增量式PID控制算法和HMI-3084实际系统控制条件下智能呼吸椅的研制与开发

Development of an intelligent respiration and sanitarian chair based on HMI-3084 and incremental PID algorithm

背景:目前正压通气技术广泛应用于呼吸衰竭等肺部疾病的治疗,但由于正压通气也存在着诸如呼吸机相关肺炎、低血压和撤机困难等弊病,使得该技术在实现呼吸维持功能的同时也给患者带来了更严重的生命威胁。目的:探索一种新产品,能够实现肺部疾病治疗的安全性和智能性。方法:结合传统摇椅和变换体位机械通气方法,利用增量式PID控制算法,同时借助威控HMI-3084实际系统控制,创新性地提出了基于HMI-3084的智能呼吸保健椅。结果与结论:该设备不仅具有传统摇椅功能,还具有辅助呼吸功效,能实现指令控制通气和呼吸同步辅助通气,主要是针对慢性阻塞性肺炎患者的康复治疗,可能成为新一代的医疗保健设备。

BACKGROUND： Nowadays positive pressure ventilation has been widely applied in breath prostrating and other diseases of lung. But its disadvantages, such as pneumonia relating to breathing machine, abnormally low blood pressure and difficulty in removing breathing machine, bring risks for patients while supplying breathing function. OBJECTIVE： To develop a new product to cure the disease of lung safely and intelligently. METHODS： Combined traditional rocking chair and the way of mechanical ventilation through changing posture, intelligent sanitarian chair based on HMI-3084 was designed innovatively using control algorithm of incremental PID. RESULTS AND CONCLUSION： This equipment has the function of traditional rocking chair and effect of auxiliary respiration. It can realize controlling mechanical ventilation and auxiliary ventilation through respiring synchronously. It aims at the chronic obstructive pneumonia and may become a new medical sanitarian facility.
