Description

Heel guard

The present disclosure relates to a heel protector.

Bedsores are conditions in which blood circulation is disrupted due to continuous and repeated pressure applied to a body part while sitting or lying down in one position, causing damage (ulcers) to the skin and subcutaneous tissue. Bedsores mainly occur in areas where bones protrude and are easily subject to pressure, such as the heels, elbows, and buttocks. Bedsores are classified into suspected deep tissue, stage 1, stage 2, stage 3, stage 4, and unclassified bedsores (where the depth of tissue damage is unknown because the wound bed is covered with dead tissue; stage 3 and stage 4 bedsores often develop after the dead tissue is removed) depending on the degree of progression. Stage 1 bedsores cause continuous redness and inflammation of the epidermis, stage 2 bedsores are superficial ulcers and blisters that are destroyed only up to the dermis layer, but from stage 3 bedsores, they develop into ulcers in which the entire layer, including the skin and subcutaneous fat, is destroyed, but does not extend beyond the fascia. And the fourth stage of bedsores is a complete destruction of the entire layer, and damages the muscles, ligaments, and bones. According to the National Statistical Office, the number of deaths in Korea due to 'bedsore ulcers and pressure areas' from 2015 to 2017 was about 370 people per year on average, and the cost of bedsore treatment was found to be about 30 billion won per year. In addition, the number of deaths due to bedsores and the cost of bedsore treatment are continuously increasing due to the rapid aging of the population.

Bedsores occur frequently, especially in patients who spend long periods of time in bed, and bedsores occur frequently due to pressure on the heels. To prevent bedsores, there are heel pads, but there is a problem that they can easily come off the heel with just a slight movement of the patient's body, rendering them ineffective. To prevent pads from coming off, bandage stockings are sometimes worn while the heel pad is attached, but this is only a temporary measure and is also unstable.

As a prior art for solving these problems, there is a protector disclosed in U.S. Patent Publication No. 4,076,022. However, the protector has a connecting member such as a buckle inserted into the sole or the inside of the calf, so when the protector is worn for a long time, the connecting member presses the patient's sole or calf, which inevitably causes discomfort to the patient. In addition, the protector uses Velcro as a connecting member, but when the Velcro is used repeatedly, the adhesive strength decreases, so the protector cannot be properly fixed, and there is a problem that it must be replaced.

Another prior art is a brace disclosed in Chinese Patent Publication No. 105616049. However, the brace is fixed using a belt, buckle, and ring, which is not only difficult for a patient who has been bedridden for a long time and has lost a lot of muscle strength to wear, but the metal buckle and ring also put pressure on the patient's instep, ankle, shin, and calf, causing discomfort to the patient.

Another prior art is a protector disclosed in Korean Patent Publication No. 10-2249207. However, the protector is wrapped with a cushion from the lower part of the calf to the entire sole of the foot, so the patient may have skin problems worsen due to sweat generated when wearing the protector for a long time. In addition, the protector also uses Velcro to attach and detach the connecting member, so the adhesive strength may decrease with repeated use.

Such prior art is technical information that the inventor possessed for the purpose of deriving the present invention or acquired during the process of deriving the present invention, and cannot necessarily be said to be publicly known technology disclosed to the general public prior to the application for the present invention.

A heel protector according to embodiments of the present disclosure can provide a heel protector that does not come off or move while worn by a patient, does not put pressure on the patient's body, and can be easily fastened and disassembled by the patient.

The embodiments of the present disclosure can be understood by referring to the description and drawings of the invention. The described embodiments can have various modifications and can be implemented in different forms and are not limited to the embodiments described in the present specification. In addition, each feature of the various embodiments of the present disclosure can be combined in part or in whole with each other. Each embodiment can be implemented independently of each other or in relation to each other. The described embodiments are provided as examples so that the present disclosure can be complete and thorough, and completely convey the spirit of the present disclosure to those skilled in the art. The present disclosure can be replaced within the spirit and technical scope of the present disclosure with all modifications, equivalents, and substitutions. Therefore, processes, elements, and techniques that are not necessary for those skilled in the art for a complete understanding of the embodiments of the present disclosure may not be described.

Unless otherwise stated throughout the attached drawings and specification, the same reference numerals, letters or combinations thereof indicate the same components, and thus, redundant descriptions are omitted. In addition, in order to clearly explain the present invention, parts that are not related to the explanation are omitted.

The relative sizes of elements, layers, and areas in the drawings may be exaggerated for clarity. The use of hatching and/or shading in the attached drawings is generally provided to clarify boundaries between adjacent elements. Therefore, the presence or absence of hatching or shading does not imply a desirable form or requirement for any particular material, material property, dimension, proportion, commonality between the drawing elements, and/or any other characteristic, property, or attribute of the elements unless otherwise specified.

Various embodiments are described herein with reference to cross-sectional examples, which are schematic illustrations of embodiments and/or intermediate structures. Therefore, the shape of the drawings may vary, for example, as a result of manufacturing techniques and/or tolerances. In addition, the specific structural or functional descriptions disclosed herein are merely examples for explaining embodiments according to the concept of the present invention. Therefore, the embodiments disclosed herein should not be construed as being limited to the shape of the regions illustrated, and include, for example, deviations in shape due to manufacturing.

The areas depicted in the drawings are schematic in nature and their shapes are not intended to be limiting and are not intended to be illustrative of actual shapes of the device areas. Furthermore, as will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present disclosure.

Numerous specific details are set forth in the specification to provide a thorough understanding of the various embodiments. However, various embodiments may be practiced without these specific details or with one or more of the details. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring the various embodiments.

To facilitate the discussion herein, spatially relative terms such as “below,” “above,” “lower,” “top,” and the like may be used to describe the relationship of one element or feature to another, as illustrated in the drawings. The spatially relative terms are intended to encompass various orientations of the device in use or operation in addition to the orientations depicted in the drawings. For example, if the device in the drawings were flipped over, another element or feature described as “below” or “lower” would be oriented “above” the other element or feature. Thus, the exemplary terms “below” and “lower” can encompass both the above and below orientations. The device can be oriented in other orientations (e.g., rotated 90 degrees or in other directions) and the spatially relative descriptions used herein should be interpreted accordingly. Likewise, when a first part is described as being disposed “above” a second part, this means that the first part is disposed above or below the second part.

Also, the expression "in plan view" means when an object is viewed from above, and the expression "in schematic cross-section" means when a schematic cross-section is taken by cutting the object vertically. The term "in side view" means that the first object can be above or below or to the side of the second object, or vice versa. Additionally, the term "overlapping" or "superimposing" can include layer, laminate, plane, extension, covering, or partially covering, or any other suitable term that a person of ordinary skill in the art would understand and understand. The expression "does not overlap" can include meanings such as "away from" or "spaced from" and any other suitable equivalents recognized and understood by a person of ordinary skill in the art. The terms "plane" and "surface" can mean that the first object can directly or indirectly face the second object. When a third object is between a first object and a second object, the first object and the second object face each other, but can be understood as indirectly opposing each other.

When an element, layer, region or component is referred to as being "formed by," "connected to," or "coupled to," another element, layer, region or component, it can be directly formed by, connected to, or coupled with the element, layer, region or component, or formed by, connected to, or coupled with another element, layer, region or component indirectly. Additionally, "formed by," "connected to," or "coupled" can collectively refer to direct or indirect bonding or connection of elements, layers, regions or components, and integral or non-integral bonding or connection, such that more than one element, layer, region or component may be present. For example, when an element, layer, region or component is referred to as being "electrically connected to," or "electrically coupled to," another element, layer, region or component, it can be directly electrically connected or coupled to the other element, layer, region or component, or other elements, layers, regions or components may be present. However, "direct connection" or "direct bonding" means that one component is directly connected or bonded to another component without an intermediate component, or is on another component. In addition, in the present specification, when a part of a layer, film, region, guide plate, etc. is formed on another part, the direction of formation is not limited to the upper direction, and includes that the part is formed on the side or the lower side. On the other hand, when a part of a layer, film, region, guide plate, etc. is formed "under" another part, it includes not only the case where the part is "directly under" the other part, but also the case where there is another part between the part and the other part. Meanwhile, other expressions that describe the relationship between components, such as "between," "directly between," or "adjacent to" and "directly adjacent to" may be interpreted similarly. In addition, when an element or layer is referred to as being "between" two elements or layers, it may be the only element between the two elements or layers, or there may be another element between them.

For the purposes of this specification, phrases such as "at least one or more" or "either" do not limit the order of the individual elements. For example, phrases such as "at least one of X, Y, and Z", "at least one of X, Y or Z", "at least one selected from the group consisting of X, Y, and Z" can include X alone, Y alone, Z alone, or any combination of two or more of X, Y, and Z. Similarly, phrases such as "at least one of A and B" and "at least one of A or B" can include A, B, or A and B. The term "and/or" as used herein generally includes any combination of one or more of the associated list items. For example, phrases such as "A and/or B" can include A, B, or A and B.

