Abstract

An atomizer delivery manifold or spray head with an adjustable spray pattern tip is provided. The adjustable spray pattern atomizer is especially useful for delivery of fibrin glues, and enables a fluid admixture to be applied precisely to a specific site in a wide range of spray patterns.

Claims

1. An atomizer delivery manifold comprising an adjustable spray pattern tip in mating relationship and in fluid communication with a distal end of a manifold, the tip having an aperture through which fluids are dispensed, the tip being adjustable to control the spray pattern angle of the fluids emanating therefrom by movement of the tip with respect to the manifold.

2. The manifold of claim 1, wherein the spray tip is rotatable to adjust the spray angle of the spray.

3. The manifold of claim 2, wherein the spray tip is reciprocatable to adjust the spray angle of the spray.

4. The manifold of claim 2, wherein the tip has an external manipulating portion to facilitate movement and positioning of the tip.

5. The manifold of claim 3, wherein the tip has an external manipulating portion to facilitate movement and positioning of the tip.

6. The manifold of claim 2, wherein the spray tip is threadly attached to the manifold and the manipulating portion includes gripping projections to facilitate rotation of the tip.

7. The manifold of claim 3, wherein the spray tip includes a sleeve portion and the manipulating portion is a flange, grippable to facilitate back and forth motion of the tip.

8. An adjustable spray head tip for a spray head assembly, the tip having an aperture through which fluids are atomized, and an external manipulating portion to facilitate movement of the tip wherein the tip is tightened or loosened within the spray head assembly, and the fluid pressure at the tip is varied, and thereby varying the pattern of spray of the fluids through the spray tip.

9. The spray tip of claim 8 further comprising an external manipulating portion which facilitates movement and positioning of the tip.

10. The spray tip of claim 9, wherein the external manipulating portion facilitates a rotation motion of the tip with respect to the spray head.

11. The spray tip of claim 9, wherein the external manipulating portion facilitates a back and forth movement of the tip with respect to the spray head.

12. A method of spraying fibrin glues, comprising:

delivering components of the fibrin glue to a spray head having a mixing chamber and a spray tip in fluid communication with a manifold;

mixing the components in the manifold chamber to form an admixed product;

delivering the admixed product to the spray tip, the spray tip having an discharge aperture,

varying the pattern of spray for the admixed product by moving and positioning the tip relative to the manifold; and

discharging the admixed product through the aperture to a biological surface.

13. A spray atomizer system for delivering a fluid mixture in varying spray patterns, comprising:

a manifold having conduits for receiving fluids and a mixing chamber for receiving and mixing the fluids,

a gas channel for receiving gas or air for mixing the fluids in the mixing chamber, and

a spray tip coupled to the manifold through which the fluids are atomized into a spray, the tip being adjustable to control the spray pattern angle of the fluids emanating therefrom by movement and positioning of the tip with respect to the manifold, the tip having an external manipulating portion to facilitate movement and positioning of the tip.

14. The system of claim 13, wherein the tip is threadly attached to the manifold and rotation of the tip moves the tip with respect to the manifold.

15. The system of claim 13, wherein the tip is a linear member capable of reciprocating motion so as to move the tip with respect to the manifold.

16. A device for applying fibrin glues or sealants, comprising:

commonly actuable reservoirs for each component of a fibrin sealant,

a source of gas,

a mixing chamber for receiving and mixing the components and gas to form a sealant mixture, and

an adjustable spray pattern spray head for directing a spray of sealant mixture in a pattern, the spray head having a spray head tip and a discharge aperture therethrough, the tip being matedly engaged with the mixing chamber and adjustable to control the spray pattern angle of the fluids emanating therefrom by movement and positioning of the tip with respect to the mixing chamber, the tip having an external manipulating portion to facilitate movement of the tip.
