Description

  The present invention relates to a lymphedema care product used to reduce symptoms of lymphedema.

  For cancer treatment, it is known that lymphedema and lymph leakage are likely to occur when lymph nodes are removed by surgery or radiotherapy is performed. Lymphedema refers to a state in which interstitial fluid has accumulated in the subcutaneous tissue due to a decrease in the absorption, transport, and elimination functions of lymph fluid in lymphatic vessels. Lymphatic leakage refers to a state in which lymphatic fluid leaks from a portion where the lymphatic vessel just below the skin expands and becomes a foamy bubble. Lymphedema is difficult to cure once it develops, and patients must go along with lifelong lymphedema. However, lymphedema has a significant impact on daily life, such as difficulty in walking and even simple manual labor if the symptoms become serious, and the physical and mental distress of the patient is not normal. Absent. Moreover, since regular treatment is required, the financial burden is very large.

  On the other hand, lymphedema may prevent the onset, reduce symptoms, or suppress deterioration by performing early care. Therefore, it is very important to provide appropriate care before the onset of lymphedema or at an early stage of symptoms.

  Here, according to the latest cancer statistics summary in Japan by the National Cancer Center (see Non-Patent Document 1), there are 865,238 newly diagnosed cancers (predicted national value of disease) in 2012 (503,970 males, 361,268 females) are reported. In addition, lymphedema that develops after surgery increases every year at a rate of about 2,000 in the upper limbs and about 3,500 in the lower limbs. When combined with secondary acquired by lymph node dissection, etc., it is estimated to be 150,000 to 150,000. Therefore, prevention of the onset of lymphedema and the care of the affected patients are urgent issues.

  Treatment methods for lymphedema include manual lymph drainage by a lymphedema therapist, compression therapy, exercise therapy under compression, selection of elastic clothing and guidance on wearing, skin care, and the like. Manual lymph drainage (hereinafter referred to as “drainage”) refers to gently swirling the surface of the skin with the palm in close contact with the skin, and slowly applying pressure in the direction of draining the lymph for 2-3 seconds. It is a medical massage to improve edema by flowing lymph to normal functioning lymph nodes by being stretched about once.

  However, since the effect of drainage is temporary, pressure therapy after drainage is indispensable in order to maintain the effect. Compression therapy has the effect of increasing pressure in the subcutaneous tissue and preventing leakage of lymph fluid from capillaries and retention of lymph fluid. Such compression therapy is generally performed using an elastic garment such as an elastic sleeve, an elastic glove, or an elastic stocking, or an elastic bandage.

  As a technique related to compression therapy, for example, Patent Document 1 discloses a technique for treating lymphedema having a sleeve having an elastic finger portion protruding inward and a circular band for adjustment attached to the outside. An apparatus is disclosed. The elastic finger portion applies a pressure point of a lattice pattern to the swollen limb, and is formed of a foam material that has been processed to be uneven.

  U.S. Patent No. 6,057,031 discloses a clothing article that includes at least one panel adapted to provide targeted compression, such as at least 20% of the total length of a particular surface vein in the body. The panel is located on the inside of the clothing article and is targeted to the single or multiple protrusions or pads that project inwardly toward the skin surface as they act on the body during use. It has come to provide pressure. Also, the panel is formed from cotton-like fibers, silicone, latex rubber, memory foam, polyurethane foam, stiffer plastic or metal studs, or combinations thereof.

  In Patent Document 3, a flexible base material is provided so as to be distributed over substantially the whole base material, and it is possible to seal the outside with a gas at a predetermined pressure. An affixing type therapeutic device comprising a protruding small section formed of a flexible film material is disclosed.

