JP 2003-10236 A

  The contact material is usually made of a hydrophilic material so as to easily absorb body fluid. However, when a drug containing an oily component is applied to the surface of the addressing material made of a hydrophilic material, the oily component hardly enters the inside of the addressing material, and therefore remains on the surface of the addressing material forever, causing stickiness. In addition, when the oil component is pressed against the skin and the oil component spreads over the surface of the material and covers the entire surface, the body fluid cannot pass through the oil component layer formed on the entire surface of the material. In that case, the function of absorbing the bodily fluid of the addressing material is inhibited, and as a result, the bodily fluid leaks.

  An object of the present invention is to provide a bodily fluid absorbing material that has excellent usability and can prevent leakage of bodily fluids.

  The body fluid absorbing material according to the first aspect has a contact surface with the skin, and is used when a drug containing an oily component is applied to the skin. The said addressing material is provided with a lipophilic layer and a hydrophilic layer. The oleophilic layer is made of an oleophilic material and constitutes the contact surface or is disposed close to the contact surface. The hydrophilic layer is made of a hydrophilic material, and is disposed on the opposite side of the contact surface with respect to the lipophilic layer.

  The addressing material for absorbing bodily fluids according to the second aspect is the addressing material according to the first aspect, and the lipophilic layer is made of lipophilic fibers.

  The bodily fluid absorbent article according to the third aspect includes a bodily fluid absorbing material according to the first aspect or the second aspect, and a sheet material including an adhesive layer attached to the skin. The addressing material is disposed on a part of the surface of the sheet material on the skin side so that the addressing material contacts the skin in a state where the adhesive layer is attached to the skin.

  The bodily fluid absorbent article according to a fourth aspect is the bodily fluid absorbent article according to the third aspect, wherein the sheet material further includes a sheet body made of a hydrophobic material. The sheet body is disposed on the opposite side of the skin with respect to the adhesive layer.

  The bodily fluid absorbent article according to the fifth aspect is the bodily fluid absorbent article according to the fourth aspect, wherein a groove pattern including a plurality of grooves is formed on the skin side surface of the sheet material.

  A bodily fluid absorbent article according to a sixth aspect is the bodily fluid absorbent article according to the fifth aspect, wherein the groove pattern includes a plurality of first grooves extending substantially parallel to each other.

  The bodily fluid absorbent article according to a seventh aspect is the bodily fluid absorbent article according to the sixth aspect, wherein the groove pattern further includes a plurality of second grooves extending so as to intersect the first groove.

  The bodily fluid absorbent article according to an eighth aspect is the bodily fluid absorbent article according to the seventh aspect, wherein the second groove extends so as to be substantially orthogonal to the first groove.

  A package product according to a ninth aspect includes the bodily fluid absorbing material according to the first aspect or the second aspect, and a drug containing the oil component to be applied to the skin or the contact surface.

  ADVANTAGE OF THE INVENTION According to this invention, the contact material for body fluid absorption used when the chemical | medical agent containing an oil-based component is apply | coated to skin is provided. Here, the contact surface of the contact material with the skin or a portion in the vicinity thereof is constituted by a lipophilic layer made of a lipophilic material. As a result, the oily component applied to the contact surface of the contact material with the skin can enter the lipophilic layer without remaining on the contact surface indefinitely. Thereby, the stickiness of the surface of the addressing material is suppressed, and the usability is improved. Furthermore, since the oil component is prevented from spreading over the entire surface of the material, leakage of body fluid can be prevented.

<1. Overall Configuration of Body Fluid Absorbing Article>
The whole block diagram of the bodily fluid absorption article 1 which concerns on FIGS. 1-3 at this embodiment is shown. 1 and 2 are plan views of the body fluid absorbent article 1, and FIG. 3 is a side view thereof. As shown in these drawings, the bodily fluid absorbent article 1 includes a liquid retaining material 2 for absorbing bodily fluids such as blood and tissue fluid, and a sheet material for fixing the contacting material 2 in contact with the skin. 3 and used by being attached to the skin. The body fluid absorbent article 1 is used for the purpose of absorbing body fluid leaking from the body to prevent soiling of clothing including underwear, as well as protecting and treating the affected area. The body fluid absorbent article 1 can be attached to various parts of the body where body fluid can leak, and the attachment part is not particularly limited, but is suitable for treatment of hemorrhoids, and should be used by sticking to the buttocks, particularly the vicinity of the anus. Can do.

