Description

BACKGROUND OF THE INVENTION

The present invention generally relates to a system for preventing positional plagiocephaly, and more particularly to a system for preventing positional plagiocephaly in infants while they sleep. The present invention also relates to a method for the prevention of positional plagiocephaly.

Sudden Infant Death Syndrome (SIDS) is a devastating problem with no known cause. The American Academy of Pediatrics recommended years ago that babies should sleep on their backs on the assumption that part of the SIDS problem might be related to infants suffocating face down in their cribs. The Back to Sleep program began nationwide, and the results have been analyzed. A clear statistical reduction in SIDS deaths occurred after the program was installed.

Some time after the program started, doctors began seeing an increasing number of babies with distorted heads. A number were treated with extensive surgery. Later, it became clear that the distortion, mostly flatness of the back and side of the head, was a direct result of the sleeping position. The weight of the brain on the thin skull bone changes the growth rate, and a progressive deformity occurs for the first four to six months of life. Once infants have a flat spot on their skull, the flatness becomes exacerbated due to the inability of the infants to move their heads once lying on the flat spot due to the general weakness all infants exhibit in their necks.

Historically, several cultures experienced similar positional distortions. The Plains American Indians, by strapping infants to a cradle board, caused uniform flatness of the back of the head. The present condition of positional plagiocephaly causes similar skull and neck distortions.

Therapeutic programs to correct the distortion developed, including physical therapy and helmet molding or pressure relief programs. These programs assist some in the correction of the several characteristic shape presentations.

To date, only presumptive circumstances can be used as predictors as to which babies will develop the deformity (large males, twins, and preemies).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As mentioned above and explained in more detail below, the present invention relates to a system and a method of preventing positional plagiocephaly in infants. In general, a system 2 includes an infant receiving member 10, which includes an infant supporting surface 12, a first portion 14, and a second portion 16. Further, an inclined member 30 is typically at least partially positioned under either the first portion 14 or the second portion 16 of the infant receiving member 10 such that either the first portion 14 or the second portion 16 is inclined.

As shown in FIG. 1, the infant receiving member 10 is typically any generally planar article or material capable of supporting an infant. In one embodiment, infant receiving member 10 is a generally rectangular mattress capable of comfortably supporting an infant. The term “mattress” is not intended to be defined as including or being limited to a specific material or materials. Instead, the term “mattress” shall include any material or combination thereof, which is capable of either independently or in combination with other surfaces, supporting an infant thereon. The material of which infant receiving member 10 is typically fabricated from is not critical to the inventive concept and any material or shape thereof may be used. However, the material is typically at least partially deformable such that it forms an inclined portion when inclined member 30 is placed at least partially under it. In one embodiment, a generally rectangular foam material is used. Further, the infant receiving member 10 may be covered (not shown) with a covering, such as a sheet or other covering material. As will be discussed in greater detail later, the covering material may include pockets for receiving inclined member 30. Infant receiving member 10 also includes an infant supporting surface 12 generally centrally disposed thereon. Infant supporting surface 12 generally includes a substantially central area that typically includes a harness 40 (discussed below). Of course, infant supporting surface 12 along with harness 40 may be disposed anywhere on or within infant receiving member 10. Infant receiving member 10 also typically has a first portion 14 and a second portion 16. The first and second portions 14 and 16, respectively, divide the infant receiving member 10 into two portions, typically two substantially symmetrical portions. Typically, the first and second portions are drawn about a longitudinal axis of infant receiving member 10 as indicated in FIG. 1 as axis A.

Inclined member 30 is typically disposed adjacent back surface 22 of infant receiving member 10 to incline, tilt, or otherwise “prop up” either first or second portion 14 or 16, as illustrated by FIG. 2. Inclined member 30 may be fabricated from various materials and in various geometrical shapes. However, inclined member 30 is typically a generally V-shaped member, including a first substantially pointed end 32 and a second substantially truncated end 34. Most typically, the inclined member 30 is made from a foam material, typically a urethane type foam, but the inclined wedge member can be made from other materials, such as metal, wood, or plastic. Inclined member 30 may also be covered with any suitable covering.