  Patent Document 4 has a plurality of protrusions that respectively apply local pressure to a region having accumulation of bodily fluid in the patient's body or affected by accumulation of bodily fluid, and is worn by the patient over the region. And a supporter configured to press the protrusion against the patient's body is disclosed. The protruding portion (kump) is formed by bubbles filled with gas that are held at a predetermined position between the surface layer and the back surface layer of the mesh portion (see paragraph 0031 of Patent Document 4). Alternatively, foamed plastic or the like may be used instead of bubbles (see paragraph 0034 of Patent Document 4).

  Patent Document 5 discloses a treatment of skin and saphenous tissue disorders comprising a first network (soft web) of soft material and a protruding structure integrated with the network and including a plurality of discrete protruding elements. For example, a device for repairing sports injury is disclosed. The projecting elements comprise foams that are spaced apart from one another and integrated with the first network. The foam is compressed between a first network and a second network of soft material, the two networks being bonded together between the protruding elements.

  In order to improve the symptoms of lymphedema or to suppress the progression of symptoms, it is important to maintain drainage-enhanced lymph flow and assist in the flow of lymph from superficial lymph vessels to deep lymph vessels. is there. To this end, in compression therapy, not only simply pressurizing the body surface, but also applying pressure points, such as when massaging with the fingertips of a human finger, taking into account the pressure points so that lymph flows in the appropriate direction. It is effective to keep shaking slightly.

  However, in the said patent documents 1, 2, and 5, it is only pressurizing with a protrusion etc., and the viewpoint of shaking a pressurization point is not considered.

  Hereinafter, a lymphedema care product according to an embodiment of the present invention will be described with reference to the drawings. In addition, this invention is not limited by the following embodiment. Moreover, in description of each drawing, the same code | symbol is attached | subjected and shown to the same part. The drawings referred to in the following description only schematically show shapes, sizes, ratios, and positional relationships so that the contents of the present invention can be understood. That is, the present invention is not limited only to the shape, size, ratio, and positional relationship exemplified in each drawing.

  In the present application, “care” for lymphedema is intended to include reduction of symptoms of lymphedema and the accompanying lymphatic leakage, suppression of exacerbation, and prevention, and prevention of the onset of lymphedema.

  FIG.1 and FIG.2 is a schematic diagram which shows the lymphedema care article which concerns on the 1st Embodiment of this invention. Among these, FIG. 1 shows the front side of the lymphedema care product, and FIG. 2 shows the back side of the lymphedema care product. Here, the front side of the lymphedema care product is the side facing the user when the lymphedema care product is worn. FIG. 3 is an enlarged perspective view showing a part of the lymphedema care product. FIG. 4 is an enlarged longitudinal sectional view of the lymphedema care product.

  As shown in FIG. 1, a lymphedema care product 100 according to a first embodiment of the present invention is a pad that is used by being directly or indirectly pressed against a body surface of a user, and includes a sheet 110 and the sheet. 110 and a plurality of protrusions 120 arranged in a distributed manner on one surface of 110. These protrusions 120 are brought into contact with the user's skin directly or through a thin cloth or the like, and pressurize the user's skin. Hereinafter, the lymphedema care product 100 according to the present embodiment is also referred to as a pad 100.

  The pad 100 shown in FIG. 1 has an elliptical shape or an oval shape. However, the shape of the pad 100 is not limited to this, and various shapes such as a circular shape or a rectangular shape with rounded corners can be adopted depending on the portion where the pad 100 is used. Also, the size of the sheet 110 can be appropriately determined according to the site where the pad 100 is used, the body shape of the user, the presence or absence of lymphedema, the degree (region) of onset, and the like. For example, when the pad 100 is used on the thigh rear surface, the length in the longitudinal direction is preferably about 30 cm and the length in the short direction is about 25 cm. Moreover, when using for a calf, it is good to set the length of a longitudinal direction to about 30 cm and the length of a transversal direction to about 16 cm. When used for the knee, the length in the longitudinal direction is preferably about 18 cm and the length in the short direction is about 11 cm. When used for an ankle, the length in the longitudinal direction is preferably about 17 to 23 cm, and the length in the lateral direction is preferably about 6 cm.

