Description

  The present invention relates to a protective pad for preventing the occurrence of pressure ulcers at sites such as heels and knees.

  Conventionally, a protective pad for preventing the occurrence of pressure ulcers or the like or protecting a pressure ulcer site is known. For example, Patent Document 1 discloses a protective pad having a boot shape including a space for inserting a portion centered on a wearer's heel, a cushion material positioned in the space, and a pair of fastening portions. Has been.

Special table 2009-508625

  According to the protective pad disclosed in Patent Document 1, since the part centered on the wearer's heel is protected by the pad, it is necessary to maintain a supine state for a relatively long period of time in the field of medical treatment or nursing care. In this case, it is possible to prevent the portion from rubbing the floor (decubitus).

  However, since the pad has a uniform thickness, the pad deforms along the shape of each wearer's heel and does not fit in the space, causing a shift in the space, or due to the weight of the protected part. There is a possibility that the deformed shape of the crushed part is not constant and the body pressure of the part cannot be reduced stably.

  An object of the present invention is an improvement of the conventional technique, in which a central area of a panel member can be deformed and fitted along a shape of a bending portion such as a wearer's heel, and a pressure ulcer is generated at the site. It is in the provision of a protective pad that can reliably prevent the above.

  In order to solve the above problems, the present invention provides a pad having a vertical axis and a horizontal axis, and having a skin facing surface and a non-skin facing surface, first and second end edges, and first and second side edges. A main body and fastening means having a locking flap extending from at least one of the first and second side edges of the pad main body to the outside in the lateral direction and having a fastening element located on the skin facing surface. Includes protective pads.

  In the present invention, the pad body includes a first end region located on the first end edge side, a second end region located on the second end edge side, and a center located between the first and second end regions. A panel member that is divided into regions, the panel member having both side notches located in the center region, a center recess located between the both side notches in the lateral direction, and the direction of the longitudinal axis. It has the 1st elastic element which extends and crosses a notch part on both sides, It is characterized by the above-mentioned.

  According to the protective pad according to the present invention, the notch portions on both sides of the panel member are located, and the first elastic element extending in the longitudinal direction Y and intersecting with the first elastic element is disposed. The central region of the panel member is curved along the shape of the joint part (protruding part) of the wearer and fits to the part. As described above, since the central area of the panel member fits in the part and the central concave part is located opposite to the tip part of the part, floor rubbing (decubitus) is caused by the tip part directly touching the contact surface. Can be prevented.

1 and 2, a protective pad 10 according to the present invention has a longitudinal direction Y and a lateral direction X orthogonal thereto, a skin facing surface and a non-skin facing surface on the opposite side, and is a rectangular pad. It has a main body 11 and fastening means 12 for attaching the pad main body 11 to the wearer's body. The protective pad 10 further has a vertical axis P that bisects the dimension of the pad main body 11 in the horizontal direction X, and a horizontal axis Q that is orthogonal to it and bisects the dimension of the pad main body in the vertical direction Y. . The protective pad 10 is intended to protect the joints such as the wearer's heel, elbows, and knees. For example, when the joints are lying on a futon or bed for a long period of time, such as a futon, It is possible to prevent floor rubbing (decubitus) from coming into direct contact with the contact surface 13 such as a bed.

  The pad body 11 includes first and second end edges 11a and 11b extending in the horizontal direction X so as to be spaced apart from each other in the vertical direction Y, and first and second edges extending in the vertical direction Y so as to be spaced apart from each other in the horizontal direction X. An outline of the pad main body 11 is demarcated from the side edges 11c and 11d, and is interposed between an inner sheet 15 that forms a skin facing surface, an outer sheet 16 that forms a non-skin facing surface, and inner and outer sheets 15, 16. Panel member 17.

  The fastening means 12 is a first fastening means composed of a pair of locking flaps (first and second locking flaps) 18A, 19A and receiving flaps (first and second receiving flaps) 18B, 19B. 21 and second fastening means 22. More specifically, the first fastening means 21 includes a locking flap 18A extending from the first side edge 11c of the pad body 11 outward in the lateral direction, and an outer side in the lateral direction X from the second side edge 11d of the pad body 11. And a receiving flap 18B extending to The second fastening means 22 includes a receiving flap 19B that extends outward in the lateral direction X from the first side edge 11c of the pad main body 11, and a locking flap 19A that extends outward in the lateral direction X from the second side edge 11d. The Fastener tabs 23 having fastening elements 24 arranged on the skin facing surface are connected to the outer portions of the respective locking flaps 18A, 19A in the lateral direction X.

