Description

Technical Field

[0001] The present invention relates to the technical field of sheep health monitoring and intelligent detection, and particularly relates to a sheep blood collection, blood routine and biochemical index intelligent detection system and method. Background Art

[0002] Sheep are important economic animals, and their health status is directly related to breeding efficiency and reproductive ability. Blood parameters, as important indicators for evaluating the health, physiological state and nutritional level of sheep, have been widely used in disease monitoring, growth performance evaluation and breeding management. Traditional blood tests generally rely on manual blood collection followed by submission for testing. The test indicators include blood routine (such as red blood cell count, white blood cell count, hemoglobin, etc.) and biochemical indicators (such as blood glucose, electrolytes, total protein, liver and kidney function indicators, etc.) to judge the body's immune function, metabolic state and potential diseases.

[0003] In the prior art, blood collection mostly relies on manual operation, which requires professional personnel, blood collection experience and strict operation procedures. There are problems such as low blood collection efficiency, high stress on sheep, and high risk of sample contamination. At the same time, blood samples need to be sent to the laboratory for testing using large-scale analytical instruments, with complex processes, long time, high cost, and it is not suitable for on-site real-time monitoring and the rapid detection needs of large-scale farms.

[0004] In recent years, although there have been some portable biochemical analyzers or point-of-care testing devices, most of them are designed for human use and have not been optimized for factors such as sheep blood collection sites, blood volume control, and physiological differences, and are not suitable for use in the livestock field. Moreover, most systems can only detect a single parameter or lack intelligent management functions, and cannot achieve the integration and automation of blood collection and multi-index detection, which limits their popularization and application in large-scale breeding and animal health intelligent monitoring.

[0005] Therefore, there is an urgent need to develop an intelligent system suitable for sheep that integrates blood collection, blood routine and biochemical index analysis, so as to improve blood collection efficiency, reduce stress response, improve detection accuracy, and achieve real-time data processing and remote management, providing technical support for sheep health monitoring and intelligent breeding.

Specific implementation manners

[0033] The following elaborates on this solution in combination with the accompanying drawings and specific implementation manners.

[0034] Figure 1 Schematic overall structure diagram of a sheep blood collection, blood routine and biochemical index intelligent detection system provided by an embodiment of the present application. Refer to Figure 1 , in a sheep blood collection, blood routine and biochemical index intelligent detection system in this embodiment, it includes: a central control processing unit and a sheep fixing module 1, an intelligent blood collection module 2, a sample identification and marking module 3, a blood detection module 4, and an automatic disinfection and blood collection needle replacement module that are electrically connected to the central control processing unit. After mechanically limiting and flexibly restraining the sheep to be pre-blood collected by the sheep fixing module 1, the central control processing unit is used to control the intelligent blood collection module 2 for individualized blood collection. After the blood collection is completed, the sample identification and marking module 3 is used for marking, and the blood detection module 4 is used for multi-index detection of the collected blood. Every time a blood collection is completed, the central control processing unit controls the automatic disinfection and blood collection needle replacement module to perform ultraviolet disinfection and replacement of the blood collection needle, automatically removes the blood collection needle used in the previous round through the waste needle ejection mechanism 39, and the new needle is replenished by the new needle spare warehouse 40 to ensure the efficient and continuous progress of subsequent blood collection, and at the same time ensure the pollution-free sampling of sheep.

[0035] To prevent sheep from moving excessively during blood collection and ensure that each sheep can be stably and comfortably fixed on the sheep fixing module 1 during blood collection, in this embodiment, a precise and gentle restraint is applied to the neck, limbs, and both sides of the abdomen of the sheep by combining a flexible pneumatic airbag and mechanical restriction. Refer to Figure 2 , which is a schematic structural diagram of the sheep fixing module provided in the embodiment of the present application. In this embodiment, the sheep fixing module 1 includes a fixed base 5. At the end of the fixed base 5, a first bracket 7 and a second bracket are fixedly arranged. On the first bracket 7 and the second bracket, a first clamping arm 6 and a second clamping arm are symmetrically arranged, and the clamping arms 6 are located on both sides of the abdomen of the sheep or at the junction of the chest and abdomen, and are adapted to the width of the sheep body to ensure that each sheep can be clamped. An electro-hydraulic pump and a plurality of clamping arm pressure sensors 8 are arranged on the first clamping arm 6 and the second clamping arm. In this embodiment, a clamping arm connecting member is arranged between the clamping arm 6 and the bracket 7. The first end of the clamping arm connecting member is movably connected to the bracket 7, and the second end of the clamping arm connecting member is fixedly connected to the clamping arm 6. The clamping arm 6 is regulated by the electro-hydraulic pump and the reversing valve to control the pressure direction, and the clamping arm 6 is controlled to clamp or loosen. The clamping force is monitored in real time through the clamping arm pressure sensor 8 to ensure the comfort of the animal.

