Abstract
A fluid delivery system where two reactive fluids are delivered simultaneously and separately from a pair of syringes to a delivery site. In one embodiment, a length of tubing exits one syringe and passes through a cannula exiting from the other syringe, to deliver both fluids, separately, but in a controlled volume and space to the delivery site. Alternately, the fluids can mix within the cannula, but its configuration prevents clogging at the delivery site.

TWO COMPONENT SYRINGE DELIVERY SYSTEM
M ELD OF THE INVENTION
This invention relates to a system for delivery of two separate components. More specifically, this invention relates to a system for delivery of two separate components by syringe, where the components are mixed at the site of delivery. Most specifically. this invention relates to the delivery of two components by syringe where the components are mixed at the site of delivery and the components are delivered along generally equivalent path lengths.
BACKGROUND OF THE INVENTION
In the medical field, it may be desired to deliver two separate components to an active medical site. For instance, in the production of fibrin glue, it is desirable to deliver thrombin and fibrinogen to the same delivery site. As with the case in the formation of fibrin glue, it may be desirable to deliver the two components simultaneously and separately so that they only mix at the delivery site. For instance, with fibrin glue formation, if the components are delivered and mixed within a delivery system and then delivered to the delivery site, it is possible to clog the delivery system due to the adhesive nature of fibrin glue. On the other hand, other systems may need mixing at some point within the delivery tube. Of course. clogging of this tube is undesirable.
Previous attempts at mixing the separate chemicals in a delivery system at the delivery site have met with J&J-1305 little success. Therefore, common delivery systems may contain the improper mixture ratio of components, or have components mined within the delivery system and then delivered, albeit over a short path length, to the delivery site. Devices which have attempted simultaneous delivery have been lacking in mechanisms for proper attachment of the delivery tubes. When these tubes clog, forces may cause the delivery tubes to separate from the syringe. Furthermore, systems where mixture is made at the delivery site are very difficult to manipulate.
Frequent clearing of clogged components is necessary.
Certainly, these present systems have all been virtually impossible to operate with one hand.
Finally, none of the typical two component delivery systems, regardless of the location of the mixture of the two components, have been capable of operating with typical hypodermic syringes locked in place within a sturdy. lightweight. and functional locking mechanism that ensures simultaneous delivery of both separate components in the delivery system. The two component delivery systems have been either too bulky to deliver the two components adequately, or too flimsy to hold the typical hypodermic syringes. Because these systems operate with one hand, they are hard to formulate within a convenient package.
~ummar~r of the Invention Therefore. it is an object of the invention to provide a two component delivery system where the components are delivered at the delivery site simultaneously and separately.
It is further an object of the invention to provide a J&J-1305 2~~~6~~

It is further an object of the invention to provide a J&J-1305 2~~~6~~
two component delivery system where the components are delivered separately and simultaneously to the delivery site along a single cannula.
Another object of the invention is to provide a delivery system which prevents clogging of mixed fluids by having the fluids come into contact near the exit port and toward the delivery site.
It is further an object of the invention to provide a two component syringe delivery system where the single cannula of the invention is adaptable for use with two typical hypodermic syringes.
It is yet another object of the invention to provide a two component syringe delivery system where the syringes in the system can be managed and held in place securely by a holder which allows for simultaneous delivery of the two components through equivalent pressures on the two syringes.
It is a final object of the invention to provide a two component syringe delivery system in which clogging is prevented along the entire length of the fluid paths of both components by preventing mixture of the two components until both components have exited the system, so that mixture is obtained at the delivery site.
These and other objects of the invention are accomplished in a system whereby two typical hypodermic syringes can be locked in place within a syringe holder to provide uniform delivery of the two components. The syringe holder is formed such that the syringes are insertable through the holder itself and then locked in place along a channeled upper surface to prevent movement J&J-1305 ~Q~~~ ~2 of either syringe. In addition, a plunger clip is inserted over the plungers of the syringes so that pressure can be equally distributed to both syringes during operation of the system.
