Description

Technical Field

[0001] This utility model relates to the field of dairy cow mastitis detection technology, specifically a portable device for rapid detection of dairy cow mastitis. Background Technology

[0002] Bovine mastitis is a common inflammatory disease in dairy farming, primarily caused by bacterial infection or physical injury leading to inflammation of the mammary glands. It not only reduces milk production and deteriorates milk quality (e.g., the appearance of clots, off-odors, and abnormal composition), but can also trigger systemic infections, increasing farming costs and culling rates, significantly impacting the economic benefits of the dairy industry. Therefore, timely and accurate detection of bovine mastitis is a crucial aspect of farm management. Existing portable detection devices: Some devices attempt to integrate single detection functions (such as SCC counting or pH detection only), but they have the following drawbacks: Sampling is inconvenient: It relies heavily on manual milking for sampling. Cows are prone to stress, making sampling difficult. In addition, the sampling process lacks temperature control, and samples are prone to bacterial growth at room temperature, affecting the accuracy of the test. Limited detection dimensions: Judging solely by a single indicator (such as color or odor) makes it difficult to comprehensively reflect the inflammatory state, resulting in a high false positive rate; Poor integration: The sampling and testing processes are separated, requiring manual sample transfer, which can easily lead to contamination; moreover, the device is large in size and complex to operate, making it unsuitable for ranch workers to quickly learn.

[0003] In addition, existing sampling devices often lack auxiliary functions, such as difficulty in milk discharge when the cow's udder contracts due to stress, resulting in low sampling efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a portable device for rapid detection of mastitis in dairy cows, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable device for rapid detection of mastitis in dairy cows, comprising a body and a storage box. A negative pressure tube is provided at one end of the body. A cover is fixedly supported at the top of the negative pressure tube by a stabilizing frame. Heating coils are evenly arranged on the side walls of the cover. An insulation sleeve is provided on the outside of the heating coils. Rotary motors are installed on both sides of the cover below the insulation sleeve. The output ends of the rotary motors extend to the inside of the cover and are connected to a rotating disk. Massage protrusions of different sizes are evenly arranged on the surface of the rotating disk. The output end of the cover is connected to the negative pressure tube through a liquid extraction tube. A servo motor is installed at the bottom of the negative pressure tube. The output end of the servo motor extends to the inside of the negative pressure tube and is connected to a threaded sleeve. A threaded rod is provided on the inner side of the top of the threaded sleeve. A piston is provided at the top of the threaded rod. The top of the machine body is equipped with a detection box. One end of the detection box is connected to a negative pressure pipe through an inlet pipe, and the inner side of the other end of the detection box is equipped with a movable tray. The top of the detection box is equipped with an odor sensor, a color detection sensor, and a vision sensor, whose detection ends extend to the movable tray.

[0006] Preferably, a handle is provided at one end of the bottom of the machine body, and a touch display is provided at the top of the machine body, and the touch display is connected to the PCB motherboard provided inside the handle.

[0007] Preferably, the battery compartment inside the body is equipped with a storage battery, and the opening of the battery compartment is provided with a sealing cover.

[0008] Preferably, a storage box is provided in the middle of the bottom of the machine body, and a test paper drawer and a waste drawer are respectively provided on both sides of the storage box.

[0009] Preferably, the liquid extraction pipe is equipped with a liquid extraction check valve, and the liquid inlet pipe is equipped with a liquid inlet check valve.

[0010] Preferably, the outer diameter of the piston matches the inner diameter of the negative pressure tube, and a sealing ring is provided on the outer side of the piston.

[0011] Preferably, the inside of the cover is provided with a silicone liner, and a Velcro fastener is provided between the bottom edge of the silicone liner and the top of the cover. The raw fibers of the Velcro fastener are fixedly connected to the silicone liner, and the barbs of the Velcro fastener are fixedly connected to the cover.

[0012] This invention provides a portable device for rapid detection of mastitis in dairy cows, which has significant advantages over existing technologies, specifically in the following aspects: 1. This device is equipped with an odor sensor, a color sensor, and a vision sensor on the top of the testing chamber, enabling comprehensive detection of milk samples from three dimensions: odor, color, and vision. Through the coordinated operation of multiple sensors, various abnormalities caused by inflammation in the milk can be more accurately identified, such as clots, flocculent matter, blood streaks, and turbidity. Compared to single-detection methods, this multi-dimensional detection approach significantly improves the accuracy and reliability of the test.

[0013] The design of the movable tray makes it more convenient to place and replace the test strips. The test strips qualitatively or semi-quantitatively detect esterases released by leukocytes through colorimetric reactions. Positive results directly indicate inflammation, further enhancing the accuracy of the test.

[0014] 2. The heating and massage functions inside the enclosure promote blood circulation in the cow's udder, making milk flow more easily and improving sampling efficiency. The design of the heating coil and insulation sleeve ensures temperature control during the sampling process, preventing sample deterioration due to unsuitable temperatures.

[0015] The piston system inside the negative pressure tube, driven by a servo motor, generates negative pressure downwards to facilitate rapid aspiration of milk samples; when the piston pushes upwards, it smoothly injects the sample into the testing chamber. This design not only simplifies the sampling process but also avoids contamination and loss of samples during transport.

[0016] 3. This device features a compact overall design, with a handle at the bottom and a touchscreen display at the top, making it easy to carry and operate. The connection between the touchscreen display and the PCB motherboard makes the user interface intuitive and user-friendly, allowing users to easily perform various testing operations.
