Definitions

  • the present invention relates to a turnable side sleeping auxiliary backpack, which is used for assisting persons with obstructive sleep apnea and/or snoring and pregnant women to avoid the supine sleeping posture during sleep.
  • the sleeping position of pregnant women is closely related to the health of mother and child.
  • the uterus gradually increases in late pregnancy.
  • the uterus When lying on the back, the uterus may compress the kidneys, reducing the blood flow of the kidneys and the glomerular filtration rate, which affects the health of pregnant women and fetuses.
  • the enlarged uterus when lying on the back may also compress the inferior vena cava, blocking the blood return of the inferior vena cava, causing edema and varicose veins of the lower extremities.
  • due to the reduction of blood return to the heart the blood supply to the whole body is reduced, causing symptoms such as chest tightness, nausea, vomiting, and blood pressure drop, which is medically called "supine hypotension syndrome". It is generally emphasized that it is not advisable to lie on your back for a long time after 6 months of pregnancy.
  • the prior art offers only limited options and is very limited. Some patients sewed tennis balls, golf balls and other objects to the back of their pajamas to form protrusions, hoping that the pressure on the back of the protrusions would help them get out of the supine posture.
  • the limitations of this technology are: First, the protrusions tend to move with the garment and deviate from the center of the back. Second, the user cannot adjust the side lying angle. Third, the protrusions are small in size, making it difficult to achieve the necessary lateral lying angle. Especially when the mattress is soft, the protrusions may sink into the bed and cause failure. Fourth, localized pressure on the bulge can lead to back or spine injuries.
  • US20120167895A1 describes a belt for avoiding supine sleeping, and is similar to WO2007130931A1 and WO2016176632A1.
