Total Claims: 21
Claim 1
Independent Claim
172 words
A liquid collection unit comprising: a bag having flexible side walls sealed on the side edges; a substantially rigid lower support member positioned between the bottom edges of said side walls and sealed to the interior surface of the side walls adjacent the bottom of said bag, with said bag side edges and lower support member defining a liquid collection chamber in the bag, and said lower support member providing support for the side walls; a substantially rigid upper support member positioned between the top edges of said side walls and sealed to the interior surface of the side walls such that said upper support member has a surface exterior of the collection chamber and a surface interior of the collection chamber, said upper support member providing a support for the side walls from which the flexible side walls are suspended and held extended therealong; and a drip site chamber extending through the interior of the upper support member and providing a passway from the exterior to the interior of the bag.
Claim 2
Dependent Claim
172 words
A liquid collection unit comprising: a bag having flexible side walls sealed on the side edges; a substantially rigid lower support member positioned between the bottom edges of said side walls and sealed to the interior surface of the side walls adjacent the bottom of said bag, with said bag side edges and lower support member defining a liquid collection chamber in the bag, and said lower support member providing support for the side walls; a substantially rigid upper support member positioned between the top edges of said side walls and sealed to the interior surface of the side walls such that said upper support member has a surface exterior of the collection chamber and a surface interior of the collection chamber, said upper support member providing a support for the side walls from which the flexible side walls are suspended and held extended therealong; and a drip site chamber extending through the interior of the upper support member and providing a passway from the exterior to the interior of the bag.
Claim 3
Dependent Claim
64 words
A liquid collection unit in accordance with claim 1 wherein said drip site chamber includes, an inlet port at the surface of said upper support member exterior of the liquid collection chamber adapted to receive a fluid conducting tube, and an exit port at the surface of said upper support member located interiorly of said collection chamber and axially aligned with said inlet port.
Claim 4
Dependent Claim
44 words
