Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, specifically to an instrument and working method for morphological and dry chemical testing. Background Technology

[0002] Morphological examination is a technique that involves directly observing the morphology, structure, and staining characteristics of samples such as blood, body fluids, tissues, and cells under a microscope or through image analysis to diagnose and differentiate diseases. Existing equipment includes automated blood cell analyzers and urine sediment analyzers, which utilize technologies such as flow cytometry and digital imaging to achieve high-speed, automated morphological screening. It is intuitive, highly specific, and can detect abnormal cells and structures that automated instruments cannot identify.

[0003] Dry chemistry assays involve directly adding liquid biological samples (such as serum, plasma, and urine) onto chemical reaction reagents fixed to a special carrier (such as test strips or reagent sheets). The concentration of specific chemical components in the sample is determined by detecting color changes, among other things. A quantitative sample (serum / urine / whole blood) is added to a reagent card. The liquid sample permeates the layers, dissolving the dried reagents and triggering specific enzymatic or chemical reactions (such as redox reactions or coupling reactions). The reaction produces a color change, the intensity of which is directly proportional to the concentration of the analyte. The analyzer uses reflectance spectrophotometry to measure the reflectance of a specific wavelength of light on the reagent sheet, thereby calculating the concentration of the analyte.

[0004] In clinical laboratory testing, morphological and dry chemical detection items are typically performed using separate instruments for each item. This requires numerous instruments and equipment, occupies significant space, wastes human and financial resources, and relies on visual observation and judgment by operators, resulting in poor instrument accuracy. Therefore, it is necessary to design an instrument and method for both morphological and dry chemical detection to address the problems of incompatible instruments, wasted human and financial resources, and poor accuracy in existing technologies.

The nature of the specimen and the test items have been determined according to the patient information. The scanning module identifies and confirms the nature of the specimen again based on the internal input information, identification ID and external characteristics of the specimen box, and determines the specimen test items.

[0023] S2. Based on the obtained detection content, the card chamber operation system pushes out the required disposable counting cells and dry chemical detection cards onto the card conveyor belt at fixed positions according to the detection items.

[0024] S3. The card conveyor belt transports the disposable counting cell and dry chemical test card to the sample addition position for sample addition;

[0025] S4. The sampling needle moves through a horizontal lifting power structure.

[0028] S7. After sedimentation, the solid components of the dry chemical test card or disposable counting cell are stabilized and automatically pushed under the microscope. The microscope stage automatically moves the field of view, and the microscope automatically focuses to record and photograph the solid components. The video and photos are then sent to the automatic image analysis system to automatically screen the results and generate a test report.

[0029] S8. After the report is issued, the instrument will transfer the waste dry chemical test card or disposable counting cell to the waste box.

[0030] The present invention has the following beneficial effects:

[0031] The morphological and dry chemical detection instruments and working methods designed in this invention replace the detection of different specimens by several instruments with one instrument, and replace the functions of these instruments.

[0058] 1. The test tube rack 501 is placed in the test position, and different specimen boxes 502 are placed on the test tube rack 501. The nature of the specimen and the test items have been determined according to the patient information.

[0059] 2. Based on the obtained detection content, the card chamber operation system 1 pushes out the required disposable counting cells and dry chemical detection cards onto the card conveyor belt 3 at fixed positions according to the detection items.

[0060] 3. Card conveyor belt 3 transports the disposable counting chamber and dry chemical test card to the sample addition position to await sample addition.

[0061] 4. The sampling needle 601 moves via a horizontal lifting power structure. As required, the sampling needle 601 moves to the designated sample application hole 614, descends, and enters the designated specimen box 502. Depending on the specimen requirements, it determines whether to add diluent, mixes the specimen, and aspirates the sample. Then, it rises to the designated position to perform one-time counting cell sampling and dry chemical test card sampling. After sampling, the sampling needle 601 automatically moves to the rinsing box 504 along the designated route for internal and external cleaning procedures.

[0062] 5. After adding the sample, the instrument automatically pushes the dry chemical test card or disposable counting cell into the waiting area to allow the precipitation of the formed components in the disposable counting cell. After a certain period of time, the dry chemical test card or disposable counting cell is pushed into the microscope 701.

[0063] 6. Dry chemical testing: Immediately after the sample is added, the spectrometer 13 performs semi-quantitative dry chemical testing on the sample according to the specified requirements, inputs the information into the report, and the camera 2 8 takes pictures of the dry chemical results for preservation. After automatic analysis, the results are reported to the result processing system and a test report is generated.

[0064] 7. After sedimentation, the tangible components of the dry chemical test card or disposable counting cell are stabilized and automatically pushed under the microscope 701. The microscope stage 702 automatically moves the field of view, and the microscope 701 automatically focuses to record and photograph the tangible components. The video and photographs are then sent to the automatic image analysis system to automatically screen the results and generate a test report.

[0065] 8. After the report is issued, the instrument will transfer the waste dry chemical test card or disposable counting cell to the waste box.

[0066] The instrument is equipped with a reagent addition pump and a pneumatic mixing pump to complete the dilution and mixing of different samples. One instrument replaces several instruments for the testing of different samples; that is, any sample requiring morphological or dry chemical testing can be tested. Specifically, specimen boxes with identical exteriors but different interiors are placed on the same test tube rack 501. Based on the input of different patient testing information, the instrument automatically determines the operating procedure according to the unique identification information of the specimen box 502, thus saving on instrument purchase costs and reducing the need for operators.
