[0016] FIGS. 2a to 2k: Schematic depiction of the steps to position the foot bandage of FIG. 1 on a foot of a patient.

DETAILED DESCRIPTION

[0017] The foot bandage depicted in FIGS. 1a and 1b includes the sole section 1 and side sections 2, 3 connected laterally to the sole section 1. Each side section 2, 3 is then expediently joined, especially stitched, to the sole section 1 along the horizontal seam 11. However, it is also possible to form the sole section 1 and the side sections connected to it in one piece and therefore seamlessly.

[0018] The two side sections 2, 3 are joined to each other by a vertical seam 10 in an area 2a, 3a above the heel. When the foot bandage is applied, the vertical seam 10 runs in the vertical direction above the heel in the area of the Achilles tendon of the patient. The foot bandage has a recess 13 in the heel area. Cushioning is preferably incorporated in the sole section 1 in order to increase wearing comfort. The cushioning can be sewn, for example, onto an outside of the sole section 1.

[0019] Each side section 2, 3 has a proximal edge 2b, 3b and a distal edge 2c, 3c. A tab section 4, 5 is arranged in each side section 2, 3 between the proximal edge 2b, 3b and the distal edge 2c, 3c. The extensions of the proximal edge 2b, 3b and the distal edge 2c, 3c then meet at an angle between 40 and 50° and preferably at an angle of 45°.

[0020] The sole section 1, the two side sections 2, 3 and each distal tab section 4, 5 are then expediently made from an elastic material, for example, an elastic short-pull textile material. The elastic material expediently has a maximum range of elongation between 15 and 50% of the unstretched state. The elastic material can be a textile fabric made of polyamide and spandex, for example, with 87% polyamide and 13% spandex, relative to the weight of the textile fabric. The maximum elongation of the elastic material preferably lies in the range from 15 to 50% of the unstretched length and with particular preference either between 15 and 20% or between 25 and 35%.

[0021] Each distal tab section 4, 5 includes in the embodiment example depicted in the drawing two pull tabs 4a, 4b and 5a, 5b. The pull tabs 4a, 4b and 5a, 5b of a tab section 4, 5 are separated from each other by an indentation 12 in the corresponding tab section 4, 5.

[0022] Fasteners 6 are arranged on at least one of the two distal tab sections 4, 5 for fastening of the foot bandage to a foot of a patient. These fasteners 6 are expediently a hook-and-loop fastener. The fasteners 6 in the embodiment example depicted in the drawing are removably arranged on a free end of the two pull tabs 5a, 5b of a tab section 5.

[0023] The part of the foot bandage consisting of the sole section 1 and the side sections 2 and 3 with the distal tab sections 4, 5 can be fastened under tension to the foot of the patient by means of fastener 6 so that this part of the foot bandage exerts a compression pressure on the foot. The compression pressure exerted on the foot when the foot bandage is applied, depending on the set elongation, expediently lies in the range between 8 and more than 40 mmHg and can be set to compression values up to 60 mmHg. Elongation of the elastic material then occurs by manual tension on the distal tab sections 4, 5 and is fixed by attaching fastener 6. For this purpose, the distal tab sections 4, 5, on which the pull tabs 4a, 4b and 5a, 5b are arranged are wound around the instep, and the distal tab section 5, on the pull tabs 5a, 5b of which the fasteners 6 are arranged, is fastened under tension by means of fastener 6 to the opposite side section 2. Positioning of the foot bandage on a foot is explained below in further detail with reference to FIGS. 2a to 2k.

[0024] The foot bandage according to the invention also includes a removable proximal compression band 7. This compression band 7 is shown in the open state in the depiction of FIG. 1a and in the closed state in the depiction of FIG. 1b. The proximal compression band 7 is removably fastened to side sections 2, 3 when the foot bandage is applied. Like the sole section 1 and the side sections 2 and 3 with the distal tab sections 4, 5, the proximal compression band 7 is also expediently formed from an elastic material, i.e., from the same elastic material as a sole section and the two side sections with the tab sections. For removable fastening of the proximal compression band 7 to the side sections 2, 3 the proximal compression band has a first fastener 8. The first fastener 8 is expediently formed by a hook part of a hook-and-loop fastener, which is fastened to a central location, especially stitched, on the inside of compression band 7. The first fastener 8 is apparent in the depiction of FIG. 1a. The proximal compression band 7 is fastened by means of the first fastener 8 in the area 2a, 3a above the heel on the outside of side sections 2, 3. To exert a compression pressure, the proximal compression band 7 is wrapped around a section of the lower leg of the patient and fastened there by means of a second fastener 9 under elongation of the proximal compression band. The proximal compression band 7 then has a first end section 7a and a second end section 7b, second fasteners 9 being provided on at least one of the two end sections 7a. The second fasteners 9 are expediently a hook-and-loop fastener and especially a hook part of the hook-and-loop fastener removably fastened to end section 7a.

