Description

Technical Field

[0001] The present invention relates to the technical field of animal quarantine and medical equipment, and in particular to a blood sampling device for animal quarantine. Background Art

[0002] Thanks to the continuous advancement of animal quarantine technology, blood sampling devices play an important role in disease detection, experimental research, and clinical diagnosis. However, existing animal quarantine blood sampling devices still have certain limitations in terms of ease of use, scope of application, and blood collection efficiency, which affect their practical application.

[0003] After searching, a blood sample collection device for animal disease detection with publication number CN115778614B was found, with a publication date of May 2, 2023. This patent realizes the rapid restraint and blood collection operations on the neck of animals of different heights by setting a resistance mechanism, a locking mechanism and an adjustment mechanism, effectively reducing the situation where animals struggle violently due to pain. However, this technical solution is more suitable for small and medium-sized animals, and its adaptability to the blood collection needs of large animals is relatively limited. In addition, the structure of the device is relatively complex, and there are many operating steps, which may reduce the efficiency of blood collection and is not convenient enough when used in the wild or in emergency scenarios.

[0004] After searching, a blood sample collection device for animal disease detection with publication number CN119454024B was found, and the publication date was March 18, 2025. This patent realizes cross-infection-free operation during the blood collection process through the design of the cover, needle box, turntable and lever, and uses the turntable to replace the blood collection tube, which improves the accuracy and continuity of blood collection. However, the device is large in size and has average portability, and it is challenging to adapt to the blood collection needs in the field or mobile scenarios. At the same time, the device has high technical requirements for operators, which may increase training costs and operation difficulty, especially when dealing with multiple types of animals, the flexibility is subject to certain restrictions.

[0005] The above issues indicate that existing animal quarantine blood collection devices still have room for improvement in terms of portability, versatility, and ease of use. Therefore, the present invention provides a novel animal quarantine blood collection device designed to optimize its structure, enhance its portability and applicability, simplify the operating process, and improve blood collection efficiency, thereby better meeting the demand for efficient and flexible blood collection devices in the animal quarantine field. Summary of the Invention

[0006] This invention provides a blood sampling device for animal quarantine. By optimizing its structural design and operational procedures, it addresses existing issues such as limited portability, poor versatility, and complex operation. The device comprises a main frame, a blood sampling assembly, an adjustment mechanism, and an auxiliary positioning module. These components are connected together to form a unified whole, enabling efficient blood sampling in various scenarios.

[0007] The main frame is constructed from lightweight, high-strength materials and features a foldable design for easy portability and storage. Fixed and movable interfaces are located at each end of the frame, respectively, for mounting the blood collection assembly and adjustment mechanism. The fixed interface connects to the blood collection assembly via a threaded connection, while the movable interface utilizes a slide rail structure to engage the adjustment mechanism, allowing the blood collection position to be adjusted to the animal's size. A central cavity is located within the main frame for storing blood collection tubes and other auxiliary tools, further enhancing the device's portability.

[0008] The blood collection assembly consists of a needle unit, a blood collection tube holder, and an anti-backflow module. The needle unit is connected to the blood collection tube holder by a rotating buckle, ensuring that the needle can be quickly replaced during the blood collection process to avoid cross-infection. The blood collection tube holder is equipped with an elastic clip that can adapt to blood collection tubes of different specifications, while maintaining the stability of the blood collection tube through spring force. The anti-backflow module is located at the rear end of the needle unit and consists of a one-way valve and a filter membrane to prevent blood from flowing back and contaminating the internal structure of the device. The blood collection assembly is connected to the main frame through a fixed interface, and the angle is adjusted by a locking knob to adapt to the anatomical structure of different animals.

[0009] The adjustment mechanism consists of a telescopic rod, an angle adjustment disk, and a locking device, which are used to adjust the spatial position and angle of the blood collection component. The telescopic rod adopts a multi-section nested design, and each section is fixed by a limit pin, and the length can be freely adjusted as needed. The angle adjustment disk is set at the end of the telescopic rod, and the angle of the blood collection component is changed by gear engagement. The locking device adopts a ratchet structure, and the locking state is controlled by a manual lever to ensure that the adjusted blood collection component remains stable. The adjustment mechanism is connected to the main frame through a movable interface. The movable interface has a built-in ball bearing, making the adjustment process smoother and more precise.

