This invention relates to the prevention or cure of heel sores for bed patients. The product is a medical boot, referred to as the “HeelCheck Boot,” 1 which utilizes a unique combination of angled foam and fiber. The HeelCheck Boot 1 includes several other features that enhance the healing and prevention of heel sores while ensuring no other medical problems are created for the patient.
Heretofore several different foot and leg devices have been proposed for the cure or prevention of heel sores. These sores are known more specifically as decubitus ulcers, and generally form by frictional irritation between the heel of a bed ridden patient and the bed linens or mattress. Lying in a particular position for a prolonged period produces external pressures on skin and tissues covering rigid or bony body parts, such as the heel. This pressure compromises the blood supply to those rigid or bony areas which, after a sustained period, results in “bed sores.”

U.S. Pat. No. 5,367,789 is a protective medical boot and orthotic splint—a soft medical boot with splint bar for adjusting angle of the foot. The device comprises a rigid insole, rigid splint bar, hinge internal sac filled with air/water/gel, and a rubberized laminated sole.
U.S. Pat. No. 5,449,339 Heel supporting protective boot for bed patients—foam with foot and leg supporting portions. The invention features friction reducing material and extra padding composed of foam, serving to limit foot drop.
U.S. Pat No. 8,834,396; 16 Sep. 2014; A heel supporting and protective boot for bed-ridden patients, comprising unitary exterior and interior body forms having fiber filling and an angled foam wedge. Sewn tube holes on both sides allow for insertion of medical tubing. The inner fabric of the boot is antibacterial and moisture absorbent, while the outer fabric is moisture repellant. Left and right “Y-straps” provide secure upper and lower fastening. An arc-type opening at the heel of the bottom section of the boot and a circular cutout in the foam wedge allow a patient's heel to overhang freely exposed to air, provide proper elevation, and enhance blood circulation.
The foregoing objects and advantages of the present invention are accomplished in illustrated embodiments disclosed herein, which embodiments comprise a new and improved heel-supporting protective boot for bed-ridden patients. The boot, referred to as the “HeelCheck” boot 1, has a unique combination of foam and fiber materials fabricated within five interconnected sections of the HeelCheck boot 1.
In essence, the HeelCheck Boot 1 comprises a unitary, foldable body form further comprising five individually-stitched sections, or pockets, each filled with either fiber or foam. The pockets are formed by custom stitches which form seams, joining an inner fabric 5 and an outer fabric 4. The five sections consist of a left sidewall 10 further containing an upper and a lower tube-hole 14, 15, a right sidewall 20 also containing an upper and a lower tube-hole 25, 26, a rectangular bottom section 33 having a heel arc 32 at one end, an inner flap 23, and an outer flap 13. A continuous, one-piece outer fabric 4 and a continuous, one-piece inner fabric 5, and a sloped foam wedge 40 contribute to the functional qualities of the five sections.
Of the above five sections, the inner flap 23 manifests a foam 3 filling, and the bottom section 33 contains a sloped, rectangular foam wedge 40 which foam wedge 40 is further enveloped with a surrounding quantity of fiber 2 fill. The remaining three sections are filled entirely with fiber fill 2. Individual stitching 8 is performed at specific, corresponding locations in the unfolded body forms of both the outer fabric 4 and the inner fabric 5, thereby resulting in the above-described sections, or pockets of the HeelCheck Boot 1. All five sections, in functional use, are folded into a shape resembling the contours of the human foot, and a series of cross-straps and Y-shaped straps and appropriate connecting means serve to maintain the HeelCheck Boot 1 securely about the foot 51 of a patient.
It is a primary objective of the present inventive concept to provide a new and improved heel boot for bed-ridden patients which eliminates many of the disadvantages and problems encountered with prior art medical boots.
It is another object of the present inventive concept is to design a new and improved heel supporting boot with the features herein described which is especially useful in the prevention or cure of bed sores on the heel.
Another objective of the HeelCheck Boot 1 is to eliminate friction and pressure contact between a patient's heel and the bedding surface.
