HEAD AND/OR NECK SUPPORT DEVICE AND METHOD
The present invention relates to spinal support and a means for support and alignment for the neck in the side, supine or semi prone or prone positions comprising; supporting the user's head and/or neck in a first user position with a first adjustable support means adapted to locate the user's head and/or neck at a first height relative to a supporting surface for the user; supporting the user's head and/or neck in a second user position with a second adjustable support means adapted to locate the user's head and/or neck at a second height relative to a supporting surface for the user; wherein the first and second heights relative to the supporting surface for the user are substantially different such that substantially constant cervical spinal alignment for the user is maintained in both positions.
This application claims priority to Australian Provisional Patent Application No. 2010904735 in the name of Tri-cycle Pty Ltd, which was filed on 25 Oct. 2010, entitled “Method, System and Apparatus for Support” and Australian Provisional Patent Application No. 2011904017 in the name of Tri-cycle Pty Ltd, which was filed on 30 Sep. 2011 and also entitled “Method, System and Apparatus for Support” and the specifications thereof are incorporated herein by reference in their entirety and for all purposes.
FIELD OF INVENTIONThe present invention relates to spinal support. In particular, in one form the present invention relates to a method, system and apparatus providing support for the head, neck and/or upper spine in a resting, sleeping or generally horizontal position. In one particular form, the invention relates to a means for providing support and alignment for the neck in the side, supine or semi prone or prone positions. While it will be convenient to hereinafter describe the invention in relation to its use as a structure for providing adjustable support to the neck, it should be appreciated that the present invention is not limited to that use, only.
BACKGROUND ARTThroughout this specification the use of the word “inventor” in singular form may be taken as reference to one (singular) inventor or more than one (plural) inventor of the present invention.
It is to be appreciated that any discussion of documents, devices, acts or knowledge in this specification is included to explain the context of the present invention. Further, the discussion throughout this specification comes about due to the realisation of the inventor and/or the identification of certain related art problems by the inventor. Moreover, any discussion of material such as documents, devices, acts or knowledge in this specification is included to explain the context of the invention in terms of the inventor's knowledge and experience and, accordingly, any such discussion should not be taken as an admission that any of the material forms part of the prior art base or the common general knowledge in the relevant art in Australia, or elsewhere, on or before the priority date of the disclosure and claims herein.
In practice as a physiotherapist in the field of spinal manipulative physiotherapy, the inventor has recognised that a cause of neck pain may be inappropriate pillows or inadequate support to the upper spine when resting or sleeping. However, it is also important to realise that people with not only painful conditions of the neck but also those with asymptomatic necks may have difficulty in finding a suitable pillow which will provide for support and comfort to the neck and upper spine and which can cater to the natural change in position of a person as they sleep or rest in the horizontal, including particularly the side and supine (on back) positions.
It is to be noted that height in this context does not specifically relate to a vertical component, only, of separation from the resting surface S but rather the actual distance (or vectorial sum of vertical and horizontal distances) between the head and resting surface S. In other words, whereas the horizontal disposition of the resting surface S in
Generally, a convex surface of the skull does not rest well on a flat surface and, accordingly, the pivoting point of the head, as described above, means that varying heights may be required for a pillow to make it suitable for supporting the neck and upper spine in varying positions. Conversely, this might not be an issue if the head was round with a central pivot point.
In the past, manufacturers have tried to solve these issues by using contour pillows to assist with support but this does not necessarily solve the problems of having differing support needs in different positions. Contour pillows allow for increased neck support but do not necessarily vary support with a change in height of the subject's head. Pillows of the prior art that are contoured in a particular form or moulded in a certain way often have limited flexibility and do not allow free movement during sleep. They may also limit the positions the user may take during rest and sleep, and this can cause discomfort.
Other solutions have involved the trialling of air and water adjusting devices to assist with head position but this does not solve the problem outlined above. The advent of memory foam has assisted but not solved the entire issue noted above. For example, the use of different materials has addressed the ability for a pillow to conform to a single sleeping position but does not accommodate more than one sleep or rest position as the properties of memory foam or other such materials do not adequately address the height differential issue noted above with respect to multiple positions. Further, the use of memory foam does not allow for enough height reduction or gain due to the behaviour or capacity of the material itself. Also, memory foam does not necessarily deform to a fixed position. Generally, memory foam only responds to weight pressure not the position of the resting subject and its properties may change depending on temperature. Memory foam allows for the height of a pillow or cushion from such material to adjust to pressure. The height issue is still not solved in both supine and sidelye or prone and semi-prone positions.
