Design Of Electronic Blood Pressure Monitoring System Based On Mobile Health Platform

With the development of the whole society and the growing pace of technological innovation, medical standards are needed for higher requirements by human beings. Response to market needs, health care systems become popular. This kind of system is easy to operate, compact and portable, etc, which is widely accepted by the public.In this paper, a kind of non-invasive cuff blood pressure monitoring system based on mobile health platform is designed and presented, including hardware and software implementation,and a ZigBee wireless transmission module in order to send BP data to the Information System in real time.Firstly, introduce the development of mobile health platform briefly and basic knowledge of blood pressure, including blood pressure principle, measuring principle, numerical judgement, etc.Secondly, put forward overall design scheme of the system, and determine system components and corresponding design index.At last, this thesis discusses my main development jobs:The first job is to research causes of the human body blood pressure, blood pressure numerical algorithm and software and hardware circuit analysis. Validity of the circuit proposed is verified through the Multisim simulation software.The second job is to design hardware system, including amplifiers and filters, air pump, electromagnetic valve and ZigBee wireless transmission hardware system. Finally, considering the influence of PCB layout to electromagnetic compatibility.In software design, blood pressure calculation method and data processing are discussed, especially the design of system software, error analysis and the preprocessing,etc.In the end, analyze the corresponding experimental results, verify the reliability and feasibility of blood pressure monitoring system. Make summary and prospect on the results, and develop a plan of improvement and optimization.
