Description
This invention relates to an orthodontic cradleboard for infants
and more particularly to a cradleboard for infants wherein the
infant is properly positioned therein to enable optimum development
of the child's body.
BACKGROUND AND OBJECTS
The prior art is replete with various devices for supporting infant
children such as baby holders, baby carriers, cribs and the like.
Most of these devices are used to support an infant in a variety of
positions particularly while the infant is asleep, but likewise
when sitting, being fed, etc.
Research has shown that a child's sleeping habits at an early age
mold the facial form of the child, and when it is molded in such a
fashion as to constrict the dental arches, the constriction is a
cause of the retardation of normal and adequate growth. Since the
size of the teeth is genetically predetermined, if the teeth erupt
into an area where bone growth has been mechanically inhibited, a
crowded condition will result and orthodontic corrective action
will be necessary. Additionally, many faulty sleeping habits that
result in crooked teeth, also result in other body deformations.
Unnecessary curves in the spine and shoulders are caused by faulty
sleeping habits. Proper habits established during the first year of
life will give the body the greatest potential for continuing
proper development.
It has been shown that sleeping on the stomach tends to put
pressure on the lower jaw, thus hindering its forward growth. This
posture helps to develop the Class II malocclusion. Also, it keeps
pressure off the back of the head which is the first area of the
head to calcify, while the maxillofacial complex (nose, cheeks and
boney ridges investing the teeth) is the last place to calcify.
Thus, sleeping on the stomach permits the overgrowth of the back of
the head which causes a negative pressure in the temperomandibular
joint, thus increasing the potential for underdevelopment of the
lower jaw.
With the child lying on its back, there can be no pressure on the
bones of the face to distort development there. The back of the
head is thus prevented from becoming large and bulbous appearing as
so many 2 year olds demonstrate.
Sleeping on the stomach is sometimes accompanied by the hands or
arms under the pillow against the face, or directly against the
face. This frequently results in lack of proper development of the
malar processes, with resultant crowding of the teeth on that side
into a cross bite. There can also be a nasal septum deviation
resulting in a crooked nose, one nostril being smaller than the
other, and possible breathing difficulties associated with the
septum.
The overall posture is hunched over for stomach sleepers, and the
shoulder blades tend to protrude.
American Indians frequently used cradleboards for their children,
however, their cradleboards were flat, and the children's legs were
held flat against it. This caused an increased incidence in
congenital hip dysplasia. It occurred in about 6 percent of the
populace, whereas only about 3 percent would be considered normal.
This also caused an upward arching in the spine and the low back
area.
Therefore, a primary object of this invention is to provide a
cradleboard for infants for encouraging proper body
development.
Another object of this invention is to provide a cradleboard for
infants which assist in promoting good dental development.
Another object of this invention is to provide a cradleboard which
encourages proper sleeping habits for infants.
Still another object of this invention is to provide a cradleboard
for infants wherein proper spinal development is promoted.
Still a further object of this invention is to provide a
cradleboard of simple, lightweight construction.
Yet another object of this invention is to provide a cradleboard
having a padded body-supporting surface.
Yet a further object of this invention is to provide a cradleboard
which overcomes the difficulties of prior art cradleboards.
These and other objects and advantages of this invention will
become apparent when considered in light of the following
description and claims when taken together with the drawings in
which:
FIG. 1 is an exploded perspective view of the cradleboard of this
invention; and
FIG. 2 is a longitudinal section along lines 2--2 of FIG. 1 and
viewed in the direction of the arrows.
DESCRIPTION OF THE INVENTION
This invention provides a support for infants which encourages
proper development of the body according to the genetic pattern,
and prevents extraneous pressures from malforming the body. Using
the cradleboard of the invention, children will tend to develop
flat shoulder blades and good posture. This is due to the spinal
position on the cradleboard whereby it is held straight. The legs
are elevated to help straighten the back, and the legs are held
apart at approximately a 30.degree. angle. This holds the head of
the femur into the acetabulum of the hip girdle at the proper angle
to assure the proper formation of the hips. This also keeps weight
off the hip girdle thus helping to prevent hip dysplasia.
Referring now to FIG. 1 of the drawings, the cradleboard generally
designated 10 is seen to have a base portion 12, sides 14, a foot
end 16 and a head end 18.
The cradleboard includes a body-supporting surface 20, and
immediately adjacent thereto, is a head-supporting surface 22. As
best seen in FIG. 2, the head-supporting surface 22 is slightly
lower than the body-supporting surface 20 to accommodate the head
in a natural position.
Extending from the body surface 20 are a pair of leg-supporting
surfaces 24 which are elevated above the body-supporting surface
20. Additionally, the leg-supporting surfaces 24 are separated by a
raised portion 26 of the cradleboard. The raised portion 26 serves
to separate the leg-supporting surfaces 24 at an angle of
approximately from about 25.degree. to about 35.degree., and
preferably at an angle of about 30.degree..
Head, body and leg-supporting surfaces 20, 22 and 24 respectively
are seen to include a plurality of fastener members 28 such as
snaps, Velcro fasteners or other suitable fastening devices.
Immediately adjacent the body-supporting surface 20 are a pair of
longitudinally extending slots 30 which receive a strap or belt 32.
A pad 34 is shown and includes fasteners 36 which correspond to
fasteners 28. Fasteners 28 and 36 cooperate to secure pad 30 in
position if desired.
Surfaces 20, 22 and 24 are all contoured slightly to receive the
appropriate portions of the human body in a comfortable manner. The
pad 34 is such that it can conform to the surfaces.
Around the periphery of each of the surfaces 20, 22 and 24 is an
upstanding rim 38 which assists in positioning an infant on the
cradleboard and restricts lateral shift of the body on the
cradleboard.
The base portion 12 is seen to include outwardly turned flanges
which suitably support the cradleboard 10.
In the preferred embodiment, the cradleboard 10 is molded from a
high impact strength plastic such as the various acrylics,
polystyrenes or the like. This provides a light weight yet rigid
structure.
The strap 32 serves to secure an infant in the cradleboard 10, and
serves as a swaddling band. Psychiatrists have demonstrated that a
swaddled baby is generally a happier baby, and with arms confined
alongside of the body by means of the strap 32, thumb sucking and
scratching of the face and the eyes by fingernails are prevented.
The strap also stimulates isometric muscle exercise which in some
ways is superior to isotonic exercise.
The upstanding rim 38 serves to protect the child if the
cradleboard 10 is dropped, and suitable attachments could be made
to the cradleboard for carrying the same by hand, or for securing
it in an automobile.
Further, the structure could be made from more than one piece to
permit lengthening of the cradleboard as the child grows.
Additionally, the hollow area under the cradleboard could be
adapted for storage of diapers, bottles and other infant
necessities, and a cover 40 may be provided which can be snaped or
otherwise secured to the base 12.
While this invention has been described, it will be understood that
it is capable of further modification, and this application is
intended to cover any variations, uses and/or adaptations of the
invention following in general, the principle of the invention and
including such departures from the present disclosure as come
within known or customary practice in the art to which the
invention pertains, and as may be applied to the essential features
hereinbefore set forth, as fall within the scope of the invention
or the limits of the appended claims.
