Description

Pressure belt and apparel comprising same

Technical Field

The invention relates to a pressure belt and apparel comprising the pressure belt.

Background

For the prevention and treatment of circulatory disorders such as lymphedema and varicose veins, it is known to apply compression clothing or bandages. By compressing the clothes or the bandage, certain pressure is applied to the affected part with circulatory diseases, so as to eliminate swelling and ache caused by circulatory disorder of the affected part, prevent varicose vein and deep vein thrombosis, or promote recovery and healing after treatment operation.

Compression garments are typically made of synthetic elastic fibers that can be worn against the surface of the user's torso and/or limbs and exert uniform pressure. However, in certain specific situations, such as requiring additional pressure to be applied to selected areas (also known as eccentric compression), existing compression garments are not satisfactory.

Other ways of applying pressure are known, such as bandages, which have the advantage of a high degree of flexibility, and the user can wrap the bandage around the desired area to apply pressure as required. However, this approach still does not allow for the application of additional pressure to localized areas while applying some pressure to the user as a whole. Furthermore, wrapping bandages is time consuming and pressure application relies on the experience of the user, failing to ensure a reliable level of compression.

In view of the foregoing, there is a need for a pressure belt and apparel incorporating the pressure belt that reliably and continuously achieves eccentric compression.

Lymphedema and varicose veins are two common types of circulatory disorders. The lymphatic system is part of the circulatory system and includes a network of lymphatic conduits that connect lymphatic nodes together and function to return interstitial fluid to the blood. Lymph nodes are tissues of the immune system and are the primary sites for immune cells to control infections and toxins. Like veins, lymphatic vessels have one-way valves to prevent reflux. Lymph fluid passes through the lymphatic vessels unidirectionally by contraction of muscles and physical movements, as well as external compression of the lymphatic vessels by external forces.

Cancer cells can spread from the origin of the tumor to other parts of the body through the lymphatic system. Thus in the treatment of cancer, for example in the treatment of breast cancer, weak radioactive and/or coloured dyes are used to identify the "sentinel" lymph nodes to which lymph fluid first flows in the cancerous tissue region and to resect these lymph nodes. If cancer cells in the sentinel lymph nodes are found to have shown that the cancer is invading outward, and/or that its extent or nature of spread is confirmed, additional lymph nodes of the upstream group need to be resected in a subsequent procedure.

The excision of lymph nodes can substantially impair the ability of the lymphatic system to drain lymph fluid from the affected site, which results in stagnation and retention of lymph fluid and causes swelling (lymphedema), as well as associated inflammation of the tissue. Swelling and inflammation from lymphoedema is very painful and can lead to deformities in the tissues and extremities, which can cause pain and disable the patient. Lymphedema tissue also increases the risk of infection. In more severe cases, the affected tissue may develop fibrous sclerosis.

Varicose veins are a series of lesions of superficial varicose veins, pressure elevation and skin microcirculation disturbance caused by blood backflow and backflow obstruction due to venous valve insufficiency, obstruction, muscle pump insufficiency and the like.

Venous Thromboembolism (VTE) includes Pulmonary Embolism (PE) and Deep Vein Thrombosis (DVT). Deep Vein Thrombosis (DVT) causes severe cardiovascular disease in patients, which has resulted in a significant increase in the incidence of pulmonary thromboembolism over the last 20 years, and even death in patients with acute deep vein thrombosis, which has been caused by a number of risk factors including various wounds, aging, eating habits, obesity, genetic factors, and cancer. DVT patients have a higher risk of mortality. When patients age 40 years or older, trauma or surgery, malignancy (at least 6 times increased risk of developing VTE), long-term bedridden or braked, chemoradiotherapy, surgical general anesthesia and other dangerous factors, the probability of occurrence of VTE is extremely easy to increase. Clinical studies have shown that inferior vena cava valve thromboembolism is a major factor in proximal deep vein thrombosis. The method of preventing VTE includes physical precautions and pharmaceutical precautions. Physical methods include antithrombotic gradient pressure socks and the like. The medicine method comprises the treatment of subcutaneous injection of low molecular heparin and the like. Compared with the medicine method, the physical preventive measures are safer, more timely and have no adverse reaction. The antithrombotic gradient pressure socks are common measures for preventing VTE, and many research results show that the gradient pressure socks have remarkable effect in preventing venous thromboembolism, and can remarkably reduce the occurrence rate of VTE.

