Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 to 5, the utility model provides a pipeline structure for a noninvasive ventilator, which comprises a nasal obstruction tube 1, wherein rubber tubes 2 are movably sleeved in the interiors of the left end and the right end of the nasal obstruction tube 1, sliding grooves 3 are formed in circumferential arrays on the surfaces of the left side and the right side of the rubber tubes 2, sliding blocks 4 are movably arranged in the sliding grooves 3, and conical tables 5 are fixedly arranged in the interiors of the left end and the right end of the sliding blocks 4.

The scheme is adopted: when the nose plug is used, the rubber tube 2 is inserted into the surface of the conical table 5 in the nose plug tube 1, and then the sliding block 4 is moved along the sliding groove 3, so that the bottom of the sliding block 4 is extruded by the surface of the rubber tube 2;

by the cooperation of the truncated cone 5 and the sliding block 4, the inner and outer surfaces of the rubber tube 2 are simultaneously extruded, so that the fixing effect is better.
