2-D Motion based Real Time Wireless Interaction System for Disabled Patients

With the increasing number of disabled patients in hospital, diversified needs of patients at certain times are to be fulfilled. To provide with eminent healthcare and service, a full time caretaker or 24 hour monitoring system may be needed, requiring a huge amount of manpower and cost. In this paper a low cost real time implementable system in hospital to establish communication between multiple patients and nurse is proposed. A small wireless transmitter consisting of Arduino Nano, NRF 24L01 and Accelerometer ADXL 335 is attached to a movable body part of the patient working as message (8 messages) conveyer. Device of every patient will be centrally linked to the receiver point at nurse's end by wireless medium using SPI transmission. The central receiver can convey the message from all patients in a screen and trigger and alarm for notifying new message. In case of distant wards from the central receiver (>40 m), repeaters are used to convey the message to the central receiver. Via this system the issue of 24 hour monitoring can be solved with a very affordable cost and less manpower, improving healthcare facilities and patient satisfaction in hospitals to manifold.
