Sino-nasal rinse delivery device with agitation, flow-control and integrated medication management system

Abstract

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.

Description

TECHNICAL FIELD

Embodiments of the present disclosure relate to nasal and sinus devices. More specifically, embodiments of the disclosure relate to delivering an solution/substance to the nasal and sinus cavities.

BACKGROUND

Paranasal sinuses are cavities formed within the bones of the face that are accessible via an individual's nasal cavity. The paranasal sinuses include the frontal sinuses, the sphenoid sinuses, the ethmoid sinuses, and the maxillary sinuses. Sino-nasal anatomy includes bilateral inferior, middle and supreme turbinate and the midline nasal septum. The paranasal sinuses and nose are lined with mucous-producing respiratory epithelial tissue.

Normally, mucous produced by the linings of the sino-nasal sinuses slowly drains out of each sinus through an opening known as an ostium. Some conditions, however, can interfere with the drainage of the mucous. A healthy sino-nasal condition depends upon proper mucous drainage from the sinus cavities and the nose. When this natural process is disrupted by the effects of allergen, other bioactive particulate matter deposits or abnormal anatomic variations a condition of mucous stasis in the sinus cavities or the nose. As a consequence, nasal lining mucositis and/or sino-nasal disorders (e.g., a sinus infection, sinus headache, epistaxis, nasal obstruction, rhinorrhea) can result. Some of the conventional systemic approaches to treating these disorders often result in cutaneous rash, diarrhea, bacterial resistance from antibiotic use, adrenal suppression, weight gain from steroid medications, hypertension, sleep disturbance from decongestant use, epistaxis, headache, vertigo and others.

Surgery that is performed on the paranasal sinus cavities results in altered, modified or otherwise widened sinus drainage pathways compared to native outflow tracts.

Direct application of a substance to a sinus through a nasal cavity may avoid some of the side-effects listed above that are inherent in a systemic approach to treating sinusitis, rhinitis and/or mucositis.

However, due to the lateral or superior location of sinus outflow tracts the introduction of a substance via a trans-nasal route may result in a large majority of the substance bypassing the intended sinus cavity ostia.

More specifically, the post-surgical maxillary sinus ostia is located on the lateral nasal wall approximately 3.0 to 4.0 centimeters from the apex of the external nasal vestibule and approximately at a 45 degree angle with respect to the floor of the nose. Thus, a substance delivered using a device introduced into the nose at approximately 45 degrees from the floor of the nose with an approximate length of 3 to 4 centimeters and with the capability of directing a substance at an 80 to 90 degree angle relative to the device itself would have the capability of directly delivering a substance to the maxillary sinus cavity when properly oriented.

Additionally, the post-surgical frontal sinus outflow tract is located superiorly in the nasal cavity at approximately 5 to 6 centimeters from the apex of the external nasal vestibule at approximately 75° to 85° relative to the floor of the nose. Thus, a substance delivered using a device introduced into the nose at approximately 45 degrees from the floor of the nose with an approximate length of 3 to 4 centimeters and with the capability of directing a substance at an 80 to 90 degree angle relative to the device itself would have the capability of directly delivering a substance to the frontal sinus cavity when properly oriented.

Accordingly, there is a need for a device, system, and method of treatment that has the capability to quickly and accurately apply a substance directly to a laterally or superiorly located paranasal sinus outflow tract. The present disclosure discusses a device that satisfies such needs, among the others delineated.

Direct application of a substance to an infected sinus through a nasal cavity will avoid some of the side-effects listed above that are inherent in a systemic approach. However, the introduction of a substance via a trans-nasal route may result in a large majority of the substance flowing down the individual's throat, resulting in possible aspiration, coughing and or choking; if the substance enters the oral cavity it also is distasteful, which further exacerbates the unpleasantness. Additionally, if a substance is forcibly introduced into a nasal cavity it is possible to overcome physiologic proximal Eustachian tube resistance resulting in the substance contaminating the middle-ear. The presence of a substance (other than physiologic body-temperature aeration) in the middle-ear may result in aural fullness, otitis effusion, otitis media, hearing loss (possibly permanent), ossicular chain injury, damage to the middle-ear mucosal lining, dizziness/unsteadiness, nystagmus, nausea and others.

