Description

  The present invention relates to an infant posture maintaining structure that appropriately maintains an infant posture and prevents a decrease in oxygen saturation.

  Various proposals have been made to maintain the infant's posture.

  For example, Utility Model Registration No. 3079785 (Patent Document 1) discloses an infant pillow. The infant pillow disclosed in this publication does not impair the shape of the baby's head by making the overall shape a donut shape or an inverted U shape.

  Japanese Patent Laying-Open No. 2003-70602 (Patent Document 2) 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.

  Japanese Patent Application Laid-Open No. 11-276312 (Patent Document 3) 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.

Japanese translations of PCT publication No. 2002-539852 (patent document 4) is disclosing the multifunctional cushion which can prevent the movement of a bed and turning over at the time of sleep of an infant. The multifunction cushion disclosed in this publication includes a thin and flat pad and a pair of cylindrical cushions positioned on both sides of the pad.
Utility Model Registration No. 3079785 (FIGS. 1-8 and related descriptions) JP 2003-70602 A JP-A-11-276312 Special Table 2002-539852

  An example of a donut-shaped infant pillow disclosed in Japanese Utility Model Registration No. 3079785 (Patent Document 1) is shown in FIG. FIG. 26 (A) is a diagram showing an example in which an infant is laid on a donut-shaped pillow, and FIG. 26 (B) is an infant pillow shown in FIG. 26 (A), where the infant's head is smaller than the donut and the neck FIG. 26C is a diagram showing a state in which only a portion is supported, and FIG. 26C is a diagram showing a state in which the baby's head is displaced from the donut-shaped pillow.

  In the donut-shaped pillow 90, the infant's head is originally lifted with a donut-shaped pillow, and the entire head is lifted so that the infant's back is not flat. However, as shown in FIG. 26 (A), only the head is positioned on the pillow, and the position of the lower part from the shoulder is not specified. Therefore, the lower part from the shoulder is placed on the head as shown by the dashed line in the figure. In some cases, it may move.

  In addition, as shown in FIG. 26 (B), when the infant's top is not supported by the donut pillow and only the neck is supported by the donut pillow, the infant's neck is lifted unnaturally, It becomes painful.

  Furthermore, as shown in FIG. 26 (C), in the state where the infant's head is removed from the pillow with the donut-shaped pillow and the head is then lifted, the neck portion may be compressed and airway obstruction may occur. .

  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 cause a decrease in 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.

  As disclosed in Japanese Patent Application Laid-Open No. 2003-70602 (Patent Document 2) and Japanese Patent Application Laid-Open No. 11-276312 (Patent Document 3), if the upper body of an infant is restrained by a band or a wearing tool, it is possible to prevent turning over. Although it is possible, the movement of the upper body of the baby is almost stopped, so it is not suitable for long-time use.

  In the case of the multifunctional cushion disclosed in JP-T-2002-539852 (Patent Document 4), only a pair of cylindrical cushions are positioned on both sides of the infant, so that the infant can freely move. . On the other hand, since a certain amount of gap is formed between the infant's side and the cushion, it is difficult to prevent the infant's neck and abdomen from bending.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide a posture maintaining structure for an infant capable of appropriately maintaining the posture of the infant and preventing a decrease in oxygen saturation. It is.

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

  The posture maintaining structure for an infant according to the present invention is provided on the left and right sides of the mat so as to abut on the mat extending vertically and horizontally and on both sides of the torso of the infant laid on the mat. A pair of torso supports positioned. Each torso support includes a lower layer part that supports the back side of the torso side of the infant from below, and an upper layer part that is positioned outwardly on the lower layer part and is in contact with the torso side part of the infant from the side.

  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.

  According to the present invention having the above configuration, the lower portion of the torso support supports the back side of the torso side of the infant from the bottom, and the upper layer portion contacts the torso side portion of the infant from the side, so that the position of the torso portion of the infant is firmly Can be held 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.

