Description
BACKGROUND

This version of the invention is concerned with the field of therapeutic cooling devices. More specifically, this version of the invention is concerned with a movable and adjustable stand that houses an aircast cooler in proximity to an aircast worn by a user in order to provide the aircast with a continuous supply of cooling solution.

PRIOR ART

People who are recovering from various injuries, such as broken or fractured bones, trauma, tears, or sprains to muscles and other tissue, use an aircast to support the injured body area to aid in healing of the damaged body part. A typical aircast is wrapped around the damaged body part and is inflated to a specific pressure to provide resistance against the damaged body part as an aid in healing, such as ensuring proper alignment of a broken or fractured bone or to support damaged tissue and control swelling and inflammation. The aircast also contains means whereby a cooling solution can be introduced into the interior of the aircast and circulated throughout channels, pockets, or bladders in the aircast so as to provide cold and compression therapy. This type of therapy is crucial in treating damaged, sprained, stressed, or inflamed tissue. The cooling solution is typically ice water, and such solution is stored within an aircast cooler, jug, or similar storage device. A typical aircast cooler is comprised of an insulted, cylindrical container enclosing a storage cavity, lid or cover releasably attached to the container over a top aperture thereof, grasping handle connected to the container, and a flexible tube or hose of varying length. The flexible tube is attached at a first end at or near the bottom of the container and at a second end to the aircast cooler. The aircast cooler may have a control valve or spigot that releases cooling solution from the container to the flexible tube.

When the flexible tube is connected to the container and the aircast, cooling solution is transported from the container, through the tube, and into the aircast. The cooling solution, maintained in the aircast and directly over the injured body part, provides the necessary application of cold and compression therapy to enhance healing.

Although the use an aircast cooler to deliver cooling solution to an aircast provides a therapeutic effect, several disadvantages and drawbacks result from such an arrangement. For instance, if the user desires to move about while the aircast cooler is connected to the aircast, the user must physically transport the aircast cooler, such as carrying the cooler by the handle. This option for the most part is infeasible as the aircast cooler, filled with cooling solution, presents significant weight and bulk and cannot be transported or carried by a user nursing a damaged body part. Alternately, the user can enlist the aid of another person to hold or carry the aircast cooler, who may not always be available or agreeable for such a task. The user could also fashion or use various makeshift support and transport devices, such wheeled carts, dollies, and the like. However, such devices do not support the aircast cooler at the proper height in relation to the aircast, which is necessary to ensure adequate and uninterrupted flow of cooling solution, nor do such devices provide the stability necessary to prevent the aircast cooler from being toppled or turned over in the case if the aircast or flexible tube is suddenly impacted.

What is needed then to overcome the aforementioned disadvantages of storing or supporting an aircast cooler while said cooler is connected to an aircast is the provision of a movable and adjustable stand for aircast cooler. Such a cooler stand would support an aircast cooler above a floor, ground, or support surface and contain means to allow the stand to be moved about over the floor, ground, or support surface without being toppled or tipped over during use, and to be adjusted in height so that the aircast cooler can be aligned in the most optimum position with respect to an aircast while the aircast cooler is connected thereto.

DISCUSSION OF THE PRIOR ART

Numerous devices for supporting therapeutic and medical apparatuses in close proximity to a user or patient have been provided in the prior art. Even though these devices may be suitable for the specific individual purposes to which they address, they would not be suitable for the purposes of the present version of the invention, as such devices are generally intended to support an apparatus, such as a container for intravenous solution, connected to a patient who is generally immobile or stationary. These devices are exemplified by U.S. Pat. No. 4,541,596, Portable Intravenous Pole For Use In An Emergency, issued to Price on 17 Sep. 1985; U.S. Pat. No. 4,744,536, Collapsible Pole And Stand Combination, issued to Bancalari on 17 May 1988; U.S. Pat. No. 5,344,169, Multi-Pole Support Stand, issued to Pryor et al. 6 Sep. 1994; and U.S. Pat. No. 6,182,662, Intravenous Transport/Support Device, issued to McGhee on 6 Feb. 2001.

As such, it may be appreciated that there is a continuing need for a new and improved stand for storing and supporting an aircast cooler in proximity to a user or patient wearing an aircast while said aircast cooler is connected to said aircast. Such an aircast cooler stand will support the aircast cooler at a height and position that optimizes the flow of cooling solution from the cooler to the aircast and provide the optimum stability the prevents the stand and aircast cooler from being toppled in the case of a sudden impact impinging upon the flexible hose or stand while ensuring that the flexible hose does not become disconnected from the aircast and aircast cooler. In these respects, the present version of the invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus that substantially fulfills this need. Additionally, the prior patents and commercial techniques do not suggest the present inventive combination of component elements arranged and configured as disclosed herein.

