Nasal Irrigation Apparatus and Kit

TECHNICAL FIELD

This disclosure relates to nasal irrigation. More specifically, this disclosure pertains to apparatus and solutions delivered thereby for nasal irrigation.

BACKGROUND

Air enters the human lungs through two primary routes, i.e., the nose and the mouth. Air enters the nose through two nostrils which are passages into the nasal cavity from which the air flows into the nasopharynx, then the laryngopharenx, then the larynx and through the trachea into the lungs.

Air is conditioned by filtering through hairs in the nostril and then humidified and warmed in the nasal cavity. The entire surface of the nasal cavity is generally covered with a blanket (i.e., layer) of mucus which entraps particulate matter removed from the air. During good health conditions, the mucus layer is slowly moved by ciliated columnar epithelial cells that line the nasal cavity, toward the pharynx where it passes into the esophagus and moved to the stomach where it is digested.

The nasal cavity comprises four paired paranasal sinuses i.e., (i) the maxillary sinuses which are directly connected to the nasal cavity and which separate and space from the nasal cavity, (ii) the ethmoidal sinuses, (iii) the sphenoidal sinuses, and (iv) the frontal sinuses. The paranasal sinuses are also covered with blankets of mucus that are moved slowly toward the pharynx and on into the stomach.

All individuals experience periods of nasal congestion during which their ability to breathe through their noses is significantly impaired due to excessive production and accumulation of mucal secretions and phlegm in the nasal cavity, the maxillary sinuses, and the pharynx. Congestion commonly occurs as a consequence of one or more of a viral infection of the upper respiratory tract, a bacterial infection of the upper respiratory tract, or an allergic reaction. Congestion is often accompanied by considerable physical discomfort associated with one or more of post-nasal drip, decreased sense of smell, ear aches, headaches, sore throat, malaise, muscle and joint aches, fatigue, cough, chest congestion, fever, chills and gastrointestinal maladies.

Among treatments used to lessen the discomfort associated with congestion is irrigation of the nasal cavity and the maxillary sinuses with a solution to flush away the excessive accumulations of mucal secretions and phlegm. There are many types of containers that have been used for delivery of nasal irrigation solutions. For example, resiliently squeezable cylindrical bottles and bulb-shaped bottles, and the like. Such resiliently squeezable bottles are typically connected to a spout having a tip at its distal end to insert into and plug a nostril opening so that the irrigation solution is forced into the nasal cavity with the bottle is squeezed. Other types of containers are those referred to as “teapot” containers having spouts with nasal tips for delivering irrigation solutions into users' nostrils when their heads are tipped back with the teapots held above their noses. Other types of container are provided with user-controlled hand-pumps to deliver irrigation solutions into their nostrils.

However, there are many problems associated with the apparatus used for delivery of irrigation solutions into users' nostril. For example, resiliently squeezable bottles are difficult for users to handle to comfortably and completely deliver the bottle contents into their nasal cavities. Regardless of the type of container used, the delivery process, in addition to uncomfortable operation, is messy and causes in spillage and dripping of the irrigation solution over the users' faces and their clothes. Furthermore, the containers used for delivery of nasal irrigation solutions require the user to tilt their head to one side or alternatively, to tilt their head back while self-administering the flow of irrigation solution into one nostril, further adding to the discomfort of and dissatisfaction with using such apparatus. Yet another problem is the necessity to clean and sterilize the containers and their spouts after each use so that bacterial and/or viral infections present in lavaged mucal secretions and phlegm are not re-introduced into the users' naval cavities.

SUMMARY

The embodiments of the present disclosure relate to an apparatus for nasal irrigation comprising a resiliently compressible bottle component, a spout having a proximal end for demountable engagement with the bottle component and a distal end for demountable engagement with a nasal tip, and at least one nasal tip for delivering a solution in the form of a stream, or a spray, or a misting.
