Abstract
A blood chamber for an extracorporeal blood circuit comprises a blood inlet port (2), a blood containment chamber (3), a first conduit (8) which connects the blood inlet port (2) with the blood containment chamber (3) and which has an end tract (8a) that terminates in the blood containment chamber (3) with a horizontal inlet component. The first conduit (8) comprises a pre-terminal tract (8b) which precedes the end tract (8a) and which has at least a second horizontal component which is directed in an opposite direction to the horizontal inlet component. The blood chamber is used in an arterial line of a dialysis set for guaranteeing a regular and gentle blood flow.

A blood chamber for an extracorporeal circuit, comprising:
- a blood containment chamber having a blood inlet and a blood outlet, said blood outlet being situated at a lower height than said blood inlet, said blood inlet being at least partially vertically arranged, said containment chamber being delimited by a wall having a recess situated above said blood inlet;
- a blood inlet port situated below said blood inlet;
- a first conduit connecting said blood inlet port to said blood containment chamber, said first conduit having an end tract which terminates in said blood inlet and which has at least a horizontal inlet component, said first conduit comprising a pre-terminal tract which precedes said end tract and which has at least a second horizontal component directed oppositely to said horizontal inlet component.
A process for transporting extracorporeal blood through a blood chamber, comprising stages of:
- causing a blood flow through a pathway comprising an ascending first tract, a second tract following said first tract having at least a horizontal component, a final third tract, following said second tract, having at least a horizontal component directed in an opposite direction to at least a horizontal component of said second tract;
- directing said blood flow from said pathway to a blood containment chamber;
- removing the blood from said containment chamber.
