Abstract
An infant positioning device which provides the ability to move an infant, a preterm infant, and/or a newborn between and including a supine, prone, or side-lying position, with little or no tactile stimulation of the infant caused by human touch.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates generally to devices and methods for supporting infants and, in particular, to devices and methods for positioning infants which avoids undesired tactile stimulation of the infant.




2. Description of Related Art




The sense of touch in a human being is highly developed in utero. Therefore, even the very immature preterm neonate has an acute tactile sensitivity. Tactile stimulation (i.e. human touch) of a neonate can both arouse and soothe. In most cases, preterm neonates thrive from tactile stimulation. However, in some instances, tactile stimulation of a neonate, especially an ill preterm neonate, may result in significant physiological consequences. For example, a physiologically stable preterm neonate, when subjected to human touch, may be benefited with increased activity, a faster regaining of birth weight, less crying, and better socialization with parents and caregivers. However, in a physiologically unstable neonate, the benefits of touch may be outweighed by detrimental consequences, which may include blood pressure changes, alterations in cerebral blood flow, hypoxia as well as other stress behaviors. Premature neonates who exhibit such symptoms when touched are usually referred to as “negative touch” or minimum stimulation patients.




In some cases, excessive tactile stimulation, which is continuously repeated, may cause the neonate to develop a touch aversion—an association of human touch with pain or extreme discomfort. Preterm neonates that have developed an aversion to touch typically cry uncontrollably, squirm away, flail arms and legs, and recoil when touched. To avoid these consequences, preterm neonates that exhibit symptoms of touch aversion or are negative touch should receive care that includes tactile interventions, such as minimal handling and body containment.




One particular aspect in the care of preterm neonates that generally requires lots of touching and handling is that of positioning. The benefit of adequate and supportive body positioning for preterm and full term neonates is well known. For example, proper positioning of the preterm neonate has been shown in some studies to greatly reduce the long-term affects of prematurity. Moreover, proper positioning increases feelings of security, promotes quieting and self-control, enhances psychological stability, promotes energy conservation, reduces psychological and behavioral stress, and enables stress to be better endured. Also, the preterm neonate should be provided with a variety of positions to prevent the negative consequences of, for example, joint stretching and/or to promote and facilitate the development of muscle tone. These positions may generally range between and include a prone, a supine, and a side-lying position. It has also been shown that preterm neonates thrive when positioned to achieve full body containment, known as “nesting.”




Most neonate body positioning is accomplished in a make-shift manner that usually requires touching of the neonate. Unfortunately, for preterm neonates who suffer from symptoms related to negative touch or touch aversion, make-shift manners for providing positioning intervention may create a high degree of tactile stimulation caused by human touch. The excessive handling may counter any benefit derived from the positioning intervention.




For these reasons, what is needed is an infant positioning device which provides adequate support for an infant, including a preterm infant. The device should also provide a caregiver an ability for moving an infant between and including a supine, prone, or side-lying position, with little or no tactile stimulation for the infant caused by direct human touch.




SUMMARY OF THE INVENTION




In the present invention an infant positioning device provides support to an infant. The present invention further provides the caregiver the ability to move the infant between and including a supine, a prone, or a side-lying position, with minimal or no tactile stimulation of the infant caused by direct human touch.




In one aspect of the present invention a device is provided for supporting and positioning a neonate. The device includes a substantially conformable member and a plurality of support members. Each support member is moveable from a first position to a second position to facilitate the positioning of the neonate placed on the conformable member.




In another aspect of the present invention, a positioning device is provided for positioning an infant. The device includes a substantially conforming member. Coupled to the conformable member are at least two support members, which define a torso area on a portion of the conformable member. Each of the support members is moveable from a first position to a second position. In response to the movement of at least one of the support members, the infant is repositionable from a first posture to a second posture.




In yet another aspect of the present invention, a method for repositioning an infant is provided. The method includes positioning an infant on a positioner in a first posture; and moving a support member from a first position to a second position to reposition the infant from the first posture to a second posture.




In each aspect of the invention the positioning of the neonate is accomplished while avoiding physical contact between a caregiver and the neonate.

As best understood with reference to

FIG. 1

, support members


18


,


20


,


22


, and


24


may be arranged to form approximately a rectangle, with conformable support member


12


being placed over the support members. With conformable member


12


in position over the support members, support members


18


,


20


,


22


, and


24


form convoluted portions


28


, which define a recessed central torso area


26


. Torso area


26


is sized and shaped by manually positioning support members


18


,


20


,


22


, and


24


. Preferably, the torso area is shaped for receiving the torso of an infant, including a preterm neonate. Although support members


18


,


20


,


22


, and


24


, have been shown arranged in a rectangle, any other geometric arrangement is considered to be within the scope of the present invention. For example, support members


18


,


20


,


22


, and


24


may be positioned into a circular, a square, or a triangular arrangement.





FIGS. 2A and 2B

, illustrate a top and bottom view, respectively, of infant positioning device


10


.

