Description
Light irradiation pad support member, light irradiation pad set, and light therapy device 【0001】 The present invention relates to a light irradiation pad support member, a light irradiation pad set, and a phototherapy device. This application claims priority to Japanese Patent Application No. 2022-106357, filed on June 30, 2022, the contents of which are incorporated herein by reference. 【0002】 Conventionally, phototherapy devices for treating neonatal jaundice have been known that include a flat light-irradiation pad (see, for example, Patent Document 1). With this conventional phototherapy device, a baby is laid supine on the light-irradiation pad, and therapeutic light (hereinafter sometimes simply referred to as "light") is irradiated from the light-irradiation pad toward the baby, thereby enabling even irradiation of the baby's back and more effective jaundice treatment. Furthermore, because it is a so-called pad-type phototherapy device, it is possible to promote physical contact between mother and child, such as holding or breastfeeding the baby, while continuing jaundice treatment. 【0003】 Japanese Patent Application Publication No. 2013-248226 【0004】 However, in the field where pad-type phototherapy devices are used, there is a demand for preventing excessive curvature of the light-irradiation pad toward the non-irradiated side (the side of the light-irradiation pad opposite the surface that is irradiated with light) due to structural reasons of the light-irradiation pad. To meet this demand, for example, it is conceivable to increase the rigidity of the light-irradiation pad itself, but in that case, not only curvature toward the non-irradiated side but also curvature toward the irradiated side would be suppressed, making it difficult to maintain skin-to-skin contact between mother and child while continuing jaundice treatment. 【0005】 Therefore, the present invention has been made in consideration of the above circumstances, and aims to provide a light irradiation pad support member, a light irradiation pad set, and a light therapy device that can prevent the light irradiation pad from bending toward the non-irradiated side, while allowing skin-to-skin contact between mother and child while continuing jaundice treatment. 【0006】The light irradiation pad support member of the present invention is a support member that supports a light irradiation pad used in a light therapy device, and the support member is configured to be able to support the light irradiation pad when placed on the non-irradiated surface side that is opposite the irradiated surface of the light irradiation pad, and is configured to allow bending of the light irradiation pad toward the irradiated surface side while suppressing bending toward the non-irradiated surface side when supporting the light irradiation pad. 【0007】 According to the present invention, the light-irradiating pad support member of the present invention is configured to allow bending of the light-irradiating pad toward the irradiation surface side while suppressing bending toward the non-irradiating surface side when the light-irradiating pad is supported. Therefore, by using the light-irradiating pad support member of the present invention for the light-irradiating pad, it is possible to prevent bending of the light-irradiating pad toward the non-irradiating surface side while allowing a patient to hold or breastfeed a baby while continuing jaundice treatment. 【0008】 In the light irradiation pad support member of the present invention, preferably, the support member is formed in a plate shape, has a first surface with a notch of a predetermined depth and a second surface located opposite the first surface, and is configured to support the light irradiation pad with the first surface facing the non-irradiated surface side and the second surface facing the irradiated surface side. That is, the support member is a plate-like member, and the first surface of the plate-like member is provided with a notch of a predetermined depth, and is configured to support the light irradiation pad with the first surface facing the non-irradiated surface side and the second surface facing the irradiated surface side. This makes it possible to relatively easily realize the light irradiation pad support member of the present invention, which exhibits excellent effects. 【0009】 In the light irradiation pad support member of the present invention, preferably, the support member has a structure in which a plurality of plate pieces are arranged on the first surface side and a sheet-like base layer is arranged on the second surface side, and the plurality of plate pieces are arranged in a planar manner on the base layer, and the slits are formed by gaps between adjacent plate pieces. In this case, the light irradiation pad support member of the present invention can be manufactured relatively easily, for example, by bonding the plurality of plate pieces to the base layer using an adhesive, thereby reducing manufacturing costs. 【0010】In the light irradiation pad support member of the present invention, the support member preferably has a single-layer structure in which a gap corresponding to the notch is formed on one side of a plate material of a predetermined thickness. In this case, the light irradiation pad support member of the present invention can be manufactured relatively easily, for example, by slitting one side of the plate material, thereby reducing manufacturing costs. 