  The fetus in the mother's stomach is in amniotic fluid and is constantly under pressure on the skin throughout the body. From the memory at this time, newborns and premature babies sleep well when they feel pressure on the skin of their bodies 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 especially newborns and premature babies can sleep well in peace.

  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 more firmly fixed and held.

  In one embodiment, each torso support is detachably attached to the mat. If it does in this way, the space | interval and positional relationship of a pair of trunk | drum support can be adjusted according to the baby's body shape and body size.

  The posture holding structure for infants may include a pillow provided on the upper part 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.

  Preferably, the pillow 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, And a cervical spine support portion that supports the infant's neck positioned from below by the head positioning portion.

  While positioning the infant's head by the head positioning portion and horizontally supporting the infant's neck with the cervical vertebra support portion lower than the head positioning portion, the airway can be correctly secured without blocking the infant's airway. As a result, it is possible to provide an infant pillow that an infant can sleep with peace of mind.

  Furthermore, since the posture holding structure for infants is provided with the pillow as described above, it is possible to prevent the neck from being bent and to prevent the oxygen saturation from decreasing.

  Preferably, the height of the head positioning portion facing the nose and mouth of the baby is lower than the height of the baby's nose and mouth when the baby turns the neck and turns sideways on the cervical support. Since the height of the head positioning part is set in this way, even if the baby turns sideways, it does not suffocate.

  In addition, a pair of head positioning part may mutually be continued by the top part side.

  More preferably, the cervical spine support has a trapezoidal shape having a long side on the infant's neck side. Moreover, 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 crown side to the neck side.

  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.

  Since the shoulder pad portion extending from the head positioning portion is provided to position the baby's shoulder, the baby's head and shoulder are positioned. As a result, the infant's head and body are less likely to twist and airway obstruction is less likely to occur.

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

  An embodiment of the present invention will be described below with reference to the drawings. 1 is a perspective view of an 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.

  Referring to FIGS. 1 and 2, an infant pillow 10 is composed of an underlay layer 11 and a relatively soft cloth on the underlay layer 11, and a head positioning raised in an inverted U shape with respect to the upper end portion. Part 12 and a cervical vertebra support part 13 provided in the central part 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.

  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 recessed part 15 are each smoothly connected.

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

  Referring to FIG. 4, the heights of both sides of the head positioning part 12 are substantially constant from the upper end part to a slightly upper position of the cervical vertebra support part 13, and gradually increase from there to the end part of the projecting part 14. It is falling. In addition, the height of the part of the both sides 12a and 12b of the head positioning part 12 that faces the infant's nose and mouth when the infant faces sideways on the cervical vertebra support part 13 is the height of the infant's nose and mouth. The dimension is lower than this. This height prevents suffocation even if the baby is facing sideways.

  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 can be received in the recess 15 (see FIG. 3), the position of the infant's head 18 is determined as the head positioning. Positioned by part 12. The left and right shoulders of the baby are also positioned by the first and second protrusions 14a and 14b. Since 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 prior art. In addition, since the infant's neck is supported by the cervical vertebra support portion 13, when the infant is laid down, the neck becomes horizontal, and the neck portion is lifted and becomes cramped as in the conventional case. There is no such thing as airway obstruction due to lowering.

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

FIG. 5 is a graph showing changes in oxygen saturation (SpO ₂ : measured value by pulse oximeter) and pulse rate in the sleeping state of the infant when the infant pillow 10 according to this embodiment is used. is there. When the infant is laid on the infant pillow 10 (A), when the infant pillow 10 is lost (B), and when the infant pillow 10 is applied again (C), the infants are placed side by side for comparison. Show. The pulse is normal in all data.

  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 is asleep. It turns out that (B) oxygen saturation falls 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. Thereafter, when the infant pillow 10 is applied again (C), the oxygen saturation level rises again (up to around 95). From FIG. 5, the effect of this infant pillow 10 is clear.

  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 apparatus such as a stroller.

