Abstract
An atraumatic method and apparatus for the removal of fluid from a surgical field having a fluid valve which is opened and closed responsive to the pressure about the fluid valve and a vacuum valve which is also opened and closed in response to the pressure about the fluid valve, and when opened, causes fluid to be passed through the fluid valve. In one embodiment, the fluid valve is made of collapsible tubing, flattened at its midsection so as to be normally closed, and connecting a fluid inlet and fluid outlet of a fluid removal housing. The fluid removal housing is further provided with a control port which may be opened or closed manually, and a connection to a vacuum source through the vacuum valve.
