Abstract: A device for measuring blood pressure receives a vibration signal from a vibration sensor which is used to measure a target area. The device then converts the vibration signal into a digital signal and performs a filtering process on the digital signal. The filtering process involves removing noise around the principal component wave that corresponds to the pulsation of the target area within a specific range in the digital signal. Subsequently, based on the digital signal that has been filtered, the device determines a systolic pressure determination time point and a diastolic pressure determination time point to generate a blood pressure measurement result.

Abstract: A flexible measuring element for use with plural blood pressure measuring cuffs is provided. The flexible measuring element includes a flexible body, an identification block distribution region, and an indicating part. The identification block distribution region is disposed on the flexible body. The identification block distribution region includes at least two different identification blocks matching corresponding identification signs of the plural blood pressure measuring cuffs. When the flexible body is wrapped around an animal limb by a user, the indicating part lies within a specified identification block of the at least two identification blocks for prompting the user to select a specified blood pressure measuring cuff corresponding to the specified identification block.
