Description

可呈坐姿便溺的护理床 技术领域
本发明是有关一种可呈坐姿便溺的护理床，尤指一种以杠杆操作原理，具有使用省力特性的装置。
背景技术
随着中国台湾人口逐渐高龄化，许多老人疾病亦随之增加，而许多行动不便、中风、脑部病变、中枢神经受损及瘫痪或长期卧病在床的人，都缺乏行动能力，必须长期躺在护理床，因此病患的移动，需仰赖家属、看护以较大力量来进行辅助，亦造成家属、看护及病患的不便，此外，病患于家属或看护人辅助解决排泄物或洗澡的问题，使病患感觉失去尊严，并给予病患极大的心理负担。
图1A及图1B所示，是CN101912332A所揭露的一种『自动护理床』，其包括：床体1，设于该床体上的一背部活动板131、中间床板132、腿部活动板133，及一设于中间床板132的护理孔132a；为了要可供病人直接在病床上进行排便的动作，该背部活动板131及腿部活动板133的底部必须分别装设一驱动件131a、133a，将其顶升成图1B所示的状态。但查，现有护理床所使用的驱动件131a、133a大都是气压缸直接驱动的方式，但这种驱动件131a、133a设在床体1下方，以直接驱动的方式来推顶背部活动板131及腿部活动板133，非常费力，所以制动能力不能太小，如此一来，不仅耗电，且驱动件133a设在腿部活动板133的底部，致使腿部活动板133只能向上顶升而无法向下沉降，因此，图1B所示的使用型态，病人以该护理孔132a进行排泄时，腿部须举高，事实上这种姿势并不是很适当及舒适，尚有改善空间。
本发明人有鉴于现有病床的缺失，期能提供病人一实用的护理床省力型传动装置，为本发明所欲解决的课题。

图11是本发明的一使用状态参考立体图，其可在护栏108上装设一用餐盘109，而不会影响到本发明的使用。图12所示，显示病人呈坐姿的示意图，本发明借由上述技 术特征，构成一可供病人直接在病床上成坐姿，进行排便的动作。
本发明借由上述构成，其使用上具有如下的功效，兹说明如后：
首先，本发明屏除传统病床或护理床是以气压缸直接驱动的方式，因为以直接驱动的方式来推顶背部活动板131及腿部活动板133，非常费力且耗电，且驱动件133a设在腿部活动板133的底部，致使腿部活动板133只能向上顶升而无法向下沉降，因此，图1B所示的使用型态，病人以该护理孔132a进行排泄时，腿部须举高，事实上这种姿势并不是很适当及舒适。反观本发明是利用杠杆(lever)操作原理，能够将输入力放大，给出较大的输出力，杠杆的机械利益是输出力与输入力的比率，因此具有「杠杆作用」功能。是以，本发明仅需用手转动该第一手摇驱柄43，即可以该第一动力输出轴41来带动该传动机构50，再由该传动机构50分别驱动该第一推升杆60及该第二推升杆70，该第一推升杆60，可以带动该背部活动架20呈平放状态或掀起一倾斜角度；该第二推升杆70，可以同步带动该腿部活动架30平放状态或向下沉降，这种杠杆原理的传动方式，具有使用省力的特性，以达到使用方便及节省能源的功效。
再者，本发明可以利用该控制机构40的第一离合器46，选择是要以手动操作该第一手摇驱柄43，或是以该马达44来驱动该第一动力输出轴41来带动该传动机构50。是以，本发明具有手动及电动皆可操作使用的双重功效。
又，本发明可以利用该传动机构50的第二离合装置54，得以控制该第一传动杆51a与第二传动杆51b呈轴向结合连动，或是呈轴向分离状态。亦即，当该第一动力输出轴41带动该传动机构50时，本发明可以选择第二传动杆51b是否要与该第一传动杆51a同步动作，也就是该腿部活动架30是否要与该背部活动架20一起连动。是以，本发明可依病人的需求来控制该传动机构50的动作位置。
是以，将本发明上揭省力型传动装置，使用在护理床上，具有省力的特性，达到使用上的方便性、节省能源及舒适性，进而可供病人直接以坐姿在病床上进行排便的动作，以减低病人的负担，增进病人排便的方便性，具有无需他人协助，达到病人自理的功效。
以上所述，仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，凡是依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
