Claim 9

The isolation cage ward set forth in claim 5 including: (a) a cover mounted over each of said exhaust port means; (b) said cover having a detachable and replaceable filter element therewith.

Claim 10

The isolation cage ward set forth in claim 5 wherein: (a) said plenum extends between said upper and lower units and along a side wall of said upper confinement unit; and (b) said exhaust blower is mounted in said plenum beside of a side wall of said upper confinement unit.

Claim 11

An animal isolation cage ward comprising: (a) a generally rectangular housing having a back wall, opposite side walls, top and bottom walls and an open front; said housing being mounted on wheels for mobility; (b) upper and lower confinement units mounted in said housing with each of said units including top, bottom, back and opposite side walls and an open front, said units being spaced from said housing back, opposite side and top and bottom walls and with said open front of each of said units coinciding with said housing open front; (c) said lower confinement unit being larger than said upper confinement unit; (d) resistance heating pads mounted to said opposite side walls of said units and with a temperature control panel situated on said housing adjacent said upper unit; (e) doors of impervious synthetic transparent plastic material respectively mounted over the open fronts of said units from a said side wall thereof, said doors being slightly smaller than said units open fronts and having a gap around the periphery of each of said doors for airflow into said units; (f) said doors respectively having a bottom hinged section swingably mounted to said doors for access to an interior of said units without opening said doors; (g) exhaust port means extending through the respective top walls of each of said units; (h) a plenum within said housing extending along the top walls of said units and along said side wall of said upper unit; (i) an exhaust blower mounted in said housing for drawing air through said plenum; said exhaust port means, said units and around said doors from atmosphere exterior of said housing; (j) a duct connection to said exhaust blower for routing contaminated air outwardly; and (k) a filter at said duct connection for trapping particulate matter.

Claim 12

An animal isolation cage ward comprising: (a) a generally rectangular housing having a back wall, opposite side walls, top and bottom walls and an open front; said housing being mounted on wheels for mobility; (b) upper and lower confinement units mounted in said housing with each of said units including top, bottom, back and opposite side walls and an open front, said units being spaced from said housing back, opposite side and top and bottom walls and with said open front of each of said units coinciding with said housing open front; (c) said lower confinement unit being larger than said upper confinement unit; (d) resistance heating pads mounted to said opposite side walls of said units and with a temperature control panel situated on said housing adjacent said upper unit; (e) doors of impervious synthetic transparent plastic material respectively mounted over the open fronts of said units from a said side wall thereof, said doors being slightly smaller than said units open fronts and having a gap around the periphery of each of said doors for airflow into said units; (f) said doors respectively having a bottom hinged section swingably mounted to said doors for access to an interior of said units without opening said doors; (g) exhaust port means extending through the respective top walls of each of said units; (h) a plenum within said housing extending along the top walls of said units and along said side wall of said upper unit; (i) an exhaust blower mounted in said housing for drawing air through said plenum; said exhaust port means, said units and around said doors from atmosphere exterior of said housing; (j) a duct connection to said exhaust blower for routing contaminated air outwardly; and (k) a filter at said duct connection for trapping particulate matter.
