| Abstract | A readily bendable positioning aid, having a soft, spongy foam body for
supporting an infant. Once formed into the desired shape, the support
maintains its shape until reformed by the user. Disposed internally of the
foam body is an elongated, bendable lead rod that weights the body
sufficiently so that the support will remain in position about the infant
and will effectively constrain movement of the infant. |

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to positioning aids. More
particularly, the invention concerns a bendable infant support, having a
soft, spongy foam body for supporting a patient such as an infant. Once
formed into the desired shape, the support maintains its shape until
reformed by the user.
2. Discussion of the Invention
As infants reach an age where they first start to roll over and move about,
they can suffer serious injury if they roll off beds or the like, and if
they are not otherwise constrained in some manner to a safe location. In
the past, makeshift expedients such as pillows, cushions and like articles
have been placed around the infant to attempt to constrain the infant to a
particular location. Such expedients are unsatisfactory for many reasons,
not the least of which is that they can be very dangerous if they shift
into a position where the infant's face is covered in a manner to restrict
free breathing. Also, such expedients are generally ineffective in
constraining unwanted movement of the infant since the supports themselves
tend to easily shift.
The unique support of the present invention overcomes the drawbacks of the
prior art, makeshift expedients discussed in the preceding paragraph by
providing a novel, easily bendable, cushioned support that is weighted to
stay in place. The novel support of the present invention includes a soft
foam body within which a hermetically sealed, bendable rod is
encapsulated. The foam body is covered with a disposable cover, which is,
in turn, covered with a soft outer cloth cover which can be removed and
washed. The internally disposed, bendable core permits the support to be
easily formed into any desired shape so that the soft body portion thereof
can be closely formed about the infant. For example, the body can be
formed in a manner to surround and support the infant in a side-lying
position, or alternatively it can be formed to create a hammock-like
support to constrain the infant in a supine position. Due to the novel
character of the bendable rod, the body will retain its shape until
manually reshaped by the caregiver. The substantial weight of the
internally-disposed, bendable rod tends to effectively resist shifting of
the support as the patient moves. Because of the novel design of the
device it is readily usable with both infants and adults and uniquely
provides support to the patient at strategic locations.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an easily bendable,
soft cushioned infant support which can be safely formed about a patient
or an infant to provide increased security, comfort and restraint against
movement.
Another object of the invention is to provide an infant support of the
aforementioned character which is weighted to stay securely in place about
the infant.
Another object of the invention is to provide an infant support which is
covered first by a disposable cover and then by a soft cloth cover which
can be easily removed for washing.
Still another object of the invention is to provide an infant support of
the character described in the preceding paragraphs which promotes proper
physiologic flexion, facilitates mid-line orientation, improves
self-regulation and encourages self-comforting behavior.
Yet another object of the invention is to provide an infant support of the
character described, which is easy to use, easy to clean, easy to
transport from place to place and is inexpensive to manufacture.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a generally perspective view of one form of the positioning aid
the present invention.
FIG. 2 is a generally perspective view similar to FIG. 1 but showing the
outer cover of the device pulled back to expose the bendable rod assembly
which is encapsulated within the cushioned body portion of the device.
FIG. 3 is a cross-sectional view taken along lines 3--3 of FIG. 2.
FIG. 4 is a generally diagrammatic view illustrating the positioning aid
formed about an infant lying on its side.
FIG. 5 is a generally diagrammatic view illustrating the positioning aid
about an infant disposed in a supine position.
DESCRIPTION OF THE INVENTION
Referring to the drawings and particularly to FIGS. 1, 2 and 3, one form of
the positioning aid of the present invention is there illustrated and
comprises an elongated, yieldably deformable, cushioning portion 12 which
is covered by cover means of a character presently to be described.
Encapsulated within cushioning portion 12 is a bendable rod assembly
generally designated in FIG. 2 by the numeral 14.
As best seen in FIG. 3, bendable rod assembly 14 comprises a bendable rod
16 which is sealably encapsulated within an encapsulating means shown here
as an elongated, polyvinyal chloride plastic tube 18. A cap portion 18a
closes the outboard end of tube 18 in a manner to hermetically seal rod 16
within the tube. Rod 16 can be constructed of various bendable materials
such as metal and plastic, but for purposes of the present invention, lead
has proven most satisfactory because of its uniform bending
characteristics and its weight, which tends to resist shifting.
As best seen in FIGS. 2 and 3, rod assembly 14 is closely receivable within
an elongated, channel-like opening 20 which extends substantially the
length of cushioning portion 12. With this construction, assembly 14 can
be telescopically inserted into channel 20 to a position wherein it is
fully enclosed within the cushioning body of the device. This feature of
the invention permits the rod assembly to be reused when it is necessary
to replace the cushioning body.
In the present embodiment of the invention, the covering means comprises a
first cover in the form of a disposable polyester cover 22 (FIG. 3) which
is closely receivable over cushioning portion 12. This cover protects the
cushioning body and can be disposed of after each use. Surrounding cover
22 is a second cover, here shown as cloth cover 24. As best seen in FIG.
1, the forward, open end is closable by cooperating flaps 26 and 28 which
can be folded over the end of cushioning portion 12 and held securely in a
closed position by any type of suitable fastener, such as snap fastener
30. Covering 24, which can be conveniently slipped off of the cushioning
body, can be constructed of any suitable material such as cotton or
synthetic fiber cloth which can be easily washed by conventional means.
Cushioning portion 12 can be constructed of any suitable soft, spongy
material such as natural or synthetic rubber or it can be constructed from
a polymeric foam. Suitable polymeric foams can be prepared from virtually
any polymer by the introduction of a gas into a polymer matrix to provide
a cellular structure of desired consistency. Materials suitable for the
construction of cushioning portion 12 are readily commercially available
from a number of sources including The Dow Chemical Company.
In use, the positioning aid of the invention, can be easily formed into any
desired shape, including the shapes shown in FIGS. 4 and 5. Once formed
into the desired shape, the positioning aid will retain its shape until
reformed by the user. Because of the substantial weight provided by the
internally disposed rod assembly, the support will remain in position
about the infant and will effectively resist excessive movement.
When the outer cover 24 become soiled, it can be easily removed for
washing. If necessary, the inner cover can be removed and discarded.
Following replacement of the inner cover, the outer can then be
re-positioned about the body in the manner shown in FIG. 1.
Having now described the invention in detail in accordance with the
requirements of the patent statutes, those skilled in this art will have
no difficulty in making changes and modifications in the individual parts
or their relative assembly in order to meet specific requirements or
conditions. Such changes and modifications may be made without departing
from the scope and spirit of the invention, as set forth in the following
claims.
