An embodiment of the present invention provides a water blank detection method, and referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the water blank detection method according to the present invention.

In this embodiment, the water blank detection method includes the following steps:

step S10: in the n-step cleaning process of the reaction cup, the water blank value of the reaction cup after each step of cleaning is obtained, wherein n is more than or equal to 3.

It should be understood that n represents a constant of 8, after the reaction cup is used, 8 washing steps are required, water blank detection is required for the reaction cup after each washing step is finished, and the water blank value of the reaction cup after the first 6 washing steps is taken for detection in the embodiment.

In this embodiment, as shown in fig. 3, 1 denotes a light source lamp, which provides a light source for the device for detecting the water blank value of the reaction cup; 2 is a reaction cup, and the reaction cup is filled with liquid; 3, an optical detection module which receives the light passing through the reaction cup, detects the light intensity signal and converts the light intensity signal into a water blank value; and 4, an automatic cleaning needle is used for cleaning the reaction cup, and water is injected into the reaction cup through the automatic cleaning needle. The light source lamp is fixed on one side of the reaction cup, light generated by the lamp is emitted through the reaction cup, and the optical detection module is arranged on the other side of the reaction cup; the automatic cleaning needle is arranged right above the reaction cup and can vertically descend into the reaction cup for cleaning.

In specific implementation, the light source lamp is turned on, the automatic cleaning is performed on the reaction cup (total 8 steps), the reaction cup rotates after every 1 step is cleaned, the rotation process finishes photometry through the optical detection module, the optical detection module detects a light intensity signal of light passing through the reaction cup by receiving the light, and the light intensity signal is converted into a water blank value (AD signal value), so that the water blank value of the reaction cup at each step is obtained.

Step S20: and selecting a target water blank value from the water blank values.

In the present embodiment, the target water blank value refers to the measured water blank value of the 6 th order.

It should be understood that after each reaction cup is cleaned by 8 stages, the cup is an empty cup to be measured; in the process of cleaning the reaction cup, water/cleaning liquid is filled in the cup after the first 6-stage cleaning, and the water blank value of the reaction cup is detected by taking the water blank value after the 6 th-stage cleaning and carrying out correlation comparison, so that the detected water blank value is more accurate.

Step S30: comparing the target water blank values with comparison water blank values among the water blank values, respectively.

The comparative water blank values refer to the water blank values of the 4 th and 5 th stages after the cuvette was washed.

It should be understood that, during the 1 st and 2 nd cleaning, in order to clean the reaction cups, the cleaning liquid used is alkaline cleaning liquid, so that a large amount of alkaline cleaning liquid remains in the reaction cups of the 1 st and 2 nd stages, and air bubbles are attached to the reaction cups, so that the measured water blank value is not accurate enough, while during the 3 rd and subsequent cleaning, the reaction cups are cleaned by water, after the 3 rd cleaning, a small amount of alkaline cleaning liquid remains in the reaction cups, so that the AD value is not accurate enough, and during the 4 th and 5 th cleaning, the cleaning liquid is water, and the AD value after cleaning gradually approaches the AD value of the 6 th stage.

In this embodiment, the AD values measured after the 4 th and 5 th cleaning of the cuvette were selected as comparison targets to be compared with the AD value of the 6 th order.

Step S40: and judging whether the target water blank value of the reaction cup is abnormal or not according to the comparison result.

It is understood that comparing the AD value of the 6 th order with the AD values of the 4 th and 5 th orders, respectively, results of the comparison, and comparing the result of the comparison with a normal threshold value to determine whether the water blank value is abnormal, and using the water blank value of the 6 th order as a final reaction cup water blank value.

In specific implementation, when the water blank value is judged to be abnormal according to the comparison result, the reaction cup is skipped over for testing and does not participate in subsequent calculation, and when the water blank value is judged to be normal according to the comparison result, the AD value of the 6 th order is taken as the water blank value of the reaction cup and participates in the subsequent calculation.

