1. A blood pressure measurement module, comprising:
a top cover having a gas inlet hole, an accommodation trough, and an outlet channel, wherein the gas inlet hole and the outlet channel are respectively disposed on different surfaces of the top cover, and are respectively in communication with the accommodation trough, wherein an inner wall of the accommodation trough is recessed to form a gas collection chamber in communication with the gas inlet hole, wherein the outlet channel is connected to a gas bag, and wherein the top cover has a side wall portion, and the outlet channel is disposed on the side wall portion;
a micro pump disposed in the accommodation trough to cover the gas collection chamber;
a driving circuit board covering the accommodation trough, wherein the driving circuit board controls operation of the micro pump; and
a pressure sensor fixedly disposed on the driving circuit board and electrically connected to the driving circuit board, wherein the driving circuit board covers the accommodation trough of the top cover so as to detect a pressure of gas guided into the accommodation trough;
wherein the operation of the micro pump is controlled by the driving circuit board for a gas transmission, so that a gas outside the top cover is capable of being guided into the accommodation trough through the gas inlet hole, and the gas being continuously guided to the outlet channel and being converged at the gas bag by the micro pump, wherein the gas bag is configured to inflate and press against skin of a user, and the pressure sensor is configured to measure a blood pressure of the user, and wherein when the pressure of the gas in the gas bag measured by the pressure sensor reaches a valve value, the driving circuit board controls and stops the operation of the micro pump so as to complete a pressure collection process of the gas bag.
