[ technical field ] A method for producing a semiconductor device

The invention relates to the technical field of mastitis detection, in particular to an mastitis detection analyzer.

[ background of the invention ]

Mastitis, also known as acute mastitis, milk jaundice and milk swelling, is caused by blood stasis and toxic gas condensing on breasts to form carbuncle swelling, and the breasts are hard, swollen, hot and painful, which are commonly seen in postpartum lactation animals, especially in lactation cows, and are commonly seen in livestock in cows and dairy goats; horses and sheep also occur. Taking a cow as an example, mastitis causes huge economic loss to the dairy industry all over the world, the yield and the quality of dairy products are reduced, and the economic loss caused by the mastitis exceeds 100 billion dollars every year. The key to controlling this disease is to achieve rapid and accurate detection of the disease to ensure effective implementation of preventive and therapeutic measures.

Three types of detection instruments which are mainstream in the market at present are a somatic cell count detector, a California mastitis test device and an electric conductivity detector. However, none of the three test foods can completely meet the test requirements of dairy enterprises and dairy farmers. The somatic cell number detector needs long period of detecting somatic cells in a laboratory, and delays the detection and prevention of mastitis. The california mastitis test apparatus requires a small test of about six minutes, requires time-consuming waiting and is inconvenient. The conductivity detector is easily affected by a plurality of environmental factors, thereby causing certain errors. Therefore, how to perfect and solve the problem of the mastitis detection instrument has important practical value. Meanwhile, the majority of users are farmer households, so that a simple and easy-to-use detector is needed to be designed.

The flow guide device 221 prevents interference of bubbles or foam in the sample detection process, thereby improving the detection accuracy. Specifically, in one embodiment, the diversion device 221 is made of food-grade stainless steel.

The temperature sensor 30 is configured to sense a temperature of the sample to obtain a sample temperature of the sample, and send the sample temperature data to the operation module 10; specifically, the temperature sensor 30 is connected to the conductivity detection probe 22 to measure the sample temperature of the sample, and the temperature sensor 30 is connected to the operation module 10 to send the sample temperature data to the operation module 10.

The operation module 10 is used for calculating the received sample conductivity and the sample temperature through a detection algorithm, and for performing detection analysis on mastitis of the sample through the detection algorithm. Specifically, in an embodiment, the operation module 10 includes a microprocessor 11, and the microprocessor 11 specifically performs an operation of a detection algorithm.

The detection algorithm run by the operation module 10 of the mastitis detection analyzer is as follows:

when the following conditions are satisfied: when Ei-aTi < ═ b, the mastitis detection result is normal;

when the following conditions are satisfied: aTi + b < Ei < cTi + d, the mastitis test result is suspected infection;

when the following conditions are satisfied: when Ei-cTi > -d, the mastitis detection result is infection;

wherein Ti is the sample temperature, Ei is the sample conductivity, a and c are slopes, b and d are intercepts, the slopes and intercepts are obtained by measuring the conductivity of a certain number of normal and abnormal samples under different temperature conditions, and by linear fitting, an equation of the sample conductivity at different temperatures is established for calculation; specifically, the error of the conductivity of the sample is calibrated through different temperatures so as to realize accurate detection.
