Summary: | A dual one-way check valve arrangement that may be used for assessing an operating condition of at least one of first and second check valves situated in series along/within a section of a patient-specific section of tubing. A pressure sensor may be associated with at least part of the flow path between the first and second check valves and may be operable to provide an indication of a failed condition of at least one of the first and second check valves. In one embodiment, the pressure sensor may change from a first state to a second state upon fluid pressure within the flow path between the first and second check valves falling below a predetermined level. For instance, the predetermined level may be a cracking pressure of at least one of the first and second check valves. The change in state may be visually discernible on an exterior of the pressure sensor. |