  Between the inner sheet 15 and the outer sheet 16, a leak-proof sheet 26 formed from a liquid-impermeable and moisture-permeable plastic film is disposed. The inner sheet 15 and the outer sheet 16 are fixed via a hot melt adhesive (not shown) applied to the inner surface of either one of the sheets 15 and 16. In addition, a pair of barrier sheets 27 symmetric with respect to the vertical axis P are attached to the outer side of the panel member 17 on the skin facing surface of the pad body 11 in the direction of the horizontal axis Q.

  The pad main body 11 further includes end flaps 29 that face each other in the vertical direction Y and extend in the horizontal direction X, and side flaps 30 that face each other in the horizontal direction X and extend in the vertical direction Y. The end flap 29 is formed by superimposing an inner sheet 15, a leak-proof sheet 26, an outer sheet 16, and a barrier sheet 27 that extend outward in the longitudinal direction Y from both end edges of the panel member 17. ing. Further, the side flaps 30 extend from both side edges of the panel member 17 to the outside in the lateral direction X, and the inner sheet 15, the leak-proof sheet 26, the outer sheet 16 and the barrier sheet 27 are overlapped with each other. It is formed.

The inner surface sheet 15 is a fiber nonwoven fabric sheet having a required flexibility, preferably hydrophilized, and having a liquid permeability of a mass of about 15 to 35 g / m ^2. For example, a spunbond fiber nonwoven fabric, a point bond It can form from various well-known fiber nonwoven fabrics, such as a fiber nonwoven fabric and an air through nonwoven fabric. The outer surface sheet 16 is a substantially liquid-impervious SMS (spunbond / meltblown / spunbond) non-woven fabric, a spunbond non-woven fabric, a plastic sheet, or at least one of these non-woven fabrics having a mass of about 15-30 g / m ^2. It can be formed from a laminate sheet. As will be described later, when the fastening element 24 (the hook group of the mechanical fastener) of the fastener tab 23 is directly fixed to the outer surface of the outer sheet 16, the outer sheet 16 has a required strength with which the fastening element 24 can be engaged. It is preferable to form with well-known fiber nonwoven fabrics, such as a spun bond fiber nonwoven fabric and an air through fiber nonwoven fabric. Moreover, in order to reduce the frictional resistance between the outer surface sheet 16 and the contact surface 13, a low friction film may be attached to the outer surface of the outer surface sheet 16, or a silicon resin may be applied.

  The panel member 17 includes a semi-rigid panel-shaped core member 32 having a higher rigidity than the sheet members such as the inner and outer surface sheets 15 and 16, and a wrap sheet 33 that encloses the core member 32. The core material 32 has a required compression elasticity (cushioning property), and is mainly formed from an absorbent fiber such as fluff pulp. As an option, the superabsorbent polymer particles are used to increase the absorption rate of body fluid. (SAP) may be included, or an elastic member such as rubber or urethane foam may be mixed in order to increase the compression elasticity of the entire panel member 17. The wrap sheet 33 can be formed of tissue paper, hydrophilic fiber nonwoven fabric, hydrophilic treated hydrophobic fiber nonwoven fabric, porous plastic film, or a laminate sheet formed by laminating these. The wrap sheet 33 has a function of maintaining the shape of the core material 32 and preventing the core material 32 from falling off when the core material contains superabsorbent polymer particles.

  The panel member 17 is positioned so as to intersect with the vertical axis P and the horizontal axis Q, and is positioned on both sides of the central concave portion 34 having a substantially rounded rectangular shape that is slightly long in the vertical direction Y passing through the panel member 17. And both side cutout portions 35. Both side notches 35 are substantially V-shaped and gradually narrower toward the vertical axis P, and their tip portions are located in the vicinity of the outer peripheral edge of the central recess 34. The center recess 34 may have a bottom with a part thereof remaining without penetrating the panel member as long as the effects of the present invention to be described later are obtained, and in addition to the rounded rectangle, an ellipse, a triangle It may be a polygonal shape or the like.

