Description

An assistive device that compresses the superficial veins of the lumbosacral region

[0001] The present invention relates to an assistive device for compressing superficial veins in the lumbosacral region, and more specifically, to an assistive device for compressing superficial veins in the lumbosacral region that helps alleviate and treat lower back pain by blocking backflow of blood through compression of superficial veins in the lumbosacral region caused by venous insufficiency.

[0002] Venous insufficiency causes various symptoms when venous blood refluxes, preventing sufficient drainage of blood within tissues. This leads to increased pressure in the tissue capillaries, causing them to dilate and induce edema, as well as impairing the function of fine nerves. However, compressing the vein blocks the reflux and lowers the capillary pressure, thereby alleviating the symptoms caused by the reflux either immediately or shortly after compression.

[0003] In detail, as illustrated in Fig. 1, in the case of lower back pain caused by insufficiency of the superficial vein located beneath the skin of the lumbosacral region, such symptoms disappear when the entire skin of the lumbosacral region is gently compressed.

[0004] However, in the case of braces for treating lower back pain such as those in prior patent documents (documents 1 to 4), the lumbosacral region is in a lordotic state protruding forward even in a normal spine, and since the curvature is formed by the gluteal muscles of the lumbosacral region, a gap occurs between the brace and the skin, so the veins within the skin are not compressed, and thus symptoms caused by venous reflux do not improve even when the brace is worn. This is because if even one refluxing vein is not compressed, the venous reflux in that area remains, and thus the symptoms do not improve.

[0005] Specifically, since the paravertebral muscles on both sides of the spinous processes of the lumbar vertebrae protrude and the central area and the lateral side of the paravertebral muscles are sunken, there is a problem in that when wearing a standard brace, the central part of the lumbar spine cannot compress the skin, and the lateral end of the paravertebral muscles has weak skin compression.

[0006] In addition, since the lumbosacral region—the connection between the lumbar and sacral vertebrae—is in a lordotic state protruding forward in a normal spine, it is pointed out that wearing a standard brace causes this area to be the most elevated.

[0007] In addition, as disclosed in Patent Document 5, the waist support cushion disclosed in the lower back pain relief garment, which is in the form of pants that wraps around the abdomen and waist and fits into the thigh area, serves to stably support the curved part of the waist and is structured to include a pulling member connected to both sides and formed to correspond from both sides of the pelvis to the inner thigh, thereby improving symptoms of lordosis and relieving lower back pain. However, when wearing such a brace, only a part of the lumbosacral connection area is compressed, and problems persist in that the brace cannot compress the skin of the sacral area where the gluteus maximus protrudes on both sides of the sacrum because the brace lifts due to the gluteus maximus.

[0008] In addition, regarding the pants-shaped garment disclosed in Patent Document 6 that is expected to have a lower back pain exercise effect, it is a method of increasing abdominal pressure to reduce the burden on the lower back by changing muscle activity caused by the wearer's walking movement and correcting posture, thereby preventing, improving, and alleviating lower back pain. Since the sacral region is due to the gluteus maximus on both sides, the lumbar region is due to the paravertebral muscles, and the lumbosacral region is in a lordotic state, a separation occurs from the skin, so the superficial veins are not compressed, and the pressure sensation from wearing is increased, making it unsuitable for application to subjects who have difficulty walking or standing due to lower back pain.

[0009] In addition, Patent Document 7 is a structure that wraps around the lumbar and thoracic regions and does not compress the sacral region and the lumbosacral connection region. Even if the present invention is applied to the sacral region, the central part of the pad protrudes sharply, and due to the characteristics of the lumbosacral connection region which is sunken in a soft curved shape, it only compresses about 10% of the center and cannot compress most of it. Therefore, it is a structure that is not suitable for use in the treatment of venous insufficiency, as it requires compressing the entire skin of the lumbosacral region.

[0010] In addition, Patent Document 8 is a composite spinal protector that supports the thoracolumbosacral region. Although it supports the lumbar and sacral regions, the reinforcing plate that contacts the lower back is in a curved shape that protrudes backward, so it first contacts the posterior superior iliac spine and gluteus maximus of the sacral region, and thus has a structure that cannot compress the skin in the center of the lumbosacral connection.

