用于与注射器一起使用的吹塑成形针管
摘要：
在此提供了一种用于加压注射流体的针管。该针管包括针管筒，该针管筒包含聚合物材料，该聚合物材料已经历通过拉伸吹塑成形并且通过压缩成形具有芯构件的该筒的内径的膨胀。在该针管筒的某些配置中，该拉伸吹塑成形通过该针管的喷嘴提供。类似地，根据另一实施例，提供了一种用于加压注射流体的针管。该针管包括针管筒，该针管筒包含聚合物材料，该聚合物材料已经历通过拉伸吹塑成形并且通过围绕芯构件收缩该针管筒的内径的膨胀。
摘要（英）：

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.