The present invention achieves its intended purposes, objects, and advantages through a new, useful and unobvious combination of method steps and component elements, with the use of a minimum number of functioning parts, at a reasonable cost to manufacture, and by employing only readily available materials.

SUMMARY

The present version of the invention, which will be described in greater detail hereinafter, relates to the field of therapeutic cooling devices. More specifically, this version of the invention is concerned with a movable and adjustable stand that houses an aircast cooler in proximity to an aircast worn by a user in order to provide the aircast with a continuous supply of cooling solution. My version of the invention overcomes all of the shortcomings listed previously, in addition to novel aspects that will be described in detail hereinafter.

Described briefly, according to a typical embodiment, the invention presents an adjustable and movable stand for aircast cooler. The stand supports an aircast cooler containing cooling solution above a floor, ground, or support surface so that the cooling solution contained within the cooler can be delivered to an aircast being worn by a user or patient in need of cold and compression therapy. The stand can be adjusted in height to align the aircast cooler so as to provide the optimum height or alignment of the aircast cooler with respect to the aircast or patient and can be moved about over a floor, ground, or support surface should a user or patient desire to be ambulatory.

The stand is comprised of a cylindrical container and a pedestal, said container attached to the top end of the pedestal. The container, which has an open top and encloses an interior space or cavity, is further comprised of a continuous lateral sidewall and a disc-shaped bottom sidewall. The lateral sidewall is surrounded by a first band located at the top edge of the lateral sidewall and by a second band located at the medial section of the lateral sidewall. The lateral sidewall is bisected into first and second sidewall members, and the bands are bisected into two band sections. The sidewall members are attached to each other at cooperating edges by hinges located on adjoining ends of the band sections. The first sidewall, hingedly attached to the second sidewall member, can be pivoted upon said hinges with respect to the second sidewall member, which remains attached to the bottom sidewall. An aperture is located within the first sidewall member proximate to the junction of the first sidewall member of the lateral sidewall and bottom sidewall.

The pedestal is comprised of an upright tubular assembly and a base. The tubular assembly is further comprised of a lower tubular member, locking collar, and upper tubular member with the upper tubular member telescopically engaged within the lower tubular member and maintained in position within said lower tubular member by the locking collar. The bottom sidewall of the container at the bottom surface thereof is attached to the top end of the upper tubular member. The base consists of a central hub, which is attached to the lower end of the lower tubular member and two cross members, said cross members disposed in perpendicular relation to each other. Wheels are located within the underside of the cross members at opposed ends thereof.

During use of the stand, an aircast cooler is situated within the container of the stand, resting upon the bottom sidewall of the container and surrounded by the lateral sidewall. The flexible tube of the aircast cooler is passed through the aperture of the first sidewall member of the container and extends for some distance therefrom to connection with an aircast. As necessary, the height of the container and aircast cooler positioned therein can be adjusted with respect to a floor, ground, or support surface and an aircast to which the cooler is connected by extending or retracting the upper tubular member within the lower tubular member and securing the upper tubular member in place by means of the locking collar. Additionally, the stand can be positioned at various locations upon a floor, ground, or support surface by wheeling the stand upon the wheels of the base.

The cooler stand can be customized or adapted with various accessories. For instance, the height of the lateral sidewall of the container can be increased by use of a second sidewall, which is inserted within the lateral sidewall. The second or extensible sidewall engages the lateral sidewall in slight frictional engagement and can be raised or lowered as necessary to accommodate aircast coolers of varying size and capacity. Similarly, an aircast cooler can be secured in place within the container and prevented from moving or being relocated within the container by inserting one or more flexible, resilient pads within the container between the inside surface of the lateral sidewall and cooler. To aid the base in supporting the tubular assembly and container in upright alignment, an outrigger stand can be detachable positioned upon the lower tubular member. The outrigger stand is comprised of a central collar, which receives the lower tubular member, four leg members pivotally attached to the collar, and four foot members, each of which is pivotally attached to a cooperating leg member. The foot members extend beyond the cross members and make contact with a floor, ground, or support surface so that the outrigger stand can augment the base in stabilizing the cooler stand. A sensor with audible and visual alarm is attached to tubular assembly to signal a user should the cooler stand deviate from the upright or optimum position.

