Description

  The present invention relates to an auxiliary tool for patch application used when applying a patch to a desired site.

  Conventionally, various patches for the purpose of improving stiff shoulders, low back pain, muscle pain, muscle fatigue, joint pain and the like have been distributed. These patches are usually composed of a support, a pressure-sensitive adhesive layer containing a medicinal component, provided on one side of the support, and a release sheet that is releasably attached to the surface of the pressure-sensitive adhesive layer. It is configured. At the time of use, the release sheet is peeled off from the pressure-sensitive adhesive layer to expose the pressure-sensitive adhesive layer, and is applied to the application site.

  However, the patch after removing the release sheet is generally flexible and difficult to handle, and has a problem that it tends to wrinkle.

  Therefore, conventionally, for example, an auxiliary tool for patch application as described in Patent Document 1 below has been proposed. The instrument described in Patent Document 1 is provided on a support plate having a larger surface than the patch to be used, and on the outer edge portion of one surface of the support plate, and from the thickness of the patch to be used. And an annular spacer having a large thickness, and a temporary fixing means such as an adhesive layer that is fixed to one surface of the support plate and temporarily holds the patch to be used in a peelable manner. When using such an auxiliary device for patch application, first place the patch support on the temporary fixing means to temporarily fix the patch, and then slide the spacer over the skin to place the device on the desired application site. Place. And a patch is affixed on a desired site | part by pushing a support plate.

  According to this auxiliary tool for patch application, the patch can be held on the temporary fixing means fixed to the support plate in a state of being spread beautifully without wrinkles, and the patch can be bent during the application work. This can also prevent a problem that the adhesive surfaces of the patch are partially bonded to each other. Further, the user of the patch can accurately determine the application position of the patch to be used by the touch obtained by bringing the spacer in contact with the skin near the application site at the application site. Can be pasted in a clean state without any.

JP 2001-61894 A

  However, since the conventional auxiliary device for applying a patch as disclosed in Patent Document 1 has a temporary fixing means such as an adhesive layer, the auxiliary device is applied after applying the adhesive to the application site. When pulled away from the site, the patch may not be separated from the auxiliary device and may peel off from the site of application.

  The object of the present invention is to eliminate such problems.

  As a result of various studies by the inventors of the present invention to achieve the above object, as long as the spacer is around the patch even if there is no temporary fixing means, the patch is held inside the spacer and dropped from the auxiliary device. I found it difficult to do. For example, even when the patch is downward as shown in FIG. 4A, as long as the auxiliary device is moved in the direction of the hollow arrow, the patch is held inside the spacer by the air pressure and dropped. I found it not.

Therefore, the patch sticking auxiliary device according to the present invention is provided on the support plate having a larger surface than the patch to be used and the outer edge portion of one surface of the support plate, and the patch to be used. And a spacer that is easily elastically deformed when pressure is applied, and the portion of the support plate surrounded by the spacer is used as a mounting surface on which the patch is placed. The mounting surface is characterized in that it does not adhere to the surface of the patch support to be placed on the side opposite to the adhesive layer . That is, if the person has ordinary knowledge, the temporary fixing means is considered to be essential, but the temporary fixing means is not essential, and this is unnecessary.

  Further, the auxiliary device for patch application according to the present invention is provided for the patch application provided on the other surface of the support plate (the other surface or the side surface between the one surface and the other surface). It is also characterized by providing an attaching means for attaching to an element other than the auxiliary device. As a result, it is possible to attach the patch application auxiliary device to the wall or the like, and it is possible to apply the patch alone to the back.

  In the auxiliary device for applying a patch according to the above configuration, since the temporary fixing means is not necessary, the problem that the adhesive remains on the auxiliary device for applying the patch without being applied to the skin is solved.

  Further, since there is no temporary fixing means, durability due to repeated use is improved, manufacturing is facilitated, and manufacturing costs are reduced.

  Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals.

