Abstract
A method of treatment may include providing a syringe having medicinal fluid therein for administering to a patient and coupling an attachment portion of an extrusion accessory having a handle and a pawl to a flange portion of the syringe. The pawl may have first and second ends, and be hingedly and rotatably coupled relative to the handle at a first position at the first end and at a second position between the first and second ends. The method may further include applying a force to translate the handle in a direction substantially perpendicular relative to a longitudinal axis of the syringe to cause axial movement of the second end of the pawl. The second end of the pawl may be engaged with a plunger of the syringe and axial movement of the second end of the pawl may drive the plunger forward to extrude the medicinal fluid from the syringe.
