Wrist sphygmomanometer

The utility model relates to the technical field of blood pressure measurement, in particular to a wrist type sphygmomanometer which is high in measurement accuracy and easy to operate and comprises a sphygmomanometer body which comprises a control unit, a blood pressure measurement module and a power supply unit and further comprises a gravity acceleration sensor connected with the control unit and used for judging the ground direction. And a plurality of TOF sensors for detecting the height to the ground. According to the wrist sphygmomanometer, the gravitational acceleration sensor and the TOF sensor are arranged in the sphygmomanometer body, and after the gravitational acceleration sensor judges the ground orientation and the TOF sensor detects the ground height, correction data for calculating the blood pressure value are provided for the sphygmomanometer body, so that when a user measures the blood pressure, even if the user freely moves and changes postures, the blood pressure can be accurately measure
