A syringe includes a body and a plunger movably disposed within the body. The syringe may be used with an injector including a drive member. The drive member preferably includes at least one pin adapted to form a retractable abutting connection with an interior of a plunger to enable the drive member to retract the plunger with the body of the syringe.

Orange syringe plunger cover

A plunger cover for use with a syringe includes a sealing portion adapted to form a seal with the syringe and a central portion adapted to contact fluid within the syringe. The central portion can, for example, be more rigid than the sealing portion. The sealing portion and the central portion are connected in an overmolding process. The sealing portion can, for example, be formed from a thermoplastic elastomer or a thermoplastic polyurethane. The central portion can, for example, be formed from polypropylene, acrylonitrile butadiene styrene, polycarbonate or copolymers thereof.

A fluid path set for a fluid delivery system includes a tube coil that is designed to optimally position one or more volumes of a pharmaceutical within an ionization chamber to measure and prepare a pharmaceutical dose for administration to a patient. Methods for priming at least a portion of the fluid path set include placing a tubing section of the fluid path set in fluid connection with a source of a radiopharmaceutical, and placing the tube coil within a dose calibrator of the fluid delivery system. A volume of the radiopharmaceutical may be pumped through the tube coil, the tubing section, and an additional tubing section, and the dose calibrator may be monitored to determine if a measured activity level is substantially equal to or above a predetermined activity level, and if so, it may be concluded that the tubing section of the fluid path set has been primed.

Radiopharmaceutical administration methods, fluid delivery systems and components thereof

A fluid path set for a fluid delivery system includes a tube coil that is designed to optimally position one or more volumes of a pharmaceutical within an ionization chamber to measure and prepare a pharmaceutical dose for administration to a patient. The fluid path set includes a medical fluid component having a first tubing section for connection to a source of a medical fluid, a pharmaceutical component having a second tubing section for connection to a source of a pharmaceutical, and a coil assembly which includes the tube coil. The tube coil may be maintained in a desired dimensional geometry by means of a core structure around which the tube coil is positioned.

A syringe plunger includes a wall having an inner surface and one or more inwardly projecting flanges disposed on the inner surface of the wall. Preferably, the inner surface of the wall defines a retaining shoulder formed along an axial plane thereof. An injector drive member preferably includes at least one retaining member adapted to engage the retaining shoulder of the syringe plunger to allow the drive member to retract the plunger with the body of the syringe. Further, the drive member preferably includes one or more outwardly extending flange members adapted to be engaged by the inwardly projecting flanges of the syringe plunger. When the syringe body is rotated, the at least one retaining member on the drive member is retracted and disengaged from the retaining shoulder of the syringe plunger.
