Description
技术领域 technical field
本发明涉及一种液体转移输送装置，特别是一种加吸液装置，还涉及一种细胞遗传学实验室细胞收获装置，应用于临床实验室和仪器设备技术领域。 The invention relates to a liquid transfer and delivery device, in particular to a liquid suction device, and also to a cell harvesting device in a cytogenetics laboratory, which is applied in the technical fields of clinical laboratories and instruments and equipment.
背景技术 Background technique
细胞遗传学技术通过在显微镜下进行染色体分析，对可能存在的染色体缺陷进行诊断。临床上染色体制备需要先对细胞进行培养，再进行加秋捕获、低渗、固定、干燥、老化、酶消化和显带等处理，才可以在显微镜下对细胞的染色体进行分析，以判断是否存在染色体异常。这一传统方法在建立之初一直沿用至今。 Cytogenetic techniques diagnose possible chromosomal defects by analyzing chromosomes under a microscope. Chromosome preparation in clinical practice requires the cells to be cultured first, and then processed by adding autumn capture, hypotonicity, fixation, drying, aging, enzyme digestion and banding, etc., and then the chromosomes of the cells can be analyzed under a microscope to determine whether there are Chromosomal abnormalities. This traditional method has been used since its inception.
对培养的细胞进行收获是细胞遗传实验室日常进行的重要工作环节，此环节的基本工序如下：将细胞转移到离心管中；低速离心后吸除上清；加入低渗液作用15分钟后加入固定液作用5分钟；离心后吸除上清，加入新固定液混匀；再次离心后吸除上清，加入新固定液混匀，重复3次；细胞收获完成。由上可见，收获过程中存在多次反复的吸液、加液、混匀、离心操作，其中除离心过程借助离心机完成外，其他操作均由手工操作完成。 Harvesting the cultured cells is an important part of the daily work of the cytogenetic laboratory. The basic procedures of this link are as follows: transfer the cells to a centrifuge tube; absorb the supernatant after low-speed centrifugation; add hypotonic solution for 15 minutes and then add The fixative was applied for 5 minutes; after centrifugation, the supernatant was removed, and new fixative was added to mix; after centrifugation again, the supernatant was removed, and new fixative was added to mix, repeating 3 times; the cell harvest was completed. It can be seen from the above that there are many repeated operations of absorbing liquid, adding liquid, mixing, and centrifuging during the harvesting process. Except for the centrifuge process, the other operations are all done by hand.
手工进行加吸液操作必然存在个人差异，每次吸除上清后的残余液体量、每次加入的新鲜液体量，均不可避免的存在较大的批次间差异，从而对细胞收获的结果产生一定的影响，导致结果的不稳定。 There are bound to be individual differences in the manual operation of adding liquid. The amount of residual liquid after removing the supernatant and the amount of fresh liquid added each time inevitably have large batch-to-batch differences, so the results of cell harvesting have a certain influence, leading to the instability of the result.
手工操作时需要用吸管多次操作，如每次加或吸8ml左右液体时需要使用3ml吸管反复操作3次，处理标本量较少时尚可承受，但当需要同时处理较多标本量20个以上时，操作时间长、工作量大，容易造成人员手疲劳。此外，手工加吸样时固定液贮存瓶敞开，刺激性液体弥散也对操作人员造成一定的化学危害。 Manual operation requires multiple operations with a straw. For example, when adding or sucking about 8ml of liquid each time, you need to use a 3ml straw for 3 repeated operations. It is acceptable to handle a small amount of specimens, but when more than 20 specimens need to be processed at the same time When the operation time is long and the workload is heavy, it is easy to cause hand fatigue. In addition, when the sample is added manually, the storage bottle of the fixative is opened, and the dispersion of the irritating liquid also causes certain chemical hazards to the operator.
