The sum of the lengths of the transition straight pipe and the near end of the interventional catheter is the same as the length of the pipe body part of the straight pipe, so that the head end of the interventional catheter is just in the cavity of the end part of the protective pipe head, and the shape of the head end is protected from deformation.
In order to further solve the problem that can't protect the shape of the catheter head end, the utility model provides a scheme as follows: the protection tube head end part and the interventional catheter head end are both provided with radians, and the bending shapes and the bending angles are completely the same. The consistent bending shape and angle are kept, so that the shape of the head end of the interventional catheter can not be collided with the end part of the protective tube head all the time to cause deformation on the premise of firm connection.
In order to further solve the problem that can't protect the shape of the catheter head end, the utility model provides a scheme as follows: the bottom end of the bending part extending from the head end of the interventional catheter is always positioned above the bottom end of the inner wall of the straight pipe body part. The bottom of the extension bending part of the interventional catheter head end is limited, so that the interventional catheter head end is ensured not to generate collision deformation in the process of penetrating the straight pipe body part.
The protection tube is made of medical high polymer materials, and specifically comprises materials such as High Density Polyethylene (HDPE), polypropylene (PP), Polytetrafluoroethylene (PTFE) and the like. The medical polymer material is healthy, nontoxic and very environment-friendly.
The utility model has the advantages that: the utility model discloses a packing protection tube can protect the pipe can not damage at the in-process of storing and transporting to keep the head end shape can not warp.
