Abstract
A syringe for use in a pressurized injection of a fluid includes a syringe barrel including a polymeric material having undergone expansion via blow molding. A preform for blow molding a blow molded syringe is described, the preform including a proximal end having a retention mechanism adapted to connect to the syringe to a powered injector, a distal end having a syringe outlet section, and a barrel section between the retention mechanism and the syringe outlet section, wherein the barrel section is adapted to be blow molded to form a cylindrical wall of a syringe barrel defined between the retention mechanism and the syringe outlet section.
Claims20
A preform for a blow molded syringe, the preform comprising:
- a proximal end having a retention mechanism, the retention mechanism adapted to connect the syringe to a powered injector;
- a distal end having a syringe outlet section;
- and
- a barrel section between the retention mechanism and the syringe outlet section,
- wherein the preform comprises at least one polymeric material,
- wherein the barrel section is adapted to be blow molded to form a cylindrical wall of a syringe barrel defined between the retention mechanism and the syringe outlet section, and
- wherein the syringe outlet section is formed during an injection molding process of the preform and is not substantially altered during a blow molding expansion process of the preform.
A preform for a blow molded syringe, the preform comprising:
- a proximal end having a retention mechanism, the retention mechanism adapted to connect the syringe to a powered injector and comprising at least one flange, wherein the retention mechanism is not substantially altered during a blow molding expansion process;
- a distal end having a syringe outlet section comprising a connector adapted to connect with a complementary connector of a fluid path element, wherein the connector is not substantially altered during a blow molding expansion process;
- and
- a barrel section between the retention mechanism and the syringe outlet section,
- wherein the preform comprises at least one polymeric material, and
- wherein the barrel section is adapted to be blow molded to form a cylindrical wall of a syringe barrel defined between the retention mechanism and the syringe outlet section.
