Abstract
The present invention discloses a sphygmomanometer having 3D positioning function, which comprises a microprocessor chip which is coupled individually to a microprocessor chip which is coupled individually to a pressure sensor, an alarm unit, a storing unit, a 3D acceleration sensor chip, a display device, a driving device, and an air valve, so that when a person's blood pressure is measured, the 3D acceleration sensor chip detects the spatial position of the measuring cuff of the sphygmomanometer and sends the parameters related to the detected spatial position to the microprocessor chip. In the meantime, the microprocessor chip will retrieve a predetermined range of the parameters related to the spatial position from the storing unit, and compare such range with the value of the detected parameters. If the values of the detected parameters fall beyond the predetermined range of parameters, the microprocessor chip will issue an alarm through the alarm unit until the spatial position is correct. Thus the person who takes blood pressure measurement can always get the most accurate measurement.
