     TECHNICAL FIELD 
       [0002]    The disclosure relates generally to a system and method of nasal aromatic compound delivery and specifically to a system for administration of therapeutic or pharmacologically beneficial essential oils by inhalation. 
       BACKGROUND 
       [0003]    Essential oils are known to have some therapeutic and pharmacological properties. Aromatherapy, for example, requires inhaling essential oil vapors, which are volatilized into the ambient air by heating a small amount of oil over a heat source, such as a candle. However, this has several drawbacks. First, because the oil disperses into the ambient air, the vapor is diffuse and lacks sufficient concentration for effective administration. Second, a candle is not convenient to use in most situations outside the home, and even if it were, all other persons present in the area would be forced to inhale the vapors from the oil. Last, heating essential oil has been shown to cause carcinogenic compounds to form from the oil or, at the very least, causes the oil to break down and lose some or all of its therapeutic or pharmacological properties. These drawbacks are undesirable.

     DETAILED DESCRIPTION 
       [0019]    Systems and methods of nasal aromatic delivery system and applications of the invention presented herein are described below in the drawings and detailed description of the invention. Unless specifically noted, it is intended that the words and phrases herein be given their plain, ordinary, and accustomed meaning to those of ordinary skill in the applicable arts. 
         [0020]    In the following description, and for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the various aspects of the invention. It will be understood, however, by those skilled in the relevant arts, that embodiments of the present invention may be practiced without these specific details. In other instances, known structures and devices are shown and/or discussed more generally in order to avoid obscuring the invention. In many cases, a description of the operation is sufficient to enable one of ordinary skill in the applicable art to implement the various forms of the invention. It should be appreciated that there are many different and alternative configurations, devices and technologies to which the disclosed inventions may be applied. The full scope of the present disclosure is not limited to the examples described below. 
         [0021]      FIG. 1  illustrates a nasal aromatic oil delivery system  100  according to a preferred embodiment. Nasal aromatic delivery system  100  comprises one or more of the following: body  102 , reservoir  104 , louvers  106 , fill port  108 , orifice  110 , accumulator chamber  112 , restrictor channel  114 , clip  118 , pad attachment hole  124 , channel  126 , outlet  128 , inlet  130 , arm  136 , and/or intake port  140 . 
         [0022]    Body  102  of nasal aromatic oil delivery system  100  comprises a durable and/or flexible material such as plastic, latex, silicon, rubber, or the like. In some embodiments, body  102  is transparent, translucent, opaque or a combination thereof. For example, body  102  comprises one or more windows  132  that allow the amount of odorant  120  inside reservoir  104  to be viewed from the outside. Alternatively, body  102  of nasal aromatic oil delivery system  100  may be entirely translucent or transparent to view the amount of odorant  120  inside reservoir  104  without one or more windows  132 . 
         [0023]    Body  102  is coupled with one or more clips  118  by one or more hinges  134  and/or arms  136 . In some embodiments, body  102 , clips  118 , hinges  134  and arms  136  comprise a single unit and/or are constructed of a single material. According to some embodiments, one or more of body  102 , clips  118 , hinges  134 , and/or arms  136  are constructed of one or more units and/or one or more materials such that hinges  134  provide a flexion point for clips  118  to secure tightly to inner surface  122  of nostril  152 . For example, body  102 , clips  118 , hinges  134 , and arms  136  may comprise a single piece of flexible plastic such that each clip  118  slides inside each nostril  152 , and each clip  118  secures tightly to the inner surface  122  of nostril  152 , with the force of the flexion of the one or more hinges  134  providing the force to hold nasal aromatic oil delivery system  100  securely inside of nose  150 . Arms  136  couple body  102  to hinges  134 . According to some embodiments, body  102  comprises the flexion point for nasal aromatic oil delivery system  100 . For example, in some embodiments, body  102  comprises a flexible material, such as rubber, plastic, or the like, which bends sufficiently to provide a force against an inner surface  122  of a nostril  152  to hold clips  118  securely to the inside of nose  150 . 
         [0024]    A further feature of this attachment is that the force of the flexion of nasal aromatic oil delivery system  100  or hinges  134  dilates the nostrils  152  to provide increased airflow through nose  150 , permitting easier breathing and inhalation of essential oils. 
