The present invention discloses an auxiliary device for blood pressure measurement, including an audio collection part, an image collection part, and a terminal device. The present invention further provides blood pressure measuring equipment. In the auxiliary device for blood pressure measurement in the present invention, the image collection part records a screen output of an electronic sphygmomanometer or a pressure value corresponding to a mercury column on a mercury column sphygmomanometer by taking a video or a picture, so as to obtain a pressure image signal, and the audio collection part obtains a pulse sound of an upper arm, so that blood pressure can be determined by using an auscultatory method according to the recorded pressure value and the sound. Compared with the prior art, the present invention improves the precision and convenience of blood pressure measurement, so that a vast majority of patients can independently measure blood pressure and obtain an accurate measurement result.