Although the terms "first," "second," "third," etc. may be used herein to describe various elements, components, regions, layers, and/or sections, such elements, components, regions, layers, and/or sections are not limited by such terms. Such terms are used to distinguish one element, component, region, layer, or section from another element, component, region, layer, or section. Thus, a first element, component, region, layer, or section described below may be referred to as a second element, component, region, layer, or section without departing from the spirit and scope of the present invention. Describing an element as a "first" element does not require or imply the presence of a second element or other elements. The terms "first," "second," etc. may also be used herein to distinguish different categories or sets of elements. For clarity, the terms "first," "second," etc. may each represent a "first category (or first set)," a "second category (or second set)," etc.

The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms "a" and "an" are intended to include the plural forms as well, and the plural forms are intended to include the singular form, unless the context clearly indicates otherwise. The terms "comprises," "includes," and "having" when used herein are meant to specify the presence of stated features, integers, or steps. These expressions do not preclude the presence or addition of one or more other functions, steps, operations, components, and/or groups thereof.

Where one or more embodiments may be implemented differently, a particular process sequence may be performed differently from the order described. For example, two processes described in succession may be performed substantially simultaneously or in the reverse order from the order described.

The terms "substantially", "about", "approximately" and similar terms are used as terms of approximation rather than degree, and mean satisfying the inherent range of variation (e.g., due to limitations of the measurement system) of the measured or calculated value. For example, "about" can mean within one or more standard deviations, or within ±30%, 20%, 10%, or 5% of the stated value.

Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Terms defined in commonly used dictionaries, such as terms defined in commonly used dictionaries, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and/or this specification, and will not be interpreted in an idealized or overly formal sense unless explicitly defined herein.

FIG. 1 illustrates a heel protector (10) according to one embodiment, FIG. 2 illustrates a state in which a patient wears the heel protector (10) of FIG. 1, FIG. 3 illustrates a first connecting portion (300) of FIG. 1, and FIG. 4 illustrates a state in which the first connecting portion (300) of FIG. 1 is connected.

The heel protector (10) is a medical auxiliary device for protecting and supporting the heel of a patient, and can prevent bedsores from forming on the heel of a patient who is bedridden for a long time due to the heel being pressed against the bed. As shown in Fig. 2, when a patient wears the heel protector (10), the heel protector (10) can be positioned on the heel, sole, shin, and calf of the patient. The heel protector (10) can be made of a material suitable for medical use that does not cause rashes on the skin even when worn for a long time. For example, the heel protector (10) can include at least a portion of natural rubber or chloroprene rubber, TPU (Thermoplastic Poly Urethane), TPE (Thermo Plastic Elastomer), etc. In addition, the heel protector (10) can include various medical materials. In addition, the heel protector (10) can be made of a deformable elastic material. The heel protector (10) can be made of an integral part or can be made of different separate components combined together.

The heel protector (10) may include a main body (100), a cover part (200), a first connection part (300), and a second connection part (400). The heel protector (10) may include a main body (100) corresponding to a patient's calf, a cover part (200) connected to the main body (100) and having an inner side concave so that the patient's heel may be inserted, a first connection part (300) extending from the cover part (200) and including a plurality of first insertion grooves (310) along a longitudinal direction and a plurality of first insertion protrusions (320) formed between the plurality of first insertion grooves (310), and a second connection part (400) extending from the main body (100) and including a plurality of second insertion grooves (410) along a longitudinal direction and a plurality of second insertion protrusions (420) formed between the plurality of second insertion grooves (410).

The main body (100) can support and connect the cover part (200), the first connection part (300), and the second connection part (400). The main body (100) can have a long shape in one direction so that it can support the calf (C) while the patient is wearing the heel protector (10). For example, as shown in FIGS. 1 and 2, the main body (100) can have one end connected to the cover part (200) in the length direction, and two second connection parts (400) can be positioned on both sides in the width direction. The main body (100) can support from the back of the patient's ankle to a part of the calf (C), and can be made of an elastic material that can be deformed to fit the shape of the patient's body.

The cover part (200) is supported on the main body part (100) and can wrap around the heel (H) while the patient is wearing the heel protector (10), thereby dispersing the load applied to the heel (H) and preventing bedsores from occurring on the heel (H). For example, as shown in FIG. 2, the cover part (200) can have an inwardly concave shape to wrap around the heel (H) while the patient is wearing the heel protector (10). The cover part (200) can support the heel (H), a part of the sole of the foot, the pectineus, and the Achilles tendon. At least a part of the cover part (200) can be made of a material that is thicker and softer than other parts of the heel protector (10). For example, one or more layers can be added to the inner side of the cover part (200). The above layer may be made of the same material as the main body (100), the cover (200), the first connecting portion (300), and the second connecting portion (400), or may be made of a different material. For example, the layer may be one or more of memory foam, latex, polyester, bead/bio material, cotton, and sponge. Alternatively, the layer may include an air layer or a fluid layer.

The first connecting portion (300) can support the heel protector (10) so that it does not come off from the patient's body while the patient is wearing the heel protector (10). For example, the first connecting portion (300) can be connected at the instep portion passing the patient's foot (F). As shown in FIGS. 1 and 2, the first connecting portion (300) can include two first connecting portions (300). The two first connecting portions (300) can be connected to each of the two sides of the cover portion (200). The patient can connect the two first connecting portions (300) to each other while wearing the heel protector (10). The two first connecting portions (300) can be connected on the instep of the patient. Alternatively, the number of first connecting portions (300) can be one or three or more. Alternatively, the first connecting portion (300) can include an even number of first connecting portions (300). For example, two first connecting portions (300) may extend from one side of the cover portion (200) and the other two first connecting portions (300) may extend from the other side of the cover portion (200). The first connecting portions (300) may be connected to each other in pairs of two.

The first connecting portion (300) may include a first insertion groove (310) and a first insertion projection (320).

A plurality of first insertion grooves (310) are arranged along the length direction of the first connecting portion (300), and the first connecting portion (300) may be formed by partially cutting the first connecting portion (300) in the width direction. The plurality of first insertion grooves (310) may be spaced apart from each other along the length direction of the first connecting portion (300). In Fig. 1, four first insertion grooves (310) are shown formed in the first connecting portion (300), but the number of first insertion grooves (310) may be appropriately selected in consideration of the patient's body type, etc. The number of first insertion grooves (310) may be four or more, as shown in Fig. 3. Alternatively, the number of first insertion grooves (310) may be four or less. The plurality of first insertion grooves (310) formed in one first connecting portion (300) may be formed in a different direction from the plurality of first insertion grooves (310) formed in another first connecting portion (300). For example, as shown in FIG. 1, when there are two first connecting portions (300), the plurality of first insertion grooves (310) formed in one first connecting portion (300) may extend downward from the upper end of the first connecting portion (300) in the width direction of the first connecting portion (300). And the plurality of first insertion grooves (310) formed in another first connecting portion (300) may extend upward from the lower end of the first connecting portion (300) in the width direction of the first connecting portion (300). That is, the first connecting portion (300) includes a plurality of first connecting portions (300), and two of them are paired and connected to each other, and a plurality of first insertion grooves (310) formed in one of the two first connecting portions (300) that are connected to each other can extend in one direction from the upper end of the first connecting portion (300), and a plurality of first insertion grooves (310) formed in the other can extend in one direction from the lower end of the first connecting portion (300). Therefore, as shown in FIG. 3, when a patient connects the first insertion grooves (310) formed in the two first connecting portions (300) to each other, the two first connecting portions (300) can be connected from above and below so that the first insertion grooves (310) are naturally inserted into each other. The first insertion grooves (310) can be formed deeper than half the width of the first connecting portion (300). Accordingly, the first insertion grooves (310) can be inserted deeply into each other so that the first connecting portions (300) can be reliably connected. In addition, the first insertion grooves (310) can have a shape in which the width gradually narrows along the direction extending from the end. Therefore, the first insertion grooves (310) can be prevented from easily coming off while being inserted into each other. Since the first insertion grooves (310) are formed in multiple numbers, the patient can adjust the connection position considering the size of his or her foot or discomfort. Alternatively, although the first insertion grooves (310) are shown as having a predetermined width in FIG. 1, etc., the first insertion grooves (310) can have a slit shape. That is, the first insertion grooves (310) can be formed in a line shape.

The first insertion projection (320) is located between the first insertion grooves (310) and can be formed with a wider width than the first insertion grooves (310). When the first insertion groove (310) formed in one first connecting portion (300) is inserted into the first insertion groove (310) formed in another first connecting portion (300), the first insertion projections (320) formed in each of the first connecting portions (300) overlap each other to firmly support the connection between the first connecting portions (300). For example, as shown in FIG. 4, when two first insertion grooves (310) are inserted into each other, one of the two first insertion protrusions (320) formed in one first connecting portion (300) is above one first insertion protrusion (320) of the other first connecting portion (300), and the other is below one first insertion protrusion (320) of the other first connecting portion (300). That is, when the two first connecting portions (300) are connected to each other, the first insertion protrusions (320) intersect each other with respect to the first connecting portion (300). In FIG. 4, the dotted lines indicate the ends of the first insertion protrusions (320) respectively located below. For example, the first connecting portion (300) includes two first connecting portions (300), and the two first connecting portions (300) extend from one side and the other side of the cover portion (200), respectively, and the first insertion groove (310) formed in one of the first connecting portions (300) is inserted into the first insertion groove (310) formed in the other first connecting portion (300), and when the first insertion grooves (310) of each of the two first connecting portions (300) are inserted, the first insertion protrusions (320) formed on both sides based on the inserted first insertion grooves (310) can alternately overlap each other vertically.

