Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with specific embodiments, which are to explain rather than limit the present invention.

[0032] An anesthesia target-controlled infusion pump controller based on BIS feedback is characterized in that it comprises:

[0033] Control module, which includes communication unit, I / O unit, I2C unit, filter unit, fuzzy PID solving unit, output unit, alarm unit and clock unit;

[0034] The BIS setting module is connected to the communication unit, and sends the BIS reference value to the communication unit, and the communication unit sends it to the fuzzy PID solving unit;

[0035] The power amplifier is connected to the output unit, amplifies the current signal output by the output unit and sends it to the brushless motor; the current sensor monitors the current output by the power amplifier, and sends the current signal to the I2C unit, and then sends the filter unit to the fuzzy PID solving unit and alar...

Abstract

The invention discloses a BIS (BispectralIndex) feedback-based anesthesia target controlled infusion pump controller, which comprises a control module, wherein the control module comprises a communication unit, an I / O (Input / Output) unit, an I2C (Inter Integrated Circuit) unit, a filter unit, a fuzzy PID (Proportion Integration Differentiation) solving unit, an output unit, an alarm unit and a clock unit. According to the BIS feedback-based anesthesia target controlled infusion pump controller, BIS feedback is added, a suitable BIS value reference can be set according to different constitution of each patient, real-time adjustment is performed on the dosage of an anesthetic through a BIS feedback ring, the defects of non-adjustability and low accuracy of an open loop system are overcome, the safety and reliability of an anesthesia process are guaranteed, and higher humanization is realized.

Description

Technical field [0001] The invention belongs to the technical field of anesthesia target-controlled infusion pump control, and relates to an anesthesia target-controlled infusion pump controller based on BIS feedback. Background technique [0002] Anesthesia technology is widely used in the medical industry to relieve the pain of patients during surgery and other treatments, and facilitate the smooth progress of the treatment process. However, the control of the depth of paralysis has always been a problem in the medical field. Insufficient or excessive paralysis can cause serious or even fatal effects on patients. Due to the complex distribution, metabolism and effect of drugs in the human body, ordinary syringe pumps cannot achieve stable drug effects. In order to overcome these shortcomings, target-controlled infusion technology has been used at home and abroad to develop target-controlled infusion pumps and their controllers that are more suitable for human infusion, such as...
