Dans l'h\u00e9moperfusion et certaines configurations de dialyse, le sang du patient circule directement \u00e0 travers un lit de charbon qui adsorbe les toxines ur\u00e9miques, les surdosages m\u00e9dicamenteux ou les m\u00e9diateurs inflammatoires. Ce mat\u00e9riau doit r\u00e9pondre \u00e0 des crit\u00e8res de biocompatibilit\u00e9 qui vont bien au-del\u00e0 des sp\u00e9cifications industrielles classiques : absence d'endotoxines, de lib\u00e9ration de particules, de m\u00e9taux lixiviables et de r\u00e9sidus chimiques d'activation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Le d\u00e9fi et l'approche PureStar<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Le d\u00e9fi principal :<\/strong>&nbsp;Une puret\u00e9 exceptionnelle alli\u00e9e \u00e0 une stabilit\u00e9 m\u00e9canique sous l'effet du flux sanguin.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Le sang est un fluide complexe compos\u00e9 de prot\u00e9ines, de cellules et de facteurs de coagulation qui interagissent avec toute surface \u00e9trang\u00e8re. Un carbone lib\u00e9rant des particules fines peut provoquer des microembolies ; un carbone pr\u00e9sentant une chimie de surface acide peut d\u00e9clencher l'activation du compl\u00e9ment et une r\u00e9ponse inflammatoire. La structure des pores doit permettre de pi\u00e9ger les toxines cibles sans adsorber les composants sanguins essentiels tels que l'albumine.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Les grades destin\u00e9s \u00e0 la purification du sang de PureStar sont fabriqu\u00e9s en tant que mat\u00e9riaux destin\u00e9s aux dispositifs m\u00e9dicaux, dans le respect de protocoles de contr\u00f4le de la charge microbienne. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Notre charbon sph\u00e9rique \u00e0 base de r\u00e9sine pr\u00e9sente une granulom\u00e9trie homog\u00e8ne et une r\u00e9sistance m\u00e9canique exceptionnelle, ce qui permet d\u2019\u00e9liminer les zones mortes d\u2019\u00e9coulement et l\u2019usure par frottement lors de cycles r\u00e9p\u00e9t\u00e9s.
