Abstract
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 Analysis
Total Claims: 9
Claim 1
Independent Claim
175 words
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.
Claim 2
Dependent Claim
175 words
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.
Claim 3
Dependent Claim
23 words
The apparatus of claim 1, further comprising means for filtering the compressed air signal before the signal is transmitted for said regulating means.
Claim 4
Dependent Claim
18 words
The apparatus of claim 2 wherein said filtering means comprises a sub-micron filter interposed in said transmitting means.
Claim 5
Dependent Claim
15 words
The apparatus of claim 3, wherein said sub-micron filter comprises a 0.2 micron bacteria filter.
Claim 6
Dependent Claim
41 words
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.
Claim 7
Dependent Claim
23 words
The apparatus of claim 1, further comprising means for filtering the compressed air signal before the signal is transmitted to said regulating means.
Claim 8
Dependent Claim
18 words
The apparatus of claim 5, wherein said filtering means comprises a sub-micron filter interposed in said transmitting means.
Claim 9
Dependent Claim
15 words
The apparatus of claim 7, wherein said sub-micron filter comprises a 0.2 micron bacterial filter.
