具体实施方式
参考图1,本发明提供了包括侧臂延伸件5的救护床1。虽然附图描绘了该侧壁延伸件附接至救护床1,但可以构想任何患者运输装置,例如床、轮椅、担架、折叠式搬运椅等也可以利用该侧臂延伸件。侧臂延伸件5包括患者运输装置接合构件20,该患者运输装置接合构件用来沿着患者运输装置框架(例如床框架2)或者沿着被附接到床框架的支撑框架3的周边与患者运输装置(例如救护床1)的框架2接合。支撑框架3是支撑平台,该支撑平台具有支撑患者的外导轨。侧臂延伸件5典型地附接到支撑框架3的导轨;然而可以构想,该侧臂延伸件也可以附接到床框架2。侧臂延伸件5还包括:可转动的且可枢转的扶手10;以及侧臂运动基座25,该侧臂运动基座将扶手10连接到患者运输装置接合构件20。
如图9的实施例中示出地,患者运输装置联接构件20可以包括静止区段22,该静止区段经由带轮廓表面21联接到支撑框架3,并且患者运输装置联接构件也包括可转动区段24,该可转动区段附接到侧臂运动基座25并可随其转动。参考图7的实施例,患者运输装置接合构件20可以包括带轮廓表面21,该带轮廓表面适于经卡扣附接到支撑框架3周边上的侧杆上。各种联接机构被构想用作患者运输装置接合构件,例如上述卡扣配合件。另外的紧固件(未示出)可以用于确保侧延伸件被牢牢地紧固至侧杆或侧导轨。参考图1,患者运输装置接合构件20典型地联接到与支撑框架3的靠背相邻的一个或更多个侧导轨;然而,本文也构想到其它的位置。
如下文将详细描述地,侧臂延伸件5包括允许侧臂延伸件5转动且以垂直于支撑框架3的周边的方式向外枢转的部件。在图1中示出的一种构造中,当靠背升高到竖立位置时,扶手10可以转动,使得床1的下部躯干部分4沿水平方向平行于扶手10。或者,当在如图2-图4中描绘的非竖立位置中(即,在侧臂延伸件基本不使用中的示例性位置中)时,侧臂延伸件5可以转动以使得扶手10的端部靠近支撑框架3的头部区段定位(见图2),或者转动以使得扶手10的端部靠近支撑框架3的下部躯干区段4定位(见图3和图4)。此外,如图5中所示,扶手10可以如示出地向外枢转或摆动。这种向外枢转运动会有利于体型大或肥胖的患者,这种患者在扶手处于未枢转位置中时会难以合身于扶手10之间的空间中。
参考图6和图9,侧臂运动基座25包括:转动机构(例如,棘轮机构37),该转动机构被构造用来使扶手10转动;和摆动机构,该摆动机构被构造用来使扶手背离床框架周边的周边向外枢转。转动机构允许直至360°的转动自由度,或者在特定实施例中,该转动机构允许直至180°的转动自由度。摆动机构允许直到90°的枢转运动,或者在特定实施例中允许相对于侧臂运动基座直至25°的转动。
在一个实施例中,转动机构是如图8和图9中描绘的棘轮装置。参考图8和图9,侧臂运动基座25的棘轮机构37包括至少一个突出部38,该至少一个突出部插入到患者运输装置联接构件20的槽缝27中,以帮助将患者运输装置联接构件20联接到侧臂运动基座25。虽然仅示出一个突出部,但可以构想包括另一突出部。可选地,可以结合一突出部垂直于另一突出部38的形式,使得两个叶片形成堆叠布置,从而增加可以承受的载荷。此外,患者运输装置联接构件20与侧臂运动基座25的联接也可以包括另外的紧固件。例如且不通过限制的方式,侧臂运动基座25可以包括带螺纹的螺栓23,该带螺纹的螺栓接合患者运输装置联接构件的对应的带螺纹的孔28。
另外,为了促进扶手10的转动,棘轮机构37设置有离散的定位槽缝39。当突出部38通过合适的致动机构(例如,按钮26)与患者运输装置联接构件20的槽缝27脱离接合时,突出部38可以在离散的定位槽缝39之间运动,由此帮助扶手10转动到不同的位置。如图9中所示,定位槽缝39限定出用于侧臂延伸件5的可能转动位置。在如图8和图9中示出的一个实施例中,侧臂运动基座25还可以包括锁定销36,用以限制扶手10的转动。具体而言,侧臂运动基座25的锁定销36在弯曲的槽缝41内运动。操作时,槽缝41限定出锁定销36的最大转动,由此限定出附接至锁定销的侧臂运动基座25和扶手10的最大转动。
