Abstract
An interface device between a hemodialysis machine and venous and arterial tubes includes: a first port adapted to be connected to an output port of the hemodialysis machine and a venous port to inject blood into the venous tube. The interface device includes a second port adapted to be connected to an input port of the hemodialysis machine and an arterial port for receiving blood from the patient from the arterial tube. The interface device is further adapted to selectively allow or prohibit the passage of blood between the first and second ports and the venous and arterial ports respectively.
Claims13
An interface device between a hemodialysis machine and a venous tube intended to be connected to a patient's circulatory system containing blood for transferring the blood from the hemodialysis machine to the circulatory system, the interface device comprising:
- a first port adapted to be connected to an output port of the hemodialysis machine;
- a venous port to inject the blood into the venous tube;
- the interface device being adapted to selectively adopt a first configuration in which the blood is restricted from passing between the first port and the venous port and a second configuration in which the first port is connected to the venous port to allow the blood to pass from the first port to the venous port, characterized in that the interface device is also adapted to form an interface between the hemodialysis machine and an arterial tube for connection to said patient's circulatory system to transfer the blood from the circulatory system to the hemodialysis machine, said interface device also comprising:
- a second port adapted to be connected to an input port of the hemodialysis machine;
- an arterial port for receiving the blood from the patient via the arterial tube, the interface device being further adapted to restrict the blood from passing between the second port and the arterial port when the interface device is in the first configuration and to allow the passage of the blood between the second port and the arterial port when the interface device is in the second configuration,
- wherein the interface device also comprises a third port, the interface device being adapted to selectively adopt an unlocking configuration distinct from said first and second configurations, in the unlocking configuration the third port being connected to only one of said venous port or arterial port while the first port and the second port are respectively isolated from the venous port and the arterial port, wherein the venous port and arterial port are isolated from each other.
