Design And Implementation Of Embedded Data Acquisition System Based On ACoral

Plasma apheresis machine rapid development in recent years, It is a medical equipment, apheresis plasma is collected blood plasma components( using peristaltic pump technology from pollution to pump blood, the use of high-speed rotation of centrifuges in the blood plasma component separation technology), while the remaining components of the human body is also transferred back to the human body, the collected plasma is used in the clinical treatment of a variety of diseases. The plasma collected in the clinic for the treatment of various diseases. This way to collect plasma, can effectively improve the utilization of donor blood, reduce blood costs. This acquisition mode is a new trend of development stage blood banks, hospitals, blood banks, medical institutions and medical device manufacturers are increasingly involved in the field.Plasma apheresis machine is the most advanced medical equipment, It is a Class III medical devices( it can be used to sustain life, means can be implanted in the human body, the human body has a potential danger to human life, safety, life effectiveness of medical devices must be strictly controlled). Based on the stringent requirements of Class III medical devices and must be strictly avoided, directly or indirectly harm the human body. Must be accurate in all aspects under the precise control of the computer running, the maximum to avoid the error occurred. The intelligent, professional plasma apheresis machine is designed to target; safe, reliable and stable criteria apheresis machine is designed; respect, comfort, care, convenience is the apheresis machine design concept. The present stage of plasma apheresis machine mainly rely on foreign imports, domestic plasma apheresis machine R & D and production is still relatively small, in order to improve this situation, the paper-based standards in reference to foreign apheresis machine and the specific circumstances of the country, the design and implementation of a aCoral plasma-based embedded intelligent apheresis machine. This article details are as follows.This paper analyzes the introduction section of the introduction of plasma apheresis machine necessity and research status at home and abroad at the present stage of this stage; then in the second chapter of the main technical background plasma apheresis machine for analysis, including plasma apheresis machine references of normative standards, PCS2 plasma apheresis machine technical standards, system design goals and objectives related to the name terms, the main technical features for user groups, system components and design principles for detailed analysis. And then in the third chapter of the plasma apheresis machine system works are introduced, and a detailed analysis of the various parts of the key technologies in plasma apheresis machine and plasma apheresis machine design focus and difficult, and in the last section of a single plasma mining machine used by the operating system aCoral briefly. Then in the fourth chapter of plasma apheresis machine design requirements for overall and detailed analysis of the system consists of various modules, each module should work completed, the system data flow diagram and operating state diagram, where a detailed analysis of the core logical menus and plasma modules each module ARM system collects traffic. Be analyzed in the fifth chapter of the underlying system design-driven model, division of tasks and so on. Then in the sixth chapter of the system to achieve the communication model, task thread thread synchronization relationship and task design, system status and other content for detailed analysis and description, including the main code of each module. Finally, the practical application and testing of plasma apheresis machine briefly.
