Description

超声系统控制面板和显示器升降机
发明领域
本发明涉及医疗诊断超声系统，并且特定来说，涉及具有可调整的控制面板和显示器高度的超声系统手推车。
背景技术
手推车运载的超声系统是方便医疗成像器械，因为其可容易地设立于成像实验室中或当需要时滚动到患者的床边。其在传统上由超声波检查医师以不同姿势使用：站立、坐着、或倾身于被扫描的患者上方。在这些位置中的任何一个中，对于超声波检查医师来说，重要的是将控制面板定位于所谓的“用户区域”中，以便其可舒适地接近并且实现显示屏幕的容易操纵，以便其在扫描时可被接近地观察。为了完成这些调整，控制面板和系统显示器有必要具有水平和垂直的宽广范围的运动。在正确地定位控制面板和显示器之后，控制面板必须牢固地保持于适当位置并且在超声波检查医师操纵控制时不移动或摇摆。本发明针对满足这些目标。
发明内容
根据本发明的原理，提供一种用于超声系统的升降机，所述升降机使得控制面板和显示器能够被提升到不同高度并且枢转到对于超声波检查医师来说舒适的位置。所述升降机允许借助于所述控制面板上的把手手动地定位所述控制面板，其中所述控制面板的重量由所述升降机中的液压支柱抵消。所述升降机含有四连杆机构，所述四连杆机构在所述控制面板被提升和/或旋转时维持其倾斜。当所述控制面板处于期望的位置中时，所述液压支柱和枢转轴线由螺线管锁定以将所述控制面板牢固地维持到位。为安全起见，在所述手推车滚动到不同位置或场所中时锁定所述升降机。

图2图示用于本发明的超声系统的控制面板升降机的分解视图。
图3是图2的组装的控制面板升降机的透视图。
图4图示处于其完全折叠的位置中的图3的控制面板升降机。
具体实施方式
首先参考图1，示出手推车运载的超声系统10。手推车的基座是含有超声系统的电子器件(例如，印刷电路板)的外壳12。在外壳的后部处的是其中可存储或安装配件(例如，探针、录像机、胶瓶和电缆)的隔室。手推车具有轮子20以便手推车可滚动到需要其之处。手推车的在轮子之间的中心是制动踏板22，用户可下压所述制动踏板以锁定轮子以便手推车在其为了检查而已被定位之后将不滚动或移动。
在外壳12上方的是控制面板14，超声波检查医师通过所述控制面板操作超声系统和控制扫描程序。显示屏幕16安装于控制面板上方，超声波检查医师可在操纵控制面板的控制或扫描患者时在此处观察屏幕。显示屏幕安装于铰接臂18的端部处，所述铰接臂允许屏幕被升高、降低、倾斜和移动或转动到左侧或右侧以便将屏幕定位于方便的位置中以供在扫描时观察。铰接臂更完全地描述于第US2008/0234577号美国专利公开案(M urkow ski等人)中。根据本发明，控制面板14和显示器16附接到升降机30的顶部，所述升降机安装于手推车外壳12上。升降机使得控制面板和显示器能够被升高、降低、左转和右转和摆动到手推车的基座的一侧或另一侧。这个运动范围允许超声波检查医师将控制面板和显示器定位于最方便之处以在扫描患者时操作控制并且观看屏幕上的超声图像。升降机30被构造为在其被移动时将用户区域以固定倾斜维持的四连杆机构。用户区域由超声波检查医师通过抓住在控制面板的前部处的把手24同时下压把手上的释放按钮26来定位。释放按钮是安装于把手的中心中的发光开关。下压释放按钮导致其变亮并且释放机构臂中的若干机构(如下文所描述)，所述机构臂允许臂升高或降低和围绕所述臂的任一端部旋转。在超声波检查医师使得用户区域在期望的位置中之后，超声波检查医师释放按钮26并且机构牢固地锁定于其当前位置中。超声波检查医师然后可扫描患者而不导致用户区域的任何其它运动或摇摆。