         [0025]    According to some embodiments, nasal aromatic oil delivery system  100  comprises one or more exit channels  126 . Exit channels  126  permit an air passageway so that when the reservoir is being filled at one or more fill ports  108 , air may escape to outlets  128  from inlets  130  of reservoir  104  to permit easier refilling. In one embodiment, fill ports  108  are shaped to removably couple with a standard eyedropper. A standard eyedropper comprises a rubber bulb on one end connected to a small tube that ends with a pointed or rounded tip, which measures out liquid by drops. The pointed or rounded tip of a standard eyedropper typically comprises a surface that angles from the tube portion to the tip portion by an angle between 0 and 90 degrees, and typically between 0 and 60 degrees. This permits easy filling of reservoir  104  with standard essential oil vials, which typically contain a standard-sized eyedropper. In addition, or as an alternative, fill ports  108  comprise an angled surface, which mates with the outer angled surface of an eyedropper. For example, although eyedroppers comprise various shapes and sizes, embodiments contemplate fill ports  108  comprising a surface angled from approximately 0 to 60 degrees along the inner length of the accumulation chamber  112  such that any eyedropper would reversibly couple with fill ports  108 . Although, a standard eyedropper is described, embodiments contemplate any eyedropper or other essential oil vials, according to particular needs. 
         [0026]      FIG. 2  illustrates nasal aromatic oil delivery system  100  of  FIG. 1  in greater detail in accordance with the preferred embodiment. According to some embodiments, clips  118  may further comprise attachment holes  124 . Attachment holes  124  each comprise a hole configured to receive peg  202  coupled with pad  204 . Pad  204  is preferentially constructed of a soft material, such as latex, but may comprise any suitable material such as plastic, rubber, or the like. Pads  204  are sized to provide pad surfaces  206  that couple with inner surface  122  of nose  150  inside nostrils  152 . Various-sized and/or various-shaped pads  202  may be provided with nasal aromatic oil delivery system  100  such that pads  202  are customizable and comfortably fit into nostrils  152  of various shapes and sizes. In one embodiment, pads  202  comprise two lobes with a restricted surface between the lobes, such that a first lobe is placed on a first side of clip  118 , a second lobe is placed on a second side of clip  118 , and the restricted surface is placed inside the attachment hole  124 . 
         [0027]    Nasal aromatic oil delivery system  100  provides delivery of any substance from reservoir  104  by vaporization, volatilization, and/or evaporation. According to a preferred embodiment, reservoir  104  is fillable with an odorant  120 . Such odorants  120  may comprise one or more essential oils comprising therapeutic or pharmacological properties. The aromatic oil may comprise an essential oil such as, for example, oil of sweet orange, peppermint, cedarwood, lemon, eucalyptus, clove, spearmint,  Litsea cubeba, Menthe arvensis,  or the like. Additionally, embodiments of nasal aromatic oil delivery system  100  provide for odorant  120  to be placed in reservoir  104  for vaporization into nostril  152 , which enhances strength, stamina, mental alertness, and endurance, while reducing fatigue. Furthermore, the design of the present nasal aromatic oil delivery system  100  comprises a single reservoir  104 , which is fluidly coupled with both orifices  110  by a plurality of reservoir passages  138 . Because nostrils are different sizes and pull different amounts of air from each orifice  110 , the single reservoir design of the present invention ensures that single reservoir  104  provides vapor to both nostrils simultaneously, such that only one reservoir needs to be refilled—not a reservoir for each nostril individually. 
         [0028]    In addition, or as an alternative, reservoir  104  may be filled with a substrate, such as a resin, which absorbs a liquid odorant  120  placed in reservoir  104 . In this manner, spilling of odorant  120  is eliminated for at least the reason that odorant  120  will slowly evaporate from the substrate, while not being present in a spillable, liquid form. In some embodiments, odorant  120  is a liquid, solid, gel, or the like, comprising volatile odorant molecules, which are to be inhaled through nostril  152  of nose  150 . 
         [0029]    In some embodiments, the aroma from odorant  120  follows a pathway  200  from reservoir  104  into nostrils  152 . Odorant  120  in reservoir  104 , in a vapor or volatile form, flows from reservoir  104  along pathway  200  through reservoir passage  138  into restrictor channel  114 , through accumulation chamber  112 , out through orifice  110 , and into nostril  152 . In one embodiment pathway  200  comprises one or more of screen  116 , louvers  106 , and/or fill ports  108 . Although only one passageway  200  is shown, embodiments contemplate pathways  200  for each of the left and right orifices  110 . 
         [0030]    Accumulation chambers  112  are configured to sit slightly below each nostril in order to not obstruct air intake, but still permit inhalation of vapor of odorant  120  with each breath. Accumulation chambers  112  provide a chamber whereby odorant  120  is concentrated before inhalation. Although  FIG. 1  depicts an accumulation chamber  112  below each nostril  152 , embodiments, contemplate nasal aromatic oil delivery system  100  having only a single accumulation chamber  112 , according to particular needs. 
         [0031]    Intake port  140  provides an opening through which ambient air can enter into the accumulation chamber. Intake port  140  is configured such that when orifice  110  sits directly underneath nostril  152 , intake port  140  allows ambient air to enter into the accumulation chamber  112  which pushes the odorant into the nostril  152  when the pressure above the orifice  110  is decreased, such as with a breath. Ambient air, for purposes of this specification, means any gas, which is outside the device  100 , such as, for example, air in the atmosphere. 
         [0032]    Orifice  110  comprises an opening from the accumulation chamber  112  into nostril  152 . Orifice  110  comprises a shape suitable to sit below nostril  152  and to circumscribe an area of substantially the same shape as a nostril. As an example only and not by way of limitation, orifice  110  may comprise a circular, elliptical, or oval shape. According to some embodiments, orifice  110  is nostril-shaped, such as bean-shaped. According to some embodiments, orifice  110  comprises an oblong shape formed from joining one or more circles with one or more ellipses. According to some embodiments, a front surface of the perimeter of orifice  406  is higher than the back surface of the perimeter of orifice  408  (see  FIGS. 4A and 4B ) to permit nasal aromatic oil delivery system  100  to substantially contour to the three-dimensional shape of the surface surrounding the opening of the nostril  152 . 
         [0033]    Screens  116  provide a barrier to prevent foreign material other than odorant  120  from entering reservoir  104 . According to some embodiments, screens  116  comprise an extremely fine mesh which, when coupled with the high surface tension and/or viscosity of oil, prevents oil from leaking out of nasal aromatic oil delivery system  100  when jostled or placed on its side. 
         [0034]    Similarly, louvers  106  are constructed in a manner to permit odorant  120  to flow into reservoir  104  from fill port  108  and allow vapor or volatile odorant to flow into accumulation chamber  112 , but prevent oil from leaking out of nasal aromatic oil delivery system  100 . For example, according to some embodiments, louvers  106  comprise outward facing protrusions that form a helix along the inner surface of restrictor channel  114 . The helix permits odorant to be trapped between the protrusions, with the helix facing downward such that odorant cannot move past the protrusions when the system is in sideways position, but also permits the odorant to drain back along the helix into reservoir  104  when the system is placed in an upright position. 
         [0035]      FIGS. 3C and 3D  illustrate a top-down view of the louvers in a first position  302  and a second position  310 . According to some embodiments, louvers  106  comprise one or more movable structures such as semicircles or an aperture, which is adjustable to increase, decrease, open or close the restrictor channel. For example, as shown in  FIGS. 3A-3D , louvers  106  may be in a first position  302  when a switch is in a first position  306 . Louvers  106  may be moved to a second position  310  when a switch is moved to a second position  308 . Either the first or second positions of louvers  106  or switch may be a neutral, upward, or downward position according to particular needs. By way of example only and not by limitation, louvers  106  may be in a first position  102  sloping at a steep angle downward. This position permits reservoir  104  to be filled with an odorant  120  easily. Additionally or in the alternative, this position permits a greater amount of vapor to flow from reservoir  104  into nostril  152 . Continuing with the example, when louvers  106  are moved to a second position  308 , such as a less steeply inclined downward position, or a neutral position, odorant  120  may be prevented from passing through restrictor channel  114 . This would permit nasal aromatic oil delivery system  100  to be stored on its side without odorant  120  from leaking out. Furthermore, this would permit the amount of vapor flowing through restrictor channel  114  and into nostril  152  to be lessened. In this manner, the amount of vapor released by nasal aromatic oil delivery system  100  is controllable. 
