A fully automatic trace element analyzer

Abstract

The invention discloses a full-automatic trace element analyzer, which relates to the technical field of trace element detection. The full-automatic trace element analyzer mainly comprises a fixed disk, a rotating disk, a driving shaft, a cleaner, a sample adding device, a test electrode, a liftable cleaning platform and the like. A slide rail and a slide way which cooperate with each other are arranged between the rotating disk and the fixed disk to prevent the rotating disk from vibrating up and down during rotation; contact sensors cooperate with balls, an audible and visual alarm gives analarm to remind an operator to replace or adjust the instrument in time when the rotating disk does not rotate in place, the cooperation between triangular fastening blocks and slots can prevent the rotary shaft from slightly rotating when the rotating disk rotates in place, and thereby the accuracy of measurement is ensured; and the number of measuring cup holes in the rotating disk can be permanently designed as six. The practicability is high.

Description

technical field [0001] The invention relates to the technical field of trace element detection, in particular to an automatic trace element analyzer. 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 formal test results should be accurate electrochemical analysis method, atomic absorption method 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 is favored by hospitals. [0003] However, the...

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 electrode 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 down the cleaning speed, but also increases labor intensity; ④Some rotating disks The rotating disk of the type trace element analyzer has poor applicability. Different measuring cups require different types of cleaning solutions. Each additional cleaning solution requires one more liquid addition step and one suction step. At the same time, two more steps are required on the rotating disk There are four measuring cup holes, and the types of detection liquid required for various detection samples are also different, and the number of measuring cup holes on the existing rotating disk is fixed, so it is difficult to apply the required; ⑤ rotating disk is rotating It is easy to shake and cause liquid to spill out. Since the upper cleaning device, test electrode, liquid adding device, etc. and the lower measuring cup hole have a high degree of cooperation, the rotation angle of the turntable is required to be very accurate. The existing turntable rotates one When working at the station, there may be a situation where the transfer is not in place, which may lead to test errors; how to design a fully automatic trace element analyzer that is easy to clean the measuring cup and the detection electrode and does not require the detection electrode to move is the object of the present invention.
