Design of protective mask and UV decontamination box against biological threats

The confrontation with biological hazards has been an ongoing aspect of human endeavor from the dawn of civilization. Epidemics have profoundly influenced the societal structures and lifestyle choices of human populations. In response to pandemics, the deployment of personal protective equipment (PPE) has become a cornerstone strategy for infection prevention. Masks, in particular, have played a crucial role during such times, offering defense not only against specific pandemic-induced infections but also against a broader spectrum of respiratory diseases. However, the reliance on petroleum-based plastics for the production of a significant fraction of PPE presents notable recycling challenges. The inability to recycle a substantial volume of health sector-related plastic products, owing to their transformation into biohazardous waste, exacerbates environmental pollution. The single-use paradigm of surgical masks introduces both ecological and economic dilemmas, concurrently underscoring the necessity for ergonomic enhancements. Observations have recorded a decrement in the protective performance of surgical masks following extended periods of usage. This research delves into the antimicrobial capabilities of silver-infused threads and the odor-neutralizing attributes of coffee charcoal yarn within the context of mask fabric selection. Additionally, it scrutinizes the efficacy of UV-C light as a biocidal agent for the sanitization of mask storage containers. The exploration of reusable mask models places a premium on augmenting wearer comfort and health over prolonged durations, alongside facilitating straightforward post-use decontamination processes. The overarching objective is to bolster the protective efficiency of medical masks, refine their ergonomic design, and, consequently, furnish wearers with elevated levels of protection sans discomfort during extended usage. Such advancements aim to mitigate transmission risks and curtail the generation of hazardous waste, thereby diminishing the environmental footprint associated with mask utilization.
