In an amputation surgery, a distal portion of a patient's limb or other extremity is removed. The remaining portion of the limb is referred to as an amputation stump. The procedure typically results in one or more surgical wounds (e.g., suture lines) on the stump. The surgical wounds may be positioned at a distal end of the stump, may extend around the stump, may extend along stump from the distal end towards the patient's torso, or some combination thereof. Proper and timely healing of these surgical wounds expedites prosthetic fitting and reduces the risk of complications such as tissue necrosis and re-amputation.
Amputation may also create a risk of stump oedema (i.e., fluid buildup in the stump) as the body adjusts the flow of bodily fluids to adapt to the loss of the portion of the limb, which may lead to further wounds due to deterioration of tissue (e.g., venous ulcer). Applying a compressive force to the stump may resist swelling of the stump and help prevent oedema and related complications.
Patient care may therefore be improved by an amputation dressing that facilitates healing of one or more surgical wounds at an amputation stump while also resisting swelling of the stump.
One implementation of the present disclosure is an amputation dressing. The amputation dressing includes a wound contact layer that includes a central panel and three or more petals extending radially from the central panel. The wound contact layer also includes a tube of elastic material twisted to form a point. The point is located substantially centrally along a length of the tube. The tube of elastic material is coupled to the central panel proximate the point. The tube is rolled from a first end of the tube to the point to form a first roll and from a second end of the tube to the point to form a second roll.
In some embodiments, the three or more petals comprise six petals spaced equidistantly around the central panel. In some embodiments, the wound contact layer is flower-shaped. In some embodiments, the central panel is positionable abutting a distal end of a stump, the three or more petals are positionable abutting sides of the stump, and an absorbent pad is aligned with the central panel. The first roll is unrollable to cover the wound contact layer, the absorbent pad, and the stump with a first portion of the tube. The second roll is unrollable to cover the first portion of the tube, the wound contact layer, the absorbent pad, and the stump with a second portion of the tube.
In some embodiments, the tube is configured to supply a compressive force that couples the wound contact layer to the stump. In some embodiments, the tube is configured to supply a compressive force that resists swelling of the stump. In some embodiments, the amputation dressing includes a hip attacher configured to couple the tube to a support belt.
In some embodiments, wherein the wound contact layer comprises an anti-microbial material. In some embodiments, the wound contact layer comprises a silicone-coated mesh or film. In some embodiments, the tube includes an elasticated cotton material or a spandex material.
In some embodiments, each petal has a first end positioned proximate the central panel and the first ends combine to form a perimeter of the central panel. In some embodiments, each petal has a second end opposite the first end. The second end having a second width different than a first width of the first end. In some embodiments, each petal is substantially rectangular.
In some embodiments, the dressing includes a pad positioned between the wound contact layer and the tube. In some embodiments, the pad includes a foam material. In some embodiments, the foam material includes a plurality of slits in a mango-cut pattern.
Another implementation of the present disclosure is a method of treating an amputation stump. The method includes positioning a wound contact layer abutting an amputation wound on the amputation stump by aligning a central panel of the wound contact later with a distal end of the amputation stump and positioning three or more petals of the wound contact layer along the amputation stump. The three or more petals extend from the central panel. The method also includes unrolling a first portion of a tube of elastic material over the wound contact layer and the amputation stump and unrolling a second portion of the tube over the first layer, the wound contact layer, and the amputation stump.
In some embodiments, the method includes providing, by the tube, a compressive force that couples the wound contact layer to the amputation stump. In some embodiments, the method includes providing, by the tube, a compressive force that resists swelling of the amputation stump. In some embodiments, the method includes positioning a support belt around a waist of a patient, coupling the support belt to a hip attacher, and coupling the hip attacher to the tube.
In some embodiments, positioning the three or more petals includes substantially covering a circumference of the amputation stump with the three or more petals. In some embodiments, positioning the three or more petals comprises preventing overlap between the three or more petals. In some embodiments, the method includes positioning a pad between the wound contact layer and the tube. In some embodiments, the method includes aligning the pad with the distal end of the amputation stump.

The amputation stump 100 is a remaining portion of an extremity of a patient following an amputation procedure to remove a distal portion of that extremity. For example, in some cases the amputation stump 100 may be a remaining portion of an arm or a leg. In some cases, the amputation stump 100 may include a remaining portion of a hand or foot of the patient. The amputation stump 100 includes a distal end 104. Surgical wounds such as suture lines (i.e., areas where surgical incisions are closed with sutures) may be positioned on the distal end 104, extending from the distal end 104 along a length of the stump 100 (i.e., towards the patient's torso), circumferentially around the amputation stump 100, or some combination thereof.
The amputation dressing 102 is configured to facilitate healing of surgical wounds on the amputation stump 100 while also providing compression to the amputation stump 100. By providing wound treatment and compression in a single dressing, the amputation dressing 102 may reduce the time required to dress the amputation stump 100, reduce the bulkiness of the amputation dressing 102 relative to conventional dressing approaches, and reduce or eliminate the risk of pressure injury or other discomfort relative to conventional dressing approaches.
