Design And Implementation Of CPAP Ventilator Telemedicine System

In the 13th Five-year Plan,it put forward 100 major projects China plans to implement.Among them,the development of nuclear medical imaging equipment,superconducting magnetic resonance imaging system,non-invasive ventilator and other high-performance medical equipment ranked No.31.Non-invasive ventilator,also known as Continuous Positive Airway Pressure ventilator(CPAP ventilator),is a very safe and effective way to treat Obstructive Sleep Apnea Hypopnea Syndrome(OSAHS).In recent years,it has played a significant role in modern clinical care.At present,in response to the call of the national strategy,the ventilator industry has developed rapidly.CPAP ventilator is not limited to be used in hospitals.Many manufacturers launched CPAP home ventilator for home environment applications,which was more safe and convenient.However,it is also faced with a new problem of how to let the doctor have better monitoring to the patients,breathing conditions in a timely manner.With the rapid development of information technology,the wireless or wired network communication technology has combined CPAP ventilator with remote medical system.In this way,the patient's physiological characteristics can get real-time detection and doctors will find problems and adjust treatment program timely.In view of this,this paper provides a design for CPAP ventilator remote medical system.In this paper,CPAP ventilator telemedicine system is mainly composed of three major parts,namely,information storage,information management and telemedicine.The first two parts of the system are to complete the design of medical terminals and the third part focuses on the realization of remote information interaction between doctors and patients.The information storage module of the system refers to that after logging in to the local medical terminal with the user right,the system communicates with the CPAP ventilator through the RS485,collects and analyzes the breathing parameter information in real time according to the prescribed data communication protocol.Then it uses the incremental data compression mechanism to save historical data in the form of serialized binary files and transfers it to remote medical terminal in response to the data access requests.Meanwhile,the module provides data analysis and image drawing capabilities with ProEssentials industrial drawing control,which are reflected in the medical interface design.The information management module of the system includes the permissions set when logging into the system,users' information management after log into thesystem and electronic medical records report output and other aspects.Among them,the login permission settings is achieved through the user authentication mechanism.Users' information management is the management of user's basic information and respiratory information after doctor's logging into the remote medical terminal,which are achieved by using FastDB database.In addition,based on electronic medical record technology,the module also added a case report output function which is easy to view and analysis.The remote medical module of the system is designed to provide telemedicine services through network connection between the local medical terminal and the remote medical terminal.Among them,remote communication makes wired or GPRS wireless network connection based on TCP/IP protocol.In order to complete the remote monitoring and remote control functions,it achieve remote data interaction supplemented by asynchronous socket technology and multithreading technology.In this process,the remote medical terminal monitors the remote alarm messages in real time,processes it and generates alarm prompt and SMS push to realize intelligent alarm function.Finally,through the complete testing of CPAP ventilator telemedicine system designed in this paper,including functional test and performance analysis,it is proved that the design scheme is effective and feasible.It can achieve the desired goal and has good practical application value.In addition,based on the results of this study,this paper also put forward several aspects of the system to be further improved in the future.
