Abstract

Ledit appareil (10) contient une enveloppe (14, 16) avec un passage d'entrée (22) s'étendant jusqu'à l'intérieur de l'enveloppe en une saillie importante (18) de la paroi de l'enveloppe. Ledit passage comporte une extrémité extérieure en haut de la saillie et une extrémité intérieure délimitée par un arrêt d'aiguille (124) situé à l'intérieur de l'enveloppe. Des cloisons auto-étanches (134, 144) agencées dans ledit passage à des intervalles réguliers de l'arrêt d'aiguille divisent ledit passage en une série d'ouvertures d'entrée (136, 154) alignées qui ont chacune leur déversoir de fluide (132, 149). L'un desdits déversoirs (132) mène à un réservoir pompable de fluide de perfusion (46) doté d'une conduite de sortie (76) reliée à un cathéter (24) qui dépasse de l'enveloppe; un autre des déversoirs (149) mène directement à la conduite (83) de sortie de sorte que pendant qu'un premier fluide est pompé du réservoir vers le cathéter, un second fluide peut être introduit dans l'autre ouverture d'entrée pour se mélanger avec le premier fluide qui se déverse dans le cathéter. L'invention porte également sur plusieurs autres types de circulation de fluide de perfusion.
