Description
Technical Field
The invention belongs to the technical field of detection equipment, and particularly relates to an analysis method of a blood coagulation analyzer and the blood coagulation analyzer.
Background
The blood coagulation analyzer is a special instrument for analyzing thrombus and hemostasis, can detect various thrombus and hemostasis indexes, provides valuable indexes for diagnosis of bleeding and thrombotic diseases, monitoring of thrombolysis and anticoagulation treatment and observation of curative effects, and is the most basic equipment used in a thrombus/hemostasis laboratory at present.
The full-automatic blood coagulation analyzer can support the detection project of the coagulation method. On the basis of the items of detection by the coagulation method, a partial hemagglutination analyzer can also support the items of detection by the immunoturbidimetry and/or chromogenic substrate method.
Two basic detection principles of the coagulation method are the optical method and the magnetic bead method. Compared with an optical method, the magnetic bead method is hardly influenced by abnormal interference substances in the sample, and results can be given to the abnormal sample in time. However, instrument cost and detection cost of the magnetic bead method instrument are generally higher than those of the optical method.
In the prior art, a blood coagulation analyzer based on an optical principle for a partial coagulation detection project adopts a mode of integrating a plurality of wavelengths of detection light at the same detection position, and reduces the interference of a sample aiming at the partial coagulation detection project. In such instruments, the dominant wavelength is selected by default, and is typically the wavelength at which the detection signal has a larger amplitude of change, which is more favorable for the detection sensitivity of the sample. However, when the sample has interfering substances, signals with different wavelengths are affected differently, and if it is determined that the interference on the main wavelength is large, the instrument can automatically switch to the sub-wavelength with the relatively small interference degree of the detection channel for detection.
Because the automatic blood coagulation detection instrument has a plurality of detection positions, part of products adopt a light source + optical fiber light splitting mode to provide multi-wavelength detection light for each detection position. The optical fiber splitting mode brings about the complexity of the instrument and the relatively higher cost of the optical system.
If one LED light source is used for each detection position, the cost of the instrument is relatively lower. If the instrument has at least two detection channels with different wavelengths, the detection channels with different wavelengths can be switched, so that the abnormal interference sample can be detected in time without high-speed centrifugation, blood collection again or recourse to a magnetic bead method with relatively higher detection cost. While the instrument maintains low manufacturing costs.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The embodiment of the invention provides an analysis method of a blood coagulation analyzer, which comprises the following steps: at least one optical transmission channel with a first wavelength, and monochromatic light with the first wavelength is formed by the channel light source and the optical filter; at least one optical transmission channel with a second wavelength, and monochromatic light with the second wavelength is formed by the channel light source and the optical filter; at least one coagulation item, by default, using said first wavelength, and switching to an optical transmission channel of said second wavelength if an anomaly in the signal of said first wavelength is found.
Specifically, a first wavelength of monochromatic light is formed on at least one optical transmission channel and filter of a first wavelength, and a second wavelength of monochromatic light is formed on at least one optical transmission channel and filter of a second wavelength. By default, using the first wavelength, if the signal of the first wavelength is found to be abnormal, the optical transmission channel of the second wavelength is switched to detect. If the signal of the second wavelength is abnormal, the signal can be detected by switching to the first wavelength. The channels with various wavelengths can improve the detection efficiency and are widely used. Therefore, most abnormal samples of the project can be detected in time without high-speed centrifugation, blood re-sampling or recourse to a magnetic bead method with relatively higher detection cost; meanwhile, instrument complexity and relatively higher instrument cost caused by integrating a plurality of detection wavelengths in the same detection channel are avoided.
In this embodiment, if the signal of the first wavelength is found to be abnormal, the same cuvette is switched to the optical transmission channel of the second wavelength. If the signal with the first wavelength is found to be abnormal, the reaction cup originally placed on the detection position on the optical transmission method channel with the first wavelength can be grabbed to the optical transmission method channel with the second wavelength by moving the grabbing hand to detect, the reaction cup switching detection effect is good, and the detection efficiency is higher.
In this embodiment, if the signal of the first wavelength is found to be abnormal, another cuvette is switched to the optical transmission channel of the second wavelength. If the signal with the first wavelength is found to be abnormal, the reaction cup originally placed on the detection position on the optical transmission method channel with the first wavelength can be grabbed to the optical transmission method channel with the first wavelength by moving the grabbing hand to detect, the reaction cup switching detection effect is good, and the detection efficiency is higher.
In this embodiment, if the signal abnormality of the first wavelength and the signal abnormality of the second wavelength are found, the magnetic bead cuvette is moved to the detection site of the magnetic bead method, and detection is performed. If the signals of the first wavelength and the second wavelength are found to be abnormal, the magnetic bead reaction cup can be moved to the detection position of the magnetic bead method for detection. The detection mode is various, and the detection effect is better.
Alternatively, for example, the first wavelength is 405nm, the second wavelength is 660nm, and the other wavelengths are 850 nn. If an abnormal sample happens and cannot be tested due to interference during detection at 405nm, the sample can be switched to a transmission method channel with a second wavelength for detection, and if the signals of the first wavelength and the second wavelength are found to be abnormal, the magnetic bead reaction cup is moved to a magnetic bead method detection position for detection. If the signals of the first wavelength and the second wavelength are found to be abnormal, the magnetic bead reaction cup can be moved to the detection position of the magnetic bead method for detection. The detection mode is various, and the detection effect is better.