【0011】 In the light irradiation pad support member of the present invention, preferably, the support member has a substantially rectangular shape in plan view, and the slits are formed along the long and short side directions of the support member and along a diagonal direction intersecting the long and short side directions. This allows the light irradiation pad support member to be bent more flexibly, and using it in a light irradiation pad can improve usability when holding or nursing a baby (ease of bending toward the irradiation surface). 【0012】 The light irradiation pad set of the present invention is a light irradiation pad set that combines a light irradiation pad used in a light therapy device with the light irradiation pad support member of the present invention described above, and therefore makes it possible to hold or breastfeed a baby while continuing jaundice treatment, while preventing the light irradiation pad from bending toward the non-irradiated side. 【0013】 The phototherapy device of the present invention is a phototherapy device that includes a light source, a light irradiation pad that irradiates light from the light source, a light guiding section that guides the light from the light source to the light irradiation pad, and the above-mentioned light irradiation pad support member of the present invention, so that it is possible to hold or breastfeed a baby while continuing jaundice treatment, while suppressing bending of the light irradiation pad toward the non-irradiated side. 【0014】 According to the present invention, it is possible to prevent the light irradiation pad from bending toward the non-irradiated surface side, while allowing a patient to hold or breastfeed a baby while continuing jaundice treatment. 【0015】1 is a plan view of a light-irradiating pad support member 1 according to a first embodiment of the present invention.

In the drawings, the lengths and thicknesses of some components are exaggerated to facilitate understanding of the invention. 【0017】 [Light irradiation pad support member according to the first embodiment] The light irradiation pad support member 1 according to the first embodiment (hereinafter sometimes simply referred to as "support member") is a plate-like member that is generally rectangular in plan view, as shown in Fig. 1. The top surface of the support member 1 (the surface shown in Fig. 1) is the first surface 1a, and the bottom surface of the support member 1 (the surface shown in Fig. 2) is the second surface 1b. A cutout portion 1c that is cut out in a generally rectangular shape in plan view is provided on the right side surface of the support member 1 (the right side in Figs. 1 to 3). 【0018】 As shown in Figures 4 and 5, the support member 1 has a laminated structure in which multiple plate pieces 10 are arranged in a planar manner on a sheet-like base material layer 20 located on the second surface 1b side, with an adhesive layer 30 interposed therebetween. 【0019】The plurality of plate pieces 10 are made of a plastic material such as polypropylene resin. By using a low-foaming material (e.g., a low-foaming plastic such as low-foaming polypropylene) as the plate pieces 10, it is possible to reduce the weight of the entire support member while maintaining the required strength. 【0020】 Each of the plurality of plate pieces 10 has a planar shape such as a triangle or a rectangle, as shown in Fig. 1. The thickness of each plate piece 10 is the same, and is set to, for example, 1 mm to 20 mm. 【0021】 The base layer 20 is made of, for example, a vinyl multi-layer sheet that is excellent in flexibility and durability, and has a thickness of, for example, 0.1 mm to 2 mm. 【0022】 The adhesive layer 30 is made of, for example, an acrylic double-sided adhesive tape or an adhesive sheet. The thickness of the adhesive layer 30 is set to, for example, 1 mm or less. 【0023】 1, 4, and 5, the first surface 1a of the support member 1 has slits 12 (12a, 12b, 12c) of a predetermined depth. The slits 12 are formed by the gaps between adjacent plate pieces 10, and the depth of the slits 12 is the same as the thickness of the plate pieces 10. Each plate piece 10 is adhered to the adhesive layer 30, but adjacent plate pieces 10 are not adhered to each other. 【0024】 1, the notches 12 are composed of notches 12a formed along the long side direction of the support member 1, notches 12b formed along the short side direction of the support member 1, and notches 12c formed along a diagonal direction intersecting the long side direction and the short side direction of the support member 1. The number of notches 12a is, for example, three, and the number of notches 12b is, for example, eight (excluding two notches 12b provided near the cutout portion 1c), and they are arranged at equal intervals from each other. 【0025】Since the planar shape of the support member 1 is approximately rectangular, the notches 12a and 12b are perpendicular to each other. The notch 12c is formed so as to intersect with the notches 12a and 12b at a 45-degree angle, and is made up of multiple notches, one extending diagonally from the upper right to the lower left in Fig. 1 (like a slash in a symbol character) and the other extending diagonally from the upper left to the lower right in Fig. 1 (like a backslash in a symbol character). 