Abstract

The present invention discloses an intravenous injection soup dripping speed control method and apparatus. The intravenous injection soup dripping speed control apparatus is composed of a control unit, an execution unit and a feedback unit. The intravenous injection soup dripping speed control method comprises that a user generates a soup dripping speed given value according to an instruction of a working interface in a display device; and then a controller module generates a control instruction according to a fuzzy PID control algorithm, an execution mechanism module (namely a stepper motor) tightens or loosens a soup plastic tube according to the control instruction, and a feedback mechanism module measures the current dripping speed signal again and feeds back the current dripping speed signal to a controller so as to give a next control instruction. The intravenous injection soup dripping speed control method and apparatus have the advantages of high control precision, good effect and stable operation.

Description

technical field [0001] The invention relates to the technical field of medical intravenous infusion control, in particular to a method and device for controlling the drip rate of intravenous injection of medicinal liquid. Background technique [0002] The technical operation related to intravenous infusion is the most important task in nursing. Intravenous infusion is one of the commonly used routes of drug administration in clinic. The amount of liquid medicine given per unit time plays a certain role in the effect of treating diseases . Therefore, in the intravenous infusion operation process, a key link is to control the dripping speed of the medicinal liquid according to the patient's age, physical condition and the type of medicinal liquid to be injected. In the traditional drip speed adjustment process, medical staff need to manually operate the plastic tube clamp to change the flow rate of the liquid medicine by tightening or loosening the plastic tube clamp, and fin...
