The human spine is generally comprised of thirty-three (33) vertebrae with a disc located between each neighboring pair of vertebrae. The center portion of each disc, the nucleus pulposus, is made of a watery, gelatinous material which is contained within a tough outer ring, the annulus. As humans age, starting in any given human's mid-twenties, the nucleus begins to lose some of its water content.
The accompanying drawings illustrate various examples of the principles described herein and are part of the specification. The illustrated examples are given merely for illustration, and do not limit the scope of the claims.
Throughout the drawings, identical reference numbers designate similar, but not necessarily identical, elements. The figures are not necessarily to scale, and the size of some parts may be exaggerated to more clearly illustrate the example shown. Moreover, the drawings provide examples and/or implementations consistent with the description; however, the description is not limited to the examples and/or implementations provided in the drawings.
The dehydration of discs within a human vertebra is a natural process though it can be accelerated by such things as trauma, weight, chronic posturing, and genetic predisposition. As the nucleus pulposus dehydrates, the discs become thinner and the vertebrae begin to sit closer together. As a result of the discs thinning with age, there are some anatomic changes that can create spine related pain. In an example, the diameter of the foraminal openings located bilaterally between each pair of vertebrae become narrower leaving less space for the exiting nerve roots. Should a nerve root branching off the spinal cord be compressed at the location wherein that nerve root is exiting its foraminal opening, there will be resultant radicular symptoms including pain, numbness, paresthesia, and/or loss of strength in the corresponding muscles. An additional symptom associated with the thinning of the discs is an increase in friction of the vertebral facet joints. These joints naturally slide on each other allowing certain movements and limiting others. An increase in friction between these joints, however, will cause irritation and pain in those joints.
Since re-hydration of discs is not plausible in an aging individual human, removing the compressive force from the nerve roots and facet joints is may be accomplished with correct positioning of the spine. Activities and positions that put the spine in an extended position (i.e. leaning backwards) will increase nerve and facet compression while activities and positions that put the spine in a position of flexion (i.e. leaning forward) will decompress these structures. Therefore, lying down in a flexed position unloads weight placed on the nerve roots and facet joints thereby alleviating acute discomfort and allowing for better sleep. Additionally, unloading these structures for prolonged periods, as in sleep, will allow them to heal thereby alleviating the possibility of permanent damage. This results in less irritation as a human goes about the human's daily activities many of which will include extension movements and extended positions.
Multiple attempts have been made to produce mattresses and sleep aids which place the aging body in an anatomically comfortable position. However, most of these attempts are made using foam, springs, and other materials which are heavy and cumbersome and do not lend themselves to easy transport in the case of backpacking and camping, for example. For example, the mechanical bed systems such as hospital beds are intended to support the human form in an ergonomically correct, comfortable position by allowing for incremental lifting of the head and torso and elevation of the knees in a manner. However, such beds are not conveniently portable. On the other hand, sleeping surfaces which are light weight and designed for relatively easy transport, such as in the backpacking and camping scenario, may, in fact, be made of light-weight foam. However, these surfaces, though they may differ in thickness and softness, are generally flat and do not support an aging spine ergonomically.
Although particular examples presented in the specification have been described, various modifications and changes may be made without departing from the spirit and scope of the present specification. The present specification may describe examples in other specific forms without departing from its structures, methods, or other characteristics as broadly described herein and claimed hereinafter. The described examples are to be considered in all respects examples and not restrictive conditions.
The present specification describes an inflatable sleep system. This inflatable sleep system may position a supine spine in a degree of flexion by wedging the head and torso of the user upward as well as elevating the knees. This may be done for a user having an aging supine spine or other type of spine discomfort resulting from the compressive forces places on the joints or nerves associated with the user's spine. Such position causes posterior tilt of the user's pelvis which creates lumbar and thoracic flexion thus decompressing the nerve roots and facet joints as described herein.
The present specification describes a sleeping system that includes a torso wedge section, the torso wedge section being inflatable; and a knee bolster section, the knee bolster section being inflatable.
The present specification also describes a positioning device that includes a torso wedge section to receive weight from a user's torso; a knee bolster section to receive weight from a user's legs; and a strap coupling the torso wedge section and the knee bolster section together to prevent the torso wedge section and the knee bolster section from separating.
The present specification further describes a sleeping system that includes an inflatable body, the inflatable body including a first section to support a torso of a user; a second section to support a leg of a user; a third section intervening the first and second sections to support a midsection of a user.
The present specification describes an inflatable, light-weight sleeping system that wedges the torso and bolsters the knees. This sleeping system is portable and may be constructed as a single unit or as a system comprised of two or more pieces.
