Embodiment 1

[0041] figure 1 It is an embodiment of the automatic biochemical analyzer with dispensing unit of the present invention.

[0042] The main structure of the instrument includes two reagent trays 1, a reaction tray 5, a sample loading unit, an optical detection unit, a detection cup cleaning unit 2B, two distribution units and a sample needle 2C, and the sample loading unit adopts a circular sample tray 3; The two dispensing units are used to absorb and distribute reagents, and the sample needle 2C is used to absorb samples; a cleaning position 2D is provided beside the sample needle 2C for cleaning the sample needle 2C.

[0043] Wherein, the reagent plate 1 is provided with a plurality of reagent bottles 1-1, the reaction plate 5 is provided with a plurality of detection cups 6, and the optical detection unit includes a light source 5A, a monochromator 5B and an optical signal detector 5C;

[0044] The dispensing unit includes a needle moving arm 2A / 2A', a pipeline converter a...

Embodiment 2

[0053] Such as figure 2 , the difference between this embodiment and embodiment 1 is that the sample loading unit of this embodiment is a track-type sample rack 8, and has two distribution units, and there is a distribution unit near the position of the first reagent disk R1, and the distribution unit The pipeline converter has three needle positions; there is a distribution unit near the second reagent plate R2, and the pipeline converter of the distribution unit has two needle positions.

Embodiment 3

[0055] Such as Figure 3-4 As shown, in this embodiment, the cleaning of the needle in the dispensing unit is not limited to the inside of the needle, but also includes the cleaning of the outside of the needle. The cleaning device for the outside of the needle includes a cleaning agent nozzle 7-9 and a pure water nozzle 7-8, two The nozzles are all pointing to the tip of the hollow needle, and the pure water nozzle 7-8 is higher than the position of the cleaning agent nozzle 7-9. When in use, the cleaning agent is first sprayed to the outside of the hollow needle tip through the cleaning agent cleaning head 7-9, and then through the pure water nozzle. 7-8 Spray pure water to the outside of the hollow needle tip; the rinsed cleaning agent and pure water fall into the waste liquid collection tank below.

[0056] Or, only pure water spout 7-8 is set outside the hollow needle, as Figure 3-5 shown.

Abstract

The invention discloses a full-automatic biochemical analyzer with a distribution unit. The full-automatic biochemical analyzer comprises a reagent disk, a reaction disk, a stirring unit, a sample loading unit, one or more distribution units, a detection cup washing unit, an optical detection unit and a control and data analysis processing unit, wherein each distribution unit comprises one or more hollow needles, one pipeline converter, a needle inner part washing device, a needle outer part washing device, a waste liquid collecting tank and a needle moving device, and is used for sucking and distributing reagents and samples, independently used for sucking and distributing the reagents or independently used for sucking and distributing the samples. According to the full-automatic biochemical analyzer disclosed by the invention, the problem of cross contamination between different reagents and samples of a traditional full-automatic biochemical analyzer caused by incomplete washing of the inner parts of reagent needles and sample needles is solved, and the accuracy and the reliability of a detection result of the full-automatic biochemical analyzer are increased.

Description

technical field [0001] The invention belongs to the technical field of medical inspection and detection, in particular to a fully automatic biochemical analyzer with a distribution unit. Background technique [0002] Automatic biochemical analyzer is a commonly used testing equipment in medical institutions. One of the main problems in the use of existing instruments of this type is that a variety of different reagents are often used to detect different samples during detection, and the instruments all use shared reagent needles and sample needles to draw different reagents and different samples into each test cup When drawing reagents and samples, reagents and samples are often left inside and outside the needles, especially inside the needles, and it is difficult to clean thoroughly. In addition, medical testing instruments are required to run at a relatively high speed. Therefore, often There is not enough time to thoroughly clean the inside and outside of the reagent an...
