Description

一种微生物检验移液器
技术领域
本实用新型涉及医疗器械技术领域,尤其是一种微生物检验移液器。
背景技术
目前,微生物检验人员使用的吸球仅为平口橡胶吸球,该吸球不容易控制吸液流速,影响加样的速度和准确度。橡胶吸球平口处弹性欠佳且直径大小固定,不能包裹各种吸管以达到较好的密封性,不适合各种管径的吸管,特别是非常细的一次性吸管。传统的尖嘴吸球无法一人一手操作,拿吸球和吸管各需一只手,无法再拿试管等。
实用新型内容
本实用新型的目的是为了克服上述技术缺点,提供一种微生物检验移液器。
本实用新型解决技术问题采用的技术方案为:一种微生物检验移液器,包括吸囊,所述吸囊的下端开口处套在一个塑料管上,所述塑料管的内孔塞有橡胶锥管,橡胶锥管的内锥口套在吸管上口外周上。
所述吸囊顶部设置有气孔。
所述吸管上标有刻度。
本实用新型所具有的有益效果是:
本实用新型结构简单,操作方便,成本低,密封性好,适用于微生物检验人员加有毒试剂及培养基、理化分析人员迅速加各种检验试剂,一人一手可方便完成对试剂的吸入和吹出动作,有利于提高工作人员的工作效率。
附图说明
附图为本实用新型的结构示意图。
具体实施方式
下面结合附图对本实用新型做以下详细说明。
如图所示,包括吸囊1,所述吸囊1的下端开口处套在一个塑料管2上,所述塑料管2的内孔塞有橡胶锥管3,橡胶锥管3的内锥口套在吸管4上口外周上,所述吸囊1顶部设置有气孔6,所述吸管4上标有刻度5。操作时抓住吸囊1,用手指堵住气孔6,挤压吸囊1,吸管4下口插入在需要吸取的液体内,释放对吸囊1的挤压,将液体吸到吸管4内,然后释放对气孔6的封堵,将吸管4内多余的液体慢慢排掉,使液面到达吸管需要量的刻度线位置,然后将吸管转移到需要添加的试管处,松开对气孔的封堵将吸管内的液体排出。

Claims (3)

1.一种微生物检验移液器,其特征在于:包括吸囊,所述吸囊的下端开口处套在一个塑料管上,所述塑料管的内孔塞有橡胶锥管,橡胶锥管的内锥口套在吸管上口外周上。
2.根据权利要求1所述的一种微生物检验移液器,其特征在于:所述吸囊顶部设置有气孔。
3.根据权利要求1所述的一种微生物检验移液器,其特征在于:所述吸管上标有刻度。