图2是图1的升降机30的部件的分解视图。相同枢转弯头70位于升降机的顶部和底部处。每一弯头具有分别附接到外壳和控制面板组件的基板32a、32b。每一基板支撑将弯头组件保持轴向对准的轴向分度(journal)轴承并且使其居中。每一轴向轴承由从轴承集结部40到基板32的中心孔口中的中心环形突出部形成。推力轴承34承受控制面板和显示器的重量并且允许其被旋转。每一基板具有齿的圆形布置结构，所述齿由螺线管控制的销48接合以将机构锁定于其当前的旋转定向中。销48安装于导向轴承52中并且由压缩弹簧49推动成与齿轮齿接合。旋转止动件36位于每一弯头中以将旋转限制到360°。每一弯头具有轴承集结部40，在其表面中具有一个或多个掣子凹坑。当控制面板与轮子对准地面向时，所述凹坑中的一个标记控制面板相对于外壳的笔直向前位置。当控制面板处于笔直向前位置中时，球塞50掉落到轴承集结部中的笔直向前凹坑，从而当控制面板如此定位时给超声波检查医师掣子的触感。O型环38、42和44使弯头组件完整。
安装于每一基板的轴承集结部40上的是一对弯头框架80和82。弯头框架各自支撑三个枢转轴，用于为弯头安装盖子90的轴84a和84b，和用于安装形成机构的臂的连杆72a和72b的轴74a、74b、74c和74d。所述轴通过轴轴承86安装以便其可在框架中自由地转动。轴74a、74b、74c和74d以及连杆72a和72b组装以形成四连杆机构，所述四连杆机构就像平行四边形，当调整所述机构的高度时保持弯头向上和向下定向。这维持用户区域相对于地板的倾斜。在连杆72a、72b的每一侧上安装于枢转轴58a和58b上的是液压支柱62a和62b。所述支柱可以是气体或流体支柱并且操作成支撑控制面板和显示器组件的重量，从而在其由超声波检查医师重新定位时实际上抵消其所有重量。释放外壳64a、64b安装于每一支柱的活塞的端部处，并且螺线管60、61安装于每一释放外壳上以将支柱以其当前的活塞延伸锁定。当超声波检查医师下压控制面板把手上的按钮28时，螺线管60、61被通电，从而打开每一支柱中的阀以便在调整用户区域高度时每一支柱中的气体或流体可流动。当按钮被释放并且螺线管不再被通电时，阀闭合，阀充当制动器以将支柱锁定于其当前的活塞延伸位置中。
螺线管56a和56b安装于弯头中以控制每一弯头中的销48。当螺线管56a和56b通过按钮28的下压通电时，销48被拉出与每一弯头中的齿的接合，从而准许弯头组件70自由地旋转。在超声波检查医师已将控制面板转到其期望的定向时，按钮28被释放并且销48掉落到齿中，从而锁定弯头并且防止两个弯头的任何进一步旋转。用户区域的旋转和高度然后牢固地锁定到位。
根据本发明的又一方面，开关在按钮与四个螺线管之间。这个开关在轮子制动器22被下压以锁定轮子时闭合，并且当轮子制动器22被释放以滚动手推车时打开。这意指当制动器22接合以锁定轮子20时升降机的螺线管仅可被通电以调整升降机的高度和旋转。当制动器22被释放以滚动手推车时，螺线管不可被通电，并且升降机锁定到位。这防止在手推车不同位置间滚动时升降机、控制面板和显示器四处摆动或移动，从而确保当手推车移动时其被锁定到位。这个特征防止对操作员或其它人员的伤害以及对超声系统或其它物件的损坏。
根据本发明的又一方面，开关位于轴承集结部中的每一个的笔直向前掣子中并且联接到制动器22。这个开关控制制动器22的制动器释放中的螺线管，并且被布置成使得制动器不能释放以滚动轮子，除非每一球塞50接合于其笔直向前掣子中并且控制面板和显示器定位于其笔直向前位置中。这确保当手推车移动时控制面板和显示器的重量相对于外壳居中，这对大多数用户来说更容易并且更方便操纵。
图3图示当完全组装并且处于稍微降低的高度中时的图1和2的升降机30。可看出，弯头板32a和32b的上部和下部表面保持彼此平行。这个视图示出安装于其安装销84a和84b上的弯头盖子90。
图4示出当完全地降低时图3的升降机。看出弯头板32a和32b的表面在升降机30的这个和所有其它位置中保持平行。
