Abstract
Abstract Devices for collecting fluids from a patient are disclosed. The present invention includes a first sheet of liquid impervious material having an opening. The first sheet is attached to a bottom sheet of liquid impervious material having a fenestration for access to the patient. A bendable section disposed along the inner perimetric edge of the first sheet retain the edge in a particular defined shape, improving fluid collection and access. The bendable section preferably includes a wire covered by a pliable plastic material, which are encased by providing a second sheet of liquid impervious material and placing the bendable section between the first second sheets. The sheets are then preferably secured by heat sealing. In certain preferred embodiments adhesive is provided on the patient facing side of the fenestration section and drainage ports for transmitting fluids are affixed to the bottom sheet. The present invention also provides a surgical drape including a sheet of drape material having an opening for access to the patient and having a device for collecting fluids as described above attached to it. Such drapes may also include a pad of absorbent material overlying the drape material and a device for retaining a drainage tube. Methods of manufacturing a fluid collecting device are also disclosed.
