Design and Development of a Voice Actuated Hospital Bed for Patient Care

Abstract

In the recent twentieth century, medical beds are subjected to advanced techniques particularly in the domain of making it intelligent for patient care. The past fifteen years have brought out various changes in the smart-bed technologies concept but no legit proof for existence of the project were shown. These and other earlier systems more often utilize at least one pushbutton or pressure-sensitive type switches to enact the different correspondence and control capacities. The proposed aim is to build a prototype bed which can respond to basic commands and helps the user to recline, incline and command for a food table which also monitors the minimum spacing required for the bed to incline or recline using a simple mechanism and therefore, sends a feedback to the system warning about the spacing between them. The voice recognition (VR3) module is used to detect the keywords for the trained voice when the user is passing commands to perform any of the actions such as Inclination, Reclination, Upward, Downward etc. Functions like bedroom necessities, turning on appliances and various other activities can also be carried out as an extended function.
