Dialysis machine having auto-connection system with roller occluder
First Claim
1. A medical fluid system comprising:
- a medical fluid machine;
a disposable set operable with the medical fluid machine;
a mechanism operable to move at least one medical fluid supply line into connection with the disposable set to allow fluid communication between the at least one medical fluid supply line and the disposable set;
a first occluder positioned to occlude the at least one medical fluid supply line while the at least one medical fluid supply line is being moved into connection with the disposable set;
a second occluder positioned to occlude the at least one medical fluid supply line while the at least one medical fluid supply line is being moved into connection with the disposable set, the second occluder located between the first occluder and the disposable set; and
wherein the first and second occluders and the mechanism are operated such that (i) only the second occluder is occluding the at least one medical fluid supply line at a first time before a cap at an end of the at least one medical fluid supply line is removed; and
(ii) only the first occluder is occluding the at least one medical fluid supply line at a second time before the cap is removed.

Abstract
A medical fluid or dialysis system includes an auto-connection mechanism that connects connectors from the supply bags to dialysis cassette ports or cassette supply lines. The system provides for multiple, e.g., four, supply bags, which can be connected to a manifold of the auto-connection mechanism. Tip protecting caps that protect the supply line ends and cassette ports or cassette supply line ends are made to be compatible with the auto-connection mechanism. The auto-connection mechanism removes all the caps and connects the supply lines to the cassette. At least one roller occluder is provided that occludes the supply tubing prior to the tip protecting caps being removed. The roller occludes prevent medical dialysis fluid from spilling out of the supply lines between the time that the caps are removed and connection to the cassette is made.
