Abstract

Dispositif portable pour hémofiltration.L’invention concerne un dispositif portable pour hémofiltration qui comporte un hémofiltre (1) dont la coque plastique externe est fendue de plusieurs fentes (2) de telle manière à permettre un contact des fibres (3) contenues en son sein avec le milieu environnant. Cet hémofitre (1) est entouré d’une enveloppe plastique souple et hermétique (4) qui est fixée sur les pourtours des deux extrémités de la coque. Deux faces de cette enveloppe plastique sont fixées, par adhésif ou tout autre procédé de collage (5), sur deux plaques rectangulaires rigides échancrées en leurs milieux et parallèles (6). Entre les quatre coins des deux plaques sont montés quatre ressorts et parallèles (6). Entre les quatre coins des deux plaques sont montés quatre ressorts (7). Des tubulures en plastique médical sont reliées aux deux extrémités de l’hémofiltre. Après montage, on procédé a la création d’un vide à l’intérieur de l’hémofiltre et de l’enveloppe plastique par aspiration et on tend les ressorts. Le sang du patient recueilli d’une veine centrale passe à travers l’hémofiltre pour revenir via le second tube vers la deuxiéme branche du cathéter. La pression négative créée par l’extension des quatre ressorts provoque l’ultrafiltration du sang à travers les fibres de l’hémofiltre et ainsi du liquide s’accumule dans l’enveloppe plastique.Figure pour l’abrégé : fig 1b
