Patient monitoring system using Wireless Sensor based Mesh Network

Wireless Sensor Networks (WSN) is a significant technology that has a considerable attraction in many areas, particularly in health sector. On the other hand Wireless Mesh Networks (WMN), which are an extension of LAN, have far better range and also reduce the amount of cabling needed to connect to the backbone network. In this paper a scheme that is Wireless Sensor based Mesh Networks, which is an integration of the above two technologies has been used for monitoring the patients status as follows: The patient's temperature, heart beat and pressure is monitored automatically using a bio-medical kit that is connected with the patient. A LCD is provided with the kit that is used to notify the nurse about the patient's health status. The information is then sent to a mesh node through Zigbee technology. The mesh node is generally a PC that helps the duty doctor to monitor all the wards that are present in the hospital. This ensures that the patient's health status is monitored even in the absence of the nurse. From the mesh node, a SMS is sent to specified doctors through GSM connection. With the help of the information got through SMS, the doctors can be able to attend the patient very quickly. Since the monitoring is done automatically there is no need for any person to look after the patient.
