Abstract

A tubing set suitable for use in co-operation with a hemodialysis machine includes an out-tube for supplying the blood from the patient to a filter of the machine, an in-tube for supplying the blood from the filter back to the patient, a drip chamber placed along one of the tubes, adapted to let the blood drip through an air buffer, and a vial gate for the connection of vials containing drugs to be delivered into the blood. The vial gate includes a delivery lumen, suitable for delivering the drug from the vial to the drip chamber, and a vent lumen, suitable for providing air inside the vial in order to replace the delivered drug.
