一种检测移液器用快捷装配枪头A quick assembly pipette tip for detecting pipettes

技术领域technical field

本实用新型具体涉及一种检测移液器用快捷装配枪头。The utility model particularly relates to a quick assembly gun head for detecting a pipette.

背景技术Background technique

在生化实验、医学检验的液态或半液态样本提取过程中，样本在从抽取到运送到实验室的时间一般较长，往往距离安排提取还需一段时间，因此在这段时间内样本(例如血液样本)易变成粘稠状或凝固成块，而在样本提取过程中不易将采血管倾斜以使血样流到管口进行吸取，而采用现有两个或三个现有移液器枪头套在一起提取样本，可能会出现脱落的情况，导致浪费样本材料，同时污染样本，甚至导致实验失败。目前市面上所销售的移液器，普遍采用了同一种设计，即所有的移液器都没有过滤装置，使得移液器在使用时经常发生吸液口堵塞等问题。During the extraction of liquid or semi-liquid samples for biochemical experiments and medical tests, the time from extraction to delivery to the laboratory is generally long, and it often takes some time before the extraction is scheduled. The sample) is easy to become viscous or coagulate into a block, and it is not easy to tilt the blood collection tube during the sample extraction process to make the blood sample flow to the mouth of the tube for suction, and the existing two or three existing pipette tips are used. When samples are taken together, they may fall off, leading to waste of sample material, contamination of samples, and even failure of the experiment. Currently, the pipettes sold on the market generally adopt the same design, that is, all pipettes do not have a filter device, so that the pipette often has problems such as blockage of the suction port during use.

然而现有的枪头在使用时，因拆装不方便，因此在使用时对于操作方便性、工作效率有明显的影响。However, when the existing gun head is in use, it is inconvenient to disassemble and assemble, so it has a significant impact on the convenience of operation and the work efficiency during use.
