DETAILED DESCRIPTION OF THE INVENTION

[0030] The Aislante de Pie Diabéico Ulcerado (APDU) is a medical device that is placed on the leg as a frame (2) made up of a rear casing (3) and a front casing (4) that covers from the distal portion of the thigh (above the knee) from the affected limb to the soles of the feet.

[0031] The APDU made up of a rear casing (3) and an external front casing (4) that adjust to the leg and foot allows said anatomical elements to be isolated, from the environment by means of a mesh (1) type of mosquito netting and/or fabric for women's stockings (panti stocking type) very porous, with tiny holes that rests and extends over the casing, giving rise to a delimitation that prevents the entry of external pathogens. The way in which the device is attached to the leg is through contact points that serve as support (5,24) giving firmness and immobility and through spacers (39-60), which allow stability, the latter made of a material semi-rigid, comfortable and hypoallergenic, such as: Viscoelastic foam (memory foam), Carbonic Snow, among others

[0032] The casing or frame that constitutes the APDU can be easily disassembled to allow sanitization of the leg, the foot, or both, by removing the mesh (1) that covers said frame (2), since it is disposable, so it can be replaced in the reusable version or it can be attached to the frame (2) in its disposable version, then, the total exposure of the member is achieved by separating the rear casing (3) from the front casing (4) with the removal first, of the closing hooks of casing (20-24) found on both sides of it.

[0033] In a cephalo-caudal description, an expandable band support is observed that corresponds to the upper support (5), it has six female adapters (7-12), made of a material that resists pressure, located equidistant as follows: front adapter (7), rear adapter (8), two internal side adapters (9,10) and two external side adapters (11,12). These adapters have a closed upper end and an open lower end that receive the so-called vertical bars that, according to their location, will receive the name according to the axis and specific position.

[0034] Next we find six bars that, depending on the version, these will be made of plastic or another rigid and light material such as aluminum. Depending on the arrangement and combination of materials, there is a disposable and a reusable version. The bars are arranged as follows: an anterior vertical bar (13); four lateral vertical bars that are: the anterior internal vertical bar (14), the posterior internal vertical bar (15), the anterior external vertical bar (16), the posterior external vertical bar (17) and a descending posterior vertical bar (18). The bars, anterior vertical (13) and descending posterior vertical (18) are directed downwards with respect to their position from the level of the upper ring (5) to the foot and at the level of the plantar base (19) they perform a turn; the descending posterior vertical bar (18) from behind towards the front and the anterior vertical bar (13) towards the back, making a false union of said bars at the level of the heel area of the foot. Where they make the union of the vertical posterior descending (18) and anterior (13) bars, each one of these bars represents the complement of the bars arranged laterally and that will give rise to the formation of one or the other half of the anterior carcass (3) and/or rear casing (4).

[0035] Continuing with the cephalo-caudal direction, a set of spacers can be seen that together form the discontinuous rings of spacers (33-36). In the case of the rear shell (3), each spacer is attached to three bars, the rear outer vertical bar (17), the rear inner vertical bar (15) and the descending rear vertical bar (18) and the other spacers in the case of the front shell (4), also three bars: the anterior external vertical bar (16), the anterior internal vertical bar (14) and the anterior vertical bar (13). In this way, the spacers are arranged to form a discontinuous ring in the space between the upper support (5) and the lower support (29). 15 There are four discontinuous rings found in the mentioned space. One below the knee, ring A (33), another at the level of the gastrocnemius muscles, ring B (34) where this has the peculiarity of not having posterior support since the leg rests on the large pad (26) placed there, the third discontinuous ring of separators, ring C (35) placed in the area between the gastrocnemius muscles and the ankle area and a D ring (36) placed in the ankle area, also with the particularity of not having a posterior separator. These separators depending on the ring to which they belong, will be placed the letter of their level and next to it with the initials DEL, to indicate forward; POS, to indicate later; LATi-DEL and LATiPOS, to indicate that it is on the front or rear internal side respectively and LATeDEL and LATePOS to indicate that it is on the front or rear external side in the same way, this accompanied by the letter of the ring to which they belong; example: BLATiDEL(45).