For circulatory disorders such as lymphedema and varicose veins, it is known to apply compression clothing or bandages. By compressing the clothes or the bandage, certain pressure is applied to the affected part with circulatory diseases, so as to eliminate swelling and ache caused by circulatory disorder of the affected part, prevent varicose vein and deep vein thrombosis, or promote recovery and healing after treatment operation. Compression garments are typically made of synthetic elastic fibers that can be worn against the surface of the user's torso and/or limbs and exert uniform pressure.

However, in certain specific situations, such as requiring additional pressure to be applied to selected areas (also known as eccentric compression), existing compression garments are not satisfactory.

In addition, other means of applying pressure, such as bandages, still fail to achieve the application of additional pressure to localized areas while applying some pressure to the user as a whole. Furthermore, wrapping bandages is time consuming and pressure application relies on the experience of the user, failing to ensure a reliable level of compression.

Aiming at the defects of the prior art, the present disclosure provides a novel pressure belt capable of reliably and continuously realizing eccentric pressurization and a piece of clothing comprising the pressure belt. Exemplary embodiments of the pressure belt and apparel including the pressure belt set forth in the present disclosure will be exemplarily described below with reference to the accompanying drawings.

As shown in fig. 1 and 2, at least one embodiment of the present disclosure proposes a pressure belt including a main body 1 and a protrusion 2 attached to the main body 1, the protrusion 2 being configured to eccentrically pressurize a user.

It is noted that the "eccentric compression" or "eccentric compression" described in this disclosure is particularly beneficial for lymphedema and post-varicose vein treatment. Such as vascular sclerotherapy, laser ablation, or radio frequency ablation, additional pressure is applied to the trend of the vein being treated (e.g., the great saphenous vein or the small saphenous vein) to help isolate the vein being treated from the normal vein, so as to allow for fibrosis recovery within days after treatment. In particular, eccentric compression refers to the application of additional pressure in a given area in addition to the application of uniform pressure to the user's limb. In fig. 13, a pressure distribution diagram of the pressure belt in the same section of the lower limb is shown with the pressure mode of the prior art (e.g. pressure socks). The solid line shows the pressure profile of the pressure belt of the present disclosure, which is particularly advantageous for post-venous recovery, because the eccentric compression concept of the pressure belt of the present disclosure is able to give more pressure to the vein being treated than the prior art uniform compression. For another example, for lymphedema, eccentric compression may be applied to sites where there is a high risk of edema (lymphatic vessels), and greater pressure may be applied to these sites to aid in detumescence and recovery of these sites. A typical example is lymphedema. However, the present disclosure is not limited to the use of a particular pressure band, and thus may be used in one or more ways to treat oedema caused by tissue or joint, surgery, tissue or joint inflammation, and other physiological conditions.

For convenience of description, the following exemplary embodiments of the present disclosure will be described by taking a pressure belt for lower limb wearing as an example, the present disclosure is not limited thereto, and the pressure belt for lower limb may be modified for other trunk or limbs, such as lower abdomen, chest, thigh, lower leg, thigh, forearm, inguinal region, etc.

As shown in fig. 1, the pressure belt includes a main body 1 and a protrusion 2. The main body 1 defines a width direction W and a length direction L perpendicular to each other. The body 1 comprises a first surface 3, a second surface 4 and a strap 5. The body 1 as a whole is flexible and the first surface 3 is intended to be in contact with a user and may comprise a skin-friendly material, such as an elastic fabric (knitted warp or weft knitted elastic fabric) or a PU (polyurethane) sponge. The second surface 4 is opposite to the first surface 3, and the second surface 4 may comprise a raised cloth cover for attachment of the strap 5. In an alternative embodiment, the first surface 3 may also be used for attachment of the strap 5.