  FIG. 1 is a perspective view showing the basic configuration of a preferred embodiment of the auxiliary device for patch application of the present invention, FIG. 2 is a perspective view showing the back side of the auxiliary device for patch application, and FIG. , (B) is a longitudinal sectional view.

  As shown in FIGS. 1 to 3, the patch application auxiliary device 10 of the present embodiment includes a rectangular support plate 12, and a rectangular annular spacer 14 provided on an outer edge portion of one surface of the support plate 12. It has.

  The surface 16 of the support plate 12 surrounded by the spacer 14 serves as a patch mounting surface on which the patch 18 is mounted. Hereinafter, this surface 16 is referred to as a “patch mounting surface 16”. . The patch mounting surface 16 is similar to the patch 18 so that the patch 18 is mounted, and is slightly larger than the patch. Since the shape of the patch 18 that is normally used is rectangular, the shape of the patch placement surface 16 is also generally rectangular.

  Further, since the size of the support plate 12 is larger than the patch mounting surface 16 by at least the spacer 14, it is naturally larger than the size of the patch 18 used.

  Further, the constituent material of the support plate 12 is not particularly limited, but since the skin is pressed against the patch 18 placed on the patch placement surface 16, a certain degree of softness may be required. In order to prepare for handling, a certain degree of hardness may be required. Therefore, the material of the support plate 12 is preferably hard urethane, polyvinyl chloride (polyvinyl chloride), or the like. As other materials, for example, rubber (elastomer), rubber sponge, synthetic resin (excluding elastomer), synthetic resin sponge, paper, plastic, metal, etc. can be used and combined in layers. You can also.

  Since the patch mounting surface 16 is rectangular, the support plate 12 is preferably a rectangular flat plate similar to this, but is not limited thereto. For example, the shape of the support plate 12 can be a rectangle (including a square), a circle, an oval, an ellipse, a trapezoid, a rhombus, a parallelogram, a polygon, and other various shapes. Further, the support plate 12 has a surface having the patch mounting surface 16, a back surface on the opposite side, and a thickness for securing a desired hardness, that is, a side surface having a certain width. About the shape of the surface which has the patch mounting surface 16 at least, you may determine a shape according to the shape of the site | part to apply. For example, for a waist or a shoulder, it is preferable to have a curved shape according to the part. On the other hand, as will be described later, the back surface is preferably a flat surface in order to adhere to a wall or the like.

  In addition, although the surface which has the patch mounting surface 16 may be a smooth surface, you may attach an unevenness | corrugation with a cloth, a stripe, a check, a spot (polka dot pattern), for example. As a method for forming the unevenness, fine unevenness can be applied by printing as well as by normal molding.

  The spacer 14 is preferably a rectangular continuous annular body as shown in the figure because of the general shape of the patch 18. The spacer 14 is bonded to the outer edge portion of the support plate 12.

  In the illustrated embodiment, the spacer 14 includes an easily elastically deformable portion 20 that is bonded to the support plate 12 and a skin portion 22 that is bonded thereon.

  The material of the elastically deformable portion 20 is not particularly limited as long as it is more flexible than the support plate 12 and can be easily compressed when the spacer 14 is pressed against the support plate 12. A synthetic resin sponge is preferred. In addition, rubber (elastomer), rubber sponge, synthetic resin (excluding elastomer), and the like can also be used. The support plate 12 may be a foam made of a synthetic resin or rubber, and the material of the foam is not particularly limited. For example, natural rubber, synthetic rubber, polyurethane, polyolefin, polyester, polystyrene, Polyvinyl chloride, phenol resin, urea resin, epoxy resin, and the like are used, and these may be used alone or in combination of two or more. Among these materials, natural rubber, synthetic rubber, polyurethane, polyolefin, polyester, polystyrene, and polyvinyl chloride are preferable, and natural or synthetic rubber, polyurethane, polyethylene, polypropylene, and polyvinyl chloride are more preferable. As the resin foam, for example, commercially available products such as urethane, polystyrene foam, and cross-linked polyethylene foam (Softlon, manufactured by Sekisui Chemical Co., Ltd.) can be used. Alternatively, the foam made of the above synthetic resin or rubber and rubber, synthetic resin, paper, plastic, metal, or the like may be laminated.

