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.
