Abstract
A combined arterial-venous blood flow set comprises connected lengths of flexible tubing for receiving blood from a patient, for conveying the blood to a blood processing device such as a dialyzer or an LDL filter, and for returning the blood to the patient. An optional first bubble trap chamber is connected in series flow between two of the lengths of tubing at a flow position downstream from the patient and upstream from the blood processing device. A second bubble trap chamber is connected in series flow between two of the lengths of tubing at a flow position downstream from the blood processing device and upstream from the patient. A first portion of the tubing which is in a flow position upstream from the blood processing device extends by the second bubble trap chamber, and is physically, laterally connected to it without direct flow connection. This helps to stabilize the positioning of components of the flow set and to reduce confusion in set-up and priming.
