Abstract:
A system for introducing gas-supersaturated fluid into blood of a patient, comprising:an extracorporeal blood circulation circuit adapted to receive, circulate and return blood to the patient;at least one channel opening into said circuit for delivering gas-supersaturated fluid to said circuit; anda device for introducing gas-supersaturated fluid into blood in said circuit while minimizing bubble formation, the device controlling fluid flow to minimize turbulence at the point of introduction of gas-supersaturated fluid into the blood flow, the device comprising a mixing region defined by a flow passage with an inner wall, an upstream entry, and a downstream exit, wherein said flow passage inner wall tapers from a larger inner diameter at the upstream entry to a smaller inner diameter at the downstream exit and said at least one channel opening is disposed in an area having said larger inner diameter.
