摘要： The invention features an exhalation assist device for adjusting the airway resistance in an exhalation circuit of a medical ventilator. The device includes a set of pressure, airflow and airway sensors, a controlling processor, a user interface, and a ventilatory unit in communication with a medical ventilator. Data relating to pressure within the ventilatory unit and data relating to exhalation airflow, exhalation circuit pressure and exhalation circuit resistance are provided to the controlling processor by the sensors. The controlling processor compares measured and calculated values for airway pressure, airflow, airway resistance and applied negative pressure with desired values that have been entered by a clinician. Based on these calculations, the controlling processor transmits a signal that will change the applied negative pressure applied to the exhalation circuit by the ventilatory unit. The amount of negative pressure applied during the breathing cycle is varied by the controlling processor so that the amount of exhalation assist increases proportionately with the amount of exhalation flow and so that the amount of pressure within the patient airway remains constant at a level greater that zero and less than PEEP.

摘要翻译：本发明的特征在于用于调节医用呼吸机呼气回路中的气道阻力的呼气辅助装置。该装置包括一组压力，气流和气道传感器，控制处理器，用户界面和与医疗呼吸机通信的通气单元。通过传感器向控制处理器提供与通气单元内的压力有关的数据以及与呼出气流，呼气回路压力和呼气回路电阻有关的数据。控制处理器将气道压力，气流，气道阻力和施加的负压的测量值和计算值与临床医生输入的期望值进行比较。基于这些计算，控制处理器发送将通过通气单元改变施加到呼气回路的施加负压的信号。在呼吸循环期间施加的负压量由控制处理器改变，使得呼气量的辅助量与呼气量成比例地增加，并且使得患者气道内的压力量保持恒定在大于零的水平小于PEEP。