Through the connection method of the first insertion groove (310) and the first insertion projection (320), the patient can simply connect the first connecting portions (300) to each other. The first connecting portion (300) is connected through the connection method of the first insertion groove (310) and the first insertion projection (320) without including Velcro, so that the fastening force of the connecting portion may not decrease even if the heel protector (10) is used repeatedly. In addition, the first connecting portion (300) does not include a relatively complex connecting structure such as a buckle or belt or a hard material such as a metal material, so that the patient's skin may not be compressed even if the patient wears the heel protector (10) for a long time. In addition, since the first connecting portion (300) extends from the cover portion (200) that supports the patient's heel (H) and is fastened near the instep, a connecting member such as a belt or buckle is not inserted into the inside of the cover portion (200), so that the patient's skin can be prevented from being compressed by the first connecting portion (300).

The second connecting portion (400) can support the heel protector (10) so that it does not come off from the patient's body while the patient is wearing the heel protector (10). For example, the second connecting portion (400) can be located near the lower part of the patient's knee and connected near the shin (S). As shown in FIGS. 1 and 2, the second connecting portion (400) includes two second connecting portions (400), and the two second connecting portions (400) can be connected to each of the upper sides of the main body (100). The patient can connect the two second connecting portions (400) to each other while wearing the heel protector (10). The two second connecting portions (400) can be connected above the patient's shin (S). Alternatively, there can be one or three or more second connecting portions (400). Alternatively, the second connecting portion (400) may include an even number of second connecting portions (400). For example, two second connecting portions (400) may extend from one side of the main body (100) and the other two second connecting portions (400) may extend from the other side of the main body (100). The second connecting portions (400) may be connected to each other in pairs of two.

The second connecting portion (400) may include a second insertion groove (410) and a second insertion protrusion (420).

A plurality of second insertion grooves (410) are arranged along the longitudinal direction of the second connecting portion (400), and may be formed by partially cutting the second connecting portion (400) in the width direction. The plurality of second insertion grooves (410) may be spaced apart from each other along the longitudinal direction of the second connecting portion (400). In FIG. 1, eight second insertion grooves (410) are shown formed in the second connecting portion (400), but the number of second insertion grooves (410) may be appropriately selected in consideration of the patient's body type, etc. The number of second insertion grooves (410) may be eight or more. Alternatively, the number of second insertion grooves (410) may be eight or less. The plurality of second insertion grooves (410) formed in one second connecting portion (400) may be formed in a different direction from the plurality of second insertion grooves (410) formed in another second connecting portion (400). For example, as shown in Fig. 1, when there are two second connecting portions (400), a plurality of second insertion grooves (410) formed in one second connecting portion (400) can extend downward from the upper end of the second connecting portion (400) in the width direction of the second connecting portion (400). And a plurality of second insertion grooves (410) formed in another second connecting portion (400) can extend upward from the lower end of the second connecting portion (400) in the width direction of the second connecting portion (400). That is, the second connecting portion (400) includes a plurality of second connecting portions (400), and the plurality of second connecting portions (400) are connected to each other in pairs of two, and a plurality of second insertion grooves (410) formed in one of the two second connecting portions (400) connected to each other can extend in one direction from the upper end of the corresponding second connecting portion (400), and a plurality of second insertion grooves (410) formed in the other can extend in one direction from the lower end of the corresponding second connecting portion (400). Therefore, when a patient connects the second insertion grooves (410) formed in the two second connecting portions (400) to each other, the two second connecting portions (400) can be connected from above and below so that the second insertion grooves (410) are naturally inserted into each other. The second insertion grooves (410) can be formed deeper than half the width of the second connecting portion (400). Accordingly, the second insertion grooves (410) can be inserted deeply into each other so that the second connecting portions (400) can be reliably connected. In addition, the second insertion grooves (410) can have a shape in which the width gradually narrows along the direction extending from the end. Therefore, the second insertion grooves (410) can be prevented from easily coming off while being inserted into each other. Since a plurality of second insertion grooves (410) are formed, the patient can adjust the connection position considering the size of his or her foot or discomfort. Alternatively, although the second insertion grooves (410) are shown as having a predetermined width in FIG. 1, etc., the second insertion grooves (410) can have a slit shape. That is, the second insertion grooves (410) can be formed in a line shape.

The second insertion projection (420) is located between the second insertion grooves (410) and can be formed with a wider width than the second insertion grooves (410). When the second insertion groove (410) formed in one second connecting portion (400) is inserted into the second insertion groove (410) formed in another second connecting portion (400), the second insertion projections (420) formed in each of the second connecting portions (400) overlap each other to firmly support the connection between the second connecting portions (400). For example, when two second insertion grooves (410) are inserted into each other, one of the two second insertion protrusions (420) formed in one second connecting portion (400) is above one second insertion protrusion (420) of the other second connecting portion (400), and the other is below one second insertion protrusion (420) of the other second connecting portion (400). That is, when the two second connecting portions (400) are connected to each other, each of the second insertion protrusions (420) intersects with respect to the second connecting portion (400). The connection method of the second insertion groove (410) and the second insertion protrusion (420) may be the same as the connection method of the first insertion groove (310) and the first insertion protrusion (320). For example, the second connecting portion (400) includes two second connecting portions (400), and the two second connecting portions (400) extend from one side and the other side of the main body (100), respectively, and the second insertion groove (410) formed in one of the second connecting portions (400) is inserted into the second insertion groove (410) formed in the other second connecting portion (400), and when the second insertion grooves (410) of each of the two second connecting portions (400) are inserted, the second insertion protrusions (420) formed on both sides based on the inserted second insertion grooves (410) can alternately overlap each other vertically.

Through the connection method of the second insertion groove (410) and the second insertion projection (420), the patient can simply connect the second connecting portions (400) to each other. The second connecting portion (400) is connected through the connection method of the second insertion groove (410) and the second insertion projection (420) without including Velcro, so that the fastening force of the connecting portion may not decrease even if the heel protector (10) is used repeatedly. In addition, the second connecting portion (400) does not include a relatively complex connecting structure such as a buckle or belt or a hard material such as a metal material, so that the patient's skin may not be compressed even if the patient wears the heel protector (10) for a long time. In addition, since the second connecting portion (400) extends from the cover portion (200) that supports the patient's heel (H) and is fastened near the instep, a connecting member such as a belt or buckle is not inserted into the inside of the cover portion (200), so that the patient's skin can be prevented from being compressed by the second connecting portion (400).

The heel protector (10) covers only the minimum body parts required for fixation, so that discomfort or pressure can be minimized even if the patient wears the heel protector (10) for a long period of time. For example, as shown in FIG. 2, when the patient wears the heel protector (10), the first connecting part (300) covers only a part of the patient's instep, and the second connecting part (400) covers only a part of the patient's shin (S). That is, when the first connecting part (300) and the second connecting part (400) are each connected, the patient's foot (F) may be exposed through the space between the first connecting part (300) and the second connecting part (400). Therefore, the patient's lower body may be exposed except for the heel (H) to prevent bedsores, a part of the calf (C), a part of the instep, and a part of the shin (S). Therefore, the heel protector (10) not only has excellent ventilation, but also allows medical staff to easily observe the patient's lower body condition with the naked eye, and minimizes factors that may cause discomfort or pressure to the patient's body.

Fig. 5 shows a heel protector (10A) according to another embodiment, and Figs. 6 to 8 show a first fastening groove (220A) and a fastening member (500A). Parts not shown in the drawings of the heel protector (10A) according to the present embodiment will be described by referring to the drawings of the heel protector (10) according to the above-described embodiment.

The heel protector (10A) is a medical auxiliary device for protecting and supporting the heel of a patient, and can prevent bedsores from forming on the heel of a patient who is bedridden for a long time due to the heel being pressed against the bed. When a patient wears the heel protector (10A), the heel protector (10A) can be positioned on the heel, sole, shin, and calf of the patient. The heel protector (10A) can be made of a material suitable for medical use that does not cause rashes on the skin even when worn for a long time. For example, the heel protector (10A) can include at least a portion of natural rubber or chloroprene rubber, TPU, TPE, etc. In addition, the heel protector (10A) can include various medical materials. In addition, the heel protector (10A) can be made of a deformable elastic material. The heel protector (10A) can be made of an integral part or can be made of different separate components combined together.

The heel guard (10A) may include a main body (100A), a cover part (200A), a first connecting part (300A), a second connecting part (400A), and a fastening member (500A). At least one of the main body (100A), the cover part (200A), the first connecting part (300A), and the second connecting part (400A) may include a plurality of ventilation holes.