Furthermore, there are a number of specific devices and measures that are used in healthcare and/or for well being that have not necessarily been successfully integrated with the use of cushions or pillows in supporting the head, neck and upper spine. For example, sleep apnea (CPAP) masks, as would be recognised by the person skilled in the art, are designed for their own specific purpose and whilst they are also designed for use during sleep, they may be uncomfortable. As another example, there is also a need to cater for those who require immobilization for neck fractures, neck surgery, chronic pain or upper thoracic injuries. In this instance there are immobilisation devices such as, for example, a halo thoracic immobilization device as would be recogninsed by the person skilled in the art, which are cumbersome for the patient that wants to rest or sleep.
Apart from therapeutic devices as noted above, there may be other devices and consumer products that users may wish to have incorporated into a device for providing support whilst resting or sleeping, such as for example, devices for listening to music and or radio. Ordinarily these devices, if they can be worn by a user or located close to the person's ears, for example, then they only tend to be a hindrance to the comfort of the person when seeking a cushioned support for their head, neck, shoulders and upper spine.
SUMMARY OF INVENTIONAn object of embodiments of the present invention is to provide for adjustable support for the head, neck, or upper spine in the side, supine, prone and semi-prone positions.
It is also an object of the embodiments described herein to overcome or alleviate at least one of the above noted drawbacks of related art systems or to at least provide a useful alternative to related art systems.
In a first aspect of embodiments described herein there is provided a head and/or neck support device comprising:
-
- a frame member for supporting the head and/or upper neck of a user, the frame member adapted to be operatively associated with first and second adjustable support means;
- wherein the first adjustable support means is adapted to provide support for the user's head and/or neck in the supine or prone position and the second adjustable support means is adapted to provide support for the user's head and/or neck in the side lying or semi-prone position such that cervical spinal alignment is substantially constant in both supine and side lying positions.
The first and second adjustable support means, in combination, are preferably adapted to provide first and second heights, respectively, for the user's head and/or neck with respect to a supporting surface for the support device in both the supine and side lying positions, for example, where said first and second heights are different in order to maintain a substantially constant cervical spinal alignment for the user.
The first and second adjustable support means may be biased to provide self adjustment under load of the weight of the user's head and/or neck. In other words, the first and second adjustable support means are biased to provide height adjustment under load of the weight of the user's head and/or neck so as to maintain a substantially constant cervical spinal alignment for the user moving from one to another of a combination of side, supine, semi prone or prone positions.
Furthermore in a preferred embodiment, the first and second adjustable support means, in combination, are operatively associated to maintain substantially constant cervical spinal alignment during movement of the user from one position to another position.
Preferably, the first adjustable support means comprises a single mechanism located within a base of the frame member.
Furthermore, the second adjustable support means may comprise at least one other and preferably two mechanisms each located within respective side walls or lateral wings of the frame member.
Preferably, the frame member is further adapted to house cushioning means for supporting contact with the user's head and/or neck. In preferred embodiments the cushioning means comprises foam or memory foam or like material.
The frame member may be further adapted for attachment of at least one therapeutic device. The at least one therapeutic device may comprise a CPAP device.
The frame member may be embodied in a number of forms including but not limited to the form of a flat plate or in a preferred embodiment as a shell that may be deformed by integral or attachable adjustable means. The frame member may also be embodied as an orthotic. In the context of the present description an orthotic may be taken as an appliance designed to straighten or support a body part or a device or brace to control, correct, or compensate for an anatomical deformity, as would be recogninsed by the person skilled in the art.
In another aspect of embodiments described herein there is provided a method of supporting the head and/or neck of a user comprising the steps of:
-
- supporting the user's head and/or neck in a first user position with a first adjustable support means adapted to locate the user's head and/or neck at a first height relative to a supporting surface for the user;
- supporting the user's head and/or neck in a second user position with a second adjustable support means adapted to locate the user's head and/or neck at a second height relative to a supporting surface for the user;
- wherein the first and second heights relative to the supporting surface for the user differ to the extent that substantially constant cervical spinal alignment for the user is maintained in both user positions. Reference to both user positions may comprise a supine or side lying position for the first and second user positions, respectively. Alternatively, reference to both user positions may comprise a prone or semi-prone position for the first and second user positions, respectively.
The first and second adjustable support means may be biased to provide a self adjustment of height under load of the weight of the user's head and/or neck.
In a preferred embodiment, as noted above, the first user position is the supine position and the second user position is a side lying position. Alternatively, in another embodiment, the first user position is the prone position and the second position may also allow for a semi prone sleeping position.
Furthermore in preferred embodiments, the first and second adjustable support means, in combination, are operatively associated to maintain substantially constant cervical spinal alignment during movement of the user from one position, i.e. supine or side lying, to the to the other position, i.e. side lying or supine, respectively.
In another aspect of the embodiments described herein there is provided a support device wherein the frame comprises a deformable shell.