  The sheet material 3 includes a sheet main body 30 and an adhesive layer 31 formed on the sheet main body 30. The adhesive layer 31 is affixed to the skin and plays a role of fixing the body fluid absorbent article 1 to the skin. The addressing material 2 is disposed on the surface 3 a on the skin side of the sheet material 3, that is, on the surface of the adhesive layer 31. In addition, the contact material 2 covers only a part of the surface 3a of the sheet material 3, more specifically, only the central portion in the longitudinal direction so that the adhesive layer 31 can be attached to the skin. As described above, the surface 2a on the skin side of the contact material 2 comes into contact with the skin in a state where the adhesive layer 31 of the sheet material 3 is attached to the skin.

  As shown in FIG. 1, the adhesive layer 31 is protected by the release paper 4 attached to the adhesive layer 31 before the body fluid absorbent article 1 is used. And when using the bodily fluid absorption article 1, this release paper 4 is removed (refer FIG. 2), and the adhesion layer 31 is affixed on skin so that the surface 2a of the contact material 2 may contact an affected part. In the use state of the body fluid absorbent article 1, that is, the state where it is attached to the skin, the upper side in FIG. 3 corresponds to the skin side, and the lower side corresponds to the opposite outer surface side. Hereinafter, “upper” and “lower” are defined based on the state of FIG. 3 unless otherwise specified.

  The bodily fluid absorbent article 1 according to the present embodiment provides a moist feeling without stickiness when used when a drug containing an oily component (hereinafter referred to as an oily drug) 5 is applied to the skin. Various devices for preventing leakage are applied to the material 2. In addition, the body fluid absorbent article 1 according to the present embodiment is also devised on the sheet material 3 so that leakage of body fluid can be prevented even when an oily medicine is used. Hereinafter, after describing the oil-based chemical here, the contact material 2 and the sheet material 3 will be described in detail.

<2. Detailed configuration of each part>
<2-1. Oily drug>
As a kind of oily medicine 5, arbitrary kinds, such as an ointment, a cream, a liquid agent, and a gel agent, can be chosen. The oily drug 5 is a drug containing an oily component. The content of the oil component in the entire oily drug 5 is not particularly limited, but is preferably 1% by weight or more, more preferably 10% by weight or more, and further preferably 20% by weight or more. Particularly preferred is ˜100% by weight. The oil-based medicine 5 typically refers to a base in which medicinal ingredients having physiological activity with respect to a living body are dispersed, but does not contain medicinal ingredients and consists only of the base. Cases are also included. Preferable examples when the base is an oily component include components such as wax, liquid oil, polyhydric alcohol and the like, or an emulsion obtained by emulsifying these components. Examples of waxes include white petrolatum, gelled hydrocarbons, microcrystalline wax, paraffin wax, cetanol, cetostearyl alcohol, stearyl alcohol, behenyl alcohol, honey beeswax, lanolin alcohol, etc. Paraffin, trait liquid paraffin, synthetic squalane, isopropyl myristate, dimethylpolysiloxane and the like can be mentioned. Examples of polyhydric alcohols include concentrated glycerin, 1,3-butylene glycol, propylene glycol and dipropylene glycol.

<2-2. Addressing material>
Next, the addressing material 2 will be described. The addressing material 2 has a laminated structure, and includes a hydrophilic layer 21 made of a hydrophilic material, and a lipophilic layer 22 formed on the upper surface of the hydrophilic layer 21 and made of a lipophilic material. As a material constituting the lipophilic layer 22, a material exhibiting hydrophobicity is typically selected from materials exhibiting lipophilicity. Moreover, the hydrophilic layer 21 is a layer which shows water absorption, and the lipophilic layer 22 is a layer which shows oil absorption. In addition, lipophilic here means the characteristic which shows affinity with the oil-based component contained in the oil-based chemical | medical agent 5. FIG.

  The upper surface of the lipophilic layer 22 corresponds to the uppermost surface (surface on the skin side) 2a of the coating material 2 and constitutes a contact surface with the skin. The lower surface of the hydrophilic layer 21 corresponds to the lowermost surface (surface opposite to the skin) 2b of the coating material 2 and constitutes a bonding surface with the adhesive layer 31 of the sheet material 3. Although the addressing material 2 according to the present embodiment is rectangular in plan view, it can of course have any shape such as a circle, an ellipse, or a polygon.

  The lipophilic layer 22 is liquid permeable and has a structure in which a fine space is formed inside. In the present embodiment, the lipophilic layer 22 is made of a nonwoven fabric. However, without being limited to this example, the lipophilic layer 22 may be a structure composed of other lipophilic fibers such as woven fabric and paper. However, from the viewpoint of improving the cushioning property and touch of the addressing material 2, the lipophilic layer 22 is preferably made of a nonwoven fabric. Preferable examples of the material of the lipophilic layer 22 include fibers such as polypropylene, polyethylene, polyethylene terephthalate, polyester, and polyamide. The lipophilic layer 22 may be formed by applying a lipophilic treatment (including a part of the water repellent treatment) to a layer made of a non-lipophilic material.

  The thickness of the lipophilic layer 22 is preferably 0.1 mm or more, and more preferably 0.3 mm or more. Moreover, the thickness of the lipophilic layer 22 is preferably 3 mm or less, and more preferably 1.5 mm or less.

  The hydrophilic layer 21 mainly serves to retain body fluid, and is disposed on the opposite side of the contact surface 2a with the skin with respect to the lipophilic layer 22. In the present embodiment, the hydrophilic layer 21 is configured as a laminate in which a plurality of layers 21a and 21a are bonded together. Thereby, the cushioning property of the hydrophilic layer 21 and by extension, the contact material 2 increases, the skin surface on which the body fluid absorbent article 1 is attached can be protected, and the touch can be improved. Furthermore, the amount of body fluid that can be retained by the hydrophilic layer 21 can be increased.

  The hydrophilic layer 21 is also liquid permeable and has a structure in which a fine space is formed inside, and is made of a nonwoven fabric in this embodiment. However, the present invention is not limited to this example, and the hydrophilic layer 21 may be a structure formed of other hydrophilic fibers such as woven fabric or paper. However, from the viewpoint of improving the cushioning properties and the touch of the coating material 2, the hydrophilic layer 21 is preferably made of a nonwoven fabric. Preferable examples of the material of the hydrophilic layer 21 include fibers such as cellulose fibers such as pulp, rayon and acetate. The hydrophilic layer 21 may be formed by subjecting a layer made of a non-hydrophilic material to a hydrophilic treatment.

  By having the above structure, the addressing material 2 can prevent the leakage of bodily fluids, and can improve the feeling of use of the oil-based medicine 5. That is, consider a scene where the bodily fluid absorbent article 1 is applied to the skin after the oily drug 5 is applied to the surface 2a of the contact material 2 or the skin surface (see FIG. 4A). At this time, the oil-based medicine 5 is pressed by the finger against the surface 2a of the addressing material 2 or compressed between the surface 2a of the addressing material 2 and the skin. However, since the surface 2a of the addressing material 2 is formed of the lipophilic layer 22, the oily chemical 5 can easily enter the gaps inside the lipophilic layer 22 (see FIG. 4B), and a large amount of oil The drug 5 does not stay on the surface 2 a of the contact material 2. On the other hand, since the lower layer of the lipophilic layer 22 is the hydrophilic layer 21, the oily drug 5 that has entered the lipophilic layer 22 hardly travels to the hydrophilic layer 21. The oily drug 5 can be retained moderately. As a result, the oily drug 5 can be appropriately supplied to the skin, and it is not sticky and a moist feeling is achieved.

  Moreover, if the oil-based medicine 5 does not enter the inside of the contact material 2 from the surface 2a, the oil-based medicine 5 spreads over the entire surface 2a. When the layer of the oil-based drug 5 is formed on the entire surface 2a, the layer blocks the body fluid path, and the body fluid cannot pass through the portion. However, in this embodiment, since the oil-based drug 5 quickly enters the lipophilic layer 22 that forms the surface layer of the addressing material 2, the layer of the oil-based drug 5 spreads over the surface 2a of the addressing material 2 over a wide range. There is nothing. As a result, the body fluid passes through the lipophilic layer 22 by capillary action through a portion where the layer of the oily drug 5 is not formed on the surface 2a. Thereafter, the body fluid is drawn into the lower hydrophilic layer 21 and held there (see FIG. 4C). Thereby, the side leak of a bodily fluid can be prevented. Moreover, since the bodily fluid once held in the hydrophilic layer 21 is blocked by the lipophilic layer 22, the return of the bodily fluid to the surface 2a is suppressed (see FIG. 4D).

