Carrying mechanism of a turntable measuring cup and its use method

Abstract

The invention discloses a rotary disk type measuring cup carrier mechanism and a use method thereof and relates to the technical field of trace element detection. The rotary disk type measuring cup carrier mechanism mainly comprises a fixed disk body, a rotating disk body, a lifting cleaning table, a detecting electrode, a plurality of liquid suction needles, a plurality of liquid feeding needles,a wiping device, a plurality of detection liquid outlet needles, a sample liquid outlet needle and a stirring device. The rotary disk type measuring cup carrier mechanism can keep a fixing state of the electrode in detection and an electrode movement mechanism is avoided so that the problems of safe risk of the electrode movement and measuring errors caused by the electrode movement are solved. The detection electrode can be cleaned in detection so that the complex manual cleaning process is avoided and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of trace element detection, in particular to a carrying mechanism of a turntable measuring cup and a use method thereof. Background technique [0002] Trace element analyzers mostly refer to instruments that test the content of trace elements in the human body. There are a lot of things on the market, but the most accurate formal test results should be electrochemical analysis methods, atomic absorption methods and mass spectrometry (ICP-MS). Among them, atomic absorption method and ICP are high-end products, and the price generally ranges from hundreds of thousands; however, with the development of medical conditions, most hospitals and community health service centers below the top three use electrochemical analysis instruments, and the current market share maximum. Electrochemical analysis is a high-end product with simple operation, accurate and reliable test results, and low daily consumables, so it i...

Problems solved by technology

[0003] However, the existing electrochemical trace element analysis instruments still have the following problems: ①Due to the difficulty of cleaning, the measuring cups are generally plastic cups, and the traditional plastic measuring cups can only be used once, which not only brings waste of data, but also has waste disposal, Environmental pollution problems; ②The electrode needs to be moved during the measurement process. The electrodes of the trace element analyzer are generally large in size, and the moving electrode requires a large and heavy movement mechanism, which cannot be transferred quickly and affects the measurement rate. In addition, the electrode movement process There is a risk of damage, and the movement of the motor can easily lead to problems such as air or mercury liquid faults in the capillary; ③The cleaning of the existing detection electrodes is manual cleaning, which not only slows the cleaning speed, but also increases the labor intensity