When inclined member 30 is disposed at least substantially adjacent back surface 22, as illustrated in FIG. 2, the inclined member 30 may optionally be affixed thereto. The inclined member 30 may be affixed using any known method, but typically is affixed using a hook and loop style attachment system, as illustrated in FIG. 3, wherein back surface 22 of infant receiving member 10 may contain one of the hook or loop parts of the hook and loop attachment system, and a first or a second surface 36 or 37 of inclined member 30 may contain the corresponding loop or hook parts of the hook and loop style attachment system. The above-mentioned hook and loop style fastening or attaching system is meant to describe any conventional hook and loop fastening system. These systems generally work by having the hook or loop portion entangling or interlocking in the corresponding loop or hook portion of the system. Although the term “Velcro™” is frequently misused to describe the hook and loop style fastening system and further may be used, the invention is not meant to be limited to the specific characteristics of Velcro™.

FIG. 4 illustrates another embodiment, wherein inclined member 30 may be disposed or otherwise retained within a first pocket 24 or a second pocket 25. In this configuration, inclined member 30 is typically retained against or in close proximity to back surface 22 by sliding inclined member 30 into one of pockets 24 or 25. Although not meant to be limiting, in one embodiment, pockets 24 and 25 are divided by a typically central divider 26 typically substantially disposed along the longitudinal axis of infant receiving member 10. In FIG. 4, divider 26 is shown created by stitching or otherwise engaging a material to back surface 22, thereby creating first and second pockets 24 and 25. Conceivably, this engagement could also be accomplished using a hook and loop fastener system as described above. The material and the manner of creating a plurality of pockets are not critical to the inventive concept and numerous known methods and materials may be used. Still further, a single pocket, a pair of pockets, or any plurality thereof may be used.

As shown in FIG. 5, inclined member 30 may be fabricated to be an integral part of infant receiving member 10 to form inclined infant receiving member 50. Alternatively, inclined member 30 may itself be an infant receiving member.

Harness 40 is typically utilized to secure an infant to infant receiving member 10, thereby preventing the infant from rolling over or otherwise rolling down the inclined surface of the system 2. As illustrated in FIG. 1, a three point harness may be used, wherein a first strap and a second strap laterally wrap over the torso of an infant and engage one another, while a third strap, substantially longitudinally, wraps over the torso of an infant and engages either the first or second strap, thereby securing the infant (FIG. 6). Additionally, a hook and loop style fastening system is typically utilized to secure the straps. Although, any fastening system which is generally well-known within the art may be utilized. Another embodiment is shown in FIG. 5, wherein the harness 40A includes a pair of straps. Further it is envisioned that a single strap could be used. Alternatively, more than three straps may also be used.

As described previously, the method of preventing positional plagiocephaly may be practiced using the inventive system. Broadly speaking, the method utilizes a system constructed in accordance with the present invention and comprises alternately tilting sideways a portion of the infant receiving member on which at least a portion of the infant is laid such that by tilting the portion of the infant receiving member underlying the infant, sideways, the infant will sleep with his/her head facing down the slope of the tilted mattress portion (FIG. 2). Because the infant generally lacks the muscles to move its head to sleep on the other side of its head, against the slope of the mattress, the infant will not sleep on the other side of its head. In this manner, the infant will sleep to one side of its head one night, and, when the infant is differently positioned or the inclined member positioned under the opposite portion of the infant receiving member, the infant will sleep on the other side of its head. By alternating the side of the infant's head on which the infant sleeps each night, or on some other periodic basis, the infant will not develop the flat spots in its skull that are symptomatic of positional plagiocephaly. The steps of tilting the head portion of the mattress to different sides every other night should be continued through about the first four to ten months after the infant's due date. Infants that are born premature or are neurologically impaired may be susceptible to a greater age.

As shown in FIG. 7, the system may be incorporated into a crib, cribette, cradle, bassinette, or any other structure in which an infant is typically placed in a generally horizontal position for an extended period of time.

The above description is considered that of the preferred embodiments only. Modification of the invention will occur to those skilled in the art and to those who make or use the invention. Therefore, it is understood that the embodiments shown in the drawings and described above are merely for illustrative purposes and not intended to limit the scope of the invention, which is defined by the following claims as interpreted according to the principles of patent law, including the doctrine of equivalents.
