Pacifier with thin-film reservoir and method for use thereof
View Patent ↗The invention relates to a pacifier and nipple member for delivery of active ingredients into the oral cavity of an infant or patient. The pacifier includes a porous nipple member and a base member adapted to remain outside the oral cavity of the infant. The porous nipple member includes at least one reservoir or chamber therein for receiving a thin-film containing an active ingredient. The base member may be removably attached to the neck of the nipple member, or the nipple and base members may form a single unit. Reusable and disposable forms are disclosed.
1. A pacifier for delivering an active ingredient to an infant or patient comprising:
a base member comprising a shield;
a porous nipple member attached to one side of said base member, said nipple member having a wall defining at least one chamber, an inner surface of said wall being in contiguous contact with said chamber, said chamber containing a dissolvable thin-film comprising an active ingredient; and
said thin-film being held-in-place by a retaining mechanism for said dissolvable thin-film, said retaining mechanism having a first retaining finger outwardly projecting from said inner surface and having an unattached end, wherein said first retaining finger continuously holds said dissolvable thin-film against said inner surface.
2. The pacifier of claim 1 , further comprising at least one flap located on the external surface of the nipple to permit positioning of the film in said chamber.
3. The pacifier according to claim 1 , wherein said porous nipple member further comprises a neck and said shield comprises a concave side and a convex side, wherein said shield has an attachment member disposed on the concave side of said shield for engaging said nipple member.
4. The pacifier according to claim 3 , wherein said neck and said attachment member comprise threaded-mating portions.
5. The pacifier according to claim 3 , wherein said neck and said attachment member comprise a snap-fit.
6. The pacifier according to claim 3 , wherein said neck and said attachment member comprise a bayonet-lock fit.
7. The pacifier according to claim 3 , wherein said base member further comprises a handle attached to the convex side of said shield.
8. The pacifier according to claim 3 , further comprising a solid plug shaped to fit within said neck of said nipple member.
9. The pacifier according to claim 1 , wherein said thin-film has a thickness of about 0.1 mils to about 10 mils.
10. The pacifier according to claim 1 , wherein said active ingredient is selected from the group consisting of: pharmaceutical agents; cosmetic agents; drugs; medicaments; antidotes; vaccines; antigens or allergens; mouthwash components; flavors; fragrances; enzymes; preservatives; sweetening agents; colorants; spices; vitamins; and combinations thereof.
11. The pacifier according to claim 1 , wherein said active ingredient is selected from the group consisting of: aspirin; benzocaine; lidocaine; diphenhydramine; simethicone; vitamins; cold and cough medications; and combinations thereof.
12. The pacifier according to claim 1 , wherein said active ingredient comprises fentanyl.
13. The pacifier according to claim 1 , wherein said thin-film has a curled shape.
14. The pacifier of claim 1 , wherein there is further included a hermetically sealed package containing said pacifier.
15. The pacifier of claim 1 , wherein said retaining mechanism further comprises a second retaining finger outwardly projecting from said inner wall and having an unattached end, wherein said unattached ends of said first retaining finger and said second retaining finger are spaced apart so that said unattached end of said first retaining finger does not come into contact with said unattached end of said second retaining finger.
16. A method for delivering an active ingredient to an infant or patient comprising the steps of:
providing a thin-film comprising an active ingredient;
providing a porous nipple member of a pacifier comprising a wall defining at least one chamber, an inner surface of said wall being in contiguous contact with said chamber and having at least one retaining mechanism, said retaining mechanism having a first retaining finger projecting outwardly from said inner surface and having at least one unattached end;
inserting the thin-film into the at least one chamber of the porous nipple member, wherein said first retaining finger is configured to continuously hold said dissolvable thin-film against said inner surface; and
orally administering the pacifier to an infant or patient thereby allowing the thin-film to dissolve and release the active ingredient into the oral cavity.
17. The method according to claim 16 , wherein the method further includes the step of wetting the chamber containing the thin-film to facilitate dissolution of the film.
18. The method according to claim 17 , wherein the porous nipple member further contains a reservoir or chamber which houses a liquid.
19. The method according to claim 16 , further comprising the step of attaching the porous nipple member to a base member, wherein the nipple member comprises a neck that engages an attachment member disposed on the base member.
