组合式护理床分为固定床体、 活动靠背和轮椅。
在固定床体上设有活动靠背， 活动靠背通过转轴与固定床体铰接， 由固定 床体支承的驱动机构驱动， 从活动靠背外向床尾的一侧 （平卧人体的臀部位置) 开始设置轮椅， 轮椅包括与固定床体分离的三个矩形平面、 轮椅支架和第二驱 动机构。 所述三个矩形平面比人体平卧时宽度略宽 （约 500 --- 600mm) , 位于人 体平卧时臀部下的为固定平面， 固定平面受轮椅支架支承并固定在轮椅支架 上， 或与轮椅支架上面为一体， 固定平面和第二平面通过第二转轴铰接， 第二 平面和第三平面通过第三转轴铰接； 轮椅支架后部下和轮椅支架前部下设车 轮； 轮椅的第二平面和第三平面的升降由第二驱动机构驱动， 第二驱动机构的 可 缩件与由固定床体支承的主动转轴的第二转臂作活动连接， 与第二驱动机 构的可伸缩件连接的固定件与固定床体作活动固定， 固定件上可设驱动件。 主 动转轴与轮椅支架支承的从动转轴作活动连接， 该活动连接使主动转轴驱动从 动转轴同步转动也可使两轴方便的拆分脱离； 在从动转轴上设有挑臂， 挑臂伸 至第三平面下， 并与第三平面下面作可转动固定； 工作步骤之一： 第二驱动机 构的可伸缩件向前伸出， 推动主动转轴的第二转臂运动， 驱动主动转轴转动， 带动从动转轴和挑臂转动， 挑臂则拉动第三平面下降， 通过第三转轴传动， 驱 动原来与床面相平的第二平面绕第二转轴向下转动， 第三平面相对于第二平面 绕第三转轴向上转动， 最终第三平面搁于轮椅支架上， 主动转轴与从动转轴的 活动连接分离， 轮椅的三个矩形平面、 轮椅支架、 从动转轴和挑臂则与固定床 体脱离， 被护理人被同时移动到轮椅上； 工作步骤之二： 将主动转轴与从动转 轴连接， 第二驱动机构工作， 可伸缩件回缩， 拉动主动转轴的第二转臂， 驱动 主动转轴带动从动转轴和挑臂转动， 挑臂则推动第三平面上升转变为床面， 被 护理人被移动到床上； 随着主动转轴与从动转轴装配高度的不同， 工作步骤应 有所调整。
主动转轴由固定床体支承， 在固定床体上设主动转轴支承架， 在主动转轴 支承架上设轴孔， 主动转轴两端位于轴孔内， 在主动转轴支承架上所设轴孔为 圆形轴孔或竖直方向的平椭圆轴孔， 在主动转轴支承架上设竖直方向的平椭圆 轴孔时， 主动转轴可在平椭圆轴孔内转动并具有在竖直方向上滑动的自由度； 从动转轴是由轮椅支架支承的， 可以在与竖直方向垂直的水平方向上滑动的自 由度， 此两个自由度的结合， 使得主动转轴与从动转轴的活动连接和拆分方便， 不因轮椅支架、 橡胶车轮的形变而连接困难。 主动转轴与从动转轴以插接式的 活动连接较为方便， 主动转轴内设插销， 插销和从动转轴内孔配合， 断面为非 圆形， 如断面为矩形， 椭圆形， 插销手柄从主动转轴的开口中伸出， 插接时对 准主动转轴与从动转轴的的位置， 推动手柄就可使主动转轴与从动转轴活动连 接，' 拉动手柄就可使主动转轴与从动转轴的连接脱离； 插销也可设于从动转轴 内与主动转轴内孔配合。
在轮椅支架后部设轮椅靠背， 轮椅靠背可抽插， 在床面上下升降； 轮椅靠 背为抽拉式时， 轮椅靠背的拉杆套叠于外管内； 在拉杆端头设立抽插防脱位结 构， 在轮椅靠背的拉杆端头设防脱位凸台， 凸台上方圆周的一部分设直角槽， 另一部分设与拉杆外表面平滑过度的斜面， 当拉杆抽出时弹性销卡阻防脱位凸 台使拉杆不向上滑脱， 将靠背把手旋转到工作位置， 弹性销进入直角槽， 拉杆 被弹性销卡阻而不可向上和向下滑， 将靠背把手旋转到可隐藏位置， 弹性销对 着过度的斜面位置， 拉杆可滑入外管内， 隐藏于床面下， 抽插式轮椅靠背固定 拉杆的方法很多， 拉杆箱中拉杆的固定方法就不失为一个极好的技术示例。
在轮椅固定平面两侧设活动扶手。
在轮椅的固定平面下设大小便器托板， 在固定平面上设盖板或固定平面设 盖板和第二平面上设门板， 固定平面和第二平面上大小便器的活动盖板位置相 邻的边框作相应让空。
第二驱动机构的可伸缩件与固定件相连构成能产生直线往复运动的机械装 置， 如电动推杆、 手动推杆、 气缸、 油缸或气弹簧。
手动推杆是由螺杆和内螺纹管配合构成， 前部为可伸缩件， 后部固定件与 固定床体活动固定， 固定件的末端的驱动件为摇把； 电动推杆是由螺杆和内螺 紋管配合构成， 前部为可伸縮件， 后部与固定床体活动固定， 固定件上的驱动 件为电动机。
能产生直线往复运动的机械装置为气缸、 油缸或气弹簧时， 固定件的末端 则不设驱动件。
在轮椅支架后设定位管， 轮椅支架与定位管之间设第四转轴和定位件， 在 定位管与轮椅从动转轴的第三转臂之间设活动连杆， 该活动连杆可以与定位管 及轮椅从动转轴的第三转臂脱离， 轮椅靠背立杆插于定位管中， 转动轮椅靠背， 通过连杆驱动轮椅从动转轴转动， 让挑臂托起第三平面， 轮椅即成为一个可运 动的平床。
轮椅的第三平面上设有一翻板。
本发明的组合式护理床， 可以分离出轮椅， 分离轮椅时让不具有自由行动 的人方便的从病床转移到轮椅上， 这一过程可逆， 该转移过程不但不需要护理 者付出艰苦的劳动， 被护理者也不因被牵动而遭受痛苦， 这样就可方便的将被 护理者移动到室外活动， 到餐厅吃饭， 到浴室洗浴， 也可坐着大小便， 更方便 医疗， 提高生活质量和护理质量。