【0026】 Because the notches 12a to 12c are formed on the first surface 1a, the support member 1 can be bent toward the second surface 1b with a relatively high degree of freedom, as shown in Figures 7 to 9. On the other hand, because no notches are formed on the second surface 1b of the support member 1 (see Figure 2), it is difficult to bend the support member 1 toward the first surface 1a. In other words, because the notches 12a to 12c are formed on the first surface 1a, the support member 1 can be deformed so that the first surface 1a is convex and the second surface 1b is concave, but because no notches are formed on the second surface 1b of the support member 1, it is difficult to deform the support member 1 so that the first surface 1a is concave and the second surface 1b is convex. 【0027】 1 and 6, at the peripheral edge of the support member 1, the slit 12b formed along the short side direction of the support member 1 and the slit 12c extending diagonally do not intersect, and the end of the slit 12c is located at a predetermined distance from the end of the slit 12b. Similarly, at the peripheral edge of the left side surface of the support member 1, the slit 12a formed along the long side direction of the support member 1 and the slit 12c extending diagonally do not intersect, and the end of the slit 12c is located at a predetermined distance from the end of the slit 12a. 【0028】10 , the phototherapy device 100 according to the first embodiment includes a device main body 110 having a built-in light source (not shown) made of a blue LED, a light guide unit 120 configured to be connectable to the device main body 110, a light irradiation pad 130 connected to the light guide unit 120, and a support member 1 for supporting the light irradiation pad 130. The combination of the light irradiation pad 130 and the support member 1 constitutes a light irradiation pad set 150. 【0029】 The phototherapy device 100 is a device for performing phototherapy (also called phototherapy or phototherapy) on, for example, a newborn baby or other infant suffering from jaundice. In the phototherapy device 100 shown in Figure 10, the support member 1 is disposed inside the light irradiation pad 130. 【0030】 The light guide unit 120 has a structure in which, for example, multiple optical fibers are bundled into a rod shape, and has a function of guiding light from the light source to the light irradiation pad 130. A plug 122 is provided at one end of the light guide unit 120, and is configured to be attachable to and detachable from the connection socket 112 of the device main body 110. 【0031】 The light irradiation pad 130 is, for example, a flat member having a substantially rectangular shape in a plan view, and is connected to the other end of the light guide section 120. A plurality of optical fibers are arranged inside the light irradiation pad 130. The optical fibers are arranged such that the optical fibers, which were bundled in a rod shape, spread out radially from the light guide section 120 side to the opposite side and are further arranged in a plane (see FIG. 12 ). 【0032】 11 , the light irradiation pad 130 has an optical fiber layer 132, a reflective layer 134 disposed on the bottom side of the optical fiber layer 132 (the lower side in FIG. 11 ), a protective layer 136 disposed on the upper side of the optical fiber layer 132 (the upper side in FIG. 11 ), and a bag-shaped cover member 138. The three layers of the optical fiber layer 132, the reflective layer 134, and the protective layer 136 are laminated in a planar manner, and these three layers are covered from the outside by the bag-shaped cover member 138 (i.e., the optical fiber layer 132, the reflective layer 134, and the protective layer 136 are disposed inside the bag-shaped cover member 138). 【0033】The support member 1 is disposed between the reflective layer 134 and the cover member 138 (the lower cover member 138) inside the bag-shaped cover member 138. Although not illustrated, the support member 1 disposed inside the cover member 138 is disposed so that the cutout portion 1c of the support member 1 is positioned at the connection portion between the light guide unit 120 and the light irradiation pad 130 (i.e., so that the cutout portion 1c faces the light guide unit 120). 【0034】 11 and 12 , the optical fiber layer 132 is subjected to a treatment for emitting light toward the upper surface (irradiation surface S) of the optical fiber layer 132. An example of the treatment for emitting light is the treatment disclosed in Japanese Patent Application Laid-Open No. 2013-248226 (a treatment for breaking a part of the cladding layer of each optical fiber 132 a by means of laser cutting or the like to form a broken portion 132 b). 【0035】 The reflective layer 134 is, for example, a reflective sheet formed in a sheet shape, and is attached to the bottom surface side (non-irradiated surface NS side) of the optical fiber layer 132 using double-sided tape or the like. 