Accordingly, there is a need for a device and/or system that has the capability to quickly and accurately apply a substance to a paranasal sinus and/or sino-nasal cavity, prevent the substance applied to a paranasal sinus and/or sino-nasal cavity from flowing down a patient's throat and/or prevent the substance from contaminating the middle-ear cavity. The present disclosure discusses a device that satisfies such needs, among the others delineated.

Agents used in medicated sinus lavage are commonly supplied in capsule or other form; many individuals with dexterity problems are unable to manage the delivery of medication supplied in capsule or other form into sinus irrigation solution.

With respect to solubility of agents administered as a sinus lavage, there exist a category of agents that are immiscible in an aqueous or saline environment therefore presenting a challenge to delivery of a consistent agent concentration.

The use of saline or other sino-nasal irrigation solution delivered in a non-linear, turbulent, or pulsatile manner provides potentially additional cleansing properties over a solution delivered as a constant, uniform stream.

The effective use of gravity-assist sino-nasal lavage can be limited by an inability to control the flow of irrigation solution due to the siphon effect, i.e. a tube used to convey liquid upwards from a reservoir and then flows down to a lower level due to gravity, once the liquid has been forced into the tube and elevated, flow continues unaided and cannot easily be controlled or stopped.

The effective use of gravity-assist sino-nasal lavage can be further limited by an inability to extend the neck and look upwards, as is required in the application of conventional sino-nasal irrigation systems that rely on gravity to dispense the solution. This limitation is particularly acute for persons with neck extension limitations or persons who experience dizziness in this position, in particular elderly persons.

Sino-nasal rinsing can be limited by design features that are selective for specific anatomy, specifically that of adult versus children.

SUMMARY

Embodiments of the disclosure relate to delivering a pharmaceutically acceptable buffer preferably consisting of sterile saline solution or a solution with a therapeutically effective concentration of a pharmaceutical to nasal and sinus cavities. While multiple embodiments are disclosed, still other embodiments of the present disclosure will become apparent to those skilled in the art from the following detailed description, which shows and describes illustrative embodiments of the disclosure. Accordingly, the drawings and detailed description are to be regarded as illustrative in nature and not restrictive.

The sino-nasal irrigation device consists of a reservoir container; a housing with a grinding chamber and nose piece; and an input apparatus with a mouth piece. The reservoir container is intended for holding an solution. The housing has a grinding chamber for crushing capsules, pills, and the like, with an integrated filter separating the grinding chamber and the reservoir container that allows ground material of a predetermined size to pass through the filter and into the reservoir container. The housing also has a nose piece with a nasal tip and an optional nasal tip extension.

When the sino-nasal irrigation device is assembled with a solution in the reservoir container, and inverted such that the reservoir container is above the input apparatus and the housing, the weight of the solution in the reservoir container pushes down on the diaphragm creating a negative pressure on the diaphragm. The weight of the solution on the diaphragm prevents air from entering the reservoir container and thus prevents solution from the reservoir container from flowing out through the nose piece. Applying a positive pressure to the bottom of the diaphragm causes the diaphragm to open and allows air to flow into the reservoir container. The air flowing into the reservoir container causes turbulence in the solution held in the reservoir container resulting in the mixing of the air and solution. The air flowing into the reservoir container also allows the solution in the reservoir container to flow out of the reservoir through the nose piece and into a user's nasal cavity. When the positive pressure on the bottom of the diaphragm is removed, the flow of liquid from the reservoir container stops.

Sino-Nasal Irrigation Device

Referring to FIGS. 1 to 9, the sino-nasal irrigation device (100) consists of a reservoir container (110), a housing (120) that is removably connected to the reservoir container (110) having a grinding chamber (125), a nose tube (150), and an input device (170) that is removably connected to the housing (120).

The reservoir container (110) in the preferred embodiment has a hollow interior cavity adapted to contain an solution and has a base (112). The reservoir container (110) has a curved sidewall (115) that extends substantially perpendicular to the base (112) to the open top (117) of the reservoir container (110) thereby defining the hollow interior cavity. The reservoir container (110) is adapted to removably engage the housing (120). In the preferred embodiment the reservoir container (110) has male threads (118) to threadingly mate with the housing (120). The reservoir container (110) may be of any shape or size including a round bulbous shape, a square or a rectangle.