FIG. 2A

, shows conformable support member


12


, placed over support members


18


,


20


,


22


, and


24


(not shown), to form convoluted areas


28


, which surround torso area


26


. Preferably, conformable member


12


can include any substantially flexible and comfortable material that can conform to the arrangement of support members


18


,


20


,


22


, and


24


and has a density suitable for cushioning the neonate. Conformable member


12


may include, but is not limited to a padded blanket or a thin padded mattress. Although, conformable member


12


is shown in

FIG. 2A

as substantially a rectangular shaped member, member


12


may include any suitable geometric shape, which can be used for the intended purpose of conformable member


12


as described herein.





FIG. 2B

, shows support members


18


,


20


,


22


, and


24


coupled to bottom surface


32


of conformable member


12


. Lateral support members


18


and


20


are coupled at opposite sides of underside


32


, and extend generally from head end


14


toward foot end


16


of positioner


10


. Lateral members


18


and


20


restrict lateral movement of an infant placed in torso area


26


of positioner


10


. Typically, lateral members


18


and


20


extend at least three-quarters of the distance of the lateral length of conformable member


12


; preferably the lateral members extend at least half of the distance. In one embodiment, lateral support members


18


and


20


may have a length of between about 10 and 20 inches, preferably about 12 inches. Although, lateral support members


18


and


20


are shown in

FIG. 2B

as having approximately equal lengths, in an alternative embodiment, lateral members


18


and


20


may have different lengths.




Transverse member


22


is coupled to under surface


32


of conformable member


12


at head end


14


. Lateral support members


18


and


20


cooperate with transverse member


22


to form torso area


26


. In one embodiment, torso area


26


can be a substantially U-shaped area, framed on all sides by convoluted areas


28


. Optionally, foot support member


24


is disposed opposite to transverse member


22


at the foot end


16


of conformable member


12


. Foot member


24


acts to close in the U-shaped area defining torso area


26


. In cooperation with the other support members, foot member


24


allows restriction of all movement of the neonate. This arrangement is generally referred to as a “nest” and provides the neonate with full body containment. Foot member


24


has been described herein as being optional; however, it should be understood that in alternative embodiments of positioner


10


, each support member


18


,


20


,


22


, and


24


is removable from conformable member


12


, which makes the use of any one support member optional. For example, a caregiver may find it necessary for a given positioning intervention to use only one lateral support member in cooperation with the transverse and foot support members.




Lateral support members


18


,


20


, transverse member


22


, and foot support member


24


are each typically made of a resilient material that can be conformed to a shape that provides support to the infant placed in torso area


26


. Support members


18


,


20


,


22


, and


24


may be constructed in a manner similar to what are commonly referred to as bead bags or else pillows. In one embodiment, illustrated in

FIG. 3A

, each support member may be made from a collapsible bag


42


that contains a filler material


44


. In this embodiment, collapsible bag


42


may contain polystyrene beads


44


, or optionally, bag


42


may contain filler materials


44


, such as a polysilicon gel, feathers, air, liquid, resilient foam and flaxseed. The outer material of bag


42


may be made of any resilient and conformable material that is capable of holding contents within the bag, such as the above-described filler materials. Examples of bag materials include vinyl, plastic, tightly woven cloth, fleece, and the like. As shown in

FIG. 3B

, end


46


of bag


40


may be sealed in a conventional manner that allows for securely holding the contents. For example, a plastic bag


42


may be heat sealed or glued, whereas a cloth bag


42


may be stitched.




In the embodiment illustrated in

FIG. 1

, support members


18


,


20


,


22


, and


24


are cylindrical in shape. However, the length, width, diameter, and overall shape of the support members may be varied to provide any desired arrangement. For example, support member


40


(

FIG. 3A

) may be constructed in lengths and diameters that allow for adequate support of infants of variable sizes and shapes. In most cases, the support members can be at least half as long as the length of the torso portion of the neonate. Since the support members are removable and replaceable, it may be appreciated by those of skill in the art that as the neonate grows, differently sized and shaped support members may be used to accommodate such growth.




Each support member


18


,


20


,


22


, and


24


may be directly or indirectly coupled to conformable member


12


. In one embodiment, support members


18


,


20


,


22


, and


24


are coupled to conformable member


12


in a manner that allows the support members to be movable. Preferably, the movement includes pivoting or swinging support members


18


,


20


,


22


, and


24


from the coupling point. In one embodiment, shown in

FIGS. 4A and 4B

, an exemplary support member


50


is shown coupled to conformable member


12


indirectly through hollow sleeve


52


. Hollow sleeve


52


may be coupled to member


12


using any conventional fastening means


54


, which may include sewing sleeve


52


to member


12


. Alternatively, sleeve


52


may be coupled to member


12


using, for example, a VELCRO® fastener, a tongue and groove device, a zipper, buttons, snaps, or other similar fastening means. Support member


50


is removably insertable into hollow sleeve


52


. Optionally, sleeve


52


may be closeable at ends


56


and


58


using conventional closing means


57


, such as VELCRO® fasteners, a zipper, buttons, snaps, or other similar means, which facilitate holding support member


50


in sleeve


52


.




