DETAILED DESCRIPTION

[0027] In this description, the directional prepositions of up, upwardly, down, downwardly, front, back, top, upper, bottom, lower, left, right and other such terms refer to the device as it is oriented and appears in the drawings and are used for convenience only and such are not intended to be limiting or to imply that the device has to be used or positioned in any particular orientation. Additionally, where the word substantially is used, such is intended to be plus or minus twenty percent, unless otherwise defined upon such use.

[0028] Now referring to drawings in FIGS. 1-6, wherein similar components are identified by like reference numerals, there is seen in FIG. 1 a mode the device 10 formed in a unitary structure. In the mode of FIGS. 1-2, a capsule 12 is engaged to the distal end of a cylindrical housing 14.

[0029] An axial cavity 16 is positioned within the sidewall forming the cylindrical housing 14 and has an opening 18 communicating with the axial cavity 16 at a proximal end. The opening 18 allows for the insertion of a tampon 20 into the axial cavity 16.

[0030] In the mode of the device 10 of FIGS. 1-2, the capsule 12 is formed of a fluid-dissolvable material such as PCL, as is the sidewall forming the cylindrical housing 14. The dissolvable material forming one or both of the capsule 12 and cylindrical housing 14 may be impregnated with the desired medication or medications to be delivered to the vaginal canal during the dissolving of the capsule 12 and the cylindrical housing 14.

[0031] In a preferred mode to help prevent absorption of the fluid bearing the medication delivered by the dissolving capsule 12, the wall forming the cylindrical housing 14 is formed of a material mix calculated to dissolve more slowly than the capsule 12. In this fashion the medication from the capsule 12 is communicated to the vaginal canal before the tampon 20 is exposed to fluid flow therein. As noted, this prevents absorption of the medication by the tampons.

[0032] The capsule 12 may be formed in a solid solution of dissolvable polymer or other material which is impregnated with the medication, or it may be formed with a capsule cavity 22 which is surrounded by walls forming the capsule 12. Where the capsule cavity 22 is provided, dissolvable medication may be positioned within the capsule cavity 22 which will disperse into the vaginal canal once an opening forms in the wall of the capsule 12 as it dissolves.

[0033] As depicted in FIGS. 3-4, the device 10 may be formed with an engageable capsule 12, which is adapted to engage with a distal end of a cylindrical housing 14. This mode allows for doctors and pharmacies to stock multiple medications which are preferably delivered through the vaginal cavity, and engage them or provide them to the patient for engagement to the distal end of a cylindrical housing 16 surrounding a tampon 20. As can be discerned, capsules 12 having an infinite number of different medications may be stocked and provided which treat specific patient ailments, and may be engaged to a stock cylindrical housing 14. This allows for high customability of the capsules 12 which are impregnated with one or a plurality of medications which dissolve as the capsule dissolves.

[0034] Additionally, capsules 12 having a secondary supply of one or a plurality of medications may be provided where the capsule 12 is formed with a capsule cavity 22. This secondary medication supply may be pre-positioned within the capsule cavity 22, or for example, may be positioned therein by a medical professional using, for example, a hypodermic needle which is temporarily communicated through the wall of the capsule 12 surrounding the capsule cavity 22.

[0035] Finally, the removably engageable dissolving capsule 12 may be configured with mating connectors 24 or adhesive, which is configured to engage on or with the distal end of the cylindrical housing 14. Such, for example, might be pins or hooks which engage with the internally housed tampon 20, or might be projections which engage with connectors positioned on an endwall 26 at the distal end of the cylindrical housing 14. Where adhesive provides the mating connectors 24, such may engage the endwall 26 or might engage the internal surface of the axial cavity 16 if no endwall 26 is present.

[0036] Finally, FIGS. 5-6 depict a mode of the device 10 herein where the dissolving capsule 12 is adapted for an engagement with a medication such as the depicted tablet or capsule 15. In this mode, the tablet or capsule 15 of medication or supplement of choice shown in FIG. 5, is positioned within a slot 17 in the dissolvable capsule 12 which is adapted to engage it. Such might be, for example, by forming the sidewalls of the slot 17 to be flexible and forming the width of the slot smaller than most conventionally available tablets and capsules 15 used for medications and supplements. In use, the tablet or capsule 15 is slid into a compressive engagement within the slot 17 such as shown in FIG. 6. The medication and/or supplement provided in the capsule 15 will thus be delivered to the vaginal canal where it can dissolve.

[0037] It should be noted that any of the different depicted and described configurations and components of the device 10 employed in the system herein for vaginal drug delivery, can be employed with any other configuration or component shown and described as part of the device herein. Additionally, while the present invention has been described herein with reference to particular embodiments thereof and/or steps in the method of production or use, a latitude of modifications, various changes and substitutions are intended in the foregoing disclosure, and it will be appreciated that in some instance some features, or configurations, of the invention could be employed without a corresponding use of other features without departing from the scope of the invention as set forth in the following claims. All such changes, alternations and modifications as would occur to those skilled in the art are considered to be within the scope of this invention as broadly defined in the appended claims.