The locked syringes are then attached via luer lock fittings to a double tubing system. The tubes are attached so that they both reach the delivery site along roughly equivalent path lengths, so that the mixture of the two components can by made at the delivery site.
Alternately, the two components are delivered into an assembled luer attachment which comprises a double luer (or luer lock) fitting attachable to both syringes. Within the syringes, there is described a double fluid path so that the fluids run parallel to each other at the exit of the luer attachment. At the attachment exit, there is insertable a single cannula. Projecting from the attachment is a length of tubing containing one of the elements. This tubing fits within the cannula so that one element travels the length of the cannula without contacting the cannula, down the length of the tubing. The other element exits the attachment and is forced around the tubing through the length of the cannula.
The elements mix at or near the exit from the cannula, the first element exiting through the tubing and the second element exiting from the cannula and around the tubing.
Again, the element mix at or near the delivery site, and any reactive material is easily ejected from the large diameter cannula.
According to a broad aspect of the present invention there is provided a system for simultaneous delivery of fluids from two syringes. The system comprises an attachment containing a pair of luer-type connectors for luer connection to each of the syringes. Each of the luer connection has attached to it a fluid path. One of the path exits from the attachment at a luer hub, while the other of the path exits from the attachment in a length of tubing. A single cannula is provided for luer attachment to the luer hub. The tubing fits within the cannula.
According to a still further broad aspect of the present invention there is provided for use with two syringes, each said syringe having a diameter, a pair of ears and a plunger for firing said syringe, a holder for locking said syringes together, said holder comprising a pair of flanges separated by an arm, each said flange having a pair of holes, one hole on each said flange corresponding to one syringe diameter and one hole on each said flange corresponding to the opposite syringe diameter, each said corresponding hole on each flange aligned on one side of said arm, such that when said syringes are passed through said holes such that each said syringe is aligned with one of said pair of holes, said syringes are fixed relative to one another, and further comprising an attachment containing a pair of luer-type connectors for luer connection to each of said syringes, each said luer connection having attached to it a fluid path, one said path exiting from said attachment at a luer hub, the other said path exiting from said attachment in a length of tubing; and a single cannula for luer attachment to said luer hub, said tubing fitting within said cannula.

For instance, in one syringe there may be fibrinogen, and in an alternate syringe there may be thrombin. The combination will be mixed together at the delivery site for the formation of fibrin glue.
The first component of the delivery system to be J&J-1305 2Q~~~7~
discussed is the holding mechanism 100 which assures proper delivery of the two components simultaneously. In the present holder 100, there are located bored holes 105a, 105b and 106a, 106b, for both syringes and two sets of flanges 110, 120 for locking, separated by arm 115.
The lower set of flanges 120a, 120b. keep the syringes 10, 20 in place from rotating around the upper set of flanges 110a, 110b. The upper flanges 110a, 110b ensure that the two syringes 10. 20 remain in desired position.
Located in the upper flanges 110a, 110b are channels 130a, 130b which form a locking mechanism for the syringes. On the syringes 10, 20 there are ears 12a, 12b and 22a, 22b, which are usually gripped during individual operation of the syringes. These ears 12a, 12b, 22a, 22b, can be incorporated into channels 130a. 130b by first inserting the syringes 10, 20 into the sets of holes 105, 106 and then rotating the ears of the syringes into channels 130a, 130b, as with locked syringe 20 in Fig. 1.
When locked in place, both syringes 10, 20 are fined in parallel or at an angle and can be given the appropriate amount of pressure to deliver simultaneously the two components of the system. When angled, the syringes 10. 20 provide uniform mining of the two components and can be used in a spray which mites either at or near the delivery site. Simultaneous delivery is accomplished by the placement of plunger clip 140 at the plunger heads 15, 25 of the two syringes 10, 20. It is to be noticed that the clip 140 itself has channeled grooves 192, 144 which fit along the outer diameters of the heads 15, 25 of the two syringes 10. 20, so that the heads 15, 25 are positioned at the desired angle along the entire fluid paths. Heads 15, 25 are able to move within the clip 140 so that depression of both syringes 10, 20 is J&J-1305 ~02~67~
accomplished simultaneously.