  The sheet 110 is formed of a resin material having flexibility that easily deforms along the shape of the user's body surface. Specifically, it is formed of elastic rubber such as natural rubber or synthetic rubber, or a material (nonwoven fabric or the like) in which fibers are knitted in a mesh shape. Among them, the silicone rubber exemplified as the material of the protrusion 120 described later has flexibility, safety that can be used by direct contact with the human body, durability that can be repeatedly washed, and the like. preferable.

  As shown in FIG. 4, the thickness t of the sheet 110 depends on the characteristics (flexibility) of the material used, but is preferably about 0.5 mm to 2 mm when silicone rubber is used. If the thickness t is smaller than this range, the durability of the pad 100 may be lowered and the pad 100 becomes difficult to handle. On the other hand, when the thickness t is thicker than this range, the user may feel uncomfortable such as wobbling at the time of wearing, and the weight may be a burden.

  A plurality of through holes 130 are formed in a region of the sheet 110 where the protrusions 120 are not formed. The through hole 130 has a diameter φ2 of about 3 mm to 9 mm, for example, and is formed by punching the sheet 110. The arrangement of the through holes 130 is not particularly limited, but may be arranged so as to be dispersed throughout the sheet 110 so as to surround the protrusions 120. The through hole 130 ensures air permeability when the pad 100 is applied to the user's skin. Moreover, since the mechanical flexibility and stretchability of the sheet 110 can be increased by providing the through hole 130, the pad 100 can be pressed along the shape of the body surface of the user, and the user Even when the pad moves, the pad 100 can easily follow the movement.

  The protrusion 120 is made of an elastic resin material, and its end surface is curved into a spherical shape or an aspherical shape. When the pad 120 is pressed against the surface of the user's body, the protrusion 120 pressurizes the pressed portion of the body surface, and maintains the pressed state while the user moves. Swing.

  The protrusion 120 preferably has hardness (softness) and elasticity close to human skin, and more preferably has hardness (same as above) and elasticity close to baby's skin. This preferably corresponds to the durometer type A having a hardness of A10 or less, more preferably A5 or less.

Moreover, it is preferable that the compression rate when the protrusion 120 is pressurized at 30 mmHg is 80% or less. In the present embodiment, the compression rate is calculated by the following equation (1) using the height of the protrusion 120 before and after compression.
Compression rate (%) = (height before compression−height after compression) / height before compression × 100 (1)
30 mmHg is a pressure used as a reference for pressurization in compression therapy, and a general elastic garment is also manufactured based on 30 mmHg. When the compression rate is too high, the protrusion 120 is almost crushed when the protrusion 120 is pressed against the body surface, and there is a possibility that it is difficult to swing.

  As shown in FIG. 4, in the present embodiment, the shape of the protrusion 120 is hemispherical, but is not limited to this. 5 and 6 are enlarged longitudinal sectional views showing modified examples of the shape of the protrusions. For example, the shape of the protrusion may be a sphere that is smaller than the hemisphere. Moreover, it is good also as a shape which connected the spherical notch to the one bottom face of a cylinder like the projection body 121 shown in FIG. Or it is good also as a shape which connected the ball | bowl piece to the upper base of the truncated cone like the projection body 122 shown in FIG.

  The advantage of curving the end face of the protrusion 120 is as follows. That is, when the pad 100 is applied to the body surface of the user and pressed with equal force from the back side of the pad 100, if the end surface of the protrusion 120 is curved, the repulsive force in one protrusion 120, in other words, And the force which presses a body surface changes with the part in the end surface of the protrusion 120. FIG. Specifically, the repulsive force (that is, the pressing force) at the vertex of the end face is the largest, and gradually decreases as the distance from the vertex increases. Therefore, in the portion of the body surface against which each protrusion 120 is pressed, an action is caused such that the lymph fluid is swept away from the apex toward the periphery.

