Real-time feedback-centric nurse calling system with archive monitoring using Raspberry Pi

The relationship between nurse and patient is vital as well as vulnerable on which a significant portion of well-being of patient depends. The recent growth of Internet of Things provides the opportunity to maintain this relationship in a more secure and efficient way. From this point of view, this paper presents a system of real-time nurse calling with focus centered on nurse feedback based on patient condition. The system also includes a robust archive monitoring system for review and trend analysis. In the proposed system, patients are able to call for assistance in time of emergency by pressing a designated button. After this, the device will send a real-time message containing information about the patients bed, room, and floor number to the appropriate nurse station. Nurse will respond as soon as the message is delivered, and optionally call for help by pressing designated buttons in the device. The proposed system reduces the delay in response of nurse. Additionally, the interactions are stored in Raspberry Pi database for future analysis to improve the quality of services. The proposed system uses low-cost hardware like ATMEGA328P microcontroller and ENC28J60 Ethernet controller, and Arduino Uno.