Thus, the user grasps the syringes with the thumb crossing the length of cap 140, the palm bridging the length of syringes 10, 20 and the index and third finger holding the holder 100 across the flanges 110x, 110b. By forcing the thumb on the cap 140, equivalent pressures are provided to both syringes 10, 20. and equivalent amounts of fluid are delivered from both syringes 10, 20.
As further seen in Figure 2, exiting syringes 10. 20 there are luer lock fittings 38, 48 which can be attached to the luer lock hubs 18, 28 of both syringes 10, 20.
These luer lock fittings 38, 48 are attached at their opposite ends to flexible vinyl tubing 35, 45 forming a double cannula. Flexible tubing allows rotation of the luer lock fittings 38, 48. This double cannula is joined so that the dual cannula tubings 35, 45 are attached at the ends. usually with solvent adhesive. Thus. when the equivalent amounts of pressure are provided, the dual cannula 35, 45 is able to deliver the same amount of fluid from each syringe 10, 20. These cannulas will generally have outer diameters of about .060" and inner diameters of about .020", with lengths anywhere from 1" to 5". Because the tubings 35. 45 are cut off at equivalent lengths, there is simultaneous delivery of fluid from both syringes.
Alternately, a single cannula solution is found in Figures 3-5. There is shown connector 200 which has a double luer fitting 208, 218. This fitting 208, 219 may be a general or luer lock fitting. This connector 200 contains hollowed double fluid path 209, 219 which is formed from tubing or plastic molding. At the end of the double fluid path 209, 219 there is luer hub 220.
Attached through luer hub 220 is fluid path 219, which J&J-1305 _ g _ allows the fluid from syringe 20 to flow directly through the hub 220. Fluid in first path 209 is deposited into hub 220. Thus, the central portion of hub 220 can be filled with fluid from syringe 10.
Single cannula fitting 240 has a cannula 242 extending from it so that cannula 242 would allow approximately twice the volume of fluid as compared to fluid path 219. When single cannula 240 is fit within the luer hub 220, therefore, equivalent volumes of the fluid from syringe 10 travel the length of the cannula 242 half filled with fluid path 219, with equivalent volumes of the fluid from syringe 20 flowing through the fluid path 219.
Again, equivalent volumes of both fluids reach the end of the cannula 242 simultaneously. Mixing can take place outside the cannula 242 so that clogging is prevented along the cannula 242.
In addition, fluid path 219 may end at some point near the end of cannula 242, so that mixing occurs just before the delivery site. Reacted materials are easily ejected from cannula 242 since its diameter is larger than either of paths 209, 219.
Thus, with the two component delivery system, equivalent pressures are derived and these equivalent pressures are able to provide for equivalent amounts of fluid flowing the length of the system. When the equivalent amounts of fluid are ejected from the system, they are able to mix at the delivery site so that clogging is prevented in the system. In addition, chemical reactions can take place outside the cannula, or pre-miz before delivery without clogging as desired. Finally, the entire system is able to provide the proper amounts of fluid directly to the delivery site.

These and other objects of the present invention are to be determined from the attached claims and their equivalents.
J&J-1305
The lower set of flanges 120a, 120b. keep the syringes 10, 20 in place from rotating around the upper set of flanges 110a, 110b. The upper flanges 110a, 110b ensure that the two syringes 10. 20 remain in desired position.
Located in the upper flanges 110a, 110b are channels 130a, 130b which form a locking mechanism for the syringes. On the syringes 10, 20 there are ears 12a, 12b and 22a, 22b, which are usually gripped during individual operation of the syringes. These ears 12a, 12b, 22a, 22b, can be incorporated into channels 130a. 130b by first inserting the syringes 10, 20 into the sets of holes 105, 106 and then rotating the ears of the syringes into channels 130a, 130b, as with locked syringe 20 in Fig. 1.