  As described above, the excess oily drug 5 is absorbed by the lipophilic layer 22, and the body fluid is absorbed by the hydrophilic layer 21. Thereby, it is suppressed that the oil-based chemical | medical agent 5 and a bodily fluid enter between skin and the adhesion layer 31, and peeling from the skin of the bodily fluid absorption article 1 is also prevented.

The thickness of the addressing material 2 is preferably 3 mm or more, and more preferably 5 mm or more. Further, the thickness of the addressing material 2 is preferably 30 mm or less, more preferably 20 mm or less, and further preferably 18 mm or less. Also, an index representing the compressed ease or softness of the addressed material 2, WC value (the compression energy value) is preferably at 20gfcm / cm ² or more, more preferably 25gfcm / cm ² or more More preferably, it is 30 gfcm / cm ² or more. Further, WC value of compression wood 2 is preferably 100gfcm / cm ² or less, and more preferably 80gfcm / cm ² or less. Cushioning property and touch can be improved by setting the thickness and WC value of the contact material 2 in such a numerical range.

  In general, when the surface 2 a of the contact material 2 is formed of the lipophilic layer 22, it can be said that the body fluid is less likely to be absorbed by the hydrophilic layer 21 as compared to the case where there is no such lipophilic layer 22. . However, when the body fluid absorbent article 1 is attached to the skin, the contact material 2 is twisted to some extent, and wrinkles are formed in the lipophilic layer 22 disposed on the surface 2 a of the contact material 2. This wrinkle can cause an embossing effect on the surface 2a of the addressing material 2 and reduce the surface tension of the body fluid adhering to the surface 2a of the addressing material 2. As a result, the body fluid can easily enter the lipophilic layer 22 and can quickly move to the hydrophilic layer 21 via the lipophilic layer 22. Moreover, the wrinkles of the addressing material 2 increase with use. As a result, the embossing effect increases with use, and the absorbability of the body fluid of the addressing material 2 increases. Therefore, the decrease in absorbability with use is suppressed. In order to achieve the same effect, the upper surface of the lipophilic layer 22 may be embossed in advance to form irregularities. Moreover, the numerical range of the WC value of the addressing material 2 described above makes it easy to form appropriate wrinkles on the addressing material 2 and can be said to be preferable from this viewpoint.

<2-3. Sheet material>
Next, the sheet material 3 will be described. Although the shape of the sheet material 3 is not particularly limited, in the present embodiment, the sheet material 3 has a generally elongated rectangular shape in plan view, and more precisely, has a shape in which the long side of the rectangle is curved inwardly in an arc shape. . The above-described addressing material 2 is disposed in the center portion of the sheet material 3 in the longitudinal direction, and is along the long side forming the outline of the sheet material 3 in plan view.

  FIG. 5 is a partially enlarged side view of the sheet material 3. As described above, the sheet material 3 includes the sheet main body 30 and the adhesive layer 31 formed on the sheet main body 30, and the adhesive layer 31 serves as an adhesion surface to the skin. Further, the adhesive layer 31 firmly bonds the above-described coating material 2 and the sheet material 3.

  The sheet body 30 is made of a hydrophobic material. Preferably, the sheet body 30 is made of polypropylene, polyethylene, polyethylene terephthalate, polyester, polyamide, or the like. Further, the sheet main body 30 is liquid permeable and has a structure in which a fine space is formed inside. In the present embodiment, the sheet main body 30 is made of a nonwoven fabric. However, the present invention is not limited to this example, and the sheet main body 30 may be a structure made of other hydrophobic fibers such as woven fabric or paper. The sheet body 30 can also be a liquid impermeable sheet. However, from the viewpoint of securing the texture, it is preferable to select a nonwoven fabric as the material of the sheet body 30. The sheet body 30 may be formed by subjecting a non-hydrophobic material to a water repellent treatment.

  As described above, the adhesive layer 31 is formed on the surface of the sheet body 30 on the skin side and is attached to the skin, thereby fixing the body fluid-absorbing article 1 to the skin. The adhesive layer 31 constitutes a surface layer of the sheet material 3, and the adhesive layer 31 is formed with a groove pattern including a large number of grooves. In this embodiment, this groove pattern is formed over the entire surface 3a of the sheet material 3 as shown in FIGS. Preferably, this groove pattern is formed simultaneously with the application of the adhesive constituting the adhesive layer 31 to the surface of the sheet body 30.

