A medical fluid injector includes: an air detection system for detecting air in the neck of the syringe; a hand-operated control lever for controlling movement of the injector ram; magnetic conductors for delivering magnetic fields from a power head face plate to an internal circuit board to permit detection of different face plates; a tilt sensor detecting the tilt angle of the power head to control the speed of motion brought about by the hand-operated control lever and to control an invertible display; and a monitor microcontroller for monitoring the behavior of the central processing unit to detect and react to error conditions.

A syringe discharge end having a rotatable tubular connector member for engaging a luer connector on medical tubing. The syringe discharge end and the connector have mating threads which are used to affix the connector to the syringe discharge end. Once affixed, the connector is may freely rotate relative to the syringe, while being prevented from axial movement. On its distal end, the connector includes internal threads for engaging external threads on a standard luer connector of medical tubing. To engage the connector to tubing, the connector is rotated relative to the tubing and the syringe to draw the tubing onto the syringe discharge end.

A trocar and trocar obturator assembly having an obturator and a locking mechanism responsive to proximal, axial movement of the trocar obturator is disclosed. The trocar obturator has an elongated obturator shaft having a proximal end and a distal end with a piercing tip mounted thereto. The proximal end of the trocar obturator shaft is slidably mounted in a handle such that the obturator shaft is moveable axially. A protective safety shield having a distal end and a proximal end with a flange member mounted to the proximal end is slidably mounted on the trocar obturator. The safety shield is moveable, axially, between an extended distal position and a retracted proximal position. The protective safety shield is disposed concentrically about the obturator. A lockout arm for locking the safety shield in a locked extended position is mounted in the trocar obturator handle. An actuating collar member is mounted to the proximal end of the obturator shaft in the obturator handle and is moveable with the obturator shaft. The obturator collar disengages the locking arm when moved proximally and engages the locking arm when trocar is armed. The trocar obturator assembly may be concentrically mounted in a trocar cannula having a passageway for receiving the trocar obturator and safety shield. The locking mechanism is actuated by proximal, axial motion of the obturator.
