BLOW-MOLDED SYRINGE FOR USE WITH AN INJECTOR

摘要

A syringe for use in pressurized injection of a fluid is provided herein. The syringe includes a syringe barrel comprising a polymeric material having undergone expansion by stretch blow molding and by compression molding of an inner diameter of the barrel with a core member. In certain configurations of the syringe barrel, the stretch blow molding is provided through a nozzle of the syringe. Similarly, according to a further embodiment, a syringe for use in pressurized injection of a fluid is provided. The syringe includes a syringe barrel comprising a polymeric material having undergone expansion by stretch blow molding and by shrinking an inner diameter of the syringe barrel about a core member.

主权项

1. A preform for stretch blow molding a syringe, the preform comprising:
a body having a distal end, a proximal end, and a circumferential wall therebetween and comprising a polymeric material suitable for stretch blow molding to form a syringe body; and a first opening at the distal end of the body for inserting a stretch member for stretching the preform during a stretch blow molding process, wherein an inner walls of the stretch blow molded syringe body have a substantially uniform inner diameter for slidably receiving a plunger.
