A blood pressure detection device, includes a detection airbag, a pressure sensor provided on the detection airbag, an air pump configured for inflating detection airbag and a solenoid valve or a proportional valve or an exhaust valve for deflating detection airbag. The blood pressure detection device further includes an airbag clamp configured outside the detection airbag for clamping the inflated detection airbag on the finger, wrist, or arm of the human body. The present invention eliminates the operation of wrapping the airbag on the arm or the wrist in the traditional blood pressure detection, so that the blood pressure detection is more convenient. In addition, the present invention incorporates an airbag into the device of the present invention, so as to avoid separation of the airbag from the detection device body, thereby facilitating the combination of the present invention with household or sanitary products.
