Wireless Patient Monitoring System using Zigbee

As we have renowned hospitals all over the world, but still there is a need of better health care monitoring system. The ratio of staff in the hospitals is less than the total number of patients; also a paramedical assistant need to continuously monitor and note down all the vital parameters of a given patient by keeping track of all of his/her records manually. Adopting such a method is error prone and may lead to disaster in the case of a human error.In the current proposed system a better solution to raise the standard of existing continuous patient health monitoring system is given. Continuous patient monitoring needs frequent measurement of the associated health parameters status. The wireless Technology used here is Zigbee. A ZigBee node is connected to every patient monitor system that consumes very low power and is extremely small in size. These are specifically designed for low power consumption, with minimal circuit components intended for small packet, long distance range applications .Sensors are used to monitor the patient continuously over long period of time until the abnormal condition is detected. Once detected, the collected data is sent securely via Zigbee to the physician taking care of that particular patient for further analysis. If a mismatch occurs, a buzzer alarm is issued and the results will be displayed on LCD and Laptop display. Hence, the main goal is to alert hospital staff in case of emergency during abnormal conditions.
