Long stem syringe apparatus for dispensing compositions and related methods

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 including
• a 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 her having means for grasping the barrel located at the proximal grasping end of the barrel,
• a composition held within the chamber, and
• plunger 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, the plunger means having a length that is at least twice that of the chamber of the barrel such that when the plunger means is fully advanced within the chamber a portion of the plunger extends out of the chamber with a length that is at least equal to that of the chamber;
• 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;
• and
• continuously 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.

A method for dispensing a dental composition of two or more components from a syringe so that the syringe is grasped in a single position, the method comprising the steps of:

• obtaining a 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 for holding a composition, the barrel further having means for grasping the barrel located at the proximal grasping end of the barrel,
• delivering a dental composition having at least two components into the chamber via an opening at the top grasping end of the barrel,
• mixing the components of the dental composition in the chamber,
• obtaining plunger means for advancing the composition positioned within the barrel through the exit port at the first end of the barrel, wherein the plunger means has 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 ratio which is no less than about 1.5:1,
• inserting the distal lead end of the plunger means into the chamber to provide a syringe,
• 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,
• continuously delivering the dental 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.

A syringe for dispensing a composition, the syringe comprising:

• (a) a 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 for holding a composition,
• the barrel having an opening at the top grasping end for accessing the chamber and having an exit port at the bottom end for enabling the composition to exit the chamber, and
• means for grasping the barrel, the grasping means being located at the proximal grasping end of the barrel;
• and
• (b) plunger means for advancing the composition positioned within the barrel through the exit port at the bottom end of the barrel,
• wherein the plunger means has a distal lead end opposite from a proximal pushing end,
• wherein the plunger means has a length which when fully inserted into the barrel, extends sufficiently beyond the grasping means so as to enable a user to grasp the syringe in a single position with the proximal pushing end against the palm of the user's hand and the user's fingertips against the grasping means and to then continuously deliver a 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.