  In addition, when the end face of the protrusion 120 is curved, the apex of the protrusion 120 is difficult to shift with respect to the part (pressing point) of the body surface once applied. Therefore, when the user moves, the apex of the protrusion 120 and the pressing point move together, and this causes the entire protrusion 120 to swing together with the elasticity of the protrusion 120, so that the user's body It will give vibration to the surface. In other words, by curving the end face of the protrusion 120, the protrusion 120 applied to the user's body surface can be stroked at a substantially constant pressure without being substantially separated from the body surface, or can be applied to the body surface. A massage action that gently shakes and pressurizes while shaking.

  The diameter φ1 at the base end portion of each protrusion 120 is preferably about 7 mm to 13 mm. When the diameter φ1 is smaller than the above range, the pressure that the user receives from the protrusion 120 may be too strong. On the other hand, when the diameter φ1 is larger than the above range, the pressure received by the user from the protrusions 120 is easily dispersed, and the distance between the tips of the protrusions 120 that serve as a pressing point against the user's skin is too far apart. Therefore, there is a possibility that the action of promoting the flow of lymph fluid is not sufficiently exhibited by the plurality of protrusions 120.

  The height (the height when measured from the surface on the back side of the sheet 110) h of each protrusion 120 is preferably about 3 mm to 7 mm. Although depending on the ratio to the diameter φ1, when the height h is lower than the above range, the height when compressed is too low, and the above-described massage action may not be sufficiently exhibited. On the other hand, when the height h is higher than the above range, the pressure on the user's body surface may become too strong. In this embodiment, the protrusion 120 has a substantially hemispherical shape having a diameter of about 11 mm and a height of about 5 mm.

  Here, the height h of the protrusions 120 need not be uniform among all the protrusions 120. By mixing a plurality of types of protrusions 120 having different heights, the surface of the pad 100 (the surface where the vertices of the protrusions 120 are connected) has a fine unevenness as a whole. Can be pressurized. In this case, the height h of the protrusion 120 may be changed within a range of about 3 mm to about 7 mm, for example.

  The distance d between adjacent protrusions 120 is preferably about 2 mm to 15 mm. More preferably, the distance d is set to be not less than the radius (φ1 / 2) of the protrusion 120 and not more than the diameter φ1. When the distance d is narrower than the above range, rather than the individual protrusions 120 pressurizing the user's body surface, the protrusions 120 are pressed into a planar shape and the lymph fluid flow is promoted. May be reduced. Further, there is no space for providing the through hole 130. On the other hand, when the distance d is wider than the above range, the distance between the tips of the protrusions 120 serving as pressing points to the body surface is too far away, and the effect of promoting the flow of lymph is not sufficiently exhibited. There is a fear.

  As a material for the protrusion 120, it is preferable to use soft elastic rubber such as natural rubber or synthetic rubber. In particular, the silicone rubber has flexibility and elasticity that can continue to press the user's skin with a moderately constant force. Silicone rubber has an advantage that flexibility and elasticity can be controlled by adjusting the amount of silicone oil to be blended. Furthermore, since silicone rubber is recognized for its high safety, it is used in the medical field and the food field, and is a material that is gentle to the skin. It can also be used continuously for a long time in contact with the skin. In addition, silicone rubber has durability that can withstand repeated use, and since there is little change in physical properties due to temperature, it can maintain a constant pressing force even if the user's body temperature changes, and is strong against washing Since there is an advantage that it can be used in a sanitary manner, it is suitable as a material for the protrusion 120 and the sheet 110.

  The sheet 110 and the protrusions 120 may be integrally formed at the same time, or the sheet 110 may be integrated later with respect to the protrusions 120 separately manufactured. In the latter case, the composition of the sheet 110 and the protrusion 120 is not necessarily the same.

