Description

具有英蒂格莱尔泵模板的容器
技术领域
本发明涉及用于收集和排出液体的制品的工艺。特别是，本发明涉及一种可方便使用的容器，用来收集生理液体并将该液体传送到另一个容器。
背景知识
众所周知，从外科场所收集液体，比如血液，是利用真空压力。这样收集的血液通常进行去除空气和粒状污染物的处理。已知的生理液的过滤器具有这样的特点，即，一个管状的入口与一个筒形的输入腔体相切从而产生离心力使空气从收集液中分离，由物理过滤器进一步去除粒状污染物。但是，这些装置不易于收集液排出，而且无法用阻凝剂和类似物质对收集的血液进行有效处理。
发明概述
根据本发明，一个血液收集腔包括一个真空腔，用来储存收集液，例如血液或其他生理液。该容器的一个整体部分形成一个泵的至少一个部分，该泵用来从该容器中排出收集液。在最佳实施例中，该腔体用在一个从一外科扬所真空收集血液和其他生理制品的系统中。
该容器分成上下两个腔，上腔呈筒形，从外科场所接收液体并执行空气和残渣从液体中的一个初始分离，该初始分离的完成采用如下方式，即将液体导入该腔形成一个涡流。随后，液体通过上下腔之间的一个滤网进一步净化。在最佳实施例中，通过沿与该上腔相切的方向引入该液体而生成涡流。一真空口与下腔相通，形成一压差将液体从外科场所吸入到上腔，随后借助重力，由上腔进入下腔。
上腔具有一个入口，用来使一种第二液体与收集液混合。在最佳实施例中，第二液体是一种阻凝剂。吸入该腔的阻凝剂的量是真空度的一个函数。相应地，吸入的液体越多，则吸入的阻凝剂也越多，从而使阻凝剂对收集在容器内液体的比例得以保持，这样就无需为冷凝剂单独设泵或测量装置。
本发明的另一个特点是具有将收集液从该容器中排出的装置，由于该容器处于负压作用下，收集液必须从该容器内抽出。一种已知类型的泵是一辊子泵，而且，下腔的底部为该辊子泵形成一个模板。输出管紧邻该模板设置，以便在容器放在辊子上时，由辊子将输出管压向模板。这样，该辊子泵由该管而自动加载，并且在容器放在包括该辊子的支承上后，该泵可以立即工作。
附图简述
图1是根据本发明的一个容器的一个透视图；
图2是图1中所示的安装在一个辊子泵基座上的容器的一个横断面图；
最佳实施例详细说明
参照图1，根据本发明的一个容器400包括一个上部件402，它与一个下部件404联接。该上部件包括一个外壁406和一个内壁408，它们形成一个大体呈筒形的上腔，还包括一个液体入口410。该上腔的底板包括一个粒状物过滤器412，具有400微米到600微米范围内的网孔。一个真空口414与一个由壁408形成的内腔相通，该内腔与由下部件408构成的下腔敞开式联通。
当真空，例如由一个真空泵(未示出)产生的真空，作用于口414时，空气和液体被吸入入口410内。该入口最好是管状的，并且该管的轴线与上腔相切。来自于外科场所的液体在上腔形成一个涡流，开始了空气和残渣从液体的分离。该涡流由一隔板416终止。液体和空气随后通过将残渣从液体中去除的过滤器412。液体和空气在重力和存在于上下腔之间的由过滤器412的存在而产生的压力梯度共同作用下通过过滤器412。
一种第二液体，最好为一种阻凝剂，通过口418导入上腔内的液体。例如，一袋阻凝剂可悬挂在容器上方并由一柔性管与口418联接。该口418的底部由一多孔盘420覆盖，该盘又与上腔联通。吸入上腔的阻凝剂的量主要取决于上腔内的真空度。因此，如果真空加大，通过入口410吸入的液体量加大，通过口418吸入的阻凝剂量也加大。这使得阻凝剂在收集液和阻凝剂的混合物中的比例当真空度被控制时保持恒定。而且，由于该盘为上腔提供了一个相对大的表面积，在口418内的压力可容易地加到足够大以将所需量的阻凝剂吸入到液体中，而无需利用另一个为入口410内所需的真空度而设的机械泵。
在最佳实施例中，作用于口414的真空压力是这样控制的，即，该真空压力只根据与口410相通的收集管内液体的探测结果而增加(比如约-100毫米汞高)。当系统确定了收集管内无液体，比如利用检测出收集管的压力降超过一限定值，真空压力便减到很小程度(比如约-20毫米汞高)。这样，当系统不收集液体时，极少量的或根本没有阻凝剂由于减小的真空而被吸入腔内。
盘420最好用一种已知的多孔材料制成，比如烧结的聚乙烯制成，具有10微米到20微米范围内的孔。另外一种选择是，可单独采用一机械阀或者阀同该多孔盘一起采用。阻凝剂的流畅通过取决于如下变量，如盘材料的疏水性、厚度和几何形状；或者在使用阀的情形下，则取决于阀的开启压力和节流。
收集在容器内的液体422储存在下腔内，该腔还包括用来通过一排出口424排出液体422的装置。该排出装置最好包括一个辊子泵，该泵包括一个已知结构的辊子组合426，该辊子组合安装后可绕一水平轴旋转。一个辊子泵需要一模板与该辊子组合共同作用，根据本发明，该模板形成在容器的底面内。因此，一个柔性出口管428与一个紧邻一个位于容器底部内的凹部430的排出口424连接，该容器的底部形成辊子泵的模板。出口管428通过和口424和一个夹子432的联接，刚好支承在模板430的下方。当容器入在辊子426上时，管428被向上推，与模板430接触，并在模板和辊子之间受压。收集液随后借助于辊子426的旋转而排出。
需要的话，可在排出口的上方设置一第二过滤器434，为液体在排出前进行再净化。
所附权利要求范围内的改变，对熟知本行业的人士是显而易见的。
