Detailed Description

In order to deepen the understanding of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and embodiments, which are only used for explaining the present invention and are not limited to the protection scope of the present invention.

Examples

As shown in fig. 1 to 3, the present embodiment provides an anti-reflux anal tube, which comprises a tube head 1, an administration tube 2, an extension tube connector 3, and an extension tube 4; the tube head 1 comprises an inner flow passage 11; the rear side of the inner runner 11 is provided with an anti-reverse cavity 12, and the middle of the inner runner is provided with a ball blocking frame 14; the front end of the administration tube 2 is inserted at the rear end of the anti-reverse cavity 12 of the tube head 1; an anti-reverse ball 13 is also arranged in the anti-reverse cavity 12; the rear end of the administration tube is connected with an extension tube 4 through an extension tube joint 3; the extension pipe joint 3 comprises an administration pipe connecting cavity 31 of the front half part and an extension pipe connecting cavity 32 of the rear half part; clamping convex ridges 36 are annularly arranged on the inner wall of the administration tube connecting cavity 31 and the inner wall of the extension tube connecting cavity 32; a thickened part 35 is arranged at the opening part of the front end of the extension pipe joint 3; four axial reinforcing ribs 33 are uniformly distributed on the outer wall of the extension pipe joint 3 positioned in the administration pipe connecting cavity 31 in the circumferential direction; the extension pipe joint 3 is provided with a reinforcing ring 34 on the outer wall of the extension pipe connecting cavity 32; the front end of the tube head 3 is provided with a bulb 15; the pipe head 3 is also provided with a small hole 16 near the front end; the diameter of the anti-reverse ball 13 is smaller than the inner diameter of the anti-reverse cavity 12 and larger than the inner diameter of the administration tube 2; the ball blocking frame 14 is in a hollow cross shape, four edges of the hollow cross shape are integrated with the tube head 1, and the inner diameter of the ball blocking frame 14 is smaller than the diameter of the anti-reverse ball 13.
