    Abstract: An auscultatory sphygmomanometer system includes a pressure sensing and working module and a cuff. The cuff has a tube connected with the pressure sensing and working module, a gasbag connected with the tube and inflated or deflated according to the working state of the pressure sensing and working module, an audio pickup probe disposed on the gasbag and using a lateral surface of the gasbag as an oscillation membrane, and a cuff body accommodating the gasbag. While the cuff body is wound around a testee's arm, the gasbag is positioned into a first surface neighboring the testee's arm and a second surface opposite thereto and far away from the testee's arm. The connection position where the tube is joined to the gasbag is on the second surface. The sounds picked up by the audio pickup probe are sued to determine the systolic pressure and the diastolic pressure.
