A catheter, including a catheter body and a connector, can be adapted to a syringe for nasal flushing treatment. The catheter body is made of a soft material and has a flat closed distal end, a transitional segment having a flat closed segment and a lumen-containing oval segment, a circular normal segment and an open end on the opposite side of the flat closed distal end as well as multiple side-holes disposed near the closed end so that the catheter can be operated by patient to insert into a slit space of nasal cavity smaller than the diameter of the circular normal segment.

Devices for controlled administration of liquid solutions to nasal cavities and paranasal sinuses are disclosed. The proposed devices comprise an external housing defining an inner space and having a proximal and a distal end. The external housing comprises an air system for injecting air to a nostril plugs assembly; a pump system for pumping the liquid solution to the nasal cavities; a removable cartridge holding the liquid solution, connected to the pump system; and a nostril plugs system removably connected to the pump system. The nostril plugs system comprises a two-line resilient tube; a plug-in system connected to one of the resilient tube; and a nostril plugs assembly connected to the other end of the resilient tube. The proposed devices may be used for the treatment of respiratory diseases including the respiratory syndrome coronavirus 2 (SARS-CoV-2).

Systems, apparatus and methods related to improved otorhinologic irrigation and lavage comprising a drainage collector and one or more otorhinologic adapters, which are capable of coupling to an irrigation-liquid container.

The present disclosure illustrates a nasal aspiration and wash device which includes a shell member, a pump, a suction part and a spray part. The pump is disposed in the shell member. The suction part is disposed on the shell member and configured to flow external gas into the pump. The spray part is disposed in the shell member and configured to spray atomized liquid out. The suction part and the spray part are spaced apart from each other a distance. The nasal aspiration and wash device of the present disclosure is able to separately perform a nasal aspiration function and a nasal wash function without interfering with each other, and the user does not need to replace a functional assembly for using the two functions.

A device, a system and a method are provided to accurately apply a medically beneficial substance directly to a laterally or superiorly located paranasal sinus cavity. When the device is assembled with a solution in a reservoir, and inverted such that the reservoir is above an input apparatus and a housing, weight of the solution pushes down on a diaphragm creating a negative pressure on the diaphragm, which prevents air from entering the reservoir and prevents a liquid from flowing out of the reservoir. Applying a positive pressure to a bottom of the diaphragm causes the diaphragm to open and allows air to flow into the reservoir. When a user creates the positive pressure by exhaling air into the device the act of exhaling causes the user's choana to close. Thereby any solution introduced into the user's sino-nasal cavity will remain contained within the user's sino-nasal cavity increasing effectiveness of treatment and decreasing user discomfort including gagging, choking, and inner ear disturbance. When the positive pressure on the bottom of the diaphragm is removed, the flow of the liquid from the reservoir stops.

A cap and container assembly is disclosed which may be used for human body cavity irrigation or other liquid dispensing activities. The cap may include a first channel extending from a base through a neck portion to an opening in a tip portion of the cap. A side body defining a second channel may extend from the first channel near the neck portion of the cap to an opening at a distal end of the side body. An axial dimension of the tip portion may extend at an angle relative to an axial dimension of the neck portion. Liquid may flow out of the first channel under the influence of gravity and as a result of control of air flow into the second channel.
