Abstract:
1. A method for automatically calibrating electronic sphygmomanometer, said sphygmomanometer including a normally used pressure sensor set and at least second and third additional sensors, comprising the steps of: turning on a power supply; setting a control module coupled to a power module at an operating mode; said control module controlling an air pump module to pressurize an electronic sphygmomanometer to a predetermined pressure value; opening a valve of a used pressure sensor set in said electronic sphygmomanometer and also opening a valve of another pressure sensor set at the same time, said pressure sensors being capable of detecting a change of pressure, converting said change of pressure into a numeric value, and sending said numeric value to a processor of said control module, said control module sending said predetermined pressure value and a detected pressure value of each pressure sensor of said pressure sensor set to a display module; and said control module comparing the received numeric values, thereby comparing an air pressure value of said used pressure sensor set with an air pressure value of said second pressure sensor; wherein:
