 Specification

 Infant posture holding structure and infant pillow

 Technical field

 TECHNICAL FIELD [0001] The present invention relates to an infant posture holding structure that appropriately maintains an infant posture and prevents a decrease in oxygen saturation and an infant pillow that does not cause airway obstruction.

 Background art

 [0002] Various proposals for maintaining the posture of an infant have been made.

[0003] For example, Utility Model Registration No. 3079785 discloses an infant pillow. The infant pillow disclosed in this report does not impair the shape of the baby's head by making the whole shape donut-shaped or inverted U-shaped.

 [0004] Japanese Patent Application Laid-Open No. 2003-70602 discloses a rug that can prevent an infant from turning over when changing the baby's diaper. In the infant rollover prevention rug disclosed in this publication, a band for fixing the infant's chest circumference and a band for fixing the left and right shoulders are attached to the rug.

 [0005] Japanese Patent Application Laid-Open No. 11-276312 discloses a roll-over prevention tool that is convenient for use when changing diapers of infants. In the roll-over prevention tool disclosed in this publication, a wearing tool that can be worn on the upper body of an infant is attached to a rug.

 [0006] Japanese Patent Application Publication No. 2002-539852 discloses a multi-functional cushion that can prevent the bed from moving and turning over when the baby sleeps. The multi-function cushion disclosed in this publication includes a thin and flat pad and a pair of cylindrical cushions positioned on both sides of the pad.

 [0007] An example of a donut-shaped infant pillow disclosed in Utility Model Registration No. 3079785

 Shown in 26A, 26B, 26C. Fig.26A is a diagram showing an example in which an infant is laid on a donut-shaped pillow, and Fig.26B is a diagram of the infant pillow shown in Fig.26A in which only the neck where the infant's head is smaller than the donut is supported. FIG. 26C is a diagram showing a state in which the baby's head is displaced from the donut-shaped pillow.

[0008] In the donut-shaped pillow 90, the infant's head is originally lifted with a donut-shaped pillow to lift the entire head so that the infant's occipital region does not become flat. Figure 2 As shown in 6A, only the head is positioned on the pillow and the position below the shoulder is not specified, so the part below the shoulder moves relative to the head as shown by the dashed line in the figure. There may be cases.

 [0009] Also, as shown in FIG. 26B, if the top of the infant is not supported by the donut pillow and only the neck is supported by the donut pillow, the infant's neck is unnaturally lifted, It becomes painful.

 [0010] Further, as shown in FIG. 26C, in the state where the infant's head is removed from the pillow with the donut-shaped pillow and then the head is lifted, the neck may be compressed and airway obstruction may occur. The

[0011] When an infant frequently turns over in the supine position, the infant often has a cramped posture as shown in FIG. In the state shown in Fig. 27, the infant's neck is bent, which may reduce oxygen saturation due to airway obstruction. Furthermore, since the baby's abdomen is also bent and compressed, abdominal breathing may be hindered and oxygen saturation may be reduced.

 [0012] As disclosed in Japanese Patent Laid-Open No. 2003-70602 and Japanese Patent Laid-Open No. 11-276312, it is possible to prevent turning over if the upper body of the infant is restrained by a belt or a wearing tool.

It is not suitable for long-time use because it almost stops the movement of the baby's upper body.

 [0013] In the case of the multi-functional cushion disclosed in JP-T-2002-539852, the pair of cylindrical cushions are only positioned on both sides of the infant, so that the infant can freely move. On the other hand, since a certain gap is formed between the infant's side and the cushion, it is difficult to prevent the infant's neck and abdomen from bending.

 Disclosure of the invention

 [0014] The present invention has been made in order to solve the above-described problems, and an object of the present invention is to maintain an infant posture appropriately and prevent a decrease in oxygen saturation. Is to provide.

 [0015] Another object of the present invention is to provide an infant posture holding structure capable of preventing the neck and abdomen of the infant from bending.

[0016] Still another object of the present invention is to provide an infant pillow that allows an infant to sleep with peace of mind. It is.

 [0017] The posture holding structure for an infant according to the present invention includes a mat extending vertically and horizontally, and left and right sides of the mat so as to come into contact with both sides of the infant's torso that is lying on the mat. A pair of torso supports located on the sides. Each torso support includes a lower layer portion that supports the back side of the torso side of the infant from below, and an upper layer portion that is positioned outwardly on the lower layer portion and abuts against the infant's torso side portion from the side.