The housing (120) is removable attachable to the reservoir container (110). In the preferred embodiment the housing (120) has female threads (124) to threadably mate with the reservoir container (110). The top of the housing (122) has a grinding chamber (125) and a nose piece aperture (140). The grinding chamber (125) has a sidewall (128) that is preferably curved and extending substantially perpendicular to the top of the housing (122). The grinding chamber (125) has a filter (135) at the base that is integrated into the housing top (122) consisting of a plurality of holes (138) that will allow ground material of a defined size and water or a solution to pass through the filter (135). The plurality of holes (138) may be of uniform size or varying size. In the preferred embodiment the plurality of holes (138) are of varying size ranging from ⅛^th of an inch in diameter to 3/16^th of an inch in diameter.

In an alternative preferred embodiment other substances including powders, liquids, gaseous and vapors may be introduced into the reservoir container (110) through the filter integrated into the grinding chamber (135) or by bypassing the grinding chamber (125) and introduced directly into the solution in the reservoir container (110). In an alternative preferred embodiment a vapor pod (not shown) may be removably attached to the air tube (180) so that when a user exhales into the mouth piece (185) on the input apparatus (170) air and vapor from the vapor pod creates a positive pressure in the air tube (180) and air and vapor passes through the diaphragm (190) and into the reservoir container (110) where the vapor mixes with and dissolves into the solution. The introduction of air and vapor into the reservoir container (110) displacing the solution held in the reservoir container (110) out the nose tube (150) through the nasal tip (160).

The grinding chamber (125) also has a plurality of grinding teeth (130) that extend substantially perpendicular to the filter (135). The plurality of grinding teeth (130) may be of either uniform size and shape or varied size and shape. In the preferred embodiment the plurality of grinding teeth (130) consist of a plurality of cured grinding teeth (131) spaced equal distantly in a circular pattern in the grinding chamber (125) and a plurality of wedge shaped grinding teeth (132) located within the circular pattern formed by the curved grinding teeth (131).

The nose tube (150) is attached to the nose piece aperture (140) in the housing top (122). In the preferred embodiment the nose piece aperture (140) is a curve-linear oval shape. The nose tube (150) is preferably substantially rigid and curved such that when the sino-nasal device (100) is inverted the mouth piece (185) is proximate a user's mouth then the distal end of the nose tube (150) is proximate a user's nose bench. The nose tube (150) has a removable nasal tip (160) at the distal end of the nose tube (150). The nasal tip (160) frictionally engages the nose tube (150) and thus is adjustable and may be positioned in a preferable location for each user. The nasal tip (160) may be removed from the nose tube (150) for cleaning or replacement. The nasal tip (160) has various sizes and shapes (160a-160c) to accommodate the customary nasal opening sizes of children (160a), adults (160b), and larger adults (160c).

An alternative preferred embodiment may include a nasal tip for directional flow (167) that frictionally engage the nose tube (150) or the nasal tip aperture opening (165) to provide for a more controlled and direction application of medicine and/or solution to a surgical site, wound, or by user preference. The nasal tip for directional flow (167) is preferably flexible with a blunt terminal end (168) with a plurality of aperture openings (169) proximate to the terminal end that are preferably 2 to 4 mm in length and more preferably 1 to 2 mm in length. The plurality of aperture openings (169) are preferably oval, but may also be substantially circular or substantially square in order to provide a desired flow rate of solution in a preferred direction. The nasal tip for directional flow (167) are preferably 1 to 4 cm length, and more preferably 1 to 2 cm length. The exposed length of nasal tip for directional flow (167) may also be controlled by how far the nasal tip for directional flow (167) is inserted on the nose tube (150), or alternatively, into the tip aperture opening (165) in order to maximize the delivery of medicine and/or solution to a surgical site, wound, or by preference of a user.

The input apparatus (170) is removably attached to the grinding chamber (125) on the housing (120). In the preferred embodiment the input apparatus (170) has a hollow interior cavity (177) that is threaded to connect to the exterior of the grinding chamber sidewall (128). When the input apparatus (170) is attached to the grinding chamber (125) the mouth piece (185) of the input device (170) should align with the nasal tip (160) of the housing (120) when assembled and closed. The input apparatus (170) is comprised of a mouth piece (185) that is frictionally attached to an air tube (180) so that the location of the mouth piece (185) may be configured in a preferred way for each user. The air tube (180) is also connected to the L-connector (175) of the input apparatus (170). In the preferred embodiment the air tube (180) connects in the center of the top of the L-connector (175) which is attached to the input apparatus (170). A diaphragm (190) is interposed at the terminal end of the air tube (180) where the air tube (180) connects to the input apparatus (170).

