| Abstract | A pillow of resilient material has a generally rotatable portion (cervical
roll) for supporting the cervical region of a user. With a user's neck
received across the pillow cervical roll and the user's head received on
the pillow, rotation of the cervical roll in conjunction with collapse of
angled chambers defined within the resilient pillow establishes traction
in the cervical region of the user. Once its internal chambers are
essentially fully collapsed, the pillow provides a generally continuous
support medium for optimized resilient support of the user's neck and
head, while maintaining a degree of cervical region traction with natural
cervical curvature achieved through curved support of the user's cervical
region across the cervical roll of the pillow. |

What is claimed is:
1. A traction pillow, comprising:
a generally integral body of resilient material having a substantially
solid cervical roll means situated generally along one side edge of said
body; and
a plurality of collapsible chamber means defined within said body by
angled, opposing walls which are directed generally towards another side
edge of said body which is situated opposite said one side edge thereof,
said chamber means being situated generally outside of said cervical roll
means;
wherein said cervical roll means and said chamber means functionally
respond to receipt of a patient's head on said pillow with the cervical
region of such patient received across said cervical roll means, in
conjunction with manipulation of said cervical roll means for rotation
towards said chamber means, for collapsing said chamber means, generally
in a direction away from said cervical roll means, so that said opposing
walls contact one another for substantially continuous resilient support
of a patient's head, and further for inducing a degree of traction
outwardly along such patient's spine while generally maintaining a normal
cervical curve of the patient.
2. A traction pillow as in claim 1, wherein said cervical roll means
includes an upper support surface with a plurality of channels defined
therein situated generally in alignment between said one and said another
body side edges, said channels dispersing pressure on such neck and
providing increased circulation of air therearound.
3. A traction pillow as in claim 1, wherein said cervical roll means
includes an upper support surface with a curved depression defined
therein, said depression being adapted for receipt of a patient's neck, so
that predetermined placement of a patient's neck and head on said traction
pillow may be obtained.
4. A traction pillow as in claim 1, wherein said cervical roll means and
said chamber means are operative for producing relatively soft traction
for purposes of tending to immobilize a patient, without producing a
therapeutic action of stretching the patient's spine an amount adequate to
separate intra-vertebral spaces therein.
5. A traction pillow as in claim 2, wherein said resilient material
comprises polyurethane foam, which has a coefficient of friction adequate
to permit distraction of a patient's head and neck received thereon
without the pillow slipping relative a surface on which the pillow is
supported.
6. A traction pillow as in claim 1, wherein said cervical roll means is
operative during rotation thereof towards said chamber means for lifting
the chin of a patient whose neck is received across said roll means,
whereby forward flexure of the patient's head is prevented, which forward
flexure could otherwise cause obstructed breathing of the patient.
7. A traction pillow as in claim 1, wherein said plurality of collapsible
chamber means comprise at least two chambers of a generally
parallelogram-shaped cross-section, when not collapsed, with a common
angled wall therebetween, said cross-sections of said chambers being
substantially constant across the lateral width of said traction pillow so
that collapse of said chambers results in folding of said
parallelogram-shaped cross-sections along the long axis of such shapes.
8. A traction pillow as in claim 1, further comprising a second
substantially solid cervical roll means situated essentially along said
another side edge of said body opposite said one side edge thereof, said
two cervical roll means having prominent lobe aspects which project to
different degrees on opposite sides of said traction pillow, whereby said
traction pillow may be reversed for collapsible operation with selected of
said cervical roll means received under the neck of a patient, thus
providing a dual-size, reversible pillow in a single, unitary
construction.
