A fluid flow detector includes a detector main body defining a fluid flow channel having a fluid flow detection channel positioned adjacent an upstream hole and a discharge channel positioned adjacent a downstream hole. A mobile body is positioned within the fluid flow channel and dimensioned to be movable along the fluid flow channel. The diameter of the fluid flow detection channel is smaller than the diameter of the discharge channel, and the maximum diameter of the outer peripheral edge part of the face of the fluid flow channel orthogonal to the direction of movement of the mobile body is slightly smaller than the diameter of the fluid flow detection channel. The upstream hole and the downstream hole are formed with a size and shape such that fluid can flow through the upstream and downstream holes without being obstructed by the mobile body.

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 catheterincluding a flexible, hollow PEG tubereinforced with filaments, an deformable intragastric retainerpositioned at the trailing end of the PEG tube, and a tapered memberpositioned at the leading end of the PEG tubefor retaining the leading end portionof a guide wireinserted from a leading end holethereof; and an infection-preventing sheathincluding a flexible, hollow tubular body, and a socket member having a socketpositioned at the trailing end of the tubular bodyfor retaining the intragastric retainer, and pins, thereby removably sheathing the gastrostomy catheter. The gastrostomy cathetermay be provided with a housing sheathfor deforming and housing the intragastric retainer