[0011] In addition, Patent Document 9 is a belt-type brace designed to protect the waist by easily reinforcing lumbar compression force by connecting auxiliary compression members in a pulley manner, as shown in Fig. 2. However, when the member is pulled strongly, the belt becomes taut, and in cases where the gluteus maximus is well developed or the anterior-posterior superior iliac spine is large, the belt separates from the lumbosacral connection and the skin of the sacral region, making it difficult to expect a venous compression effect.

[0012] The present invention has been devised to resolve the aforementioned conventional problems, and,

[0013] The purpose is to provide a compression brace for superficial venous venous compresses of the lumbosacral region that is effective in relieving and treating lower back pain caused by superficial venous insufficiency in the lumbosacral region by gently compressing the entire skin in individuals with normal lumbar curvature and well-developed paravertebral and gluteus maximus muscles, while being convenient to use by attaching it to pants, corsets, or waist belts, maximizing a snug fit in the lumbosacral region, and offering good cost-effectiveness.

[0014] To achieve the above objective, the present invention relates to an assistive device for compressing superficial veins in the lumbosacral region, characterized in that the entire body has a structure that evenly and gently adheres to and compresses the skin of the superficial vein area according to the shape of the lumbosacral skeletal region, wherein the lumbosacral portion, the lumbosacral connecting portion, and the sacral portion are formed as a single unit.

[0015] In addition, the present invention relates to an assistive device for compressing superficial veins in the lumbosacral region, characterized by a single-body structure that evenly and gently adheres to and compresses the skin of the superficial vein area according to the shape of the lumbosacral skeletal region, wherein the single-body structure is formed such that it compresses only the skin of the lumbosacral connection region without considering the lumbar or sacral regions, and has a circular pad with a diameter of 130 mm, with a central thickness of 25 mm and a rim thickness of 5 mm, and the thickness gradually decreases in a gentle curved shape from the center to the rim.

[0016] In addition, the present invention relates to an assistive device for compressing superficial veins of the lumbosacral region, characterized in that the overall body of the present invention has a flat surface with dimensions of 200 mm in width and 200 mm in length, wherein the lumbar portion of the body is formed such that it is formed to closely correspond and compress the 3rd and 4th lumbar vertebrae, with the central part of the pad being the thickest, the part in contact with the paravertebral muscle being the thinnest, and the part lateral to the paravertebral muscle being thicker than the part in contact with the paravertebral muscle, and the lumbar portion is provided with a central lumbar vertebral ridge with a thickness of 15 to 15.3 mm, and a butterfly-shaped paravertebral muscle-contacting indentation is formed on the left and right sides of the protrusion with an indentation depth of 5 mm and a thickness of 7.3 to 10 mm at the outer edge of 33 mm.

[0017] In addition, the lumbosacral connecting portion of the overall body of the present invention is formed with a smooth curve so as to closely correspond to and compress the 4th and 5th lumbar vertebrae, with the central portion being the thickest and the outer portion being thinner, forming a slope shape, wherein the thickness of the central portion is 25 mm and the outer portion is formed with a slope shape with a thickness of 5 mm, and the longitudinal line connecting the lumbosacral connecting portion and the lumbar portion is formed with a slope thickness of 10.2 mm from 25 mm, and the invention relates to an assistive device for compressing the superficial veins of the lumbosacral portion.

[0018] In addition, the present invention relates to an assistive device for compressing superficial veins in the lumbosacral region, characterized in that the sacral portion of the overall body of the present invention is formed with a lower end having a width of 75 mm and a thickness of 10.2 mm so as to closely correspond to a protruding part like a triangular skeleton formed by the gluteus maximus and the sacrum, and the connecting portion with the lumbosacral portion is formed with a width of 165 mm and a thickness of 17.5 mm and is formed as a rhombus-shaped slope overall.

[0019] In addition, the present invention relates to an assistive device for compressing superficial veins in the lumbosacral region, characterized in that the overall body and the single body of the present invention are formed of a memory foam material with a hardness of 1 to 5 so as to evenly and gently adhere and compress the skin of the superficial vein area according to the shape of the lumbosacral skeletal region.