 [0018] Preferably, the upper layer portion and the lower layer portion constituting the trunk support are formed of a flexible material. For example, the upper layer portion is formed from a foam material having a high expansion ratio, and the lower layer portion is formed from a foam material having a lower expansion ratio than the upper layer portion.

 [0019] According to the present invention having the above-described configuration, the lower portion of the torso support supports the back side of the torso side of the infant from below, and the upper layer portion also abuts on the torso side portion of the infant, so The position can be held firmly and fixed. Therefore, since the abdomen is not bent and compressed, normal abdominal breathing can be maintained and a decrease in oxygen saturation can be prevented.

 [0020] The fetus in the mother's stomach is in amniotic fluid and is constantly under pressure on the whole body skin by water pressure. From memory at this time, newborns and premature babies sleep well in peace when they feel pressure on their skin so that they are wrapped in a large area. According to the present invention having the above-described configuration, the pair of torso supports apply pressure so as to wrap the torso of the infant, so that newborns and premature infants can sleep well in peace.

 [0021] Preferably, the upper layer portion is configured to move inward as the lower layer portion is pressed by the weight of the infant. In this way, the torso portion of the infant can be fixed and held more firmly.

 [0022] In one embodiment, each torso support is detachably attached to the mat. In this way, the distance and positional relationship between the pair of torso supports can be adjusted according to the baby's body shape and body size.

 [0023] The posture holding structure for an infant may include a pillow provided on an upper portion of the mat so as to support the head of the infant sleeping on the mat from below. The pillow is detachably attached to the mat, for example.

[0024] Preferably, the pillow has a first height, and supports a pair of both sides of the infant's occipital region from below. A head positioning portion; and a cervical vertebra support portion having a second height lower than the first height and supporting the infant's neck positioned by the pair of head positioning portions from below.

[0025] The infant's head is positioned by the head positioning part, and the infant's neck is horizontally supported by the cervical vertebra support part lower than the head part positioning part, so that the infant's airway is obstructed and the airway is properly secured. it can. As a result, it is possible to provide an infant pillow that allows infants to sleep safely.

 [0026] Further, since the posture holding structure for infants includes the pillow as described above, it is possible to prevent bending of the neck portion and to prevent a decrease in oxygen saturation.

[0027] Preferably, the height of the head positioning portion facing the infant's nose and mouth when the infant rotates and necks on the cervical support is such that the height of the infant's nose and mouth is Lower than the height. Since the height of the head positioning part is set in this way, even if the baby turns sideways, it will not suffocate.

 [0028] Note that the pair of head positioning portions may be continuous with each other on the top side.

 [0029] More preferably, the cervical spine support portion has a trapezoidal shape having a long side on the infant neck side.

 In addition, it is preferable that the height of the pair of head positioning portions is formed so as to gradually decrease from the top to the neck. Furthermore, it is preferable that the cervical vertebra support portion is formed so as to be gradually lowered from the parietal side to the neck side.

[0030] More preferably, the pair of head positioning portions extend on the neck side from the cervical vertebra support portion on the neck side, thereby constituting a shoulder rest portion for positioning the infant's shoulder.

[0031] Because a shoulder pad portion extending from the head positioning portion is provided to position the infant's shoulder

The baby's head and shoulders are positioned. As a result, the infant's head and body are less likely to twist, causing airway obstruction.

[0032] The infant posture holder may further include a standing wall portion that surrounds the periphery of the mat so as to surround the lower body of the baby in a row from the pair of torso supports.

[0033] The infant pillow according to the present invention has a first height, a pair of head positioning portions that support both sides of the infant's occipital region from below, and a second height lower than the first height. A cervical vertebra support portion having a height and supporting the infant's neck from below positioned by a pair of head positioning portions; Brief Description of Drawings

 BEST MODE FOR CARRYING OUT THE INVENTION

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of the infant pillow 10, FIG. 2 is a plan view thereof, and FIGS. 3 and 4 are cross-sectional views taken along lines III-III and IV-IV of FIG.

 [0036] Referring to FIGS. 1 and 2, the infant pillow 10 is formed in an inverted U shape with respect to the upper end portion, which is composed of an underlay layer 11 and a relatively soft cloth on the underlay layer 11. It has a raised head positioning part 12 and a cervical support part 13 provided at the center near the lower end of the infant pillow 10. The cervical vertebra support portion 13 is a raised portion having a trapezoidal shape with a long side on the lower end side.

 [0037] The inverted U-shaped head positioning portion 12 extends downward from the cervical vertebra support portion 13, and constitutes first and second protrusions 14a and 14b. A portion surrounded by the head positioning portion 12 and the cervical vertebra support portion 13 constitutes a recess 15. The head positioning part 12, the cervical vertebra support part 13, and the recess 15 are smoothly connected to each other.

