摘要:
An object of the present invention is to provide an antibacterial medical equipment which has sufficient antibacterial activity in vivo and is excellent in compatibility with living tissues, and also can maintain antibacterial activity over a long period and has high safety.An antibacterial medical equipment characterized in that inositol phosphate is bonded to a Ca compound of a medical equipment whose surface is at least coated with a layer of the Ca compound, or a medical equipment comprising the Ca compound. The antibacterial medical equipment as described above, wherein silver ions are bonded to the inositol phosphate. A method for producing an antibacterial medical equipment, which comprises bringing a medical equipment whose surface is at least coated with a layer of a Ca compound, or a medical equipment comprising a Ca compound into contact with an aqueous solution of inositol phosphate to obtain an antibacterial medical equipment in which inositol phosphate is bonded to the Ca compound. The method for producing an antibacterial medical equipment, wherein inositol phosphate is bonded to the Ca compound and then the Ca compound is brought into contact with an aqueous solution containing silver ions to obtain an antibacterial medical equipment in which silver ions are bonded to the inositol phosphate.