  • Such techniques include a strap that wraps around the human torso and a projection fixed to the strap at a mid-back position that disrupts the stable balance of the supine position.
  • the limitations of this technique are: First, if the protrusion is small, it is difficult to achieve the necessary lateral lying angle. Especially when the mattress is soft, the protrusions may sink into the bed and cause failure. If the protrusion is large, it is difficult for the user to turn over. Second, the user cannot adjust the side lying angle.
  • the straps are fixed around the torso, it is easy to rotate around the torso, causing the protrusions to deviate from the mid-back position.
  • the binding force is concentrated in one belt, which is easy to bring discomfort. Especially if the strap is wrapped around the chest, it can cause discomfort to female users.
  • EP3117805A1 discloses a wearable lateral sleeping aid.
  • the device fixes a lumbar pillow on the waist back of the vest, and uses the lumbar pillow to prevent the user from lying on the side from lying on the back.
  • the limitations are: first, if the volume of the lumbar pillow is large, it is difficult for the user to turn over. If the volume of the lumbar pillow is small, the necessary lateral sleeping angle cannot be achieved. Second, the user cannot adjust the side lying angle. Third, it is impossible to take into account the firmness and comfort. If the vest is thick, it is not comfortable enough; if the vest is thin, the waist pillow will easily move with the vest. Fourth, the vest has poor adaptability to different statures.
  • a backpack that avoids lying on the back disclosed in DE202014003665U1 is a relatively advanced technical solution at present.

Description

一种可翻身的侧卧辅助背包 技术领域
本发明涉及一种可翻身的侧卧辅助背包，用于辅助在睡眠中存在阻塞性睡眠呼吸暂停症和/或打鼾者以及孕妇避免仰卧睡眠姿态。
背景技术
睡眠姿态对阻塞性睡眠呼吸暂停症和打鼾的影响早已为人所知。患者在仰卧睡眠时，上呼吸道咽喉部位的部分组织位于呼吸道上方且处于松弛状态，在重力作用下向呼吸道塌陷，导致呼吸阻力增大。如果上述组织肥大或增生，会加重呼吸道的阻塞。在侧卧睡眠时，上述组织受到重力的方向指向身体一侧，不会压住呼吸道，从而减小呼吸受阻的机会。研究表明，仰卧睡眠造成的睡眠呼吸暂停症和打鼾至少是侧卧睡眠的两倍。对于许多人来说，避免仰卧睡眠姿势，可以减少甚至防止睡眠呼吸暂停症和/或打鼾。
