Abstract
A system for collecting fluids from medical procedures, laboratory testing or industrial processes using a vacuum pad placed on the floor or an appropriate supporting structure adjacent to a potential source of hazardous fluids. The vacuum pad is formed from corrugated panels having a first sheet and a second sheet with a plurality of corrugated ribs to provide fluid flow channels between the first sheet and the second sheet. A manifold is provided as a part of the vacuum pad to supply a relatively uniform amount of vacuum to each fluid flow channel. The vacuum pad and a container for potentially hazardous fluids may be coupled in series by one or more conduits to a vacuum source such as commonly available in surgical operating rooms.