A swivel hinge on one side thereof is attached to the top of the upper tubular member and on a second side thereof to the bottom surface of the bottom sidewall of the container. As such, the container will rotate with respect to the pedestal to re-orient the container and aircast cooler stored therein if the aircast, connected to the cooler, varies its position so that the aircast cooler and flexible tube remain properly aligned with the aircast. Additionally, alignment of the flexible tube can be adjusted, varied, re-oriented, or secured in place with use of a tube support arm. The tube support arm consists of a first collar detachably secured around the upper tubular member, first arm, second arm, and second collar. The first arm is pivotally attached at a first end to the first collar and at a second end to a first end of the second arm. The second arm at a second end thereof is attached to the second collar. As such, the first and second arms, and second collars can be pivoted with respect to each other and the first collar secured to the upper tubular member. The flexible tube extending from the aircast cooler is disposed within the second collar, which maintains the flexible tube a position necessary to facilitate delivery of cooling solution from the aircast cooler through the flexible tube to the aircast.

My invention, therefore, resides not in any one of these features per se, but rather in the particular combination of all of them herein disclosed. It is distinguished from the prior art in this particular combination of all of its structures for the functions specified.

In order that the detailed description of the invention may be better understood and that the present contribution to the art can be more fully appreciated, additional features of the invention will be described hereinafter.

An aperture 42 is located within the container 12, specifically within the first sidewall member 22 of the lateral sidewall 16 at the junction of the first sidewall member 22 and the bottom sidewall 18. The container 12 receives in the cavity 20 thereof and aircast cooler jug, and the tube of the jug, which is attached to an aircast, extends through the aperture 42.

Referring again to FIG. 1, the pedestal 12 is comprised of an upright tubular assembly 44 and a base 46. The tubular assembly 44 is further comprised of a lower tubular member 48, a upper tubular member 50, and a locking collar 54. The lower tubular member 48 and upper tubular member 50 are telescopically engaged with the upper tubular member 50 received within the lower tubular member 48. As such, the upper tubular member 50 can be extended or retracted with respect to the lower tubular member 48. The container 12, attached at the bottom sidewall 18 thereof to the top end of the upper tubular member 50, is thus raised or lowered in response to extension or retraction of the upper tubular member 50. The locking collar 52 is comprised of a tubular member 54 and a rotatable handle 56. The tubular member 54 is attached to the top end of the lower tubular member 48 and receives the lower end of the upper tubular member 50 as said tubular member 50 is extended from or retracted into the lower tubular member 48. The rotatable handle 56 is connected to a pin or similar device that makes contact with the lower tubular member 50 as the handle 56 is rotated in a particular direction, locking said tubular member 50 in place with respect to the lower tubular member 48 once said tubular member 50 and container 12 are adjusted to an appropriate height above a floor, ground, or support surface.

The base 46, attached medially to the bottom end of the lower tubular member 48, is comprised of a central hub 68 and two cross members 60, 62, which are disposed in perpendicular relation to each other 60, 62. Wheels 64 are located within the undersides of the cross members 60, 62 at opposed ends thereof.

Referring to FIG. 3, therein illustrated is the movable and adjustable stand for aircast cooler 10 showing the rear side thereof. The second sidewall member 24 is pivoted open upon hinges 38, 40 and away from the first sidewall member 22, which remains attached to the bottom sidewall 18, to reveal the interior of the container 12. Second band sections 32, 36, which are connected to the second sidewall member 24, are also separated from first band sections 30, 34, which are connected to the first sidewall member 22, respectively. The bottom sidewall 18 is fully exposed and accessible as necessary to position an aircast cooler jug within the container 12 upon the bottom sidewall 18.