参考如图10中所示的摆动机构,侧臂运动基座25包括静止杆30,该静止杆插入到扶手10的槽缝。参考图5和图11,扶手10被构造用来根据扶手10的摆动运动而围绕静止杆30枢转。如图10的实施例中示出地,该摆动机构包括内部弹簧33,该内部弹簧将扶手10维持在向外枢转的位置(见图11)或未枢转的位置(见图10)中。
参考图12,该弹簧可以通过合适的致动机构(例如桨状件闩锁)12脱离接合,该桨状件闩锁也被构造用来滑动地接合侧臂运动基座25的下部边缘34并因此防止扶手10的枢转。如图10中所示,拉动桨状件闩锁12的滑动杠杆13,使得桨状件闩锁12能够滑动地脱离接合,从而允许扶手10枢转。参考图13,在枢转之后,桨状件闩锁12可以接合侧臂运动基座25的上唇部35,从而将扶手10的位置固定在向外枢转的位置中。
在另外实施例中,可能希望的是减小摆动半径,例如,减小至大约90°,或者在特定实施例中减小至大约25°。参考图11,扶手10包括销32,该销能够在侧臂运动基座25的长形槽缝31内运动。扶手10的运动受限于销32在长形槽缝31内的运动程度。
另外,图14描绘侧臂延伸件5的剖视图,尤其描绘了增加侧臂延伸件5的耐用性的内部部件。例如,患者运输装置联接构件20与侧臂运动基座25的附接使用了衬套40,该衬套具有上凸缘构件41,该上凸缘构件环形地包围偏压构件(例如弹簧)43。衬套40具有用来接合螺钉构件45的带螺纹的下部分,这有助于将患者运输装置联接构件20紧固至侧臂运动基座25。当按钮26被压缩以释放扶手10时,按钮26可以接触使弹簧43压缩的梁44。
另外如图14中所示,虽然底部螺钉45保持将侧臂运动基座25紧固地堆叠在患者运输装置联接构件20上,但在该堆叠构造中可能会存有间隙——例如在上凸缘构件41下方的间隙,从而产生噪声效果。为了抵消潜在的噪声效果,可以在凸缘41下方设置波形垫圈42以保证该组件是紧密的。
虽然上述实施例涉及用于救护床的侧臂,但还构想该侧臂延伸件可以联接到其它患者运输装置,诸如折叠式搬运椅、轮椅、担架等。
本公开内容还涉及救护床床垫紧固部件。参考图15和图17,床垫50包括:患者支撑侧52;与患者支撑侧52相对的床框架联接侧54;以及床垫联接构件60,该床垫联接构件附接到床框架联接侧54,并被构造用来将床垫50附接到支撑框架3。参考图17-图21,床垫联接构件60限定外部环61、以及同心地布置在该环内的可转动插入件62。该可转动插入件62可操作以插入到支撑框架3的槽缝7中。
参考图18-图19和图21,在可转动插入件62被布置在槽缝7中之后,通过让凸缘构件64围绕中心销68转动,床垫联接构件60可以被固定在槽缝7中。以这种方式,具有比槽缝7更大直径的外部环61将接合支撑框架3的顶表面,而可转动插入件62在转动时接合支撑框架3的下表面(见图18)。如示出地,这些床垫联接构件60易于紧固并易于从支撑框架3的槽缝7脱离。因此,移除或更换床垫50的过程被简化。
在如图20-图22中示出的另一实施例中,床垫联接构件60可以包括通气孔69,用于释放任何积累的空气以防止床垫50中的“鼓胀”效应。如示出地,通气孔69通常被定位在外部环61上;然而,构想在床垫联接构件60或床垫50上的其它部位处设置通气孔69。在另一实施例中,床垫联接构件60可以包括布置在可转动插入件62上的通气孔69。
还应当注意,如“优选地”、“基本上”、“通常地”和“典型地”的术语在这里不用于限制要求保护发明的范围或暗示某些特征对于要求保护发明的结构或功能来说是关键的、必要的、或者甚至重要的。更确切地,这些术语仅仅意图凸显可以用于或不用于本发明特定实施例的备选或另外特征。
已经详细地并且通过参考本发明的特定实施例描述了本发明,将显然的是,在不偏离所附权利要求中限定的本发明范围的情况下,修改和变化是可能的。具体而言,虽然本发明的一些方面在这里被认为优选的或特别有利的,但可以构想本发明不必限于本发明的这些优选方面。
