Continuous positive airway pressure device

Continuous positive airway pressure (CPAP) devices (100) are provided. The device (100) comprises a stabilizing unit (102), a first gas source unit (104), and a patient interface unit (106). The firstgas source unit (104) provides an input gas having a variable flow rate through an inlet port (108) of the stabilizing unit (102). Pressure stabilizer (110) of the stabilizing unit (102) receives theinput airflow, expands and contracts to absorb variations in pressure and provides a continuous airflow at a controlled pressure. Flow meter (112) generates a regulated output airflow based on a preset flow rate. Output airflow is discharged through an outlet port (118) of the stabilizing unit (102) to the patient interface unit (106), which comprises a nasal cannula (120) to provide airflow to apatient and a valve (122) to maintain a positive pressure. 提供了一种持续气道正压(CPAP)装置(100)。该装置(100)包括稳定单元(102)、第一气源单元(104)以及患者接口单元(106)。第一气源单元(104)通过稳定单元(102)的入口端口(108)提供具有可变的流量的输入气体。稳定单元(102)的压力稳定器(110)接收输入气流，该压力稳定器(110)膨胀和收缩以吸收压力变化