The strap 5 extends from at least one side of the main body 1 in the width direction W. Illustratively, the strap 5 comprises a plurality of sub-straps arranged at intervals in the length direction, at least a portion of which at the end remote from the main body may be provided with an attachment portion 9 for attachment to the second surface 4. In the present embodiment, the attachment portions 9 are provided on the first surfaces 3 of the plurality of sub-bands. For example, the attachment portion 9 may have (i.e., hook and loop fastener) ends, respectively, the second surface 4 comprises the corresponding +.>(i.e., hook and loop fasteners) surfaces, such as raised surfaces. The attachment 9 and the second surface 4 are connected by hook and loop fasteners. At least a portion of the sub-band of the band 5 is wrapped around the torso or limb of the user, e.g. overA limb or lower limb and is attached to the second surface 4, thereby securing the pressure band to the torso or limb of the user. The strap 5 may be elastic so as to be able to stretch and apply pressure to the user when wrapped around and secured to the user's torso or limbs. Alternatively, the width of the strap 5 in the length direction L may be in the range of 30 to 60mm, for example 30 to 40mm, 40 to 50mm, 50 to 60mm or 30mm, 35mm, 40mm, 45mm, 50mm or 60mm.

The protrusions 2 are attached to the first surface 3, for example in a fixed, detachable or adjustable manner to the first surface 3. It should be noted that the "protrusion" referred to in the present disclosure is not limited to a stripe-shaped protrusion, a dot-shaped protrusion, or a block-shaped protrusion. For example, the strip-shaped projections have a length and a width, and the length is much greater than the width, e.g., the length exceeds the width by more than 5 times. The following partial embodiments provide the projections in a strip shape, the concept of which is that the vein and vein trend of the human body is also generally strip-shaped, the strip-shaped projections being intended to conform to the trend of the vein of the lower limb to apply additional pressure to a particular vein of the lower limb. In other cases, spot-like projections or block-like projections are possible even plate-like projections, for example, where the pressure-exerting area is such as the chest, abdomen, or where the limb requires these projections.

For describing the protrusion of the present disclosure, the defining protrusion 2 has a first length d extending in the length direction L, a first height h perpendicular to the first surface 3, and a first width k in the width direction W.

The first length d may be set to be less than or equal to the length of the body 1. For example, the first length d may be equal to the length of the body 1, i.e. the protrusion 2 extends along the entire length of the pressure belt, such as the embodiments shown in fig. 5 to 8 or fig. 19. Alternatively, the first length d may be smaller than the length of the body 1, such as the embodiment shown in fig. 1 and 2.

In the embodiment shown in fig. 1 and 2, at least a portion of the projection 2 is straight along the length direction L. Alternatively, the protrusions 2 may be arcs or a combination of straight and curved lines. Preferably, the projections 2 may be arranged to follow the vein or lymphatic vessel trend.

Alternatively, the first height h of the protrusions 2 may be in the range of 2mm to 10mm. For example, 2mm to 4mm, 4mm to 6mm, 6mm to 8mm, 8mm to 10mm or 2mm, 4mm, 5mm, 6mm, 8mm or 10mm. The magnitude of the first height h should be selected according to the magnitude of the eccentric pressing required. It will be readily appreciated that the greater the first height h, the greater the eccentric compression pressure at the same strap attachment location (i.e., the same pressure applied uniformly). It should be noted that a suitable amount of eccentric compression should be employed. For example, if the pressure of the eccentric compression is too great, not only discomfort is caused to the user, but also the deep veins of the lower limb are even pressed, resulting in obstruction of venous return of the lower limb. Conversely, if the pressure of the eccentric pressing is too small, it is obvious that the eccentric pressing effect to be achieved by the present invention cannot be achieved.

