[The development of a pocket blood pressure holter based on handhold personal computer].
This paper introduces a kind of pocket blood pressure holter based on handhold personal computer. The measurement of blood pressure is controlled by ultralow power consumption MCU. The system configures interface circuit with handhold personal computer. The BP data can be stored, displayed, analysed and transmitted by handhold personal computer. The measurement parameters can be modified. The hardware is made up of three units: simulation circuit unit, intelligent control unit and interface circuit unit. Every unit structure and its principle are presented. The software of obtaining the BP data and communication with handhold personal computer are also illuminated. The system possesses the characters of portability, intelligence, convenience, high precision, ultralow power consumption and stable capability. It is possible to become an ideal blood pressure monitor in family.