孕妇的睡眠姿势与母子健康关系密切。妊娠后期子宫逐渐增大，仰卧时子宫可能压迫肾脏，使肾脏血流量减少，肾小球滤过率下降，影响孕妇和胎儿的健康。此外，仰卧时增大的子宫还可能压迫下腔静脉，使下腔静脉血液回流受阻，引起下肢水肿和静脉曲张。同时，由于回心血量减少,造成全身供血量减少，引起胸闷、恶心、呕吐、血压下降等症状，医学上称之为“仰卧位低血压综合征”。一般强调怀孕6个月以后不宜长时间仰卧。
在避免仰卧睡眠方面，现有技术只提供了有限的选择，且局限性很大。有患者自行将网球、高尔夫球等物体缝在睡衣的后面形成凸起，希望凸起物对背部的压力帮助其脱离仰卧姿态。该技术的局限性在于：第一，凸起物容易随着衣服移动，偏离背部正中位置。第二，使用者无法调整侧卧角度。第三，凸起物体积较小，难以达成必要的侧卧角度。特别是床垫较软时，凸起物可能陷入床内导致失效。第四，凸起物的局部压力可能导致背部或脊柱受伤。
US20120167895A1描述了一种避免仰卧睡眠的带子，与此相似的还有WO2007130931A1和WO2016176632A1。此类技术包括一个环绕人体躯干的带子和一个固定于该带子上位于背部正中位置的凸起物，通过该凸起物来破坏仰卧的稳定平衡状态。该技术的局限性在于：第一，如果凸起物体积较小，则难以达成必 要的侧卧角度。特别是床垫较软时，凸起物可能陷入床内导致失效。如果凸起物较大，则使用者难以翻身。第二，使用者无法调整侧卧角度。第三，由于带子环绕躯干固定，容易绕躯干转动，使凸起物偏离背部正中位置。第四，束缚力集中于一条带子，容易带来不适。特别是如果带子环绕于胸部附近，会给女性使用者带来不适。
EP3117805A1公开了一种可穿戴的侧卧辅助设备。该设备将一个腰枕固定于马甲的腰背部，利用腰枕来阻碍使用者由侧卧转为仰卧。其局限性在于：第一，如果腰枕体积较大，则使用者难以翻身。如果腰枕体积较小，则无法达成必要的侧卧角度。第二，使用者无法调整侧卧角度。第三，无法兼顾牢固性和舒适性，如果马甲较厚，则不够舒适；如果马甲较薄，则腰枕又容易随马甲发生位移。第四，马甲对不同身材的适应性差。
DE202014003665U1公开的一种避免仰卧的背包是目前较先进的技术方案。该背包由位于背部中部的袋子和用于固定的肩带及腹带组成。通过腰部和双肩三点固定，可以防止背包沿躯干转动，亦可较好的分散束缚力。通过填充物，背包可以保证必要的体积和强度，从而彻底避免仰卧，并提供较好的侧卧角度。其局限性在于：第一，如果背包体积较大，则使用者难以翻身；如果背包体积较小，则无法达成必要的侧卧角度。第二，因背包尺寸不可调，使用者无法调整侧卧角度。如果通过调整填充物的大小来改变侧卧角度，背包与填充物可能发生不匹配。第三，只采用双肩式固定，适用性不足。大部分使用者侧卧时身体会斜靠在背包上，位于身体下侧的肩带会受力勒紧下侧肩部造成不适。第四，采用弹力带和调节带来提高尺寸适应性，结构复杂，调节范围较小。
发明内容
本发明提供了一种用于防止患有阻塞性睡眠呼吸暂停症和/或打鼾者以及孕妇在睡眠中处于仰卧姿态的可翻身背包。本发明通过副袋结构，使背包的高度可以转化为宽度或/和长度，让使用者可以在睡眠中翻身，以保障睡眠的舒适性。调控副袋的大小，可以间接调控背包的最小隆起高度，以适应不同的使用者。背包主袋的大小可调，一方面可以彻底避免仰卧，另一方面可以帮助使用者实现不同角度的侧卧。本发明还提供了多种可靠的固定方式，使用者可选择其中最牢固和舒适的一种。另外，肩带、拉带、腹带和背板等部件使用可粘接魔术贴的材料， 配合折返粘贴技术，提升了对不同身材的适应性。综上，本发明在很大程度上避免了现有技术的缺点，提供了更具实用性和舒适性的侧卧辅助技术。
为实现上述目的，本发明提供一种可翻身的侧卧辅助背包，包括：
1.一个背板，此背板为左右对称的片状物。优选情况下，此背板在佩戴时以脊柱为对称轴左右对称。所述背板连接有腹带用于腰腹部的固定。佩戴时，腹带环绕于胸部和腹部之间的人体躯干上。作为可选项，背板连接有肩带，通常为两条，用于背包在躯干上部的固定。作为可选项，背板连接有腿带，通常为一条或两条，用于背包在臀部和/或腿部的固定。作为可选项，背板或腹带还连接有拉带，通常为两条至四条，所述拉带与所述肩带或/和腿带连接并配合使用，实现背包在躯干的固定。在特殊的实施例中，所述背板可缩小并融合为下述主袋的一部分。
