Abstract

The application relates to a pressure sensing device and a trachea cannula cuff device, which comprises a trachea connecting piece, the trachea connecting piece comprising an inner cavity arranged through along an axial direction thereof; a sensor module connected to the trachea connecting piece, and the sensor module is arranged in communication with the inner cavity so that the sensor module senses a pressure parameter of fluid flowing through the inner cavity; and a first one-way valve directly communicated with one end of the inner cavity, and a flow channel is arranged between the first one-way valve and the inner cavity, the flow channel is configured to inject fluid into the inner cavity in an openable and closable manner, so as to control an injection parameter of the fluid injected into the inner cavity. According to the scheme, the pressure parameter of the fluid flowing through the trachea connecting piece in a diagnosis and treatment process can be sensed and monitored in real time, and convenient installation and application are further realized.
