Abstract

本发明公开了一种尿液收集袋，其由限定流体储存室的至少一个柔性材料片形成，该尿液收集袋包括防回流阀。防回流阀包括限定流体容器的外壳，其开放进入流体储存室。外壳固定到尿液收集袋上，这样容器的开孔由上述至少一个材料片覆盖。在材料片中在位于外壳的开孔之下的位置处形成切口以限定垂片，该垂片悬挂于在流体容器中的开孔上。所述垂片可移动进入到流体储存室中，从而允许流体从容器流入到储存室中。从储存室朝向容器的流体流动导致垂片紧靠外壳的外围边缘密封，并从而基本防止上述流动。

Description

具有一体的防回流阀的尿液收集袋
技术领域
当前的公开内容涉及用于从插管患者收集尿液的尿液收集袋。更具体的，当前的公开内容涉及用于从插管患者收集尿液的尿液收集袋，其具有一体的防回流阀，以便基本防止流体从尿液收集袋流出并朝向插管患者回流。
背景技术
用于从插管患者收集尿液的尿液收集袋是众所周知的。典型地，尿液收集袋由柔性的、可折叠的前部和后部材料片形成，上述材料片在其外缘处密封在一起以限定一流体储存室。具有与插管患者流体连通的第一端部的入口管具有第二端部，第二端部设置为将尿液供应到尿液收集袋的入口孔。可在入口处将防回流阀配置到尿液收集袋上，以便防止流体从尿液收集袋中流到尿液收集袋外部并朝向插管患者回流。如果尿液收集袋颠倒翻转时上述现象会发生。
图1-3C示出具有已知防回流阀20的现有技术中的一个尿液收集袋10。尿液收集袋10包括第一和第二柔性的材料片22和24(图2B)，其限定可折叠的流体储存室26。适于和流体导管流体连通的入口管28具有排放端30，该排放端30设置为引入到防回流阀20中。
防回流阀20包括具有入口端口34的透明外壳32，上述入口端口34具有一定的尺寸以便接收入口管28的排放端30。外壳32限定设置在流体储存室26外部的流体容器36(图2B)，所述流体容器36具有进入到流体储存室26中的开口36a。外壳32包括周缘部分32a，其固定或焊接到第一柔性材料片22上。周缘部分32a限定一对设置在开口36a的相对侧上的销接收孔38。孔38构造为接收阀支撑元件40(图3B)的销40a，以便将阀支撑元件40邻近开口36a固定。阀元件42(图3C)包括具有用于接收支撑元件40的销40a的开孔44的柔性材料片。阀元件42支撑在销40a上并且在阀支撑元件40和外壳32的周缘部分32a之间被压缩到覆盖开口36a的位置。
如图3B中所示的，阀支撑元件40包括半圆形的托架46，该托架46保持阀元件42的上面部分处于紧靠外壳32的周缘部分32a的位置处。但是，阀元件42的下面部分42a搁置在外壳32的周缘部分32a的外表面上，但是能够自由向内移动进入储存室26，从而允许流体容器36中的流体进入储存室26。由于阀元件42悬挂于或搁置在外壳32的周缘部分32a上，因此从储存室26中流出的接触阀元件42的任何流体往往将阀元件42抵靠外壳32的周缘部分32a密封，从而防止从储存室26中流出的流体流入到外壳32中。
虽然上述现有技术中的防回流阀是非常有效的，但还是希望提供更廉价的和更容易制造的防回流阀。
发明内容
根据本发明的公开内容，公开了一种限定流体储存室的尿液收集袋，其包括一体地附连的防回流阀。防回流阀包括阀外壳，其限定没置在流体储存室外部的流体容器。阀外壳包括外围边缘，其诸如通过焊接密封到限定尿液收集袋的材料片上。由外壳限定朝向外围边缘内部的开孔。阀外壳开孔由材料片覆盖。在一个实施例中，在材料片中在位于外壳开孔销下方的位置处形成切口以限定垂片。垂片悬挂于外壳的外围边缘之上并且可向外移动进入到流体储存室中，从而允许流体从外壳容器流入到尿液收集袋的流体储存室中。从储存室朝向外壳容器的流动导致垂片紧靠外壳的外围边缘密封，并从而基本防止上述流动。使流体储存室和外壳容器互相连接的通气孔也可设置在材料片中。
在一个实施例中，阀外壳限定了流体入口管道，其具有一定的尺寸以接收入口管的一个端部。入口管与插管患者的导尿管流体连通。
尿液收集袋可由第一和第二柔性的材料片形成，上述材料片在其边缘处密封在一起以限定流体储存室。第一和第二材料片可由聚氯乙烯形成，但是也可使用其它的柔性材料。
在一个实施例中，阀外壳由基本透明的材料形成。可选择的，也可使用不透明的材料来构成阀外壳。
尿液收集袋可以包括排放阀，用于控制从流体储存室的流体的排出。一个或多个通气口也可设置在尿液收集袋中。