A further object of the inventive concept to provide an improved method of elevating a patient's the heel without hyper-extending the knee. Adequate elevation also facilitates the exposure of the heel to a continuous circulation of air.
Another objective of the inventive concept is to provide sewn tube holes in the left and right sidewalls of the HeelCheck Boot 1 so that a sequential compression pump or other necessary medical tubing can be used 1 with the boot.
An important object of the inventive concept is to utilize the cushioning effect of a combination of fiber filling and an angled foam wedge to facilitate the healing and/or prevention of decubitis ulcers of the heel.
Another objective of the HeelCheck Boot 1 is to furnish to hospitals and caregivers a new medical boot that does not allow bacteria to grow inside the boot.
A further object of the inventive concept is to construct a product that utilizes moisture absorbing fabric on the interior surfaces of the medical boot and additionally, provide a moisture repelling fabric on the exterior surfaces of the boot.
An important objective of the inventive concept is to provide a new method of secure and effective strapping for the purpose of eliminating the possibility of “foot drop” of bed-ridden patients.
A further objective of the inventive concept is to utilize a material that will ensure necessary air ventilation and minimize internal heat buildup.
Another objective of the inventive concept is to utilize a horizontally flat design shape of the foam wedge, to effectively inhibit internal or external rotation of the patient's lower leg, thus avoiding knee and hip joint problems.
An important objective of this inventive concept is to ensure ease of operation of the HeelCheck Boot 1 for the caregiver with respect to both fitting the boot onto a patient as well as removing the boot.
Another objective of the HeelCheck Boot 1 is to construct it so as to effectively eliminate inadvertent disengagement of the patient's foot.
A further object of the inventive concept is to provide an improved boot that does not soil due to patient incontinence.
Another objective of the inventive concept is to ensure that there are no pressure points created within the HeelCheck Boot 1 while at the same time, maintaining adequate elevation of the patient's heel.
Another objective of the inventive concept is to provide a stable, durable boot that ensures effective healing care for patients regardless of their size or weight.
An important objective of the inventive concept is to provide a medical boot which is economical to manufacture and simple to utilize by nursing personnel while accomplishing a multitude of healing goals.
For a better understanding of the invention, reference will be made to the following detailed description taken in conjunction with the drawings, in which:
The objects, features, and advantages of the concept presented in this application are more readily understood when referring to the accompanying drawings. The drawings, totaling nine figures, show the basic components of the HeelCheck Boot 1 and the manner in which this inventive concept is used. In the several figures, like reference numbers are used in each figure to correspond to the same component as may be depicted in other figures.
Referring now more particularly to the drawings herein, and beginning with
The upper and lower cross-straps 30, 31 must normally be unfastened in order to separate the left and right inner sidewalls 60, 61, thereby allowing insertion of a patient's foot. The bottom of the patient's foot will be proximate to, or abut the inner flap 23, when the foot is fully inserted. The bottom section 33 of the HeelCheck Boot 1 contains a foam wedge 40 (out of view) and is topped by the inner surface 62. A pocket formed by the left outer sidewall 10 and left inner sidewall 60, and a pocket formed by the right inner sidewall 61 and right outer sidewall 20 are each filled with a pliable fibrous material, referred to as “fiber fill” 2. Likewise, a pocket, or section formed by the inner flap 23 also contains fiber fill 2. A section pocket formed by the bottom inner surface 62 and bottom outer surface 63 houses the foam wedge 40, along with a quantity of fiber fill 2 on the top surface of the foam wedge 40.
In the preferred embodiment, the outer surfaces of the HeelCheck Boot 1 comprise a “rip stop” type outer fabric 4, a woven, nylon-threaded material which is generally water resistant. In the preferred embodiment, the inner surfaces of the HeelCheck Boot 1 are fabricated with an inner fabric 5 which may comprise brushed, micro-suede, or similar material that is treated to exhibit anti-bacterial properties. The inner fabric 5 and the outer fabric 4 are shaped into compatible “body forms” and are combined as the result of continuously-stitched 8 junctions, or seams, as illustrated in various locations in the drawing figures.

