DETAILED DESCRIPTION OF THE BEST MODES AND PREFERRED EMBODIMENTS OF THE INVENTION
FIG. 1 shows a perspective view illustrating diaper changing system 100 according to a preferred embodiment of the present invention.
Preferably, diaper changing system 100 comprises diaper changing mat 101, as shown. Preferably, diaper changing mat 101 comprises the following preferred components: mat 110, shield 120, connector 130, and accessor 140, as shown. Upon reading the teachings of this specification, those with ordinary skill in the art will now understand that, under appropriate circumstances, considering such issues as advances in technology, user preference, etc., other diaper changing system components, such as safety straps, attachment straps, accessory storage pockets, storage containers, toys, pillows, handles, removable absorbent covers, etc., may suffice. It is highly preferred that diaper changing system 100 be disposable as this provides user convenience with respect to discarding soiled diaper changing system 100. In the event that the diaper changing system 100 is not soiled, a user may preferably reuse diaper changing system 100 accordingly.
Preferably, mat 110 is structured and arranged to lie under at least the legs, the buttocks, and the back of an infant when the infant is laid down on his or her back for a diaper change, as shown. More preferably, mat 110 is structured and arranged to lie under the entire length and width of the infant, as shown. For the purposes of the present patent application, an infant is defined as a human infant typically between about zero and about thirty-six months of age and typically ranging from about eighteen inches to about forty inches in total length.
Preferably, an infant is placed on mat 110 and, subsequently, shield 120 is laid over the infant during-diaper changing procedures (removing a used diaper; cleaning the infant's bottom; applying any powders, ointments, etc.; applying a fresh diaper; etc.), as shown. Preferably, shield 120 is preferably drapeable meaning that, in use, it drapes intended portions of an infant, or is infant-drapeable, as shown (at least embodying herein wherein such at least one second material layer comprises drapeable portions structured and arranged to drape at least over lap portions of such at least one infant). Preferably, shield 120 is flexible, infant-drapeable, and absorbent. Preferably, shield 120 is structured and arranged to lay over no more than about three-fourths the length of a typical infant, as shown, in order to absorb wastes generated by the infant. Such wastes are typically urine, but may also comprise other infant-generated wastes such as feces, other infant-generated body fluids, etc. More preferably, shield 120 is structured and arranged to lie over the lap of the infant, as shown, in order to absorb wastes generated by the infant. For the purposes of the present patent application, the lap is defined as being any portion of the infant substantially between the belly button region and the knee region of the infant on the front side of an infant.
It is common for infants to urinate during diaper-changing when a used diaper is removed. This urine may stream for great distances through the air necessitating clean-up of any urine contacting objects like a parent, the infant, surrounding furniture, personal belongings, etc. Preferably, shield 120 functions to prevent exposure to such urine streams and to prevent such urine streams from leaving the immediate environment of the infant. Shield 120 may also functions to at least partially absorb such urine streams so that the infant is not soaked.
Shield 120 is connected to mat 110 by way of preferred connector 130, as shown. Preferably, connector 130 is structured and arranged to hingedly connect shield 120 to mat 110 along the same axis as the length the infant, as shown. More preferably, connector 130 is structured and arranged to connect shield 120 to mat 110 adjacent the lap of the infant (i.e., adjacent the infant's hips), as shown. Preferably, connector 130 connects shield 120 to the side edges 111 of mat 110, as shown. Preferably, mat 110 and shield 120 are sewn together. More preferably, mat 110 and shield 120 are a single piece of fabric where connector 130 (at least embodying herein at least one connector structured and arranged to connect such at least one first material layer to such at least one second material layer) comprises a living hinge, or fold, defining the connection between mat 110 and shield 120, as shown. Preferably, mat 110 (at least embodying herein at least one first material layer structured and arranged to lay at least under thigh portions, buttock portions, and lower-back portions of such at least one infant) and shield 120 (at least embodying herein at least one shield structured and arranged to prevent urine exposure from urine generated by such at least one infant) are connected to each other so that shield 120 does not get lost and so that the infant cannot easily displace or remove shield 120 from over his or her lap when the system is in use. Upon reading the teachings of this specification, those with ordinary skill in the art will now understand that, under appropriate circumstances, considering such issues as advances in technology, user preference, etc., other methods of connecting the mat to the shield, such as the shield being a rigid material attached to the mat with a metal or plastic hinge, etc., may suffice.
FIG. 1A shows a partial close-up view illustrating a preferred material property of the interface between mat 110 and shield 120 of diaper changing system 100 according to a preferred embodiment of the present invention. Preferably, connector 130 comprises elastic material 131 (at least embodying herein at least one expander permitting raising and lowering of such at least one shield relative to such at least one mat). In use, preferred elastic material 131 stretches so that, when a diaper changer lifts an infant's bottom, the bottom of the mat will remain substantially flat against the below-supporting surface. Further, elastic material 131 may also preferably accommodate larger-sized infants. For a larger-sized infant, elastic material 131 is beneficial in that it permits shield 120 to better drape over such larger-sized infant.
FIG. 1B shows a partial close-up view illustrating a preferred slit arrangement for connector 130 of diaper changing system 100 according to another preferred embodiment of the present invention. Connector 130 alternately preferably comprises slit 132 (alternately preferred to expander elastic material 131), as shown. In use, slit 132 provides a partial opening of connector 130 so that, when a diaper changer lifts an infant's bottom, the bottom of the mat will remain substantially flat against the below-supporting surface. Also, slit 132 (at least embodying herein wherein such at least one expander comprises at least one slit) may preferably be used to accommodate larger-sized infants.
As stated above, diaper changing system 100 comprises accessor 140, as shown. Accessor 140 is preferably defined by mat 110 and shield 120 as shown. Preferably, accessor 140 permits access to an infant from the diaper-end (feet-end, bottom end, etc.) of an infant during diaper-changing, as shown. In other words, accessor 140 provides a pathway structured and arranged to permit access by a diaper-changer to bottom portions of an infant during diaper-changing. Preferably, accessor 140 (at least embodying herein wherein such at least one mat and such at least one shield comprise at least one pathway structured and arranged to permit access by such at least one diaper-changer to bottom portions of such at least one infant during diaper-changing) is a function of the shape of shield 120 overlying the infant and connected to mat 110 only along the sides of the infant with no obstructions between the infant's legs, as shown. Preferably, a diaper-changer may reach under shield 120 to change the infant-worn diaper with shield 120 in place to block infant-generated urine.