A heel protector (10A) according to one or more embodiments comprises a main body (100A) corresponding to a patient's calf, a cover part (200A) having a plurality of first fastening grooves (220A) which are concavely formed on the inside so that the patient's heel can be inserted and which include one or more curved portions and one or more straight portions, a plurality of first insertion grooves (310A) extending from the cover part (200A) in a longitudinal direction and a plurality of first insertion protrusions (320A) formed between the plurality of first insertion grooves (310A), and a plurality of first connecting parts (300A) which are paired and connected near the patient's instep, a plurality of second insertion grooves (410A) extending from the main body (100A) in a longitudinal direction, a plurality of second insertion protrusions (420A) formed between the plurality of second insertion grooves (410A), and a plurality of second insertion protrusions (420A) including one or more curved portions and one or more straight portions. The invention relates to a brace for a patient's shin, comprising: a pair of second fastening grooves (440A); a second connecting portion (400A) that is connected in pairs near the patient's shin; a first fastening groove (220A) having one end inserted into one of a plurality of first fastening grooves (220A) and the other end inserted into the other first fastening groove (220A) so as to connect the two first fastening grooves (220A) to each other, and elastically supporting the first connecting portion (300A); and a fastening member (500A) having one end inserted into one of a plurality of second fastening grooves (440A) and the other end inserted into the other second fastening groove (440A) so as to connect the two second fastening grooves (440A) to each other, and elastically supporting the second connecting portion (400A).

The main body (100A) can support and connect the cover part (200A), the first connection part (300A), and the second connection part (400A). The main body (100A) can have a long shape in one direction so that it can support the calf (C) while the patient wears the heel protector (10A). For example, as shown in Fig. 5, the main body (100A) can have one end connected to the cover part (200A) in the length direction, and two second connection parts (400A) can be positioned on both sides in the width direction. The main body (100A) can support from the back of the patient's ankle to a part of the calf (C) and can be made of an elastic material that can be deformed to fit the shape of the patient's body.

The main body (100A) may include a first ventilation hole (110A).

As shown in Fig. 5, a plurality of first ventilation holes (110A) may be formed in the main body (100A). The first ventilation holes (110A) can prevent sweat or moisture from accumulating in the calf (C) while the patient is wearing the heel protector (10A). The number, shape, and size of the first ventilation holes (110A) are not particularly limited.

The cover part (200A) is supported on the main body part (100A) and can wrap around the heel (H) while the patient is wearing the heel protector (10A), distribute the load applied to the heel (H), and prevent bedsores from occurring on the heel (H). For example, the cover part (200A) can have an inwardly concave shape to wrap around the heel (H) while the patient is wearing the heel protector (10A). The cover part (200A) can support the heel (H), a part of the sole, the peach bone, and the Achilles tendon. At least a part of the cover part (200A) can be made of a material that is thicker and softer than other parts of the heel protector (10A). For example, one or more layers can be added to the inner side of the cover part (200A). The above layer may be made of the same material as the main body (100A), the cover (200A), the first connecting portion (300A), and the second connecting portion (400A), or may be made of a different material. For example, the above layer may be one or more of memory foam, latex, polyester, bead/bio material, cotton, and sponge. Alternatively, the above layer may include an air layer or a fluid layer.

The cover portion (200A) may include a second ventilation hole (210A).

As shown in Fig. 5, a plurality of second ventilation holes (210A) may be formed in the cover portion (200A). The second ventilation holes (210A) can prevent sweat or moisture from accumulating on the heel (H) of a patient wearing a heel protector (10A). The number, shape, and size of the second ventilation holes (210A) are not particularly limited.

The cover part (200A) may include a first fastening groove (220A).

The first fastening grooves (220A) may be formed in multiple numbers in the cover portion (200A) so that the fastening member (500A) may be inserted therein. For example, as shown in FIG. 5, the first fastening grooves (220A) may be formed symmetrically with respect to the center in the width direction of the cover portion (200A). The first fastening grooves (220A) may be formed in total of four, two each on one side and the other side based on the second ventilation hole (210A). Alternatively, the first fastening grooves (220A) may be formed in multiple numbers or more than four. Alternatively, the first fastening grooves (220A) may be formed in multiple numbers in the length direction of the cover portion (200A). Two first fastening grooves (220A) formed symmetrically with respect to the center in the width direction of the cover portion (200A) may be connected to each other as a pair. A plurality of fastening grooves formed in the cover portion (200A) are formed on one side and the other side as first fastening grooves (220A) so as to be symmetrical with respect to the center in the width direction of the cover portion (200A), and the fastening member (500A) can be inserted into one first fastening groove (220A) with one side inserted into it and the other side inserted into another first fastening groove (220A) to elastically support the first connecting portion (300A) from above.

The first fastening home (220A) may include a first part (221A), a second part (222A), a third part (223A), a fourth part (224A), a fifth part (225A), and a fixing hole (226A).

The first part (221A) has a curved portion, and a fastening member (500A) can be inserted into an end of the first part (221A). For example, the first part (221A) can be circular or oval. Since the first part (221A) has a curved portion, the fastening member (500A) inserted into the first fastening groove (220A) can be prevented from being easily detached.

The second portion (222A) may extend from an end of the first portion (221A) and may have a straight portion. After the patient inserts the fastening member (500A) into the first portion (221A), the patient may move both sides of the fastening member (500A) to the two second portions (222A), respectively.

The third portion (223A) may extend from each end of the second portion (222A) and may have a straight portion. The third portion (223A) may extend in a direction intersecting the direction in which the second portion (222A) extends. The patient may move each of the two sides of the fastening member (500A) located in the second portion (222A) to the two third portions (223A).

The fourth portion (224A) may extend from each end of the third portion (223A) and may have a straight portion. The fourth portion (224A) may extend in a direction intersecting the direction in which the third portion (223A) extends. The patient may move each of the two fourth portions (224A) on both sides of the fastening member (500A) located at the third portion (223A).

The fifth portion (225A) may extend from each end of the fourth portion (224A) and may have a straight portion. The fifth portion (225A) may extend in a direction intersecting the direction in which the fourth portion (224A) extends. The patient may move each of the two fifth portions (225A) on both sides of the fastening member (500A) located at the fourth portion (224A).

The anchoring holes (226A) may be formed at each end of the two fifth sections (225A). The patient may move each side of the fastening member (500A) located at the fifth section (225A) to the two anchoring holes (226A). The anchoring holes (226A) may be the positions where the fastening member (500A) is finally anchored.

The first part (221A), the second part (222A), the third part (223A), the fourth part (224A), the fifth part (225A) and the anchoring hole (226A) can all be formed continuously. The first part (221A), the second part (222A), the third part (223A), the fourth part (224A), and the fifth part (225A) can have a predetermined width or be formed in a linear shape.

In this way, the first fastening groove (220A) may have a shape including a curved portion and a straight portion, and a first portion (221A), a second portion (222A), a third portion (223A), a fourth portion (224A), and a fifth portion (225A) that intersect in different directions. Accordingly, even if a patient wears the heel protector (10A) for a long time, the fastening member (500A) may not easily move or come off from the first fastening groove (220A).

The first connecting portion (300A) can support the heel protector (10A) so that it does not come off from the patient's body while the patient is wearing the heel protector (10A). For example, the first connecting portion (300A) can be connected at the instep portion passing the patient's foot (F). As shown in FIG. 5, the first connecting portion (300A) includes two first connecting portions (300A), and the two first connecting portions (300A) can be connected to each of both sides of the cover portion (200A). The patient can connect the two first connecting portions (300A) to each other while wearing the heel protector (10A). The two first connecting portions (300A) can be connected on the instep of the patient. Alternatively, there can be one or three or more first connecting portions (300A). Alternatively, the first connecting portion (300A) may include an even number of first connecting portions (300A). For example, two first connecting portions (300A) may extend from one side of the cover portion (200A) and the other two first connecting portions (300A) may extend from the other side of the cover portion (200A). The first connecting portions (300A) may be connected to each other in pairs of two.

The first connecting portion (300A) may include a first insertion groove (310A) and a first insertion projection (320A).