In the embodiment, a water blank value of a reaction cup after each step of cleaning is obtained in the n-step cleaning process of the reaction cup, wherein n is more than or equal to 3; selecting a target water blank value from the water blank values; comparing the target water blank values with comparison blank values of the water blank values, respectively; judging whether the target water blank value of the reaction cup is abnormal or not according to the comparison result; the water blank value of the target order is selected to be compared with the comparison water blank value, and water blank detection is carried out according to a comparison mode, so that the detection result is not influenced by bubbles, and the detection result is more accurate.

Referring to fig. 4, fig. 4 is a schematic flow chart of a water blank detection method according to a second embodiment of the present invention.

Based on the first embodiment, the step S40 of the water blank detection method in this embodiment specifically includes:

step S401: comparing the comparison result with a normal threshold.

It should be understood that the comparison results refer to a1 comparison result of the AD6 of the 6 th order with the AD4 of the 4 th order and a2 comparison result of the AD6 of the 6 th order with the AD5 of the 5 th order, and a1 is AD6/AD4, and a2 is AD6/AD 5.

In a specific implementation, the normal threshold refers to 99%; and comparing the comparison result with 99% respectively, and judging whether the water blank value of the reaction cup is normal according to the result after comparison.

Step S402: and when the comparison results are all larger than or equal to the normal threshold value, determining that the target water blank value of the reaction cup is normal.

It should be noted that, the comparison result being equal to or greater than the normal threshold means that the percentage of the values of a1 and a2 is greater than 99%, and when both of the two sets of conditions are satisfied, the water blank is judged to be normal.

It is understood that when bubbles are attached to the cuvette, the measured water blank value of the cuvette may become small or abnormal, and the normal water blank value gradually approaches the normal water blank value as the number of washing steps increases, so that AD4 and AD5 gradually approach AD6 in the normal case. For example, if the measured AD6 value is 2000, AD5 is 1999, AD4 is 1980, then A1> 99% and A2> 99%, then the water blank value is judged to be normal.

Correspondingly, after the target water blank value of the reaction cup is determined to be normal, the method further comprises the following steps: and taking the target water blank value as a reference water blank value.

It is to be understood that the reference water blank value refers to a water blank value of the cuvette which is finally used for subsequent calculations, and when the AD6 value of the cuvette is determined to be normal, the subsequent calculations are performed with the value of AD6 as the reference water blank value of the cuvette.

In the specific implementation, as shown in fig. 5, fig. 5 is an overall flow of water blank determination, and after determining that the water blank is normal according to the comparison result, the water blank value AD6 of the 6 th order is taken as the water blank value of the reaction cup to participate in the subsequent calculation.

Further, after the step of comparing the comparison result with a normal threshold, the method further includes: and when the comparison result is smaller than the normal threshold value, determining that the target water blank value of the reaction cup is abnormal.

It is understood that when one of a1 and a2 is less than 99%, it indicates that the AD6 value at this time is abnormal, and it is judged that the water blank value at this time is abnormal. For example, if the detected AD4 is 800, the AD5 is 801, and the AD6 is 700, then a1< 99%, a2< 99%, and AD6 are abnormal, and the water blank is determined to be abnormal.

When it is determined that the reaction cuvette is abnormally empty, the sample addition test is skipped for the reaction cuvette.

The embodiment compares the comparison result with a normal threshold value; when the comparison results are all larger than or equal to the normal threshold value, determining that the target water blank value of the reaction cup is normal; comparing the water blank value of the reaction cup after the 6 th-order cleaning with the water blank value of the reaction cup after the 4 th-order cleaning and the water blank value of the reaction cup after the 5 th-order cleaning respectively to obtain a compared numerical result, comparing the compared numerical value with a normal threshold value for the second time respectively, determining that the water blank of the reaction cup is normal when the compared numerical results are all larger than or equal to the normal threshold value, taking the water blank value of the 6 th order as the water blank value of the reaction cup, and participating in subsequent calculation; and when at least one of the compared numerical results is smaller than the normal threshold, determining that the water blank of the reaction cup is abnormal, skipping the test on the reaction cup, removing the abnormal water blank value, and participating in subsequent calculation, thereby avoiding the influence on the result of the clinical test due to the water blank abnormality.