  Referring to FIG. 6, an infant pillow 20 is built in conformity with the inner wall surface of the stroller 21. The shape of the infant pillow is basically the same as that shown in FIGS. Thus, if the infant pillow 20 is adapted to or fixed to the inner wall surface of a baby-care device such as a stroller, the infant's head and shoulders are firmly positioned within the child-care device, and there is no airway obstruction. Infants can sleep.

  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 baby-care device such as the stroller 21 on which the infant pillow 20 is placed, and the infant pillow 20 is placed thereon. It is necessary to avoid being affected by the hardness of the upper surface of the child-care equipment.

  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. With reference to FIGS. 7 and 8, the infant pillow 30 according to this embodiment is such that the head positioning portion 32 has a donut shape with respect to the previous embodiment shown in FIGS. And the point that the protrusion part is not provided differs in the point that the cervical vertebra support part 33 is a rectangle. Since the part other than the above is basically the same as that of 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 will be given. Omitted.

  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 a 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 head 46 on the left and right head positioning portions 42 a, It is divided into 42b. The head positioning part 42 and the cervical vertebra support part 43 rise from the underlay layer 41 relatively abruptly.

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

  Next, still another embodiment of the present invention will be described. 11 is a plan view showing still another embodiment, and FIG. 12 is a cross-sectional view of a portion indicated by XII-XII in FIG. With reference to FIG. 11 and FIG. 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 protrusions 52a, 53a and 52b, 53b. By providing the grooves 56a and 56b in this manner, the baby suffocates if the baby turns sideways while the baby is sleeping and there are no portions to the baby's nose and mouth when the baby turns sideways. There is nothing.

  Further, the grooves 56a and 56b extend from the center in FIG. 11 to a position where the nose does not contact even when the baby turns sideways (near the position indicated by the alternate long and short dash line in FIG. 11). (Refer to the portion of the dashed line in FIG. 12). Even if it does in this way, the effect similar to the above is acquired.

  The portions other than the above are basically the same as those in the previous embodiment, including that the portion surrounded by the protrusions 52a, 53a, 52b, 53b and the cervical vertebra support portion 43 constitutes the recess 45. Since there is, the description is abbreviate | omitted.

  FIG. 13 is a perspective view showing an infant posture holding tool 60 of an 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 where the baby is laid on the baby posture holder 60. The illustrated baby posture holder 60 includes a mat 61 extending vertically and horizontally and a pair of left and right sides of the mat 61 so as to abut on both sides of the torso 100 of the baby laid on the mat. And trunk supports 62 and 63. The torso supports 62 and 63 are respectively positioned on the lower side portions 62b and 63b that support the rear side of the infant torso 100 from below, and are shifted outwardly on the lower layer portions 62b and 63b. And upper layer portions 62a and 63a that are in contact with the portion 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.

  The baby posture holder 60 may be used on indoor tatami mats, futons, cribs, etc., and may be used on baby-care equipment such as baby carriages, child seats, and childcare chairs.

  In the illustrated embodiment, the upper layer portions 62a and 63a and the lower layer portions 62b and 63b of the trunk supports 62 and 63 are respectively columnar bodies having an elliptical cross-sectional shape. The upper layer portions 62a and 63a and the lower layer portions 62b and 63b are connected by an appropriate joining means. For example, they may be sewn or may be detachably connected via a hook-and-loop fastener.

  Since the torso supports 62 and 63 are in contact with both sides of the torso of the infant, the upper layer parts 62a and 63a and the lower layer parts 62b and 63b are preferably flexible so as to give a soft feel to the infant. It is made of a material with a property. 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.

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

  The trunk supports 62 and 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 detachable, the distance and positional relationship between the pair of torso supports can be adjusted according to the baby's body shape and body size. Needless to say, even in the case of a structure in which each cylinder support is mounted on the mat so that the cylinder supports cannot be attached and detached, it is possible to adjust the interval and positional relationship between the pair of cylinder supports.

