Mechanical ventilation is crucial for patients with severe respiratory distress. While single piston-actuated ventilation is popular, this study presents an electro-pneumatic assessment of airflow in a coupled-double-acting piston ventilator (DPDACV) using simulation results from FluidSIM. The DPDACV design aims to leverage a dual-piston mechanism for enhanced stability and performance in tidal volume delivery. Simulations conducted over 2, 10, 30, and 60 seconds revealed that the DPDACV provides more consistent volume delivery, stable flow rates, and relatively higher, more stable pressure levels compared to single-piston systems. These findings suggest that the DPDACV can offer improved ventilation efficiency and patient safety, contributing valuable insights to the field of mechanical ventilation. © 2024 IEEE.
A Smart Medication Dispenser for Enhanced Elderly Care
(Nigerian Institution of Professional Engineers and Scientists, 2025) Ugo, H.C.; Akinbiola, A.; Ozoemena, S.; Oyejide, A.J.; Isaac, E.G.
The aging population and prevalence of chronic diseases present significant challenges in medication adherence, especially in resource-limited settings where healthcare resources are scarce. This study aimed to develop a cost-effective smart medication dispenser tailored to the needs of elderly patients in these settings. The device integrates pill and syrup dispensing capabilities, featuring audible alarms, hand-sensor technology, and a communication module for notifications to caregivers and healthcare providers. The dispenser was evaluated through a series of trials to assess its accuracy in dispensing pills and syrups and the performance of its notification and alarm systems. The device achieved high accuracy in pill and syrup dispensation. Notification alerts were timely, with delays ranging from 3 to 10 seconds, and the buzzer system showed consistent performance with an average delay of 1.5 seconds. The smart medication dispenser stands as a promising tool for enhancing medication adherence and ensuring the safety and health of elderly individuals. Its affordability and ease of use make it particularly suitable for resource-limited settings, offering a reliable solution to improve health outcomes and reduce the burden on healthcare systems. © 2025 NIPES Pub.