The wound contact layer 106 is configured to contact one or more surgical wounds on the amputation stump 100. The wound contact layer 106 is made of a material that prevents or substantially prevents adherence to the wound, allowing for gentle and atraumatic removal of the dressing 102 from the wound. For example, the wound contact layer 106 may include silicone, for example a silicone-coated mesh or film. In some embodiments, the wound contact layer 106 may include an antimicrobial material, for example a silicone mesh impregnated with povidone iodine slurry. In various other embodiments, the wound contact layer 106 may be manufactured from silicone gel on a mesh of one or more of cellulose acetate, viscose rayon, polyamide, or polyethylene terephthalate (PET). In some embodiments, the wound contact layer 106 may be coated with petrolatum or lipidocolloid. The wound contact layer 106 may be flexible and extensible to allow the wound contact layer 106 to conform to the contours of the amputation stump 100.
As shown in
The tube 107 is shown to include a first portion 112 and a second portion 114. In the state shown in
The tube 107 may be made of an elastic material, for example an elasticated cotton material or a spandex material. In various embodiments, the tube 107 may be manufactured from one or more of woven cotton, PET, or cellulose fibrous material incorporating elastic fibers (e.g., Lycra). For example, the tube 107 may include two-layer short stretch compression stockings. Due to the elasticity of the material of the tube 107, the tube 107 may provide a compressive force when stretched over (i.e., positioned on) an amputation stump 100. This compressive force may act to couple the wound contact layer 106 to the stump 100 (e.g., to substantially hold the dressing 102 in place on the stump 100). The compressive force provided by the tube 107 may also resist and/or substantially prevent swelling of the stump 100, for example to help avoid stump oedema. For example, the tube 107 may provide a therapeutic level of compression (e.g., between approximately 15 mmHg and 40 mmHg) and/or a static stiffness index (e.g., greater than 10 mmHg).
In some embodiments, the tube 107 may include absorbent materials, such as those described with reference to the absorbent pad 200 below. For example, in some embodiments the first portion 112 includes one or more absorbent materials while the second portion 114 includes one or more compressive materials. As another example, the tube 107 may include absorbent fibers of carboxyl methyl cellulose. As another example, the tube 107 may include sodium polyacrylate superabsorbent fibers or particles.

In preferred embodiments, the wound contact layer 106 includes three or more petals 108. For example, in the embodiment shown in
Each petal 108 has a first end 300 adjacent to the central panel 110, a second end 302 opposite the first end 300, and edges 304 that extend from the first end 300 to the second end 302. In the embodiment shown, the first end 300 and the second end 302 are substantially straight and parallel with a substantially equal width, and the edges 304 are substantially straight and have substantially equal lengths. Accordingly, in the embodiment shown, each petal 108 is substantially rectangular. In various other embodiments, various shapes of the petals 108 are possible. For example, in some embodiments one or more of the first ends 300, second ends 302, and edges 304 may be curved or otherwise non-straight. In various embodiments, the width of the first end 300 may different (i.e., wider or narrower) than the width of the second end 302 and/or the edges 304 of a petal 108 may have unequal lengths. For example, the petal 108 may be trapezoidal. As another example, in some embodiments each petal 108 has a mid-region that may be wider or narrower than the first end 300 and/or the second end 302. In some embodiments, each petal 108 has substantially equal dimensions (e.g., the widths of each of the first ends 300 and second ends 302 are substantially equal). In other embodiments, two or more petals 108 have different dimensions.
In the embodiment shown in
Various dimensions and ratios of dimensions are possible for the central panel 110 and the petals 108. The central panel 110 may be of a suitable size to cover the distal end 104 of an amputation stump 100, while the petals 108 may be of suitable sizes and shapes to cover surgical wounds positioned along the amputation stump 100. Accordingly, the dressing 102 may be manufactured in various sizes and relative dimensions for use with various patients of various sizes, various amputation locations (e.g., above the knee, below the knee, above the elbow, below the elbow), various surgical wounds, etc.
Referring now to
The absorbent pad 200 is configured to absorb wound exudate from one or more surgical wounds on the amputation stump 100 and/or provide cushioning to protect the one or more wounds and provide comfort for the patient. The absorbent pad 200 may be made of a foam, for example a polyurethane foam. In various embodiments, the absorbent pad 200 may be manufactured from one or more of TIELLE Hydropolymer foam by Systagenix or GranuFoam by Acelity. In some embodiments, a foam material of the absorbent pad 200 may be laminated or wrapped in a non-adherent such as ethyl methylacrylate. In some embodiments, the absorbent pad 200 may incorporate an antimicrobial material such as silver fibers or polyhexanide (PHMB). The material of the absorbent pad 200 may be at least partially flexible to facilitate conformance to contours of the amputation stump 100 (e.g., of the distal end 104 of the amputation stump 100).
The absorbent pad 200 includes a bottom surface 400 positioned adjacent the wound contact layer 106 and a top surface 402 positioned opposite the bottom surface 400. The absorbent pad 200 may be substantially circular, for example as shown from the top view of
As shown in
In the example of
