First Claim
Patent Images
1. A display device for an animal circulatory system comprising:
- a sheet material base, an animal likeness depicted on the front side of said base, a plurality of apertures formed within said base in the area of said likeness;
a first flexible transparent fluid conduit system fixedly positioned upon said base, said first fluid conduit system passing through said apertures in such a manner to similarly represent upon said front the arteries of the animal;
first pump means for moving a first colored fluid comprising a mixture of gas and liquid through said first fluid conduit system;
a second flexible transparent fluid conduit system fixedly positioned upon said base, said second fluid conduit system passing through said apertures in such a manner to similarly represent upon said front the veins of the animal;
second pump means for moving a second colored fluid comprising a mixture of gas and liquid through said second fluid conduit system;
visual differentiation means distinguishing said first system from said second system; and
each of said first and second pump means comprises separate centrifugal pumps, said gas formed by cavitation within said pumps.
