Sensor Network for Monitoring Physiological Signals of Multiple Patients Using can Bus.

The project makes use of CAN technology to sense and transfer the physiological signals and parameters of a patient’s body. With the help of the project, efficient medical services can be provided to the patient in appropriate time. A microcontroller board is used for analysing the signals from patient’s body. If any abnormal value is sensed, the monitoring system gives intimation by raising alarm on the receiver side which are generally in doctor’s cabin or monitoring room. All the process parameters will be seen at the hyper terminal window on the computer on receiver’s side. This project is designed to monitor pulse rate and body temperature of a patient’s body and has been designed considering two patients. It can be achieved using CAN technology. At present this kind of high speed and continuous patient monitoring system has not been implemented Currently, the continuous manual monitoring is done which consumes lot of time and also increases the skilled manpower. This project shall cover the flaws of speed and interfacing problems of the existing system. This increases the efficiency of hospital staffs and improves the comfort of patients and makes monitoring easier. Another most important point is that system makes sure the parameters of different patients do not get mixed up and are sent by the right name of the patient and recorded accordingly as well, only if needed. For providing high transmission speeds, this project has been designed as a system that uses CAN protocol which has a high data rate of 1 Megabyte per second at 1 Megahertz frequency.