         [0036]      FIGS. 3E-3H  illustrate an aperture according to an embodiment, used to control the amount of vapor and/or odorant flowing through nasal aromatic oil delivery system  100 . According to embodiments, rotation of a cuff  322  around the outer circumference of the aperture coupled to restrictor channel  114  increases or decreases the opening of the aperture. For example, an aperture may be in an open position  320  when the cuff is rotated in a first direction. The aperture may be in a closed position  324  when the cuff is rotated in a second direction. In this way, the amount of vapor passing through restrictor channel  114  can be precisely controlled, thereby controlling the amount of vapor entering into nostril  152 . Similarly, when the aperture is in a completely closed position odorant  120  may be securely stored inside nasal aromatic oil delivery system  100  even when the system is on its side or upside down. 
         [0037]      FIG. 3I  illustrates a cap for nasal aromatic oil delivery system  100  according to embodiments. A cap  340  comprises an upper portion  342  and a lip  344 . The lip  344  of cap  340  is configured to removably couple to orifice  110 , such as by a protrusion on the lip  344  or the inner surface of orifice  110 . In one embodiment, lip  344  snaps into an opposingly-positioned recess on the inner surface of orifice  110  or lip  344 , respectively. Alternatively, both the lip  344  of cap  340  and the inner surface of orifice  110  may comprise protrusions which, when slid past each other, cause the cap to be removably coupled to the inner surface of orifice  110 . Cap  340  prevents odorant  120  from spilling out of nasal aromatic oil delivery system  100  when nasal aromatic oil delivery system  100  is on its side or upside down. Additionally, cap  340  prevents odorant  120  from evaporating from nasal aromatic oil delivery system  100  when nasal aromatic oil delivery system  100  is not in use. 
         [0038]      FIG. 4A  illustrates a front view of nasal aromatic oil delivery system  100  coupled with nose  150  by clips  118  being inserted into nostrils  152 . From a front view, nasal aromatic oil delivery system  100  comprises a forward-facing front surface  402  and a back or reverse surface  404 . Also shown are a front surface of the perimeter of the orifice  406  and a back surface of the perimeter of the orifice  408  to permit the nasal aromatic oil delivery system  100  to substantially contour to the dimensions of nostril  152 . According to some embodiments, the front surface of the perimeter of the orifice  406  is shaped to couple to the front surface of nostril  152 , and the back surface of the perimeter of the orifice  408  is shaped to couple to the back surface of nostril  152 , as discussed herein. 
         [0039]      FIG. 4B  illustrates a side view of nasal aromatic oil delivery system  100  coupled with nose  150  by clips  118  being inserted into nostrils  152 .  FIG. 4B  illustrates nasal aromatic oil delivery system  100  comprising a front surface  402  and a back or reverse surface  404  coupled to nostril  152  by clips  118 . 
         [0040]      FIG. 5  illustrates an embodiment of a nasal aromatic oil delivery nasal aromatic oil delivery system  100  further comprising a nose clip  500 . According to this embodiment, nose clip  500  comprises a basket shaped in the form of a truncated cone. The basket comprises interspaced elements in longitudinal and latitudinal orientations to permit air to flow from orifice  110  into a nostril through spaces  504  at the top of nose clip  500 . A further feature of forming the basket of nose clip  500  in the shape of a truncated cone is that it dilates or expands the nostrils to provide increased airflow through a nose, permitting easier breathing and inhalation of essential oils. Nose clip  500  couples with nasal aromatic oil delivery system  100  via arms  136 , which may comprise any length such that orifice  110  is held directly below the nostril. 