A typical aircast cooler jug 66 is illustrated in FIG. 4. The jug 66 is comprised of a hollow, cylindrical container 68, detachable lid 70, and handle 72 pivotally attached to the top side of the container 68. A collar 74 is located on the container proximate to the bottom end thereof and surrounds a flexible hose 76 extending from said collar and contiguous section of container 68. The flexible hose 76 is hollow and transports coolant solution, typically ice water stored within the container 68, from the container 68 to an aircast (not shown) worn by a patient. As illustrated in FIG. 5, the aircast cooler jug 66 is situated within the cavity 20 of the container 12. More specifically, the container 68 of the jug 66 is resting upon the bottom sidewall 18 and is enclosed by the lateral sidewall 16. The flexible hose 76 extends from the container 68 of the jug 66 through the aperture 42 of the first sidewall member 22 of the cooler container 12. As such, stand 10 supports the jug 66 above a floor, ground, or support surface while the free end of the hose 76, extending from the container 68 of the jug 66 at a first end thereof, can be attached to an aircast (not shown) at a second, free end thereof. Cooling solution stored within the container 68 of the jug will be transported by force of gravity from the container 68 of the jug 66 through the flexible hose 76 and ultimately to the aircast to provide simultaneous cold and compression therapy to the skin, muscles, and other tissue encased within the aircast.

The aircast cooler stand 10 can be modified or customized with various accessories or devices to enhance and improve its functionality in a various applications. In FIG. 6, for instance, the aircast cooler stand 10 is illustrated with an extensible sidewall 78 aligned for insertion into the container 12 of the stand 10 so that the exterior sidewall is located adjacent to and enclosed by the lateral sidewall 16. The extensible sidewall 78 is a circular and continuous in shape so as to conform to the shape of the lateral sidewall 16. An indentation 80 is located along the bottom edge of the extensible sidewall 78 and is aligned with the aperture of the lateral sidewall 16 of the container 12 when the extensible sidewall 78 is inserted therein. As illustrated in FIG. 7, the extensible sidewall 78 is inserted within the lateral sidewall 16 of the container 12 with the top edge of the extensible sidewall 78 extending above the top edge of the lateral sidewall 16. The extensible sidewall 78 can be raised or lowered with respect to the lateral sidewall 16 so as to increase the holding capacity of the container 12 as necessary to accommodate cooler jugs of varying size and capacity. The outer surface of the extensible sidewall 78 makes slight frictional engagement with the inner surface of the lateral sidewall 16 as necessary to maintain the extensible sidewall 78 in position against the lateral sidewall 16 when the extensible sidewall 78 is raised or lowered as needed. When the extensible sidewall 78 is lowered within the container 12 against the lateral sidewall 16 thereof, the indentation 80 aligns with the aperture 42 in order to permit the flexible tube 76 of the container jug 66 to extend out and from the container 12.

In FIG. 8, therein is illustrated a series of flexible, resilient pads 82, 84, 86, 88. The pads 82, 84, 86, 88 are comprised of compressible, resilient material, such as rubber, foam, and the like and are inserted into the container 12 of a cooler stand 10 to occupy any space that may exist between the exterior surface of the container of the cooler jug and inner surface of the lateral sidewall 16 of the container 12 in order to prevent the cooler jug from becoming displaced from an optimum or initial position within the container 12. The pads 82, 84, 86, 88, when configured as illustrated, form a central space or area that can be occupied by a cooler jug. As displayed in FIG. 9, the pads 82, 84, 86, 88 are inserted into the container 12 of the stand 10 with the exterior sides of the pads 82, 84, 86, 88 making contact with the inner surface of the lateral sidewall 16 of the container 12. The central or inner space formed by the pads 82, 84, 86, 88 can be occupied by a cooler jug, and any space between the cooler jug and inner surface of the lateral sidewall 16 of the container 12 is taken up by the pads 82, 84, 86, 88. In this manner, the cooler jug can be prevented from sliding, moving, or otherwise being displaced from its original or optimal position within the container 12.

In FIG. 10, the cooler stand 10 is illustrated with an outrigger stand 90 releasably attached to the lower tubular member 48. The outrigger stand 90 can be fitted temporarily or permanently to the cooler stand 10 to improve the stability of the cooler stand 10 as necessary. Additional stability for the cooler stand 10 may be required, for instance, when the upper tubular member 50 is fully extended from the lower tubular member 48, when the capacity of the cooler jug positioned within the container 12 is larger than normal, or when the environment in which the cooler stand 10 is being used may subject the cooler stand 10 to conditions that may reduce or otherwise negatively affect the stability of the cooler stand 10. The outrigger stand 90 is comprised of a central collar 92 that is positioned around the lower tubular member 48, four narrow, elongate legs 94 that extend from the central collar 92 approximately every 90 degrees of arc, and footpads 96. Each leg 94 is pivotally attached at a first end to a cooperating hinge on the collar 92 and pivotally attached at a second end to a cooperating hinge on a respective footpad. In this manner, the legs 94 can be individually raised or lowered with respect to the collar 92, and each footpad 96 can be pivoted upon a leg 94 to conform to a floor, ground, or support surface.