9. A pillow for supporting the head and neck of a user while controllably
inducing a degree of traction in the cervical region of such user without
disrupting normal cervical curvature of such user, said pillow comprising:
a resilient body of material defining two parallel lobes separated by a
relative trough, one of said lobes being larger than the other and
defining a substantially solid cervical roll means for receipt of a user's
neck region thereacross with the head of such user supported generally in
said trough; and
at least one collapsible chamber means, defined in said body generally
beneath said trough thereof, and situated adjacent and substantially
parallel to said cervical roll means, said chamber means including angled
opposing wall members which are initially separated from one another but
which generally contact one another by collapsing action of said chamber
means responsive to receipt of the head of a user on said trough with the
user's neck received across said cervical roll means, in conjunction with
twisting of said cervical roll means towards said chamber means, for
imparting an amount of traction to the cervical region of such user, while
the normal cervical curvature thereof is maintained through curved support
thereof across said cervical roll means, and for providing generally
continuous resilient support of the user's head.
10. A pillow as in claim 9, wherein said chamber means includes a plurality
of sub-chambers, each of which are defined by parallel, angled wall
members situated across the lateral width of said pillow, all such
sub-chambers collapsing upon receipt of a user's head and neck on said
pillow so that said opposing walls thereof come into mutual contact for
optimized dispersion of pressure on the user with said resilient body
material, whereby upper support walls of said sub-chambers are generally
continuously supported with resilient material.
11. A pillow as in claim 9, wherein said cervical roll means and said
chamber means impart an amount of traction equivalent to less than 10
pounds of force acting outwardly along the user's cervical region.
12. A pillow as in claim 9, wherein the surface of the cervical roll means
generally frictionally engages a user's head and neck to the extent same
contacts said roll means, so that twisting of said cervical roll means
towards said chamber means is operative to lift the user's chin upward to
prevent obstruction of the user's breathing.
13. A pillow as in claim 9, wherein said relatively larger lobe projects
outwardly on one side of said pillow, and the other lobe projects
outwardly on an opposite side of said pillow, whereby said pillow may be
reversed for use with different size users, with a selected one of said
two lobes serving as a cervical roll means for receipt of a user's neck
thereacross.
14. A method of inducing a degree of traction in the cervical region of a
user whose head and neck are supported on a pillow, comprising the steps
of:
providing a pillow of resilient material, said pillow including a head and
neck upper support surface, a substantially solid cervical roll situated
along one side edge of said pillow and defining a generally raised lobe
relative said support surface, and further including a plurality of
chambers formed within said pillow by opposing side-walls which are angled
away from said cervical roll;
receiving a user's head and neck on said pillow with the head generally
supported on said upper surface and the neck received across said cervical
roll; and
rotatably manipulating said cervical roll towards said chambers while the
user's head and neck are received on said pillow, until said chambers are
generally collapsed in a direction outward along the user's cervical
region such that opposing forming side-walls thereof are brought into
contact to define generally continuous resilient material, which induces
and maintains a degree of traction in such cervical region while
maintaining the natural curvature of such region through curved support
thereof across said raised lobe provided with said cervical roll.
15. A method as in claim 14, wherein:
said providing step includes using polyurethane for said resilient
material, said polyurethane having a coefficient of friction adequate for
engaging a user support surface generally without slippage after said
cervical roll rotation step is performed, whereby said induced degree of
traction is maintained.
16. A method as in claim 14, wherein:
said providing step further includes providing a second support surface on
an opposite side of said pillow from said upper support surface thereof,
and providing a second cervical roll on a side edge of said pillow
opposite from said one edge thereof, said second cervical roll forming a
second raised lobe projecting from said second support surface to a degree
less than said generally raised lobe projects relative said upper support
surface; and
wherein said method further comprises the step of selecting one or the
other of said support surfaces for receiving the head and neck of the user
with the appropriate size lobe supporting the cervical region of said
user, whereby a reversible, dual-sized pillow may be provided in a single,
unitary construction for inducing a degree of traction with users having
different sized head and neck morphology.
17. A method as in claim 14, wherein said rotatable manipulation step
further tends to at least slightly lift the chin of the user, whereby
obstruction of the user's breathing is prevented.
