Abstract
A medical instrument having a blood contact portion formed of a hydrophobic material, wherein a surface-active agent safe to a human body is deposited onto part or the entirety of the blood contact portion so that the medical instrument is fully primed by introducing liquid into the instrument without leaving fine bubbles adhered to the surface of the blood contact portion. Further, a method for fabricating a medical instrument is provided, comprising steps of assembling a medical instrument having a blood contact portion formed of a hydrophobic material, and contacting a liquid containing a surface-active agent safe to a human body to the blood contact portion, followed by drying, leaving the surface-active agent deposited onto the surface of the blood contact portion so that the surface-active agent is steadily and readily deposited onto the blood contact portion of hydrophobic material.