  On the other hand, when the spacer 14 is brought into contact with the skin 30 of the human body, the epidermis portion 22 can easily slide the patch application auxiliary device 10 on the skin 30, and is pressed against the skin 30. For example, synthetic leather or the like is preferable. The skin portion 22 may be a cloth such as a woven fabric or a non-woven fabric, a film, or the like. Specifically, the cloth is a synthetic fiber or natural fiber such as polyurethane, polyester, polypropylene, polyvinyl acetate, polyvinylidene chloride, polyethylene, polyethylene terephthalate, nylon, acrylic, cotton, rayon, acetate, or a composite of these fibers. Examples thereof include a woven fabric or a non-woven fabric, and a composite material of these and a film having water vapor permeability. Examples of the film material include synthetic resins (excluding elastomers) and rubbers (elastomers). Specifically, soft polyvinyl chloride (soft PVC), polyurethane, low-density polyethylene, styrene-based elastomer, polyolefin-based elastomer And soft polyurethane-polyvinyl chloride graft polymer (PU-PVC). Of these, styrene-based elastomers and polyolefin-based elastomers are preferable because they have good stretchability. A soft film composed of at least one of a polyolefin-based elastomer and a styrene-based elastomer has a characteristic of good stretchability. The surface may be smooth, or may be uneven by a texture, stripe, check, spot (polka dot pattern). As a method for forming the unevenness, there is a printing method in addition to blasting or normal molding.

  Here, the thickness of the adhesive tape 24 is preferably in the range of 0.01 to 1 mm. If it is this range, in order not to impair the softness of the support plate 12, it can be made to adhere also to an uneven surface.

  Although the thickness of the spacer 14 is appropriately determined, when the patch application auxiliary device 10 is pressed against the skin 30, as shown in FIG. 3B, the thickness is equal to or slightly larger than the thickness of the patch 18. Although deformed to the extent, in a no-load state where no force is applied, as shown in FIG. At least in a no-load state, the patch 18 has a thickness such that the patch 18 on the patch placement surface 16 does not fall off even when the patch application auxiliary device 10 is substantially vertical as shown in FIG. It is effective.

  On the back surface of the support plate 12, an attaching means for attaching the patch application auxiliary device 10 to a wall or the like is provided. It is preferable that the attaching means can be repeatedly attached and detached. For example, as shown in FIG. 2, when the removable adhesive tape 24 is disposed along both short sides of the back surface of the support plate 12. Good. Further, when it is necessary to keep the patch application auxiliary device 10 attached to a wall or the like for a long time, a normal double-sided tape may be adhered to the back surface of the support plate 12. Furthermore, when sticking the patch sticking auxiliary instrument 10 to an iron surface such as a refrigerator, a magnet may be disposed on the back surface of the support plate 12.

  Next, a method of using the patch sticking auxiliary instrument 10 having the above-described configuration will be described.

  First, as shown by the two-dot chain line in FIG. 1, the patch 18 from which the release sheet has been removed is set so as to be neatly spread without wrinkles at the center of the patch mounting surface 16 of the patch application auxiliary device 10. And placed in a substantially non-adhered state. By doing in this way, the malfunction that the adhesive surfaces will adhere | attach partially because the patch 18 bends during a sticking operation | work can be prevented.

  Next, the patch 18 is held so that the patch 18 is exposed upward. From this substantially horizontal state to the substantially vertical state shown in FIG. 3B, it has been confirmed by experiments that the patch 18 does not fall and is held on the patch placement surface 16. . This is considered to be because the effect of maintaining the shape of the patch 18 itself and the effect of adhesion appearing when the edge of the adhesive layer of the patch partially contacts the spacer 14.

