Treatment of blood containing vessels |
摘要 |
Method and apparatus are provided for treating one surface of a wall of articles to be used in contact with blood. A solution which is compatible with blood is brought into contact with the surface and a partial vacuum is applied to the wall for a predetermined time period. This partial vacuum causes gas nuclei trapped in irregularities in the surface to permeate through the wall. Consequently when blood displaces the solution there is less likelihood of blood platelets being trapped on the surface with eventual blood clotting.