2.一个或多个位于背板上的可开闭和可锁定的袋子(以下称“主袋”)。作为优选，主袋佩戴时的位置位于背部或/和臀部垂直于脊柱方向的中部。主袋的优选材料为非弹性材料，以避免在使用中沿躯干转动。主袋可以容纳一个或多个有形物体作为填充物。填充物的整体或一部分可以为弹性体。作为优选，所述填充物为一个可充放气的气囊(以下称“主气囊”)。一般情况下，主袋填充物的总体尺寸和形状与此主袋的尺寸和形状大体相同，以避免填充物无法纳入主袋或在主袋内发生位移。加入填充物后，隆起于背部的主袋可以阻挡使用者由侧卧转为仰卧。通过调整主袋和填充物的尺寸和/或形状，可以为使用者提供较为理想的侧卧角度。为更方便的调节侧卧角度，可以在主袋上设置调节件来调节其尺寸和/或形状，并同步调整填充物与之匹配。当填充物为优选的主气囊时，通过充放气即可匹配主袋的变化。
3.一个或多个与主袋连通的袋子(以下称“副袋”)。副袋的优选位置靠近背板。在侧卧状态下，所述填充物不会填满副袋。当使用者翻身，由侧卧转入仰卧状态时，填充物受到的压力增大，发生弹性形变，其一部分开始填充副袋。此时，填充物的高度逐步转化为宽度和/或长度，促使主袋的隆起高度下降，变得扁平。到达仰卧状态时，填充物承受的压力最大，副袋被填满，主袋处于最小隆起高度，让使用者可以克服背包的阻碍翻到另一侧。到达另一侧后，填充物受到的压力减小，逐步恢复原来的形状，侧卧角度也逐步增大并达成理想角度和稳定平衡状态。
为适应不同的使用者，可以在副袋上设置调节件来调节其大小，从而控制主袋在受压状态下的最小隆起高度，一方面让使用者能够克服这个障碍完成翻身，另一方面让使用者在翻身过程中不能在仰卧状态下达成稳定平衡状态，必须继续翻转到侧卧状态。
作为改进，当填充物为主气囊时，主气囊在主袋与副袋连通处连通有弹性气囊(以下称“副气囊”)。侧卧时副气囊处于收缩状态。当使用者翻身时，主气囊受压使气体进入副气囊，副气囊在副袋内充气膨胀，使主袋和主气囊变得扁平。当副气囊充满副袋时，主袋最为扁平。作为进一步改进，可在主气囊与副气囊连通处设置连接阀，副气囊在连接阀处可拆卸更换，以适应不同的使用需求。
作为进一步改进，当主袋位于腰臀部时，主袋和副袋的连接部以及主气囊和副气囊的连接部，可自后向前经由裆部弯转至身体前侧，使副袋和副气囊位于身体前侧。当主袋受压时，主气囊的气体进入副气囊，副气囊在人体前侧膨胀。其优势在于，翻身过程中副气囊不受压，膨胀范围大，对主袋的隆起高度调节范围大。
4.所述的两条肩带通过缝制方式或连接件连接于背板，肩带上可设置长度调节装置。当两条肩带分别环绕于双肩，可实现双肩式固定。当两条肩带交叉于胸前(每条肩带经由身体一侧的肩部绕过胸前到达另一侧腰腹部)，可实现胸部交叉式固定。作为改进，可设置两条与背板或腹带相连的拉带，该拉带能够与所述肩带通过连接件连接。当肩带分别与身体异侧的拉带在身体前侧连接时，可以实现胸部交叉式固定。当肩带分别与身体同侧的拉带在身体前侧连接时，可以实现双肩式固定。作为进一步改进，所述两个肩带前段各有一个环。两条拉带前段附有第一魔术贴、中段附有第二魔术贴，拉带整体为魔术贴可粘接材料制成。当两条拉带在身体前侧穿过身体异侧肩带的环后折回，用第一魔术粘于自身，即实现胸部交叉式固定。当两条拉带穿过身体同侧肩带的环后折回，用第二魔术贴粘于自身，即实现双肩式固定。上述设计提供了两种可靠的固定方式供使用者选择。拉带与肩带的衔接点可以很方便的设置于身体前侧，便于系牢和调节。拉带的魔术贴可以粘在拉带位于肩部和腰部之间的任何位置，其长度可调范围可以覆盖所有体形的使用者，不再需要另行设置弹力带、拓展带、调节卡子等调节装置。最后，肩带的环可以更好的锁定肩带和拉带的位置，折回后魔术贴粘接更加牢固。
5.所述腿带一端通过缝制方式或连接件连接于背板，腿带上可设置长度调节装置。当背包设置一条腿带时，腿带另一端自后向前经裆部绕至身体前侧，与腹带相连。当背包设置两条腿带时，腿带另一端自后向前经裆部，再绕过大腿根部后，与背板或腹带相连。当设置两条腿带时，如果每条腿带的另一端连接到身体异侧的背板或腹带上，可以实现腿部交叉式固定；如连接至身体同侧的背板或腹带，可以实现绕腿式固定。作为改进，可设置与背板或腹带相连的拉带，该拉带能够与所述腿带通过连接件连接。在设置两条腿带和两条拉带的情况下，当腿带自后向前穿过裆部后，分别与身体异侧的拉带连接，可以实现腿部交叉式固定；如腿带分别与身体同侧的拉带连接，可以实现绕腿式固定。
6.所述腹带通过缝制方式或连接件连接于背板。作为改进，可设置两条腹带，腹带整体为魔术贴可粘接材料制成。每条腹带的一端与背板连接，另一端通过魔术贴在身体前侧相连。作为进一步改进，所述一条腹带的前段有一个环，另一条腹带从其中自下向上穿过，折回后用魔术贴粘于自身表面。

具体实施方式
现结合附图对本发明作进一步的描述。
本发明的背包可以容易的用已知材料制造，无需付出很大的技术努力。
本发明所述的术语“背包”是指一条或一组闭合的带子，可固定于人体的躯干部位，所述带子上有一个或多个主体位于人体后侧可容纳有形物体的袋子。
本发明位所述的术语“背板”为左右对称的片状物，佩戴时位于背部或/和臀部。
本发明所述的术语“主袋”和“副袋”均指可容纳有形物体的袋子，除了自身可容纳有形物体的情况，亦包括其与本发明所述的背板一起构成囊状结构容纳有形物体的情况。
