Technical Field

The present invention relates to a sample testing apparatus, and more particularly to a fully automatic testing apparatus for testing the concentration of a sample to continuously analyze a large number of samples without interruption.

Background

An analyzer for clinical examination is generally used for qualitative and quantitative measurement of a specific component in a biological sample such as blood or urine. In a general operation of an analyzer, a sample container is first dispensed into a reaction container through a sample nozzle. Further, a reagent is dispensed from a reagent container into a reaction container into which a sample is dispensed through a reagent nozzle, and the reagent is stirred. Then, the reagent and the specimen in the reaction container are allowed to react for a predetermined time to form a reaction solution. Then, the reaction solution is detected, and the concentration is calculated from the detection results, for example, information such as the absorbance and the luminescence amount.

In recent years, in order to prevent a medical accident, that is, a reagent container is filled incorrectly and/or a reagent container of another item is installed at a place where the reagent container should be installed, which may cause a subsequent measurement error, damage to a specimen sample and an error in measurement information of the specimen sample, which may easily cause a medical misdiagnosis or medical negligence. Therefore, in order to improve the above-mentioned deficiency, the traceable label such as a barcode can be used for each reagent container, and the reagent is used in a disposable manner so as to prevent the reagent from being deteriorated or deteriorated even if the reagent is stored for a long time, and so as not to add the reagent to the used reagent.

Generally, after a batch of sample samples is measured, an operator calculates the amount of reagent required for the next batch of sample samples, and sets the calculated amount in the analyzer. Sometimes, a plurality of reagents are used for each item, and therefore, it takes much labor and time to confirm the amount of the reagents used and to set the reagents in the analyzer. In addition, in order to use the replaced reagent container for actual inspection, it is necessary to create a calibration curve for each reagent container to confirm whether or not the reagent in the reagent container can be inspected.

Please refer to fig. 4. FIG. 4 is a flow chart illustrating the operation steps of the fully automatic inspection apparatus. In describing the operation procedure flowchart of fig. 4, the description will be made with reference to fig. 1, fig. 2, fig. 3A, and fig. 3B. Step 902: and starting the reaction cup transfer frame, taking a certain number of cuvettes from the reaction frame, and placing the cuvettes on the reaction disc. In this step, the user needs to put the reaction racks 10 carrying the cuvettes 102 on the reaction rack transport mechanism 12 in advance, and in the embodiment of the present invention, the reaction racks 10 carrying the cuvettes 102 are usually provided directly by the manufacturer, and of course, the user can fill the reaction racks by himself, but the latter is labor-consuming and time-consuming for the user, and generally the manufacturer provides the reaction racks 10 already containing the cuvettes 102 and uses the reaction racks directly.

Then, in step 904, the sample arm is activated to take the sample of the specimen in the sample tube 402 on the sample injection mechanism and place the sample in the cuvette on the reaction tray. In this step, a pipette 422 is connected to the sample arm 42 to pipette the sample in the sample tube 402, and the sample arm 42 transfers the sample to be injected into the cuvette 102.

And 908, starting a stirring arm to stir the reaction liquid in the cuvette on the reaction disk by using a stirring rod so that the reagent and the sample are reacted and uniformly mixed. This step is optional, but in order to allow the reagent and the specimen to react completely and to be mixed uniformly, this step is still performed in the present invention, the stirring time of the stirring rod 802 in the cuvette 102 is about 1-3 seconds, and because the diameter of the cuvette 102 is not large, the problem that the solution in the cuvette 102 will overflow when the stir bar 802 is received in the cuvette 102 is also considered, thus, the stir bar 802 does not extend entirely into the cuvette 102, only a portion of the stir bar 802 extends into the cuvette 102 to contact the solution, then stirring is carried out at a stirring speed of low rotation speed, and the purpose of the stirring speed of low rotation speed in the step is to avoid too high stirring speed, thereby spraying the reaction solution in the cuvette 102 and preventing the stirring rod 802 from colliding with the cuvette 102 to cause the cuvette 102 and/or the stirring rod 802 to be broken or broken.

And 910, detecting the brightness of the reaction liquid in the cuvette by using a detection unit positioned below the reaction disc, and outputting the detection result. In this step, the cuvette 102 containing the reaction solution is illuminated by the photometric light source (not shown) of the detecting unit 70 to obtain the absorbance of the reaction solution, and the absorbance of the sample is calculated and converted into concentration by the computing module (not shown) of the detecting unit 70, wherein the concentration can be the concentration of nucleic acid or protein. And the calculated concentration value may be outputted via an output device (not shown in the figure) connected to the fully automatic detector 1. Specifically, the output device is connected to the detecting unit 70, and the output device includes a printer, an external storage device, a calculator or a server.

Then, in step 912, the cuvette transfer arm is started to extract the cuvette with the detected absorbance and place the cuvette in a waste liquid recycling bin for collection. In this step, after the reaction liquid in the cuvette 102 on the reaction tray 20 has been subjected to the measurement of the absorbance, the cuvette transfer arm 14 is moved toward the upper side of the reaction tray 20 and grips the cuvette 102 having been subjected to the measurement of the absorbance, and the cuvette 102 containing the reaction liquid is placed in a waste liquid collection tub (not shown).

Therefore, the fully automatic measuring apparatus 1 can perform the operations of repeating the steps 902 to 912, and can perform the operations of fully automatically, massively and continuously outputting the detection results regardless of the sample, the reagent, the cuvette 102, the reaction solution, the detected cuvette 102 and the detection result, thereby saving the labor and reducing the possibility of cross contamination of the sample caused by manual operations.

Optionally, in another embodiment of the present invention, a step 905 is added between step 904 and step 906: the absorbance of the specimen sample (to which the reaction solution has not been added at this time) in the cuvette 102 is detected by a detection unit located below the reaction disk, and blank absorbance data of the specimen sample is obtained. The detecting unit 70 further includes a storage module (not shown in the figure), and the storage module stores a preset blank luminance threshold. The operation module (not shown in the figure) in the detection unit 70 compares the detected blank absorption luminance data with a blank absorption luminance threshold, determines whether the blank absorption luminance data of the sample exceeds a preset blank absorption luminance threshold, and outputs the result via an output device (not shown in the figure) connected to the fully automatic detector 1. The detection personnel are helped to judge, abnormal detection samples are eliminated, and the accuracy of the detection result is further improved.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention; while the invention has been described with reference to exemplary embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
