A single-use, single-patient, or patient-specific tubing set (300) is disclosed. The tubing set (300) includes at least one check valve (304), along with a use indicator (320). This use indicator (320) provides a visual indication when the tubing set (300) has been used for an injection. In this regard, a piston (340) moves from one position to another when exposed to a certain fluid pressure. |