[0036] The first ring, ring A (33) located below the knee, in the upper third of the leg, is formed by four quarter moons that serve as separators (37-42) where those corresponding to the sides are divided into two front (40.41) and two rear (39.42) each attached to the casing on the inside. Fora good understanding of this part of separator rings, it is enough to describe one of them because, despite having a certain peculiarity regarding the absence of the rear separator at certain levels, it will be enough to understand the legend exposed in the marked drawings. Ring A, located between the knee and above the gastrocnemius muscles, has four quarter moons, the front separator A (37), one posterior, the posterior separator A (38), two internal ones; separator A LATiPOS (39) and separator A LATiDEL (40), and two external ones; separator A LATeDEL (41) and separator A LATePOS (42).

[0037] The shape of the foot is made up of five almost rounded rings (66,67,68,69,70) where three of them locate their hole perpendicular to the front face of the area that houses the heel, front, middle and rear rings (66,67,68), the other two rings (69,70) are transversally where their hole points parallel to the face of the plantar base; upper plantar ring (69) and lower plantar ring (70). The heel zone is delimited in the lower portion of the leg superiorly by the posterior hoop (68), laterally by two bars, the posterior external vertical bar (17) and the posterior internal vertical bar (15). In the lower part, three plantar crossbars: anterior, middle and posterior respectively (73,74,75) and a plantar inferior sagittal bar (71) that crosses them perpendicularly, thus giving rise to the plantar base (19). Note that an optional insole space 76 is left one-half to one inch between the plantar surface and the inner face of the APDU plantar shape to add an insole for the user's foot if desired.

[0038] Some casing closing hooks (20,21,22,23,24) allow the approximation of the two casings that make up the APDU (3,4). One part of the hooks is located at the front and the other at the back. The location of each of them is on the external and internal vertical bars (14-17) at the level of the following structures: ring B (34) and ring C (35), close to the ankle area (87) and in the plantar base at the level of the lower plantar rim (70).

[0039] The APDU also comes with a fan (77) that blows air directly into the wound in order to keep it dry. The fan (77) can be attached to a belt; fan retaining strap (78) and sticks to the case firmly. It can work with an AC power supply (Alternating Current) (79) or through batteries for DC power (Direct Current) (80). The power supply cable (81) allows mobility given its length, greater than 5 meters.

[0040] The fan (77) with blades (82) that blow direct air also has a fluorescent lamp (84) on the front that emits ultraviolet light, which has a timer that allows it to turn on and off automatically. Said ultraviolet light has the function of contributing to prophylaxis and treatment, stopping the growth of microorganisms and helping to eliminate what is already there. A fan fastening strap (78) that has the fan (77) can be positioned according to where it is needed, such as moving it from the plantar area to the dorsal part of the foot. Its position is fixed thanks to a closing clasp (86) made of resistant material that can only be attached by pressing on the sides of the head once they are joined. A ticking on/off switch on the sides of the fan allows fan activation; fan switch (83) while another tick-tock will be in charge of activating the ultraviolet light; ultraviolet light switch (85).

[0041] The APDU has a support zone that allows the patient to rest his leg either sitting or lying down, this is the rest support base assembly (CBAD) (59). The CBAD is made up of bars for the support base (60) which are two long tubes that have two parallel slots that, seen in a cross section, form an angle of 90 degrees, one of the slots; the adhesion slot for the rectangular flat base (62) allows the union between both bars (60) through the rectangular flat base of the support base (63), the other slot; the adhesion slot for support dockable bar (61) allows the union of the adhesion supports of the base assembly (64) that are a total of three pairs so that these in turn adhere to the rear casing (3) giving rise to the set of support base as such (59).

[0042] In the back case (3) there are four structures: a large pad tray (25), a large pad (26), a small pad tray (27) and a small pad (28). The large pad tray (25) located at the level of the gastrocnemius muscles is concave on the inside and slightly convex on the outside. On its internal face rests a pad, a large pad (26) that will serve as a support for the leg when the patient is sitting or lying down. Said pad will maintain its position thanks to a glue for such purposes. The support area located at ankle level will have the same characteristics, where we will have the small tray for the pad (27) and the small pad (28) respectively.