In this preferred embodiment, the first and second adjustable support means may be integral to the shell. The support device, in this aspect of embodiments may further comprise strap means extending between the sides of the shell, the strap means being of adjustable length wherein, the arrangement being such that tension applied to the strap means causes the shell to deform to define a height of the support surface. The unit may have one or more areas of height adjustment. The strap means may comprise a plurality of straps spaced between the edges of the shell each strap being independently adjustable in length. Further, the strap means may comprise a plurality of straps spaced between the edges of the shell where the length of the straps are adjustable in groups. Furthermore, the strap means may be rigid, semi rigid and/or elastic.
In this aspect of embodiments, apertures may be provided in the sides of the shell for receiving the strap means. The rear of the shell may comprise at least one transversely extending slot therethrough. The at least one transverse slot may be configured to define at least one transverse land, wherein the at least one transverse land may be adapted to be grasped to assist in adjusting the strap means. The at least one transverse land preferably supports means thereon for adjustability securing a free end portion of the strap means.
The support may further comprise at least one stabilising bar formed from an integral portion of the shell and this may be adapted to remain in line with a supporting surface when the shell is deformed. Preferably, the support is in the form of an outer removable support cushion adapted for placement against a resting surface or device.
Other aspects and preferred forms are disclosed in the specification and/or defined in the appended claims, forming a part of the description of the invention.
In essence, embodiments of the present invention stem from the realization that the height required for various positions when resting or sleeping such as, for example, supine (back sleeping) and side sleeping is different as a consequence of several anatomical variables including head size, shape, shoulder width, curve of the thoracic spine and, as such the use of a device which acts as a medium between the convex skull or neck and the flat resting surface should gradually accommodate distance from resting surface to point of axis along with a self levelling height adjusting device.
In preferred embodiments the present invention combines the use of positioning/levelling devices along with a solid device to accommodate to the change in positions along with the comfort factor of memory foam to ensure final comfort and slight accommodation.
Advantages provided by embodiments of the present invention comprise the following:
-
- Correct positioning device ensures spinal alignment in side lying and supine (on back) this allows the muscles to relax and allows any irritated, degenerative and arthritic joints the ability to avoid aggravation;
- Ability to partially immobilize neck or head movements;
- Ability to provide attachment points for auxiliary devices including consumer products or therapeutic medical devices such as CPAP masks/tubes/sleep apnea devices;
- A cut out on an orthotic embodiment between the neck and the shoulder assists in correct positioning of the neck by ensuring maximum support of the neck and maintaining a neutral supported spine.
- The use of self adjusting stabilising bars allow for an inner frame/shell and supporting straps to remain horizontal to the support surface.
Further scope of applicability of embodiments of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the disclosure herein will become apparent to those skilled in the art from this detailed description.
Further disclosure, objects, advantages and aspects of preferred and other embodiments of the present invention may be better understood by those skilled in the relevant art by reference to the following description of embodiments taken in conjunction with the accompanying drawings, which are given by way of illustration only, and thus are not limitative of the disclosure herein, and in which:
In one preferred embodiment of the present invention there is provided an orthotic pillow device 100, the internal structure of which is shown in
Inbuilt adjusting mechanisms then ensure correct resting position when the side, supine position or other position(s) is matched. Advantageously, adjustments are provided to ensure optimum neck support for back and side sleepers. The unique shape, inbuilt mechanism and contour of the orthotic device provides an optimal solution for people with sleep difficulties as well as being a single solution for all necks of all ages.
With reference to
Firstly the use of an orthotic like structure 100 enables the accommodation of the different arcs of rotation about the central access of rotation, “A”, to maintain a neutral spine position allowing for shoulder or back position. This device enables the smooth transition from supine to side, for example. Generally, the orthotic structure 100 comprises a base B and at least two side walls, SW, best shown in
Secondly manual or automated (for example biased) adjusting devices 200, as shown in
Thirdly the use of memory foam 300 allows for contact comfort of the head to the solid adjustable devices 200. By way of example,
It is noted that when the person is weight bearing with the head on a surface the adjusting device 200 takes 100% of the pressure and the orthotic structure 100 moves relative to the device. This enables the accurate position to be attained whilst ensuring that the head is not too encapsulated within the orthotic 100.
-
- Arc1—the arc of head radius from axis to side position due to wider shoulder than trunk width;
- Arc2—the arc of head radius to supine position and;
- HS—cross sectional head shape.
Also in
The solid orthotic structure 100 enables attachment of CPAP masks, sleep apnea devices and the insertion of speakers is also envisaged. This will be attached by a standard fixation method to enable universal application.
Details of suggested adjusting device 200:—This will be built into the orthotic and mounted on side apertures 201 for instance and form an enclosed contact area. A minimum of three adjustable support devices 200 are included, namely one base device 200a and two side devices 200b. The orthotic 100 will move relative to the central or base adjusting device 200a and it will return to an “open” position when the surface of the orthotic is unloaded.
