Description
本發明是有關一種分注吸管密封裝置,其包含一抽吸裝置、二個裝設於該抽吸裝置兩側的密封調整裝置、一具有複數個分注吸管的分注管組、一用於實施抽取的推拉桿裝置與一驅動裝置,透過該驅動裝置帶動該推拉桿裝置,使該推拉桿裝置令該抽吸裝置產生負壓,以利於各該分注吸管可同時分注的抽取液體樣本。The present invention relates to a dispensing suction pipe sealing device, which comprises a suction device, two sealing adjustment devices installed on both sides of the suction device, a dispensing pipe set with a plurality of dispensing suction pipes, a A push-pull rod device for extracting and a driving device, the push-pull rod device is driven by the driving device, so that the push-pull rod device generates negative pressure on the suction device, so as to facilitate the extraction of liquid samples that can be dispensed by each dispensing pipette at the same time .
生物科技運用之層面廣泛,其發展有助於運用在醫療、保健、飲食,也觸及生物基因、遺傳、疾病之研究,是相當重要的一項科技發展。The application of biotechnology has a wide range of levels, and its development helps to be used in medical treatment, health care, diet, and also involves the research of biological genes, heredity, and diseases. It is a very important technological development.
在各項運用之中,常需使用分注器/管(或稱移液器/管)來對液體樣本進行取液,該分注器/管係採針筒原理,將分注管內抽真空以吸取液體樣本,因此,管內必須有良好的密封效果,才可維持良好的抽取效果,現有一種多管型式的分注器/管可一次同時採集多管樣本,相當具有使用效益。In various applications, it is often necessary to use a dispenser/tube (or pipette/tube) to take liquid samples. Vacuum is used to draw liquid samples. Therefore, the tube must have a good sealing effect to maintain a good suction effect. There is a multi-tube type dispenser/tube that can collect samples from multiple tubes at one time, which is quite useful.
然所述多管型式的分注器/管,由於在組裝時必須安插多組吸管,在該吸管套接的接縫必須使用緊配合的密封環才可維持良好的密封效果,但也因此增加組裝的難度,尤其是組數多的該吸管;反之,若將該吸管套接的接縫與該密封環採較鬆的配合鬆緊度,則可能出現密封強度不足,影響使用效益。However, for the multi-tube type dispenser/tube, since multiple sets of suction tubes must be inserted during assembly, tight-fitting sealing rings must be used at the joints of the suction tube sockets to maintain a good sealing effect, but it also increases the Difficulty in assembly, especially for the straws with a large number of groups; on the contrary, if the joints of the straws are sleeved with the sealing ring with a loose fit, the sealing strength may be insufficient, affecting the use efficiency.
另外,針對所述多管型式的分注器/管,所運用的層面與範圍不同,必須替換不同組數的該吸管使用,若該多管型式的分注器/管只是單一尺寸的設計,顯然實用性不足。In addition, for the multi-tube type dispenser/tube, the level and scope used are different, and different groups of the straws must be replaced. If the multi-tube type dispenser/tube is only a single size design, Obviously not practical enough.
因此,本發明設計了一密封調整裝置,該密封調整裝置可隨操作控制該密封環與該吸管之間的密封效果,在緊迫時提升氣密度,在鬆放時則可更輕易的安裝或拆卸,另外又設計了一連接裝置,該連接裝置可利於各部結構相接固定亦或是分離拆除,以方便清洗維護或拆換具有不同組數配置的結構,提升了整體實用性,如此為本發明分注吸管密封裝置之解決方案。Therefore, the present invention designs a sealing adjustment device, which can control the sealing effect between the sealing ring and the straw according to the operation, improve the air density when it is urgent, and can be installed or removed more easily when it is released. , In addition, a connecting device is designed, which can facilitate the connection and fixation of each part structure or the separation and dismantling, so as to facilitate cleaning and maintenance or dismantle and replace the structure with different groups and configurations, and improve the overall practicability, so this is the present invention.
