Problems solved by technology

Moreover, in order to take into account the R2 reagent and the R1 reagent, the sampling device can only use the rotating arm device of the existing automatic biochemical analyzer, so that the R1 reagent, the R2 reagent, the sample to be tested and the needle washing mechanism can only be arranged on the circumference of the sampling mechanism. On the trajectory, the volume of the equipment is still restricted by the rotating arm and the refrigeration device, and it is difficult to further miniaturize

Embodiment 1

[0052] Such as figure 1 and figure 2 As shown, when the present invention is applied to a special-purpose small-scale automatic emergency biochemical analyzer, the R1 reagent strip 1 and the R2 reagent 2 (which can be used for a certain biochemical item (such as liver function)) required by the biochemical detection item are required. The packaging method of reagent strips or reagent bottles) are respectively placed in the dedicated positions on the matching special biochemical analyzer. The number of placed R1 reagent strips 1 can vary with the structure size of the supporting instrument, and the number of sample placement positions can also be set. Increase or decrease accordingly.

[0053] The sample position 2, the cleaning position 3, and the R2 reagent 2 are all located on the trajectory formed by the rotation of the injection needle mechanical arm 5, while the R1 reagent strip 1 adopts a crescent-shaped combination of multiple reagents, and its rotation trajectory has...

Embodiment 2

[0058] The present invention is also applicable to Figure 5 structure shown. R1 reagent strip 1 is still in the form of multiple reagents combined into a crescent-shaped reagent strip. On a turntable, the measurement and analysis mechanism composed of light source 8, photoelectric converter 7, signal amplifier 6, and CPU passes sequentially, and the mechanical arm 10 of the sampling mechanism Move up and down, left and right along the moving track 9, and move in a straight line to realize the functions of sample addition and R2 reagent addition. The sample position 3 , the cleaning position 4 and the R2 reagent 2 can be arranged at any position on the movement track of the mechanical arm 10 .

Abstract

The invention discloses a clinical chemistry integrated and combined multi-reagent-strip detection device and method. The detection device comprises reagent strips, sampling needles, an optical detection system and a displacement device, the sampling needles are installed on the displacement device, each reagent strip is provided with multiple reagent cavities which are connected in parallel into a whole body, and the reagent cavities are located on the movement track of the displacement device. The method comprises the steps of sample suction, R1 reaction, R2 adding, colorimetric analysis, needle cleaning and the like. According to the clinical chemistry integrated and combined multi-reagent-strip detection device and method, the reagent strip structure that the multiple reagent cavities are connected in parallel, the detection procedure can be simplified, an automatic analyser can be compact in structure and high in reliability, and the detection for a small batch of samples is accelerated.

Description

technical field [0001] The invention relates to a clinical chemistry integrated multi-combination reagent strip detection method and its related mechanism, which can be matched with a special biochemical analysis instrument using colorimetry and used for biochemical detection of clinical samples. Background technique [0002] The automatic biochemical analyzer is an instrument for measuring a specific chemical composition in body fluids based on the principle of photoelectric colorimetry. Because of its fast measurement speed, high accuracy, and small consumption of reagents, it has been widely used in hospitals at all levels. Existing fully automatic biochemical analyzers usually use a dual reagent method: before detection, add the first reagent (commonly known as R1 reagent in the art) to make it react with the interfering substances in the sample; add the second reagent (reagent in the art) Commonly known as R2 reagent), formally react with the sample. In order to meet ...