The leak-proof sheet 26 can be formed from a liquid-impermeable SMS fiber nonwoven fabric, a spunbond fiber nonwoven fabric, a polyethylene plastic sheet, or a laminate sheet thereof having a mass per unit area of about 10 to 30 g / m ^2. . The barrier sheet 27 includes a proximal edge 57 that forms part of the side flap 30, first and second fixed ends 58 and 59 that form part of the end flap 29, and first and second fixed ends. And a distal edge 60 formed by folding the inner edge of the barrier sheet 27 inwardly, extending in the longitudinal direction Y between the parts 58 and 59. A single strand-like or string-like cuff elastic element 36 extending in the longitudinal direction Y is disposed on the distal edge 60 so as to be contractible. When the pad main body 11 is worn, the distal edge 60 is separated from the skin facing surface of the inner sheet 15 by the contraction action of the cuff elastic element 36 and closely contacts the wearer's body.

  The locking flaps 18A and 19A have a substantially trapezoidal shape, and include a fixing portion attached to the pad body 11, an extension portion extending from the fixing portion to the outside in the lateral direction X, and a fastener tab 23 attached to the tip. Have The locking flaps 18A and 19A are preferably stretchable, and are a non-stretchable SMS fiber nonwoven fabric or a spunbond fiber nonwoven fabric, or a strand shape extending in the transverse direction X between the plurality of nonstretchable fiber nonwoven fabrics. Or it can form from the sheet | seat member which consists of a sheet | seat material which has a stretching property at least in the horizontal direction X by arrange | positioning a string-like elastic element, or one sheet or several elastic sheets. The fastener tab 23 is formed in a tape shape from a relatively rigid sheet material such as a plastic film, a fiber nonwoven fabric, a laminate thereof, or kraft paper. The fastening elements 24 located on the skin facing surface side of the fastener tab 23 are hooks of mechanical fasteners, and are fastened to a receiving flap or / and an outer surface sheet facing each other in the lateral direction X so as to be detachable. . The locking flaps 18A and 19A may not have a fastener surface, and the fastening element 24 may be disposed directly on the locking flaps 18A and 19A.

  The receiving flaps 18B and 19B have a substantially trapezoidal shape that protrudes outward in the lateral direction X, and extends to the outside in the lateral direction X from the fixed portion connected to the outer surface of the outer sheet 16. And an exit. The receiving flaps 18B and 19B can be formed from various known fiber nonwoven fabrics such as non-stretchable SMS fiber nonwoven fabrics and spunbond fiber nonwoven fabrics, plastic films, and the like. In order to improve the engagement of the fastening element 24, a receiving sheet piece (target tape) having a loop group of mechanical fasteners may be arranged on the outer surface. The fastening element 24 may be applied with an adhesive such as a pressure sensitive adhesive in addition to the loop group of mechanical fasteners. In this case, the receiving flaps 18B and 19B and / or the outer sheet 16 are In order to improve the adhesive strength of the pressure-sensitive adhesive, it is preferably formed from a plastic film having a smoother surface than the fiber nonwoven fabric. As shown in FIG. 1, the protective pad 10 is attached to the wearer's body by fastening the locking flaps 18A and 19A to the receiving flaps 18B and 19B, and a space for protecting the affected part in the inside thereof. A part is defined.

  Referring to FIGS. 3 and 4, the panel member 17 includes a first elastic element 41 extending in the longitudinal direction Y intersecting with the both side notches 35, and a plurality of strips extending in the longitudinal direction Y intersecting the central recess 34. Two elastic elements 42 are shrinkably attached between the leak-proof sheet 26 and the outer sheet 16 via a hot melt adhesive (not shown). Further, a plurality of strand-like or string-like third elastic elements 43 extending in the longitudinal direction Y are disposed on the outer sides in the lateral direction X on both side edges of the leak-proof sheet 26, and the proximal edge 57 of the barrier sheet 27 and the outer sheet. It attaches so that shrinkage | contraction is possible via a hot-melt-adhesive (not shown) between 16 both sides. In this embodiment, although the length dimension in the vertical direction Y of the 1st and 2nd elastic elements 41 and 42 is substantially the same, the length dimension concerning this may differ. Since the 1st and 2nd elastic elements 41 and 42 are arrange | positioned between the leak-proof sheet | seat 26 and the outer surface sheet 16, when located between the inner surface sheet 15 and the panel member 17 which are located in the skin opposing surface side Compared to the above, when the extension stress of the first and second elastic elements 41, 42 does not directly act on the wearer's skin, and the first and second elastic elements 41, 42 exhibit a relatively large extension stress. Even so, there will be no pressure marks on the skin.

