Abstract: An airbag of an electronic blood pressure monitor is provided. The airbag includes an outer wall and at least one connection wall; the outer wall includes a first wall, a peripheral side wall, and a second wall; the first wall and the second wall are disposed opposite to each other; the peripheral side wall is connected to a periphery of the first wall and a periphery of the second wall; the first wall, the side wall, and the second wall form an air chamber; the at least one connection wall is located in the air chamber; each connection wall is connected to at least two of the peripheral side wall, the first wall, and the second wall; and each connection wall is tensed when the airbag is in an expanded state. This application further provides an electronic blood pressure monitor including the airbag.

Abstract: An electronic device for measuring blood pressure includes a measurement assembly, an airbag, and a fluid pipeline, where a fluid pump and a pressure sensor in the measurement assembly are connected to the airbag through a first fluid pipeline and a second fluid pipeline respectively, a first nozzle in the first fluid pipeline and a second nozzle in the second fluid pipeline are located on a same side of the airbag, and an opening direction of one of the first nozzle and the second nozzle is away from that of the other, so that the first nozzle and the second nozzle are away from each other. This reduces impact on the pressure sensor caused by airflow in the airbag, and improves blood pressure measurement accuracy.