  Then, the spacer 14 of the patch application auxiliary device 10 is pressed against the skin 30 of the human body. At this time, if it is not a desired part, the position adjustment is performed by sliding the patch application auxiliary device 10 on the skin 30. Thereafter, when the auxiliary device 10 for applying the patch is pressed, the support plate 12 is harder than the elastically deformable portion 20 of the spacer 14, so that the spacer 14 is compressed, and as shown in FIG. 30 contacts the patch 18 on the patch mounting surface 16.

  Thereafter, when the patch application auxiliary device 10 is pulled away from the skin, the patch 18 is merely placed on the patch placement surface 16, and therefore the patch 18 is stuck to the skin. . During this time, since the patch 18 maintains a wrinkle-free state, the affixed state is also clean without wrinkles.

  Next, when the patch 18 is applied to the upward skin 30 such as the shoulder, the patch placement surface 16 of the patch application auxiliary device 10 is necessarily downward. In this case, the patch 18 may fall from the patch mounting surface 16, but while the auxiliary tool 10 for patch application is being moved, as indicated by the hollow arrow in FIG. Since the patch 18 is lightweight and flat, the patch 18 is held on the patch mounting surface 16 by wind pressure. Therefore, as shown in FIG. 4B, the patch 18 can be suitably applied to the upward skin 30 such as the shoulder.

  Further, by using the adhesive tape 24 which is an attaching means on the back surface of the patch application auxiliary device 10, the patch application auxiliary device 10 can be attached to a vertical surface 40 such as a wall or a column. FIG. 5 shows this adhesion state, and as can be easily understood from this figure, the patch 18 can be applied to the back of the human body without the help of others. Of course, as described above, the patch 18 does not fall off even if the patch application auxiliary device 10 is substantially vertical as shown in FIG.

  The adhesive means such as the adhesive tape 24 not only attaches the patch application auxiliary device 10 to a vertical surface such as a wall or a column, but also attaches a stick, handle, belt, etc. to the patch application auxiliary device 10. It is also possible to operate the auxiliary tool 10 for sticking a patch with the stick, handle, belt and the like.

  Although the patch application auxiliary device 10 is used as described above, in relation to this method of use, the dimensions, elasticity, flexibility, etc. of each component of the patch application auxiliary device 10 are further detailed. To consider.

  First, in the no-load state, the thickness T1 of the spacer 14 is preferably within a predetermined range, mainly for the purpose of suitably accommodating the patch 18 inside the spacer 14. That is, if T1 is too small, the patch 18 may protrude from the spacer 14 when the patch 18 is applied. Therefore, it is preferable to set a lower limit of T1. On the other hand, when T1 is too large, when the patch 18 is pressed against the body and the patch 18 is applied, the deformation of the spacer 14 increases, and the adhesive layer of the patch 18 becomes the spacer 14. There is a possibility that it may easily interfere with the side surface of the patch mounting surface 16 side. For this reason, it is preferable to also determine the upper limit of T1. Specifically, T1 is preferably in the range of 1 to 10 mm, for example. For the same reason as described above, if T1 is determined from the relationship of the thickness T2 of the patch 18, T1 is preferably in the range of 1.5 to 20 times T2.

  Regarding the elastic resistance (strength of strength) or flexibility of the spacer 14, it is important to have the elastic resistance or flexibility close to the applied body part in order to apply the patch 18 without error. For this reason, when forming the easily elastic deformation part 20 from a foam, it is necessary to determine a foaming rate suitably. That is, when the foaming rate is too small, the elastic resistance of the spacer 14 is too strong and the flexibility becomes poor, so that it is difficult to apply to uneven body surfaces. On the other hand, when the expansion ratio is too large, there is a problem that the physical strength necessary for the spacer 14 is insufficient. Therefore, the foaming rate is preferably in the range of 3 to 50 times, for example.

  The same can be said for the skin portion 22 constituting the spacer 14, and when the thickness T3 of the skin portion 22 is too small, the physical strength of the skin portion 22 may be insufficient. It becomes difficult to apply to a certain body surface. Therefore, T3 is preferably in the range of 0.2 to 2.5 mm, for example.

