摘要：

An　analog　device　which　can　simulate　myocardium　bridge　oppresses　mural　coronary　artery　is　designed.　The　device　can　be　used　to　research　the　dynamic　changes　of　the　proximal　and　distal　hoop　stresses.　Meanwhile,　the　independent　regulation　of　the　hoop　stresses　is　realized.　The　“myocardial　bridge　—　coronary　artery”　analog　device　is　built　to　adjust　the　external　pressure　of　the　simulated　coronary　artery　and　the　oppression　level　of　the　myocardial　bridge　and　to　record　the　changes　of　the　hoop　stresses.　The　In　vitro　simulation　experiment　indicate　that　the　anomaly　of　hoop　stress　mainly　occurs　in　the　proximal　end.　As　the　oppression　level　increases,　the　mean　proximal　hoop　stress　and　the　oscillatory　value　(maximum-minimum)　increase　obviously.　The　“myocardial　bridge　—　coronary　artery”　analog　device　can　provide　a　method　to　study　the　influence　of　the　hoop　stress　on　the　mural　coronary　artery　in　vitro.　©　2015,　Silicea-Poligraf　All　rights　reserved.
