9 Claims. (Cl. iBS- 232) This invention relates in general to a means for administering medicine to a body canal, and in particular to a tampon which readily permits internal administration of medicine and absorbs body fluids while preventing loss of the administered medicines. The tampon of this invention is highly effective in administering and retaining pain relieving medicaments in the vaginal canal during periods of menstruation.
`The female body normally undergoescyclic periods of menstruation which is sometimes accompanied by severe internal pain. Medicaments have been designed to aleviate the pain. -Howeven simple and effective administration and retention of these medicaments in the vaginal canal is a troublesome problem. Often the administered medicine is either washed out of the body by secreted iluids or absorbed and retained by Iabsorption devicesused in conjunction with the medicinal administration.
In many cases a tampon is employed having a drilled passageway extending throughout the length ofthe device. Medicaments are administered through .the passageway into the body cavity and the tampon acts as a liquid absorption means. It has been found that a substantial percentage of the medicaments administered in this manner reenter the passageway and are absorbed by the tampon. Costly medicaments are often lost and improper dosages frequently result.
Accordingly it is an object of this invention to provide a lsimple and eiiicient device for administering medicine to a body canal. The device is simple to use and readily permits passage of medication through a passageway, yet minimizes return of the medication through the same passageway. i
It is a further object of this invention to provide a device 4in accordance with the preceding object which is light and compact previous to usage. Nonetheless, the device is capable of absorbing substantial amounts of secreted body uids.
It is another object lof this invention to provide a device in accordance with the preceding object which is inexpent sive to manufacture, employing basically conventional manufacturing procedures.
It is still a further object of this invention to provide a device in accordance with the preceding objects having an interengaged dispensing means. The dispensing means facilitates the handling and applications of the device. ln addition, the dispensing means permits application of uniform prescribed doses of medication. i
In accordance with the invention, the tampon has an elongated core composed of a fluid absorbent material capable of automatically expanding upon absorption of a liquid. An elongated passageway extends throughout the core and opens at either end of the core. The passageway comprises a first portion formed either byremoving the material from the elongated core or by molding the core around a mandrel, and a second portion formed by parting or deliecting a portion of the core. The second portion of the passageway is blocked when the core absorbs fluid and the parted or deflected materials expand and return to the original position. in a preferred form, the core is composed of a fibrous material having properties of elastic memory. The passageway is axially located within the core and adapted to receive a tubular portion of a dispensing means.
Numerous other features, objects and advantages of the present invention will become apparent from `the following specification when read in connection with the accompanying drawings, in which:
FlG. 1 is a cross sectional view of a preferred embodiment of this invention;
FIG. 2 is atop plan view thereof;
FG. 3 is a fragmentary side view of a forming tool useful in constructing the tampons of this invention;
FIG. 4 is a side view of an assembled device of this invention showing portions in cross section;
FIG. `5 is a cross sectional view through the center of an expanded form of the device as shown in FIG. l;
FIG. 6 is a side cross sectional view of a modilied form of this invention; and,
HG. 7 is a side cross sectional view of still another modiiication of this invention.
According to the invention, the tampon indicated generally at 2d, has a generally cylindrical core liti, formed of an absorbent material. A head il of the core l0 is preferably tapered for `ease of insertion of the tampon.
The core it) is composed of conventional compressible and expansive material known to the art. Absorbent cotton is a preferred material due to its highly absorbent nature and ease of shaping and forming. Cotton is also preferred since it is relatively inexpensive, light in weight and generally non-irritating. The core lil may be made into any desired shape having necessary dimensions suited to the particular body cavity in which the tampon is to be employed. For vaginal application a length of approximately 1% inches and `a diameter of 1b. inch is preferred.
A passageway l1 extends axially of the cylindrical core it) from the lower portion 15 through the upper portion or tapered end 1li. The lower portion of the passageway i13 comprises a cylindrical bore i7, as best shown in FIG. l, below line A-A. The cylindrical bore i7 is formed by removing material from a compressed cylindrical core il@ or by molding the core around a mandrel as will be more fully described hereinafter. An upper portion of the passageway 13 comprises a deflected or spread apart passageway having an `opening passageway 12, as best shown in FlG. l, above line A-A. The passageway portions lS and l2 are preferably formed by deliecting or spreading apart fibers of a compressed cotton core 10. Although an actual opening is provided, it should be understood that the material spread apart or deected has an elastic memory and tends to return to its original position when the core l@ is impregnated with a liquid as will be more fully described hereinafter.
Preferably a cotton netting 21 extends entirely about the cylindrical core lil. Attached to the lower end of the netting 2l and the core it) is a conventional pull string i6. The netting 2l acts as a support structure to prevent disintegration of the tampon when it is exposed to a liquid.
As tbest seen in FIG. 4, passageway i3 snugly and slidably receives a tubular portion il of a medicament dispense-r` designated generally at dit. Preferably, a bulb shape enlarged portion d2 is provided adjoining tubular portion di. A medicine containing resilient receptacle i3 forms a lower end of the dispenser dit. The upper portion `of the tubular portion il has a plug or stopper id force fit to seal the endtof the tubular member di. While many types of medicament dispensing devices may be employed with thetcylindrical core lli, the above described dispenser 4@ is preferred. This dispenser provides a means for accurately measuring and administering a preselected dosage of medicine to a body canal.
