Abstract

The invention discloses a closed-loop inhalation anesthesia control system. The system comprises a ventilation device, a gas recovery device, a breathing circuit, gas delivery pipelines, an anesthetic vaporization device, an anesthesia depth monitoring device, an automatic anesthetic conveying device, a central control device, communication lines, a medicine conveying pipeline and an inhalation anesthetic, wherein the central control device is connected with the anesthesia depth monitoring device and the automatic anesthetic conveying device through the communication lines, the ventilation device, the anesthetic vaporization device and the gas recovery device are connected with the breathing circuit through the gas delivery pipelines, and the automatic anesthetic conveying device is connected with the anesthetic vaporization device through the medicine conveying pipeline. Automatic closed-loop administration of the inhalation anesthetic is realized; insufficient or excessive administration is avoided and the anesthesia safety is enhanced; the workload of an anesthetist is reduced and human errors are reduced.

Description

technical field [0001] The invention relates to the field of medical anesthesia control, in particular to a closed-loop inhalation anesthesia control system. Background technique [0002] Closed-loop control (closed-loop control system) is an automatic control system composed of a signal forward path and a feedback path to form a closed loop, also known as a feedback control system. In order to realize closed-loop control, the output must be measured, and the measured result is fed back to the input terminal to subtract the input to obtain the deviation, and then the deviation is directly controlled to eliminate the deviation, and the entire system forms a closed loop. The closed-loop anesthesia control system is an automatic control technology. After inputting a certain amount of anesthetics to the patient, the computer analyzes the various physiological indicators and drug efficacy information of the patient to calculate the dosage and rate of administration, and then feed...
