Abstract:
A method for dispensing a composition from a syringe so that the syringe is grasped in a single position, the method comprising the steps of:obtaining a syringe includinga hollow elongated barrel having a sidewall extending between a top grasping end and an opposing bottom end, the sidewall having an interior surface defining a chamber, the barrel further having means for grasping the barrel located at the proximal grasping end of the barrel,a composition held within the chamber, andplunger means for advancing the composition positioned within the chamber out of the barrel, the plunger means having a distal lead end opposite from a proximal pushing end, and wherein the length of the plunger means relative to the length of the chamber yields a ration which is no less than about 1.5:1;grasping the syringe with the proximal pushing end of the plunger means against the palm of the user's hand and with the user's fingertips against the grasping means; andcontinuously delivering the composition from the chamber by advancing the plunger means within the chamber until the distal lead end of the plunger means contacts the bottom end of the chamber through pulling the grasping means while pushing the proximal pushing end against the user's palm, without regrasping the syringe such that the syringe is not moved relative to a delivery site during the delivery of the composition to the delivery site due to movement of the user's hand.
