The invention relates to a bicarbonate container for one time use in dialysis apparatus for hemodialysis that is a rigid plastic container including a two-channel plug-in connector for connection of the container to a dialysis apparatus.
A bicarbonate container with a two-channel plug-in connector is already known from EP-0 575 970 A2, wherein the container is shown as a flexible bag. Since, because of the two-channel plug-in connector for the connection to a dialysis apparatus, the inlet and outlet for the solution circuit are disposed at the same location of the container, the container must include a conduit which extends within the container from one of the two plug-in connector channels to the opposite end of the container so that the solution can flow through the whole bicarbonate container. In the container disclosed in EP 0 575 970 A2, a flexible hose extends from one of the two plug-in connector channels through the interior of the bag to the end thereof about opposite the plug-in connector.
However, this arrangement requires relatively high manufacturing expenses and, more importantly, the end of the hose is not fixed so that, after filling the bag with bicarbonate, the end of the hose may not be in the most desirable position within the bag whereby the solution conducted through the bag flows only through part of the bicarbonate contained in the bag.
It is the object of the present invention to provide a bicarbonate container for a hemodialysis apparatus which is easy to manufacture and wherein the opening of the duct extending from the plug-in connection to the opposite end of the container is securely arranged at an optimal location.
