Abstract
Abstract A receptacle 10 for collecting fluid, especially suitable for use on the floor of an operating room for collecting irrigating fluid during a surgical procedure, for example, during arthroscopic surgery on a joint, such as the knee. The receptacle is thin and generally flat, with a gridwork of small basins 12 that form a collecting surface 14 with drains 24 through which the fluid flows to channels 16 formed between the receptacle and floor and thence to a common discharge port 20, which suitably may be connected to a suction device, such as an aspirator.