         [0041]      FIG. 6  illustrates an embodiment of a nasal aromatic oil delivery system  100  comprising an interchangeable insert  600 . According to some embodiments, interchangeable insert  600  comprises an insert intake hole  602  and an insert restriction channel  604 . According to some embodiments, nasal aromatic oil delivery system  100  comprises an ambient air gap  610  and an odorant gap  612 . Ambient air gap  610  comprises a hole from orifice  110  and accumulation chamber  112  to the ambient air through a side surface of nasal aromatic oil delivery system  100 . Odorant gap  612  comprises a hole from accumulation chamber  112  through reservoir passage  138  to reservoir  104  (see  FIG. 1 ). Both ambient air gap  610  and odorant gap  612  are preferably sized larger than insert intake hole  602  and insert restriction channel  604 . When insert  600  is slid into accumulation chamber  112  the inset intake hole  602  couples to ambient air gap  610  and insert restriction channel  604  couples to odorant gap  612 . This coupling of insert  600  to accumulation chamber  112  provides the ability to adjust the amount of odorant or ambient air entering into accumulation chamber  112  (and thus into a nostril) by providing inserts with various shaped insert intake holes  602  and insert restriction channels  604 . By way of example only and not by way of limitation, embodiments contemplate providing nasal aromatic oil delivery system  100  with a variety of inserts  600  such that nasal aromatic oil delivery system  100  can be configured to provide various amounts of ambient air through insert intake holes  602  and various amounts of odorant through insert restriction channel  604 . Such usefulness permits adjusting the amount of vapor to provide more or less vapor according to the appropriate dose, strength or sensitivity associated with the odorant (such an essential oil) providing the vapor. Similarly, adjusting the amount of ambient air flowing into the accumulation chamber permits greater airflow through nasal aromatic oil delivery system  100  to provide an appropriate amount according to the respiratory needs of a user. 
         [0042]    According to some embodiments, inserts  600  comprise only an insert restriction channel  604 . By way of example and not by limitation, inserts  600  may comprise a shape that couples to accumulation chamber  110  sits below the position of an ambient air gap  610  or intake port  140  thereby allowing various inserts  600  to be supplied that will alter the size of the restriction channel  114  but does not alter the size of the intake port  140  (see  FIG. 1 ). 
         [0043]    According to some embodiments, inserts  600  comprise no insert intake holes  602  and no insert restriction channels  602 . An embodiment of an insert  600  with no holes provides a lid or closure such that odorant  120  does not flow out of leak from nasal aromatic oil delivery system  100  when insert  500  (see  FIG. 5 ) is inserted into the accumulation chamber  112 . 
         [0044]      FIG. 7  illustrates a nasal aromatic oil delivery system  100  in accordance with a sport personal diffuser  700  embodiment. Although, sport personal diffuser  700  is described as comprising one or more various features, as described below, embodiments contemplate sport personal diffuser  700  comprising any one or more features described in connection with nasal aromatic oil delivery system  100 . According to an embodiment, personal diffuser  700  may comprise a pair of wick cavity housings  702  coupled with a pillar  704  and a pair of internal nostril clips  706 . 
         [0045]    Internal nostril clips  706  permit sport personal diffuser  700  to be held firmly against the inside of a nose and to be properly positioned for maximum installation ease, comfort, and aroma vapor effectiveness. Internal nostril clips  706  may be coupled to wick cavity housings  702  by nostril clip tension regulators  730 . 
         [0046]    Nostril clip tension regulators  730  may comprise an internal ergonomically designed nostril clip tension regulator  730  that regulate holding pressure or tension of internal nostril clips  706  and may be designed to position wick cavity housing  702  for maximum essential oil aromatic vapor inhalation. 
         [0047]    Pillar  704  may couple the pair of wick cavity housings  702 . According to an embodiment, pillar  704  comprises an external nostril clip tension regulator and aerodynamic-enhanced design. Pillar  704  may add tension to the internal nostril clips  706  to hold sport personal diffuser  700  to inner nostril to position wick  800  ( FIG. 8 ) in its pre-ergonomic-designed position for maximum essential oil vapor inhalation. 
         [0048]    The pair of wick cavity housings  702  is designed to be aerodynamic and to hold a wick  800  inside wick cavities  708  situated substantially below a pair of nostrils. 