Referring to fig. 6, fig. 6 is a schematic flow chart of a water blank detection method according to a third embodiment of the present invention. Based on the first embodiment, the step S10 of the water blank detection method of this embodiment specifically includes

Step S101: and after each step of cleaning is carried out on the reaction cup, obtaining a light intensity signal penetrating through the reaction cup.

It should be noted that, after the reaction cup is cleaned at each step, the reaction cup is rotated, the light source lamp is fixed at one side of the reaction cup, light generated by the light source lamp passes through the reaction cup, and the optical detection module detects a light intensity signal transmitted through the reaction cup during the rotation process.

In specific implementation, when bubbles are generated and attached to the inner wall of the reaction cup in the cleaning process of the reaction cup, the detection of the light intensity signal penetrating through the reaction cup becomes small or abnormal, while the 1 st-order cleaning and the 2 nd-order cleaning use alkaline cleaning liquid, a large amount of bubbles are likely to be attached to the inner wall of the reaction cup, the light intensity signal at the moment becomes small, and the measured water blank value of the reaction cup is inaccurate.

Step S102: and determining the water blank value of the reaction cup after each step of cleaning according to the light intensity signal.

It should be understood that, when the light intensity signal transmitted through the cuvette is detected, the light intensity signal is converted into an AD signal value, and a water blank value of the cuvette after each step of washing is obtained.

Further, after obtaining the water blank value of the reaction cup after each step of cleaning, selecting the water blank value of the 6 th step to compare with the comparison water blank value, and then determining the comparison water blank value: acquiring a cleaning order corresponding to the target water blank value; determining a corresponding target cleaning solution according to the cleaning order; and selecting a water blank value with a cleaning order consistent with the target cleaning liquid from the water blank values as a comparison water blank value.

It should be understood that the target cleaning fluid refers to water and the comparative water blank value refers to a 4 th order water blank value and a 5 th order water blank value.

In specific implementation, in order to clean the reaction cup and leave no pollutant in the reaction cup, the 1 st and 2 nd order cleaning reaction cups use alkaline cleaning liquid, the alkaline cleaning liquid contains a large amount of bubbles, the AD values measured by the 1 st and 2 nd orders are abnormal, the reaction cups are cleaned by using water from the 3 rd to 6 th orders, and the AD values measured by the 4 th and 5 th orders are taken as comparison water blank values considering that the reaction cups cleaned by the 3 rd order may have a small amount of residual alkaline cleaning liquid.

It should be noted that, by determining the 6 th-order cleaning solution and cleaning solutions of other orders, a water blank value of an order consistent with the 6 th-order cleaning solution is searched for, so as to obtain a 3 rd-order water blank value, a 4 th-order water blank value and a 5 th-order water blank value, and if a little alkaline cleaning solution remains in the 3 rd order, the 4 th-order and 5 th-order water blank values are used as comparison water blank values. And obtaining the AD value of the 4 th order and the AD value of the 5 th order by obtaining the light intensity signal of the 4 th order and the light intensity signal of the 5 th order.

In the embodiment, after each step of cleaning is carried out on the reaction cup, a light intensity signal penetrating through the reaction cup is obtained; determining the water blank value of the reaction cup after each step of cleaning according to the light intensity signal; the light intensity signal of the reaction cup after each step of cleaning is obtained and converted into an AD signal value, a 1-6-step water blank value is obtained, and a 5 th-step AD value and a 4 th-step AD value which are gradually close to the 6 th-step AD value are used as comparison water blank values, so that an accurate AD comparison value is provided for subsequent water blank detection.
