DETAILED DESCRIPTION

[0018] For purposes of this application, any terms that describe relative position (e.g., “upper”, “middle”, “lower”, “outer”, “inner”, “above”, “below”, “bottom”, “top”, etc.) refer to an aspect of the invention as illustrated, but those terms do not limit the orientation in which the aspect can be used.

[0019] Transmucosal delivery of nutrient supplements offers advantages over oral delivery when negative issues relating to the gastrointestinal tract, stomach, substance digestion and absorption, swallowing, protocol compliance, substance effectiveness, and other gastrointestinal metabolism problems are considered. The formulation or composition may include a nutritional supplement matrix fraction, (ii) a gas fraction, (iii) an enhancer fraction, (iv) a liquid fraction, and (v) a preservative fraction wherein the nutritional supplement matrix fraction, the gas fraction, the enhancer fraction, the liquid fraction, and the preservation fraction are all mixed or combined and treated to maintain a state of balanced suspension among the oxygen molecules for a specific duration of time before being dispensed from a canister. Furthermore, the composition may be in a compressed state in a canister before being dispensed. In another aspect, the formulation or composition would include a nutritional supplement matrix fraction, (ii) a gas fraction, (iii) an enhancer fraction, (iv) a liquid fraction, and (v) a preservative fraction wherein the nutritional supplement matrix fraction, the enhancer fraction, the liquid fraction, and the preservation fraction are all mixed or combined and stored separately from the gas fraction in a canister before being dispensed. Additionally, the nutritional supplements are formulated, treated, and mixed with the gas fraction. The gas fraction is oxygen to maintain a state of balanced suspension among the oxygen molecules for a specific duration of time after being dispensed.

[0020] Furthermore, the composition may be in a compressed state in a canister before being dispensed. The transmucosal delivery of the supplement matrix is more efficient when the composition is atomized. It allows the enhancer fraction of the composition to adhere more to the nutritional supplement to the mouth's mucosal membranes. The buccal mucosa offers a promising administration site for nutrients as it has a rich blood supply and is relatively permeable. The bioadhesion of the delivery system is crucial for delivering across the buccal mucosa. Saliva may wash the delivery method of the buccal region. To alleviate these hydrophobic patches have been used to hold the nutrient or medication being administered through the buccal mucosa. Buccal spray devices have been used to deliver insulin in a mist of fine droplets onto the mucin layer of the mucosal membrane. Without a hydrophobic coating to protect the desired deliverable from the saliva, it is crucial to atomize the mixture and deliver it at a high velocity directly onto the buccal mucosa to maximize the amount of deliverable that is absorbed.

[0021] FIG. 1 is a perspective view of a first nozzle housing 100 for delivering an atomized mixture of oxygen and nutritional supplements into a mouth of a user for transmucosal delivery. FIG. 2 illustrates a system for delivering a composition to the oral mucosa 116 with the nozzle housing 100 affixed or engaged to a top of a canister 120 containing the nutritional supplements under pressure. In this aspect, a lower opening 101 of the nozzle housing 100 is engaged to the canister 120. The nutritional supplement passes from the canister 120 to the nozzle housing 100. The lower opening 101 may engage an outlet of the canister 120.

[0022] The nozzle housing 100 includes an outlet 102 that allows the atomized mixture or aerosol to exit the nozzle housing 100 and enter the user's mouth. The nozzle housing 100 may include any of many nozzle shapes known in the art that can adjust the spray pattern into the mouth for transmucosal delivery. For example, the nozzle housing 100 may provide a flat fan, full cone, hollow cone, solid stream, etc.

[0023] A rotating member 104 is positioned within the nozzle housing 100 between the canister 120 and the outlet 102. The rotating member 104 is affixed to the nozzle housing 100 by a support member 106. In the aspect FIG. 1, the support member 106 is located near a base 110 of the nozzle housing 100, which is close to the canister 120. The support member 106 extends across a width of an interior of the nozzle housing 100. The rotating member 104 is rotatably engaged to the support member 106. In this aspect, the rotating member 104 is affixed to an axle on the support member 106 that allows the rotating member 104 to spin inside of the nozzle housing 100 to agitate the composition being propelled into the mouth. The rotating member 104 may include multiple blades rotating in a lower cavity 114 of the nozzle housing 100. The lower cavity 114 is fluidly connected to the outlet 102 such that the nutritional supplements pass from the lower cavity 114 upward to the outlet 102.

[0024] The agitation of the composition by the rotating member 104 will further atomize the composition being propelled into the mouth, allowing for better absorption of the composition through the oral mucosa. When a mucoadhesive, such as apple pectin, is incorporated into the formulation, the droplets will be more prone to agglomeration. Incorporating the rotating member 104 or fan element into the nozzle housing 100 will further break up the agglomerated particles. The rotating member 104 will allow for better atomization of the formulation to increase absorption through the buccal mucosa and prevent the nozzle outlet 102 from clogging with agglomerated particles. The design, angle, and the several blades in the rotating member 104 may be optimized for this purpose. In this aspect, the rotating member 104 has its blades positioned to cause the rotating member 104 to spin when the compressed air is released from the canister. The blades of the rotating member 104 may be angled to ensure the canister's best atomization of the material. In certain aspects, a direction of rotation of the rotating member 104 may be generally perpendicular to a flow-path of the composition.

