Abstract:
Apparatus for removing gas from blood comprising:a non-rotating centrifuge chamber having a shape which narrows in a tapering funnel manner from an upper portion above to a lower portion below, the chamber having a blood inlet to the wider top end and a blood outlet from the narrower lower end in order to reduce the loss of energy of rotation of a blood stream that is sucked through the chamber;the blood inlet to the chamber being oriented to be substantially tangential to the axis of rotation of the stream of blood in the centrifuge chamber to form a stream of blood rotating around the substantially vertical axis of rotation of the centrifuge chamber, the blood inlet into the chamber being further directed in the direction of the flow of blood obliquely downward into the centrifuge chamber with an upwardly open angle .beta. to the axis of rotation of less than 90.degree.;the blood outlet being connectable to a suction device for drawing blood through the centrifuge chamber from the inlet to the outlet without reversal of direction of rotation of the stream of blood in the chamber;a gas outlet located at a vertical elevation higher than the blood inlet to the centrifuge chamber and communicating with the blood inlet for drawing gas off from the surface of the stream of blood that is rotating in the centrifuge chamber, and the gas outlet being connectable to a suction device which enables the gas to be drawn off the surface of the stream of blood and through the gas outlet through a suction device;said apparatus being shaped so as to be gripped and carried with one hand.
