Description

预防褥疮医疗床 技术领域
本发明主要涉及到防止发生褥疮的理疗床，更加具体地讲此发明的自动床，能够自动识别患者躺着的位置和躺姿，自动的把患者向右或向左侧翻，也可以把翻趴姿势的患者自动识别后翻回到正躺姿势，不但如此还能够自动识别不知不觉到床边的患者之后，自动的送回到床的中间位置，起到防止滚落床的作用。而且平时还可以当做吊床把患者吊躺，即可防止褥疮的产生，还能带来最舒服的躺姿。可全自动更换尿不湿，儿童可用作摇篮床使用，成人可用作吊床使用。
背景技术
通常肢体活动困难的患者，尤其是老年人患者主要在医院，养老院或者在家长期卧床生活。最近已进入老龄化时代，需要卧床休养的患者在急剧增加。长期卧床时与床面长时间接触的局部受到床面的长期压迫，导致血液循环不畅该部位的细胞坏死，导致产生了褥疮。
褥疮主要产生在患者的背部，臀部，胯骨。头部等部位。要防止褥疮的产生，护理员得经常为患着翻动身体，但每天整夜护理员为患者翻动是很难办到的。
为了改善这一点，许多现有文件(韩国专利注册号10-1731967)中是通过折翻前部，中部，后部床板来改变患者的姿势。然而，上述常规床仅能抬起患者的上身或抬起腿。只能进行抬起操作，不能将患者侧翻身，无法有效防止背部和臀部皮肤的压迫导致褥疮的产生。
为了改善这种常规床的问题，有一种床(韩国专利注册号10-1895054)将床板以床的长度方向在中间左右分开，将左右倾斜床板，往床里侧方向翻转的方式把患者侧翻身，以达到防止褥疮的产生。但这种床在翻转侧翻床板时，经常把患者滑到床的里边而不是侧翻身，还要通过护理员的帮助才能达到侧翻身的目的。
还有这种结构的床，患者正好在靠近床中间位置而且是正顺着床的长 度方向时，翻动床板能把患者安全的侧翻身，否则患者不在床中央时，直接翻动床板会把患者滚落到床下，即时翻转了也不是患者所需的姿态，故这种结构的床只能在护理人员的监护下才能使用，否则会有安全隐患。
发明内容
本发明是为了解决上述现有技术上所存在问题而研发，首先自动判断患者在床上的位置和躺姿，然后自动向右或向左安全的进行侧翻身动作，既能调整患者的躺姿，以达到防止发生褥疮的目的。

根据本发明，上述床罩两端分别与上述卷帘器的卷筒联接，卷筒是由电机轴联接，随着电机的正反转来实现床罩的松展与收紧动作，但上述电 机的正反转是随工作杆的左右移动与升降而联动的。
根据本发明，上述左右移动机构是由，左右移动电机减速机齿轮1，啮合固定在床架下端上的主横梁的齿条1，随电机的正反转来实现左右移动的目的。工作杆的升降是由升降电机减速机齿轮2啮合固定在左右移动机构上的升降机构齿条2，随电机的正反转来实现升降目的。
根据本发明，上述支持左右移动机构与之上固定的升降机构的主横梁可以是固定在床中间的单梁结构，也可以是床的前后固定的双梁结构。
根据本发明，采用单梁结构时，左右移动机构各一套(共2套)，升降机构为左右各一套(共2套)，它们是根据需要各自独立运动。
根据本发明，采用双梁机构时左右移动机构为前后左右各一套(共4套)，升降机构为左右前后各一套(共4套)，它们是根据需要各自独立运动。
根据本发明，采用双梁机构时左右移动机构为前后左右各一套，升降机构为左右前后各一套，处于同一侧的升降机构用联轴器连接后可用一套电机减速机机构带动，这时同一侧的升降动作是同步进行。
根据本发明，采用升降杆与齿条结合一体的结构，升降电机固定在升降机构的上端第2齿轮啮合齿条式升降杆做上下移动。
根据本发明，上述感应部件1是感应工作杆左右移动时所受到的侧向力来控制工作杆的左右移动。上述感应部件2是感应工作杆上下移动时所受到的向下的力来控制工作杆的上下移动。
也可以把感应部件1和感应部件2合并，用一套安装在升降机构底部的重力传感器来取代，控制上述左右移动机构和升降机构的运动。
根据本发明，在床垫下边安装的金属探测器检测患者服正面的金属纽扣或金属条来判断患者是正躺或趴脯状态，以便自动调整患者姿态。
