TAILIEUCHUNG - Experimental and computational study on the effects of wearing neck collar on the carotid blood flow

The effect of football neck collar on the right external carotid blood flow was investigated for ten healthy subjects using Echo-Doppler technique and computational fluid dynamics (CFD) approach. Carotid is in charge of blooding head’s parts including the brain and eyes. | Experimental and computational study on the effects of wearing neck collar on the carotid blood flow Engineering Solid Mechanics 3 2015 27-34 Contents lists available at GrowingScience Engineering Solid Mechanics homepage esm Experimental and computational study on the effects of wearing neck collar on the carotid blood flow Hamidreza Ghasemi Bahrasemana Bahareh Hamzeheib Karim Leilnaharic Arezoo Khosravid and Ehsan Mohseni Languria a Department of Mechanical Engineering Tennessee Technological University Cookeville TN 38505 USA b Department of Biomedical Engineering Amirkabir University of Technology Tehran Iran c Department of Biomedical Engineering Science and Research Branch Islamic Azad University Tehran Iran d Atherosclerosis Research Center Baqiyatallah University of Medical Sciences Tehran Iran ARTICLE INFO ABSTRACT Article history The effect of football neck collar on the right external carotid blood flow was investigated for Received September 6 2014 ten healthy subjects using Echo-Doppler technique and computational fluid dynamics CFD Accepted 22 November 2014 approach. Carotid is in charge of blooding head s parts including the brain and eyes. Hence Available online the evaluation of affected carotid flow by using neck collars is crucial for an improved 23 December 2014 ergonomic design. The testings were divided into three main categories participants without Keywords Computational fluid dynamic wearing neck collar Category 1 wearing neck collar Category 2 and finally wearing neck Echo-Doppler flow collar with an embedded gap adjacent to the carotid artery position Category 3 . The Football neck collar experimental and numerical results revealed that wearing the neck collar Category 2 reduced Carotid artery the average blood carotid flow by 28 compared to the case with no neck collar Category 1 . This average blood carotid flow reduction was improved by 15 when a gap separates the collar from the carotid artery position .