 [0038] Referring to FIG. 3, the height of the highest portion of cervical vertebra support portion 13 is lower than the height of the top side of head positioning portion 12 and smoothly descends from there to the upper end side and the lower end side. Yes. By making the cervical support 13 in such a taper shape, as will be described later, when the infant is laid on the infant pillow 10, the fat from the neck to the shoulder of the infant with almost no neck portion is reduced. This part can be supported.

Referring to FIG. 4, the height of both sides of the head positioning part 12 is substantially constant from the upper end part to a slightly upper side of the cervical vertebra support part 13, and from there the end of the protrusion part 14 It gradually decreases to the part. It should be noted that the infant on the cervical support 13 on both sides 12a and 12b of the head positioning unit 12 The height of the part facing the infant's nose and mouth when facing sideways is smaller than the infant's nose and mouth height. This height will prevent you from suffocating even if your baby turns sideways.

 [0040] In the infant pillow 10 having such a shape, when the infant's head 18 is applied to the infant's head so that the head is in the recess 15 (see Fig. 3), the position of the infant's head 18 is Positioned by the head positioning unit 12. Also, the left and right shoulders of the infant are positioned by the first and second protrusions 14a and 14b. Because the infant's head 18 and shoulders can be positioned, there is no risk of the infant's body being twisted during sleep as in the past. In addition, since the infant's neck is supported by the cervical vertebra support part 13, when the baby is laid down, the neck becomes horizontal, and the neck part is lifted and cramped as in the conventional case. It ’s not going to be too low and the airway becomes obstructed.

 [0041] In order to maintain the height relationship as the infant pillow 10, the material constituting the underlay layer 11 is the head positioning part 12, the cervical spine support part 13 and the first and second parts formed thereon. It is preferable that the density is higher than the material constituting the protrusions 14a and 14b.

 [0042] Fig. 5 shows changes in oxygen saturation (SpO: measured value by pulse oximeter) and pulse rate in the sleep state of the infant when the infant pillow 10 according to this embodiment is used.

 2

 It is a graph to show. To compare each of the cases where the infant is laid on the infant pillow 10 (A), when the infant pillow 10 is removed (B), and when the infant pillow 10 is applied again (C) Shown side by side. The pulse is normal in all data.

 [0043] As can be seen from FIG. 5, when the infant pillow 10 is used (A), the infant does not show a decrease in oxygen saturation (near 95) and sleeps. It can be seen that the oxygen saturation decreases after a while after removing the infant pillow 10 (down to about 85). This is because the neck is gradually twisted due to turning over, and the oxygen saturation is lowered. After that, when the infant pillow 10 is applied again (C), the oxygen saturation rises again (up to around 95). From Fig. 5, the effect of this infant pillow 10 is clear.

[0044] Next, another embodiment of the present invention will be described. FIG. 6 is a plan view showing another embodiment of the present invention. In this embodiment, the infant pillow 20 is built into an infant childcare device such as a baby beaker. Referring to FIG. 6, an infant pillow 20 is incorporated in conformity with the inner wall surface of stroller 21. The shape of this infant pillow is basically the same as that shown in FIG. In this way, the force to fit the infant pillow 20 to the inner wall of a child-care device such as a beaker, or, if fixed, the force and positioning of the baby's head and shoulders within the child-care device Infants can sleep without airway obstruction.

 [0046] In this case, the underlay layer 11 is formed of a material having a density higher than that of the material forming the upper surface of the child-care device such as the beaker 21 on which the infant pillow 20 is placed, and the infant pillow 2 It is necessary to avoid being affected by the hardness of the upper surface of the child-care device on which 0 is placed.

 Next, still another embodiment of the present invention will be described. FIG. 7 is a plan view of an infant pillow showing still another embodiment of the present invention, and FIG. 8 is a sectional view of a portion indicated by VIII-VIII in FIG. 7 and 8, the infant pillow 30 according to this embodiment is different from the previous embodiment shown in FIG. 1 in FIG. 4 in that the head positioning portion 32 has a donut shape. The difference is that the protrusion is not provided and the cervical support 33 is rectangular. Since the part other than the above is basically the same as the previous embodiment, including the point that the part surrounded by the head positioning part 32 and the cervical vertebra support part 33 constitutes the concave part 35, the description thereof is Omitted.

 [0048] The infant pillow 30 in this embodiment basically has the same basic shape as that of the previous embodiment, and therefore has the same effect as that of the previous embodiment.

