Abstract

Apparatus for typically delivering a measured quantity of liquid to a small animal comprising:

a spray nozzle for producing an atomized stream of liquid;

a syringe in fluid communication with the spray nozzle for delivering a measured quantity of the liquid from a liquid source to the spray nozzle;

means for actuating the syringe to deliver the measured quantity of liquid activated by a compressed air signal from a compressed air source;

means for regulating the compressed air signal to deliver to the spray nozzle a portion of the compressed air signal for atomizing the measured quantity of liquid; and

means for transmitting the compressed air signal simultaneously to the actuating means and to the regulating means.

Claims

1. A spray apparatus for topically delivering a measured quantity of liquid to a small animal being simultaneously subcutaneously injected on an automatic injection apparatus which provides a compressed air signal essentially simultaneously with the injection, said spray apparatus comprising:

a spray nozzle means for producing an atomized stream of liquid for topical delivery to the small animal;

a syringe in fluid communication with the spray nozzle means for delivering a measured quantity of the liquid from a liquid source to said spray nozzle means, said syringe adapted for connection to the liquid source;

means for actuating said syringe to deliver the measured quantity of liquid in response to receipt of said compressed air signal from the automatic injection apparatus;

means for regulating the compressed air signal so as to deliver to said spray nozzle means a portion of said compressed air signal for atomizing the measured quantity of liquid; and

means for transmitting the compressed air signal from pneumatic circuitry in the automatic injection apparatus simultaneously to said actuating means and to said regulating means.

2. The apparatus of claim 1, further comprising means for filtering the compressed air signal before the signal is transmitted for said regulating means.

3. The apparatus of claim 2 wherein said filtering means comprises a sub-micron filter interposed in said transmitting means.

4. The apparatus of claim 3, wherein said sub-micron filter comprises a 0.2 micron bacteria filter.

5. The apparatus of claim 1, further comprising an outside covering means for encasing said nozzle means, said syringe, said actuating means and said regulating means and a retaining plate means attached to the outside covering means for removably mounting said syringe.

6. The apparatus of claim 1, further comprising means for filtering the compressed air signal before the signal is transmitted to said regulating means.

7. The apparatus of claim 5, wherein said filtering means comprises a sub-micron filter interposed in said transmitting means.

8. The apparatus of claim 7, wherein said sub-micron filter comprises a 0.2 micron bacterial filter.