【0036】 The protective layer 136 is a gel-like elastic body made of, for example, synthetic resin, and has the function of protecting the optical fiber layer 132 by being disposed on the upper surface side (the irradiation surface S side) of the optical fiber layer 132. By using, for example, urethane gel as the protective layer 136, high transparency and flexibility can be achieved. 【0037】 The cover member 138 is a member obtained by molding a sheet made of, for example, synthetic resin into a bag shape. By using, for example, a urethane sheet as the cover member 138, high transparency and flexibility can be achieved. 【0038】 By using the light irradiation pad 130 configured as above, light from the light source is irradiated toward the upper side in Fig. 11. At this time, the upper surface of the light irradiation pad 130 in Fig. 11 becomes the irradiation surface S, and the lower surface of the light irradiation pad 130 in Fig. 11 becomes the non-irradiation surface NS. The support member 1 built into the light irradiation pad 130 is arranged so that the second surface 1b without the notch 12 faces the reflective layer 134. 【0039】 When the light irradiation pad 130 is supported by the support member 1 of this embodiment and the baby B is placed on the irradiation surface S of the light irradiation pad 130, bending toward the irradiation surface S is permitted while bending toward the non-irradiation surface NS is suppressed, as shown in Figure 13. 【0040】 In other words, by using the support member 1 of this embodiment, it is possible to hold and breastfeed baby B while continuing jaundice treatment, while suppressing bending of the light irradiation pad 130 toward the non-irradiated surface NS. 【0041】 In this embodiment, the support member 1 is configured to be able to support the light irradiation pad 130 in a state in which the first surface 1a, which has the notches 12 of a predetermined depth, faces the non-irradiated surface NS, and the second surface 1b faces the irradiated surface S. This makes it possible to relatively easily realize a support member 1 that exhibits excellent effects. 【0042】 In this embodiment, the support member 1 has a laminated structure in which a plurality of plate pieces 10 are arranged in a planar manner on a sheet-like base material layer 20 located on the second surface 1b side, and the notches 12a to 12c are formed by gaps between adjacent plate pieces 10. This allows the support member 1 to be manufactured relatively easily, thereby reducing manufacturing costs. 【0043】 In this embodiment, the above-described notches 12a to 12c are formed in the support member 1, which allows the support member 1 to bend more flexibly. As a result, by using the support member 1 in the light irradiation pad 130, it is possible to improve the comfort of use (ease of bending when bending toward the irradiation surface S) and stability when holding or nursing the baby B. 【0044】6, in this embodiment, notches 12b and 12c do not intersect at the peripheral portion of support member 1, and the end of notch 12c is located a predetermined distance away from the end of notch 12b. In other words, when the plate pieces 10 located on both sides of notch 12b are viewed from above, the outline of each plate piece 10 is not a right-angled isosceles triangle, but rather has a shape in which one of the two acute angles constituting the right-angled isosceles triangle is missing, the corner located on the peripheral side of support member 1 (a triangle with a partially missing corner). According to experiments conducted by the inventor, a configuration in which the end of notch 12c is positioned at a predetermined distance from the end of notch 12b, as in this embodiment, can increase the bonding strength (resistance to peeling) between the plate piece 10 and the base layer 20 when the support member 1 is bent toward the second surface 1b, compared to when the end of notch 12b and the end of notch 12c are in the same position (when the outlines of each plate piece 10 on both sides of notch 12b are right-angled isosceles triangles). 【0045】 In this embodiment, the phototherapy device 100 is equipped with the support member 1 described above, and as shown in Figure 13, it is possible to hold or breastfeed a baby while continuing jaundice treatment, while suppressing bending of the light irradiation pad 130 toward the non-irradiated surface NS. 【0046】 [Supporting member according to the second embodiment] Fig. 14 is a diagram for explaining the structure of a light irradiation pad supporting member 2 (supporting member 2) according to the second embodiment, and corresponds to Fig. 4 in the first embodiment. Note that the same members as those described in the first embodiment are given the same reference numerals, and detailed description thereof will be omitted. 【0047】 The support member 2 according to the second embodiment differs from the support member 1 according to the first embodiment in that it has a single-layer structure (a plate material having a predetermined thickness) rather than a laminated structure. 【0048】 The plate material 40 is a flexible plate-like member made of, for example, a plastic material and having a rectangular shape in a plan view. The thickness of the plate material 40 is set to, for example, 1 mm to 20 mm. 