Embodiment 1

[0074] as attached figure 1, a fully automatic biochemical analyzer with a multi-needle rotation device, the instrument includes two reagent trays 1, a sample tray 3A, a reaction tray 5, a stirring unit, an optical detection unit, a detection cup cleaning unit 2B, and two multi-needle rotation device and a sample needle; the optical detection unit includes a light source 5A, a monochromator 5B, and an optical signal detector 5C; Needle moving arm 2C.

[0075] There are a plurality of reagent bottles 1-1 on the two reagent discs 1, which are respectively used to place reagent one and reagent two; the sample disc 3A is used to place samples; the reaction disc 5 is also provided with a plurality of detection cups 6 , used to place the detection cup; the optical detection unit is used to detect the liquid in the detection cup; the detection cup cleaning unit 2B is used to clean the detection cup; The rotation device is composed of two hollow needles and two sets of pipelines. Ea...

Embodiment 2

[0078] as attached figure 2 , The difference between this embodiment and Embodiment 1 is that the sample loading method in this embodiment is an orbital sample feeding device 3B.

Embodiment 3

[0080] as attached Figure 4 , the difference between this embodiment and embodiment 1 is that reagent one, reagent two and samples in this embodiment share a first reagent sample plate 8, the outer ring places samples, the inner ring places reagents, and there is only one multi-needle rotation device For dispensing reagents and samples.

Abstract

The invention discloses a full-automatic biochemical analyzer with a multi-needle alternating device and a full-automatic biochemical analyzing method. The analyzer comprises a reagent disc, a reaction disc, a stirring unit, a sample loading unit, a detection cup washing unit, an optical detection unit, a control and data analysis processing unit and more than one multi-needle alternating device, wherein the multi-needle alternating device comprises a plurality of hollow needles, a valve, a connecting pipeline, a quantitative injector and a needle moving device; the hollow needles are connected with the quantitative injector through the valve and the pipeline respectively; the needle moving device is used for synchronously driving the plurality of hollow needles to synchronously move between a reagent bottle and the detection cup or between a sample cup and the detection cup or among the reagent bottle, the sample cup and the detection cup. According to the full-automatic biochemical analyzer, the problem of a traditional full-automatic biochemical analyzer that crossed pollution of different reagents and sample is caused by the fact that a reagent / sample needle is not washed completely is greatly reduced through the multi-needle alternating device, and the accuracy and reliability of a detection result can be improved.

Description

technical field [0001] The invention belongs to the technical field of medical examination and detection, in particular to a fully automatic biochemical analyzer with a multi-needle rotation device and a method thereof. 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 many different reagents and different samples are often used in the detection, and the instruments all use shared reagent needles and sample needles to draw different reagents and different samples into each test cup To measure. When drawing reagents and samples, the inside and outside of the reagent needles and sample needles, especially the inside of the needles, often remain reagents and samples, and it is difficult to clean them thoroughly. In addition, medical testing instruments are generally required to run at a relatively high speed. Therefore, there...