18. A method of establishing and maintaining relatively low amounts of
traction in the cervical region of a patient, comprising the steps of:
providing a patient support surface, such as a bed;
providing a traction pillow, comprising a generally rectangular
construction of resilient foamed material, having a generally flat lower
surface for receipt on the patient support surface, and a profiled upper
surface including two relative lobes of different sizes on opposing side
edges of said pillow and a relative trough therebetween, said lobes and
said trough extending parallel to one another across the lateral width of
said pillow, said pillow further defining internal chambers having angled
walls directed for collapse of said chambers away from the larger of said
lobes;
placing said traction pillow on said patient support surface relatively
adjacent an end of said patient support surface, and with said profiled
upper surface of said pillow facing upward, and with said larger lobe
thereof placed nearer the center of said patient support surface than the
smaller of said lobes;
situating a patient on said patient support surface in a generally supine
position, and with the patient's head and neck supported on said traction
pillow, the patient's neck in particular being received across said larger
lobe, with such patient placement on said pillow tending to at least
partially collapse said pillow chambers so as to pull outwardly along the
patient's cervical region; and
thereafter rotatably manipulating said larger lobe by twisting same towards
said pillow chambers, so as to more fully collapse same, and so as to more
positively establish a degree of traction in the patient's cervical
region, whereby the curvature of said larger lobe supporting the patient's
neck maintains natural cervical curvature of the patient, while friction
between said pillow lower surface and said patient support surface
maintains traction established with said pillow and said situating and
twisting steps. |

BACKGROUND OF THE INVENTION
This invention generally concerns a pillow preferably comprised of
resilient material, and a method of use for same, and more particularly
concerns a pillow for inducing an amount of traction in a user, and a
related method of establishing such traction.
The neck or cervical region of a person has a natural, i.e. normal,
curvature, which is generally concave towards the back of the person.
Conventional traction techniques, such as may be used with patients in a
hospital setting or others undergoing treatment, involves immobilization
of a selected limb or region of a patient, usually by application of a
continuous stretching force to the selected limb or region (sometimes
involving the entire body). Whenever such traction involves the cervical
(i.e. neck) region of a patient, the natural or normal curvature of such
region is often lost or distorted to a certain degree. In other words, the
neck region tends to be flattened out. Application of any degree of
loading (i.e. traction) to the cervical region while it is in a position
other than its normal curvature can in the best case be uncomfortable for
the patient, and in the worst case actually cause or aggravate injuries in
the cervical region.
Use of traction for a patient can be indicated for a variety of reasons.
One typical scenario in which traction might be applied is whenever a
patient experiences muscle spasms in the back or neck. The spasms might be
treated with various amounts of therapeutic traction, drug therapies,
and/or various combinations of both such therapies.
Therapeutic benefit from traction, in the context intended herewith, means
as ordinarily accepted that the amount of traction must be adequate to
actually physically separate the intra-vertebral positions, which is
therapeutic in the sense that it tends to relieve pressure on individual
vertebra. However, traction can have more general beneficial effects on a
patient when used in degrees less than that achieving such intra-vertebral
separation. Such so-called "soft" traction (i.e. less than a "therapeutic"
amount) may, for example, benefit a patient by psychologically
immobilizing the patient achieve desired bed rest. A relatively light
physical force is also provided in association with desired patient
placement.
Another benefit of such soft traction is its potential to be achieved with
less imposing machinery or mechanisms than heretofore used for extensive
traction setups. Hence, particularly in a hospital setting, soft traction
may be perceived by the patient as having greater aesthetic appeal, that
is as being more user-friendly, further contributing to beneficial
relaxation and bed rest for the patient. The cost of providing soft
traction may also be significantly lower.
Yet another factor which may contribute to the degree of relaxation
experienced by a patient, and the degree of comfort of the patient
(particularly when concerning relatively extended periods of bed rest) is
the relative dispersion of pressure between the patient and support
surfaces | | |
