ABSTRACT:
A medical fluid injection system comprises a flexible conduit, a supply device, a movable element, and a blocking condition detection device. The supply device supplies a pressurized medical fluid through the flexible conduit. The movable element is moved for forcing the flexible conduit in a stressing direction to cause creep in the flexible conduit. The blocking condition detection device detects whether or not the flexible conduit is forced in an anti-stressing direction opposed to the stressing direction. In a specific form of the present invention, a monitor may be provided for monitoring whether the movable element is exactly moved or not.
