Device for intracorporeal and and extracorporeal purification
First Claim
1. Device for intra- and extracorporeal purification comprising a reservoir for exchange solution (11), an admission conduit (5) for exchange solution connected at one end to this reservoir (11) and discharge control means (6) in order to manage the circulation of the exchange solution in the admission conduit (5) as well as an evacuation conduit (7) of polluted solution, evacuation means (13) for the polluted solution situated at one end of the evacuation conduit (7) and discharge control means (8) in order to manage the circulation of the polluted solution in said evacuation conduit (7), characterised by the fact that the reservoir for exchange solution (11) and the evacuation means (13) of the polluted solution are connected either directly to a site of the patient (P) with the help of a specific element (10) in order to perform peritoneal dialysis or to a circuit for extracorporeal circulation (1,2,3,4) which is itself connected to the patient in order to perform extracorporeal blood purification, and by the fact that a control module (15) comprises computation means (15b) which control the discharge control means (6) of the exchange solution and the discharge control means (8) of the polluted solution in order to allow for an operation mode of the device for peritoneal dialysis and computation means (15a) which control the discharge control means (6) of the exchange solution, the discharge control means (8) of the polluted solution and the circulation in the extracorporeal circuit (1,2,3,4) in order to allow for an operation mode of the device for extracorporeal purification of blood.

Abstract
A device for intracorporeal and extracorporeal purification of patients suffering of renal failure, the purification being designed to clean up the patients'"'"' body by removing undesirable elements, in particular urea and water, the device for intracorporeal and extracorporeal purification allowing to combine the different known treatment methods, in particular peritoneal dialysis, hemofiltration, hemodialysis and ultrafiltration, the latter being performed by using preferably a peripheral vascular access.

10. Device for purification, characterised by the fact that it comprises on the one side a circuit for extracorporeal circulation (1,2,3,4,10) comprising corresponding steering, control and security means, this circuit being generally adapted to transport blood or exchange solution into and out of the body by a unique site or by two separated sites of the patient, and/or on the other side computation means (15a) adapted to control the discharge control means (6) of the exchange solution, the discharge control means (8) of the polluted solution and the circulation in the extracorporeal circuit (1,2,3,4), these elements being adapted to co-operate with an existing device for purification by peritoneal dialysis and allowing this latter to carry out the different treatment methods, in particular an operation mode of the existing device for extracorporeal purificationn of blood by hemodialysis, hemofiltration and/or ultrafiltration.