【0049】14, a gap 42 is formed on the first surface 1a of the plate material 40. The depth of the gap 42 is set to, for example, 10% to 90% of the thickness of the plate material 40 (when the thickness of the plate material is 10 mm, the depth of the gap 42 is 1 mm to 9 mm). As a method for manufacturing the plate material 40 having the gap 42 formed therein, for example, a known method such as slit processing, laser processing, press molding, etc. can be used. 【0050】 The gaps 42 correspond to "notches of a predetermined depth" in the present invention, and similar to the notches 12 described in the first embodiment, a plurality of gaps 42 are formed along the long side direction, short side direction, and diagonal direction of the support member 2. The formation of the gaps 42 in the first surface 1a of the plate material 40 allows the support member 2 to bend toward the second surface 1b with a relatively high degree of freedom. On the other hand, the absence of the gaps 42 in the second surface 1b of the support member 2 makes it difficult to bend the support member 2 toward the first surface 1a. That is, the formation of the gaps 42 in the first surface 1a of the plate material 40 allows the support member 2 to be deformed so that the first surface 1a is convex and the second surface 1b is concave. However, the absence of the gaps 42 in the second surface 1b of the support member 2 makes it difficult to deform the support member 2 so that the first surface 1a is concave and the second surface 1b is convex. 【0051】 As described above, the support member 2 according to the second embodiment differs from the support member 1 according to the first embodiment in that it has a single-layer structure rather than a laminated structure, but like the support member 1 according to the first embodiment, when a baby is placed on the irradiation surface of the light irradiation pad while the light irradiation pad is supported by the support member 2, bending toward the irradiation surface is permitted while bending toward the non-irradiation surface is suppressed. In other words, by using the support member 2 according to the present embodiment, bending toward the non-irradiation surface of the light irradiation pad can be suppressed, while making it possible to hold or breastfeed the baby while continuing jaundice treatment. 【0052】 The support member 2 of the second embodiment has the same configuration as the support member 1 of the first embodiment, except that it has a single-layer structure rather than a laminated structure, and therefore has the same effects as the support member 1 of the first embodiment. 【0053】[Phototherapy Device According to Third Embodiment] Fig. 15 is an overall perspective view of a phototherapy device 300 according to a third embodiment. Note that the same components as those described in the first embodiment are given the same reference numerals, and detailed description thereof will be omitted. 【0054】 In the first embodiment, the support member 1 is built into the light irradiation pad 130 (see Figures 10 and 11), whereas in the third embodiment, the support member 1 is not built into the light irradiation pad 330, and the light irradiation pad 330 and the support member 1 are stored in the storage body 340. 【0055】 Although not illustrated, the light irradiation pad 330 of the third embodiment has an optical fiber layer, a reflective layer, a protective layer, and a cover member, similar to the light irradiation pad 130 of the first embodiment, but the support member 1 is not disposed inside the cover member. 【0056】 The housing 340 is a flat member, for example, roughly rectangular in plan view, similar to the light irradiation pad 330, and has a pocket-shaped storage section 342. The storage section 342 is sized to be able to store the light irradiation pad 330 and the support member 1. The housing 340 is made of a synthetic resin, for example, urethane, and with the light irradiation pad 330 and the support member 1 stored in the storage section 342, light can be irradiated towards the baby through the housing 340. 【0057】 In the phototherapy device 300 according to the third embodiment, similarly to the phototherapy device 100 according to the first embodiment, when a baby is placed on the irradiation surface of the light irradiation pad 330 (the upper surface of the storage section 342) with the light irradiation pad 330 supported by the support member 1, bending toward the irradiation surface (the upper surface side of the storage body 340) is permitted, while bending toward the non-irradiation surface (the bottom surface side of the storage body 340) is suppressed. In other words, in the case of the phototherapy device 300 according to the third embodiment, bending toward the non-irradiation surface is suppressed, while allowing the baby to be held or breast-fed while continuing jaundice treatment. 【0058】In this embodiment, the light irradiation pad 330 and the support member 1 are stored in the storage section 342 of the storage body 340, so that the support member 1 can be removed relatively easily from the storage body 340 (storage section 342). This is convenient when, for example, it is desired to replace only the support member 1. 【0059】 As described above, the light therapy device 300 of the third embodiment differs from the light therapy device 100 of the first embodiment in terms of the position of the support member 1 (whether or not the support member 1 is built into the light irradiation pad), but in other respects it has the same configuration as the light therapy device 100 of the first embodiment, and therefore retains the relevant effects of the light therapy device 100 of the first embodiment. 