Abstract
A blood pressure measurement module includes a top cover, a micro pump, a driving circuit board, and a pressure sensor. The top cover has a gas inlet hole, an accommodation trough, and an outlet channel. An inner wall of the accommodation trough is recessed to form a gas collection chamber in communication with the gas inlet hole, and the outlet channel is connected to a gas bag. The pressure sensor is electrically connected to the driving circuit board. The driving circuit board covers the accommodation trough of the top cover. The operation of the micro pump is controlled by the driving circuit board. The gas is continuously guided to the outlet channel and is converged at the gas bag by the micro pump. When the pressure of the gas in the gas bag measured by the pressure sensor reaches a valve value, the micro pump stops its operation.
