闭环肌松药效监测及注射方法和闭环肌松注射装置

Abstract

The invention discloses a closed loop muscle relaxation iatrical effect monitoring and injecting method and a closed loop muscle relaxation injecting device. The method comprises the specific steps of: acquiring muscle myoelectricity feedback actions of a patient through an independently developed muscle relaxation monitoring piezoelectric inductor and operating to obtain a muscle relaxation monitoring data TOF (turnover of frequency) value; and controlling a stepper motor to operate at a specified speed so as to push an injector to administrate medicine at a set speed by using the TOF value as a feedback data base and by a microprocessor by combining a built-in muscle relaxation administration method. The scheme can monitor the muscle relaxation state of a patient in real time, objectively reflect the true iatrical effect condition of the muscle relaxant in the human body and display the TOF value of a muscle relaxation feedback value, and meanwhile, an injection system can automatically administrate the muscle relaxant in the whole course according to the TOF value. Moreover, artificial interventions are not needed, and the automatic administrated dosage and the method are obtained through a large quantity of population parameters. The invention ends the times of fuzzy muscle relaxant administration and can scientifically improve the controllability of the muscle relaxant, avoid medicine deficiency or excess and improve the operation quality.
本发明公开了一种简单易用的闭环肌松药效监测及注射方法和一种闭环肌松注射装置,具体方法是:通过独立研发的肌松监测压电感应器获取病人肌肉肌电反馈动作,运算获得肌松监测数据TOF数值;以此为反馈数据基础,微处理器结合内置的肌松剂给药方法,控制步进电机以指定的速度运转,推动注射器以设置速度进行给药。该方案可实现实时监测病人的肌松状况,客观反映肌松药在人体内真实的药效情况,显示肌松反馈数值TOF值,同时注射系统能根据TOF数值全程自动给进肌松剂,而且,可无须人工干预,其自动给药量及方法经过大量的群体参数得出。本发明结束了模糊肌松给药时代,能科学提高肌松用药的可控性,避免用药不足或过量,提高手术质量。