  FIG. 6 is a partially enlarged plan view of the sheet material 3. In the present embodiment, the groove pattern is composed of a large number of first grooves 41 extending substantially parallel to each other and a large number of second grooves 42 intersecting the first grooves 41 and extending parallel to each other. The first groove 41 extends substantially parallel to the short direction of the sheet material 3, and the second groove 42 extends substantially parallel to the direction orthogonal to the first groove 41, that is, the longitudinal direction of the sheet material 3. Yes. By such a groove pattern, the body fluid that is not absorbed by the addressing material 2 and leaks onto the surface 3a of the sheet material 3 is captured by the grooves 41 and 42 on the surface 3a of the sheet material 3 and is held there. . Further, since the sheet main body 30 is made of a hydrophobic material and the adhesive layer 31 is present, the body fluid leaked onto the surface 3 a of the sheet material 3 does not immediately enter the gap of the sheet main body 30. Therefore, the body fluid moves on the sheet material 3 while being held in the grooves 41 and 42 by capillary action before leaching out. As a result, the body fluid is dispersed on the sheet material 3, and the body fluid can be held by the grooves 41 and 42 provided in the entire sheet 3. Thereby, leakage of body fluid to the outside can be prevented.

  Moreover, as shown in FIG. 6, the 1st groove | channel 41 which concerns on this embodiment is extended linearly continuously from the end to the end of the sheet | seat material 3 along a transversal direction. Thereby, the sheet | seat material 3 is easy to bend in a longitudinal direction, As a result, it can adhere more closely to the skin surface. On the other hand, the second groove 42 according to the present embodiment does not extend linearly continuously from end to end of the sheet material 3 along the longitudinal direction, but extends linearly while being interrupted in the longitudinal direction. On the other hand, the second groove 42 is connected to the first groove 41. As a result, the body fluid proceeds along the first groove 41 and bends at the second groove 42 while zigzag on the surface 3a of the sheet material 3, and more widely on the surface 3a of the sheet material 3. Can spread.

  As the pressure-sensitive adhesive constituting the pressure-sensitive adhesive layer 31, various materials such as rubber-based, acrylic-based, urethane-based, and silicon-based materials can be selected. In addition, as described above, the adhesive layer 31 is made of a hydrophobic adhesive so that the body fluid is more reliably dispersed along the groove pattern before the body fluid soaks into the sheet body 30 by capillary action. Can do. At this time, you may make it coat the whole surface of the sheet | seat main body 30 with an adhesive.

  The sheet material 3 has liquid permeability from the skin-side surface 3 a to the lower surface 3 b, and the lower surface 3 b of the sheet material 3 constitutes the outermost surface on the opposite side to the skin side in the body fluid absorbent article 1. That is, the body fluid absorbent article 1 according to the present embodiment is not provided with a leak-proof layer that is liquid impermeable and that blocks body fluid. Thereby, the outermost surface of the bodily fluid absorbent article 1 can be comprised by the sheet material 3 which consists of a nonwoven fabric, and the texture of the bodily fluid absorbent article 1 can be maintained. On the other hand, leakage of body fluid can be prevented by the body fluid holding function of the sheet material 3 described above.

<3. Packaged products>
FIG. 7 shows a package product 100 in which the body fluid absorbent article 1 and the oil-based drug 5 are accommodated in the same container 101. The container 101 can be in any form such as a box or a bag. The oily medicine 5 is filled in an arbitrary container 102 such as a tube or a jar. One container 101 can also contain a plurality of body fluid absorbent articles 1.

Further, the leak-proof layer 6 can be provided so as to cover the entire outermost surface of the sheet material 3, or can be provided only at a lower portion of the coating material 2 on the outermost surface of the sheet material 3. Preferable examples of the material of the leak-proof layer 6 include polypropylene, polyethylene, polyethylene terephthalate, polyester, polyamide and the like.

In the above embodiment, the groove pattern is formed in the adhesive layer 31. However, the groove pattern is not limited to this example. For example, in addition to the adhesive layer 31, the groove pattern is also formed in the sheet main body 30. (See FIG. 9A). Alternatively, the groove pattern can be formed only on the sheet main body 30, and the adhesive layer 31 can be formed at a location where the groove pattern is not formed (see FIG. 9B).