When comprised of multiple sections, the sleeping system may include a wedged-shape torso wedge section that supports an upper head and torso section of a user and a knee bolster section that supports the legs of the user. The two-piece system described herein may or may not be used in conjunction with a flat inflatable or foam sleeping pad. When used with an existing flat pad, the flat pad is place on top of the sleeping system being described herein. When used without a separate flat pad, the two-piece system could be produced with a flat distal extension of both the wedge and the knee bolster so as to create padding under the hips and the lower legs accommodating for greater comfort in those areas. Whether used alone or in conjunction with a flat sleeping pad, the sleeping system supports the body in an ergonomically correct position while in a supine or in a side lying position. In the two-piece system, each of the sections may be separately inflatable and, as such, may also be adjustable to accommodate for individual body type and comfort. Accordingly, the two sections may be held together with adjustable straps, overlapping flaps with a hook-and-loop fastening material such as VELCRO® adhesion, other adjustable connecting devices so that their distance apart from each other can be changed so as to adapt to individual height and torso and leg length. VELCRO® is a registered trademark of Velcro BVBA.
In an example, the torso section is wedge shaped. The lumbar spine rests on the bottom of the wedge of the torso section with the thoracic spine, cervical spine, and head gradually being elevated. The height and incline of the wedge are adjustable with the amount of air forced into the interior cavity of the torso section.
The knee bolster section may be in the form of a half oval shape. The knee bolster section may be placed directly under the knees of a user when the sleeping system is in use. While lying in supine, the knee bolster section may allow for various levels of knee and subsequently hip flexion as it is also adjustable through inflation for individual comfort.
Whether being used in conjunction with a sleeping pad or by itself, the torso wedge section and knee bolster section when deflated may be rolled up with or without the pad as though they were a single unit. This may provide for quick, easy, and compact storage. In an example, both the torso wedge section and knee bolster section may have a thin sleeve on their top surfaces allowing for an accompanying sleeping pad to slide through and to be held in place thus creating a complete, ergonomically correct sleeping surface that can be used indoors or outdoors. In an example, both the torso wedge section and knee bolster section may have a secondary inflation surface on their top surfaces allowing for inflation of that secondary inflation surface. This secondary inflation surface may create a complete, ergonomically correct sleeping surface that can be used indoors or outdoors.
When constructed as a single unit, the inflatable sleeping system may also provide a degree of flexion by wedging the head and torso of the user upward as well as elevating the knees. In some examples, the inflatable sleeping system may extend the full length of the body and would create a contoured surface in which a first section of the pad used to support a user's torso is in the form of the torso wedge section thereby gradually elevating the head and torso. Additionally, a second portion of the inflatable sleeping system creates a bolster under the knees elevating them into a flexed position similar to the knee bolster section described herein. Intermediary to the first and second sections may be a third section that supports a user's midsection: parts of the user's body between the torso and the legs.
When constructed as a single unit, the inflatable sleeping system may include a single air valve for inflation of the sleeping system. In another example, the inflatable sleeping system may include a valve for both the first and second sections so that each section might be adjustable. As a single unit, the sleeping system may provide thermal protection from the surface upon which it is laid. The thermal protectivity of the sleeping system may be dependent upon the materials used in its construction and the thickness of the inflated sleeping system once inflated. Consequently, the inflatable sleeping system may be used indoors and/or outdoors and may be rolled or folded into a compact shape for easy storage and transport.
Ergonomically correct position during sleep or resting while backpacking and camping, for example, is beneficial to a user engaged in strenuous activity. However, the described sleeping system may be used in various other circumstances for similar purposes. Whether as a single unit or as a two-piece system and with or without an accompanying flat sleeping pad, the described sleeping system may be deployed on any flat indoor or outdoor solid surface. For example, the described sleeping system may be placed on top of a flat-bed mattress, sofa, flooring material, lawn, sandy beach, and truck bed, among other surfaces, while giving contour to the body's natural curves that such surfaces might not otherwise offer. Furthermore, if as a single unit it is constructed using thereto-protective materials or if as a two-piece system is constructed using thereto-protective materials or if used in conjunction with a flat sleeping pad constructed with thereto-protective materials, the sleeping system offers a soft, ergonomic contour as well as protection from non-temperate surfaces such as snow and ice. Flat sleeping pads that could be used in conjunction with the two-piece system might include those made of foam, those that are inflatable, and those that use a combination of inflatable air and solid material. The inflatable and non-inflatable pads may have a variety of different cell patterns and usually vary from 2.5 to 7.5 cm in thickness. The two-piece system will accommodate any of these types of sleeping pads that are 62 cm in width or smaller and of any length, though the width of the presently described sleeping system could be extended to allow for the possibility of interfacing with wider pads.
