Evaluation of a disposable bubble oxygenator

Hazard of antifoam emboli from a bubble oxygenator.

One of the most popular types of heartlung machine has been the bubble oxygenator introduced by Clark, Gollan, and Gupta (1950) and this has been used successfully in the treatment of many hundreds of patients (Lillehei, Warden, DeWall, Stanley, and Varco, 1957; Cooley, Belmonte, De Bakey, and Latson, 1957). However, some workers have experienced difficulty in using this apparatus, particularly...

The transition from the bubble oxygenator to the microporous membrane oxygenator.

The transition from bubble oxygenators to microporous membrane oxygenators is a good example of how industry working with customers and material suppliers can help improve a surgical technique, such as cardiopulmonary bypass. The development is characterized by many individuals who, through their inventiveness and determination, made the transition possible. While the medical personnel involved...

A disposable rotating oxygenator capable of being sterilized by heat for a heart-lung machine.

This rotating oxygenator is of a design differing from other rotating oxygenators in that the large surface area necessary for filming blood at high rates of flow is obtained by using a small number of concentric drums rather than a large number of discs. This makes for simplicity of manufacture and ease of assembly. The design is such that it can be cast in plastic in three parts and mass prod...

Gas Exchange in the Rygg-kyvsgaard Bubble Oxygenator.

The Rygg-Kyvsgaard oxygenator employed in extracorporeal circulation (Fig. 1) was designed on the basis of experience gained from experimental operations on dogs (Rygg, Engell, and Kyvsgaard, 1956; Rygg and Kyvsgaard, 1957; Gammelgaard, Husfeldt, and Therkelsen, 1957; Rygg and Kyvsgaard, 1958; Rygg, 1958). However, in experimental operations the opportunities of assessing its oxygenation and ca...