A plurality of first insertion grooves (310A) are arranged along the length direction of the first connecting portion (300A), and may be formed by partially cutting the first connecting portion (300A) in the width direction. The plurality of first insertion grooves (310A) may be spaced apart from each other along the length direction of the first connecting portion (300A). In Fig. 1, four first insertion grooves (310A) are shown formed in the first connecting portion (300A), but the number of first insertion grooves (310A) may be appropriately selected in consideration of the patient's body type, etc. The number of first insertion grooves (310A) may be four or more, as shown in Fig. 5. Alternatively, the number of first insertion grooves (310A) may be four or less. The plurality of first insertion grooves (310A) formed in one first connecting portion (300A) may be formed in a different direction from the plurality of first insertion grooves (310A) formed in another first connecting portion (300A). For example, as shown in FIG. 5, when there are two first connecting portions (300A), the plurality of first insertion grooves (310A) formed in one first connecting portion (300A) may extend downward in the width direction of the first connecting portion (300A) from the upper end of the first connecting portion (300A). And the plurality of first insertion grooves (310A) formed in another first connecting portion (300A) may extend upward in the width direction of the first connecting portion (300A) from the lower end of the first connecting portion (300A). Therefore, as shown in Fig. 5, when a patient connects the first insertion grooves (310A) formed in the two first connecting portions (300A) to each other, the two first connecting portions (300A) can be connected from above and below so that the first insertion grooves (310A) are naturally inserted into each other. The first insertion grooves (310A) can be formed deeper than half the width of the first connecting portion (300A). Therefore, the first insertion grooves (310A) can be inserted deeply into each other so that the first connecting portions (300A) can be reliably connected. In addition, the first insertion grooves (310A) can have a shape in which the width gradually narrows along the direction extending from the end. Therefore, the first insertion grooves (310A) can be prevented from easily coming off when inserted into each other. Since a plurality of first insertion grooves (310A) are formed, the patient can adjust the connection position considering the size of his or her foot or discomfort. Alternatively, although the first insertion groove (310A) is shown as having a predetermined width in Fig. 1, the first insertion groove (310A) may have a slit shape. That is, the first insertion groove (310A) may have a line shape.

The first insertion projection (320A) is located between the first insertion grooves (310A) and can be formed with a wider width than the first insertion grooves (310A). When the first insertion groove (310A) formed in one first connecting portion (300A) is inserted into the first insertion groove (310A) formed in another first connecting portion (300A), the first insertion projections (320A) formed in each of the first connecting portions (300A) overlap each other to firmly support the connection between the first connecting portions (300A). For example, when two first insertion grooves (310A) are inserted into each other, one of the two first insertion protrusions (320A) formed in one first connecting portion (300A) is above one first insertion protrusion (320A) of the other first connecting portion (300A), and the other is below one first insertion protrusion (320A) of the other first connecting portion (300A). That is, when the two first connecting portions (300A) are connected to each other, the first insertion protrusions (320A) intersect each other with respect to the first connecting portion (300A). In Fig. 4, the dotted lines indicate the ends of the first insertion protrusions (320A) respectively located below.

Through this method of connecting the first insertion groove (310A) and the first insertion projection (320A), the patient can simply connect the first connecting portion (300A) to each other. The first connecting portion (300A) is connected through the method of connecting the first insertion groove (310A) and the first insertion projection (320A) without including Velcro, so that the fastening force of the connecting portion may not decrease even if the heel protector (10A) is used repeatedly. In addition, the first connecting portion (300A) does not include a relatively complex connecting structure such as a buckle or belt, or a hard material such as a metal material, so that the patient's skin may not be compressed even if heel protector (10A) is worn for a long time. In addition, since the first connecting portion (300A) extends from the cover portion (200) that supports the patient's heel (H) and is fastened near the instep, a connecting member such as a belt or buckle is not inserted into the inside of the cover portion (200), thereby preventing the patient's skin from being compressed by the first connecting portion (300A).

The first connecting portion (300A) may include a third ventilation hole (330A).

As shown in Fig. 5, a plurality of third ventilation holes (330A) may be formed in the first connecting portion (300A). The third ventilation holes (330A) can prevent sweat or moisture, etc., from accumulating on the heel (H) of a patient wearing a heel protector (10A). The number, shape, and size of the third ventilation holes (330A) are not particularly limited. The third ventilation holes (330A) may be formed so as not to overlap with the first insertion groove (310A) in the width direction and length direction of the first connecting portion (300A). If the third ventilation holes (330A) are formed so as to overlap with the first insertion groove (310A), the area cut off in the width direction and length direction of the first connecting portion (300A) increases, which may reduce the strength of the first connecting portion (300A). Therefore, the durability of the first connecting portion (300A) can be secured through such a configuration.

The second connecting portion (400A) can support the heel protector (10A) so that it does not come off from the patient's body while the patient is wearing the heel protector (10A). For example, the second connecting portion (400A) can be located near the lower part of the patient's knee and connected near the shin (S). As shown in FIG. 5, there are two second connecting portions (400A) and they can be connected to each of the upper sides of the main body (100). The patient can connect the two second connecting portions (400A) to each other while wearing the heel protector (10A). The two second connecting portions (400A) can be connected above the patient's shin (S). Alternatively, the number of second connecting portions (400A) can be one or three or more. Alternatively, the second connecting portions (400A) can include an even number of second connecting portions (400A). For example, two second connecting portions (400A) may extend from one side of the main body (100) and two other second connecting portions (400A) may extend from the other side of the main body (100). The second connecting portions (400A) may be connected to each other in pairs.

The second connecting portion (400A) may include a second insertion groove (410A) and a second insertion projection (420A).

A plurality of second insertion grooves (410A) are arranged along the length direction of the second connecting portion (400A), and may be formed by partially cutting the second connecting portion (400A) in the width direction. The plurality of second insertion grooves (410A) may be spaced apart from each other along the length direction of the second connecting portion (400A). In Fig. 1, eight second insertion grooves (410A) are shown formed in the second connecting portion (400A), but the number of second insertion grooves (410A) may be appropriately selected in consideration of the patient's body type, etc. The number of second insertion grooves (410A) may be eight or more. Alternatively, the number of second insertion grooves (410A) may be eight or less. The plurality of second insertion grooves (410A) formed in one second connecting portion (400A) may be formed in a different direction from the plurality of second insertion grooves (410A) formed in the other second connecting portion (400A). For example, as shown in FIG. 5, when there are two second connecting portions (400A), the plurality of second insertion grooves (410A) formed in one second connecting portion (400A) may extend downward in the width direction of the second connecting portion (400A) from the upper end of the second connecting portion (400A). And the plurality of second insertion grooves (410A) formed in the other second connecting portion (400A) may extend upward in the width direction of the second connecting portion (400A) from the lower end of the second connecting portion (400A). Therefore, when the patient connects the second insertion grooves (410A) formed in the two second connecting portions (400A) to each other, the two second connecting portions (400A) can be connected from above and below so that the second insertion grooves (410A) are naturally inserted into each other. The second insertion grooves (410A) can be formed deeper than half the width of the second connecting portion (400A). Therefore, the second insertion grooves (410A) can be inserted deeply into each other so that the second connecting portions (400A) can be reliably connected. In addition, the second insertion grooves (410A) can have a shape in which the width gradually narrows along the direction extending from the end. Therefore, the second insertion grooves (410A) can be prevented from easily coming off when inserted into each other. Since a plurality of second insertion grooves (410A) are formed, the patient can adjust the connection position considering the size of his or her foot or discomfort. Alternatively, although the second insertion groove (410A) is shown as having a predetermined width in Fig. 1, the second insertion groove (410A) may have a slit shape. That is, the second insertion groove (410A) may be formed in a line shape.

The second insertion projection (420A) is located between the second insertion grooves (410A) and can be formed with a wider width than the second insertion grooves (410A). When the second insertion groove (410A) formed in one second connecting portion (400A) is inserted into the second insertion groove (410A) formed in another second connecting portion (400A), the second insertion projections (420A) formed in each of the second connecting portions (400A) overlap each other to firmly support the connection between the second connecting portions (400A). For example, when two second insertion grooves (410A) are inserted into each other, one of the two second insertion protrusions (420A) formed in one second connecting portion (400A) is above one second insertion protrusion (420A) of the other second connecting portion (400A), and the other is below one second insertion protrusion (420A) of the other second connecting portion (400A). That is, when the two second connecting portions (400A) are connected to each other, each of the second insertion protrusions (420A) intersects with respect to the second connecting portion (400A). The connection method of the second insertion groove (410A) and the second insertion protrusion (420A) may be the same as the connection method of the first insertion groove (310A) and the first insertion protrusion (320A).

Through this method of connecting the second insertion groove (410A) and the second insertion projection (420A), the patient can easily connect the second connecting portions (400A) to each other. The second connecting portion (400A) is connected through the method of connecting the second insertion groove (410A) and the second insertion projection (420A) without including Velcro, so that the fastening force of the connecting portion may not decrease even if the heel protector (10A) is used repeatedly. In addition, the second connecting portion (400A) does not include a relatively complex connecting structure such as a buckle or belt, or a hard material such as a metal material, so that the patient's skin may not be compressed even if heel protector (10A) is worn for a long time. In addition, since the second connecting portion (400A) extends from the cover portion (200) that supports the patient's heel (H) and is fastened near the instep, a connecting member such as a belt or buckle is not inserted into the inside of the cover portion (200), thereby preventing the patient's skin from being compressed by the second connecting portion (400A).

The second connecting portion (400A) may include a fourth ventilation hole (430A).

