Wireless Patient Database Updating and Tracking System
Patient updating using wireless technologies has been considered for improving the quality of healthcare to increase number of patients, For such patients, comprehensive & reliable wireless patient monitoring system should be designed that can operate autonomously. In this paper, we propose that patient updating should involve transmission of vital signs. In simple terms it updates,tracks the patient information to the doctor’s PC and incase of emergency a voice call is made to the ambulance automatically. To enhance the quality of patient updating. We present a reliable wireless architecture and propose that context-awareness should be utilized.
The rapid development of information and telecommunication technology has brought new revolutions in our everyday lives. The impact to medical field is being felt with many new applications using these new technologies. Telemedicine is very essentially the use of both information technology and telecommunications to provide health services or support health service provision over a distance. Telemedicine systems can be divided into two fields: one is that the mobile devices are used by patients to measure the medical data of them. For e.g., the European EPIMEDICS project has developed a Personal ECG Monitor having the capabilities of recording ECG at anywhere & anytime.
A Peak flow monitoring system via a mobile phone for asthma is developed in UK. The other field is that the mobile devices are used by medical staffs as an assistant for their daily work. A paramedical system has been developed to get efficient medical information in India During the past .decade, several new kinds of mobile devices, such as mobile phones & some intelligent and wearable medical devices have been designed. Combined to the recent proliferation of wireless communication solutions, this provides new development opportunities for telemedicine.However, there are some inherent limitations of mobile devices, such as memory capacity, CPU speed, small screen area, etc.These make internet access from mobile devices more difficult as compared to that from desktop computers.This paper presents a Wireless Patient Updating and tracking system. By using a pc the signals are constantly updated. The main function of the system, i.e., transferring the waveform data and text data of patients to the doctor's PC, has been successfullyaccomplished as well as other auxiliary functions. If the measured parameter is more critical the system will automatically calls the ambulance.
Earlier Radio Frequency is used for this type of communication. But it has the disadvantage that it is used for short distance only. So the system is implemented only inside the hospital.
Sometimes the hospital atmosphere makes the patient calm less. Hence we are implementing our paper in GSM.It serves for long distance and also there is not necessity to implement separate transceivers.
Global System for Mobile communication is a digital mobile telephony system that is widely used in Europe and other parts of the world.GSM is the most widely used of the three digital wireless telephony technologies. GSM digitizes and compresses data, then sends it down a channel with two other streams of user data,each in its own time slot. It operates at either the 900 MHz or 1800 MHz frequency band. GSM networks operate in a number of different frequency ranges. Most 2G GSM networks operate in the 900 MHz or 1800 MHz bands. Some countries in the Americas(including Canada and the United States) use the 850 MHz and 1900 MHz bands because the 900 and 1800 MHz frequency bands were already allocated. Most 3G GSM networks in Europe operate in the 2100 MHz frequency band.
