Abstract

Dispensing assemblies, methods, and kits of parts for dispensing two separate fluids to an treatment site, including entraining non-atomized flow of a first fluid in an atomized flow of a second fluid, delivering a first fluid upstream from a second fluid, delivering a first fluid and a second fluid with re-shapeable malleable tubes, delivering first and second fluids with releasable connectors maintained by a handle assembly, and kits of parts with angularly offset pockets.

Claims

1. A tip assembly for use in dispensing a first fluid maintained in a first syringe assembly and a second fluid maintained in a second syringe assembly to a treatment site of a patient, the tip assembly comprising:

a connecting element defining;

a first chamber configured to be in fluid communication with a first syringe assembly,

a second chamber configured to be in fluid communication with a second syringe assembly; and

a tip element including a nozzle and defining;

a first orifice extending from an origin to a terminal end, the origin in fluid communication with the first chamber,

a second orifice extending through the nozzle from an origin to a terminal end, the origin of the second orifice in fluid communication with the second chamber,

wherein the terminal end of the second orifice is formed in a plane differing from a plane of the terminal end of the first orifice.

2. The tip assembly of claim 1, wherein the connecting element defines an endwall including a plurality of channels formed therein, wherein the plurality of channels are in fluid communication with the first chamber and tangentially related to the origin of the first orifice.

3. The tip assembly of claim 1, wherein the terminal end of the first orifice is distally offset from the terminal end of the second orifice.

4. The tip assembly of claim 1, wherein the first orifice defines a first volume and the second orifice defines a second volume, the second volume greater than the first volume.

5. The tip assembly of claim 1, wherein the first orifice defines a length and the second orifice defines a length, the length of the second orifice greater than the length of the first orifice.

6. The tip assembly of claim 1, wherein extension of the first orifice to the terminal end thereof defines a first flow direction and extension of the second orifice to the terminal end thereof defines a second flow direction, the first flow direction angularly offset from the second flow direction.

7. The tip assembly of claim 6, wherein the first flow direction and the second flow direction intersect at a point distal the terminal end of the first orifice.

8. The tip assembly of claim 1, wherein the tip element further defines a third orifice, and further wherein the tip element is rotatable relative to the connecting element to selectively and fluidly couple the third orifice to one of the first chamber and the second chamber.

9. The tip assembly of claim 1, wherein the first orifice and the second orifice are configured to generate different flow patterns

10. A method of dispensing two separately maintained fluids to a treatment site of a patient, the method comprising:

providing a fluid delivery system including;

a first syringe assembly maintaining a first fluid,

a second syringe assembly maintaining a second fluid,

a tip element defining;

a first orifice extending to a terminal end, the first orifice in fluid communication with the first syringe assembly,

a second orifice extending to a terminal end, the second orifice in fluid communication with the second syringe assembly; and

dispensing a first flow of the first fluid from the terminal end of the first orifice into a second flow of the second fluid from the terminal end of the second orifice, wherein the first and second flows differ in flow type.

11. The method of claim 10, further comprising:

entraining a non-atomized flow of the second fluid in an atomized flow of the first fluid.

12. The method of claim 10, wherein dispensing the first and second fluids includes:

dispensing the first fluid from the terminal end of the first orifice in a first direction and the second fluid from the terminal end of the second orifice in a second direction, the first direction angularly offset from the second direction.

13. The method of claim 10, wherein dispensing the first and second fluids includes:

dispensing the first fluid as an atomized flow and the second fluid as a non-atomized flow.

14. The method of claim 10, wherein the first fluid is platelet rich plasma and the second fluid is thrombin.

15. The method of claim 10, wherein the first and second fluids are dispensed at a volumetric ratio between approximately 3:

1 and 10;

1.

16. A manifold assembly for use in fluid dispensing system for delivering two separately maintained fluids to a treatment site of a patient, the manifold assembly comprising:

a mating fixture coupleable to a first syringe assembly and a second syringe assembly;

a first tube including a flexible body, the first tube in fluid communication with the mating fixture and fluidly coupleable to a tip assembly having a first orifice for delivering a first fluid and a second orifice for delivering a second fluid; and

a second tube including a flexible body, the second tube in fluid communication with the mating fixture and fluidly coupleable to the tip assembly.

17. The manifold assembly of claim 16, wherein the first tube further includes a bendable member such that the first tube is semi-rigid.

18. A method of dispensing two separately maintained fluids to a treatment site of a patient, the method comprising:

providing a fluid dispensing system including,

a second tube including a flexible body, the second tube in fluid communication with the second connector and fluidly coupleable to the tip assembly;

cutting the first and second tubes to a desired length;

fluidly coupling the first tube and the tip assembly, such that the first tube is in fluid communication with the first orifice;

fluidly coupling the second tube and the tip assembly, such that the second tube is in fluid communication with the second orifice;

delivering the first fluid from the first syringe assembly, through the first tube, to the first orifice and the second fluid from the second syringe assembly, through the second tube, and to the second orifice.

19. The method of claim 18 further comprising:

bending the first tube from a first, independently maintained position to a second, independently maintained position.

20. A handle assembly for use in fluid delivery system for delivering two separately maintained fluids to a treatment site of a patient, the handle assembly comprising:

a latitudinal member extending from a first end to a second, opposing end and defining a centerline between the first and the second ends;