[0010] The auxiliary positioning module includes a flexible restraint, a pressure sensor, and an indicator light group, which are used to improve the accuracy and safety of the blood collection process. The flexible restraint is wrapped around the animal's limbs or neck, fixed with Velcro, and has built-in elastic steel wire to enhance support. Pressure sensors are evenly distributed on the inside of the flexible restraint, monitoring the restraint force in real time and displaying it through the indicator light group. The indicator light group contains three colors: red, yellow, and green, corresponding to excessive, appropriate, and too low restraint forces respectively. The operator can adjust the tightness of the restraint according to the indicator light prompts to avoid animal injuries or blood collection failures due to improper restraint. The auxiliary positioning module is connected to the main frame with a buckle, and installation and removal are simple and quick.

[0011] Through the above-mentioned structural design, the present invention significantly improves the portability, versatility and ease of operation of the blood sampling device for animal quarantine. The folding design of the main frame and the setting of the accommodating cavity make the device easier to carry and use in the field or in emergency scenarios. The modular design of the blood sampling component and the application of the anti-backflow module effectively reduce the risk of cross-infection and improve the blood collection efficiency. The multi-degree-of-freedom adjustment capability of the adjustment mechanism enables the device to adapt to animals of different sizes and types, expanding the scope of application. The pressure sensor and indicator light group of the auxiliary positioning module provide intuitive feedback information to the operator, reducing the difficulty of operation and the technical threshold.

[0012] In addition, the present invention also provides a blood collection method for animal quarantine, which uses the above-mentioned device to complete the blood collection task. First, the main frame is unfolded and fixed in a suitable position, and the length and angle of the adjustment mechanism are adjusted according to the animal's body shape so that the blood collection component is aligned with the target blood vessel. Subsequently, the flexible restraint is fixed to the animal's limbs or neck, and the restraint force is adjusted to an appropriate range by observing the indicator light group. Next, the blood collection tube is inserted into the blood collection tube holder and the locking state is confirmed to start the blood collection operation. After the blood collection is completed, the needle unit is quickly replaced by rotating the buckle to prepare for the next blood collection.

[0013] The technical solution of the present invention solves the problems mentioned in the background art, such as insufficient portability, poor versatility, and complex operation, by optimizing the structure and integrating the functions of existing blood collection devices. The lightweight design and folding function of the main frame directly address the defects of the existing devices, such as large size and poor portability; the modular design of the blood collection components and the application of the anti-backflow module overcome the problems of high risk of cross-infection and low blood collection efficiency; the multi-degree-of-freedom adjustment capability of the adjustment mechanism and the intelligent design of the auxiliary positioning module make up for the shortcomings of the existing devices, such as insufficient flexibility and high difficulty of operation.

[0014] In summary, the present invention achieves comprehensive optimization of the blood collection device for animal quarantine through specific structural design and technical means, which not only meets the needs of efficient and flexible blood collection, but also provides more reliable technical support for the field of animal quarantine.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] The present invention provides a blood sampling device for animal quarantine, the structure of which is as follows: Figures 1 to 5 The device comprises a main frame 1, a blood collection component 2, an adjustment mechanism 3 and an auxiliary positioning module 4. Each component is connected in a specific manner to form a whole, which can complete the blood collection task in different scenarios. The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] The main frame 1 is made of lightweight and high-strength materials and is designed to be foldable. Figure 5 As shown. The two ends of the main frame 1 are respectively provided with a fixed interface 5 and a movable interface 6. The fixed interface 5 is located at one end of the main frame 1 and is connected to the blood collection component 2 by a threaded connection. The movable interface 6 is located at the other end of the main frame 1, and is embedded with a ball bearing inside, and cooperates with the adjustment mechanism 3 through a slide rail structure. A accommodating chamber 16 is provided in the middle of the main frame 1 for storing blood collection tubes and other auxiliary tools. The position of the accommodating chamber 16 is shown as follows. Figure 5 When in use, the main frame 1 can be kept in a stable state by the locking device after being unfolded, so that the operator can conveniently perform blood collection operation.