[0036] In this embodiment, in order to adapt to sheep of different body types, a slider 10 is slidably arranged at the front end of the fixed base 5. A hydraulic lifting column 11 is arranged on the slider 10. A neck restraint assembly 15 is fixedly arranged on the hydraulic lifting column 11. An annular pneumatic airbag (not marked in the figure) is embedded in the inner wall arc groove of the neck restraint assembly 15. An air inlet port and a jugular vein blood collection opening 16 are arranged on the annular pneumatic airbag. Since the jugular vein blood collection opening 16 is on the annular pneumatic airbag body, the jugular vein blood collection opening 16 is automatically formed after the annular pneumatic airbag is inflated. During blood collection, the blood collection needle 21 can pass through the jugular vein blood collection opening 16 but will not damage the annular pneumatic airbag. The first end of the air inlet hose is connected to the annular pneumatic airbag through the air inlet port, and the second end of the air inlet hose is connected to the air pump 13. Pressure sensors 14 are arranged in the middle section of the air inlet hose and at the interface with the annular pneumatic airbag, and a pressure regulating valve 12 is arranged at the air pump interface. According to the morphological and body type differences of the sheep's neck, the system can automatically adjust the airbag inflation pressure to provide a suitable binding force, ensure the normal breathing and comfort of the sheep, and at the same time effectively prevent the sheep from shaking its neck due to discomfort or sudden movement during blood collection, ensuring the precise positioning of the blood vessel and the smooth progress of needle insertion.

[0037] In addition, a plurality of groups of parallel limit grooves 9 are arranged in parallel on the tabletop of the fixed base 5 of this embodiment. When the sheep enters the fixed base 5, its limbs are embedded in the limit grooves 9, and soft rubber pads are arranged in the limit grooves 9 to prevent the limbs of the sheep from being crushed.

[0038] Refer to Figure 3, the intelligent blood collection module 2 includes a bottom plate 25, on which a robotic arm 26 and a negative pressure collection unit 24 are fixedly arranged. A puncture mechanism 20 is movably arranged at the front end of the robotic arm 26. An infrared locator 18 and a visual recognition camera 19 are successively arranged at the top of the puncture mechanism 20. The detection ends of the infrared locator 18 and the visual recognition camera 19 face the ear margin or neck area of the sheep. In this embodiment, the infrared locator 18 is a key sensing component of the intelligent blood collection module 2, and its working principle is based on non-contact infrared thermal imaging technology. By detecting the subtle differences in the infrared radiation intensity on the skin surface, the temperature distribution in the blood circulation area is indirectly identified, and then the position of the subcutaneous blood vessels is judged. In the thermal image, the blood flow area appears as an obvious bright "tropical" trajectory, especially prominent in the superficial veins of the ear margin and neck, which is the main basis for the system to perform preliminary puncture positioning. In actual blood collection operations, the infrared locator 18 first performs a thermal image scan on the target site, and the obtained image is transmitted to the central control processing unit in real time via a cable. The system extracts continuous hot areas with temperatures higher than the background through algorithms such as thermal intensity gradient detection, temperature threshold segmentation, and morphological filtering to complete preliminary blood vessel positioning. To further improve the recognition accuracy, the system fuses the structural continuity and morphological features of the blood vessels to eliminate artifacts caused by muscle tremors or skin reflections. Based on the infrared thermal image recognition in this embodiment, the system activates the visual recognition camera 19 to obtain high-resolution visible light images, and through algorithms such as image enhancement, edge detection, blood vessel enhancement filtering, and image segmentation, realizes the accurate extraction of the blood vessel boundary, width, and center line. The two image information is fused and superimposed in the central control processing unit to improve the accuracy of blood vessel positioning and the accuracy of puncture point determination. The visual module of the system is equipped with a dynamic tracking function, which can capture the slight displacement or breathing disturbance of the sheep at any time, and correct the puncture coordinates in real time through algorithms to ensure the accurate alignment of the subsequent puncture path.

