Abstract

A double syringe delivery system is disclosed for holding a pair of syringes in a manner so as to accommodate the simultaneous activation of the plunger of each syringe in order to effect simultaneous delivery of the contents of each syringe. The double syringe delivery system includes an elongated support member that is placed between the barrel of each syringe. The elongated support member has resilient, C-shaped clamps on opposite sides of the support member. The clamps are used for holding the syringe barrels of both syringes so that the syringe barrels will be held together in a parallel manner. Further, elongated support member and clamps hold the syringe barrels in a fashion that is slightly longitudinally offset from one another to permit the two syringe barrels to be held together as closely as possible. An interconnecting bridge member connects the two syringe plungers so that they can also be simultaneously activated even though they are also slightly longitudinally offset from one another.

Claims

1. In a double syringe system wherein each syringe is comprised of a syringe barrel, a plunger and a delivery tip having an elongated, flexible delivery tube, a syringe delivery system for holding the syringes in a manner so as to accommodate simultaneous activation of the plunger of each syringe in order to effect simultaneous delivery of the contents of each syringe barrel, the delivery system comprising:

first locking means for locking the syringe barrels together in a parallel relationship wherein the barrels are as close together as possible, but are still parallel, and wherein the barrels are also locked in a manner so that they are slightly longitudinally offset from one another; and

second locking means for locking the plungers together in a parallel relationship and wherein the plungers are also locked in a manner so that they are longitudinally offset by an amount that is the same as the longitudinal offset of the syringe barrels.

2. A syringe delivery system as defined in claim 1, wherein each syringe is further comprised of a luer connector for attaching the delivery tip at one end of the syringe barrel, and a support disc at the other end of the syringe barrel, and wherein the first locking means comprises:

an elongated support member interposed between the syringe barrels so as to space them from one another;

first collar means on one side of the support member for attachment of the support member to one syringe at the luer connector and at the support disc of said one syringe so as to prevent axial movement of the one syringe relative to the support member; and

second collar means on an opposite side of the support member for attachment of the support member to the other syringe at the luer connector and at the support disc of said other syringe so as to prevent axial movement of the other syringe relative to the support member.

3. A syringe delivery system as defined in claim 2, wherein the support member has a width sized so as to space the syringes as close as possible, such that the disc of one syringe overlaps the disc of the other syringe.

4. A syringe delivery system as defined in claim 3, wherein one of the first and second collar means comprises spacer means for longitudinally offsetting one syringe from another so as to permit the overlapping relationship of the syringe discs.

5. A syringe delivery system as defined in claim 2, wherein each said collar means comprises a first resilient C-shaped clamp that can be removeably snapped onto a syringe barrel so as to abut the disc of the syringe barrel, and a second C-shaped clamp that can be removably snapped onto a syringe barrel and longitudinally spaced from the first clamp so as to abut the luer connector of the syringe barrel when snapped into place.

6. A syringe delivery system as defined in claim 4, wherein the elongated support member, first and second collar means and the spacer means are all formed as a single, unitary piece.

7. A syringe delivery system as defined in claim 1, wherein each syringe plunger has a push flange at a proximal end thereof, and wherein the second locking means is seated on the push flange of each syringe plunger and comprises means for joining the push flange of one plunger to the push flange of the other plunger.

8. A syringe delivery system as defined in claim 1, wherein each plunger is a cylindrical member with a hollow interior, and wherein the second locking means comprises:

a first post adapted for insertion into the interior of one plunger;

a second post adapted for insertion into the interior of the other plunger; and

an interconnecting bridge member joined to the two posts.

9. A syringe delivery system as defined in claim 8, wherein the bridge member is notched on one side thereof so as to accommodate the amount by which the plungers are vertically offset.

10. A syringe delivery system as defined in claim 1, further comprising retainer means for joining the flexible delivery tubes together at their distal ends.

11. A syringe delivery system as defined in claim 10 further comprising cap means tethered to the retainer means for selectively capping the distal ends of the delivery tubes.

12. In a double syringe system wherein each syringe is comprised of a syringe barrel having a luer connector at one end thereof and a support disc at the other end thereof, a plunger slidably situated in the syringe barrel and a delivery tip attached at the luer connector and having an elongated flexible delivery tube, a syringe delivery system for holding the syringes in a manner so as to accommodate simultaneous activation of the plunger of each syringe in order to effect simultaneous delivery of the contents of each syringe barrel, the delivery system comprising:

an elongated support member interposed between the syringe barrels so as to space them from one another;

first collar means on one side of the support member for attachment of the support member to one syringe at the luer connector and at the support disc of said one syringe so as to prevent axial movement of the one syringe relative to the support member;

second collar means on an opposite side of the support member for attachment of the support member to the other syringe at the luer connector and at the support disc of said other syringe so as to prevent axial movement of the other syringe relative to the support member, and wherein one of said first and second collar means comprise spacer means for longitudinally offsetting the syringes from one another so as to permit the discs at the ends of each syringe barrel to overlap one another, thereby locking the syringe barrels together in a parallel relationship wherein the barrels are as close together as possible; and

interconnecting bridge means for locking the plungers together in a parallel relationship and wherein the plungers are also locked in a manner so that they are longitudinally offset by an amount that is the same as the longitudinal offset of the syringe barrels.

13. A syringe delivery system as defined in claim 12, wherein the elongated support member, first and second collar means and the spacer means are all formed as a single, unitary piece.

14. A syringe delivery system as defined in claim 13, wherein each said collar means comprises a first resilient C-shaped clamp that can be removeably snapped onto a syringe barrel so as to abut the support disc of the syringe barrel, and a second C-shaped clamp that can be removably snapped onto the same syringe barrel and longitudinally spaced from the first clamp so as to abut the luer connector of the syringe barrel when snapped into place.

15. A syringe delivery system as defined in claim 14, wherein each syringe plunger has a push flange at a proximal end thereof, and wherein the second locking means is seated on the push flange of each syringe plunger and comprises means for joining the push flange of one plunger to the push flange of the other plunger.
