Developed Based On The Arm Remote Home Monitoring Intelligent Terminal System

With the continuous improvement of living standards, there is a growing emphasis on people's health care and wellness checks. Whilst with the increasingly aging of the population, health of the elderly has become the subject of the social concerns. But in the current medical system, most hospitals can't meet the needs of the community because they are interested in the treatment of the diseases. Also some diseases have no obvious symptoms, but suddenly are taken bad at home. Due to lack of timely medical treatment, people's illnesses became worse or even die. So development of a new medical model is absolutely necessary. A new home health telemonitoring system based on community is the right way to solve these problems. In the system, the family is the core and patients at home can enjoy the professional care like in hospital.This paper developed a new home health telemonitoring system based on community and family. The structure of the system is "Home — Community Hospital -- Main hospital". The system includes an intelligent terminal at home-side and a viewer system for the therapist at community hospital. In this paper, the design of the home-side intelligent terminal system's hardware and software is the key.This paper presents the scheme of the intelligent terminal hardware and software system in the new home health telemonitoring. The Philips LPC2214 is the core of the intelligent terminal's hardware platform, which is 32-bit ARM kernel embedded microprocessor, Periphery expands Bluetooth module, ISP1160 USB Host Module, 10M Ethernet communication module, CF card memory module and LCD modules. This paper minutely depicts the design of the hardware module. Based on the hardware platform, we transplant the embedded operating system μC/OS- II. According to software architecture, which has operating system, Middleware and application procedures three layers, we design and implement the home-side intelligent terminal's software. So that the software of the intelligent terminal easier to maintain and upgrade.In this paper we state the realization of the intelligent terminal software in detail. We design the driver of the hardware modules, communication protocols and applications. The entire application process is divided into nine functional tasks scheduling by the operating system kernel. So the reliability and real-time of the system has improved. A user-friendly interface and automatic physiological signal analysis program are important parts of the application programs. The automatic analysis and diagnostic of ECG signals are studied. Applying the adaptive template automatic diagnostic algorithm, the home-side intelligent terminal is able to automatically analyze and diagnose 10 kinds of common abnormal rhythm.The intelligent terminal system can timely collect and transmit multiply physiological parameters, such as ECG, NIBP, blood glucose, body temperature, respiratory rate and oxygen saturation. And monitoring parameters can be customized according to the patient's condition, which make the home health telemonitoring system to be good scalability and flexibility. The intelligent terminal system can collect ECG and the body temperature through Bluetooth wireless module and acquire other physiological parameters such as blood pressure parameters using the other modules, which connect to USB Host down-link. The acquisition parameters are analyzed by the terminal. Then the physiological parameters and results can display on the LCD (liquid crystal display), and also be sent to telemonitoring center's server through LAN. In the community hospitals the therapist could use the physiological parameters to analyze and diagnose. When physiological abnormalities emerge, the intelligent terminal can give a preliminary diagnosis and alarm to patient and therapist. Seeing the alert, the therapist should give a diagnostic results based on the patient's physiological parameters immediately. The diagnostic results will be transmitted back to the home-side intelligent terminal and be displayed on LCD. So patients can receive timely treatment.The subject has developed an intelligent terminal home health telemonitoring system, which has a simple and friendly interface, high scalability and flexibility, can achieve low-cost and real-time telemonitoring. In addition, using embedded system design, the system has high real-time and reliability. Through testing, the intelligent terminal system achieves the desired design requirements of the home telehealth and has high practical value.
