    Fabrication and Evaluation of an Affordable Infant Radiant Warmer for Use in Limited Resource Settings
    (Arid Zone Journal of Engineering, Technology and Environment (AZOJETE), 2023) Ibitoye, M. O.,; Ahmed, Y. K.,; Saad, A. B.,; Ajibola, T. M.
    The challenges of thermoregulation due to hypothermia, which is believed to underlie high infant morbidity and mortality rate, is common with underweight or preterm infants especially those from limited resource settings. Available devices in the market to check hypothermia are expensive, especially for most countries with between 2% to 10% of GDP on the healthcare budget. Affordable thermoregulation realization for infants is therefore of significant clinical importance in these settings. The aim of this studywas to design and fabricate an affordable ($110) and clinically useful radiant warmer to facilitate hypothermia treatment. The radiant warmer was fabricated with an overhead radiant heater for heat radiation targeted at infants laid in a clinically comfortable foam mattress in a bassinet. A portable fan was placed above the heating element to facilitate downward heat flow. A biocompatible temperature sensor was also placed on the bassinet to monitor the infant’s body temperature. The warmer incorporated anArduino-based PID temperature microcontroller to regulate the temperature of the heating element. The warmer, with castor wheels to aid the device’s mobility, has a strong and durable galvanized pipe stand capable of supporting the device. The device performance indicated an acceptable physiological heating temperature range of 36 °C -36.5 °C within 20 min of warm-up and up to 36.7 °C in 30 min of use. Therefore, the device can be adjudged potentially useful in facilitating thermoregulation in infants by providing suitable thermal support. With these results and the potential of the device to reduce infant mortality rates and promote their growth, it is hereby recommended that the device may be fully deployed for clinical application

    Non-invasive glucometer using acetone gas sensor for low income earners’ diabetes monitoring
    (2022) Ajibola, T. M.; Ibitoye, M. O.; Ahmed, Y. K.; Jimoh, Z. G.
    A glucometer is an important device used to monitor blood glucose level of diabetes patients to prevent degenerated health conditions. The conventional glucometers are characterized by piercing of the sample site for patients’ testing. The invasive nature of these glucometers is painful to the patients and some patients are also scared at the sight of blood. To promote glucometer acceptance among patients, it is important to develop a non-invasive glucometer using acetone gas sensor with “exhaled breath” collected non-invasively as the sample for the glucometer. After the device development, exhaled breath sample of twenty subjects with age range of 20 to 55 years from a University were taken using the developed acetone sensor device. Prior to the exhaled breath sample collection, the blood glucose levels of the volunteered subjects were also determined using the conventional and proprietary invasive clinical method. To infer whether there is significant different between the mean of the results obtained from the conventional and the exhaled breath method, a t-test was carried out on the results and P values of 0.9860 and 0.9306 were obtained for fasting blood sugar and random blood sugar respectively, indicating no significant differences in the results obtained from the developed device when compared with the proprietary device. Hence, non-invasive glucometer using acetone gas sensor can be used to promote inexpensive personalized diabetes monitoring without inflicting pain on the patients. Promotion of this device could also reduce the expenses incurred on lancet and test strips, thus, making it suitable for low income earners.