Alternatively, the first width k of the protrusion 2 may be in the range of 5mm to 60mm, for example, 5mm to 20mm, 20mm to 30mm, 30mm to 40mm, 40mm to 60mm or 5mm, 8mm, 15mm, 20mm, 30mm, 40mm or 60mm. The first width k of the protrusion 2 may be selected according to the width of the vein to be eccentrically pressurized, and different widths may be selected according to different veins, which is not limited in this disclosure.

Alternatively, the shape of the protrusion 2 in a cross section perpendicular to the first surface 3 may be at least one of a semicircle, a triangle, a rectangle, a trapezoid, or a combination thereof. For example, in the embodiment shown in fig. 14, the cross-sectional shape of the protrusion 2 is trapezoidal. Preferably, the cross-sectional shape of the protrusion 2 is set to be larger near the first surface 3 than far from the first surface 3 in order to secure a reliable connection and rigidity with the first surface 3.

Alternatively, the material of the protrusions 2 may comprise at least one of a linear combed pile, brushed cotton or polymeric material, a woven fabric, a pillow or core material, a fabric filler, a gel, a silicone, a rubber or an air bag, or a combination of the above materials, for example.

Referring again to fig. 1 and 2, the body 1 may further include first and second portions 6 and 7 distributed along the length direction L, and a connection portion 8 between and connecting the first and second portions 6 and 7. Specifically, the dimension of the connecting portion 8 in the width direction W is smaller than the dimensions of the first portion 1 and the second portion 2 in the width direction W. The first portion 6 may correspond to a lower limb thigh portion, the second portion 7 may correspond to a lower limb shank portion, and the connection 8 corresponds to a lower limb knee joint portion. Compared with the pressure sock which entirely surrounds the lower limb, the connecting part 8 is arranged to stagger the knee joint part, so that the flexibility of the lower limb when a user wears the pressure belt can be improved, and the joint part is prevented from interfering when moving.

Illustratively, the strap 5 may extend in the width direction W on the first and second portions 6, 7, respectively. In other words, in the embodiment shown in fig. 1 and 2, the connection 8 does not comprise a strap 5. Specifically, the strap 5 extends in the width direction W from both sides of the main body 1, and the strap 5 includes a plurality of first sub-straps 51 and a plurality of second sub-straps 52 that are arranged at intervals in the length direction L.

A plurality of first sub-bands 51 are provided on a first side of the main body 1, for example, the left side in fig. 1. A plurality of second sub-bands 52 are provided on a second side of the main body 2 opposite the first side, such as the right side in fig. 2. In the length direction L, a first opening 10 is defined between two adjacent first sub-bands 51 for receiving a second sub-band 52 on the opposite side. Accordingly. A second opening 11 is defined between two adjacent second sub-bands 52 for receiving the opposite side first sub-band 51. In other words, in the length direction L, the first sub-bands 51 and the second sub-bands 52 are alternately arranged. With the above arrangement, the plurality of first sub-bands 51 and the plurality of second sub-bands 52 form an arrangement resembling an array of fingers, the first sub-bands 51 are wrapped around the lower limb and received in the second openings 11 on the opposite sides, and the second sub-bands 52 are wrapped around the lower limb and received in the first openings 10 on the opposite sides, helping to form a reliable connection, and this arrangement can effectively reduce the gaps between the adjacent bands 5 so as to ensure the durability and uniform distribution of the applied pressure. In addition, by means of a plurality of sub-bands, the pressure application may be divided into different parts, facilitating the application of different pressures at different locations of the lower limb, such as gradient pressure, as will be described in more detail below.

In the embodiment shown in fig. 1, the bulge 2 is arranged on the right side of the first surface 3 for facilitating eccentric compression of the great saphenous vein of the lower limb. Accordingly, the bulge 2 extends along the venous run of the great saphenous vein of the lower limb. The protrusions 2 may be fixedly attached to the first surface 3 of the body 1, e.g. glued, welded or sewn to the first surface 3 of the body 1.

