【正文】 a Zigbee [1] work there are several more advantages including, cable replacement, mobility and location management. Once these devices are worked they can also use the infrastructure of other deployments of similar wireless sensor works in the surrounding environment. To achieve this type of solution each device must be fitted with a piece of hardware that will act as a serial to wireless bridge, a Medical Device Interface (MDI). This MDI will allow the device to receive and transmit data within the wireless sensor work. This inexpensive hardware will be generic to fit a wide range of medical devices. Similarly the firmware can be kept generic and any specific device munication protocols can be implemented on a server on the work backend. The work described in this paper is part of a larger project, the goal of which is to provide a plete patient monitoring system. Other features of the overall system will be to provide ECG (Electrocardiogram) and PulseOximetry data in a novel way over a wireless sensor work using expertise gained on prior projects [2]. RELATED WORK The concept of using wireless sensor works for Medical Care and wireless patient monitoring has been explored by others but integrating data from other devices is generally not discussed. There is ongoing related work in patient monitoring using wireless sensors such as the “CodeBlue” project at Harvard [3]. Others have also proven successful with wireless sensor works designs for medical sensors [4] and in the management of sensor data [5]. It has been identified that it is desirable to wirelessly enable existing medical devices that provide vital signs data using technologies such as Zigbee [6], [7]. The research described in this paper aspires to meet these requirements. The use of wireless sensor works within the hospital has been extensively examined. Moreover, other wireless technologies within the same frequency band, such as IEEE [8], have existed within the hospital for some time [9]. III. REQUIREMENTS ANALYSIS Wireless Technologies Established standards for wireless applications, such as Bluetooth [10] and IEEE , allow high transmission rates, but at the expense of power consumption, application plexity, and cost. Zigbee offers low cost, low power devices that can municate with each other and the outside world.

This is particularly useful in a hospital environment where interference from walls, people and general obstacles is a major issue.