本发明所述的术语“拉带”是指一条或一组带子，带子的一端与背板或腹带连接，另一端与肩带或腿带连接，用于背包在人体躯干的固定。
本发明所述的术语“魔术贴”，其原意是指两片成对使用的带子，一片表面具有钩状结构，另一片表面具有环状结构，两片带子可以面对面粘接(钩)在一起。在本文中，因为技术进步，背包可以使用特殊的表层材料，这些材料能够替代传统“魔术贴”中的一片带子与所述带子中的另一片粘接(钩)在一起。因此在本文中“魔术贴”既指传统的一对带子，也指能够粘接于背包上的单片带子。
本发明所述的术语“侧卧角度”是指侧卧者背部与床面的夹角，其范围为0度至180度。睡姿越接近仰卧，侧卧角度越接近0度；睡姿越接近俯卧，侧卧角度越接近180度。较为理想的侧卧角度在90度附近。
在附图中示出了本发明的实施例，并详细描述如下。
图1、2、3、4、5、6、7为本发明的第一个实施例。背包1包含背板2，背板2为片状物，以脊柱为中心线左右对称的垫在背部。背板2的作用是连接肩带5、拉带6和腹带7，同时固定主袋3以避免其发生位移和旋转，以及分散主袋3和主气囊9对背部的支撑力。背板2可以是多层结构，靠近背部一侧可为亲肤材料，夹层可包含弹性缓冲材料以增强舒适性，还可包含较硬和较有韧性的板状定形材料以避免背包1发生形变。
背板2上端两侧分别连接两条肩带5，肩带前段设置有环10。背板2中下部两侧分别连接有两条拉带6，拉带前段设置有第一魔术贴11、中段设置有第二魔术贴12。整条拉带6为魔术贴可粘接材料制成。佩戴时，将一条拉带6从一条肩带5的环中穿过后折回，用魔术贴11或/和12粘在拉带6表面，实现背包1 在躯干上部的固定。其中第一魔术贴11用于胸部交叉式固定(图5-A)，第二魔术贴12用于双肩式固定(图5-B)，具体方式在图5中详述。
背板2下部两侧还分别连接有两条腹带7，腹带7上设有魔术贴13，整条腹带7均以魔术贴可粘接材料制成。佩戴时，将魔术贴13粘接于另一条腹带7表面，使两条腹带7在身体前侧相连。
背板2中部设置有可开闭的主袋3(图1中主袋3处于开放状态、图3中处于关闭状态)，主袋3上的开闭和锁定装置为头脚方向的拉链16，主袋3的填充物可由此放入。主袋3的填充物为主气囊9。主气囊9上设置有气嘴15，气嘴15可封闭和开放主气囊9以实现充放气。主气囊9充气后的尺寸和形状与主袋3大体相同。用气囊作为填充物便于携带，可以通过充放气来调节侧卧角度，还可利用其容易变形的优势来达成翻身动作。
本实施例可以通过控制主气囊9的饱满程度来调节侧卧角度。同时，在主袋3上设置了调节拉链17，使主袋3与不同饱满程度的主气囊9相匹配。调节拉链17的左右两半固定于主袋3外表面并保持一定的距离。通过开闭拉链17，可以调节主袋3的表面积，进而调节主袋3的尺寸和/或形状。
主袋3下方设有一个与之连通的副袋4，主袋3和副袋4连通处为连接部24。副袋4可以为背包1提供翻身功能，具体过程在图6和图7中详述。副袋4设有调节拉链18来调节其大小。调节拉链18的左右两半拉链均固定于副袋4外表面并保持一定的距离。通过开闭拉链18，可以调节副袋4的表面积，进而调节副袋4的大小，从而间接调控主气囊9的最小隆起高度21(见图7)。
图4展示了第一个实施例中背包1辅助侧卧的情况。肩带5、拉带6和腹带7将背包1固定在使用者背部。在双肩和腰部三点固定的情况下，背包1很牢固，不会绕躯干发生转动。同时，肩带5、拉带6和腹带7分散了固定背包1所带来的束缚力。主气囊9撑起主袋3，使背包1在使用者背部隆起，支撑使用者背部，辅助其保持侧卧，同时阻碍使用者转为仰卧。通过调控主气囊9的饱满度，同时调整主袋3的调节拉链17，可以调整背包1的大小，从而调节侧卧角度。
图5展示了第一个实施例中背包1的两种固定方式。拉带6和腹带7整体为魔术贴可粘接材料。图5-A展示了背包1的胸部交叉式固定。此时两条拉带6分别自下而上穿过身体异侧肩带5前段的环10，折回后用第一魔术贴11粘在其 所在拉带6的表面。由于胸部交叉式固定耗用的拉带6较长，因此第一魔术贴11的位置刚好与之匹配。此时第二魔术贴12处于尚未穿过环10或刚刚穿过环10的位置，可将其就地粘在拉带6的表面协助固定。从图5-A中看到，魔术贴11的可变粘接位置介于环10和其所在拉带6与背板2的连接处之间。如果使用较短的肩带5，优选为15cm，则拉带6的可调范围可适用于所有身材的使用者。
图5-B展示了背包1的双肩式固定，此时两条拉带6分别自下而上穿过身体同侧肩带5前段的环10，折回后用第二魔术贴12粘在其所在拉带6的表面。由于双肩式固定耗用的拉带6较短，因此第二魔术贴12的位置刚好与之匹配。拉带6前段的冗余部分可以用第一魔术贴11固定在肩带5、拉带6或腹带7上，以避免散乱。魔术贴12的可变粘接位置介于环10和其所在拉带6与背板2的连接处之间，如果使用较短的肩带5，优选为15cm，则拉带6的可调范围可适用于所有身材的使用者。
