A long member is covered with one-side coat member and an other-side coat member, which are colorless and transparent. The one-side coat member is fixed to the long member by a one-side fixing member. The other-side coat member is fixed to the long member by an other-side fixing member. The inner peripheral face of the one-side fixing member forms a tapered inner face part for introducing body fluid between the one-side coat member and the long member. The inner peripheral face of the other-side fixing member forms a tapered inner face part for introducing the body fluid between the other-side coat member and the long member. An insertion guiding member is mounted to the tip end part in an insertion direction of the long member. A middle part in the insertion direction of the insertion guiding member has a diameter larger than the base end part thereof. A vein ablating member is detachably mounted to the long member. A drug solution such as an anesthetic or the like is introduced into the other-side coat member for administration to a living body in or after surgery. Negative pressure is introduced into the other-side coat member to suck the body fluid in the vein and to suck air in organic tissue after stripping of the vein.