根据本发明，这一识别患者趴脯状态的传感器，也可以用安装在床头上的人脸识别机构来判断患者是不是在趴脯状态。
根据本发明，工作杆外层采用橡胶或硅胶等弹性体材料，与患者身体接触时防止冲击现象。
根据本发明，上述床罩上面以粘拉锁方式粘上患者用尿不湿等样的卫生纸(布)。
根据本发明，被子的4个角是用弹性带子与床架4个角的挂钩连着，所以患者随工作杆做各种动作时，盖在患者身上的被子也是随患者抬高与下落跟着升落，不会打卷始终保持被子盖着患者身体的状态。
根据本发明，固定在床架下的枕头梁之上的电推杆与之连接的枕头是随着工作杆的升而升降，这时电推杆下端的称重传感器探测患者的头部重量，使得患者的头是始终是处于枕着头部的状态。

本发明防褥疮理疗床，从图1至图8示意图中看出，患者是用床罩(5)裹着向左或向右侧翻身或平躺动作的。这些动作是靠:床架(10)，床罩卷桶(20)，主大梁(35)，左右移动机构(30)(30’)升降机构(40)(40’)及传感器机构(50)组成的机械机构来实现的。
上述机构中，床架(10)上面是床板(11)，靠支持床架的支腿(12)确定高度。
上述床罩(5)的两头连接在固定到床架两边的卷帘器(21)(21’)的卷筒(20)上，保持绷紧状态。
这时卷帘器(21)(21’)是靠与卷帘器电机(22)轴连接的卷筒(20)的正反转来实现与之连接的床罩(5)的松展与绷紧状态的，但这一动作是随工作杆(45)的升降与左右移动而联动。
上述左右移动机构(30)(30’)是装配在固定到床架下端的主横梁(35)的左，右两侧，上述升降机构(40)(40’)是装配到左右移动机构(30)(30’)之上，使之与升降机构(40)(40’)的升降杆(44)(44’)垂直浮动连接的工作杆(45)(45’)在床罩下，顺着床的长度方向上，左、右、升、降等独立运动，随着工作杆(45)(45’)的动作，床罩(5)裹卷患者自动完成，向右或向左侧翻、平移、平躺、吊躺等动作。
在这里，上述左右移动机构(30)(30’)是靠第1齿轮(32)啮合安装在床架下边的主横梁(35)上的第1齿条(31)通过行走电机(33)的正反转来实现左右移动。上述升降机构(40)(40’)是靠第2齿轮(42)啮合安装在左右移动机构(30)(30’)之上的升降机构(40)(40’)的第2齿条(41)(41’)随升降电机(43)(43’)的正反转来实现升降杆(44)(44’)升降的。
这时上述左右移动机构(30)(30’)是顺着安装在主大梁(35)上的导轨(38)做左右移动动作。升降杆(44)是顺着安装在升降机构(40)(40’)上的导轨(49)做上下运动。(图15中升降杆(44)和第2齿条(41)是结合一起的同一体)
本发明中，上述左右移动机构(30)(30’)和升降机构(40)(40’)可安装在如图1单主大梁(35)上，左右上下移动，也可以安装在如图10双大梁(35)(35’)上，各自左右上下移动。
本发明中上述升降机构(40)(40’)可采用如图13升降减速机机构，升降杆与丝母(47b)结合，随丝杆(47a)的旋转而上下移动。也可采用如图14电推缸机构，工作杆(45)与推杆(48a)浮动连接，在推缸(48)的作用下，进行上下运动。
如图15，采用升降杆(44)与齿条(41)结合一体的结构，升降电机(43)固定在升降机构(40)(40’)的上端，第2齿轮(42)啮合齿条式升降杆做上下移动，工作杆(45)(45’)与齿条式升降杆浮动连接。
参照图11至图12中，左右移动机构(30)(30’)是在双主梁机构上独立运动，升降机构(40)(40’)是在双主梁机构上，同一侧的升降机构用联轴器(46)连接，采用一套电机机构随电机的正反转时，第2齿轮(42)(42’)啮合第2齿条(41)(41’)带动同一侧的两个升降杆 同步运动。