 Next, still another embodiment of the present invention will be described. FIG. 9 is a plan view showing still another embodiment, and FIG. 10 is a cross-sectional view of the portion indicated by XX in FIG. With reference to FIGS. 9 and 10, in the infant pillow 40 according to this embodiment, unlike the previous embodiment, the head positioning portion 42 has a left and right head positioning portions 42a, 42a, It is divided into 42b. In addition, the head positioning part 42 and the cervical vertebra support part 43 rise relatively rapidly from the underlying layer 41.

 [0050] The other parts are basically the same as those of the previous embodiment, and the description thereof is omitted. Since the infant pillow 40 in this embodiment basically has the essential parts in the previous embodiment, the same effects as in the previous embodiment can be obtained.

[0051] Next, still another embodiment of the present invention will be described. Figure 11 shows yet another example. FIG. 12 is a plan view showing an embodiment, and FIG. 12 is a cross-sectional view of a portion indicated by XII-XII in FIG. 11 and 12, in the infant pillow 50 according to this embodiment, unlike the previous embodiment, each of the pair of head positioning portions 42a, 42b in the previous embodiment It is divided into two projections 52a, 53a and 52b, 53b. By providing the grooves 56a and 56b in this way, the baby suffocates if he or she turns sideways while the baby is sleeping and there are no parts to the baby's nose and mouth when the baby turns sideways. There is nothing.

 [0052] In addition, the grooves 56a and 56b are located at the positions where the nose does not come into contact with the baby even when the baby faces sideways from the center in FIG. 11 (near the position indicated by the dashed line in FIG. 11). The outside may have a slight height (see the dashed line in Figure 12). Even in this way, the same effect as described above can be obtained.

 [0053] The portions other than the above are basically the same as those described above, including that the portion surrounded by the protrusions 52a, 53a, 52b, 53b and the cervical vertebra support portion 43 constitutes the recess 45. Since it is the same as the form, the description is omitted.

 FIG. 13 is a perspective view showing an infant posture holding tool 60 of one embodiment of the infant posture holding structure according to the present invention, and FIG. 14 is a cross-sectional view thereof. FIG. 15 is a cross-sectional view showing a state in which the baby is sleeping on the baby posture holder 60. The infant posture holder 60 shown in the figure is a pair of mats 61 that are positioned on the left and right sides of the mat 61 so as to abut against both sides of the torso 100 of the infant to be laid on the mat. Body support 62, 63. The monthly supports 62, 63 are respectively positioned on the lower layer 62b, 63b that supports the rear side of the infant's monthly 100 from below, and on the lower part 62b, 63b, shifted outwardly and positioned on the infant's torso 100. And upper layer portions 62a and 63a that are in contact with the side portions from the side. In FIG. 15, the infant's arms 101 and 102 are placed on the upper layers 62a and 63a of the torso support.

 [0055] The infant posture holder 60 may be used on an indoor tatami mat, a futon, a crib, or the like, or may be used on a child-care device such as a baby carriage, a child seat, or a child-care chair.

 [0056] In the illustrated embodiment, the upper layer portions 62a, 63a and the lower layer portions 62b,

Each of 63b is a columnar body having an elliptical cross-sectional shape. The upper layer parts 62a, 63a and the lower layer parts 62b, 63b are connected by an appropriate joining means. For example, even if you sew them Good, and you can connect it detachably via a hook-and-loop fastener.

 [0057] Since the torso supports 62 and 63 abut against both sides of the infant's torso, the upper layer portions 62a and 63a and the lower layer portions 62b and 63 are preferably provided so as to give a soft feel to the infant. b is formed of a flexible material. For example, the upper layer portions 62a and 63a may be formed of a foam material having a high expansion ratio, and the lower layer portions 62b and 63b may be formed of a foam material having a lower expansion ratio than the upper layer portion.

 [0058] As shown in FIG. 15, the lower portions 62b, 63b of the torso supports 62, 63 are pushed to the side and back of the infant's torso 100 so as to fill the gap between the infant's back and the mat 61. To spread. Further, as the lower layer parts 62b and 63b are pressed and deformed by the weight of the infant, the upper layer parts 62a and 63a move inwardly and come into contact with both sides of the trunk 100 from the side. Therefore, according to the illustrated embodiment, the force S can be firmly and stably fixed and held in the position of the torso portion of the infant. In this way, for example, it is possible to prevent bending of the baby's abdomen during sleep and to prevent a decrease in oxygen saturation.

