Abstract
A blood suction device for removing blood from a surgical field is provided which can be controlled by a pressure sensing means mounted on a suction tip of the device for starting and stopping the roller pump of the device, and changing the revolution rate of the roller pump, thus enabling to reduce possible hemolysis, clothing and other undesirable effects. The blood suction device comprises pressure sensing means for detecting the pressure exerted thereupon which can be handled adjacent the suction tip by means of pneumatic pressure, and control means for controlling the revolution rate in response to the sensed pressure. The revolution rate when the device is not gripped or pushed by the operator may be set either at zero revolution or at any desired revolution.