  For convenience of explanation, the panel member 17 includes a central area 45 in which the first and second elastic elements 41 and 42 are disposed, a first end area 46 located on the first end edge 11a side from the central area 45, and a central area. The region 45 is divided into a second end region 47 located on the second end edge 11b side.

  6 and 7, in the state where the protective pad 10 is attached to the leg of the wearer who is supine, the panel member 17 is centered by the opposing edges of the side cutouts 35 approaching and / or abutting each other. The concave portion 34 is deformed into a curved shape so as to face the heel 50 and fits to the wearer's leg H. The wearer's heel is in a state of being separated from the contact surface 13 of the protective pad 10 such as a floor surface, and is not in direct contact with the contact surface 13. Specifically, the height dimension r of the outer peripheral edge of the central recessed portion 34 is about 0.3 to 1.0 cm in a state where the panel member 17 is loaded with a heel load. In this aspect, since the flange is positioned so as to fit into the central recess, the flange 50 is fixed between the central recesses 34, and the flange 50 contacts the contact surface 13 for a relatively long time. The floor rubbing (decubitus) that occurs can be prevented. Moreover, since the panel member 17 which contacts the heel 50 has a required compression elasticity (cushioning property), the body pressure applied to the heel can be reduced, and pressure ulcer occurs at the contact portion between the heel 50 and the panel member 17. Can be prevented.

  Further, since the panel member 17 is mainly formed from fluff pulp which is an absorbent fiber, the panel member 17 has a required absorbability, for example, absorbs bodily fluid that exudes from pressure ulcers when the pressure ulcer 50 causes pressure ulcers. can do. Therefore, the pressure ulcer part of the heel 50 is not left in a wet state for a long time with the body fluid exuded, and further deterioration of the pressure ulcer can be prevented. Referring to FIG. 1, a locking flap 18 </ b> A constituting the first and second fastening means 21, 22 covers a portion projecting near the base of the toe (a portion having a wedge-shaped bone) and an ankle so as to cover them. Since 19A and the receiving flaps 18B and 19B are located in a state where they overlap each other, even if the wearer is lying down or lying down, these projecting parts cannot directly touch the contact surface 13 And the occurrence of pressure ulcer can be prevented. When the locking flaps 18A, 19A are formed from a stretchable sheet material such as a stretchable nonwoven fabric, the stretch flaps 18A and 19A are stretched according to the outer peripheral dimensions of the portion to be covered. In this case, the protective pad 10 can be stably mounted, and the protruding portion can be protected.

In order to achieve the above effects, in the panel member 17, the central recess 34 is preferably circular or elliptical with a diameter of about 20 to 50 mm. The protective pad 10 is used for a part of the wearer's body that may cause pressure ulcers such as a joint part, for example, a heel, an elbow, a knee, etc., and these parts all have a curved shape. This is because the central recess 34 preferably has a size and shape along its outer shape. Moreover, it is preferable that the mass of the fluff pulp of the panel member 17 is about 300-800 g / m < ² >. In the case of 800 g / m ² or more, fluff pulp is pressed into a panel shape and has a relatively high rigidity, and the cushioning property may be lowered.

  The pad member 17 is provided with both side notch portions 35 and the first elastic elements 41 are arranged so as to intersect the both side notch portions 35. As a result of the approaching and / or contact, the spaced-apart portion becomes narrower. Thus, the dimension of the vertical direction Y in the site | part in which the 1st elastic element 41 is arrange | positioned becomes small, Therefore The dimension of the vertical direction Y between the site | parts in which the 1st elastic element 41 by the side of the center recessed part 34 is not arrange | positioned. The outer part where the first elastic element 41 is arranged due to the difference is curved. Since the outer portion has a curved shape and is positioned so that the ridge fits into the central recess 34, the panel member 17 is deformed to cover the entire ridge. Further, the second elastic element 42 is disposed in the central recess 34, and the second elastic element 42 expands and contracts depending on the size of the flange fitted into the central recess 34, so that the vicinity of the opening edge of the central recess 34 is the flange 50. It fits so that the front-end | tip part 50a may be wrapped. Therefore, the panel member 17 can be deformed so as to cover the entire heel of various sizes and shapes with different curvatures, and the tip of the heel 50 can be used even when the wearer is sleeping in different positions. Each part such as the part 50a, both sides, and the rear end does not directly touch the contact surface 13, and the occurrence of pressure ulcer can be prevented.