 [0059] The trunk supports 62, 63 may be completely fixed on the mat 61, or may be detachably attached via a hook-and-loop fastener or the like. If each torso support is removable, it is possible to adjust the distance and positional relationship between the pair of torso supports according to the baby's body shape and body size. Needless to say, it is possible to adjust the distance and the positional relationship between the pair of cylinder supports even in the case of mounting on the mat so that each cylinder support cannot be attached and detached.

 The infant posture holder 60 shown in the figure includes a pillow 10 attached to the top of the mat 61 so as to support the head of the infant sleeping on the mat 61 from below. Since this pillow 10 is the same as that shown in FIG. 1 and FIG. 4, its description is omitted. Needless to say, instead of the pillow 10 shown in FIG. 1 and FIG. 4, the pillow 20 shown in FIG. 6, the pillow 30 shown in FIG. 7, the pillow 40 shown in FIG. 9, and the pillow 50 shown in FIG. You can use it.

 [0061] The pillow 10 may be completely fixed to the upper portion of the mat 61, or may be detachably attached via a hook-and-loop fastener or the like. Preferably, the position of the pillow 10 can be adjusted according to the size of the infant's body.

[0062] Since the infant posture holder 60 includes the pillow 10 as described above, the infant's neck is bent. Prevents oxygen saturation from decreasing.

 FIG. 16 and FIG. 17 show a state where the infant is laid on the infant's posture holding tool 60 in the supine position. In the state shown in FIG. 16, since the infant raises his hands to the head, the pair of torso supports 62 and 63 is located below the infant's side. In the state shown in FIG. 17, since the infant has both hands lowered, a pair of torso supports 62 and 63 supports the infant's arms from below. Thus, according to the illustrated embodiment, even if there is a pair of torso supports 62, 63, the infant's arms do not become cramped, so that the infant is not uncomfortable.

 [0064] Fig. 18 shows the oxygen saturation levels when the infant's posture holder 60 is used in the supine position with a 2-month-old infant in the supine position (solid line) and when it is not used (dotted line). It is a graph showing changes. When the infant posture holder 60 was not used, it was observed that the oxygen saturation was greatly reduced when the infant's body moved. On the other hand, no decrease in oxygen saturation was observed when the infant posture holder 60 was used.

 [0065] Fig. 19 shows the case where the infant posture retainer 60 is used with the backrest portion raised at an inclination angle of 30 degrees with respect to the seat (solid line) and the case where it is not used (dotted line). Is a graph showing the change in oxygen saturation of an infant 2 months after birth. When the infant posture holder 60 was not used, the oxygen saturation continued to decline. This is thought to be due to the fact that the back and back are raised and the neck and abdomen of the infant are more easily bent. On the other hand, when the infant posture holder 60 was used, the oxygen saturation was not reduced.

 [0066] If the mat 61 is made of a material having a certain degree of shape retention, it is possible to hold the baby sleeping on the infant posture holder 60 together with the baby posture holder. It becomes easy. Therefore, for example, it becomes easy to lower the baby from the seat of childcare equipment such as a baby carriage or a child seat, or to put the baby on the seat.

FIG. 20 and FIG. 21 show another example of the infant posture holder. The infant posture holder 70 shown in the figure includes a mat 71, a pair of trunk supports 72 and 73, and a belt 74. Each cylinder support 72, 73 includes upper layer portions 72a, 73a and lower layer portions 72b, 73b, as in the above-described embodiment. Both ends of the belt 74 pass between the upper layer portions 72a and 73a and the lower layer portions 72b and 73b of the trunk supports 72 and 73 and are connected to both side walls 75 forming a seat. Infants hold posture When not lying on the implement 70, the central portion of the strip 74 is spaced upward from the mat 71.

 [0068] As shown in FIG. 21, when the infant is laid on the posture holder 70, the central portion of the band 74 is pressed downward by the infant's torso 100. The upper layers 72a and 73a of the supports 72 and 73 are moved inward.

 FIG. 22 and FIG. 23 show still another example of the infant posture holder. The illustrated baby posture holder 80 includes a mat 81 and a pair of trunk supports 82 and 83. Each torso support 82, 83 is located on the lower side of the lower part 82b, 83b that supports the back side of the infant's torso from below, and is laterally displaced on this lower part, and a lateral force also abuts against the infant's torso side part. Includes upper layer parts 82a and 83a. As shown in the figure, plate-like rigid members 84 and 85 that are curved downwardly are accommodated in the trunk supports 82 and 83, respectively. When the baby is not lying on the posture retainer 80, the inner ends of the rigid members 84, 85 are far away from the mat 81.