Support member


50


is moveable between a first and a second position. Typically, the motion is a pivoting or swinging movement in the direction generally indicated by arrow


60


in FIG.


4


B. Optionally, fastening means


54


may also include an extended strip of material, as shown in

FIG. 4E

, which allows support member


50


not only to swing or pivot, but to be moved a distance D relative to the coupling point of fastening means


54


. In an alternative embodiment, as illustrated in

FIGS. 4C and 4D

, support member


50


may be coupled directly to member


12


using any one of the above-described fastening means


54


or their equivalent.





FIGS. 5A-5C

illustrate an example, with no intention to limit the invention thereby, an embodiment of the operation of positioner


10


. In this embodiment, positioner


10


may be manipulated (i.e., rotated, pivoted, moved, etc.) so as to reposition a neonate N placed on positioner


10


. Preferably, the infant is repositioned without requiring the caregiver to directly touch the infant.





FIGS. 5A-5C

show a rear end view of positioner


10


with a neonate N positioned in torso area


26


. Additional support members are not shown for ease of illustration. In this example, neonate N is in a side-lying position as indicated by the direction of the neonate's feet. To support neonate N, support members


18


and


20


are snugged up against neonate N, and may optionally be turned in under the infant. Once neonate N is placed in torso area


26


, support members


18


and


20


may be manipulated from below conformable member


12


, such that there is no direct touching necessary between the neonate and the caregiver.




To reposition neonate N, torso area


26


may be expanded by pivoting, swinging, or otherwise moving one or both of support members


18


and


20


. For example, as shown in

FIG. 5B

, support member


20


is pivoted or rolled, such that torso area


26


is made larger, so neonate N can be rolled over in the direction indicated by arrow


64


. Preferably, neonate N rolls as member


20


is being moved away, so that neonate N is supported at all times during the repositioning maneuver. In this example, the neonate is made prone. However, alternatively as indicated in

FIG. 5C

, neonate N may be rolled back to a side lying-position, if the caregiver so desires. In this example, to perform the maneuver of

FIG. 5C

, support member


18


is rolled under in the direction indicated by arrow


64


, such that member


18


pushes under the neonate's body, thereby forcing the neonate to continue to roll.




As shown in

FIG. 5D

, members


18


and


20


may be moved back so as to be snugged against neonate N once neonate N is in the desired position. Those who are skilled in the art will appreciate that during the movement of support members


18


and


20


, the neonate N, whether in a prone, supine, or side-lying position, or moving therebetween, is adequately supported and protected by the support members. Moreover, because in each repositioning maneuver described above, support members


18


and


20


are moved or manipulated from below conformable surface


12


, one of skill in the art should also appreciate that there is no need for the caregiver to have to directly touch or tactily stimulate neonate N.




Given the above example, it will also be appreciated that the length and diameter of the support members can be changed and still cooperate with each other to perform the positioning and repositioning function. Accordingly, different support members of different lengths and different diameters can be used together as the neonate grows. Also by using support members of different lengths and different diameters, different neonates can use the same positioning device. By allowing for a variation of lengths and diameters, the care giver is given greater latitude in performing the new positioning function which suites the personal needs of the neonate and/or the care giver.





FIGS. 6A-6C

illustrate a method for moving an infant I between a first posture and a second posture. As shown in

FIG. 6A

, conformable member


12


may be wrapped about lateral support members


18


and


20


to form convoluted areas


76


and


77


, such that torso area


26


is formed therebetween. Infant I is placed on conformable member


12


in torso area


26


in either a supine, a prone, or a side-lying position or in some position in-between. Each of the lateral support members may then be positioned snugly against infant I. Once the infant I is to be moved, either lateral member


18


or


20


, and in some instances both, may be unrolled in the direction shown by arrow


70


, such that convolution


77


is unfurled. Infant I can then simultaneously, or when desired, roll in the direction indicated by arrow


72


from a side-lying position to a prone position or else back to a side-lying position. Once infant I has been moved, member


20


may be re-rolled as indicated by arrows


74


, such that convolution


77


is reformed by member


20


and is snugly supporting infant I.




Optionally, transverse member


22


, foot member


24


, or both, may have been added to positioner


10


in the above embodiment. As described above, transverse member


22


and foot member


24


may be rolled in and out to provide support and facilitate positioning of neonate N.





FIGS. 7A and 7B

, show an alternative embodiment of the present invention. In this embodiment, positioner


80


includes multiple lateral members


82


,


84


,


86


, and


88


, where members


82


and


84


are disposed opposite members


86


and


88


. Conformable member


12


may have slits


92


and


94


, which are directed in away from an edge of member


12


towards torso area


26


. As shown in

FIG. 7B

, slits


92


and


94


allow members


82


,


84


,


86


, and


88


to be moved independently of one another either in or out from torso area


26


to provide the caregiver with additional options for positioning and supporting infant I. In one embodiment, members


84


and


88


may be pivotally attached or hinged to members


82


and


86


, respectively.