上述，感应机构(50)的第1压力传感器(51)和第2重力传感器(55)分别控制，左右移动机构(30)(30’)和升降机构(40)(40’)的运动。
也可以把第1压力传感器(51)和第2重力传感器(55)合并，用一套安装在升降机构(40)(40’)底部的第3重力传感器(62)来取代，控制上述左右移动机构(30)(30’)和升降机构(40)(40’)的运动。
这时，感应方式1：第1压力传感器(51)，安装在升降机构的上部靠床边位置，通过感应工作杆(45)(45’)左右移动时，因碰触患者身体所产生的压力变化来控制左右移动机构(30)(30’)的运动。第2重力传感器(55)安装在左右移动机构(30)(30’)的下端位置，通过感应工作杆(45)(45’)所受的的重力的变化来控制升降机构(40)(40’)的运动。
工作杆(45)(45’)是在金属杆(45a)(45’a)上包裹上橡胶或硅胶等弹性材料层(45b)(45b’)来组成，与患者接触时是弹性接触，防止患者受到冲击。
如图16在床罩(5)上面用粘拉锁等的方式，粘上专用卫生垫等辅助垫(6)及容易交换又能保持床罩的清洁卫生，采用帘式专用卫生垫时可全自动更换卫生垫。
之外，在床板下部安装磁感应器(金属探测器)(15)感应到患者服的金属纽扣或患者服正面所粘附的软金属带时，即可确定患者是处于趴脯姿势这时立刻自动进行翻体动作。
也可以通过安装在床头上的人脸识别机构(59)来监控患者的趴脯姿势，实现上述翻体动作。
再者如图15所示，把床架上的平铺板(11)分成上下块(11a)(11b)，通过电推缸(13)(13’)做上下倾斜动作。
本发明中，上述的一切动作即左右移动机构(30)(30’)及升降机构(40)(40’)可以用遥控器操作，也可以结合安装在床头上的摄像头(60)，用智能手机远程观察及操作。
安装在升降机构(40)(40’)底部的第3重力传感器(62)能够实 时监控患者的体重，配合感应机构(50)为左右移动机构(30)(30’)和升降机构(40)(40’)的动作提供精准数据。还能为治疗患者的病情实时提供患者体重的变化。
安装在支腿(12)下边的4个脚轮(18)为本发明床的移动，提供了轻便的操作。
再者本发明中，如图21、图22所示，安装在固定到床架上的枕头支架(70)之上的电推杆(71)(71’)随着工作杆(45)(45’)升降而联动，与之固定到电推杆(71)(7’1)之上的枕头(73)跟着上下移动。这时安装在电推杆(71)(71’)下边的重力传感器(69)(69’)感应患者头部的重力，始终保持头部枕着枕头的状态。
再者本发明中，如图24所示，枕头机构(79)安装在床板(11)的下部，床板(11)在电推杆(13)(13')的推动下翻转时，枕头机构(79)跟着同时翻转，这时也可以当做背靠来使用。
与上述不同，如图23，24a所示，枕头机构(79)不是用电推杆的方式驱动，而是在电机(71a)轴上固定支臂(70a)与之连接重力传感器2(69a)，随着电机的正反转，联动着的枕头轴(72)与枕头(73)做上下移动，这时重力传感器2(69a)感应头部的重力，使之始终维持头部枕着枕头的姿势。
上述床板(11)做倾斜时如图28、图29床罩卷桶(20)(20’)分为(20a)(20a’)之间用万向节连接，这时如图24床罩卷桶(20a)(20a’)随着倾斜，床罩(5)也是分成2张一起倾斜。
床罩下边安装有冷热风机，随室温的变化为患者送给舒适的风。
根据本发明，如图31在本发明床长度方向的一侧的床腿(12)上安装卷帘器升降机构(100)，齿轮(104)啮合齿条(103)随电机(105)的正反转驱动卷帘器做升降运动，卷帘器臂(106)随着做伸展收缩动作，把患者从床上抬到床下，也可把患者抬到床上。
