A membrane type blood oxygenating system with the membrane device, blood heater and blood reservoir constructed as an integral unit with the membrane device located lower than the blood reservoir.

Integral blood oxygenator

A fitting for connecting a helically corrugated heat exchanging tube to a source of heated fluid, the fitting having a plastic tubular member with an end adapted for connection to the source and an end with external helical threads formed on it, the threads being sized to provide a close clearance with the interior surface of the corrugated tube.

Fitting for corrugated tube

Blood oxygenating apparatus having a sampling access device connected to the blood outlet port and a blood inlet port of the apparatus by a sample supply line and return line and means to cause the pressure at the blood outlet port to be sufficient to cause a small continuous flow of blood through the lines and access device.

Sampling device for blood oxygenator

Potting the spaced-apart fold edges of a pleated membrane and spacer stack to the interior of a housing without blocking the fluid passages between the spaced-apart pleats by applying a layer of thixotropic adhesive to the fold edges of the pleated membrane and spacer stack and thereafter injecting the potting material between the layer of thixotropic adhesive and the housing.

Pleated membrane transfer device utilizing potting and thixotropic

A membrane type blood oxygenator with a microporous membrane separating blood and air channels, the blood in the blood channels flowing downward to cause any accidentally introduced air bubbles to have an increased residence time in the membrane device owing to buoyancy, the blood being at a pressure sufficiently greater than the air pressure to cause passage of air bubbles through the pores of the microporous membrane to the air side prior to being carried out of the device by flowing blood.
