Product characteristics: LED bargraph sphysphygmomanometer is a next generation product replacing the mercury mercury column) sphygmomanometer. It has thoroughly removed the environmental pollution caused by the mercury in the mercury (mercury column) sphygmomanometer as well as the mercury harm and treatment problems. Therefore, it's new, green, environment-friendly, practical and toelectrical hi-tech medical device.
Product working principle: The mercury (mercury column)sphygmomanometer follows the hydrostatic equilibrium principle for working. A connector is used to connect is used to connect the mercury storage bottle to the value indicating tube. When the mercury in the mercury stirage bottle is pressed on the surface, the mercury inside the value indicating tube will be forced to rise to indicate the pressure value. However, LED bargraph sphygmomanometer follows the working principle of the pressure sensor for its working. When the pressure sensor is pressed, the control circuit will drive the grating stripes, thusindicating the pressure value.
Measuring method: The measuring method of LED bargraph sphygmomanometer conforms to the principle of Korotkoff's Sounds (stethoscopy and actual measurement) recognized by the international medical community.
Operating method: The operating method is the same as that of the mercury sphygmomanometer without changing any use habits and operating modes of the user except it is provided with 3 additional AA environment-friendly alkali zinc-manganese dioxide batteries.
