PURPOSE:To obtain a medical utensil excellent in the preservability of erythrocytes and having high physiological safety, autoclave sterilizable heat resistance, high transparency and flexibility, by compounding specific monocarboxylic ester with a soft resin composition containing no plasticizer. CONSTITUTION:The medical utensil is constituted of a soft resin composition prepared by compounding a soft resin composition containing no plasticizer with monocarboxylic ester represented by RCOOR' (wherein R and R' are respectively a 3C or more linear hydrocarbon group and the sum of the number of carbon atoms of R and R' is 11-30 and at least one of R and R' has a branch structure). When this soft resin composition is brought into contact with blood, the hemolysis of erythrocytes is prevented by the action of the monocarboxylic ester compound eluted and transferred from the resin composition and, since a substance suppressing platelet coagulating capacity is not eluted, this composition is excellent in the safety to a living body and has excellent protective action to erythrocytes. |
