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 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,

the first and second syringes are configured to maintain respective volumes of the first and second fluids at a predetermined volumetric ratio;

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

based on the predetermined volumetric ratio, 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 one of the first and second flows is an atomized flow and the other one of the first and second flows is a non-atomized flow.

2. The method of claim 1, further comprising:

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

3. The method of claim 1, 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.

4. The method of claim 1, 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.

5. The method of claim 1, wherein the first fluid is platelet rich plasma and the second fluid is thrombin.

6. The method of claim 1, wherein the first and second fluids are dispensed at the volumetric ratio between approximately 1:

1 and 11;

1.

7. The method according to claim 1, wherein the first and second fluids are dispensed at the volumetric ratio greater than approximately 11:

1.

8. The method according to claim 1, wherein the first and second fluids are dispensed at the volumetric ratio less than approximately 1:

1.

9. A fluid delivery system for dispensing two separately maintained fluids to a treatment site of a patient, comprising:

a first syringe assembly maintaining a first fluid,

a second syringe assembly maintaining a second fluid,

the first and second syringes are configured to maintain respective volumes of the first and second fluids at a predetermined volumetric ratio;

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

based on the predetermined volumetric ratio, a first flow of the first fluid is dispensed 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 one of the first and second flows is an atomized flow and the other one of the first and second flows is a non-atomized flow.
