An infection-preventing gastrostomy catheter kit to be used in the gastrostomy, which can pass an intragastric retainer of a catheter easily and reliably through an infection-preventing sheath by an easy maneuver, and which can reduce the diameter of the infection-preventing sheath. The catheter kit comprises: a gastrostomy catheter (20) including a flexible, hollow PEG tube (21) reinforced with filaments (24), an deformable intragastric retainer (23) positioned at the trailing end of the PEG tube (21), and a tapered member (22) positioned at the leading end of the PEG tube (21) for retaining the leading end portion (40a) of a guide wire (40) inserted from a leading end hole (22a) thereof; and an infection-preventing sheath (1) including a flexible, hollow tubular body (2), and a socket member having a socket (4) positioned at the trailing end of the tubular body (2) for retaining the intragastric retainer (23), and pins (5), thereby removably sheathing the gastrostomy catheter (20). The gastrostomy catheter (20) may be provided with a housing sheath (60) for deforming and housing the intragastric retainer (23). |
