Abstract
The invention relates to a double-mode electronic sphygmomanometer measuring system, which is characterized in that the double-mode electronic sphygmomanometer measuring system includes a Korotkoff sound detection circuit and a Korotkoff sensor which detects the Korotkoff sound on a brachial artery above a human body elbow, and transmits the Korotkoff sound to the Korotkoff sound detection circuit via a cable. The Korotkoff sound detection circuit transmits the amplified and filtered Korotkoff sound signal to a processing unit. The processing unit records, processes and judges the Korotkoff sound. A light-emitting unit is controlled to transmit light-emitting blink display ynchronous to the Korotkoff sound of a testee according to the diagnostic medicine requirements. When the Korotkoff sound appears, the light-emitting unit blinks for the first time. When the Korotkoff sound changes, the light-emitting unit blinks for the last time. When the light-emitting unit blinks for the first time with rhythm the display unit displays a reference systolic pressure, and when the light-emitting unit blinks for the last time the display unit displays a reference diastolic blood pressure.
