In order that the above-recited objects, features and advantages of the present utility model will become more readily apparent, a more particular description of the utility model will be rendered by reference to the appended drawings and appended detailed description.

Referring to fig. 1-2, the present embodiment provides a ventilation assist device for use after a posterior pharyngeal wall-valve pharyngeal forming operation, comprising:

the support system comprises two support rings 1, the two support rings 1 are matched with the nostril shape of the human body, and a connecting strip 2 is fixedly connected between the two support rings 1;

the side pipeline system comprises two pipelines 3, the two pipelines 3 are fixedly connected with the two support rings 1 respectively, two ends of each pipeline 3 are communicated with the outside, and a trash discharging assembly is arranged on the side wall of one end, away from the support ring 1, of each pipeline 3.

Support two pipelines 3 through supporting ring 1 and connecting strip 2 to in inserting the nasal cavity with two pipelines 3, by two pipelines 3 support the air vent that establishes in the art respectively, can reach the help postoperative and maintain nasal cavity ventilation, maintain air vent aperture size, avoid the postoperative to appear nasal cavity choking's emergence, avoid the postoperative because scar contracture, lead to nasal cavity ventilation not enough, and through the one end lateral wall of keeping away from supporting ring 1 at pipeline 3 offer the trash removal subassembly, can open supplementary postoperative clearance pharyngeal cavity secretion, avoid appearing the too much blocking pharyngeal cavity of secretion, appear the effect of choking risk.
