Tampon with intravaginal cannabinoid delivery device

Abstract

A tampon and therapeutic delivery device is disclosed and includes a generally cylindrical applicator tube defining a cartridge within which a tampon is slidably received for ejection through one end of the cartridge. A generally hollow cylindrical plunger member is slidably received within an opposite end of the cartridge for ejecting the tampon therefrom. A cannabinoid-infused disintegrable carrier material is partially embedded in and movably held by the tampon for intravaginal delivery when ejected from the cartridge, whereupon the cannabinoid agent is released into the vagina and absorbed through the vaginal mucosa to provide relief of dysmenorrhea. The cartridge has a plurality of slots to permit pre-lubrication of the tampon, if desired, prior to insertion into the vaginal cavity. The system delivers a higher concentration to the muscle of the uterus, the primary site for the dyskinetic muscle contraction, which is the pathophysiologic cause of dysmenorrhea.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(7) Referring to the drawings in greater detail, FIG. 1 is a female pelvic anatomy diagram illustrating a tampon T which has been inserted into a vaginal cavity 10. The tampon is expanded, and properly positioned adjacent the opening to uterus 12. A partially disintegrated cannabinoid delivery device 14 is shown properly inserted and positioned by the expanded tampon. This view illustrates the desired functioning of the device of the present general inventive concept, after use, as now will be described.

(8) Referring to FIG. 2, a tampon and cannabinoid delivery device in accordance with the present general inventive concept is generally designated by the numeral 16. The device includes a generally cylindrical inserter means 18. The inserter means as shown is in the form of a round sheathing tube defining a cartridge for slidably receiving a tampon T for ejection through one end portion 20 of the cartridge.

(9) Ejecting means 22, in the form of a generally hollow cylindrical plunger member, is slidably received within a tapered end 24 of cartridge 18 opposite end 20 of the cartridge. The ejecting plunger 22 engages the inner proximal end of tampon T for ejecting the tampon from end 20 of cartridge 18. The tapered end 24 of cartridge 18 provides a finger grasping portion to facilitate ejection of the tampon by means of an individual's thumb engaging the outer end 26 of plunger member 22.

(10) A generally bullet-shaped spheroid 14A molded of cannabinoid-infused disintegrable carrier material is at least partially embedded within and movably held by tampon T for delivery into vaginal cavity 10 (FIG. 1) by ejection from cartridge 18 after the cartridge is inserted into the vaginal cavity.

(11) In the form of the inventive concept shown in FIG. 2, carrier spheroid 14A is embedded and held within tampon T generally centrally thereof adjacent end 20 of cartridge 18. Normally, the density of the tampon would be sufficient for retaining and holding the carrier spheroid for proper insertion completely within the vaginal cavity as described in relation to FIG. 1. However, in some particular circumstances, or with certain tampon materials, it may be desirable to utilize a biocompatible adhering substance between the spheroid and tampon to facilitate proper and precise positioning of the carrier spheroid within the vaginal cavity.

(12) Referring to FIG. 3, a beneficial feature of the present general inventive concept is the provision of features on cartridge 18 for facilitating pre-lubrication of tampon T prior to insertion into the vaginal cavity. More particularly, cartridge 18 is provided with aperture means in the form of a plurality of slotted fenestrations 28 through the sides thereof for pre-lubricating the tampon. The slotted fenestrations preferably extend lengthwise of the cartridge along a substantial length of the tampon to insure complete lubrication of the tampon. The tampon itself is fabricated of a compressed body of suitable soft, porous and absorbent material which expands appropriately within the vaginal cavity as shown in FIG. 1. This pre-lubrication feature of the present general inventive concept is also enhanced by the fact that the cannabinoid carrier spheroid is at least partially embedded within the tampon itself. In this manner, the embedded portion of the carrier spheroid is activated just as rapidly as the protruding portion which is activated primarily by body heat. The combination of the pre-lubricated tampon and body heat, promotes a rapid break-down of the carrier material for the cannabinoid-infused in the carrier material. Thus, it can be seen that the embedding of the carrier spheroid within the tampon provides a dual function of insuring proper positioning of the carrier spheroid within the vaginal cavity as well as combining with the pre-lubrication feature of the present general inventive concept to insure rapid and uniform dissolving of the carrier spheroid itself.

(13) Referring to FIG. 4, it can be seen that the outer end of cartridge 18 closes over the peripheral edge of the tampon and is slotted, as at 30, to define generally triangular wedge-shaped segments 32 which surround and engage the portions of carrier spheroid 14A which protrude from the tampon. These triangular wedge-shaped segments also facilitate holding the carrier spheroid in proper position centrally embedded in the tampon.

(14) Referring to FIG. 5, a modified form of cannabinoid-infused carrier, generally designated 14B, is shown. Except for the elimination of the closed end 20 of cartridge 18, the tampon and associated components are identical to the device shown in FIGS. 2 and 3 and like numerals have been applied.

(15) Carrier spheroid 14B shown in FIG. 5 is generally mushroom shaped with a stem portion 34 embedded and held within tampon T, similarly to the description of carrier spheroid 14A, above. Carrier spheroid 14B includes an enlarged, rounded head portion 36 which protrudes radially outwardly and overlies both the end of tampon T and the open end of cartridge 18. Just as with the rounded end 20 and round carrier spheroid 14A in FIG. 2, the rounded head portion 36 of carrier spheroid 14B prevents any damage to the lining of the vaginal cavity and the uterus during insertion of the tampon and delivery device thereinto.

(16) With both forms shown in FIGS. 2 and 5, a removal string 38 is secured at one end to the inner proximal end of tampon T and extends completely through the opposite end of the generally hollow ejecting plunger member 22. After the tampon and carrier spheroid are properly inserted into the vaginal cavity, cartridge 28 and plunger member 22 may be removed and discarded, leaving removal string 38 for subsequently removing the tampon after a prescribed period of time.

(17) The above described embodiments are set forth by way of example and are not for the purpose of limiting the scope of the present general inventive concept. It will be readily apparent that obvious modifications, derivations and variations can be made to the embodiments without departing from the scope of the present general inventive concept. Accordingly, the claims appended hereto should be read in their full scope including any such modifications, derivations and variations.