[0025] Positioning of the foot bandage on the foot of a patient is explained below with reference to FIGS. 2a to 2k. For this purpose, the part of the foot bandage consisting of the sole section 1 and the two side sections 2 and 3 with the distal tab sections 4, 5 is initially positioned on the foot of the patient, as shown in FIG. 2a, the sole section 1 coming to lie in the area of the sole of the foot and the two side sections 2, 3 with the distal tab sections 4, 5 arranged on them being wound around the instep. The vertical seam 10, through which the two side sections 2, 3 are joined to each other, then comes to lie in the area of the Achilles tendon and the vertical seam 10 runs essentially in the vertical direction. The recess 13 lies in the area of the heel of the patient.

[0026] By manual tension on the pull tabs 4a, 4b and 5a, 5b of the distal tab sections 4, 5 compression is exerted on the foot of the patient. This compression is fixed by fastening the pulled tab sections 4, 5 on the opposite side sections 2, 3. For this purpose, the fasteners 6 arranged on the free ends of pull tabs 5a, 5b of a tab section 5 are fixed on the outside of the opposite side section 2. The fasteners 6 are then expediently designed to be removable. This makes it possible to use the foot bandage for both the right and left foot. Fastening of the fastener 6 to the free ends of pull tabs 5a, 5b of a distal tab section 5 is shown in FIG. 2b. The fasteners 6 are hook-and-loop fasteners, whose hook part is joined to one section on the outside of the free end of the pull tabs 5a, 5b. Another section of the fastener 6 then remains free so that it can be joined to the outside of the opposite side section 2.

[0027] For fixation of the foot bandage on the foot, a first pull tab 5b and then the second pull tab 5a of a distal tab section 5 are initially attached by fastener 6 to the outside of the opposite side section 2, as shown in FIGS. 2c, 2d and 2e. Tension is then exerted on the tab section 5 via pull tabs 5a, 5b, which is transferred to the side section 3 and the sole section 1. By attaching the fastener 6 of the pull tabs 5a, 5b to the opposite side section 2, the elongation produced by tension on the elastic material is fixed so that compression is exerted on the foot of the patient.

[0028] The proximal compression band 7 is then fastened in the area of the lower leg of the patient. For this purpose, the inside of the proximal compression band 7 is initially fastened by means of the first fastener 8 to the outside of side sections 2, 3. Fastening then occurs in the area 2a, 3a of side sections 2, 3 that lies above the heel. Fastening of the proximal compression band 7 to the side sections 2, 3 via the first fastener 8 is shown in FIG. 2f. The precise position of the proximal compression band 7 can then be correspondingly adjusted to the individual requirements of compression therapy, in which case the proximal compression band 7 can be pushed in the proximal-distal direction. The proximal compression band 7 can therefore be positioned and fastened in the section of the lower leg or also in the area of the ankle joint of the patient.

[0029] For fastening of the proximal compression band 7 to a desired location on the lower leg or ankle joint of the patient, removable second fasteners 9 are initially arranged on one of the end sections 7a of the proximal compression band 7, as shown in FIG. 2g. The second fasteners 9 are expediently hook parts of a hook-and-loop fastener, which are firmly joined to the outside of the proximal compression band 7 in the area of one of the end sections 7a. A second fastener 9 is also expediently arranged, as shown in FIG. 2h, on the other end section 7b of the proximal compression band 7. The proximal compression band 7, as shown in FIG. 2g, is then fastened by means of the second fastener 9 initially to an end section 7a on the outside of the side section 3 of the foot bandage. The other end section 7b of the proximal compression band 7 is then also fastened to the opposite side section 2 of the foot bandage by means of the second fastener 9. The proximal compression band 7 is then manually held under tension and this tension is fixed by attaching the second fastener 9 so that the proximal compression band 7 also exerts compression on the lower leg or foot of the patient in the area of the ankle joint. The positioned foot bandage in a top view of the foot of the patient is shown in FIG. 2k.

[0030] When the tab sections 4, 5 are fastened to the opposite side sections 3 and 2, it must be kept in mind that the foot of the patient is fully enclosed by the side sections 2 and 3 and tab sections 4, 5, so that no free locations form through which body tissue might swell. The proximal compression band 7 should also be correspondingly positioned so that it at least partially overlaps the side sections 2, 3.

[0031] The invention is not restricted to the embodiment depicted in the drawings. For example, the number of pull tabs of the tab sections 4, 5 can be adjusted to the size of the bandage and the anatomy of the foot. In longer bandages, each tab section 4, 5 can also include three or more pull tabs; and in shorter bandages, only one pull tab can be sufficient. It is also sufficient if a tab section with at least one pull tab is arranged only on one of the two side parts 2, 3. The embodiment of the invention with tab sections 4, 5 on both side parts 2, 3 depicted here, however, has the advantage that the foot bandage can be used for both a right and left foot.

[0032] The elongation characteristics of the elastic materials are variable over a wide range and can be adjusted to the requirements of the compression treatment to be performed with the bandage. Other fasteners instead of hook-and-loop fasteners can also be used, such as press studs or hook-and-eye closures.