         [0049]      FIG. 8  illustrates a pair of wicks  800  comprising a width  802  and height  804  and designed to be secured inside wick cavity  708 . The width  802  and height  804  of wick  800  may be sized so as to fit within wick cavity  708 . The wicks  800  may comprise an absorbent substrate or resin, such as POREX™ porous polyethylene substrate, that has been imbued or saturated with an odorant  120 , such as essential oil or other vapor-releasing substance. The wick cavity  708  may comprise an internal cavity with a shape substantially similar to wick  800  or may be sized smaller or larger according to particular needs. Although the shape of wicks  800  and wick cavity  708  is described as having a particular shape, embodiments contemplate any shape and design of wicks  800  and wick cavities  708  according to particular needs. 
         [0050]    According to an embodiment, the wicks  800  comprise a semi-rigid material that permits the wick  800  to deform slightly so that the wick may be sized slightly larger than the wick cavity  708  and the pressure from the wick  800  pushing against the walls of the cavity  708  secure the wick  800  to the inside of the wick cavity  708 .

Wick cavities  708  may comprise ribs  720  and wick extraction channels  722 . Rib  720  may comprise a tolerance-regulating rib that secures wick  800  inside wick cavity  708 . The spatial tolerance of wicks  800  may comprise +/−0.012 inches. Rib  720  comprises a depth from the wall of the wick cavity  708  that is at least as great as the spatial tolerance of wick  800  such that the rib  720  holds the wick  800  securely inside the wick cavity  708  regardless of the precise wick  800  measurement. Although ribs  708  are indicated as being substantially at the side of the sport personal diffuser  700 , embodiments contemplate any suitable number of ribs  708  or position along the interior of wick cavity  708  according to particular needs. 
         [0053]    Wick extraction channels  722  of sport personal diffuser  700  may comprise a space or opening along the side of the wick cavity  708  that permits one or more of the following features: guiding a pick out tool for the removal or exchange of wick, cleaning and sterilizing sport personal diffusor  700 , replacement of wick  800 , and/or substitution of different types of odorants that are specific to the current situation. Although wick extraction channels  722  are indicated as being substantially at the front of the sport personal diffuser  700 , embodiments contemplate any suitable position along the interior of wick cavity  708  according to particular needs. 
         [0054]    Wick cavity housings  702  may further comprise enhanced vapor diffusion accumulation chambers  710 . Enhanced vapor accumulation chambers  710  permit opening or exposing more of a top surface of wick  800  for accumulating and collecting more aromatic vapor for increased inhalation of vapor. Enhanced vapor accumulation chambers  710  may comprise a cavity defined by the top of the edges of the wick cavity housing  702  down to the top and sides of the wick  800  that are not covered by the wick cavity  708 . Embodiments contemplate varying the sides of the wick cavity  708  to expose more or less of the wick  800  to the enhanced vapor accumulation chamber  710  to regulate the amount of diffusion of odorant  120  from wick  800 . For example, a larger enhanced vapor accumulation chamber  710  permits more rapid diffusion, whereas a smaller enhanced vapor accumulation chamber  710  permits slower diffusion. 
         [0055]    External portions of wick cavity housing  702  may comprise a directional force curve  712 , an aroma vapor directional funnel  714 , an induction offset curve  716 , and a rear edge  718 . 
         [0056]      FIG. 10  illustrates a directional force curve  712  and an induction offset curve  716  of a sport personal diffuser  700 , according to an embodiment. 
         [0057]    Directional force curve  712  comprises an offset widening towards the back of sport personal diffuser  700  and permits, as sport personal diffusor  700  is in forward motion, reduced wind resistance, a stabilized position of wick cavity housing  702 , and assistance in funneling aroma vapor up into nostrils, reducing vapor loss. According to some embodiments, directional force curve  712  comprises a surface that may be concave, convex, or a combination of both, that begins at the front  1002  and/or bottom  1004  of the wick cavity housing  702  and curves toward the back  1006  and/or top  1008  of wick cavity housing  702 . For example, embodiments contemplate a concave directional force curve  712  that uses the airflow from the front  1002  of the wick cavity housing  702  toward the back  1006  of the wick cavity housing, caused by a user moving in a forward direction, as pressure to hold the personal diffusor  700  substantially in proper alignment. According to some embodiments, directional force curve  712  comprises a curve from the bottom  1004  of the wick cavity housing  702  toward the top  1008  of the wick cavity housing  702  configured to direct air upward toward the nose of a user of personal diffusor  700 . According to some embodiments, directional force curve  712  comprises a combination of curves on the outer surface of wick cavity housing  702  to perform the functions just described. 