[0039] In this embodiment, a blood collection needle 21 is provided at the port of the puncture mechanism 20. A vacuum-grade flexible silicone tube 27 is connected to the outlet of the blood collection needle 21. The negative pressure collection unit 24 is used to transmit the blood extracted by the blood collection needle 21 to the blood collection tube 22 through the vacuum-grade flexible silicone tube 27. The system regulates the suction rate through a feedback algorithm to ensure a smooth and gentle blood collection process, effectively reducing the negative pressure stimulation on tissues during blood collection and reducing the stress response of sheep. A real-time monitoring module and a stepper motor are embedded in the puncture mechanism 20. The real-time monitoring system is electrically connected to the stepper motor. The blood collection needle 21 is arranged on the rotating output shaft of the stepper motor. The system automatically adjusts the speed and propulsion distance of the stepper motor according to individual parameters (such as skin thickness, blood vessel depth, etc.), making the needle insertion process more gentle and accurate, and effectively reducing the trauma to tissues. At the same time, the real-time monitoring module detects the motor load change, current fluctuation and the force feedback signal at the front end of the blood collection needle 21. Once an abnormality is detected (such as an increase in needle resistance or failure to enter the blood vessel), the system immediately triggers a feedback mechanism to adjust the puncture strategy or issue a warning to ensure the puncture safety and success rate.

[0040] In this embodiment, a highly cooperative working mechanism is established between the stepper motor and the negative pressure collection unit 24, and both are uniformly managed by the central control processing unit. After the stepper motor accurately advances the blood collection needle 21 into the blood vessel, the negative pressure collection unit 24 starts the suction operation and dynamically adjusts the extraction speed and negative pressure value according to the blood collection process. This cooperation mechanism not only improves the efficiency and accuracy of puncture blood collection, but also effectively reduces the system error and the risk of animal stress, and significantly enhances the self-adaptability and practicability of the intelligent blood collection device.

[0041] See Figure 4 , in this embodiment, the sample identification and marking module 3 includes a radio frequency identification tag printer 28. The tag outlet end of the radio frequency identification tag printer 28 corresponds to the blood collection tube placed in the blood collection tube tray 29. An induction area is set at the preset height position of the blood collection tube tray 29. The robotic arm transmission module 30 is arranged between the blood collection tube tray 29 and the blood detection module 4. The radio frequency identification tag sprays and prints to bind the sheep identification code through the tag head, automatically reads and confirms the sample position through the induction area, and the robotic arm transmission module 30 transfers the collected sample to the entrance of the blood detection module 4.

[0042] See Figure 5, in this embodiment, a micro mixer and a plasma separation membrane 34 are sequentially arranged at the inlet of the blood detection module 4. After the blood passes through the micro mixer and the plasma separation membrane 34, automatic separation of whole blood and serum can be achieved. A blood routine detection unit 32 and a biochemical detection unit 33 are arranged in the blood detection module 4. The blood routine detection unit 32 adopts an impedance method micro detection chip and supports the detection of indicators such as red blood cells (RBC), hemoglobin (HGB), white blood cells (WBC), and platelets (PLT). The biochemical detection unit 33 uses dry reagent strips and a photoelectric colorimetric module to detect biochemical parameters such as glucose (GLU), total protein (TP), albumin (ALB), calcium ion (Ca 2 +), ALT, and AST.

[0043] In this embodiment, the central control processing unit includes an embedded processor 35, a data processing module 36, and a human-computer interaction touch screen 37. The processor performs logical control, status monitoring, and abnormal detection on the system operation. The data processing module 36 pre-analyzes the detection data. The human-computer interaction touch screen 37 provides interface operations, result display, and sheep information input.

[0044] In addition, in this embodiment, the sheep blood collection and blood routine and biochemical index intelligent detection system further includes a wireless communication module. The wireless communication module includes Wi-Fi, a 5G communication module, and a data upload interface, and can transmit the detection data to the cloud database, the breeding management system, or the mobile terminal in real time, facilitating remote viewing and record management by users.