[0026] The blood collection assembly 2 is composed of a needle unit 7, a blood collection tube holder 8 and a backflow prevention module 9. Figure 2As shown. The needle unit 7 is connected to the blood collection tube holder 8 by a rotary buckle. The design of the rotary buckle enables the needle unit 7 to be quickly replaced. An elastic clip is provided inside the blood collection tube holder 8. The elastic clip fixes the blood collection tube in the holder through the action of spring force, ensuring that the blood collection tube remains stable during the blood collection process. The anti-backflow module 9 is located at the rear end of the needle unit 7 and is composed of a one-way valve and a filter membrane. The one-way valve and the filter membrane are fixed inside the anti-backflow module 9 through an injection molding process. The blood collection component 2 is connected to the main frame 1 through a fixed interface 5, and the angle is adjusted by a locking knob. The locking knob is located on the outside of the fixed interface 5 and the angle of the blood collection component 2 can be adjusted by manual rotation.

[0027] The adjustment mechanism 3 is composed of a telescopic rod 10, an angle adjustment disk 11 and a locking device 12. Figure 3 As shown. The telescopic rod 10 adopts a multi-section nested design, and each section is fixed by a limit pin. The limit pin is located on the outside of the telescopic rod 10, and the length can be adjusted by manual adjustment. The angle adjustment disk 11 is set at the end of the telescopic rod 10, and the angle change of the blood collection component 2 is achieved by gear meshing. The gear meshing part is located inside the angle adjustment disk 11. The locking device 12 adopts a ratchet structure. The ratchet structure controls the locking state through a manual lever. The manual lever is located on the outside of the locking device 12. The adjustment mechanism 3 is connected to the main frame 1 through a movable interface 6. A ball bearing is embedded in the movable interface 6. The ball bearing is fixed in the movable interface 6 by a press-fitting process, making the adjustment process smoother and more precise.

[0028] The auxiliary positioning module 4 includes a flexible restraint belt 13, a pressure sensor 14 and an indicator light group 15, and its layout is as follows: Figure 4 As shown. The flexible restraint 13 is wrapped around the animal's limbs or neck and fixed by Velcro, and the fur surface and hook surface of the Velcro are respectively located at the two ends of the flexible restraint 13. The flexible restraint 13 has a built-in elastic steel wire, and the elastic steel wire is fixed inside the flexible restraint 13 through a weaving process to enhance the supporting force. The pressure sensors 14 are evenly distributed on the inside of the flexible restraint 13. The pressure sensors 14 are connected to the indicator light group 15 through a wire, and the wire is arranged along the inside of the flexible restraint 13. The indicator light group 15 includes LED lights in three colors: red, yellow and green. The LED lights are fixed inside the indicator light group 15 through a circuit board, and the circuit board is connected to the pressure sensor 14 through a welding process. The auxiliary positioning module 4 is connected to the main frame 1 through a buckle. The buckle is located at one end of the flexible restraint 13 and can be installed and removed by manually pressing.

[0029] During actual use, the main frame 1 is first unfolded and fixed in a suitable position. The unfolded main frame 1 is kept stable by a locking device. The length and angle of the adjustment mechanism 3 are adjusted according to the body shape of the animal. The length of the telescopic rod 10 is adjusted by the limit pin, the angle of the angle adjustment disk 11 is adjusted by gear engagement, and the manual lever of the locking device 12 controls the locking state. The flexible restraint 13 is then fixed to the animal's limbs or neck, and the restraint force is adjusted to an appropriate range by observing the indicator light group 15. The blood collection tube is then inserted into the blood collection tube holder 8 and the locking state is confirmed to start the blood collection operation. During the blood collection process, the needle unit 7 is connected to the blood collection tube holder 8 by rotating the buckle, and the anti-backflow module 9 prevents blood from flowing back and contaminating the internal structure of the device. After the blood collection is completed, the needle unit 7 is quickly replaced by rotating the buckle to prepare for the next blood collection.

[0030] The foldable design of the main frame 1 makes it easier to carry and use in the wild or in emergency situations. The storage chamber 16 is used to store blood collection tubes and other auxiliary tools. The modular design of the blood collection assembly 2 allows for quick replacement of the needle unit 7. The anti-backflow module 9 prevents blood from flowing back through a one-way valve and filter membrane. The multi-degree-of-freedom adjustment capability of the adjustment mechanism 3 enables the device to adapt to animals of different sizes and species. The pressure sensor 14 and indicator light group 15 of the auxiliary positioning module 4 provide intuitive feedback to the operator, reducing the difficulty and technical barriers to operation.