The two pairs of tube holes, 14, 15, and 25, 26 may often be required for the insertion of medical tubing. The primary medical tubing that would typically be used in conjunction with a pressure relief medical boot would be a sequential compression pump. Many patients that would require a rehabilitative medical boot, as disclosed herein would probably also need the use of medical tubing. Thus, the left upper and lower tube holes 15, 14, and the right upper and lower tube holes 25, 26 allow for the use of said tubing while still taking advantage of the pressure relief characteristics of the HeelCheck Boot 1.
Also, as visible in
Referring to
It can be seen that, in functional use of the HeelCheck Boot 1, a patient's lower leg 50 would rest against the bottom inner surface 62 (which forms the upper surface of a pocket containing the foam wedge 40 and an amount of fiber fill 2). Further, the patient's heel 52 would be protruding into the heel arc 32 opening, which serves effectively as a direct means of preventing a heel sore during the time a patient is bedridden. The upper cross-strap 30 and the lower cross-strap 31 serve to retain the patient's lower leg 50 properly within the confines of the Heel Check Boot 1. The bottom of the patient's foot 51 would rest against the inner flap 23, which inner flap 23 would be held in a secure closed position by means of the outer flap 13 securing the inner flap 23 in position.

The profile view of the foam wedge 40 as shown in
The elevation of a patient's foot 51 and clearance of the heel 52 over the circular cutout 44 of the foam wedge 40 helps prevent bed sores, in particular, decubitus of the heel. Blood circulation in the foot 51 is also enhanced. The HeelCheck Boot 1 is constructed of a flat base 47, and of sufficient width, so as to enhance horizontal stability of the HeelCheck Boot 1. The width of the base 47 of the HeelCheck Boot 1 is of a dimension that ensures internal and external rotation of the lower leg 50 is limited. The length of the foam wedge 40 extends from the patient's mid-calf to just above the ankle at the ridge 49 of the foam wedge 40, as illustrated in
It is to be noted that the fiber fill 2 of the HeelCheck Boot 1 comprises any of several materials that provide a soft, pliable, medium-dense texture. The angled or sloped top 41 of the foam wedge 40 is utilized to ensure the patient's heel 52 remains comfortably elevated and exposed to air without hyper-extending the knee joint. By elevating the heel 52, combined with a circular cutout 44, which allows suspension of the heel 52 itself, pressure is offloaded from the heel 52, not just reduced.
The combination of fiber fill 2 and the foam wedge 40 works effectively together to eliminate or significantly reduce any pressure points created by the use of a foam component alone. The foam/fiber combination extends under the ankle and terminates at a point above the patient's heel 52 so the HeelCheck 1 boot is prevented from making direct contact with the patient's heel 52. The HeelCheck 1 boot is constructed with left outer and inner sidewalls 10, 60 and right outer and inner sidewalls 20, 61 designed to support the patient's lower leg and ankle.
The leg support fiber/foam portion extends between the inner and outer sidewalls 10, 60, 20, 61 so as to support the patient's lower leg with the heel elevated well above and out of contact with any bedding or mattress. The heel 52 is completely elevated and thus exposed to air circulation by means of the circular cutout 44.
The boot additionally uses dual types of material for its outer fabric 4 and inner fabric 5 covering. The outer fabric 4 repels any fluid that may come into contact with the HeelCheck 1 boot. An inner fabric 5, which may comprise a brushed micro-suede material, absorbs fluids, including a patient's perspiration, and also is antibacterial.
The disclosed boot is fabricated with left and right “Y-straps” 16, 17, 27, 28 that provide secure upper and lower fastening of the HeelCheck 1 boot as it envelops the patient's foot 51 and lower leg 50. Finally, the HeelCheck 1 boot also uses upper and lower “cross-straps” 30, 31 which keep the patient's foot 51 at a 90 degree angle relative to the lower leg 50 and help eliminate foot drop. By eliminating foot drop, essential blood flow is enhanced and heel cord tightening is eliminated. A 90 degree angle, as measured between the plane of the sole of a patient's foot 51 and his/her lower leg 50 is the optimum foot orientation which allows adequate blood circulation.
