Description
本发明涉及液体收集技术领域，具体地说，是一种利用收集器来收集液体至封闭收集管中的方法。
随着生活水平的稳步提升，人们对于健康的关注也与日俱增。与此同时，现今工作方式的改变使得人们经常出现久坐、饮水少等问题，长期不良的工作方式引起了诸多危害人们健康的泌尿疾病，比如肾结石、尿路感染、前列腺炎等。因此，在医院常规诊疗中尿常规和尿沉渣等实验室检查也在逐年增加。
目前临床上主要使用的一次性液体采集器由简单的一次性液体采集杯和一次性液体采集管组成。医院提供给患者一个液体采集管和一个塑料敞口采集杯，患者在卫生间先用塑料敞口采集杯收集液体，再将液体倒入液体采集管中，采集所需体积的液体样本后盖上盖子。由于现有的液体采集过程是分段完成的，采集过程中经常出现液体易溅、易洒、操作不便等问题，不卫生采集的液体长期以来成为实验室检查项目污染源之一。液体样本暴露于外界环境中易被异物和细菌污染，并且患者及医务人员极有可能与致病性液体样本接触，安全风险性大。
现有最新的一次性液体采集器也由液体采集管和液体采集杯组成，采集完成后需要患者或者医务工作者盖上液体采集管的盖子，增加了交叉感染的风险。此外，有的采集器是竖着使用的，女性在使用时不太方便收集液体。
中国专利文献：201620428875.6，申请日2016.05.12，专利名称为：医用液体采集器。公开了一种医用液体采集器，包括：用于盛装留存的液体的壶体；安装在壶体的壶口处的壶盖；设置在壶体外壁上的用于抽取壶内液体的取样口；安装在取样口处的用于将其密封的密封帽。该实用新型的医用液体采集器，结构简单，使用方便，适用于需要收集多次尿液进行总量计量或需要计量并检验的患者，在收集尿液时不会污染操作者的手，采集的尿液不会外洒，易于留取需检验的尿样。
中国专利文献：201620867655.3，申请日2016.08.10，专利名称为：液体采集器。公开了一种液体采集器，包括：取液件、连接件以及储液管，所述取液件与所述储液管通过所述连接件可拆卸连接；所述取液件设有取液 腔，所述连接件包括连接管，所述储液管设有储液腔；所述取液腔和所述储液腔通过所述连接管连通。该实用新型液体采集器，取液件的取液腔接取液体，液体通过连接管流入储液管的储液腔内，取液过程不需要人工倒液，操作简单，且避免液体洒漏，避免污染储液管外壁。采集完液体后，将储液管和取液件拆分开，储液管送去检测即可，非常方便。此外，设置定量控制件，可以非常方便地获取定量的液体，使得液体留样量准确，不会过多也不会过少，便于后续检测。
上述专利文献201620428875.6中的医用液体采集器结构简单，且使用方便，适用于需要收集多次尿液进行总量计量或需要计量并检验的患者，在收集尿液时不会污染操作者的手，采集的尿液不会外洒，易于留取需检验的尿样；而专利文献201620867655.3中的液体采集器，取液件的取液腔接取液体，液体通过连接管流入储液管的储液腔内，取液过程不需要人工倒液，操作简单，且避免液体洒漏，避免污染储液管外壁。采集完液体后，将储液管和取液件拆分开，储液管送去检测即可，非常方便。此外，设置定量控制件，可以非常方便地获取定量的液体，使得液体留样量准确，不会过多也不会过少，便于后续检测。但是关于一种液体采集过程为封闭式采集，液体直接收集至封闭采集管，无需二次分装，减少了交叉污染，增加了检测结果的准确性，液体采集完成后可任意放置，方便医护人员的拿取的一种利用收集器来收集液体至封闭收集管中的方法目前则没有相关的报道。
综上所述，亟需一种液体采集过程为封闭式采集，液体直接收集至封闭采集管，无需二次分装，减少了交叉污染，增加了检测结果的准确性，液体收集完成后可任意放置，方便使用人员拿取的一种利用收集器来收集液体至封闭收集管中的方法。

实施例2
请参看附图10，图10是本发明某些实施例中在正压作用下利用收集器来收集液体至封闭液体收集管的示意图。本实施例与实施例1基本相同，其不同之处在于，本实施例中的液体收集器1与液体导管2为一体式结构，所述液体收集器1与空气导管3为分离独立连接式结构；所述液体收集器1在进行液体收集时，所述液体收集器1上外加一个加压装置(图中未示出)，所述加压装置与所述液体收集器1之间可以为固定式或分离式连接；液体在正压作用下进入所述封闭液体收集管4，一方面可加快液体收集的速度，另一方面，在收集某些液体时需要进行过滤等步骤，则可在所述收集器中再设置有过滤装置(图中未示出)，通过正压作用便可使得液体中的颗粒物与液体轻松分离实现液体收集。
实施例3
请参看附图11，图11是本发明某些实施例中在负压作用下利用收集器来收集液体至封闭液体收集管的示意图。本实施例与实施例1基本相同，其不同之处在于，本实施例中的液体收集器1在进行液体收集时，所述空气导管3末端外接一个抽吸装置(图中未示出)，所述抽吸装置与所述空气导管3之间可以为固定式或分离式连接；液体在负压作用下进入所述封闭液体收集管4，一方面可加快液体收集的速度，另一方面，在收集某些液体时需要进行过滤等步骤，则可在所述收集器中再设置有过滤装置(图中未示出)，通过负压作用便可使得液体中的颗粒物与液体轻松分离实现液体收集。
实施例4
本实施例与实施例1基本相同，其不同之处在于，本实施结合实施例2中的正压收集和实施例3中的负压收集，从而形成正压和负压同时进行的液体收集方式，从而使得液体收集的过程更加快速，有利于节省时间。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员，在不脱离本发明方法的前提下，还可以做出若干改进和补充，这些改进和补充也应视为本发明的保护范围。
