An apparatus for insertion into a mouth cavity of a person who is to receive oral administration of healthcare products dispensed from said apparatus, the mouth cavity having cheek sidewalls and a rear throat wall, the apparatus comprising: a nipple base comprising a proximal face, a distal face, and a passage extending through the nipple base and centrally located thereon, said base having a central axis extending perpendicular to said proximal face, said central axis projecting towards and in a perpendicular direction relative to the rear throat wall when the apparatus is inserted into the user's mouth; a nipple having a contoured wall that defines a cavity extending between a distal and a proximal end thereof, said nipple extending from the proximal face, and having a proximal tip located on the central axis, the contoured nipple wall having an inner side and an outer side and forming a bulbous portion at said proximal nipple end, said bulbous portion radially centered about said central axis; a proximal tube portion of a receiving tube having a longitudinal axis that is parallel to and offset from said central axis, the nipple having a nipple aperture located along said bulbous portion such that said aperture is offset from said proximal tip and longitudinal axis by an angle between 1° and 90° so that dispensed healthcare products only contact a cheek sidewall, the said proximal tube portion centered about said longitudinal axis and extending through the nipple and at least a portion of the passage, the receiving tube comprising a proximal portion that terminates at and is in communication with the nipple aperture and a distal portion, the proximal portion having a first inner diameter and the distal portion having a second inner diameter that is larger than said first diameter, wherein the distal portion is sized to securely couple to an occlusion mechanism (170,182) or a healthcare accessory; wherein the nipple, the nipple base, and the receiving tube are together integrally molded to form a unitary monolithic body; and optionally, an occlusion mechanism (170, 182) extending from the nipple base for selectively occluding the receiving tube; and optionally, a healthcare accessory configured to be securely coupled to the distal portion of the receiving tube, the healthcare accessory (200, 300) containing a predetermined volume of a predetermined fluid, wherein the healthcare accessory comprises a reservoir wall defining a reservoir with fluid and an aperture. a nipple base comprising a proximal face, a distal face, and a passage extending through the nipple base and centrally located thereon, said base having a central axis extending perpendicular to said proximal face, said central axis projecting towards and in a perpendicular direction relative to the rear throat wall when the apparatus is inserted into the user's mouth;