  The infant posture holder 60 shown in the figure includes a pillow 10 attached to an upper portion 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 FIGS. 1 to 4, its description is omitted. Needless to say, instead of the pillow 10 shown in FIGS. 1 to 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. May be used.

  The pillow 10 may be completely fixed to the upper part 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.

  By providing the infant posture holder 60 with the pillow 10 as described above, it is possible to prevent bending of the neck of the infant and prevent a decrease in oxygen saturation.

  FIGS. 16 and 17 show a state where the baby is laid on the baby in the supine position on the baby posture holder 60. In the state shown in FIG. 16, since the infant raises both hands to the head side, the pair of torso supports 62 and 63 are positioned below the infant's side. In the state shown in FIG. 17, since the infant has both hands lowered, the pair of torso supports 62, 63 supports the infant's arms from below. Thus, according to the illustrated embodiment, both arms of the infant are not cramped even when the pair of torso supports 62 and 63 are present, so that the infant is not uncomfortable.

  FIG. 18 is a graph showing changes in oxygen saturation when the infant posture holder 60 is used (solid line) and when not used (dotted line) in a state where a two-month-old infant is in a supine position. It is. 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, when the infant posture holder 60 was used, no decrease in oxygen saturation was observed.

  FIG. 19 shows the case where the infant posture holder 60 is used in a state where the backrest part is raised at an inclination angle of 30 degrees with respect to the seat part (solid line) and when it is not used (dotted line). It is a graph which shows the change of the oxygen saturation of the infant of 2 months after birth. When the infant posture holder 60 was not used, a state in which the oxygen saturation was lowered was continuously observed. This is presumably because the back and back are raised and the infant's neck and abdomen are easily bent. On the other hand, when the infant posture holder 60 was used, no decrease in oxygen saturation was observed.

  If the mat 61 is made of a material having a certain degree of shape retention, it becomes easy to hold the baby lying on the baby posture holder 60 together with the baby posture holder. Therefore, for example, it becomes easy to lower the baby from the seat of a child-care device such as a baby carriage or a child seat, or to put the baby on the seat.

  20 and 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 trunk 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. When the baby is not laid on the posture holder 70, the central portion of the band 74 is separated from the mat 71 upward.

  As shown in FIG. 21, when the baby is laid on the posture holder 70, the central portion of the belt 74 is pressed downward by the baby's torso 100. The upper layer portions 72a and 73a are moved inward.

  22 and 23 show still another example of the infant posture holder. The illustrated posture holder 80 for infant includes a mat 81 and a pair of trunk supports 82 and 83. Each torso support 82, 83 has a lower layer part 82 b, 83 b that supports the back side of the infant's torso side part from below, and an upper layer part that is displaced outwardly on this lower layer part and abuts against the infant's torso side part from the side 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. In a state where the baby is not laid on the posture holder 80, the inner end portions of the rigid members 84 and 85 are largely separated upward from the mat 81.

  As shown in FIG. 23, when the baby is laid down on the posture holder 80, the inner ends of the rigid members 84, 85 are pushed downward, so that each rigid member 84, 85 is indicated by an arrow A in FIG. The upper layer portions 82a and 83a are moved inwardly.

  24 and 25 show still another example of the infant posture holder. The infant posture holder 110 shown in the figure includes a mat 111, a pair of trunk supports 112, 113, and a standing wall section 114 that extends from the pair of trunk supports and surrounds the peripheral edge of the mat 111. The standing wall 114 has a predetermined height and surrounds the lower half of the infant. The mat 111 is provided with a notch 115 for inserting a crotch belt attached to a child-care instrument.

  As shown in FIG. 25, each torso support 112, 113 has a lower layer portion 112b, 113b that supports the back side of the infant's torso from below, and a torso side portion of the infant that is displaced outwardly on this lower layer portion. And upper layer portions 112a and 113a that are in contact with each other from the side. In the illustrated embodiment, the fabric forming the mat 111 covers the lower layer portions 112b and 113b and the upper layer portions 112a and 113a.