In the present embodiment, the protrusion 2 extends along the entire length of the first and second portions 6 and 7, and is broken only at the connection portion 8, forming the first and second sub-protrusions 21 and 22. This arrangement allows for a major degree of flexibility of the lower limb at the connection 8. Further, as shown in fig. 1 and 2, the first portion 6, the second portion 7 and the connecting portion 8 are formed as one body, and the main body 1 is formed of left and right halves, the first portion 6, the second portion 7 and the connecting portion 8 in each half being formed as one body, the left and right halves being connected together by a sewing process, the sewing connection line 12 being particularly shown in fig. 1.

Further, as shown in fig. 1 to 8, in the planar expanded state of the pressure belt, the pressure belt widths of the first portion 6 to the second portion 7 substantially sequentially decrease in the length direction L, which conforms to the variation law of the circumference of the lower limb of the human body from thigh to shank.

It is known that in the prevention, treatment and postoperative recovery of varicose veins of the lower limb, it is advantageous to apply a gradient pressure to the lower limb which increases in sequence from the ankle to the thigh, helping to promote venous return and alleviating the symptoms of varicose veins. Therefore, in combination with the above formula, the pressure belt width of the first portion 6 to the second portion 7 in the length direction L can be sequentially reduced, and the width of the strap 5 in the length direction L can be sequentially reduced, with the same tension in the pressure belt. While the tension in the pressure belt is generally related to the elongation of the body 1. The pressure belt provided by the present disclosure adopts the above-mentioned size design, so that the user can simply and rapidly realize the gradient pressure on the lower limb under the condition that the user applies approximately the same stretching degree on each sub-bandage, and the pressure of the pressure belt is not required to be indicated by an additional pressure indicating device.

Optionally, the second surface 4 of the pressure band may also be provided with graduation marks (not shown), for example indicating the measured circumference of the lower limb at that portion, on which the first or second sub-band 51, 52 may be wound and fixed. Whereas the position of the graduation marks is substantially related to the recommended pressure of the lower limb at that portion. Alternatively, the scale markings may represent only a scale from 1 to n to indicate the pressure level of the lower limb at that portion, and the user may look up the actual pressure against the pressure level corresponding to the different circumference in cooperation with the "circumference-pressure level gauge" attached to the pressure band.

Fig. 3 and 4 show schematic diagrams of a pressure belt according to another embodiment of the present disclosure. In the present embodiment, the projections 2 are arranged in an arc shape and extend in particular along the venous run of the great saphenous vein of the lower limb.

Fig. 5 and 6 show schematic diagrams of a pressure belt according to yet another embodiment of the present disclosure. For brevity, the following description is only directed to the differences between the embodiments and the foregoing embodiments, and the structures not involved are the same as or similar to the foregoing embodiments, and are not repeated herein.

In this embodiment, the protrusions 2 extend along the entire length of the first and second portions 6, 7, which has the advantage that the protrusions 2 can be replaced or adjusted in their entirety and that machining and assembly are easier. In order to apply pressure through the protrusions 2 also at the positions of the connection parts 8, the connection parts 8 may be provided with connection part straps 53 extending in the width direction W from one side of the body 1, and the connection part straps 53 may be integrally formed with the connection parts 8 or connected to the connection parts 8 through a sewing process, so that fixation and pressure may be applied through the connection part straps 53 also at the knee joint part when worn. The protrusion 2 and the connection band 53 may be connected or separated. For example, a portion of the boss 2 located at the connection portion 8 is connected with the connection portion strap 53, or the boss 2 and the connection portion strap 53 may be separated without a connection relationship, which may be adjusted or modified according to wearing comfort of the patient.