When the sino-nasal irrigation device is assembled with a solution in the reservoir container, the diaphragm (190) permits air into the reservoir container (110) when a positive pressure exists in the air tube (180) by allowing air to pass through the diaphragm (190). When a positive pressure does not exist in the air tube (180), then the diaphragm (190) prevents the flow of an solution in the reservoir container (110) from flowing pass the diaphragm (190) and out the input apparatus (170).

The mortar (200) has a first distal end (205) with a recess (210) containing a plurality of grinding teeth (205) and a second distal end (207) with a plurality of tines (prongs) (225) that are covered by a frictionally engaged cap (220). In the preferred embodiment the plurality of grinding teeth (215) in the recess (210) in the first distal end (205) consist of a plurality of curved grinding teeth (215) spaced equal distantly in a circular pattern in the recess (210) and a square pike grinding tooth (210) in the center of the recess (210). The second distal end (207) has a plurality of tines (225) that may be sized or of variable sizes. In the preferred embodiment, the size and placement of the tines (225) matches the aperture size and pattern of the plurality of holes (138) in the filter integrated into the bottom of the grinding chamber (135) to facility the cleaning of the grinding chamber (135) by dislodging any material caught in the integrated filter (135) by pushing the tines (225) into underside of the integrated filter (135) in the housing top (122).

Referring to FIGS. 11 to 14, in an alternative preferred embodiment the reservoir container (610) has a hollow interior cavity adapted to contain an solution and has a threaded base cap (615) to be removably connected to the reservoir container (610). The threaded base cap (615) can withstand direct radiant heating in the range of 75° F. to 150° F. and more preferably 80° F. to 110° F. without any chemical breakdown or leaching of the chemicals used to make the reservoir container (610) or threaded base cap (615). The threaded base cap (615) has a flexible barrier layer (630) that permits a temperature probe (730) from the base station (700) to extend into the reservoir container (610) without coining in direct contact with the solution in the reservoir container (610). The reservoir container (110) has a curved sidewall (115) that extends substantially perpendicular to the base (112) to the open top (117) of the reservoir container (110) thereby defining the hollow interior cavity.

The base station (700) contains a logic engine that permits a user to input the desired temperature a user wants the solution in the reservoir container (610) warmed to. The temperature probe (730) takes a temperature reading, and then compares that temperature reading to the input temperature. If the temperature reading is below the input temperature, then the logic engine provides power to the base station heating sources (720) in order to raise the temperature of the solution to the input temperature. Once the solution reaches the input temperature, the logic engine may reduce power to the base station heating source (720) or turn the base station heating source off. The logic engine will continue to measure the temperature of the solution through the temperature probe (730) and apply heat as needed to maintain temperature. The temperature probe (730) is preferably a thermistor, thermocouple or similar temperature measuring probe. The base station heating source (720) is preferably resistive heating coils but may be any known heating source known to one of ordinary skill in the art.

The alternative preferred embodiment may also have indirect stirring means such as a magnetic stirrer consisting of one or more magnets in the base station and at least one magnet in the reservoir container that may be used to stir the solution to aid the dissolution of difficult to dissolve chemical compounds into solution.

The alternative preferred embodiment may also include an ultra-violate (UV) light source proximately located adjacent to the reservoir container (610) that will sterilize the water in the reservoir container (610).

Method of Using the Sino-Nasal Irrigation Device

The sino-nasal irrigation device (100) may be used by filling the reservoir container (110) with the desired amount of water. Preferably, and recommended, sterile water is used. Alternatively, denatured water may be used. The housing (120) is then removably engaged on the reservoir container (110).

Optionally, if a user wants to use an aqueous saline solution, then the user may place capsule(s) containing the equivalent of 2.4 grains of sodium chloride (NaCl) per 10 ounces of water into the grinding chamber (125) on the housing (120). Then, while firming holding the reservoir container (110), the user engages the first distal end (205) of the mortar (200) with the grinding chamber (125) containing the capsule to grind the capsule and its contents to sufficiently fine size to pass through the filter integrated into the bottom of the grinding chamber (135). Preferably, grinding of a capsule is achieved by twisting the mortar (200) in the grinding chamber (125) while applying downward pressure. Thereby allowing the ground capsule to form an solution in reservoir container (110). If the plurality of holes (138) in the filter (135) have become occluded with remnants of the capsule, then the plurality of holes (138) should be cleared by removing the housing (120) from the reservoir container (110) and pushing the tines (225) on the second distal end of the mortar (207) through plurality of holes from the underside of the integrated filer (135) in the housing top (122) to dislodge any material occluding the filter holes (135). The housing (120) is then removably engaged on the reservoir container (110). In an alternative preferred embodiment other substances including powders, liquids, gaseous and vapors may be introduced into the reservoir container (110) through the filter integrated into the grinding chamber (135) or by bypassing the grinding chamber (125) and directly into the substance into the reservoir container (110), thereby creating an solution.