[0031] The present invention achieves comprehensive optimization of the blood sampling device for animal quarantine through the above-mentioned structural design, meets the needs of efficient and flexible blood sampling, and provides reliable technical support for the field of animal quarantine.

[0032] In order to better enable relevant personnel in this technical field to fully understand and implement the present invention, the specific implementation principle of the present invention is further supplemented below with reference to a specific application scenario.

[0033] When collecting blood for animal quarantine in the wild, the operator first unfolds the main frame 1 from its folded state and secures it in a stable position using a locking device. The lightweight, high-strength material and foldable design of the main frame 1 significantly reduce the carrying burden, while the design of the accommodating chamber 16 ensures that blood collection tubes and other auxiliary tools can be neatly stored, avoiding operational delays caused by scattered tools. Subsequently, the operator adjusts the length of the telescopic rod 10 of the adjustment mechanism 3 according to the size of the target animal, and achieves precise length locking by manually turning the limit pin. During this process, the multi-section nested design of the telescopic rod 10 provides a large adjustment range, ensuring that the device can adapt to animals of different sizes.

[0034] Next, the angle adjustment disk 11 adjusts the angle of the blood collection assembly 2 through gear meshing, allowing the needle unit 7 to accurately align with the target blood vessel. The gear meshing design ensures precise angle adjustment, while the ratchet mechanism of the locking mechanism 12, controlled by a manual lever, prevents angle deviation caused by external interference. At this point, the operator can adjust the tightness of the flexible restraint 13 by observing the indicator light group 15 in the auxiliary positioning module 4. The pressure sensor 14 monitors the restraint force in real time and transmits a signal to the indicator light group 15 via a circuit board, causing it to display the corresponding color. For example, when the indicator light group 15 displays red, it indicates that the restraint force is too high and the operator needs to loosen the flexible restraint 13 appropriately; when it displays green, it indicates that the restraint force is within the appropriate range. This intuitive feedback mechanism effectively reduces operational difficulty, making it particularly suitable for novice operators or for quick operation in emergency situations.

[0035] After the binding is completed, the operator inserts the blood collection tube into the blood collection tube holder 8 and ensures that the blood collection tube is firmly fixed by the spring force of the elastic clip. The one-way valve and filter membrane in the anti-backflow module 9 play a key role in this process. Its injection molding process ensures the sealing and stability of the internal structure of the module, thereby preventing blood from flowing back and contaminating the interior of the device. Subsequently, the operator starts the blood collection operation, and the needle unit 7 is connected to the blood collection tube holder 8 by rotating the buckle, ensuring the continuity and efficiency of the blood collection process. After the blood collection is completed, the operator quickly replaces the needle unit 7 by rotating the buckle to prepare for the next blood collection.

[0036] In the above steps, the foldable design of the main frame 1 and the setting of the accommodating chamber 16 realize the high portability of the device, especially in the field or emergency scenarios, the operator can quickly unfold the device and put it into use. The modular design of the blood collection component 2 significantly reduces the risk of cross infection by quickly replacing the needle unit 7, while improving the blood collection efficiency. The multi-degree-of-freedom adjustment capability of the adjustment mechanism 3, through the synergistic effect of the telescopic rod 10 and the angle adjustment disk 11, enables the device to flexibly adapt to animals of different sizes and types, expanding the scope of application. The pressure sensor 14 and indicator light group 15 of the auxiliary positioning module 4 reduce the technical threshold of the operator through real-time monitoring and intuitive feedback, thereby improving the safety and accuracy of blood collection.

[0037] In summary, the present invention, through the operating principles and steps in the above-mentioned specific application scenarios, demonstrates how to utilize the synergistic effect of the main frame 1, the blood collection component 2, the adjustment mechanism 3 and the auxiliary positioning module 4 to solve the problems of insufficient portability, poor versatility and complex operation in the existing technology, thereby meeting the demand for efficient and flexible blood collection devices in the field of animal quarantine.
