Patent Application
20110137258
The subject technology generally relates to nasal and sinus rinse procedures and apparatus and, in particular, to a nasal rinse system.
Existing sinus rinse devices usually include a tube in an upright dispenser, or irrigator, to siphon solution from the bottom of the upright dispenser, through an opening in the top of the upright dispenser as a user squeezes the sides of the upright dispenser during nasal irrigation.
Nasal and nasopharyngeal cavities are common places for holding environmental allergens and contaminants, such as pollen, fungal spores, animal body-originating dustings, dust, soot, ash, bacteria, viruses and the like. A nasopharyngeal system protects the nasal system by trapping such contaminants and allergens. These contaminants and allergens may be trapped by a system of mucous lined passageways. These contaminants and allergens may cause allergic reactions and other health consequences. The nasopharyngeal system is not self-cleaning and as a result, many disease-causing agents such as contaminants or allergens exist in the nasal and nasopharyngeal cavities. Hence, a need efficient means for cleaning the nasopharyngeal system.
As used herein, the term “sinus rinse device” is defined broadly and can include devices that may rinse or supply fluid to a nasal cavity, nasopharynx, oropharynx, oral cavity, or one or more paranasal sinuses. The technique of using a tube to siphon a solution from a solution is undesirable because it does not allow the user to completely empty the dispenser during normal use. Further, the tube is an additional component that can reduce the overall reliability and functional life of the dispenser. For example, the dispenser cannot be operated by the user as intended if the tube becomes defective. An additional process is required to detach, clean, and re-attach the tube to the sinus rinse product. The tube is susceptible to damage during the detaching, cleaning, and/or re-attaching process thereby rendering the sinus rinse product non-functional.
Further, the tube is a natural trap in which bacteria and/or mold can colonize and potentially infect the user. It is not uncommon for black mold to accumulate in the tube of the sinus rinse product and the possibility of pseudomonas bacteria developing in the tight-fitting areas where the tube attaches to a nozzle of the sinus rinse product is of concern to some physicians. Furthering the risk is the chance of some users not cleaning the tube with any frequency thereby increasing the chances for infection with each subsequent use. Furthermore, due to the Venturi Effect created by the tube on such sinus rinse products, the reflux action caused by the re-expansion of the dispenser, causes upper respiratory secretions including infected materials to be siphoned from the patient's nasal passages, back into the patient as they continue to irrigate their nasal cavity.
In one aspect of the disclosure, a nasal rinse apparatus may comprise a container and a dispenser. The container may comprise flexible walls or sidewalls having a proximal section and a distal section. The distal section configured to terminate at an upper surface. At least a first portion of the container tapers from proximally to distally to a maximum height at the upper surface and at least a second portion of the container tapers from proximally to distally to a minimum height at the upper surface. Other portions of the container, between the first and second portions, taper from proximally to distally to a height at the upper surface that is between the maximum height and the minimum height. A container connection portion may be disposed at the upper surface of the container. The container connection portion comprises a container connection cavity defining a principal connection axis. The container connection portion also defines an inclination angle between the principal connection axis and a primary long axis of the container. The primary long axis extends through the proximal and distal sections of the container. The dispenser comprises an interior cavity in fluid communication with the container, a proximal opening and a distal opening. The distal opening forms an aperture configured to deliver a fluid from the container into a nasal cavity of a user. A dispenser connection portion is at a proximal region of the dispenser where the dispenser connection portion is configured to couple to the container connection portion. When fluid in the container is ejected from the dispenser through the aperture, the fluid forms a jet trajectory primarily along a jet axis. The jet axis forms an angle of between about 80 and about 100 degrees with respect to the principle connection axis of the container connection portion.
Some embodiments include a nasal rinse apparatus comprising container, having flexible sidewalls and comprising a proximal section and a distal section; wherein the distal section terminates at an upper surface, at least a first portion of the container tapers from proximally to distally to a maximum height at the upper surface, at least a second portion of the container tapers from proximally to distally to a minimum height at the upper surface; wherein other portions of the container, between the first and second portions, taper from proximally to distally to a height at the upper surface that is between the maximum height and the minimum height; a dispenser disposed at the distal end, comprising an interior cavity in fluid communication with the container, a proximal opening and a distal opening, the distal opening forming an aperture configured to deliver a fluid from the container into a nasal cavity of a user; and wherein, when fluid in the container is ejected from the dispenser through the aperture, the fluid forms a jet trajectory primarily along a jet axis, the jet axis forming an angle of between about 70 degrees and about 110 degrees with respect to a principle axis orthogonal to the upper surface.
In some embodiments, the angle is between about 80 degrees and about 100 degrees. In some embodiments, the angle is about 90 degrees.
In some embodiments, the container further comprises a container connection portion disposed at the upper surface, the dispenser further comprises a dispenser connection portion, wherein the container connection portion is in fluid communication with, and couples with, the dispenser connection portion.
In some embodiments, the dispenser connection portion has a substantially circular cross section having an outermost circumference, and wherein at least part of the dispenser extends laterally beyond the circumference. In some embodiments, a latitudinal cross section of the aperture is eccentrically positioned with respect to the circumference.
In some embodiments, the nasal rinse apparatus is configured to have the dispenser positioned lower than the container during delivery of the fluid from the container into the nasal cavity of the user.
In some embodiments, when the nasal rinse apparatus is configured such that when the dispenser is positioned lower than the container, fluid flows through the aperture due to gravity.
In some embodiments, when fluid is in the container and when the flexible sidewalls are squeezed such that fluid pressure rises in the container, the fluid is ejected through the aperture.
In some embodiments, an inclination angle between the principal axis and a primary long axis of the container is between about 5 and about 70 degrees.
In some embodiments, an inclination angle between the principal axis and a primary long axis of the container is between about 20 and about 30 degrees.
In some embodiments, an inclination angle between the principal axis and a primary long axis of the container is about 25 degrees.
