ABSTRACT:
The present invention provides a fluid injection apparatus for injecting viscous fluids directly from a syringe in which it is commercially delivered. The fluid injection apparatus includes a cylindrical syringe sleeve into which the syringe is inserted from one end with a small hole at the other end of the sleeve through which the syringe needle or cannula protrudes. The apparatus includes a locking head assembly for retaining the syringe in the cylindrical syringe sleeve which includes a top plate and a locking flange which engages with the flange for locking the head assembly to the cylinder. The plunger in the syringe is discarded and when the locking head assembly is placed on the cylindrical syringe sleeve an internal flange with a gasket located on it is inserted into the top of the syringe chamber forming a seal. The head assembly includes a tube coupling for connecting a pressurizing gas such as air to the cylinder through the interior of the internal flange for pressurizing the syringe for expelling the viscous oil through the needle or cannula.
