| 摘要 |
The present invention relates to a heat exchanger which is specifically adapted for use in connection with blood oxygenators, particularly bubble oxygenators. The core of the heat exchanger is generally cylindrical and closed at both ends. The cylinder is made of thin walled material with good heat exchange properties such as aluminum. The portion of the heat exchanger core which will be exposed to blood is coated with a biocompatible material such as tetrafluoroethylene. The heat exchanger may be connected to a source of heat exchange medium, such as water, through couplings in the top portion of the heat exchanger core. The heat exchange medium is then circulated through the core providing heating or cooling which is capable of heating or cooling blood within a bubble oxygenator. The heat exchanger core is then nested within a suitable receiver. The inner walls of said receiver may be reticulated in order to facilitate exchange of heat between the heat exchanger core and a fluid, such as blood, flowing between the outer wall of the heat exchanger core and the inner wall of the shell. |
