Abstract

The disclosure relates to an extended-range spray applicator, and methods of making and use thereof, for dosing vaccines and/or probiotics to avian animals at a distance.

First claim

What is claimed:

1. An extended-range spray applicator comprising:
an air supply,
primary shroud mounted on and in fluid communication with the air supply,
a liquid atomizer mounted on the air supply, and;
a secondary shroud detachably positioned between the primary shroud and the liquid atomizer, and wherein the liquid atomizer is laterally adjustable with respect to the air supply.

2. The spray applicator of claim 1 , wherein the primary and secondary shrouds comprise slots through which one or more extenders pass.

3. The spray applicator of claim 2 , wherein the atomizer is fixedly connected to the one or more extenders.

4. The spray applicator of claim 2 , wherein the atomizer is adjustably connected to the one or more extenders, such that a user may direct the atomizer upward or downward, with respect to the direction of air flow.

5. The spray applicator of claim 1 , wherein the liquid atomizer being laterally adjustable with respect to the air supply allows a user to position the atomizer such that it is either nearer to, or farther from, the air supply.

6. The spray applicator of claim 1 , wherein both the primary and secondary shrouds comprise a plurality of spacers, which are configured to allow the shrouds to be reversibly connected to one another.

7. The spray applicator of claim 6 , wherein each shroud comprises 4 spacers.

8. The spray applicator of claim 1 , wherein the air supply comprises an adapter that is cylindrical and comprises a means for lockably attaching a head assembly to an air supply portion of the spray applicator.

9. The spray applicator of claim 8 , further comprising a battery housing, situated atop the head assembly, and configured to receive and house a rechargeable battery, which supplies electricity to an atomizer motor.

10. The spray applicator of claim 1 , wherein the liquid atomizer is a rotary disc atomizer, which is mechanically connected to a disc atomizer motor, which is housed within a motor housing, which is fixedly connected to a disc atomizer assembly frame.

11. The spray applicator of claim 8 ,
wherein the liquid atomizer comprises a rotary disc atomizer, for transforming liquid into sub-millimeter-sized droplets; wherein the rotary disc atomizer is situated centrally within the primary and secondary shrouds;
at least two extenders, for attaching the rotary disc atomizer to the head assembly;
a motor, mechanically connected to the rotary disc atomizer; and
a battery receptacle, for holding a battery, which is electrically connected to the motor.

12. The spray applicator of claim 11 , wherein the secondary shroud has a conical angle of about 30°.

13. The spray applicator of claim 11 , wherein at least one shroud is characterized by having at least three diameters, D1, D2 and D3, and at least two angles, A1 and A2.

14. The spray applicator of claim 13 , wherein D1 is at least about 30% to about 50% smaller than D2; and wherein D2 is about equal to or is about 10% smaller than D3.

15. The spray applicator of claim 14 , wherein A1 is between about 90° and about 145°; and wherein A2 is between about 130° and 160°.