根据本发明，如图32在本发明床长度方向的一侧的床腿(12)上安装卷帘器升降机构(100)，与电机(105)驱动的轴上的轮(111，111’)与上端滑轮(109，109’)用钢丝绳结合随电机(105)的正反转，带动卷帘器做升降运动，卷帘器臂(106)随着做伸展收缩动作，把患者从床 上抬到床下，也可把患者抬到床上。
上述卷帘器升降机构(100)根据需要可以安装在床的右侧也可以安装在床的左侧。
各个部件在本发明中的功能及作用：
首先，本发明的理疗床，判断出患者的位置及躺姿之后，用床罩裹着患者往左侧或往右侧按所设定的最佳周期循环往复的翻动，从而防止褥疮的产生。
具体说明如下：见图6、图7所示，首先停靠在床架(10)两边的工作杆(45)随左右移动机构(30)(30')往床的中央方向移动。
这个动作是由左右移动电机(33)的旋转，带动电机(33)轴上的第1齿轮(32)啮合第1齿条(31)进行移动。
这时左右工作杆(45)随左右移动机构(30)(30’)往床的中央移动，当工作杆(45)碰触到患者时，所发生的阻力通过第1压力传感器(51){或者综合重量传感器(62)}传给传感机构(50)控制移动机构(30)(30’)的运动与停止。
也就是说，工作杆(45)准确的找到患者的位置后，停止在患者两侧的位置。
这时要把患者往右侧翻动时，如图6所示，升降机构(40)(40’)上升，工作杆(45)把床罩(5)抬高到一定高度，床罩(5)把患者裹上。
这时升降机构(40)随升降电机(43)的转动，第2齿轮(42)啮合第2齿条(41)向上移动。
这个状态下患者左侧的工作杆(45)，即继续上升，又往床的中央方向移动，右侧的工作杆(45)即一面下降又往床边移动。
这时随工作杆(45)(45’)同时工作的是，连接床罩(5)的两边卷帘器(21)(21’)，一边的是放展，另一边的是收紧，使床罩(5)始终保持绷紧状态。也就是说左侧的工作杆(45)上升时，左侧的卷帘器(21)放展床罩，右侧的卷帘器(21’)收紧床罩。
如此用床罩(5)裹着患者往右侧方向翻转，这时施加在第1压力传感器(51)和第2重力传感器(55){或者综合重量传感器(62)}的压力 逐渐减小，患者就往右侧翻转过来了随即移动机构(40)也就停止运动。
整个翻转过程中始终是用床罩(5)裹着患者翻转的，所以不会把患者翻落床，而且安全的把患者侧翻转过来。
反过来，要把患者往左侧翻转时，如图7所示，升降机构(40)(40’)上升，工作杆(45)把床罩(5)抬高到一定高度，床罩(5)把患者裹上。
这个状态下患者右侧的工作杆(45)，即继续上升，又往床的中央方向移动，左侧的工作杆(45)即一面下降又往床边移动。
这时随工作杆(45)(45’)同时工作的是，连接床罩(5)的两边卷帘器(21)(21’)一边的是放展，另一边的是收紧，使床罩(5)始终保持绷紧状态。
如此用床罩(5)裹着患者往左侧方向翻转，这时施加在第1压力传感器(51)和第2重力传感器(55){或者综合重量传感器(62)}的压力逐渐减小，随即工作杆(45)停止运动。这样患者就往左侧翻转过来了。整个翻转过程中始终是用床罩(5)裹着患者翻转的，所以不会把患者翻落床，而且安全的把患者侧翻转过来。
再者，如图8所示，把患者向右侧翻转过程中，意外出现翻扣现象时床垫下边的磁感应器(15)感应患者服的金属纽扣或金属软带，确认患者的翻扣，这时右侧的工作杆移动到患者身边，第一感应机构(51){或者综合重量传感器(62)}感应确认后工作杆(45)停止平移，做上升运动上升到如图30与左侧工作杆相同高度即刻停止，这时右侧卷帘器(21)收紧床罩，左侧卷帘器(21')放展床罩，把患者旋转180度，根据卷帘器旋转角度来确定角度，停止后工作杆(45)(45')慢慢下降移动到床边，两边卷帘器收紧床罩(5)处于绷紧状态。
再者，与图8相反：把患者向右侧翻转过程中，意外出现翻扣现象时，是上述动作的反向动作。
