Title (EN) PROCESS FOR PREPARATION OF LYOPHILISED CONTRAST AGENTS
(FR) AMELIORATIONS RELATIVES AUX MILIEUX DE CONTRASTE
Abstract: front page image
(EN)The invention provides a process for the preparation of a fluorocarbon-containing lyophilised contrast agent which comprises lyophilising lyophilisable precursor material contained in one or more containers in a lyophilisation or like vacuum chamber, introducing said fluorinated gas into said chamber and effecting sealing closure of said container or containers, characterised in that, following closure of said container or containers, an overpressure of an atmoshperic gas is applied to said chamber and said fluorocarbon gas is allowed to condense in a condensation vessel connected to said chamber.
(FR)La présente invention concerne un procédé permettant de préparer un milieu de contraste lyophilisé renfermant du fluorocarbure, consistant à lyophiliser d'abord un matériau précurseur lyophilisable contenu dans un ou plusieurs récipients dans une cloche à vide de lyophilisation ou une enceinte similaire, à introduire ensuite ledit gaz fluoré dans la cloche précitée avant de fermer par scellement le ou les récipients précités. Cette invention est caractérisée en ce que après fermeture de ce ou de ces récipients, on applique une surpression d'un gaz atmosphérique sur ladite cloche, puis on permet audit gaz fluoré de se condenser dans une cuve de condensation reliée à ladite cloche.
