Enhanced pulse taking device with protection function

The invention provides an enhanced pulse taking device with a protection function, the enhanced pulse taking device comprises a rigid chamber and a pressure sensor, the rigid chamber is internally provided with an accommodating cavity, the accommodating cavity is internally provided with filling liquid for filling the rigid chamber, the middle part of the bottom end of the rigid chamber is provided with a pulse taking detection hole communicated with the accommodating cavity, and the pressure sensor is arranged in the accommodating cavity. A flexible film for sealing the pulse-taking detection hole is arranged at the pulse-taking detection hole; and a pressure sensor is mounted at the top of the inner cavity wall of the accommodating cavity in the rigid cavity. When the device is used, pulse beat directly acts on the flexible film of the pulse taking detection hole in the middle area of the bottom of the rigid cavity, vibration convergence is facilitated, the flexible film generates large-amplitude vibration,