再者，患者在床上无意识的出现翻扣现象时，床垫下边的磁感应器(15)感应患者服的金属纽扣或金属软带，确认患者的翻扣，这时左，右侧的工作杆移动到患者身边，第一感应机构(51){或者综合重量传感器(62)}感应确认后，工作杆(45)(45’)停止平移，做上升运动上升 到如图30左右工作杆同时上升到一定高度即刻停止，之后患者往床中心移动的同时，一侧卷帘器(21)收紧床罩，另一侧卷帘器(21’)放展床罩，把患者旋转180度，根据卷帘器旋转角度来确定角度，停止后工作杆(45)(45’)慢慢下降移动到床边，两边卷帘器收紧床罩(5)处于绷紧状态。
与上述相反，有特殊患者是不能正面躺着，只能要处于趴脯状态，这时患者服正面粘着的软金属带粘在患者服背面即可(这时患者服不能用金属纽扣)。这时上述翻转动作是自动反向动作，让患者只能处于趴脯姿势或侧躺姿势。
再者，患者非本意的挪动到床边有落床危险时，会压到工作杆(45)这时第2传感器(52){或者综合重量传感器(62)}感应到患者处于非正常位置，这时按前述方式，把患者移动到床的中央位置。
再者，工作杆(45)(45’)是在金属杆(45a)(45a’)上包裹上，橡胶或硅胶等弹性材料层(45b)(45b’)来组成，与患者接触时是弹性接触，防止患者受到冲击。还能如图26和图27所示患者处于侧向躺姿时，固定到升降机构(40)(40’)上的按摩大梁(80)(80’)之上的按摩机构(91)(91’)，能给患者进行简单的背部按摩。
本发明中，按摩力度调节器(81)可调节背部按摩力度。
再者，在床罩(5)上面用粘拉锁等的方式，粘上专用卫生垫等辅助垫(6)及容易交换又能保持床罩的清洁卫生，采用帘式专用卫生垫时，与床罩一起卷到卷筒上之后如图30这时左，右两侧的工作杆移动到患者身边，第一感应机构(51){或者综合重量传感器(62)}感应确认后，工作杆(45)(45’)停止平移，上升到一定高度即刻停止，之后患者往床中心移动的同时，一侧卷帘器(21)收紧床罩，另一侧卷帘器(21’)放展床罩，把患者旋转360度，根据卷帘器旋转角度来确定角度，停止后工作杆(45)(45’)慢慢下降移动到床边，两边卷帘器收紧床罩(5)处于绷紧状态，完成全自动更换卫生垫的动作。这时(115)热缩膜随卷帘桶旋转覆盖到卫生垫的上边，保证了卷帘桶的清洁及更换时的清洁与方便。
再者，本发明用作儿童摇篮床时如图30，这时左，右两侧的工作杆 移动到往床中心移动一定距离，上升到一定高度即刻停止，一侧卷帘器(21)收紧床罩，另一侧卷帘器(21’)放展床罩，此动作交替进行，根据频率和摆渡幅度的调整，起到了摇床的功能。
之外：本发明中，升降机构(40)(40’)可以采用如图13和图14，图15的机构来实现升降功能。如图13，采用升降减速机机构，升降杆与丝母(47b)结合，随丝杆(47a)的旋转而上下移动。也可以采用如图14，采用电推缸机构，工作杆(45)与推杆(48a)浮动连接，在推缸(48)的作用下，进行上下运动。
如图15，采用升降杆与齿条结合一体的结构，升降电机(43)固定在升降机构的上端第2齿轮(42)啮合齿条式升降杆做上下移动，工作杆(45)(45’)与齿条式升降杆浮动连接。
参照图9至图12，上述左右移动机构(30)(30’)及升降机构(40)(40’)可以用其他方式驱动。图9及图10中，左右移动机构(30)(30’)及升降机构(40)(40’)是在双主梁机构上各自做独立运动。(这种方式对非均匀状态身材的患者尤为适应)参照图11至图12中，左右移动机构(30)(30’)是在双主梁机构上独立运动，升降机构(40)(40’)是在双主梁机构上，同一侧的升降机构用联轴器(46)连接，采用一套电机机构随电机的正反转时，第2齿轮(42)(42’)啮合第2齿条(41)(41’)带动同一侧的两个升降杆同步运动。