As shown in Fig. 5, a plurality of fourth ventilation holes (430A) may be formed in the second connecting portion (400A). The fourth ventilation holes (430A) can prevent sweat or moisture, etc., from accumulating on the heel (H) of a patient wearing a heel protector (10A). The number, shape, and size of the fourth ventilation holes (430A) are not particularly limited. The fourth ventilation holes (430A) may be formed so as not to overlap with the second insertion groove (410A) in the width direction and length direction of the second connecting portion (400A). If the fourth ventilation holes (430A) are formed so as to overlap with the second insertion groove (410A), the cut-off area in the width direction and length direction of the second connecting portion (400A) increases, which may reduce the strength of the second connecting portion (400A). Therefore, the durability of the second connecting portion (400A) can be secured through such a configuration.

The second connecting portion (400A) may include a second fastening groove (440A).

A plurality of second fastening grooves (440A) are formed in the second connecting portion (400A) so that a fastening member (500A) can be inserted therein. For example, as shown in FIG. 5, a plurality of second fastening grooves (440A) can be formed longitudinally inward from a plurality of second insertion grooves (410A), second insertion protrusions (420A), and fourth ventilation holes (430A) formed in the second connecting portion (400A). For example, three second fastening grooves (440A) can be formed in one second connecting portion (400A). Alternatively, three or fewer or three or more second fastening grooves (440A) can be formed in one second connecting portion (400A). The shape of the second fastening groove (440A) and the insertion method of the fastening member (500A) are the same as those of the first fastening groove (220A), and their description is omitted. The plurality of fastening grooves formed in the second connecting portion (400A) are formed on the inner side of the plurality of second insertion grooves (410A) in the longitudinal direction of the second connecting portion (400A) as second fastening grooves (440A), and the fastening member (500A) can elastically support the second connecting portion (400A) by inserting one side into one of the second fastening grooves (440A) and the other side into another second fastening groove (440A). In addition to the connection between the second insertion groove (410A) and the second insertion projection (420A), the connection between the second fastening groove (440A) and the fastening member (500A) can more firmly maintain the connection of the second connecting portion (400A).

The fastening member (500A) can connect the first fastening grooves (220A) to each other. The fastening member (500A) is made of a deformable elastic material, and may be, for example, rubber. The fastening member (500A) may have a closed contour. As shown in FIG. 6, the patient inserts the fastening member (500A) into the first part (221A) formed in one of the first fastening grooves (220A), and then spreads both sides of the fastening member (500A) and moves it along the first part (221A) to two second parts (222A). Thereafter, the patient can sequentially move the both sides of the fastening member (500A) to the third part (223A), the fourth part (224A), and the fifth part (225A), and then settle it into the two fixing holes (226A). The next patient can secure the fastening member (500A) in the two fixing holes (226A) formed in another first fastening groove (220A) in the same manner. Here, the other first fastening groove (220A) may be a first fastening groove (220A) that is positioned symmetrically with respect to the center of the first fastening groove (220A) that was inserted first and the cover part (200A). Therefore, as shown in Fig. 7, one fastening member (500A) can connect the two first fastening grooves (220A) to each other, and the connected state is as shown in Fig. 8. Therefore, in a state where the two first connecting members (300A) are connected, the fastening member (500A) can pull both ends of the cover part (200A) so that the cover part (200A) can be in close contact with the patient's heel (H). In addition, the fastening member (500A) can be pressed against the two first connecting portions (300A) toward the patient's instep, thereby allowing the first connecting portions (300A) to maintain a close connection state.

The method by which the fastening member (500A) connects the second fastening grooves (440A) to each other may be the same as the method by which the first fastening grooves (220A) are connected, and a description thereof will be omitted. That is, when the two second connecting portions (400A) are connected to each other, the fastening member (500A) may press the two second connecting portions (400A) toward the patient's shin (S), so that the second connecting portions (400A) may maintain a close connection state.

The heel protector (10A) covers only the minimum body parts necessary for fixation, so that discomfort or pressure can be minimized even if the patient wears the heel protector (10A) for a long time. For example, when the patient wears the heel protector (10A), the first connecting part (300A) covers only a part of the patient's instep, and the second connecting part (400A) covers only a part of the patient's shin (S). Therefore, the patient's lower body may be exposed except for the heel (H) part, a part of the calf (C), a part of the instep, and a part of the shin (S) to prevent bedsores. Therefore, the heel protector (10A) not only has excellent ventilation, but also allows medical staff to easily observe the condition of the patient's lower body with the naked eye, and minimizes factors that may cause discomfort or pressure to the patient's body. In addition, the heel protector includes a first ventilation hole (110A), a second ventilation hole (210A), a third ventilation hole (330A), and a fourth ventilation hole (430A), thereby preventing moisture or sweat from accumulating even when the patient wears the heel protector (10A) for a long time. In addition, the heel protector includes a first fastening groove (220A), a second fastening groove (440A), and a fastening member (500A), thereby allowing the heel protector (10A) to adhere closely to the patient's body, and allowing the first connecting portion (300A) and the second connecting portion (400A) to be firmly connected.

Fig. 9 shows a first fastening home (220B) according to another embodiment.

The first fastening home (220B) may include a first portion (221B), a second portion (222B), a third portion (223B), and a fixing hole (224B).

The first part (221B) has a curved portion, and a fastening member (500B) can be inserted into an end of the first part (221B). For example, the first part (221B) can be circular or oval. Since the first part (221B) has a curved portion, the fastening member (500B) inserted into the first fastening groove (220B) can be prevented from being easily detached. For example, the first part (221B) has a shape that is much longer in the width direction than the first part (221A), and thus the fastening member (500B) can be more reliably prevented from being detached.

The second portion (222B) may extend from each end of the first portion (221B) and may have a curved portion. The second portion (222B) may have a curvature in the opposite direction to the portion extending from the first portion (221B). After the patient inserts the fastening member (500B) into the first portion (221B), the patient may move both sides of the fastening member (500B) to the two second portions (222B), respectively.

The third portion (223B) may extend from each end of the second portion (222B) and may have a straight portion. The third portion (223B) may extend in a direction intersecting the direction in which the second portion (222B) extends. The patient may move each of the two third portions (223B) on both sides of the fastening member (500B) located in the second portion (222B).

The anchoring holes (224B) may be formed at each end of the two third parts (223B). The patient may move both sides of the fastening member (500B) located at the third part (223B) to the two anchoring holes (224B). The anchoring holes (224B) may be the positions where the fastening member (500B) is finally anchored.

The first part (221B), the second part (222B), the third part (223B), and the anchoring hole (224B) can all be formed continuously. The first part (221B), the second part (222B), and the third part (223B) can have a predetermined width or be formed in a linear shape.

In this way, the first fastening groove (220B) may have a shape including a curved portion and a straight portion, and a first portion (221B), a second portion (222B), and a third portion (223B) that intersect in different directions. Accordingly, even if a patient wears the heel protector (10B) for a long period of time, the fastening member (500B) may not easily move or come off from the first fastening groove (220B).

Although only the first fastening groove (220B) is shown in Fig. 9, the second fastening groove may also have the same shape as the first fastening groove (220B).

Fig. 10 shows a heel guard (10C) according to another embodiment.

The heel protector (10C) is a medical auxiliary device for protecting and supporting the heel of a patient, and can prevent bedsores from forming on the heel of a patient who is bedridden for a long time due to the heel being pressed against the bed. When a patient wears the heel protector (10C), the heel protector (10C) can be positioned on the patient's heel, sole, shin, and calf. The heel protector (10C) can be made of a material suitable for medical use that does not cause rashes on the skin even when worn for a long time. For example, the heel protector (10C) can include at least a portion of natural rubber or chloroprene rubber, TPU, TPE, etc. In addition, the heel protector (10C) can include various medical materials. In addition, the heel protector (10C) can be made of a deformable elastic material. The heel protector (10C) can be made of an integral part or can be made of different separate components combined together.

The heel protector (10C) may include a main body (100C), a cover portion (200C), a first connecting portion (300C), a second connecting portion (400C), and a fastening member (not shown in the drawing). At least one of the cover portion (200C), the first connecting portion (300C), and the second connecting portion (400C) may include a plurality of fastening grooves, and the heel protector (10C) may further include a fastening member connecting the plurality of fastening grooves. The fastening member may be the same as the fastening member (500A) according to the above-described embodiment. The plurality of fastening grooves include at least one straight portion and at least one curved portion, and one side of the fastening member may be inserted into one of the fastening grooves and the other side may be inserted into the other of the fastening grooves.

The main body (100C) can support and connect the cover part (200C), the first connection part (300C), and the second connection part (400C). The main body (100C) can have a long shape in one direction so that it can support the calf (C) while the patient wears the heel protector (10C). For example, as shown in Fig. 10, the main body (100C) can have one end connected to the cover part (200C) in the length direction, and two second connection parts (400C) can be positioned on both sides in the width direction. The main body (100C) can support from the back of the patient's ankle to a part of the calf (C) and can be made of an elastic material that can be deformed to fit the shape of the patient's body.

The main body (100C) may include a first ventilation hole (110C).

As shown in Fig. 10, a plurality of first ventilation holes (110C) may be formed in the main body (100C). The first ventilation holes (110C) can prevent sweat or moisture from accumulating in the calf (C) while the patient is wearing the heel protector (10C). The number, shape, and size of the first ventilation holes (110C) are not particularly limited.

