Devices Used by 112 Personnel in the Covid-19 Pandemic Process, Validation and Problems Encountered

The emergency health service is for all interventions that are made up of people who have received special education in their field, who work together in order to provide the best emergency response to the sick and injured in the shortest time possible in line with the possibilities available. In this context, although the emergency health service provided during the pandemic process requires the implementation of special procedures for healthcare professionals, it is important in the validation of the biomedical devices used during the provision of this service. Especially the fact that this process was a disaster that took place in an unexpected time period caused everyone to be caught unprepared and this situation caused the current workload of healthcare workers to increase even more. In this study, we conducted a literature search to shed light on the problems experienced by 112 emergency healthcare professionals during the pandemic period and how the validation of the biomedical devices used by these personnel in the ambulance should be. The type of research is descriptive research. The Covid-19 pandemic was accepted as a case and the literature was reviewed, with this case being the focus. During the literature search, up-to-date keywords such as "emergency health service, Covid-19, disaster preparedness, emergency aid unit employees, biomedical device technologies", which are also mentioned in the keywords, were scanned. Care was taken to ensure that the studies included in the review section were up to date and in accordance with the academic guide. In addition, due to the limitation of resources in the validation section of the research, assistance was received from the relevant legislation and expert medical company engineers and from the active staff in the field of healthcare professionals' problems. As a result of this research, we have reached the conclusion that legal regulations should be made regarding the problems experienced by healthcare professionals due to the pandemic and that existing standards related to device validation should be updated after the pandemic.

Mathematical Modeling of Enhanced Whale Optimization Based Power Quality Enhancement Using Unified Power Quality Conditioner for Implantable Biomedical Devices

Implantable biomedical systems that enable the majority of the functions of wireless implantable devices have made significant progress in recent years. Nonetheless, due to limited miniaturization, power distribution limits, and the unavailability of a stable link between implants and external devices, such systems are primarily limited to investigation. Generating electricity from natural sources and human body movement for implantable biomedical devices has emerged as a viable option. Nowadays, energy sources become the emerging use of electricity grid which has formed new challenges for the effectiveness of power quality, efficient energy utilization and voltage stabilization for biomedical applications. Power quality in the implementation of the smart grid in biomedical devices is regarded to be the most problematic. APFs (Active Power Filter) are preferred to reward the related problems, mainly because they can quickly filter out of the PQ and are a dynamic compensation. The UPQC with a PI control unit with DC source to be converted to a three stage inverter based on Enhanced Whale Optimization Algorithm (EWOA) was precisely implemented in the article in order to eliminate voltage and current harmonics inadequate. Similarly, UPQC also used the Enhanced Whale Optimization Algorithm (EWOA). In this approach, UPQC along with EWOA (Enhanced whale optimization) has been introduced for voltage and current harmonics elimination defect specifically. Similarly, EWOA was too implemented with UPQC. UPQC & EWOA conducted a performance estimate by estimating a simulation, results on comparing the parameters of THD levels, load current and voltage. The performance estimate is also used and the results achieved are shown. In order to analyze THD values and validate the system performance, performance estimates are built and compared with THD values, load voltage and current parameters.

Polymer nanofibers for biomedical applications: advances by electrospinning

Background: The demand for novel biomaterials has been exponentially rising in the last years as well as the searching for new technologies able to produce more efficient products in both drug delivery systems and regenerative medicine. Objective: The technique that can pretty well encompass the needs for novel and high-end materials with a relatively low-cost and easy operation is the electrospinning of polymer solutions. Methods: Electrospinning usually produces ultrathin fibers that can be applied in a myriad of biomedical devices including sustained delivery systems for drugs, proteins, biomolecules, hormones, etc that can be applied in a broad spectrum of applications, from transdermal patches to cancer-related drugs. Results: Electrospun fibers can be produced to mimic certain tissues of the human body, being an option to create new scaffolds for implants with several advantages. Conclusions: In this review, we aimed to encompass the use of electrospun fibers in the field of biomedical devices, more specifically in the use of electrospun nanofibers applications toward the production of drug delivery systems and scaffolds for tissue regeneration.