The input apparatus (170) may then be removably engaged on the housing (120). The mouth piece (185) of the input apparatus (170) is aligned with the nasal tip (160) on the housing (120). The sino-nasal irrigation device (100) is then ready for treatment application.

The sino-nasal irrigation device (100) is then inverted such that the reservoir container (110) is above the input apparatus (170) and the housing (120), the weight of the solution in the reservoir container (110) pushes down on the diaphragm (190) creating a negative pressure on the diaphragm (190). The weight of the solution on the diaphragm (190) prevents air from entering the reservoir container (110) and thus prevents liquid from the reservoir container (110) from flowing out through the nose tube (150). Applying a positive pressure to the bottom of the diaphragm (190) causes the diaphragm to open and allows air to flow into the reservoir container (110). The air flowing into the reservoir container (110) causes turbulence in the solution held in the reservoir container resulting in the mixing of the air and solution. The air flowing into the reservoir container also allows the liquid in the reservoir container (110) to flow out of the reservoir (110) through the nose tube (150) and into a user's nasal cavity. When the positive pressure on the bottom of the diaphragm (190) is removed, the flow of liquid from the reservoir container (110) stops.

When a user, blows or exhales against resistance, the user's soft palate/uvula elevates and contacts the posterior wall of the oro/nasopharynx, thereby closing the choana. This normal physiologic process effectively creates temporary anatomic isolation of the nasal cavity from the oral cavity, distal airway and glottis/proximal trachea. As such, any fluid that is introduced into the user's sino-nasal cavity, as described herein, will remain contained within a user's sino-nasal cavity, being directed out the contralateral sino-nasal cavity, and not travel into the user's distal airway, glottis/superior trachea.

In an alternative preferred embodiment, a user blows or exhales against resistance to close the choana by blowing into the mouth piece (185) on the input apparatus (170), but the tube (180) is partially constrained allowing only a fraction of the air exhaled by the user to reach the reservoir container (110), or is fully constrained such that none of the air exhaled by the user reaches the reservoir container (110). When a positive pressure is detected in the tube (180) due to a user exhaling then a small pump (not shown) is activated to pump solution from the reservoir container (110) out the nose tube (150). When the positive pressure is removed, the pump is deactivated and the flow ceases. This alternative preferred embodiment may be used by those with compromised respiratory systems due to illness or other infirmity.

Referring to FIG. 10, a method for using the preferred embodiment is provided for treating a patient (700). Block 710 provides for adding a prescribed amount of sterile, or purified, water to the reservoir container (110). Block 720 provides for the partial assembly of the sino-nasal irrigation device by removably connecting the housing (120) to the reservoir container (110). Block 730 grinding of a capsule, tablet, or the like in the grinding chamber (125) to form a powder fine enough to pass through the filter (135). Block 740 provides for the forming of a solution by allowing the ground powder from the capsule, tablet, or the like to pass through the filter (135) and into the reservoir container (110) where the powder will be dissolved into the liquid to form a solution. Block 750 provides for the further assembly of the sino-nasal irrigation device by removably connecting the input apparatus (170) to the previously assembled reservoir container (110) and housing (120). Block 760 provides for the administration of the solution to a user by inverting the assembled sino-nasal irrigation device (100) so that the reservoir container (110) is above the housing (120) and input apparatus (170) such that any air remaining in the reservoir container (110) is proximate the base of the reservoir container (112), inserting the nasal tip (16) into a nostril of the user, and keeping the nasal tip inserted into a nostril of the user, blowing into the mouth piece (185) to provide a positive pressure in the air tube (180). The positive pressure in the air tube (180) causes air to pass through the diaphragm (190) and into the reservoir container (110) thereby displacing the solution held in the reservoir container (110) out the nose tube (150) through the nasal tip (160).
