Abstract
Investigation in thermal and electrical properties of human tissues is now a very important issue for the design of medical devices, especially in Bangladesh where cost effective and safety feature with flexibility and future compatibility are the key issue. Introduction Medical devices including imaging devices, therapeutic instruments and physiological monitoring rely on comprehensive knowledge of interaction between human tissues and electrical and thermal energies. These interactions impact the optimization of dose, safety of dose, quality of image, efficacy of therapy and clinical usage. However, despite global progress, there is a paucity of local studies and this information gap is one of the major barriers to the development of cost effective and safe technologies that the healthcare system of Bangladesh demands. This study uses longitudinal data (1994-2023) to reveal trends in performance and the implications for device innovation. We used a retrospective analysis of 30 years (1994–2023) data including five key parameters: Dosage Optimization (%), Safety Index, Imaging Quality Score, Therapy Effectiveness (%), Adoption Rate (%). The data patterns were subjected to statistical analysis in order to identify relationships and performance fluctuations with time. Descriptive analysis emphasized mean values and comparative evaluations captured changes in therapy efficacy, safety and imaging quality. The clinical usability was highlighted as the relationship between the safety index and the adoption rate. Contextual analysis linked the observed trends of technology to the biomedical design needs of Bangladesh in terms of cost, regulatory compliance and sustainability of medical devices. The results showed that there was a noteworthy deviation among the measured parameters analyzed. Dose control optimization increased over time, reaching almost 100% in (2013), suggesting significant further improvement in delivered energy control. The value of safety index fluctuated intermittently (from 2.34 in 2003 to 9.93 in 2002), indicating the difficulty in keeping stable safety performance. Imaging quality scores (as high as >90) cumulatively illustrated that the quality of imaging is generally great and saw significant peaks in 2011 (99.4) and 2018 (99.98), indicating improvements in noninvasive diagnostics. Effective treatment also increased over time with a rate of more than 90% in (1996, 2003, 2008 and 2017) demonstrating an improved reliability. Adoption rates fluctuated usually around 50% or less until (2008, 2010 and 2013) then passed 75% in (2017). This contradiction demonstrates the potential that existed but also points to the fact that socio-economic barriers prohibited broader acceptance. Our results suggest that device development for Bangladesh can be aimed towards durable safety-conscious, cost-sensitive design that also considers context-specific usability to optimally foster effectiveness and broader clinical uptake.
