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.

Claims

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.
