light beam emitter penetrates through the liquid medicine and is partially refracted and reflected at the liquid medicine water drops, so that the light beam intensity emitted into the light intensity receiver is weakened, when the liquid medicine water drops, the light beam emitted by the light beam emitter is emitted into the light intensity receiver, so that the light beam intensity emitted into the light intensity receiver is enhanced, and the first processing module can obtain the interval time of liquid medicine dropping by counting the interval time of the light intensity signals with large intensity of two adjacent times;
the execution unit includes:
the infusion tube fixing groove penetrating through the second shell is formed in the second shell so as to place an infusion tube;
the cam is rotationally connected in the second shell, and the inner diameter of the infusion pipeline is changed by pressing the infusion pipeline when the cam rotates so as to change the infusion speed;
the driving motor component is arranged in the second shell and is used for driving the cam to rotate;
the second communication module is used for connecting the control part to receive a control signal of the control part to the driving motor assembly;
a worm wheel fixedly connected to the rotating shaft of the cam;
the worm is fixedly connected with the output shaft of the driving motor assembly, is rotationally connected in the second shell and is meshed with the worm wheel to transmit power;
and the handle assembly is arranged on the worm and is used for manually rotating the cam to adjust the infusion speed.
2. The intelligent infusion system of vasoactive drugs according to claim 1, characterized in that it performs the following steps when it is infused:
acquiring the infusion speed, vital signs of a patient and the growth relation of the vital signs and the infusion speed;
comparing patient vital signs with a preset vital sign range;
and adjusting the infusion rate based on the comparison result and the growth relation between the vital sign and the infusion rate.
3. The vasoactive drug intelligent infusion system of claim 1, wherein the second collection unit further comprises:
the first shell is also provided with a fixing part for fixing the second acquisition unit.
4. The intelligent infusion system of vasoactive drug according to claim 1, wherein the outside of the worm is provided with a polygonal blind hole, the handle assembly comprising:
the handle groove is of a groove structure, and one end of the handle groove is fixedly connected with a polygonal column;
the handle is hinged to the handle groove and far away from the polygonal column body, and the handle can rotate into the handle groove.
5. The intelligent infusion system for vasoactive drugs according to any one of claims 1 to 4, characterized in that it further comprises the following steps when it is infused:
and generating an infusion report after the infusion is finished, and recording the infusion report in a hospital server, wherein the infusion report comprises vital sign values and changes, infusion speed values and changes, medicine names, patient information and doctor information.
6. The vasoactive drug intelligent infusion system of claim 5, further comprising:
a fourth acquisition unit for acquiring an infusion amount of the current medicine so that the control section calculates a remaining amount of the infusion patient;
wherein, the control part comprises the following steps when calculating the residual medicine amount:
acquiring the current transfusion medicine information and transfusion medicine quantity;
acquiring an infusion speed curve and infusion time when infusion begins, and calculating the infused volume based on the infusion speed curve and the infusion time;
calculating the residual medicine amount based on the infused liquid amount and the infused medicine amount;
the remaining amount of the drug, patient information, patient vital signs are displayed on a display device.
