Abstract
False positive and false negative results are one of the prime reasons for wrong treatment in Bangladesh. This mainly occurs due to the lack of an accurate antibody test setup. Accurate test setups like Elisa (Enzyme-linked Immunosorbent Assay) are very costly, hence the majority of the population cannot afford them. So, the aim of this project is to build a low-cost Elisa reader for low resource settings which will be affordable to the entire population. The device works based on a local led diode light, sensor and an Arduino. We have conducted a clinical evaluation over 152 human HBsAg samples with an accuracy of 95.39%, sensitivity of 93.33% and specificity of 97.40% for the proof of concept.

Farihin Rahman, Sayeed Sajjad Razin, S.m. Sakeef Sani
Supervisor: Shams Nafisa Ali, Lecturer.
Abstract
In this project, we propose a novel noninvasive, affordable, passive, semi-automated fetal heart rate monitoring device and its accompanying methodology to provide continuous fetal heart rate (FHR) tracing indicating fetal heart rate variability, acceleration, deceleration, tachycardia or possible abnormalities and overall fetal wellbeing. The approach is based on fetal heart sound. The method consists of a step-by-step procedure to find the best location for acquiring fetal heart sound using a biocompatible belt and the calculation of confidence factor. A real-time signal processing algorithm is proposed to calculate the instantaneous fetal heart rate from the acquired sound. The device was tested at a local hospital and our results were compared with the Cardiotochography (CTG) tracings.

Abstract
Rapid fall in pulse pressure is a critical state for dengue patients who are going through the Dengue Shock Syndrome (DSS). Continuous monitoring of patient’s physiological parameters relevant to DSS and an user friendly alarming system can save patient’s lives and reduce death rate in dengue. But the increasing number of dengue patients along with the lack of resources results in poor patient management and lack of monitoring of critical patients. In order to address these issues, we developed a device with special sensor that can monitor all the vitals of a dengue patient in real-time. The system embedded in the device continuously processes data to detect critical-state entering patient and sends real-time data with push notification to the connected mobile device of the medical personnel in charge. We developed a flutter-based mobile app that shows the critical conditions of the patient connected to the device along with necessary identifications to locate the patient. These features help with prioritizing responses that would allow medical care givers to find critical patients faster in emergency situations and take appropriate action. Overall this study aims to enhance healthcare access and management for dengue cases, resulting in much improved patient outcomes as well as shorter response time via seamless integration of sensor technology with an easy-to-use mobile app.
View-Retina: Low-cost Smartphone Ophthalmoscope
Tahia Ifreet, Abrar Ahmed, Moidul Hasan
Supervisor: Shams Nafisa Ali, Lecturer.
Abstract
Retinal abnormalities require prompt and accurate diagnosis, accessibility to specialized diagnostic tools remains a concern, particularly in resource-limited settings. Conventional diagnostic devices can be costly and lack portability, hindering their deployment, especially in critical care scenarios. In response to these challenges, our proposed project aims to develop an affordable low-cost smartphone ophthalmoscope. This device, which leverages existing smartphone technology, is intended to facilitate retinal examinations, including cup-to-disc ratio assessment, even in environments where traditional ophthalmoscopes might be limited. The retinal cup-to-disc ratio, also known as the cup-to-disc ratio (CDR), is a measurement used in ophthalmology to assess the optic nerve head and diagnose certain eye conditions, particularly glaucoma. Our proposed smartphone ophthalmoscope aims to record and store retinal images and calculate the cup-to-disc ratio from the images as a means of diagnosing primary retinal health.

Abstract
Patients suffering from respiratory diseases such as COPD, sleep apnea, asthma, pneumothorax, etc. require the use of ventilators for respiratory support. Traditional ventilators can be prohibitively expensive, making them less accessible for patients in need. In developing countries, patients are treated with only oxygen cylinders providing a flow rate of (0-15L/min) due to limited resources. According to treatment guidelines, non-invasive positive pressure ventilation (NIPPV) or high-flow nasal oxygenation (HFNO) is suggested for critical patients. We modified and implemented a low-cost, portable pressure-controlled Bi-level Positive Airway Pressure (BiPAP) machine converting an existing venturi-based low-cost CPAP named Oxyjet. Oxyjet can provide up to 140 L/min flow and Positive End Expiratory Pressures (PEEP) between 5-20 cm H2O. In Oxyjet, the PEEP pressures cannot be switched automatically and physicians need to set the pressure manually. We developed an electromechanical control system incorporating an Arduino-controlled servo motor and a 3D-printed frame for keeping the peep pressure on set .We have developed a time controller system. During inhalation, the higher PEEP pressure is set and during exhalation, the lower peep pressure is set. PEEP automatically be controlled according to the patient’s need ranging from 5-20 cm H2O. This low-cost BIPAP machine could be a blessing to developing countries by providing easy access to affordable respiratory support, improving healthcare accessibility, can be used even at home, and potentially saving countless lives.

Supervisor: Shams Nafisa Ali, Lecturer.
Abstract
Our project introduces an innovative ankle exoskeleton system dedicated to addressing the mobility and stability challenges faced by individuals with various mobility impairments, with a particular focus on those afflicted with gait disorders, including the prevalent condition known as foot drop. Foot drop is a debilitating condition characterized by the inability to lift the front part of the foot due to weakness or paralysis of the muscles involved in dorsiflexion. This limitation greatly hampers one’s ability to walk and maintain balance. Our ankle exoskeleton system plays a pivotal role in rectifying these issues. It offers advanced functionality by assisting and adjusting foot positioning, ankle rotation, and providing supplementary forces to ease the strain associated with self-transportation. By redistributing the force exerted during movement, it not only enhances mobility but also mitigates the risk of falls, substantially improving user confidence and independence. Crucially, this project’s outcomes are not limited to standalone benefits. The integration potential of our ankle exoskeleton with other ongoing medical device projects is a key facet of our approach. This integration offers a comprehensive support network for individuals grappling with mobility and stability impairments. The synergistic interaction of multiple assistive technologies promises to usher in a new era of enhanced mobility, autonomy, and quality of life for individuals living with these conditions. In conclusion, our ankle exoskeleton system stands as a beacon of hope for those burdened by mobility limitations and gait disorders, notably foot drop. It showcases the potential of technology to transform lives, offering not just assistance but empowerment to individuals striving for mobility and stability in their daily lives.