[0020] In addition, the present invention relates to an assistive device for compressing superficial veins in the lumbosacral region, characterized in that the overall body and the single body of the present invention have a hollow portion formed inside, and an injection port communicating with the hollow portion is formed on one side of the body, and the injection port is connected to an external injection device to inject air, water, a phase change material, etc. supplied by the injection device into the hollow portion to expand the body, thereby evenly and gently compressing the skin of the superficial vein area according to the musculoskeletal shape of the lumbosacral region.

[0021] In addition, the present invention relates to an assistive device for compressing the superficial veins of the lumbosacral region, characterized in that the entire body and the single body of the present invention further include a pressure sensor for measuring expansion pressure when the body is in close contact with and compresses the skin of the superficial vein (SV) area according to the shape of the lumbosacral skeletal region, and the pressure sensor is installed on the outer surface or within the hollow portion of the body.

[0022] In addition, the present invention relates to an assistive device for compressing superficial veins of the lumbosacral region, characterized in that the full body and the standalone body of the present invention are used by selectively fitting or attaching them to any one of pants, a corset, pantyhose, a waist-pelvic belt, or a conventional lumbar brace.

[0048] The best mode for carrying out the present invention is to use an orthotic device having a structure that evenly and gently compresses the superficial veins distributed within the skin of the lumbosacral region by utilizing a whole body or a lumbosacral connection-only body formed to correspond to the anatomical structure of the lumbosacral region. Specifically, the orthotic device according to the best mode of the present invention is a whole body in which the lumbar region, the lumbosacral connection, and the sacral region are integrally formed. It is formed to have different thicknesses and curvatures for each part, taking into account the musculoskeletal shape of the human lumbosacral region, such as the paravertebral muscle protrusion of the lumbar region, the depression caused by lordosis of the lumbosacral region, and the gluteus maximus protrusion of the sacral region. This ensures that the skin of the superficial vein area throughout the lumbosacral region is uniformly compressed without localized overpressure. The whole body is preferably formed of a memory foam material with a hardness range of 1 to 5, and may be configured to form a hollow space inside and inject air, water, or a phase change material to adjust the inflation pressure according to the user's body shape and wearing environment. In addition, the main body further includes a pressure sensor to measure skin contact pressure and adjust the injection amount based on this, thereby preventing excessive pressure while stably maintaining the therapeutic effect. The orthosis according to the best mode of the present invention is preferably used by inserting or attaching it to existing wearable orthoses or clothing, such as waist-pelvic bands, lumbar braces, pants, corsets, or pantyhose, and thereby effectively blocking reflux of superficial veins in the lumbosacral region, thereby immediately alleviating or continuously improving venous low back pain.

[0049] The present invention having such characteristics may be explained more clearly through preferred embodiments thereof.

[0053] As illustrated in FIGS. 3 to 22, the orthotic device for compressing the superficial veins of the lumbosacral region according to the present invention is formed with an overall body (100) having a structure that evenly and gently adheres to and compresses the skin of the superficial vein (SV) region according to the shape of the lumbosacral skeletal region for treating or alleviating lower back pain caused by insufficiency of the superficial vein (SV) region distributed in the lumbar region corresponding to the 3rd and 4th lumbar vertebrae (L3, L4); the lumbosacral region corresponding to the 5th lumbar vertebra and 1st sacral vertebra; and the sacral region corresponding to the remaining part of the sacrum (2nd to 5th sacral vertebrae). The overall body (100) is formed such that the lumbar region (10), the lumbosacral connecting region (20), and the sacral region (30) are formed as a single unit.

