Plastic resinous tubes, particularly for medical use is improved in blood compatibility when brought into contact with blood, by applying a low-temperature plasma treatment to inner surfaces of the tubes, which plasma is produced through electrodeless electric discharges by the effect of microwave to make it possible to prevent the tube from being heated in such a treatment. The inner surfaces of the tubes thus activated may be further subjected to an inner surface graft copolymerization treatment to enhance blood compatibility.

Process for manufacture of plastic resinous tubes

An adhesion preventive for preventing adhesion between vital tissues is provided. The present adhesion preventive is a molded material consisting essentially of a biodegradable and absorbable polymer. It has an advantage of requiring no reoperation for its removal since it would be degraded and absorbed after completing its function in vivo.