When locked in place, both syringes 10, 20 are fined in parallel or at an angle and can be given the appropriate amount of pressure to deliver simultaneously the two components of the system. When angled, the syringes 10. 20 provide uniform mining of the two components and can be used in a spray which mites either at or near the delivery site. Simultaneous delivery is accomplished by the placement of plunger clip 140 at the plunger heads 15, 25 of the two syringes 10, 20. It is to be noticed that the clip 140 itself has channeled grooves 192, 144 which fit along the outer diameters of the heads 15, 25 of the two syringes 10. 20, so that the heads 15, 25 are positioned at the desired angle along the entire fluid paths. Heads 15, 25 are able to move within the clip 140 so that depression of both syringes 10, 20 is J&J-1305 ~02~67~
accomplished simultaneously.
Thus, the user grasps the syringes with the thumb crossing the length of cap 140, the palm bridging the length of syringes 10, 20 and the index and third finger holding the holder 100 across the flanges 110x, 110b. By forcing the thumb on the cap 140, equivalent pressures are provided to both syringes 10, 20. and equivalent amounts of fluid are delivered from both syringes 10, 20.
As further seen in Figure 2, exiting syringes 10. 20 there are luer lock fittings 38, 48 which can be attached to the luer lock hubs 18, 28 of both syringes 10, 20.
These luer lock fittings 38, 48 are attached at their opposite ends to flexible vinyl tubing 35, 45 forming a double cannula. Flexible tubing allows rotation of the luer lock fittings 38, 48. This double cannula is joined so that the dual cannula tubings 35, 45 are attached at the ends. usually with solvent adhesive. Thus. when the equivalent amounts of pressure are provided, the dual cannula 35, 45 is able to deliver the same amount of fluid from each syringe 10, 20. These cannulas will generally have outer diameters of about .060" and inner diameters of about .020", with lengths anywhere from 1" to 5". Because the tubings 35. 45 are cut off at equivalent lengths, there is simultaneous delivery of fluid from both syringes.
Alternately, a single cannula solution is found in Figures 3-5. There is shown connector 200 which has a double luer fitting 208, 218. This fitting 208, 219 may be a general or luer lock fitting. This connector 200 contains hollowed double fluid path 209, 219 which is formed from tubing or plastic molding. At the end of the double fluid path 209, 219 there is luer hub 220.
Attached through luer hub 220 is fluid path 219, which J&J-1305 _ g _ allows the fluid from syringe 20 to flow directly through the hub 220. Fluid in first path 209 is deposited into hub 220. Thus, the central portion of hub 220 can be filled with fluid from syringe 10.
Single cannula fitting 240 has a cannula 242 extending from it so that cannula 242 would allow approximately twice the volume of fluid as compared to fluid path 219. When single cannula 240 is fit within the luer hub 220, therefore, equivalent volumes of the fluid from syringe 10 travel the length of the cannula 242 half filled with fluid path 219, with equivalent volumes of the fluid from syringe 20 flowing through the fluid path 219.
Again, equivalent volumes of both fluids reach the end of the cannula 242 simultaneously. Mixing can take place outside the cannula 242 so that clogging is prevented along the cannula 242.
In addition, fluid path 219 may end at some point near the end of cannula 242, so that mixing occurs just before the delivery site. Reacted materials are easily ejected from cannula 242 since its diameter is larger than either of paths 209, 219.
Thus, with the two component delivery system, equivalent pressures are derived and these equivalent pressures are able to provide for equivalent amounts of fluid flowing the length of the system. When the equivalent amounts of fluid are ejected from the system, they are able to mix at the delivery site so that clogging is prevented in the system. In addition, chemical reactions can take place outside the cannula, or pre-miz before delivery without clogging as desired. Finally, the entire system is able to provide the proper amounts of fluid directly to the delivery site.