Fig. 7 and 8 show schematic diagrams of a pressure belt according to yet another embodiment of the present disclosure. In this embodiment, the first portion 6 and the strap 5 and the connection 8 within it are formed as one piece, i.e. without stitching or connecting lines. While the portions of the second portion 7 near the lower end are split from the middle and then spliced together, thus helping to follow the contour of the lower leg.

Fig. 10 and 11 show schematic diagrams of pressure bands according to alternative embodiments of the present disclosure. Alternatively, the first portion 6 and the second portion 7 may also be separate portions, separate from each other. That is, the first and second portions 6, 7 may not be connected together by the connection 8, but the first and second portions 6, 7 may be secured to different locations of the torso or limbs, respectively. For example, the first portion 6 may be fixed to the thigh portion and the second portion 7 may be fixed to the calf portion.

Figures 9 and 12 show schematic views of the pressure band of the different embodiments worn by the lower limb of the user, respectively. The bulge 2 applies an eccentric pressure just against the great saphenous vein trend. As can be seen from fig. 9 and 12, the pressure belt proposed by the present disclosure fixes the pressure belt to the lower limb of the user by the strap 5, can be well fitted to the lower limb of the user and applies pressure to the lower limb, and in particular, can also realize eccentric pressurization by the boss 2. In the embodiment shown in fig. 9 and 12, the first portion 6 and the second portion 7 respectively pressurize the thigh and the calf, and the embodiment of fig. 9 can stagger the knee joint part by providing the connecting portion 8, so as to improve the flexibility of the lower limb when the user wears the pressure belt, while the embodiment shown in fig. 12 adopts two separated pressure belts, so that the flexibility of wearing is further improved on the basis of fig. 9.

Similarly, for the small saphenous vein, the protrusion 2 may be disposed on the left side of the first surface 3 of the body 1 such that when the pressure band is worn by the right lower limb, the protrusion 2 is on the outside of the right lower limb and corresponds to the trend of the small saphenous vein. The bulge 2 can also be arranged for other vein trends of the lower limb, and the present disclosure is not limited by the great saphenous vein and the small saphenous vein.

Furthermore, in the post-venous return of the great saphenous vein, it is advantageous to apply a gradient of varying pressure to the great saphenous vein.

In an alternative embodiment, the first height h of at least a portion of the protuberance 2 is variable along the venous trend. Specifically, as shown in fig. 16, the first height h of at least a portion of the protrusion 2 gradually decreases from the proximal end to the distal end of the lower limb along the vein trend of the great saphenous vein, thereby exerting pressure on the vein trend gradually decreasing from the proximal end to the distal end. It should be noted that, the proximal end referred to in the present disclosure is a proximal end with respect to the heart of the human body, and the distal end is a distal end with respect to the heart of the human body, for example, for a lower limb, a thigh root or groin may be regarded as a proximal end, and an ankle may be regarded as a distal end; for the thigh, the thigh root or groin can be considered the proximal end, while the knee joint can be considered the distal end.

In other words, in particular in the first portion 6 of the body 1, the first height h of the protuberance 2 is variable and, closer to the junction of the femoral vein and the great saphenous vein, the higher the first height h of the protuberance 2 is, so as to exert a greater pressure closer to the junction of the femoral vein and the great saphenous vein. On the contrary, at the junction far away from the vein and the great saphenous vein, because the reflux blood flow in the great saphenous vein is almost not present, the pressure with the same size is not required to be applied as the junction of the femoral vein and the great saphenous vein, and the anti-gradient pressure can better promote the comfort of a user on the premise of ensuring the rehabilitation effect. It should be noted that the inverse gradient pressure is mainly because the ankle to the thigh is applied with a gradually decreasing gradient pressure, that is, a gradually decreasing gradient pressure from the distal end to the proximal end with respect to the wearing of the strap 5, and the variable protrusion 2 is applied with a gradually increasing gradient pressure from the distal end to the proximal end, and the pressure change trend is opposite to the former.

