NASAL INTERFACE APPARATUS AND SYSTEMS FOR USE WITH A RESPIRATORY ASSIST DEVICE

An ambulatory assist ventilation (AAV) apparatus and system are disclosed for the delivery of a respiratory gas to assist the spontaneous breathing effort of a patient with a breathing disorder. The AAV system includes a compressed respiratory gas source, a respiratory assist device for controlling respiratory gas flow to the patient, a patient circuit tubing and a low profile nasal interface device, which does not have a dead space or hollow area where C02 can collect, for delivering the respiratory gas to the patient, wherein the nasal interface device is fluidly connected to the respiratory assist device via tubing for receiving the respiratory gas therefrom. In some cases, the nasal interface device may be used in combination with other gas sources, such as oxygen concentrators, to provide dual therapy capability suitable for some applications. 本发明公开了一种用于输送呼吸气体的流动式辅助通气(AAV)装置和系统，以辅助呼吸障碍患者的自主呼吸作用。所述AAV系统包括压缩呼吸气源、用于控制流向患者的呼吸气体的呼吸辅助装置、患者回路管以及用于将呼吸气体输送给患者的低外形的鼻接口装置，该低外形的鼻接口装置不具有可收集CO2的死区或中空区域，其中所述鼻接口装置经由管流体地连
