Abstract

A method of firmly securing a catheter body to a surface portion of human skin, without causing the catheter body to be bent or reducing the diameter of the inner passage of the catheter body. This method employs a catheter-securing member which comprises a cylindrical body for allowing the catheter body to be slidably inserted therein, and a slit is provided along the axial direction of the cylindrical body. In this method a ligature is first pierced through a surface portion of human skin and tied over the surface of human skin, leaving a pair of free end portions extending out of the skin, and then the cylindrical body is secured with the free end portions of the ligature by winding the ligature around the cylindrical body and fastening them.

preparing a cylindrical body to have (a) a hollow portion into which said catheter body is slidably inserted in an axial direction of said cylindrical body, and (b) a slit formed to extend from one end to the other end and along the axial direction of said cylindrical body, and said slit reaching said hollow portion;
piercing a middle portion of a ligature through a surface portion of human skin, tying the middle portion of the ligature over the surface portion of human skin, and extending a pair of free end portions of said ligature out of the skin for fastening said cylindrical body;
and
securing said cylindrical body with said pair of free end portions of the ligature by winding said ligature around said cylindrical body and fastening said ligature to tighten the catheter body, thereby securing the cylindrical body as well as the catheter body to a surface portion of human skin.
