Nasal irrigation device with adjustable flow rate and controllable direction

Abstract

A nasal irrigation device with adjustable flow rate and controllable direction mainly comprises a container for holding liquid, a tube connected to the container, and a nozzle at the end of the tube for controlling the direction. The container has two convection channels, the tube has an inclined section with an appropriate angle and a continuously bent extension section, and the nozzle has an outlet on the side. This makes the nasal irrigation device more ergonomic during use, increasing compliance, improving comfort, and reducing the side effects and discomfort of water accumulation in the ear. During use, the two convection channels regulate air convection within the container, thereby adjusting the flow rate of the liquid according to the usage situation, making the liquid flow smoother. The nozzle can control the direction of the water flow, concentrating the water flow towards the inferior turbinate or the sinus opening for precise nasal irrigation.
