A device for rinsing the mouth after chemotherapy vomiting
By designing a nozzle replacement mechanism and a self-cleaning nozzle, the problems of non-adjustable water pressure, unstable nozzles, and high risk of cross-infection in existing devices have been solved. This has enabled a stable connection and personalized water pressure adjustment, reduced the risk of cross-infection, and improved the rinsing effect.

Abstract
This utility model relates to the technical field of medical equipment, and in particular to an oral irrigation device for post-chemotherapy vomiting, including a handle with a nozzle replacement mechanism on one side. This oral irrigation device for post-chemotherapy vomiting, through the nozzle replacement mechanism, allows for easy replacement of nozzle housings with different diameter holes to meet individual water pressure requirements. It also allows for one-time replacement to meet medical sterilization requirements, reducing the risk of cross-infection. Three sets of symmetrically arranged mounting components, limiting bases, locking springs, and locking rods securely engage the nozzle housing and mounting rod, preventing loosening or detachment during use. A shelf on one side of the movable base facilitates the storage and quick access of the mounting rod. The central axes of the holes on the mounting component and nozzle housing side coincide, ensuring smooth water flow, stabilizing water pressure and flow direction, and improving the effectiveness of oral irrigation.
