ABSTRACT:
An anti-infective catheter on which a layer of a water absorbing polymer is formed. Since the layer of the water absorbing polymer swells by absorbing body fluid in subcutaneous tissue, space between the inserted catheter and its peripheral skin moiety is filled quickly, thus preventing penetration of pathogens in the living body along the wall of the catheter. The anti-infective catheter of the present invention can be inserted in the living body easily without forming a site for the arrangement of a cuff and can prevent penetration of pathogens immediately after its insertion without affecting peripheral tissue.
