Abstract
An apparatus for collecting and salvaging blood includes: a first chamber with a below atmosphere internal pressure for continuous collection of blood through an inlet port; a second chamber for receiving blood from the first chamber through a connection channel; a channel valve manually controllable to close the connection channel; and a control for simultaneously controlling the channel valve and the internal pressure of the second chamber between an internal pressure corresponding to the internal pressure of the first chamber and ambient air pressure, wherein the control is arranged to provide an internal pressure corresponding to the internal pressure of the first chamber to the second chamber through a passageway separated from the connection channel for providing blood from the first chamber to the second chamber.
