Blood chambers of counterpulsation heart pumps were subjected to a special hydrophilization process in order to reduce the coagulation activity of the surface of poly(methyl methacrylate) (PMMA). The chemical treatment of the surface was carried out in three variants, namely A (ethylenglycol), B (diethylenglycol), C (glycerine) by using concentrated sulphuric acid with subsequent neutralization [12]. Controls were performed with the same pumps made of PMMA but without surface treatment. 30 dogs were used in the experiments.
为降低聚甲基丙烯酸甲酯（PMMA）表面的凝血活性，对反搏心脏泵的血腔进行了特殊的亲水化处理。表面化学处理采用三种变体，即A（乙二醇）、B（二甘醇）、C（甘油），使用浓硫酸处理后再进行中和[12]。对照组使用相同的由PMMA制成但未进行表面处理的泵。实验中使用了30只狗。
