ABSTRACT: The main aim of the project is to implement a low cost reliable system which will help to establish
communication between paralytic or disabled patients and a nurse. A patient can easily send messages to the nurse by
just tilting an accelerometer connected to a body part capable of movement. This angle of tilt is sent to a central
controller which then initiates communication between the patient (transmitter) and nurse (receiver) and also decides
which message is to be transmitted based on the tilt angle. Each patient will have such a device installed on or around
his body and all such patients will be centrally linked to the receiver at the nurse side. Along with this a real time
medicine reminder and an emergency buzzer to simplify the work of the nurse was implemented. Our project provides
a reliable, effective and simple yet important solution to various issues faced by nurses in traditionally communicating
with disabled patients.
We come across hospitals and NGO’s serving disabled people. Now these people are not capable of full body movement as compared to a normal person. In such a situation we propose a system that helps disabled person display a message by just simple motion of any part of his body. Our proposed system works by reading the tilt direction of the user part. This device needs to be mounted on user finger of hand. The user now just needs to tilt the device in a particular angle to convey a message. Tilting the device in different directions conveys a different message. Here we use accelerometer in order to measure the statistics of motion. It then passes on this data to the microcontroller. The microcontroller processes the data and displays the particular message as per input obtained. The microcontroller now displays the associated message on the LCD screen. It also sounds a buzzer along with message as soon as it receives motion signal from the accelerometer. The patient motion recorder device consists of an RF transmitter in order to transfer the data signal. An RF receiver on the other side receives the data and then decodes it before passing it to the microcontroller for processing the input and responding to it.