  Next, a preferable arrangement of the protrusions 120 will be described. 7 to 9 are schematic diagrams for explaining the flow of lymph in the thigh. 7 shows the front thigh, FIG. 8 shows the rear thigh, and FIG. 9 shows the thigh side. FIG. 10 is a schematic diagram for explaining a preferable arrangement of the protrusions 120.

  The superficial lymphatic system has an attribute, and in a large lymphatic vessel such as a collecting lymphatic vessel, it is determined which lymphatic fluid flowing through which lymphatic vessel enters which lymph node. In addition, at positions such as the left and right centers of the body, the height of the umbilicus, the height of the clavicle, a boundary line that draws less connection between the collecting tubes is drawn. This boundary is called lymphatic basin. Normally, it is difficult for the lymph fluid to flow over the lymphatic basin, and the lymph fluid flows into the collecting lymphatics through the capillary lymphatics from the gaps between the tissues in each region divided by the lymphatic basin. To the lymph node to which it belongs. Furthermore, the lymph fluid is carried deeper in the body (subfascia) and flows into the left and right supraclavicular fossa through the deep lymphatic vessels.

  Therefore, if lymphedema is caused by dissection of a lymph node in a certain area, the flow of lymph fluid can be encouraged to flow from that area to the lymph node belonging to another area, beyond the lymphatic basin. Can improve the symptoms of lymphedema. Since the lymph nodes are dissected in this area, even if the lymph fluid cannot be drained from the collecting lymph vessels belonging to this lymph node, the lymph fluid can be passed through the capillary lymph vessels directly under the skin so as to cross the lymph basin. By facilitating the flow, the lymph can flow into the collecting lymphatics belonging to another lymph node.

  For example, normally, on the front surface 13 of the thigh, the lymph fluid flows into the inguinal lymph node 10 by promoting the flow of the lymph fluid from the lower side to the upper side (from the terminal side to the inguinal side). However, when the inguinal lymph node 10 is dissected by uterine cancer treatment or the like, the lymph fluid cannot flow into the inguinal lymph node 10. Therefore, in this case, as shown in FIG. 7, the flow of the lymph fluid is not simply promoted from the lower side to the upper side toward the groin, but the thigh inner part 11 is changed to the outer thigh part as shown by the arrow in the figure. 12, the flow of the lymph fluid is promoted in an oblique direction so that the lymph fluid flows outside the pelvis. At this time, if a flow toward the dorsal lymph node and axillary lymph node occurs in the pelvic part, the lymph fluid flows out, and the pressure in the lymph vessel in the pelvic part decreases. As a result, the lymph fluid flowing from the thigh direction is pushed out, passes over the lymphatic varicella and flows into the axillary lymph node via the dorsal lymph node. Similarly, as shown in FIG. 8, also on the rear thigh surface 14, the flow of lymph fluid is promoted in an oblique direction from the popliteal 15 side toward the buttocks 16 side and from the inner thigh portion 11 toward the outer thigh portion 12. When viewed from the side of the thigh, as shown in FIG. 9, the flow of lymph fluid so as to be lifted obliquely from below to above from the inner thigh 11 to the outer thigh 12 through the rear thigh 14. Is prompted.

  Here, capillary lymphatic vessels at the end of lymph in the superficial lymphatic vessels existing directly under the skin are very finely branched and stretched in a mesh form in subcutaneous fat. Moreover, since the capillary lymphatic vessel does not have a valve structure, the lymphatic fluid flows in any direction. Therefore, in the present embodiment, in consideration of such characteristics of the capillary lymph vessel, the protrusion 120 is arranged so that the lymph fluid easily flows in the necessary direction in the capillary lymph vessel. Specifically, as shown in FIG. 10, a group of protrusions arranged in a line along the longitudinal direction, and a group of protrusions arranged in a line so as to be oblique to the protrusions And are provided. As a result, the flow of lymph fluid can be promoted at the position of each protrusion 120, and the promoted lymph fluid flow can be promoted in a specific direction, for example, from the bottom to the top in the figure and from the bottom left to the top right in the figure. You can urge in the direction you head.