本实施例中的两条腹带7，其材质均为魔术贴可粘接材料，其中一条腹带7上设有魔术贴13。佩戴时，将魔术贴13粘接于另一条腹带7表面，使两条腹带7在身体前侧相连，实现背包1的腰腹部固定。
图6和图7介绍了本实施例中背包1的翻身功能。在图6-A和图7-A中，使用者保持侧卧，尚未开始翻身，主气囊9未进入副袋4。接下来，使用者开始翻身，主气囊9受到的压力增大，其弹性外壁膨胀并逐步进入副袋4，使主袋3和主气囊9的隆起高度下降。在图6-B和图7-B中，使用者转至仰卧状态，主气囊9充满副袋4，此时主袋3和主气囊9被压缩至最小隆起高度21。但使用者在仰卧状态下不能达成稳定平衡状态，根据其翻身意愿继续向另一侧翻转，开始进入侧卧状态。在图7-C中，使用者恢复另一侧的侧卧状态，主气囊9受到的压力减小并弹性收缩，侧卧角度增大，达成理想侧卧角度和稳定平衡状态。
在此实施例中，主气囊9的全部表面可以为弹性材料，也可以只在副袋4处为弹性材料。通过选择合适的弹性材料，可以调控主气囊9发生形变的压力阈值，以适应不同的使用者。
在此实施例中，调整副袋4的大小可以调控主袋3和主气囊9在受压状态下的最小隆起高度21，以适应不同的使用者。一方面让使用者能够克服这个障碍完成翻身，另一方面让使用者无法在仰卧状态下达成稳定平衡状态，必须转入侧 卧状态。
图8和图9为本发明的第二个实施例，其总体结构与第一个实施例相似。本实施例的特殊部分在于，主气囊9在主袋3与副袋4的连通处，其外壁通过连接阀20连通一个弹性副气囊19。图8-A中，使用者保持侧卧，此时副气囊19处于收缩状态。图8-B中，使用者在翻身过程中转至仰卧状态，此时主气囊9受压使气体进入副气囊19，副气囊19膨胀并充满副袋4，使主袋3和主气囊9变得扁平。通过选择合适的弹性材料，可以调控副气囊19发生形变的压力阈值，以适应不同的使用者。
在此实施例中，连接阀20由阀框22和阀芯23两部分组成。阀框22固定在主气囊9上，阀芯23固定在副气囊19上，阀框22和阀芯23可通过螺纹、旋转卡扣、插接等方式密封连接。所述阀框22和阀芯23的相互套叠插入关系在其他实施例中可以互换。通过所述连接阀20，可以替换使用不同弹性的副气囊19。图9-A为阀框22与阀芯23连接前的侧视图。图9-B为阀框22与阀芯23连接后的侧视图。图9-C为阀框22与阀芯23连接后的俯视图。如图9-D所示，如果不需要副气囊19，可将阀芯23变为盖子，完全封住连接阀20。另外，随着新需求的开发，后续可考虑在阀芯23内部设置气流控制装置或其他智能装置，以提升背包1的功能。
图10为本发明的第三个实施例，其总体结构与第一个实施例相似。本实施例的特殊部分在于，主袋3与副袋4以及连接部24的横截面大致相同，此时主袋3和副袋4已经融为一体。图10-A中，使用者保持侧卧，此时主气囊9占据了主袋3的空间，未进入副袋4的区域。图10-B中，使用者在翻身过程中转至仰卧状态时，主气囊9受压弹性膨胀，充满副袋4的空间，同时主袋3和主气囊9变得扁平，让使用者完成翻身。在此实施例中，主气囊9在侧卧状态下有可能在主袋3和副袋4相融合的空间内沿头脚方向发生位移，但只要控制在合理范围内，并不影响使用者的侧卧姿态，因为主气囊9并未发生沿背部垂直于脊柱方向的位移；也不会影响翻身功能，因为在侧卧状态下，主袋3和副袋4相融合的空间内，未被主气囊填充的空间没有发生变化。
图11和图12为本发明的第四个实施例。此实施例的主袋3、副袋4、主气囊9、及其附属装置的结构与第一实施例相似。本实施例的特殊部分在于，佩戴 时，主袋3位于腰臀部，副袋4位于臀部和大腿后侧。与之相适应，背板2的形状和尺寸有所调整。在固定方式上，本实施例没有使用肩带5和拉带6，而是采用了腹带7和腿带8相配合的模式。佩戴时，腹带7的固定方式与第一个实施例相同，腿带8一端固定在背板2下部，另一端自后向前穿过使用者裆部，再绕过大腿，最终以魔术贴14连接于腹带7位于身体侧面的外表面，实现绕腿式固定。本实施例为双腿和腰部三点式固定，同样可以避免背包1绕躯干旋转，亦可有效分散束缚力。另外，副袋4设置于臀部以下，更有利于翻身。因为在翻身的过程中，双腿通常略有弯曲，此时大腿对副袋4的压力较小，副袋4在转至仰卧状态时比第一实施例更加鼓胀，可以更有效的降低主袋3和主气囊9的最小隆起高度。本实施例具有易于翻身、佩戴舒适、方便拆卸等优点，尤其适合孕妇使用。
最后所应说明的是，以上实施例仅用以说明本发明的技术方案而非限制。尽管参照实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，对本发明的技术方案进行修改或者等同替换，都不脱离本发明技术方案的精神和范围，其均应涵盖在本发明的权利要求范围当中。