[0025] FIG. 3 illustrates a second nozzle housing 150. A cross-section of second nozzle housing 150 shows a smaller variation of the rotating member 104 connected to the support member 106 in an interior 152 of the second nozzle housing 150. The rotating member 104 is located in an upper cavity 154 of the second nozzle housing 150 close to the outlet 102. The upper cavity 154 is over a lower cavity 158 of the second nozzle housing 150.

[0026] The upper cavity 154 has a smaller internal diameter than an internal diameter of the lower cavity 158 of the second nozzle housing 150. Thus, the interior 152 of the second nozzle housing 150 tapers inward in the upward direction—in the direction of the outlet 102. A rear portion of an outlet housing is fluidly connected to the upper cavity 154. By positioning the rotating member 104 in the narrower upper cavity 154, the rotating member 104 performs more rotations per minute under the same amount of pressure compared to the aspect illustrated in FIG. 1. Greater RPM may further atomize the composition or achieve a similar RPM to the rotating member in FIG. 1 with a lower amount of air pressure from the canister. Positioning the rotating member 104 in a narrow portion of the nozzle housing 100, i.e., the upper cavity 154, may allow for greater air velocity, with the same canister air pressure, at the point of contact with the rotating member 104 due to the narrowing of the nozzle housing 100.

[0027] FIG. 4 illustrates a third nozzle housing 200 having a dual fan aspect. In this aspect, a second rotating member 104b is affixed to the opposite side of the support member 106 with a connection, through the support member 106, to a rotating member 104a. In this aspect, the two rotating members 104a and 104b have the same size and orientation. The second rotating member, 104b in this aspect, serves to further agitate the composition to aid in atomization. The angle and number of fan blades on each of the rotating members 104a and 104b may be adjusted to increase the composition's velocity and atomization. In other aspects, the fans may rotate independently of one another. In still further aspects, the fans may be of differing sizes. Two different size rotating members 104a and 104b may allow for one rotating member 104a to drive the rotation of the second rotating member 104b, allowing the second rotating member to rotate at a speed that exceeds the rate it would achieve based on its shape under the amount of pressure produced by the canister. In still further aspects, one or both of the rotating members 104a and 104b may be actively powered. Power may be supplied by a battery and actuator or through the mechanical movement of the nozzle housing 100 to the canister.

[0028] FIGS. 5A and 5B illustrates a fourth nozzle housing 250 in which the rotating member 104 is located after the outlet 102 of the aerosol. The fourth nozzle housing 250 emits the aerosol from the outlet 102, and then then the aerosol passes through the rotating member 104. The fourth nozzle housing 250 may include an additional structure to direct the flow path of the aerosol into the mouth of the user. As shown in FIGS. 5A and 5B, the fourth nozzle housing 250 includes a tubular member 254. The tubular member 254 is positioned over the outlet 102. A portion of the outlet 102 may extend in the tubular member 254. A proximal end 260 of the tubular member 254 is connected or integral with the fourth nozzle housing 250. A distal end 264 of the tubular member 254 includes an opening 270 to permit the flow of the aerosol to the user. In this aspect, the support member 106 may extend across an inner diameter of the tubular member 254. The support member 106 may engage opposites side of an interior of the tubular member 254. The support member 106 positions the rotating member 104 in the flow path of the aerosol. After the aerosol is emitted from the outlet 102, the aerosol passes through the rotating member 104, and then to the user.

[0029] In other aspects, the rotating member 104 may be positioned to accelerate the flow of particles into the mouth to increase the penetration into the buccal mucosa. The rotating member 104 may also be oriented to direct the flow of atomized droplets to the mouth's proper regions. For example, the rotating member 104 could be tilted downward to allow the user to control the spray more easily to one side of their mouth or the other and avoid spraying into the back of the throat where the nutritional absorption may be less efficient. To achieve the same benefit in a single spray, a pair of rotating members 104 could be positioned in the nozzle housing 100, each angled out to allow the user to spray directly into the mouth and have the rotating members 104 direct the droplets away from the back of the throat and towards the buccal region.

[0030] The nozzle housings described herein may also be used sprays that manually pressurize the liquid composition. For example, pump sprayers or trigger activated sprayers may develop sufficient PSI to dispense an aerosol. The rotating members and fans described herein may be utilized with such sprayers to increase atomization and reduce agglomeration.

[0031] The canister 120 may contain a supplement fraction, a gas fraction, an enhancer fraction, a liquid fraction, and a preservation fraction under pressure.

[0032] The supplement composition may include a combination of electrolytes, vitamins, and/or minerals.
