A pulse pressure conducting structure comprises a housing and a pulse pressure transmission member, the pulse pressure transmission member joining with the housing to form a cavity for inflation, and at least a part of the pulse pressure transmitting member can, during inflation, directly or indirectly act on a body part to be measured of a subject to be detected. The pulse pressure transmitting member of such structure does not need to be wrapped around a limb, and the parts of the body at which it can be used are not limited. A portable blood pressure detection module and a smart wearable device are also disclosed.
