The present invention discloses a positive-pressure double-nozzle nasal cavity cleaner featuring double pressure protection, and relates to the technical field of health care. The nasal cavity cleaner consists of a nose washing end, an upper shell, a core module, a control module, a lower shell, a liquid reservoir and a waste reservoir, wherein the nose washing end is rotatably connected to a top portion of the upper shell, and the nose washing end consists of a silicone washing nozzle, a silicone backflow nozzle and a rotary connecting base. The nasal cavity cleaner uses positive pressure and automatic pressure relief structures to obtain safe and constant air pressure, and then presses normal saline into the nasal cavity to clean the nasal cavity, so that pressure in the nasal cavity is small and stable during cleaning, which prevents damage to the nasal cavity and ear canal, thus being safer to use. Besides, deeper areas can be washed, nasal scabs in the nasal cavity can be moistened and removed, harmful substances such as dust in the nasal cavity can be removed, the nasal cavity can be moistened, and normal swing of nasal cilia can be recovered, which are helpful in treating rhinitis and preventing the onset of allergic rhinitis.

An assembly for nasal irrigation for the handheld irrigation of a user's nasal cavity comprising a housing with a refill chamber containing irrigating fluid, an applicator, an actuator for forcing irrigating fluid from the refill chamber through the applicator into the user's nasal cavity during operation, and a solution port for refilling the refill chamber. Some embodiments of the present invention may further comprise a system for nasal irrigation that includes the assembly for nasal irrigation or handheld irrigator, as well as a solution assembly structured for dispensing irrigating fluid to the handheld irrigator, a docking station for removably housing the handheld irrigator, a solution assembly and a refill control, including a check valve.

A collapsible nasal ejecting catheter, made of thermoplastic elastomer or other soft and elastic material, can be operated by the patients to insert into their nasal cavity and nasopharynx. The catheter includes a catheter body and a connector. The catheter has a flat closed distal end, a transitional segment starting from the closed end to a circular appearance, a normal segment having a circular appearance, and an open end on the opposite side of the flat closed end. There are multiple side-holes near the closed end. This catheter, when adapted to a connector and further connected to a syringe, can eject multiple strong thin spouts within the nasal cavity and nasopharynx for cleansing mucus and crust. The maximum width of the transitional segment is not less than 1 mm, and the minimum wall thickness of the catheter is not larger than 0.45 mm. Due to the flat closed distal end and transitional segment of the catheter body and its flexibility, the catheter with a larger outer diameter can be smoothly inserted into the slit-like space, reaching a deep depth to produce a better flushing efficiency, and also avoiding accidental entry into the sinus.

A therapeutic device for treating conditions of a user's nasal cavities, sinuses, and/or ear canals includes a housing which the user may hold to apply the therapeutic device to the user, the housing including an inlet that allows air to enter the therapeutic device. An acoustic vibrator located within the housing provides an acoustic vibration to the user, and a power supply located within the housing provides power to the acoustic vibrator. A mask is connected to the housing and includes a nasal interface that is appliable around the nose of the user. A valve of the mask opens to allow the user to breathe through the inlet and closes to prevent the user from exhaling through the inlet. The mask further includes a diaphragm and a nasal cavity in which a user's nostrils are located when the nasal interface is applied to the user.