         [0058]    Aroma vapor direction funnel  714  comprises sides and the back of the top  1008  of the outer surface of wick cavity housing  702  to funnel vapor upward into nasal passage. 
         [0059]    Induction offset curve  716  permits adding an offset curve is an offset or dip in a front top curve of enhanced vapor diffusion accumulation chamber. According to an embodiment, induction offset curve  716  comprises an opening or recess on front  1002  surface of wick cavity housing  702  configured to permit increased airflow over wick  800 . 
         [0060]    Induction offset curve  716  may comprise an opening that dips below the top  1008  and front  1002  of wick cavity housing  702  or top surface of wick  800  so as to allow air induction or forcing of air as sport personal diffusor  700  is in a forward movement across wick  800  to enhance, forcing and always filling nostrils with aroma vapor even in between breaths. 
         [0061]    Rear edge  718  may be particularly effective when used on a “sports” version of the system  700  and is slightly higher or raised than the side edges to corral and funnel upward as air from induction offset curve  716  wants to force vapor toward rear and over rear curve to upper lip losing aroma vapor to environment and losing its effectiveness. According to some embodiments, rear edge  718  comprises a gradual increase in the size of side edges toward the rear of wick cavity housing  702 . 
         [0062]    A columellar pocket  724  comprises a height  726  and a width  728  designed to accommodate the height and width of a nasal columella. The columellar pocket  724  may be ergonomically designed to comfortably accommodate a typical columella or space between nostrils. 
         [0063]      FIG. 11  illustrates the personal diffuser  700  of  FIG. 7  in greater detail in accordance with an embodiment. Wick cavity housing  702  comprises ergonomically designed flat back  1102 . Flat back  1102  comprises a back  1006  surface of wick cavity housing  708  that is substantially flat and squared off to permit user comfort, safety, and protection in case personal diffuser is position altered or dramatically forced into a user&#39;s upper lip area. 
         [0064]      FIG. 12  illustrates a medical personal diffuser  1200  according to an embodiment. Medical personal diffuser  1200  comprises one or more features of sport personal diffuser  700  with differences, as described below. 
         [0065]    Medical direction force curve  1212  of medical personal diffuser  1200  comprises straight sides from medical aroma vapor directional funnel  1214  down to base of medical wick cavity housing  1202 . Medical personal diffuser  1200  may not comprise an induction offset curve  716 . The top surface of wick cavity housing  1202  comprises uniform sides so as to resemble a round complete funnel matching the high point of rear edge  1218 . Medical personal diffuser  1200  may not comprise aroma vapor direction funnel  714  or induction offset curve  716  permitting corralling and funneling aroma vapor up only as there will be no forward movement of medical personal diffuser  1200 . 
         [0066]    Medical personal diffuser  1200  may not comprise an enhanced vapor diffusion accumulation chamber  710 . Instead, the walls of wick cavity  1208  will be flat against the sides of wick  800  all the way to the top of the wick  800 . This permits diffusion from the top of wick  800  only, thereby permitting decreased vapor intensity and prolonging aroma vapor diffusion. 
         [0067]    As medical personal diffuser  1200  may not comprise an enhanced vapor diffusion accumulation chamber  710 , the walls of the wick cavity  1208  will cover the wick sides substantially completely in a medical personal diffuser  1200 . According to an embodiment, a medical personal diffuser  1200  comprises two tweezer or tweezer-like tool slots  1204  on top sides of wick cavity that are ⅛ inch across and 1/16 inch deep in which a tweezer or tweezer-like tool can be inserted down the top sides of wick  800  for the purpose of extraction. 
         [0068]    Embodiments also contemplate a youth personal diffuser that is a small-sized medical aromatic delivery system  1200  that has been decreased in overall size as to fit correctly and comfortably the smaller size of an adolescent nasal structure.
