[Problems] body of the animal even have configured the entire length of the longer the catheter than the length in consideration of the optimal length of time of insertion into the urethra advance, its length is too long than the optimum length to provide a urinary catheter fixture can be fixed is surely brought into contact with. A urinary catheter fixing device includes a target sandwich member 1 made of an elastic member, and a clamping member 11. Clamped member 1 includes a cylindrical portion 3 which detachably clamping member 11 is fitted to the outer peripheral portion, the flange portion 5 in which a plurality of small holes provided at one end of the cylindrical portion is drilled, through It has a hole, and one of the slits. Slits are formed in the axial center direction over the entire area of the clamping member 1 in a direction along the axis of the insertion hole. The clamping member 11 by engaging the outer periphery of the cylindrical portion 3 of the clamped member, an outer diameter reduced in diameter in the outer peripheral portion of the cylindrical portion in a state in which the catheter 20 into the insertion hole of the clamped member is inserted direction of tightening force is applied.FIELD 5【課題】尿道に挿入する際の最適な長さを考慮した長さより長めにカテーテルの全長を予め設定しておき、その長さが最適な長さより長過ぎたとしても動物の体表に確実に当接させ固定することができる尿道カテーテル固定具を提供する。【解決手段】尿道カテーテル固定具は、弾性部材からなる被挟持部材1と、挟持部材11とを備える。被挟持部材1は、外周部に着脱可能に挟持部材11が嵌合される筒状部3と、筒状部の一端部に設けられ複数の小孔が穿設された鍔部5と、挿通孔と、1つのスリットとを有する。スリットは、挿通孔の軸芯に沿う方向の被挟持部材1の全域に亘って軸芯方向に形成されている。挟持部材11を被挟持部材の筒状部3の外周部に嵌合することで、被挟持部材の挿通孔にカテーテル20が挿通された状態の筒状部の外周部にその外径が縮径する方向の緊締力が付与される。【選択図】図5
