Wireless Tele Care System for Intensive Care Unit of Hospitals Using Bluetooth and Embedded Technology

摘要

The often found problem in the Intensive Care Unit (ICU) of Hospitals is that the physician is unable to be there all the time with patient monitoring equipment to monitor individual patient`s biomedical parameters. Also, the nurses in charge of ICU have to be on constant move from patient to patient to monitor the vital parameters. This study proposes a wireless telecare system for the patients at the Intensive Care Unit and the proposed system requires virtually miniscule help from the aiding staff. The primary aim of this study is to establish real time bidirectional communication between the patient, doctor and the nurses` base station in an ICU. Biomedical data such as ECG, heart rate , temperature, drip level, blood pressure of the patient are transmitted to the physician`s cabin and nurses` base station using Bluetooth and ARM Technology. Based on the report received, the doctor may prescribe the needed medication for the patient and send it to the nurse base station. The whole system has been implemented and tested. The results obtained are encouraging. The wireless link has been appropriately chosen after careful analysis and study since Bluetooth poses no threat to the patient as such.
