Conventional laboratory approaches are time consuming, need blood component separation and a regular visit to clinical labs. The burden of PT measurement on the clinical laboratory is huge globally, which raise need for point of care, quick and user-friendly device. Methods: In this study we have proposed a handheld device based on the image processing for the PT/INR detection. Cost effective disposable strips were fabricated using thromboplastin as reagent. Device and strips were tested for 100 samples in clinical set up as per the ISO standard 17593 “Clinical laboratory testing and in vitr o medical devices - Requirements for in vitro monitoring systems for self-testing of oral anticoagulant therapy”. Results: Data was compared with the values obtained from clinical laboratory using automated coagulometer T Coag DT-100 (Trinity), and commercially available Point of Care (POC) device from Roche, Diagnostics. A correlation coefficient (r) of 0.87 & 0.77 was observed between lab vs Chitra device and Chitra device vs commercially available device, respectively. Conclusion: Clinically accepted correlation may be obtained after automation of the strip fabrication technique. The proposed device is cost effective and easy to operate and works on the novel approach of image processing. To best of our knowledge this is the first report on the image processing-based PT/INR monitoring device. blood samples were collected through venipuncture from all subjects recruited in the study for analyzing PT value of patients in laboratory and comparing the value with the device in test. Plasma was separated by centrifuging the blood samples at 1500g for 10min and analyzed on an automated coagulometer T Coag DT-100 (Trinity) using neoplastin CI Stago an ISI 1.4).","PeriodicalId":415155,"journal":{"name":"Research in Medical & Engineering Sciences","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129195963","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}

Usually, masks are indispensable for preventing both virus spread and inhalation. There are various types of masks from woven to nonwoven fabrics on the market, and the protective effect to virus varies from a few percent to over 99%. In general, the performance of a mask can be represented by the Particle Filtration Efficiency (PFE) and Pressure Drop (PD) similar to an air filter. PFE corresponds to a measure of virus protection and PD to ease of breathing. Therefore, better performing masks have higher PFE and lower PD. PFE and PD are in a strong relationship with each other, that is, whenever we try to increase PFE, PD will increase. Generally, electrets are given to increase PFE in keeping PD low such as HEPA and ULPA. The electret, however, loses the effectiveness by water vapor in air, etc. Z-nanofiber sheet mask, which is produced by Z-melt spinning method (1) of polypropylene (PP), can solve those problems, because nanofiber can adsorb virus and bacteria by the van der Waals force without giving electrical properties, that is socalled hydrophobic bond, which induces the washable property of the mask. Table1 shows the PFE and the PD of seven Nanofiber sheet samples of PP. PFE was measured by using the NaCl particles whose diameters are from 25nm to 131nm, where measurement conditions are 100cm2 of measurement area, 31.8L/min of ventilation volume, and 5.3cm/sec of flow velocity, respectively. PFE and PD of each sample are more than 99% and less than 70Pa, respectively, which means that we can prepare the non-suffocating mask with high virus capture efficiency [1].","PeriodicalId":415155,"journal":{"name":"Research in Medical & Engineering Sciences","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131324084","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}
