Method of preparing a syringe for injection

Abstract

The present invention provides simple manual methods of filing a syringe, wherein the wastage of liquid is reduced, and the need to replace a damaged delivery needle is avoided. The methods of the present in invention comprise the filling of a distributing syringe with a liquid from a supply vial, placing the distributing syringe in communication with at least one receiving syringe, and transferring the liquid to the receiving syringe whereon the receiving syringe is filled. Communication between the distributing syringe and the receiving syringe is preferably achieved by inserting the hypodermic needle of the distributing syringe into the nozzle of the receiving syringe. A multiplicity of syringes may be filled from one distributing syringe by repeating the steps of needle insertion and liquid transfer. A delivery needle is attached to each receiving syringe, which is then used to administer the liquid to an animal or human. A single distributing syringe avoids the use of a fresh supply vial for the charging of each receiving syringe, lessening the losses of excess volumes of the liquid that remain in the supply vials.