Referring again to fig. 16, in the first portion 6 of the body 1, the closer the first height h of the protrusion 2 is to the junction of the femoral vein and the great saphenous vein (right direction in fig. 16), the higher the first height h of the protrusion 2 is. Whereas in the second portion 7 of the body 1 the first height h of the protrusions 2 is the same. Alternatively, in embodiments in which the projections 2 extend along the entire length of the pressure belt, the first height H of the projections 2 may follow a variation law similar to that of fig. 16, i.e. the first height H is variable in the first portion 6 and the first height H is the same in the second portion 7.

Alternatively, the maximum value h of the first height h of the protuberance 2 _max And a minimum value h _min The difference between them is in the range of 0 to 8mm, for example 0 to 2mm, 2 to 4mm, 4 to 6mm, 6 to 8mm or 2mm, 4mm, 5mm, 6mm or 8mm.

Furthermore, the embodiment shown in fig. 14 and 15 exemplarily describes one of the embodiments in which the protrusions 2 are attached to the first surface 3. In the embodiment of fig. 14 and 15, the protrusions 2 are detachably attached to the first surface 3, and the position of the protrusions 2 at the first surface 3 is adjustable. The surface of the protrusions 2 adjacent to the first surface 3 may be provided with protruding hook and loop fasteners 13 for attachment to the first surface 3, e.g.I.e., hook and loop fasteners, end portions. Accordingly, the part of the first surface 3 for attaching the protrusions 2 comprises the corresponding +.>(i.e., hook and loop fasteners) surfaces, such as raised surfaces. Thus, the protrusion 2 may be detachably attached to the first surface 3 in a similar manner to the attachment of the strap 5 to the second surface 4, and its position is adjustable.

The adjustable and/or removable protuberance 2 has its advantages in practical applications. For example, the saphenous vein of different persons has different trends, and at the same time, since the leg circumferences of different persons are different, even the saphenous vein of the same trend, the position of the protrusion 2 needs to be adjusted adaptively for the persons with different leg circumferences. Thus, the adjustable bulge 2 has the advantage that a doctor or nurse professional can adjust the position of the bulge 2 accordingly to the great saphenous vein trend of different patients to best adapt to the great saphenous vein trend. For the detachable bulge 2, it is possible to determine in advance that the great saphenous vein of the user is to be taken and attached to the first surface 3, and then to apply the pressure belt to the lower limb of the user. Alternatively, the protrusion 2 may be pressed directly against the great saphenous vein of the user before wearing the pressure belt, attached to the first surface 3 by a mounting structure such as a protrusion hook-and-loop fastener 13, so that the protrusion 2 may be automatically attached to the first surface 3.

Alternatively, in some applications (e.g. applications for the small saphenous vein) the protuberance 2 may also be fixedly connected to the first surface 3, since the vein profiles of the small saphenous veins of different patients are substantially the same, there is no large difference, and for such fixedly-profiled veins, embodiments in which the protuberance 2 is fixedly connected to the first surface 3 may also be employed.

Removable protrusions 2 are also advantageous. Compression devices such as pressure bands or pressure socks are typically worn for a period of time after the varicose vein is healed and recovered (e.g., one week, half month, or even one month). The first week of the post-operative healing and recovery process is particularly important, so the use of the eccentric pressurized pressure bands presented by embodiments of the present disclosure can effectively assist the patient in recovery during the first week. However, the eccentric pressing for a long time is not friendly to the patient, so that the user can detach the projection 2 by himself or with the aid of a professional in the middle and late stages of the recovery phase. Alternatively, depending on the user's recovery, the user may reattach the protuberance 2 to the pressure belt again when the eccentric pressure is required again in some special cases.

