1. A disposable apparatus for a blood purification system comprising:
- a rigid plastic substrate, wherein said rigid plastic substrate has a H shape comprising a left member, a right member, and a connecting member, wherein each of the left, right, and connecting members house at least one flow path therein and wherein the left member comprises a first external port and the right member comprises a second external port that faces the first external port; and
a first flexible tube having a first end and a second end, wherein the first flexible tube is external to the rigid plastic substrate, wherein said first end of the first flexible tube is attached to the first external port on the left member, wherein said second end of the first flexible tube is attached to the second external port on the right member, and wherein said first flexible tube serves to connect a portion of the at least one flow path in said left member to the at least one flow path in said right member.
