Therefore, the mechanical properties of the dialysis sets are evaluated depending on the selected physical parameters. For this reason, the sets are subject to temperature changes and changes in the pressure of the peristaltic pump occlusion cylinders. To evaluate the mechanical properties of the dialysis sets, the sets were subjected to stress tests and subsequent tests. The results were processed and analysed.","PeriodicalId":357085,"journal":{"name":"International Conference on Biomedical Electronics and Devices","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127745742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the paper, we describe the electrical design of the plug-in module, which is intended for a transmission of the digital data from the computer. Data are sent by using the controlling SW connected to the parallel port in the plug-in module. An essential part of the proposed module is the three-channel 12 bit D/A converter AD 7398. This converter is able to simultaneously send data from all the three outputs. The converter output is unipolar in the volts units. For this reason, the transmitted signals are adjusted by using the differential amplifiers in order to convert them to the bipolar. The signal’s amplitudes are decreased to the millivolts level by using the voltage dividers. On the base of this solution, the Einthoven ECG leads may be detected.","PeriodicalId":357085,"journal":{"name":"International Conference on Biomedical Electronics and Devices","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116423319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent announcements to consumers, by the United States (U.S.) Centers for Disease Control (CDCs), to discard all Romaine lettuce because of bacterial contamination has resulted in hundreds of millions of dollars in losses to growers and processors. Unfortunately, current microbiological testing of samples of specialty crops (whole fruits, leaves of spinach, etc.), as specified by FDA’s Bacteriological Analytical Manual (BAM), requires at least 48 hours to perform the complicated, time-consuming and costly steps of soaking, , concentration, enrichment, plate count or PCR to detect pathogens on these samples. Further complicating the BAM analyses are the realities that: 1) both PCR and ELISA are unable to distinguish between live and dead cells and 2) only a few samples out of as many as 100,000 fruits, vegetables or leaves of multi-ton batches of produce can be BAM tested. A Non-clogging Biomolecular Phage Filter has been developed to simultaneously capture, concentrate and isolate small numbers of pathogens from large volumes of produce wash water. This phage filter can then be evaluated to screen for live versus dead cells and ID the specific pathogen in minutes. Capture efficiencies of greater than 94% have been demonstrated.","PeriodicalId":357085,"journal":{"name":"International Conference on Biomedical Electronics and Devices","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128778749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The challenge of suppression or noise attenuation has led to the search for improved techniques in order to preserve important characteristics of the image, but, on the other hand, there is no solution available to completely solve the problem, boosting the production of the work proposed here.

Ischemic stroke is caused by the blood clot and plaque present in the blood vessel. Hemorrhagic stroke, on the other hand, occurs when a rupture happens in the cerebrovascular artery or mid-cerebral artery causing impairments in blood flow and hence the supply of oxygen to the cerebral tissues. The current research analyses the blood flow velocity, the pressure profile of blood clot and plaque, and the condition at which ischemic and hemorrhagic stroke occurs. Simulation studies show the pressure on the blood vessel walls under ischemic and hemorrhagic stroke conditions and also that under nominal blood flow velocity the hemorrhage does not occur, but when the velocity is sufficient enough to increase the pressure on the wall, rupture of the mid-cerebral artery takes place. The simulation assumes the blood flow to be laminar, non-Newtonian, viscous, incompressible, and the arterial wall as elastic. Using the simulation model, an approach to classifying ischemic and hemorrhagic stroke using near infrared spectroscopy has been proposed in the paper.","PeriodicalId":357085,"journal":{"name":"International Conference on Biomedical Electronics and Devices","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127266895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are multiple techniques for the identification and for the assessment of user related risks, that may be chosen according to the step of the design (preliminary feasibility studies, minimum viable product assessment, verification and validation) and considering cognitive processes and information processing mechanisms of users, which may lead to errors. Some techniques are more adequate for a quick-and-dirty approach, during early stages of design: these include expert reviews, discussions among focus groups, standard reviews and heuristic analyses. Other techniques are adequate for a more detailed and systematic analysis of risk, in more advanced design stages, with a failure mode and effect analysis (FMEA) approach, including time-and-motion studies and task analyses. Lastly, user tests with the help of rapid prototypes, perhaps involving alternative embodiments to be studied, are very adequate for verification and validation of the interface. Usability analysis techniques should be part of the toolbox of a biomedical engineer and they should be carefully chosen. Each technique, regardless the step it is used, should allow the designers to define a precise level of risk in terms of probability, severity. Moreover, usability risk minimisation measures shall be measurable and able to be quantified, as well as the impact of risk mitigation strategies. For this reason, usability risk minimisation measures should be classified according to regulatory requirements as “safe by design”; “alarms and protections” and “information for safe use”. Each class of risk minimisation measure should be then given a measurable risk reduction score, so that the risk assessment can be completed in a repeatable and regulatory compliant way.","PeriodicalId":357085,"journal":{"name":"International Conference on Biomedical Electronics and Devices","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129132618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
