Claim 1
Independent Claim 125 words
A body fluid drainage bag, comprising a receptacle, formed of two sheets of limp material sealed along their edges, within which body fluid is accumulated, and a header formed of two sheets of stiffer material sealed together and secured to one side of said receptacle with the adjacent edge of said receptacle sandwiched between the two header sheets, said header sheets being two matching halves of said header with each half being the mirror image of the other and having at least one depression formed therein, said depressions being complementary to each other and defining an integral drip chamber in said header for communicating at one end with the interior of said receptacle and attachable at its other end to a length of drainage tubing.
Claim 2
Dependent Claim 125 words
A body fluid drainage bag, comprising a receptacle, formed of two sheets of limp material sealed along their edges, within which body fluid is accumulated, and a header formed of two sheets of stiffer material sealed together and secured to one side of said receptacle with the adjacent edge of said receptacle sandwiched between the two header sheets, said header sheets being two matching halves of said header with each half being the mirror image of the other and having at least one depression formed therein, said depressions being complementary to each other and defining an integral drip chamber in said header for communicating at one end with the interior of said receptacle and attachable at its other end to a length of drainage tubing.
