Abstract
A respiratory device includes a host, a pressure sensor and a connecting module. The host includes a first airflow channel and a first shell. The first shell includes a communication part running through the first shell. The pressure sensor is installed in the host and connected with the communication part. The connecting module includes a second airflow channel, a filter and an airflow guiding part. The second airflow channel is in communication with the first airflow channel. The filter is used for filtering an airflow from a breathing tube. A first end of the airflow guiding part is in communication with the communication part, and the unfiltered airflow is introduced into a second end of the airflow guiding part. A pressure level of the unfiltered airflow is detected by the pressure sensor through the communication part and the airflow guiding part.
