FLUID INJECTION APPARATUS HAVING ANTI-ROTATION ELEMENTS TO LIMIT SYRINGE PLUNGER ROTATION |
摘要 |
The fluid injection apparatus is adapted for use with a syringe and includes an injector and a pressure jacket associated with the injector. The injector includes a drive piston having a plunger engaging end. The syringe includes a body and a plunger movably disposed within the body, the plunger having a proximal end adapted for engagement by the plunger engaging end of the drive piston. An anti-rotation connection is formed by complementary anti-rotation elements associated with the proximal end of the plunger and the plunger engaging end of the drive piston to limit rotation of the plunger within the syringe body.
