Description

Technical Field

[0001] This utility model relates to the field of veterinary testing equipment technology, specifically to a chicken pullorum detection device. Background Technology

[0002] Pullorum disease (African pullorum infection) is a common infectious disease caused by Salmonella pullorum, posing a significant threat to the poultry industry. Infected chickens exhibit symptoms such as stunted growth, lethargy, and diarrhea, severely impacting their growth, development, and productivity. Furthermore, the bacteria can be vertically transmitted through eggs, causing the disease to be passed down through generations. Timely and accurate detection of pullorum-infected chickens is crucial for controlling outbreaks and minimizing economic losses in poultry farms.

[0003] Current methods for detecting pullorum disease in chickens often use ordinary glass plates under natural light, which has the following drawbacks: Temperature sensitivity: The NY / T536-2017 standard requires a reaction temperature of 20-25℃, but existing equipment lacks a constant temperature system, making it difficult to meet the standard in winter. Light interference: Relying on natural light, it is easily affected by changes in ambient brightness, and direct artificial light sources can cause glare interference. Risk of cross-contamination: The efficiency of cleaning and disinfecting the glass plates is low during continuous testing, and improper wastewater treatment can easily lead to the spread of pathogens. Insufficient portability: Traditional equipment has a fixed power supply, which cannot meet the needs of mobile testing in chicken houses.

[0004] Therefore, it is necessary to propose a detection device for fowl pullorum disease. Utility Model Content

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Pullorum disease is an infectious disease in poultry caused by Salmonella Pullorum, and its diagnosis relies on serological agglutination reactions. According to the NY / T 536-2017 standard, "Diagnostic Techniques for Fowl Typhoid and Pullorum," the test must be conducted at an ambient temperature of 20-25℃, and the antigen-antibody reaction results must be observed under natural light. However, traditional detection methods have the following technical bottlenecks:

[0031] Unstable temperature control: In winter, the ambient temperature is difficult to meet the detection requirements, resulting in a decrease in reaction sensitivity;

[0032] Light source interference: Color temperature deviation of artificial light sources can easily cause misjudgment of agglomerated particles;

[0033] Risk of cross-contamination: Incomplete cleaning and disinfection of reused test carriers may lead to the spread of pathogens;

[0034] Low operational efficiency: The equipment is inconvenient to move and the management of consumables is chaotic, making it difficult to meet the rapid screening needs of large-scale farms.

[0035] This technical solution integrates constant temperature control, optical simulation, closed-loop waste liquid treatment, and portable design to construct a standardized and high-precision chicken pullorum detection system, which significantly improves detection efficiency and result reliability.

[0036] Technical principles and functional implementation

[0037] 1. Constant temperature control technology

[0038] Based on a PID (Proportional-Integral-Derivative) closed-loop control algorithm, an intelligent temperature control module powered by low-voltage DC power is used to monitor the temperature of the reaction area in real time via a high-precision temperature sensor. When the ambient temperature is below 20℃, the system automatically activates the heating function to stably control the temperature of the detection area within the range of 20-25℃ (error ≤ ±0.5℃). Deionized water or a specific electrolyte is used as the heating medium, ensuring uniform temperature distribution on the detection platform through uniform heat conduction, thus solving the problem of insufficient reaction activity in low-temperature environments during winter.

[0039] 2. Optical inspection technology

[0040] To address the issue of dependence on natural light, a full-spectrum simulated light source system was developed:

[0041] Light source selection: 4500K color temperature LED array, color rendering index (CRI) ≥90, spectral range covering 400-700nm, matching degree with natural light spectrum of over 95%;

[0042] Optical optimization: The diffuse reflector is used to scatter light, eliminating glare interference caused by direct light. At the same time, a white-based frosted detection platform is configured with a surface roughness controlled at Ra0.4-0.8μm, which improves the contrast of the blue agglutinated particles formed by the antigen-antibody reaction by more than 2 times and significantly reduces the error of visual interpretation.

[0043] 3. Pollution prevention and wastewater treatment technologies

[0044] Closed-loop wastewater recycling: After testing, the high-temperature sterilized wastewater is directly introduced into a sealed waste container through a negative pressure siphon device to avoid operators coming into contact with contaminants;

[0045] High-temperature disinfection mechanism: Supports rinsing the testing platform with boiling water at 85-100℃ for more than 10 minutes, effectively inactivating Salmonella and blocking horizontal transmission routes;

[0046] Consumables are managed in separate compartments: test reagents, cleaning tools and other consumables are stored in separate sealed compartments to prevent cross-contamination.

[0047] 4. Portability and rapid testing technology

[0048] Mobile power supply system: Built-in high-capacity lithium-ion battery pack, full-load battery life ≥8 hours, supports continuous operation in chicken coop environment without external power supply;

[0049] Modular design: The detection platform, temperature control module, and light source system are independently packaged, supporting quick disassembly and maintenance. A single complete detection process takes ≤3 minutes, suitable for screening needs of flocks of thousands of chickens per day.

