Abstract
Abstract A suction drainage device is disclosed which comprises a receptacle communicated with a body cavity via an inlet tube. The receptacle is formed as a bellows, flat receptacle, foil or sheet bag, or foil or sheet tube and the like which can be folded or rolled up. A flexible check valve in the form of a foil or sheet valve, or flutter valve, is disposed inside the receptacle. The inlet tube is provided on a side of one edge of the receptacle so that the receptacle can be rolled up over a long roll path without interference from the valve. The device can be manufactured at low cost.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
133 words
A suction drainage device comprising a receptacle of flexible material capable of being folded, rolled and the like, fluid-sorbing material disposed in the receptacle, fluid passage means coupling the exterior of the receptacle to the interior of the receptacle and adapted to be communicated with a source of fluid located at the exterior of the receptacle, and a flexible check valve disposed in the receptacle at a side of one edge of the same and being operative to seal and open communication between the interior of the receptacle and said passage means in response to the condition of the receptacle and a thin tube extending through the flexible valve to the exterior of the receptacle through said passage means which is adapted to be pulled out of the valve and said passage means.
Claim 2
Dependent Claim
133 words
A suction drainage device comprising a receptacle of flexible material capable of being folded, rolled and the like, fluid-sorbing material disposed in the receptacle, fluid passage means coupling the exterior of the receptacle to the interior of the receptacle and adapted to be communicated with a source of fluid located at the exterior of the receptacle, and a flexible check valve disposed in the receptacle at a side of one edge of the same and being operative to seal and open communication between the interior of the receptacle and said passage means in response to the condition of the receptacle and a thin tube extending through the flexible valve to the exterior of the receptacle through said passage means which is adapted to be pulled out of the valve and said passage means.