Normally the dispenser is lled completely to the stop id with the desired medicament. lhe medicament may comprise any one of a number of therapeutic formulations such as pain relieving jellies, antiseptic compounds,
Y testing dyes, etc.
Patented Sept. 3, i963 Preferably the dispenser `fill' is composed of a plastic material such as polyethylene having sufficient rigidity to allow manipulation of fthe tampon into the desired location. Polyethylene plastics are particularly desirable since they are relatively inexpensive and may be easily formed. Alternatively plastics such as polystyrene and vinyl plastics may be employed if desired.
The bulb shaped enlargement 4Z has a dual function in Ithat it acts as `an enlarged strengthening member for the tubularrportion of the dispenser 4G' and in addition selectively determines the length of travel of the tube il into the passageway 1'3. In effect enlargement l2` provides a stop for the dispenser 4th. Preferably the upper edge of the tubular portion 41 is located adjacent openp ing passageway 12 and does not extend completely to the outer surface of the tapered head 1,1.
The manufacture of tampons according to this invention is basically similar to conventional manufacturing procedures used for tampons such as Meds tampons produced by Kimberly Clark. Absorbent material such as cotton is highly compressed to form a solid cylindrical core of the type described above. Any means such as a drill or hollow core tubular punch is then employed to remove material below the line A-A stanting from end 15 of the core 19.
In an alternate procedure the core 10 is molded and compressed about a central mandrel which forms passageways 17 below line A-A. Since no cotton material ever occupies passageway .17, throughout the specification and claims, this molded passageway is considered tov be equivalent to one formed by removing material as above described. The upper portion of the passageway comprises a basic feature of lthis invention and must be formed by resiliently deforming or spreading apart the material of the upper end of the cylindrical core llt). Preferablya forming tool of the type shown in FIG. 3 is employed. After ythe portion 17 is bored, the forming tool 50` is inserted in the bore and compressed against the upper portion of the core 10 thereby forming opening 12 and portion 1S. In the embodiment shown in FIG. l, the forming Itool Si)` has a piercing point 33 which actually passes 'through and beyond the tapered head 11. I-t is sometimes desirable to place a mold on the outside of and in facing relation to the tapered head 1.1 when employing the tool 50. This expedient positively prevents distortion of the tapered head 11, during the hole forming operation. Y
It is -a key feature of this invention that the portion of the passageway above Iline A-A, has had fibers deflected or spread apant rather than removed as is the case with portion 17. In fact the fibers in a neck portion surrounding the passageway above line AA are in fact moreA highly compressed than are the fibers of the remaining core 10'. Thus, upon wetting of the tampon 20, the compressed fibers of the cot-ton material tend to expand and assume their original shapes. This feature enables the opening i12 and passageway portion 18 to be closed. In effect, Athe cotton fibers have been elastically deformed and compressed in a neck section surrounding opening 112 and passageway pontion 13, in such a manner that closing of the passageway occurs upon expansion of the material. An example of the expansion of the fibers and closing of opening 12 is shown in FIG. 5. Eectivelythe opening is closed and the tampon swelled to several times its original dimensions.
The portion of the passageway 13 fbe'low line A-A alsol swells upon impregnation. However, since material has been removed frequently, the pontion 17 contracts, buit does not close completely thereby providing a passageway along which fluids may flow and/or be internally absorbed by the core 10. v
After manufacture of the cylindrical core 10', the medicament dispenser may be fitted loosely along the passageway :13 as shown in FIG. 4. Preferably the tip of tubular member 41 does not extend entirely through core 10. Contact of the tapered head 11 with body fluids tends to automatically close fthe opening 12 and prevents return of the dispensed medicants along the Vpassageway 13. Y
An alternate embodiment of the invention is shown in FlG. 6 Iwherein a cylindrical core 69' has a Ibored out passageway I61l connecting a spreadl apart or resiliently compressed opening passageway 62. Still another modification is shown in FIG. 7, wherein a cylindrical core '70 has a bored out cylindrical portion 71 with a spread apart or resiliently compressed cone shaped opening 72 coaxially adjoining the lopening 71. In all modiiications it is important that the end openings 412, 62` and 72 are not formed by cutting out or removing material of the core portion.
The particular conguration and dimensions of the yopening passageway may vary consistently with the overall size of the tampon and the relative expansion and return of materials to close the opening. Preferably'when cotton materials are employed having long elastic fibers of a conventional nature, the lspread apart passageways extend above line A-A for at least 1/32 inch. Prefer- :ably the `diameter of the passageways are made las small as possible consistent with ease of dispensing fluids from the dispenser employed with the tampon. In the specific embodiments illustrated in FIGS. 1-5, passageway17 has a diameter of 5/32 inch, while passageway 12 is for-med with a diameter of 1/a inch. The diameter of passageway 17 is exaggerated in FIG. l in o-rder t-o simplify understanding -of the invention. ln some embodiments of the invention portions 12, 17 land 1S have equal diameters.. As shown in the embodiment of FIGS. 6 .and 7, the
outer configuration and dimensions of the core -10 may vary considerably depending upon ythe body opening in which the tampon is to be inserted.
The specific embodiments of this invention described `above are by way of example only. Those skilled in the art may now make numerous variations. i Therefore, while there has been described what are :at present considered to be preferred embodiments of this invention, it will be yobvious to those skilled in the `art that various changes and modifications may be made therein without departing from the spirit and scope `of the invention, and it is therefore aimed in the appended claims to cover all such changes and modifications as are inherent in the true spirit and scope of this invention.