【0060】 The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, the following modifications are also possible. 【0061】 In the above embodiment, the case where the plurality of plate pieces constituting the support member are made of a plastic material such as polypropylene resin has been described as an example, but this is not limiting, and other materials such as metal may also be used as long as they satisfy the required conditions of strength, weight, etc. 【0062】 In the above embodiment, a vinyl multilayer sheet is used as the base layer constituting the support member, but this is not limiting. Sheets made of other materials may be used as long as they satisfy the requirements of flexibility, durability, etc. Note that by mixing fibers into a portion of the resin material, it is possible to suppress the in-plane extension of the base layer. 【0063】 In the above embodiment, an acrylic double-sided adhesive tape or adhesive sheet is used as the adhesive layer constituting the support member, but the present invention is not limited to this, and adhesive tapes made of other materials may also be used. Furthermore, other known joining means, such as applying an adhesive, may also be used as long as it is possible to attach multiple plate pieces to the base layer. 【0064】In the above embodiment, an example was given of using synthetic resin such as urethane as the material for the cover member and storage body that make up the light irradiation pad, but this is not limited to this, and other materials such as transparent silicone rubber may also be used. 【0065】 In the above embodiment, a case where a light source is disposed in the device body of the phototherapy device and light from the light source is emitted from the light irradiation pad through the optical fiber of the light guide portion is described as an example, but the present invention is not limited to this. For example, the present invention can also be applied to a light irradiation pad that has multiple LEDs built into it. 【0066】 In the above embodiment, the planar shapes of the light irradiation pad and the support member are both approximately rectangular, but this is not limited thereto and may be other shapes, such as a square. Also, the support member does not necessarily have to have a cutout portion. 【0067】 In the above embodiment, the case where the notches are formed along the long side direction, the short side direction, and the diagonal direction of the support member has been described as an example, but this is not limited to this. For example, the notches may be formed only along the long side direction and the short side direction of the support member, or only along the diagonal direction of the support member. If the planar shape of the support member is a shape other than a substantially rectangular shape, the direction of the notches can also be selected appropriately. Furthermore, the notches are not limited to being straight in a planar view, but may also be curved. 【0068】 In the above embodiment, the support member is described as being built into the light irradiation pad or stored in the storage section of the storage body, but this is not limiting. For example, the support member may be attached to the outer surface of the light irradiation pad using a hook-and-loop fastener or the like. Furthermore, if the support member is transparent and does not block the light emitted from the light irradiation pad, the support member can also be attached to the irradiation surface of the light irradiation pad. In this case, although there is a possibility that the baby's skin may come into direct contact with the support member, there is no slit formed on the contact surface of the support member (the surface with the slit faces the light irradiation pad), so there is no risk of the slit in the support member coming into direct contact with the baby. 【0069】 In the above embodiment, a phototherapy device for use on infants such as newborns has been described, but the present invention is not limited to this and can also be applied to phototherapy devices used on patients other than newborns, etc. Furthermore, the types of diseases for which the phototherapy device of the present invention can be used are not limited to neonatal jaundice. 【0070】 The material, shape, size, number, location, etc. of each component in the above embodiment are arbitrary and not limited as long as they can achieve the present invention. 【0071】 This makes it possible to hold or breastfeed a baby while continuing jaundice treatment, while also preventing the light-irradiating pad from bending toward the non-irradiated side. 【0072】 1, 2 Light irradiation pad support member (support member) 1a First surface (of support member) 1b Second surface (of support member) 10 Plate piece 12, 12a to 12c Slit 20 Base material layer 30 Adhesive layer 40 Plate material 42 Gap (slit) 100, 300 Light therapy device 110 Device body 120 Light guide section 130, 330 Light irradiation pad 150 Light irradiation pad set B Child NS Non-irradiated surface (of light irradiation pad) S Irradiated surface (of light irradiation pad)
