Abstract
A kit is disclosed for accurately loading a small volume dose of a medication within a syringe and for delivering the small volume dose of the medication at a treatment site. The kit generally includes a loading and delivery system in accordance herewith, a syringe, and a medication. The loading and delivery system includes a syringe delivery ring and a syringe loading guide, which may be used for example, to administer a small volume dose of a medication at the end of an ocular surgery.
Claims16
A kit for accurately loading a small volume dose of medication within a syringe and for delivering the small volume dose of medication at a treatment site, the kit comprising:
- a syringe including a plunger and a barrel for holding a medication, the plunger including a plunger rod, a plunger flange at a proximal end of the plunger rod and a plunger seal at a distal end of the plunger rod, wherein the barrel includes a barrel flange at a proximal end of the barrel and wherein the barrel is sized to receive a length of the plunger rod and the plunger seal therein;
- a syringe delivery ring including a lumen and a sidewall opening that extend from a proximal end to a distal end thereof, the sidewall opening being configured to permit the plunger rod of the syringe to traverse the sidewall opening and to be slidably received within the lumen of the syringe delivery ring to thereby couple the syringe delivery ring to the plunger rod, and the syringe delivery ring further including a proximal segment and a distal segment, wherein the proximal segment has a smaller outer diameter than the distal segment and the distal segment has a proximal-facing bearing surface;
- and
- a syringe loading guide including a proximal-facing surface for abutting with the plunger flange of the syringe during loading, a distal-facing surface for abutting with the proximal-facing bearing surface of the distal segment of the syringe delivery ring during loading, and a coupling archway configured to attach to the proximal segment of the syringe delivery ring during loading, wherein a first height of the syringe loading guide is greater than a second height of the proximal segment of the syringe delivery ring;
- and
- a medication for loading within and for delivery by the syringe, wherein a difference between the first height of the syringe loading guide and the second height of the proximal segment of the syringe delivery ring corresponds to a distance the plunger seal travels within the barrel of the syringe to deliver a small volume dose of the medication.
A loading and delivery system for use with a syringe to accurately load a small volume dose of medication within the syringe and to deliver the small volume dose from the syringe at a treatment site, the system comprising:
- a syringe delivery ring including a lumen and a sidewall opening that extend from a proximal end to a distal end thereof, the sidewall opening being configured to permit a plunger rod of the syringe to traverse the sidewall opening and to be slidably received within the lumen of the syringe delivery ring to thereby couple the syringe delivery ring to the plunger rod, and the syringe delivery ring further including a proximal segment and a distal segment, wherein the proximal segment has a smaller outer diameter than the distal segment and the distal segment has a proximal-facing bearing surface;
- and
- a syringe loading guide including a proximal-facing surface configured to abut with a plunger flange of the plunger rod of the syringe during loading, a distal-facing surface configured to abut with the proximal-facing bearing surface of the distal segment of the syringe delivery ring during loading, and a coupling archway that is configured to attach to the proximal segment of the syringe delivery ring during loading, wherein a first height of the syringe loading guide is greater than a second height of the proximal segment of the syringe delivery ring, and
- wherein when the system is coupled to the syringe, with the syringe loading guide attached to the syringe delivery ring whereby the proximal segment of the syringe delivery ring is received within the coupling archway of the syringe loading guide with the distal-facing surface of the syringe loading guide in abutment with the proximal-facing bearing surface of the distal segment of the syringe delivery ring, a distance between the proximal-facing surface of the syringe loading guide and the proximal end of the syringe delivery ring corresponds to the small volume dose of medication to be delivered from the syringe.