具体实施方式
现在将参照附图对当前公开的尿液收集袋的实施例进行详细描述，其中在上述几幅附图的每一附图中相同的参考数字指示相同的或相应的元件。
图4-8示出当前公开的尿液收集袋的一个实施例，通常表示为100。尿液收集袋100包括限定流体储存室102的至少一个材料片。在一个实施例中，尿液收集袋100包括第一和第二材料片104和106(图5B)，上述材料片在其边缘处诸如通过RF或超声波焊接密封在一起以限定流体储存室102。在一个优选的实施例中，尿液收集袋100由聚氯乙烯片构成。可选择的，也可使用其它柔性或可折叠的材料。收集袋100包括防回流阀120，将在下面对该防回流阀120进行进一步描述。收集袋100还可包括：一个或多个通气口180；用于将收集袋100安装到支撑结构例如床架上的支撑件或悬挂件106；用于控制流体从收集袋102排出的排放阀108；和/或入口管110。入口管110具有与插管患者的导尿管流体连通的一个端部(未示出)以及设置为将流体放置入防回流阀120中的第二端部110a。
参照图5A和图5B，防回流阀120包括具有外部边缘122a和主体部分122b的外壳122。外壳122优选由透明塑料形成，但是也可想到使用其它透明或不透明的材料。主体部分122b限定流体容器122d和具有一定尺寸以接收入口管110的第二端部110a的流体入口管道122c(图4)。第二端部110a可如图所示以一个角度切割，以降低在入口管110中形成弯月面的可能性。在管道122c一个端部中的开孔124允许流体从入口管110流入容器122d中。外壳122的后侧限定开孔126(图5A)，该开孔126开放进入流体储存室102中。可设置部分地围绕外壳122的邻近边缘122a的稳定肋130，以增加外壳122的刚性。
参照图5B和5C，外壳122的边缘122a诸如通过例如RF、超声波焊接等固定到尿液收集袋100的第一片104上，这样第一片104覆盖外壳122的开孔126。一个C形的切口136形成在片104中，以限定邻近开孔126的底部边缘126a的垂片138。垂片138悬于外壳122的边缘122a上，在片104中形成一小孔140。孔140使得储存室102和容器122d互相连接，从而当流体从容器122d流入到储存室102中时允许储存室102排气。一系列凸起或突出物182可围绕边缘122a设置，以防止垂片138紧靠边缘122a密封。
参照图6A和图6B，当流体流动通过入口管道122c进入容器122d中时，流体的重量导致垂片138从外壳122的边缘122a升起离开，从而允许流体从容器122d流入到储存室102中。相反，当流体从储存室102朝向防回流阀120流回时，流体的重量迫使垂片138下降到外壳122的边缘122a上，从而密封开孔126。由于垂片138结合在收集袋100的片104中，因此可提供更简单的、更容易制造的和更廉价的防回流阀。
应该理解可以对在此公开的实施例进行各种改型。例如，在此公开的结合垂片结构的防回流阀可具有没有在此示出的无数构造。而且，尿液收集袋可不必整体为柔性的，而是可以包括固定到限定垂片的柔性片上的刚性部分。因此，上述说明不应该解释为对本发明的限制，而仅是以优选实施例进行示范性的描述。本领域的那些技术人员可以想到在所附加权利要求限定的范围和精神内的其它改型。