The cover part (200C) is supported on the main body part (100C) and can wrap around the heel (H) while the patient is wearing the heel protector (10C), distribute the load applied to the heel (H), and prevent bedsores from occurring on the heel (H). For example, the cover part (200C) can have an inwardly concave shape to wrap around the heel (H) while the patient is wearing the heel protector (10C). The cover part (200C) can support the heel (H), a part of the sole, the peach bone, and the Achilles tendon. At least a part of the cover part (200C) can be made of a material that is thicker and softer than other parts of the heel protector (10C). For example, one or more layers can be added to the inner side of the cover part (200C). The above layer may be made of the same material as the main body (100C), the cover (200C), the first connecting portion (300C), and the second connecting portion (400C), or may be made of a different material. For example, the layer may be one or more of memory foam, latex, polyester, bead/bio material, cotton, and sponge. Alternatively, the layer may include an air layer or a fluid layer.

The cover part (200C) may include a second ventilation hole (210C).

As shown in Fig. 10, a plurality of second ventilation holes (210C) may be formed in the cover portion (200C). The second ventilation holes (210C) can prevent sweat or moisture from accumulating on the heel (H) of a patient wearing a heel protector (10C). The number, shape, and size of the second ventilation holes (210C) are not particularly limited.

The cover part (200C) may include a first fastening groove (220C).

The first fastening grooves (220C) may be formed in multiple numbers in the cover portion (200C) so that fastening members may be inserted therein. For example, as shown in FIG. 10, the first fastening grooves (220C) may be formed symmetrically with respect to the center in the width direction of the cover portion (200C). The first fastening grooves (220C) may be formed in total of four, two each on one side and the other side based on the second ventilation hole (210C). Alternatively, the first fastening grooves (220C) may be formed in multiple numbers or more than four. Alternatively, the first fastening grooves (220C) may also be formed in multiple numbers in the length direction of the cover portion (200C). Two first fastening grooves (220C) formed symmetrically with respect to the center in the width direction of the cover portion (200C) may be connected to each other as a pair. The shape of the first fastening groove (220C) and the insertion method of the fastening member are the same as those of the first fastening groove (220A) described above, and a description thereof is omitted. Accordingly, even if the patient wears the heel protector (10C) for a long period of time, the fastening member may not easily move or come off from the first fastening groove (220C).

The first connecting portion (300C) can support the heel protector (10C) so that it does not come off from the patient's body while the patient is wearing the heel protector (10C). For example, the first connecting portion (300C) can be connected at the instep portion passing the patient's foot (F). As shown in FIG. 10, the first connecting portion (300C) includes two first connecting portions (300C), and the two first connecting portions (300C) can be connected to each of both sides of the cover portion (200C). The patient can connect the two first connecting portions (300C) to each other while wearing the heel protector (10C). The two first connecting portions (300C) can be connected on the instep of the patient. Alternatively, there can be one or three or more first connecting portions (300C). Alternatively, the first connecting portion (300C) may include an even number of first connecting portions (300C). For example, two first connecting portions (300C) may extend from one side of the cover portion (200C) and the other two first connecting portions (300C) may extend from the other side of the cover portion (200C). The first connecting portions (300C) may be connected to each other in pairs of two.

The first connecting portion (300C) may include a first insertion groove (310C) and a first insertion projection (320C).

A plurality of first insertion grooves (310C) are arranged along the longitudinal direction of the first connecting portion (300C), and may be formed by partially cutting the first connecting portion (300C) in the width direction. The plurality of first insertion grooves (310C) may be spaced apart from each other along the longitudinal direction of the first connecting portion (300C). Although FIG. 1 shows that four first insertion grooves (310C) are formed in the first connecting portion (300C), the number of first insertion grooves (310C) may be appropriately selected in consideration of the patient's body type, etc. The number of first insertion grooves (310C) may be four or more, as shown in FIG. 10. Alternatively, the number of first insertion grooves (310C) may be four or less. The plurality of first insertion grooves (310C) formed in one first connecting portion (300C) may be formed in a different direction from the plurality of first insertion grooves (310C) formed in another first connecting portion (300C). For example, as shown in FIG. 10, when there are two first connecting portions (300C), the plurality of first insertion grooves (310C) formed in one first connecting portion (300C) may extend downward in the width direction of the first connecting portion (300C) from the upper end of the first connecting portion (300C). And the plurality of first insertion grooves (310C) formed in another first connecting portion (300C) may extend upward in the width direction of the first connecting portion (300C) from the lower end of the first connecting portion (300C). Therefore, when the patient connects the first insertion grooves (310C) formed in the two first connecting portions (300C) to each other, the two first connecting portions (300C) can be connected from above and below so that the first insertion grooves (310C) are naturally inserted into each other. The first insertion grooves (310C) can be formed deeper than half the width of the first connecting portion (300C). Therefore, the first insertion grooves (310C) can be inserted deeply into each other so that the first connecting portions (300C) can be reliably connected. In addition, the first insertion grooves (310C) can have a shape in which the width gradually narrows along the direction extending from the end. Therefore, the first insertion grooves (310C) can be prevented from easily coming off when inserted into each other. Since a plurality of first insertion grooves (310C) are formed, the patient can adjust the connection position considering the size of his or her foot or discomfort. Alternatively, although the first insertion groove (310C) is shown in FIG. 10 as having a predetermined width, the first insertion groove (310C) may have a slit shape. That is, the first insertion groove (310C) may be formed in a line shape.

The first insertion projection (320C) is located between the first insertion grooves (310C) and can be formed with a wider width than the first insertion grooves (310C). When the first insertion groove (310C) formed in one first connecting portion (300C) is inserted into the first insertion groove (310C) formed in another first connecting portion (300C), the first insertion projections (320C) formed in each of the first connecting portions (300C) overlap each other to firmly support the connection between the first connecting portions (300C). For example, when two first insertion grooves (310C) are inserted into each other, one of the two first insertion protrusions (320C) formed in one first connecting portion (300C) is above one first insertion protrusion (320C) of the other first connecting portion (300C), and the other is below one first insertion protrusion (320C) of the other first connecting portion (300C). That is, when the two first connecting portions (300C) are connected to each other, the first insertion protrusions (320C) intersect each other with respect to the first connecting portion (300C). In Fig. 4, the dotted lines indicate the ends of the first insertion protrusions (320C) respectively located below.

Through this method of connecting the first insertion groove (310C) and the first insertion projection (320C), the patient can easily connect the first connecting portions (300C) to each other. The first connecting portion (300C) is connected through the method of connecting the first insertion groove (310C) and the first insertion projection (320C) without including Velcro, so that the fastening force of the connecting portion may not decrease even if the heel protector (10C) is used repeatedly. In addition, the first connecting portion (300C) does not include a relatively complex connecting structure such as a buckle or belt, or a hard material such as a metal material, so that the patient's skin may not be compressed even if heel protector (10C) is worn for a long time. In addition, since the first connecting portion (300C) extends from the cover portion (200) that supports the patient's heel (H) and is fastened near the instep, a connecting member such as a belt or buckle is not inserted into the inside of the cover portion (200), thereby preventing the patient's skin from being compressed by the first connecting portion (300C).

The first connecting portion (300C) may include a third ventilation hole (330C).

As shown in Fig. 10, a plurality of third ventilation holes (330C) may be formed in the first connecting portion (300C). The third ventilation holes (330C) can prevent sweat or moisture, etc., from accumulating on the heel (H) of a patient wearing a heel protector (10C). The number, shape, and size of the third ventilation holes (330C) are not particularly limited. The third ventilation holes (330C) may be formed so as not to overlap with the first insertion groove (310C) in the width direction and length direction of the first connecting portion (300C). If the third ventilation holes (330C) are formed so as to overlap with the first insertion groove (310C), the cut-off area in the width direction and length direction of the first connecting portion (300C) increases, which may reduce the strength of the first connecting portion (300C). Therefore, the durability of the first connecting portion (300C) can be secured through such a configuration.

The first connecting portion (300C) may include a third fastening groove (340C).

A plurality of third fastening grooves (340C) are formed in the first connecting portion (300C) so that a fastening member can be inserted therein. For example, a plurality of third fastening grooves (340C) may be formed longitudinally inward from a plurality of first insertion grooves (310C), first insertion protrusions (320C), and third ventilation holes (330C) formed in the first connecting portion (300C). For example, two third fastening grooves (340C) may be formed in one first connecting portion (300C). Alternatively, two or fewer or two or more third fastening grooves (340C) may be formed in one first connecting portion (300C). The shape of the third fastening groove (340C) and the insertion method of the fastening member are the same as those of the first fastening groove (220C), and a description thereof will be omitted. A plurality of fastening grooves formed in the first connecting portion (300C) are formed as third fastening grooves (340C) on the inner side of a plurality of first insertion grooves (310C) in the longitudinal direction of the first connecting portion (300C), and a fastening member can elastically support the first connecting portion (300C) by having one side inserted into one of the third fastening grooves (340C) and the other side inserted into another third fastening groove (340C). In addition to the coupling between the first insertion groove (310C) and the first insertion projection (320C), the coupling between the second fastening groove (440A) and the fastening member (500A) can more firmly maintain the coupling of the second connecting portion (400A).