  11 and 12 are schematic diagrams for explaining a further arrangement method of the protrusions 120. FIG. The protrusions 120 may be arranged irregularly after being regularly arranged as described above. Specifically, the periphery of the protrusion 120 located at the intersection of the row of the protrusions 120 arranged in the longitudinal direction of the pad 100 and the row of the protrusions 120 arranged in the oblique direction does not approach the radius r of the protrusion 120. In addition, the protrusions 120 are sequentially arranged in a range that is not separated from the diameter 2r of the protrusions 120. In other words, a concentric circle having a radius r, a concentric circle having a radius 2r, and a concentric circle having a radius 3r are drawn around the center point O of a certain protrusion 120, and on a region S surrounded by a concentric circle having a radius 2r and a concentric circle having a radius 3r, The protrusion 120 is disposed. The position of the protrusion 120 is not limited as long as it is on the region S, and may be, for example, a position in contact with the inner circumferential circle of the region S (see the protrusion 120a) or a position where a part of the region S is applied (see the protrusion 120b) Or a position in contact with the outer circumference circle of the region S (see the protrusion 120c). When the position of the new protrusion 120 (see the protrusions 120a to 120c) is determined in this way, the position of the next protrusion 120 is similarly determined based on the center point O. Thereby, as shown in FIG. 12, the irregular arrangement | positioning of the protrusion 120 can be formed.

  As described above, by disposing the protrusions 120 irregularly between the protrusions 120 that are regularly arranged in consideration of the direction in which the lymph fluid flows, it is possible to further promote the dispersed flow of the lymph fluid. It becomes.

  Note that the arrangement of the protrusions 120 is not necessarily limited, and may be randomly dispersed. In this case, the interval between the adjacent protrusions 120 is preferably not less than the radius of the protrusion 120 and not more than the diameter of the protrusion 120. Even in this case, a massage action can be obtained by the shape and elasticity of the protrusion 120 described above.

  Next, a method for using the pad 100 will be described. FIG. 13 is a schematic diagram for explaining how to use the pad 100. For example, when the pad 100 is applied to the thigh rear surface 14, the arrangement surface of the protrusion 120 is directed to the body side, the pad 100 is applied to the thigh rear surface 14 directly or through a thin cloth (nonwoven fabric, etc.), and a vantage is wound. The pad 100 is fixed. Thereby, the flow of the lymph fluid (refer to the arrow in the drawing) from the lower side to the upper side of the drawing and from the inner thigh portion 11 to the outer thigh portion 12 can be promoted.

  FIG. 14 is a schematic diagram for explaining another method of using the pad 100. When the pad 100 is applied to the calf 20, the arrangement surface of the protrusion 120 is directed to the body side, and the pad 100 is applied to the calf 20 directly or through a thin cloth. Then, the pad 100 is fixed by winding a vantage or the like. Thereby, the flow (refer to the arrow in the figure) of causing the lymph fluid of the lower leg to flow obliquely upward from the left and right of the calf 20 and flowing into the popliteal lymph node 21 can be promoted.

  As described above, according to the first embodiment of the present invention, when the pad 100 is pressed against the body surface of the user, each projection 120 is used while pressing the pressed portion. Since it swings with the movement of the person, it is possible to continue to apply vibration or shaking to the pressurizing point, and to promote the flow of lymph. Further, according to the first embodiment of the present invention, by arranging the protrusions 120 in a predetermined arrangement, the flow of lymph fluid in a specific direction is promoted in combination with the swing of the individual protrusions 120. can do. Therefore, the symptoms of lymphedema can be reduced or the progression of symptoms can be suppressed. Alternatively, when lymphedema has not yet developed, it may be possible to prevent the onset.

  In addition, according to the first embodiment of the present invention, since the plurality of through holes 130 are formed in the sheet 110, air permeability can be ensured.
