ABSTRACT:
An LED display blood pressure meter comprising a transmitter, a receiver, a sensor, an amplifying circuit, a transferring circuit, a microprocessor and three display circuits. When measuring human blood pressure, the blood pressure values are sensed and transferred into electronic analog signals by the sensor. The analog signals are amplified by the amplifying circuit and transferred into digital signals by the transferring circuit. The digital signal is then received and processed by the microprocessor which drives the display circuits to display the ascending/descending of the blood pressure values by means of LED array and show the high and low blood pressure values in digital pattern by means of LED displays. The high and low blood pressure values are latched by means of a transmitter and a receiver in remotely controlling manner so as to be stably displayed in a display panel.