The second connecting portion (400C) can support the heel protector (10C) so that it does not come off from the patient's body while the patient is wearing the heel protector (10C). For example, the second connecting portion (400C) can be located near the lower part of the patient's knee and connected near the shin (S). There are two second connecting portions (400C) and they can be connected to each of the upper sides of the main body (100). The patient can connect the two second connecting portions (400C) to each other while wearing the heel protector (10C). The two second connecting portions (400C) can be connected above the patient's shin (S). Alternatively, the number of second connecting portions (400C) can be one or three or more. Alternatively, the second connecting portions (400C) can include an even number of second connecting portions (400C). For example, two second connecting portions (400C) may extend from one side of the main body (100) and two other second connecting portions (400C) may extend from the other side of the main body (100). The second connecting portions (400C) may be connected to each other in pairs.

The second connecting portion (400C) may include a second insertion groove (410C) and a second insertion projection (420C).

A plurality of second insertion grooves (410C) are arranged along the length direction of the second connecting portion (400C), and may be formed by partially cutting the second connecting portion (400C) in the width direction. The plurality of second insertion grooves (410C) may be spaced apart from each other along the length direction of the second connecting portion (400C). In Fig. 1, eight second insertion grooves (410C) are formed in the second connecting portion (400C), but the number of second insertion grooves (410C) may be appropriately selected in consideration of the patient's body type, etc. The number of second insertion grooves (410C) may be eight or more. Alternatively, the number of second insertion grooves (410C) may be eight or less. The plurality of second insertion grooves (410C) formed in one second connecting portion (400C) may be formed in a different direction from the plurality of second insertion grooves (410C) formed in the other second connecting portion (400C). For example, as shown in FIG. 10, when there are two second connecting portions (400C), the plurality of second insertion grooves (410C) formed in one second connecting portion (400C) may extend downward in the width direction of the second connecting portion (400C) from the upper end of the second connecting portion (400C). And the plurality of second insertion grooves (410C) formed in the other second connecting portion (400C) may extend upward in the width direction of the second connecting portion (400C) from the lower end of the second connecting portion (400C). Therefore, when the patient connects the second insertion grooves (410C) formed in the two second connecting portions (400C) to each other, the two second connecting portions (400C) can be connected from above and below so that the second insertion grooves (410C) are naturally inserted into each other. The second insertion grooves (410C) can be formed deeper than half the width of the second connecting portion (400C). Therefore, the second insertion grooves (410C) can be inserted deeply into each other so that the second connecting portions (400C) can be reliably connected. In addition, the second insertion grooves (410C) can have a shape in which the width gradually narrows along the direction extending from the end. Therefore, the second insertion grooves (410C) can be prevented from easily coming off when inserted into each other. Since a plurality of second insertion grooves (410C) are formed, the patient can adjust the connection position considering the size of his or her foot or discomfort. Alternatively, although the second insertion groove (410C) is shown in FIG. 10 as having a predetermined width, the second insertion groove (410C) may have a slit shape. That is, the second insertion groove (410C) may be formed in a line shape.

The second insertion projection (420C) is located between the second insertion grooves (410C) and can be formed with a wider width than the second insertion grooves (410C). When the second insertion groove (410C) formed in one second connecting portion (400C) is inserted into the second insertion groove (410C) formed in another second connecting portion (400C), the second insertion projections (420C) formed in each of the second connecting portions (400C) overlap each other to firmly support the connection between the second connecting portions (400C). For example, when two second insertion grooves (410C) are inserted into each other, one of the two second insertion protrusions (420C) formed in one second connecting portion (400C) is above one second insertion protrusion (420C) of the other second connecting portion (400C), and the other is below one second insertion protrusion (420C) of the other second connecting portion (400C). That is, when the two second connecting portions (400C) are connected to each other, each of the second insertion protrusions (420C) intersects with respect to the second connecting portion (400C). The connection method of the second insertion groove (410C) and the second insertion protrusion (420C) may be the same as the connection method of the first insertion groove (310C) and the first insertion protrusion (320C).

Through this method of connecting the second insertion groove (410C) and the second insertion projection (420C), the patient can easily connect the second connecting portions (400C) to each other. The second connecting portion (400C) is connected through the method of connecting the second insertion groove (410C) and the second insertion projection (420C) without including Velcro, so that the fastening force of the connecting portion may not decrease even if the heel protector (10C) is used repeatedly. In addition, the second connecting portion (400C) does not include a relatively complex connecting structure such as a buckle or belt, or a hard material such as a metal material, so that the patient's skin may not be compressed even if heel protector (10C) is worn for a long time. In addition, since the second connecting portion (400C) extends from the cover portion (200) that supports the patient's heel (H) and is fastened near the instep, a connecting member such as a belt or buckle is not inserted into the inside of the cover portion (200), thereby preventing the patient's skin from being compressed by the second connecting portion (400C).

The second connecting portion (400C) may include a fourth ventilation hole (430C).

As shown in Fig. 10, a plurality of fourth ventilation holes (430C) may be formed in the second connecting portion (400C). The fourth ventilation holes (430C) can prevent sweat or moisture, etc., from accumulating on the heel (H) of a patient wearing a heel protector (10C). The number, shape, and size of the fourth ventilation holes (430C) are not particularly limited. The fourth ventilation holes (430C) may be formed so as not to overlap with the second insertion groove (410C) in the width direction and length direction of the second connecting portion (400C). If the fourth ventilation holes (430C) are formed so as to overlap with the second insertion groove (410C), the cut-off area in the width direction and length direction of the second connecting portion (400C) increases, which may reduce the strength of the second connecting portion (400C). Therefore, the durability of the second connecting portion (400C) can be secured through such a configuration.

The second connecting portion (400C) may include a second fastening groove (440C).

A plurality of second fastening grooves (440C) are formed in the second connecting portion (400C) so that a fastening member can be inserted therein. For example, as shown in FIG. 10, a plurality of second fastening grooves (440C) may be formed longitudinally inward from a plurality of second insertion grooves (410C), second insertion protrusions (420C), and fourth ventilation holes (430C) formed in the second connecting portion (400C). For example, three second fastening grooves (440C) may be formed in one second connecting portion (400C). Alternatively, three or fewer or three or more second fastening grooves (440C) may be formed in one second connecting portion (400C). The shape of the second fastening groove (440C) and the insertion method of the fastening member are the same as those of the first fastening groove (220C), and a description thereof will be omitted.

The fastening member can connect the first fastening grooves (220C) to each other. The fastening member is made of a deformable elastic material, such as rubber. The fastening member can have a closed contour. A patient can insert the fastening member into one of the first fastening grooves (220C), and then spread both sides of the fastening member to seat it in the first fastening groove (220C). A subsequent patient can seat the fastening member in another first fastening groove (220C) in the same manner. Here, the other first fastening groove (220C) can be a first fastening groove (220C) that is positioned symmetrically with respect to the first fastening groove (220C) that was inserted first and the center of the cover portion (200C). Therefore, one fastening member can connect two first fastening grooves (220C) to each other. Accordingly, when the two first connecting parts (300C) are connected, the elastic member can pull both ends of the cover part (200C) so that the cover part (200C) can be closely attached to the patient's heel (H). In addition, the fastening member can closely attach the two first connecting parts (300C) toward the patient's instep so that the first connecting parts (300C) can maintain a tightly connected state.

The method by which the fastening member connects the second fastening grooves (440C) to each other may be the same as the method by which the first fastening grooves (220C) are connected, and a description thereof will be omitted. That is, when the two second connecting portions (400C) are connected to each other, the fastening member may press the two second connecting portions (400C) toward the patient's shin (S), thereby allowing the second connecting portions (400C) to maintain a close connection state.

The heel protector (10C) covers only the minimum body parts necessary for fixation, so that discomfort or pressure can be minimized even if the patient wears the heel protector (10C) for a long time. For example, when the patient wears the heel protector (10C), the first connecting part (300C) covers only a part of the patient's instep, and the second connecting part (400C) covers only a part of the patient's shin (S). Therefore, the patient's lower body may be exposed except for the heel (H) part, a part of the calf (C), a part of the instep, and a part of the shin (S) to prevent bedsores. Therefore, the heel protector (10C) not only has excellent ventilation, but also allows medical staff to easily observe the condition of the patient's lower body with the naked eye, and minimizes factors that may cause discomfort or pressure to the patient's body. In addition, the heel protector includes a first ventilation hole (110C), a second ventilation hole (210C), a third ventilation hole (330C), and a fourth ventilation hole (430C), thereby preventing moisture or sweat from accumulating even when the patient wears the heel protector (10C) for a long time. In addition, the heel protector includes a first fastening groove (220C), a second fastening groove (440C), a third fastening groove (340C), and a fastening member, thereby allowing the heel protector (10C) to adhere closely to the patient's body, and allowing the first connecting portion (300C) and the second connecting portion (400C) to be firmly connected.