-
- Correct spinal alignment;
- Maintenance alignment all night;
- Add on functionality;
- Sleep apnea splint attachment;
- Orthotic Audio speakers;
- Thoracic section to immobilize for cervical fractures/unstable cervical spines;
- Self adjusting height mechanism;
- Orthotic like structure;
- Attachment for CPAP, oral sleep apnea devices;
- Attachment for thoracic braces;
- Ability to be self adjusting or fully immobilize the cervical spine (such as when required for fractures or post surgery); and
- In built speakers.
The pillow orthotic is an answer to not only prescribing a desirable multi-positional pillow but will also assist with pain control and relief.
It is considered that a 3D and or multi axis device and a match of an oval head with a flat bed surface can address the above noted related art problems. The pillow orthotic of preferred embodiments does just this. It is an adjustable support device that may also allow for attachment of thoracic and facial devices such as CPAP, sleep apnea devices and thoracic immobilization braces.
Embodiments will use a small layer of memory foam 300 and a manual adjustment device 200.
It solves the issue of two planes by adjusting against a more rigid surface.
Due to the design of this product it also gives the option for some other additions which are unique. These being the ability to add on an attachment for complete immobilization, to allow for a pillow for those with neck fractures or post surgery for the neck; or for those using oral sleep apnea devices and CPAP machines.
The concept of a preferred embodiment is a pillow in the form of a orthotic like structure as described above which is a combination of solid and deformable products with a self adjusting height altering device. It is also innovative in its ability to have attachments to allow solutions to medical conditions and will also have entertainment features with the option for inbuilt speakers for auxiliary jack devices.
A person lies in the orthotic like device. The self adjusting heights will work with the head weight to self adjust to the persons required height in both the side and back sleeping position. When a person rolls and changes their position, the orthotic will roll with the person. The shoulder side of the pillow is cut out, as shown at 400 in
In another preferred embodiment, the present invention takes the form of a head and/or neck support comprising a shell that may be deformed by integral adjustable support means. The support in its most preferred form may be inserted into a pillow or cushion.
Referring to
Firstly the use of a frame comprising a shell like structure 100 set at an angle of 90° or greater than 90° and up to 180° between the middle portion 800 and the two outer wings 900 enables the accommodation of the different arcs of rotation about the central access to maintain a neutral spine position allowing for shoulder or back position. This device enables the smooth transition from supine to side.
Secondly manual prescription based adjusting straps 700 for adjustable support devices 200 enables the exact heights required for a sleep position to be set and calibrated to the user. There will be a minimum of 3 separate straps 700 (preferably comprising one first adjustable strap 700a located for the central portion 800 and two second 700b adjustable straps located at the wing portions 900 for deforming the adjustable integral support means 200. In this way, the unit has one or more areas or regions of height adjustment along the shell.
The sides/edges 500 (shown in
In the preferred embodiment each support strap 700 extends through respective opposed apertures or slots 850 which are formed in the outer peripheral edge portions of the sides 500.
With reference to
The opening provided by the volume defined by the shell 200 is covered with any sheet of foam, preferably memory foam with a contour to allow for comfort and support of all resting surfaces, to provide a layer 300 which is attached to itself on the rear surface 250. A cover 320, indicated in
The layer 300 also acts as a cushion between the person's neck and the support straps 700 thereby increasing the person's level of comfort. The layer 300 may be formed of suitable cushioning material. A protective cover 320 may also be provided for fitting over the shell to attach the outer foam layer and or other pillows to completely cover it. A conventional pillow cover can also be used over the top of the units cover. This cover may be resealed in any known manner, for example by way of Velcro™ or a zipper such that if another person wishes to use the head and neck support 100, it is a simple matter of opening the protective cover 320 to adjust the length of the support straps 700 to suit the new user and then reseal the protective cover 320. It is also envisaged that the layer 300 may be part of the protective cover 320 and may be removable with the protective cover 320 for cleaning. The rear surface 250 of the shell 200 may have a number of cut-out openings 240 (shown in
The lands 260 also provide a convenient means by which the shell 200 may be grasped, thereby providing a point of purchase which is of assistance when one is required to pull on a support strap 700 to shorten its length.
The land formed by a partial cut in the rear surface 250 creates a stabilising device 270. This device 270 ensures that despite the convexity of the rear surface 250 as shown in
The use of self adjusting stabilising bars allow for an inner frame/shell and supporting straps to remain horizontal to the support surface. These reinforced members work by remaining rigid whilst the frame/shell is tensioned. This creates an supporting wing. The stabilisation of this could also be achieved by a wedge unit which was trialled or a cut out depression on the outer foam to support or support from the foam itself.
The head and neck support 200 may be used as a removable support cushion to be placed against the flat surface of a resting device to provide better, or more appropriate, neck support in all planes.