  In the first elastic element 41, in order to further deform the panel member 17 into a curved shape along the shape of the wearer's heel, an elastic element having a high stretching force is arranged toward the outside in the lateral direction X, or the most horizontal The elastic force of the elastic element located outside the direction X can be made higher than other elastic elements. Further, by arranging the third elastic element 43 in the side flap 30 located outside the lateral direction X of the panel member 17, the entire protective pad 10 can be curved so as to cover the entire leg portion. . Since the side flaps 30 are less rigid than the panel member 17, it can be said that the side flaps 30 are more likely to bend along the shape of the legs due to the expansion and contraction action of the third elastic element 43, and can be said to have high fit. Thus, since the entire protection pad 10 expands and contracts along the size and shape of the leg, for example, even when the shape of the part to be protected changes due to the movement of the joint when bending the elbow or bending the knee, It can be deformed according to its shape change. When the protective pad 10 is attached to a part with a pressure ulcer, the affected part is protected by the entire protective pad 10, so that the side flap 30 becomes a barrier and exudes from the pressure ulcer that was not absorbed by the protective pad 10 due to a change in body position or the like. It is possible to prevent leaked body fluid from leaking outside.

  In the fastening means 12, the locking flap 18A of the first fastening means 21 is attached to the first side edge 11c side of the pad body 11, and the locking flap 19A of the second fastening means 22 is the second side edge 11d of the pad body 11. The positions of the locking flaps 18A and 19A are arranged symmetrically with respect to the vertical axis P and the horizontal axis Q. Therefore, for example, the aspect of the fastening means 12 is illustrated even when the protective pad is rotated 180 degrees from the illustrated aspect and attached to the wearer's body with the second end edge 11b side on the toe side. This is the same as the embodiment. Therefore, the protective pad 10 can be used for both the wearer's legs and arms.

  In the present embodiment, when the wearer wears the protective pad 10, any one of the leak-proof sheet 26 and the outer sheet 16 so that the central recess 34 can be positioned more easily against the heel or the affected part. You may attach a color to. By attaching colors to these sheets, when the wearer and / or the wearer looks at the panel member 17 from the inner surface side of the protective pad 10, the colors are only present at the positions where the both side notches 35 and the central recesses 34 are arranged. This is because the position and size can be easily confirmed.

Second Embodiment
Referring to FIG. 8, in the present embodiment, the panel member 17 includes a first panel member 51 and a second panel member 52 that are opposed to each other in the vertical direction Y via the horizontal axis Q. The first panel member 51 and the second panel member 52 have the same shape and the same size, and the opposing edges 51a and 52a have a concavely curved portion located at the center, and both sides of the concavely curved portion are in the lateral direction X. It has the shape which inclines to the outer side of the vertical direction Y as it goes outside. Both side notch portions 35 and the central recess portion 34 are defined in the space between the opposing edges of the first and second panel members 51, 52, and the both side notch portions 35 and the center recess portion 34 communicate with each other. Also in the present embodiment, the central region 45 of the panel member 17 is deformed along the shape of the ridge by the contraction action of the first and second elastic elements, and the first panel member 51 and the second panel member 52 are the same. Since the shape is the same, there is no distinction between up and down and front and back, and any of the first and second end edges 11a and 11b may be used on the toe side. In addition, since the both side notches 35 and the central recess 34 communicate with each other, the size of the spaced-apart portion is made to be the shape and size of the protruding portion of the wearer by the expansion and contraction action of the first and second elastic elements 41 and 42. Therefore, the central region 45 is fitted to a protruding portion having a larger size than that of the first embodiment, in particular, a relatively large outer dimension, and is held away from the contact surface 13. In addition, the occurrence of pressure ulcer can be prevented.

  Further, in the manufacturing process of the protective pad 10, the first and second panel members 51 and 52 have the same shape and the same size. Therefore, the both side notches 35 and the central recess 34 are defined by assembling the same shape pad members. can do. Therefore, as in the first embodiment, the manufacturing process is simplified and the manufacturing cost is reduced as compared with the case where the single panel member 17 is processed to form both the notches 34 and the central recess 35. be able to.