本发明的床，不但能够判断患者的位置、躺姿等之后用床罩(5)裹卷患者，按设定程序及周期自动循环的做：向右侧翻、平躺、向左侧翻、平躺、吊躺等动作，还能防止患者落床，从而有效的防止褥疮的发生，还能给患者带来安全与舒适的快感。
根据本发明，如图17患者要吊躺时，左右卷帘器放展一定长度的床罩，左右工作杆(45)(45’)同时向床中心移动一端距离停止，之后上升，这时通过第2传感器(55){或者综合重量传感器(62)}所受到的设定压力限制停止上升，患者处于舒服的吊躺姿势。
根据本发明，如图21、图22所示，安装到枕头支架(70)上的电推杆(71)(71’)与之上固定的枕头(73)随着工作杆(45)(45’)的上下移动，而同步上下移动。
这时安装在电推杆(71)(71’)下端的重力传感器(69)感应头部的重力，使枕头始终处于枕着头部的状态。
与上述不同，如图24枕头机构(79)安装在活动床板(11)的下边，活动床板(11)在电推杆(13)(13’)的作用下做倾斜动作时，也同时倾斜这时也可作为背靠来使用。
上述床板(11)做倾斜时如图28、图29床罩卷桶(20)(20’)分为(20a)(20a’)之间用万向节连接，这时如图24床罩卷桶(20a)(20a')随着倾斜，床罩(5)也是分成2张一起倾斜。
与上述不同，如图23，24a枕头机构(79)的驱动不是以电推杆的方式，而是用电机(71a)的正反转，通过支臂(70a)和与之连接的重力传感器(69a)驱动枕头杆(72)和枕头(73)做上下运动，这时重力传感器(69a)感应头部的重力，使枕头始终处于枕着头部的状态。
根据本发明，理疗床自动完成上述防褥疮动作时，见图20盖在患者身上的被子(66)随患者抬高与下落跟着升落。但被子(66)的4个角是用弹性带子(67)与床架(10)4个角的挂钩连着所以不与患者身体一起移动，也不会打卷。
床罩下边安装有冷热风机，随室温的变化为患者送给舒适的风。
根据本发明，如图31在本发明床长度方向的一侧的床腿(12)上安装卷帘器升降机构(100)，齿轮(104)啮合齿条(103)随电机(105)的正反转驱动卷帘器做升降运动，卷帘器臂(106)随着做伸展收缩动作，把患者从床上抬到床下，也可把患者抬到床上。
根据本发明，如图32与上述驱动方式不同，在床的长度方向，同一侧的床腿(12)上安装卷帘器升降机构(100)，2个主动滑轮(111，111’)之间用传动轴连接，钢丝绳(110，110’)的一头连接到主动滑轮上，通过上端滑轮(109，109’)另一头连接到卷帘器移动臂(106)(106’)上，随电机(105)正反转，带动卷帘器做升降运动，卷帘器臂(106)随着做伸展收缩动作，把患者从床上抬到床下，也可把患者抬到床上。
在本发明中，患者从床上下到地面的具体方式如图33a至图33e：要从床上图33a下到地面时如图33b右侧卷帘器放展床罩的同时，移动臂(106)(106’)即上升又向右侧倾斜，如图33c移动臂(106)(106’) 上升到与床面同一高度水平位置时，如图33d右侧卷帘器收紧床罩，左侧卷帘器放展床罩把患者移送到床侧面，如图33e这时靠电机的旋转患者就可以下到地面(下降高度自由确定)这时就可以做冲洗(床罩是透气的网格状，冲洗水直接漏到下面容器里)等其他事宜。
本发明中，患者要从地面上到床上面时，做上述动作的反向动作即可实现。
上述卷帘器升降机构(100)，可根据需要或安装在床的右侧也可以安装在床的左侧。
上述本发明医疗床的所有动作，在停电状况下靠本医疗床自带充电电池组正常工作。为防止充电电池组自爆现象为患者带来2次伤害，电池组分数块内藏于床支腿(12)内部。
本说明书中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的方法及其核心思想；同时，对于本领域的一般技术人员，依据本发明的思想，在具体实施方式及应用范围上均会有改变之处。综上所述，本说明书内容不应理解为对本发明的限制。