In another alternative embodiment, as shown in fig. 15, the cross section of the protrusion 2' may include a combination of an arc-shaped portion 23' and a rectangular portion 24', the arc-shaped portion 23' being disposed above the rectangular portion 24' and configured to eccentrically pressurize the user. The rectangular portion 24 'has a width greater than that of the arc-shaped portion 23' so that a non-eccentric pressing portion of the skin of the user's lower limb can be brought into contact with the rectangular portion 24'. To improve the wearing comfort of the user, the joint edges between the arcuate portions 23 'and the rectangular portions 24' may be provided as smooth transitions, avoiding scratching the skin or leaving noticeable impressions on the skin.

Furthermore, the inventors have noted that in certain clinical application scenarios, it is desirable to apply point pressure to a specific location of the lower limb. For example, the application of the point pressure is particularly advantageous at a location about 2cm below the junction of the femoral vein and the great saphenous vein (hereinafter referred to as the "saphenous pressurization point"). This can significantly block the reflux of femoral venous blood to the great saphenous vein, helping recovery after varicose vein surgery, preventing venous insufficiency and deep venous thrombosis.

In addition to the exemplary embodiments set forth in the above description, the pressure belt proposed by the present disclosure may have other alternative embodiments that may be implemented. For example, the strap 5 may alternatively extend in the width direction W from only one side of the main body 1, the opposite side of the main body 1 not including the strap 5. As another example, the first width k of the protrusion 2 may be variable along the vein run.

Such alternative embodiments are exemplarily shown in fig. 17 to 20, and the same or similar features as those of the previous embodiments are not described again here. In the embodiment of fig. 17 to 20, the strap 5 extends in the width direction W from only one side of the main body 1. To attach the strap 5 to the second surface 4, the pressure band may further comprise a plurality of glue buckles 60 disposed on the second surface 4, the plurality of glue buckles 60 being specifically disposed within or near the projection region of the boss 2 on the second surface 4. The glue button 60 is fixed to the second surface 4, for example by means of stitching. The glue button 60 has a structure similar to a belt button so that the strap 5 can pass through the glue button 60 and bend back to attach to the second surface 4. Furthermore, the attachment portion 9 may be provided on the second surface 4 of the strap 5. When worn, the straps 5 pass through the glue buckles 60 and are bent back to attach to the second surface 4, the pressure of the pressure band being adjustable by the length of the straps 5 passing through the respective glue buckle 60.

Furthermore, in the present embodiment, the first width k of the protrusion 2 may be variable along the vein trend, for example, the first width k of the protrusion 2 gradually decreases along the vein trend from the proximal end to the distal end of the lower limb, thereby applying the eccentric pressure in a larger range of the proximal end position and applying the eccentric pressure in a smaller range of the distal end position. This is primarily done to allow for greater blood flow pressure at the proximal location of the vein run and lesser blood flow pressure at the distal location. Therefore, it is important for eccentric pressurization of the proximal end position to provide a larger range of application area to apply more reliable pressure to the proximal end without applying excessive pressure at the distal end position where the blood flow pressure is small, thereby reducing the pressure burden on the user while ensuring the recovery effect and improving wearing comfort.

In a further alternative embodiment shown in fig. 19 and 20, the protrusion 2 may include a plurality of dot-like projections provided thereon, which are formed in a densely arranged manner, unlike the previous embodiment. These punctiform projections are provided on the surface of the protuberance 2. These punctiform projections constitute the portion of contact with the user and thus provide a more stable pressing force when contacting the skin surface of the user's trunk or limbs.

In another aspect, the present disclosure also provides an article of apparel including a pressure band as described above. The apparel of the present disclosure may be provided in different forms. For example, brassiere type undergarments, undershirts, corset, vests, T-shirts, shoulder supports. Also for example, underpants (e.g., briefs or shorts) for preventing and treating circulatory diseases, or other forms of oedema located at the reproductive site, including but not limited to stockings, pants, sleeves, and the like. In other cases, apparel may be in the form of a garment for encircling an associated body part (e.g., a lower abdomen or chest part) and secured in place with suitable fastening devices, such as hook and loop fastening systems as previously described, or other fastening systems such as buttons and the like.
