Abstract

A drainage bag including a limp fluid receptacle portion and a stiffer header secured to the upper edge of the receptacle portion. The header is integrally formed with a drip chamber, and may also be formed with an air vent, a carrying and suspension hole, and stiffener ridges.

Claims

1. 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.

2. A body fluid drainage bag as defined in claim 1 wherein said header is also formed integrally with a through hole adapted to receive the fingers of a hand for carrying the bag and to receive hanger means for suspending the bag when in use.

3. A body fluid drainage bag as defined in claim 2 wherein said header includes integrally formed stiffner ridges thereon.

4. A body fluid drainage bag as defined in claim 1 wherein at least the drip chamber portion of said header is formed of transparent material.

5. A body fluid drainage bag as defined in claim 1 wherein said receptacle portion and header are formed of plastic and joined together by a heat seal.

6. A body fluid drainage bag as defined in claim 5 wherein the end of one of said receptacle sheets sandwiched between said header sheets extends beyond the edge of the other of said receptacle sheets and is heat sealed between said header valves, thereby giving the header added stiffness, with the edge of the other of said receptacle sheet heat sealed between said header sheets at the edge thereof adjacent said receptacle.

7. A body fluid drainage bag as defined in claim 1 wherein said header sheets include complementary channels extending along a tortuous path in said header, said channels cooperating to define an air vent passage therebetween communicating at one end with the interior of said receptacle and at its other end with the atmosphere through an aperture in one of said header sheets.