[0050] Core functional modules

[0051] 1. Intelligent temperature control system

[0052] Temperature adaptive adjustment: Built-in ambient temperature sensor automatically calculates heating power requirements, and can still raise the detection area to 20℃ within 30 minutes in extreme low temperature (-5℃) winter environments;

[0053] Multi-level safety protection: Overload current protection, automatic power-off when dry burning, and abnormal high temperature alarm are triple protection mechanisms to ensure safe operation of the equipment.

[0054] 2. Optical determination system

[0055] Dynamic light intensity compensation: Automatically adjusts the LED output brightness according to the ambient light intensity to maintain the optimal observation illuminance of 2000-3000 lux;

[0056] Assisted judgment mode: Optional portable microscope interface, supporting 40-100x magnification for observation of micron-sized aggregated particles.

[0057] 3. Waste liquid treatment system

[0058] Wastewater is stored in a tiered manner: highly polluted wastewater containing pathogens is separated from ordinary clean wastewater for separate treatment, in accordance with the Biosafety Level 2 (BSL-2) standard.

[0059] Standardized operating procedures

[0060] 1. Preparation before testing

[0061] Start the equipment and complete the self-test to confirm that the temperature and light source systems are operating normally.

[0062] Remove the standard antigen for pullorum disease from the cold storage, allow it to equilibrate to 20°C, and then shake to mix thoroughly.

[0063] Use a special crayon to divide the detection platform into 2×2cm reaction grids and mark the sample numbers.

[0064] 2. Sample Collection and Response

[0065] Suitable for chickens aged 3 months and older.

[0066] Set up strong positive, weak positive and negative serum controls (1 drop each). Add 1 drop of antigen to each control and mix well. Within 2 minutes, the strong positive serum should show 100% agglutination, the weak positive serum should show 50% agglutination, and the negative serum should not agglutinate.

[0067] Using a dropper, draw up the antigen and drop 1 drop (equivalent to 0.05 ml) vertically onto a glass plate. Then, puncture the chicken's brachial vein or comb tip with a needle to collect 0.05 ml of blood (equivalent to two full rings of blood in a 7.5-8.0 mm inner diameter metal wire ring). Mix the blood with the antigen and spread it out to form a liquid surface with a diameter of about 2.0 cm.

[0068] The operation is carried out by two people: one person restrains the chickens, and the other person collects blood, spreads it, and makes a judgment.

[0069] After standing for 2 minutes, proceed to the result determination stage.

[0070] 3. Result Determination and Recording

[0071] Observe agglutination under simulated natural light: determine the result within two minutes. Agglutination of 50% (++) or more is positive; no agglutination is negative; anything in between is questionable.

[0072] Positive reaction: The appearance of obvious blue granular or flocculent aggregates;

[0073] Negative reaction: The liquid remains in a uniform emulsion state;

[0074] By capturing reaction images using wireless terminals (tablets / phones), the AI-assisted analysis system automatically generates a judgment report with an accuracy rate of ≥98%.

[0075] 4. Cleaning and Maintenance

[0076] After a single batch of testing is completed, boiling water is poured into the testing platform to immerse it, and the platform is left to stand for 10 minutes to inactivate the pathogens.

[0077] Initiate the waste liquid recycling process to centrally process the wastewater into biosafety bags;

[0078] Wipe the operating interface with 75% alcohol wipes and disinfect the chamber with ultraviolet light for 30 minutes.

[0079] Technological advantages and innovations

[0080] Breaking through the limitations of traditional water bath heating, this method combines medium conduction with intelligent algorithms to achieve a dual improvement in temperature uniformity and stability in the testing area, increasing the winter testing pass rate from 72% to 98% compared to traditional equipment.

[0081] The combination of full-spectrum simulation and reflectance enhancement technology enables the color contrast of the agglutination reaction to reach the optimal threshold for manual interpretation, reducing the false judgment rate to below 2% and meeting laboratory-grade testing standards.

[0082] The entire chain of pollution prevention mechanisms, from isolated storage of consumables and high-temperature sterilization to sealed treatment of waste liquid, effectively blocks the spread of pathogens, and the cross-contamination rate during equipment reuse is ≤0.1%.

[0083] The lightweight design and long-lasting power supply system enable the equipment to be quickly moved between multiple buildings in the farm, improving the detection efficiency by more than 3 times compared to fixed equipment.

[0084] Application scenarios and scalability

[0085] This equipment is suitable for on-site screening in breeding farms, commercial layer chicken farms, and poultry quarantine agencies, and its functions can be expanded in the following ways:

[0086] IoT integration: Adding environmental sensors and 5G modules enables real-time uploading of detection data to the aquaculture management system;

[0087] Standardized output: Generates electronic test reports that comply with OIE (World Organisation for Animal Health) standards, supporting cross-border quarantine certification.

[0088] This technological solution addresses key challenges in traditional fowl typhoid detection through technological innovation, providing standardized and intelligent tools to support poultry disease prevention and control.
