Innovative Nurse call System For Patients in Healthcare Centres

Nurses response time to patients call has not been the best as a result of the stress and manual nursing call systems available in many hospitals. This situation has caused a lot of dissatisfaction among patients admitted. This study seeks to provide an improvement on already existing nurse call systems. Despite the existence of nurse call systems that make use of audible signal, nurses still need to manually search for patients who called for their assistance. Hence, this study designed and implemented an automatic nurse call system that uses an audiovisual signal to assist nurses find the location of the patient and reason for admission. An experimental approach was adopted while an electronic device based on Arduino board was designed and constructed. The system operates on 5VDC and can be powered with a DC source operating within the range of 9-32V. To test the communication efficiency of the design, systems data were recorded on system's response time. The average response time of 0.24 seconds was obtained with 15 sampled inputs.
