Abstract
Abstract Apparatus for aspirating and irrigating the rumen of a cow includes a nozzle connected to one end of a flexible tube and adapted to be slid down the cow's throat and inserted into the rumen. The other end of the tube is connected to a container which is adapted to be placed in a vacuumized condition by a hand-operated suction pump. When the pump is operated, toxic liquid and food in the cow's rumen is sucked into the nozzle, through the tube and into the container. A second tube is located in the first tube and is adapted to eject a spray of water for cleaning the nozzle and for irrigating the rumen. The water is contained in a tank which may be pressurized by compressed air at a veterinarian's office.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
220 words
Apparatus for aspirating and irrigating an organ of a non-human mammal, said apparatus comprising a nozzle shaped for insertion into the organ and having a plurality of ports, a first flexible tube having one end portion communicating with said nozzle, a first portable container for holding an opposite end portion communicating with said container, a suction pump communicating with said container and selectively operable to create a negative pressure in said container, said tube and said nozzle thereby to suck material from said organ into said ports and said nozzle, through said tube, and into said container, a second flexible tube located within said first tube and having one end portion communicating with said nozzle, a second portable container adapted to hold a liquid for irrigating said organ, said second tube having an opposite end portion communicating with said second container, means within said first container for establishing communication between said second container and said opposite end of said second tube, and means on said second container for admitting pressure fluid into said second container for the purpose of pressuring said second container in order to force said liquid out of said second container, through said second tube and said nozzle, and out of said ports so as to remove clogged material from said ports and to irrigate said organ.
Claim 2
Dependent Claim
220 words
Apparatus for aspirating and irrigating an organ of a non-human mammal, said apparatus comprising a nozzle shaped for insertion into the organ and having a plurality of ports, a first flexible tube having one end portion communicating with said nozzle, a first portable container for holding an opposite end portion communicating with said container, a suction pump communicating with said container and selectively operable to create a negative pressure in said container, said tube and said nozzle thereby to suck material from said organ into said ports and said nozzle, through said tube, and into said container, a second flexible tube located within said first tube and having one end portion communicating with said nozzle, a second portable container adapted to hold a liquid for irrigating said organ, said second tube having an opposite end portion communicating with said second container, means within said first container for establishing communication between said second container and said opposite end of said second tube, and means on said second container for admitting pressure fluid into said second container for the purpose of pressuring said second container in order to force said liquid out of said second container, through said second tube and said nozzle, and out of said ports so as to remove clogged material from said ports and to irrigate said organ.
Claim 3
Dependent Claim
32 words
Apparatus as defined in claim 1 in which said nozzle is elongated and is formed with a plurality of angularly spaced webs, said ports being defined by the spaces between said webs.
Claim 4
Dependent Claim
45 words
Apparatus as defined in claim 1 further including tubular means located within said nozzle and communicating with said second tube, and at least one row of angularly spaced holes formed in said tubular means and defining passages permitting said liquid to flow into said nozzle.
Claim 5
Dependent Claim
21 words
Apparatus as defined in claim 3 in which axially spaced rows of angularly spaced holes are formed through said tubular means.
Claim 6
Dependent Claim
32 words
Apparatus as defined in claim 3 further including a second nozzle on one end of said tubular means and operable to cause said liquid to spray axially out of said tubular means.
Claim 7
Dependent Claim
38 words
Apparatus as defined in claim 5 in which said tubular means extends axially through said first nozzle, said second nozzle being located on the downstream end of said tubular means and being positioned outside of said first nozzle.
Claim 8
Dependent Claim
25 words
Apparatus as defined in claim 6 in which said second nozzle is selectively adjustable in order to change the spray emitted from said second nozzle.
Claim 9
Dependent Claim
26 words
Apparatus as defined in claim 1 in which said means on said second container comprise a valved fitting for admitting pressurized air into said second container.
Claim 10
Dependent Claim
26 words
Apparatus as defined in claim 1 in which said means on said second container comprise a valved fitting for admitting pressurized liquid into said second container.
Claim 11
Dependent Claim
32 words
Apparatus as defined in claim 1 in which said means on said second container comprise first and second valved fittings for respectively admitting pressurized air and pressurized liquid into said second container.
Claim 12
Dependent Claim
62 words
Apparatus as defined in claim 1 in which said suction pump comprises a cylinder, a pair of pistons spaced axially from one another within said cylinder and adapted to be reciprocated in unison in the cylinder, and a viscous semi-solid material packed between said pistons and operable to establish a seal between said pistons and said cylinder during reciprocation of said pistons.
Claim 13
Dependent Claim
221 words
Apparatus for aspirating and irrigating an organ of a non-human mammal, said apparatus comprising a nozzle shaped for insertion into the organ and having a plurality of ports, a first flexible tube having one end portion communicating with said nozzle, a first container for holding material aspirated from said organ, said tube having an opposite end portion communicating with said container, a hand-operated suction pump communicating with said container and selectively operable to create a negative pressure in said tube and said nozzle thereby to suck material from said organ into said ports and said nozzle, through said tube, and into said container, a second flexible tube located within said first tube and having one end portion communicating with said nozzle, a second container adapted to hold a liquid for irrigating said organ, means located within said first container for establishing communication between said second container and the opposite end of said second tube, and a valved fitting communicating with said second container for admitting compressed air into and retaining compressed air in said second container for the purpose of pressurizing said second container in order to force said liquid out of said second container, through said second tube and said nozzle, and out of said ports so as to remove clogged material from said ports and to irrigate said organ.
