The end sleeve 16b is connected with the round pipe section 16b2 in the backward direction of the conical section 16b1, and the effect of preventing the nasogastric scope 4 from protruding out from the front end opening 11 is achieved by utilizing the opening caliber of the conical section 16b1 to be smaller than the pipe diameter of the nasogastric scope 4. The sleeve 16c engages the circular tube section 16c2 rearwardly of the tapered section 16c1 and forms a top surface 16c3 at the leading end and a cross cut 16c4 in the top surface 16c 3.

Referring to fig. 1 to 3, it is described that the pipe diameters of the first pipe 1 from the front end opening 11 to the rear end opening 12 are similar.

Fig. 14 shows that the diameter of the rear section of the first pipe 1 is larger than that of the front section of the first pipe 1.

Fig. 15 to 17 show that the pipe diameter of the front section of the first pipe body 1 gradually decreases and then gradually increases from the front end opening 11 in the axial direction, and the pipe body of this section is formed into an arc-shaped concave shape.

Please refer to fig. 18. In a preferred embodiment of the present invention, a flexible section 17 is further formed at the front end of the first tube 1.

FIG. 19 shows the flexible section 17 as a bellows tube having a saw-toothed cross section; in fig. 20, the flexible segment 17 is disclosed as a bellows tube having an arc-shaped cross section.
