A method for purifying blood by using a column which is packed with an adsorbent capable of adsorbing and removing components to be removed from blood and through which blood is externally circulated for purification while satisfying the relation (P120/P5)<=1.3 (wherein P120 represents the blood pressure 120 minutes after the initiation of the blood circulation while P5 represents the blood pressure 5 minutes after the initiation of the blood circulation), and an apparatus therefor. In this method, an increase in the blood pressure during the external circulation can be regulated and blood components are scarcely damaged during the circulatory purification.
La présente invention concerne un procédé de purification du sang. On utilise à cet effet une colonne garnie d'un adsorbant capable d'adsorber et d'éliminer les composants à retirer du sang. On réalise une circulation extracorporelle du sang en vue de sa purification. Ce procédé respecte une relation (P120/P5) </= 1,3 dans laquelle "P120" représente la tension artérielle 120 minutes après le début de la circulation extracorporelle et "P5" représente la tension artérielle 5 minutes après le début de la circulation extracorporelle. L'invention concerne également un dispositif à cet effet. Ce procédé présente l'avantage d'une possibilité de régulation de la tension artérielle pendant la circulation extracorporelle, tout en ne lésant sensiblement pas les composants sanguins pendant la purification par circulation.