[0054] In the lumbar region (10) of the 3rd and 4th lumbar vertebrae (L3, L4) above, the paravertebral muscles on both sides of the spinous process of the lumbar vertebrae protrude, and the central region and the outer side of the paravertebral muscles are sunken. Therefore, when wearing a general brace, the central region of the lumbar vertebrae cannot compress the skin, and the outer end of the paravertebral muscles has weak skin compression force. Accordingly, the lumbar region of the overall body (100) according to the present invention must have the thickest central region, the thinnest region in contact with the paravertebral muscles, and the outer side of the paravertebral muscles is formed to be thicker than the paravertebral muscle contact region. In the case of the 5th lumbar vertebra (L5) and 1st sacral vertebra (S1) above, the lumbosacral connection part (20) is in a lordotic state where it protrudes forward in the case of a general spine, so when viewed from behind, it is sunken, and when wearing a general brace, this region is the highest. Since this area has no muscle and is almost flat with a triangular portion of the multifidus tendon, but has a slightly indented central part, the lumbosacral connection part (20) according to the present invention is formed in a slope shape with the thickest and flattest part and a smooth curve, with the central part being the thickest and the outer part being thinner than that, and the sacral part (30) corresponding to the remaining part of the sacrum (sacrum 2 to 5) has the gluteus maximus (GM) protruding on both sides of the sacrum as shown in FIG. 22-a, so when a general brace is worn, the brace lifts due to the gluteus maximus and cannot compress the skin of the sacral part.

[0055] Therefore, it is desirable to form the compression device in this area to protrude and closely correspond to the triangular depression formed by the gluteus maximus (GM) and the sacrum.

[0056]

[0057] The rectangular overall body (100) according to the present invention formed as described above is described in detail through the attached drawings as follows.

[0058] As shown in FIGS. 4 to 8 and FIGS. 12, 13b, 14b, 15b, 16b, 17b, and 18b, the overall body (100) according to the present invention has a planar dimension of 200 mm in width and 200 mm in height, and corresponds to the central part and the outer part of the paravertebral muscles protruding on both sides of the spinous process of the lumbar vertebra and the area where the paravertebral muscles are sunken. As shown in the cross-sectional view along lines C-C', D-D', and E-E' of FIG. 6 and FIGS. 8c, 8d, and 8e, the central lumbar ridge (10a) is provided with a thickness of 15 to 15.3 mm, and on the left and right sides of the protrusion, the indentation bottom thickness is 5 mm, and at the outer rim 33 mm portion, the thickness is 73 to 10.2 mm, with a planar butterfly shape. The paravertebral muscle close indentation (10b) is formed in a left and right arrangement.

[0059] Here, the lumbosacral connecting portion (20) connected to the lumbar portion (10) is in a lordotic state where it protrudes forward in most spines, and is composed of a flat multifidus tendon without muscles and has a slightly indented central portion. Accordingly, it is connected to the sacral portion (30) with a width of 200 mm as shown in the cross-sectional view along line B-B' of FIG. 6 and FIG. 8b, and has a smooth curve with the thickest central portion being 25 mm, and the outermost portion being 5 mm thick in a slope shape, and the longitudinal line connecting the lumbosacral connecting portion and the lumbar portion is formed as a slope with a height of 10.2 mm from 25 mm as shown in FIG. 8d.

[0060] In addition, the sacral portion (30) connected to the above lumbosacral connecting portion (20) is made such that it closely corresponds to the triangular depression formed by the gluteus maximus (GM) protruding on both sides of the sacrum and the sacral portion, with the upper portion having a width of 75 mm and a height of 10.2 mm as shown in FIG. 6 and FIG. 7a and b, and the connecting portion with the lumbosacral connecting portion (20) is formed as an inverted ladder-shaped slope with dimensions of 165 mm in width and 17.5 mm in height as shown in the cross-sectional view along line AA' of FIG. 6 and FIG. 8a.

[0061] As described above, in addition to the overall body (100) of the assistive device for compressing the superficial veins of the lumbosacral region according to the present invention, there is no need to consider the musculoskeletal system of the lumbosacral region when venous insufficiency is present only in the lumbosacral region and not in the lumbar or sacral region, so the musculoskeletal system of the lumbosacral region is considered and only the musculoskeletal system of the lumbosacral region is considered and only the area is compressed. As illustrated in FIG. 10, FIG. 13a, and FIG. 14a, the single-type body (200) is formed such that it compresses only the skin of the lumbosacral region without considering the lumbar or sacral region, and the pad has a diameter of 130 mm, with a central thickness of 25 mm and a rim thickness of 5 mm, and the thickness gradually decreases in a gentle curved shape from the center to the rim, as shown in FIG. 10.

