A wetting assembly for wetting an insertion tube and a medical device

Abstract

The application discloses a wetting assembly for wetting an insertion tube and a medical device, and belongs to the technical field of medical devices. The insertion tube is used for being inserted into a cavity, and the wetting assembly has a containing cavity. The containing cavity is used for storing liquid, and the containing cavity has an opening. The liquid stored in the containing cavity can flow out through the opening. The wetting assembly is used for being movably matched with the insertion tube. In the case that the wetting assembly is assembled to the insertion tube, the insertion tube is located on the flow path of the liquid flowing out of the opening. The wetting assembly is movably matched with the insertion tube. The containing cavity in the wetting assembly is used for storing liquid. In the case that the wetting assembly is assembled to the insertion tube, the liquid in the containing cavity can flow out of the opening of the containing cavity, and the insertion tube is located outside the flow path of the liquid. Therefore, the liquid can be coated on the surface of the insertion tube, so that the outer wall of the insertion tube can be kept in a wet state. The friction between the outer wall of the insertion tube and the inner wall of the cavity is reduced, and the insertion resistance of the insertion tube is reduced.