In FIG. 11, the cooler stand 10 is fitted on the lower tubular member 48 of the pedestal 14 thereof with a motion sensor and alarm 102. The sensor 102 detects and notifies by alarm signals a user of any movement or motion that could cause the cooler stand 10 to tip over and fall. The motion sensor and alarm 102 is comprised in part of an exterior housing that contains motion sensing circuitry and power source well known in prior art and design, a visual alarm 106, such as a blinking light source, and an audible alarm 108, such as a buzzer, ringer, or the like.

In certain applications, it becomes necessary to reposition or reorient the cooler jug 66 or flexible tube 76 so that the flexible tube 76 can accommodate the location, position, or attitude of the user wearing an aircast, to which the flexible tube is attached. In some cases, the cooler jug 66 can be repositioned by moving the cooler stand 10 upon the wheels 64, or the upper tubular member 50 can be extended or retracted within the lower tubular member 48, as described previously. In some situations, however, it may be difficult or impossible to relocate the cooler stand 10 upon its wheels 64 or adjust the height of the tubular assembly 44 because of cramped quarters, intervening furniture, clutter, and the like. One alternative to relocating or moving the entire cooler stand 10 is to rotate or reorient the container 12 so that the direction and orientation of the flexible tube 76 can be re-aligned. As shown in FIG. 12, a rotatable or swivel hinge 110 (shown in phantom line) is attached on a first side thereof to the top of the upper tubular member 50 and on an opposed second side to the bottom side of the bottom sidewall 18. As such, the container 12 can be rotated with respect to the pedestal 14 as shown by directional arrows. The swivel hinge 110, illustrated in more detail in FIG. 13, is comprised of a ring-shaped outer band 112 and a disc-shaped inner hub 114. A series of ball bearings 116 is located partially within the outer edge of the of the hub 114 and inner edge of the outer band 112, thereby permitting the outer band 112 to rotate with respect to the hub 114. The swivel hinge 110 is thus secured to the cooler stand 10 by means of the outer band 112 attached at a first side thereof to the bottom side of the bottom sidewall 18 and the hub 114 attached to an opposed second side thereof to the top of the upper tubular member 50.

Referring to FIG. 14, therein illustrated is the aircast cooler stand 10 with a tube support arm 118 releasably attached to the upper tubular member 50 between the bottom sidewall 18 and collar 52. The tube support arm 118 is comprised of a first collar 120, first arm 122, second arm 124, and second collar 126. The first arm at a first end thereof is pivotally attached to the first collar 120 at hinge 128 and at an opposed second end pivotally attached to a first end of the second arm 124 at hinge 130. The second arm 124 at a second end opposed to the first attached to the second collar 126 at hinge 132. The second collar 126 as illustrated contains the free end of the flexible tube 76. In this manner, the second collar and cooperating end of the flexible tube 76 can be retracted to and from the upper tubular member 50 and container 12 and can be raised or lowered with respect to the upper tubular member and container 12. The tube support arm 118 thus functions to maintain the end of the flexible tube 76 in various positions as necessary to ensure the continued and uninterrupted flow of cooling solution from the cooler 66 to the aircast (not shown).

Referring to FIG. 15 in an alternative embodiment of the present invention, cylindrical container 12 can be removable attached to pedestal 14. Referring to FIGS. 16, 17, 18, and 19 there is depicted an enlarged view of the connection between the cylindrical container 12 and pedestal 14. The bottom side of cylindrical container 12 is adapted with adapted with a shaft 200 which extends linearly downward therefrom. The upper end 210 of pedestal 14 is hollow therethrough thereby allowing for the insertion of shaft 200 therein. Locking mechanism 56 secures shaft 200 in place locking mechanism further includes bore 202 and pin 220. As depicted, at a predetermined location, bore 225 extends horizontally through shaft 200. Bore 225 is adapted with threads to secure pin 220 in place. On opposing sides of the upper end 210 of pedestal 14 are apertures aligned with bore 225. Pin 220 is adapted with a release mechanism 221 for the removal of pin 220 from aperture 202.

The removal of cylindrical container 12 from pedestal 14 allows the stand to be used interchangeable for other uses. In the alternative embodiment the base of an Intravenous (IV) (not shown) stand can be adapted with shaft 200 thereby allowing for the insertion and removal of the IV into the upper end of 210 of pedestal 14.