[0062]

[0063] The overall body (100) of the assistive device for compressing the superficial veins of the lumbosacral region according to an exemplary embodiment of the invention described above is formed with a shape corresponding to the lumbosacral musculoskeletal structure to evenly and gently compress the skin of the lumbosacral region, and is made of memory foam material with a hardness of 1 to 5 and an injectable expansion member to treat or alleviate lower back pain caused by insufficiency of the superficial veins (SV) distributed in the lumbosacral region, the lumbosacral connection region, and the sacral region. At this time, the single body (200) is also formed of memory foam material with a hardness of 1 to 5 and an injectable expansion member.

[0064]

[0065] As shown in FIGS. 10 to 13, the overall body (100) and the single body (200) of the assistive device for compressing the superficial vein of the lumbosacral region according to another preferred embodiment of the present invention described above have a hollow portion (110) formed inside and an injection port (120) communicating with the hollow portion (110) formed on one side.

[0066] Here, the injection port (120) is connected to an external injection device (not shown), and any one of air, water, or phase change material supplied by the injection device is injected into the hollow portion (110) to expand the main body, thereby evenly and gently compressing the skin of the lumbosacral region. At this time, the injection port (120) and the injection device are connected through an injection tube (130).

[0067] In addition, a pressure sensor (140) for measuring expansion pressure when the skin of the lumbosacral region is closely compressed is installed in the main body (100, 200) as shown in FIG. 13, and the pressure sensor (140) is installed on the surface of the main body (100) that contacts the user's skin. At this time, the control unit controls the amount of air, water, phase change material, etc. injected according to the value measured by the pressure sensor (140) and the value set in the control unit (not shown) provided externally.

[0068]

[0069] As described above, the overall body (100) and the lumbosacral connection part single body (200) of the lumbosacral compressing assistive device according to the present invention are used by selectively attaching or fitting them to any one of the following: a waist-pelvic band, a lumbar brace, pants, a corset, or pantyhose for treating lower back pain, as shown in FIGS. 14 to 22. The device is a compressive device for the superficial veins of the lumbosacral region that evenly and gently compresses the superficial veins within the skin of the lumbosacral region to treat or alleviate lower back pain caused by reflux of the superficial veins of the lumbosacral region, thereby causing the lower back pain to be immediately relieved or disappear. It is a useful invention that is cost-effective and easy to use, as it has a high degree of adhesion to the lumbosacral region and can be easily worn by subjects who have difficulty walking or standing due to lower back pain, and can be inserted into an assistive device already in possession.

[0071] Although the invention has been described with reference to the embodiments above, those skilled in the art will understand that various modifications and changes can be made to the invention without departing from the spirit and scope of the invention as set forth in the following claims. Furthermore, the embodiments disclosed in the present invention are not intended to limit the technical spirit of the invention, and all technical spirits within the scope of the following claims and equivalents should be interpreted as being included within the scope of the rights of the present invention.

[0072] The present invention relates to an orthotic device intended for the alleviation and treatment of lower back pain caused by superficial venous insufficiency in the lumbosacral region. It provides a function to block venous reflux by selectively compressing superficial veins using a compression body shaped to correspond to the anatomical and musculoskeletal structure of the human lumbosacral region. The superficial venous compression orthotic device for the lumbosacral region according to the present invention can be mass-produced using known industrial materials such as memory foam and inflatable materials, and can be manufactured stably through molding, processing, and assembly processes. Furthermore, it can be implemented in various forms, such as a full body and a body with a lumbosacral connection section, allowing for selective application depending on the purpose of use and the patient's condition. In addition, since the present invention can be inserted into or attached to various wearable medical orthotics or clothing, such as existing waist-pelvic bands, lumbar orthotics, pants, corsets, and pantyhose, it is applicable to various industrial fields, including the medical device industry, the rehabilitation orthotic industry, and the functional clothing industry. In particular, since this is an orthotic based on a novel pathophysiological mechanism of low back pain caused by venous insufficiency, it has independent industrial utility value that distinguishes it from existing musculoskeletal-centered low back pain orthotics. Therefore, the present invention can be repeatedly and commercially produced and used in the medical device manufacturing industry, the rehabilitation and pain relief orthotic industry, and the functional wearable healthcare industry, and thus its industrial applicability is fully recognized.