  When the dimensions of the patch 18 are longitudinal (longitudinal direction) L1 cm and lateral (short direction) L2 cm, the longitudinal dimensions of the patch placement surface 16 are (L1 + 0.4) cm to (L1 + 1. 5) The range of cm and the width are preferably in the range of (L2 + 0.3) cm to (L2 + 1.0) cm. Within this size range, it is possible to prevent the adhesive layer of the patch 18 from coming into contact with the spacer 14 when the patch 18 is placed on the patch placement surface 16, and the patch placement surface 16. Since the play of the patch 18 on the upper side is small, it is possible to prevent the patch 18 from being applied to a desired site, and thus it is possible to reliably prevent the patch 18 from being wrinkled. Therefore, in the case of the patch 18 having a length of 6.5 cm and a width of 4.2 cm, the dimensions of the patch mounting surface 16 are preferably 6.9 to 8 cm and 4.5 to 5.2 cm. In the case of the patch 18 having a length of 10 cm and a width of 7 cm, the dimensions of the patch mounting surface 16 are preferably 10.4 to 11.5 cm and 7.3 to 8.0 cm. In the case of a patch 18 having a length of 14 cm and a width of 10 cm, the dimensions of the patch mounting surface 16 are preferably 14.4 to 15.5 cm and 10.3 to 11 cm in width. Furthermore, in the case of the patch 18 having a length of 20 cm and a width of 14 cm, the dimensions of the patch mounting surface 16 are preferably 20.4 to 21.5 cm in length and 14.3 to 15 cm in width.

  Furthermore, when the support plate 12 is made of hard urethane, the thickness T4 is preferably in the range of 3 to 40 mm, for example. If it is this range, since the support plate 12 has appropriate hardness, it is easy to handle, and the patch 18 supported on the support plate 12 is excessively deformed together with the support plate 12 to cause wrinkles. It doesn't happen. Moreover, when the support plate 12 consists of polyvinyl chloride, it is preferable that the thickness T4 shall be in the range of 0.05-5 mm, for example. If it is this range, since the support plate 12 has appropriate hardness, it is easy to handle, and the patch 18 supported on the support plate 12 is excessively deformed together with the support plate 12 to cause wrinkles. In addition, since the support plate 12 has appropriate softness, it can be easily attached to the curved portion.

  As mentioned above, although preferred embodiment of this invention was described in detail, it cannot be overemphasized that this invention is not limited to the said embodiment. For example, in the above embodiment, the spacer 14 includes the easily elastically deformable portion 20 and the skin portion 22, but the skin portion 22 may be omitted.

  Moreover, in the said embodiment, although the spacer 14 is made into the continuous annular body, as shown in FIG. 6, it is good also as a discontinuous form.

  Furthermore, in the above embodiment, the attaching means is provided on the back surface of the support plate 12, but it may be provided on the side surface of the support plate 12.

  Furthermore, when the vertical dimension or the horizontal dimension of the inner edge (the patch mounting surface 16) of the spacer 14 is the same as or slightly smaller than the vertical dimension or the horizontal dimension of the patch 18 (about 0.1 mm), it is easy to use the spacer. The elastically deformable portion 20 comes into contact with the edge portion of the patch 18 and can be held. In this case, there is an effect that the patch 18 can be held in the auxiliary device 10 even when the dispensing sticking auxiliary device 10 is faced down, without a conventional temporary fixing means such as an adhesive layer.

  In general, the patch 18 has a longitudinal dimension L1 in the range of 3 to 25 cm and a lateral dimension L2 in the range of 2 to 20 cm. However, in the case of the maximum dimension, the patch 18 is held by hand. It is thought that it is not possible. Therefore, as shown in FIG. 7A, the intermediate portion of the support plate 12 is thinned, or as shown in FIG. 7B, at least one of the short side portion or the long side portion of the support plate 12 is used. The handle portion 26 may be formed by extending the length so that it can be easily held by hand. Of course, the handle portion 26 may be applied to the auxiliary device 10 for small patches.
