Preferably, the large-diameter section includes a diameter constant portion near the small-diameter section and a diameter gradual change portion far from the small-diameter section, and the diameter of the diameter gradual change portion gradually decreases from near the small-diameter section to far from the small-diameter section.
Preferably, the wall of the diameter-tapered portion gradually decreases in thickness from near the small-diameter section to far from the small-diameter section.
Preferably, the length of the constant diameter portion is greater than the length of the gradual diameter portion.
Preferably, the end of the small diameter section extends into the large diameter section and forms an end platform in the large diameter section.
Preferably, an inner limiting platform is arranged on the inner wall of the large-diameter section, the end part of the inner limiting platform is flush with the end part of the end part platform, and the height of the inner limiting platform is 0.5-1cm.
Preferably, a groove is formed between the part of the small-diameter section extending into the large-diameter section and the inner wall of the large-diameter section.
Preferably, a raised ring with an increased inner diameter is provided between the proximal end and the end of the large diameter section. The diameter of the raised ring is equal to or slightly greater than the diameter of the distal portion. Slightly larger then means 1.1-1.3 times the diameter of the distal portion.
Preferably, the inner surface of the large-diameter section is provided with anti-skid patterns, and the outer surface of the distal end of the small-diameter section is provided with anti-skid patterns.
Through implementing the technical scheme, the invention realizes the conversion between two pipe bodies with different diameters, has no obvious protrusion in appearance when large and small-specification pipes are converted, can not be increased in the cross section diameter of a certain section, has high comfort level for users, and has smooth connection of internal cavity channels, so that a guide wire can smoothly pass through, and the phenomenon that the guide wire is clamped in the pipes can not occur.

FIG. 2 is a cross-sectional view of FIG. 1;
FIG. 3 is a cross-sectional view of FIG. 1;
Fig. 4 is a partially enlarged schematic illustration of fig. 2.
Detailed Description
The invention will now be described in further detail with reference to the drawings and to specific examples.
The utility model provides a nose intestines tube conversion connecting piece, is shown as fig. 1,2,3, 4, includes main part 1, adopts hardness 60~80A material preparation for bonding coincidence portion is soft, and flexible can not hard top human body when passing through the human body cavity, and is more comfortable, main part 1 includes big footpath section 11 and diameter is less than big footpath section 11's minor diameter section 12, minor diameter section 12 is including connecting big footpath section 11's proximal end portion 121 and keep away from big footpath section 11's distal end portion 122, proximal end portion 121's diameter is less than distal end portion 122's diameter. The large diameter section 11 includes a diameter constant portion 111 near the small diameter section 12 and a diameter gradual change portion 112 distant from the small diameter section 12, the diameter of the diameter gradual change portion 112 gradually decreases from near the small diameter section 12 to distant from the small diameter section 12, and the thickness of the wall of the diameter gradual change portion 112 gradually decreases from near the small diameter section 12 to distant from the small diameter section 12.
The length of the constant diameter portion 111 is greater than the length of the diameter-gradual-change portion 112.
The end of the small diameter section 12 extends into the large diameter section 11 and forms an end platform 123 within the large diameter section 11. The inner wall of the large-diameter section 11 is provided with an inner limit platform 113, which can be formed by protruding and inner wall, or can be formed by forming a concave ring on the inner wall and forming a gap between the concave ring and the end platform 123. The end of the inner limit platform 113 is flush with the end of the end platform 123.
A groove 124 is formed between the portion of the small diameter section 12 extending into the large diameter section 11 and the inner wall of the large diameter section 11. A raised collar 125 of increased inner diameter is provided between the proximal end 121 and the end of the large diameter section 11. The diameter of the raised ring 125 is equal to the diameter of the distal portion 122 or 1.1-1.3 times the diameter of the distal portion 122, and this embodiment is set equal to the diameter of the distal portion 122. The inner surface of the large diameter section 11 is provided with anti-skid patterns, and the outer surface of the distal end of the small diameter section 12 is provided with anti-skid patterns.