As seen in
As shown in
In an example, the top surfaces of the torso wedge section (105) and/or knee bolster section (110) may include a sleeve to help keep a flat sleeping pad in place. In this example, the sleeve may take the place or be formed on top of the torso section extension (130) and/or knee section extension (220). Accordingly,
As described herein, an additional pad may be draped over the sleeping system (100) to add more comfort to the use. Accordingly, in or to minimize slippage of the additional sleeping pad being used in conjunction with the inflatable sleeping system (100), a top surface of both the torso wedge section (105) and knee bolster section (110) may be covered with a silicone screen print in order to increase the friction between the pad and the sleeping system (100).
In order to maintain the form of the torso wedge section (105) and knee bolster section (110) while they are inflated and in use or over the lifetime of the sleeping system (100), a number of nylon strips (240) may be attached to the inside surfaces of the torso wedge section (105) and/or knee bolster section (110). In a specific example, the nylon strips (240) may be ultrasonically welded to a top and bottom panel of the torso wedge section (105) and/or knee bolster section (110). These nylon strips (240) may be 7 cm in width and of appropriate length to allow for correct tapering of the torso wedge section (105) and/or knee bolster section (110) as described herein. In an example, the torso wedge section (105) may have three columns of four interior nylon strips (240) and the knee bolster section (110) may have two outside columns of three nylon strips (240) and one center column of two nylon strips (240). Although specific examples are either shown or described in the present specification, these are meant merely as examples and the present specification contemplates the use of any number of nylon strips (240).
In an example, the torso wedge section (105) and knee bolster section (110) may have their own twist valve, plug valve, or air valve (245) for inflation/deflation of either of the torso wedge section (105) and/or the knee bolster section (110). In an example, the air valves (245) may be located in the headward ends, on the outer edges, and/or in the lower corners of each of the torso wedge section (105) and knee bolster section (110) as shown in
The inflatable sleeping system (100) may be manufactured to weigh between 0.4-0.6 kgs (12-20 oz). If rolled up with a pad, it may add no more than 5 cm (2 inches) to its storage circumference. If being stored by itself, the sleeping system (100) may be rolled up or folded into a small package.
In an example, the sleeping system (100) may be 200 cm long and be 60 cm in width, though these dimensions can be altered during fabrication to accommodate a specific size of a user (125). A first end (405) of the sleeping system (100), when fully inflated, may elevate 19 cm from the sleeping system's (100) level surface and taper downward for 80 cm toward the center of the sleeping system (100). The second section (410) associated with where a user places the user's legs and feet of the sleeping system (100) may also include a tapering upward from the sleeping system's (100) level surface to an apex of 12 cm when fully inflated and back down to a certain level of the sleeping system (100). The apex may be located 70 cm from the second end (415) of the knee bolster section (110) sleeping system (100) and would taper downward in either direction for 45 cm to the certain level of the sleeping system (100).
To help maintain the shape of the sleeping system (100), the sleeping system (100) may include a number of nylon strips (240) fastened to the inside surfaces of the walls of the one-piece sleeping system (100). The configuration of these nylon strips (240) in the one-piece sleeping system (100) would be very similar to that of the two-piece sleeping system (100).
In an example, the one-piece sleeping system (100) might have a single air valve (245) on a surface at the first end (405) of the sleeping system (100) (i.e., at the ground level). In another example, the one-piece sleeping system (100) might have two air valves (245) in which on valve is located at the ground level of first end (405) thereby controlling inflation of the upper half of the sleeping system (100) and a second air valve (245) located at the ground level of the second end (415) to control the lower half of the sleeping system (100). These air valves (245) may be inflated by mouth or with the use of a small battery operated or mechanical pump.
As a one-piece, non-insulated system, the sleeping system (100) may weigh between 0.4-0.6 kgs (12-20 oz). When folded up for storage or portage, the dimensions of the one-piece sleeping system (100) may be approximately 20 cm×30 cm×4 cm (8 in×12 in×1.5 in).
The specification and figures describe a body support described as a sleeping system (100) herein. The sleeping system (100) may provide an optimal resting position for a user with back pain or back problems. The sleeping system (100) may do this by decreasing nerve and facet compression as the sleeping system (100) placed the user's vertebra in a position of flexion. This increases the longevity of pain-free articulation of the user's vertebra during daily activities. Because the sleeping system (100) is inflatable, it may be used anywhere with the ability to easily transport it from location to location. Still further, additional pads may be added to the sleeping system (100) for additional user comfort.
The preceding description has been presented to illustrate and describe examples of the principles described. This description is not intended to be exhaustive or to limit these principles to any precise form disclosed. Many modifications and variations are possible in light of the above teaching.
