Description

Technical Field

[0001] The present invention relates to the technical field of bovine whole blood collection, and more specifically to a bovine whole blood collection device. Background Art

[0002] The collection of whole blood from cattle is of great significance in the fields of animal husbandry, veterinary research, and biomedicine. In animal husbandry, the detection of whole blood from cattle can help assess the health of cattle, such as detecting various biochemical indicators and pathogen antibodies in the blood, so as to detect diseases in a timely manner, conduct disease prevention and control, and genetic breeding research. In veterinary clinics, the collection of whole blood from cattle is one of the important means of diagnosing diseases. By analyzing the blood components, the body functions and disease conditions of cattle can be accurately judged, providing a basis for formulating reasonable treatment plans. In biomedical research, certain components in cattle blood, such as coagulation factors and serum proteins, are also widely used and can be used for drug development, production of biological products, etc. Collection equipment is required when collecting whole blood from cattle.

[0003] However, the existing whole blood collection equipment for cattle has many shortcomings in the whole blood collection of cattle. It often lacks a special device for synchronous delivery and precise mixing of blood and anticoagulants. It mostly relies on manual operation to add anticoagulants, which makes it difficult to ensure that the anticoagulant and blood are mixed in a predetermined ratio and flow rate, affecting the collection efficiency and quality. In addition, due to the lack of mixing components, the blood and anticoagulant are mixed unevenly, which greatly increases the risk of blood coagulation and easily causes sample loss. Subsequent experiments have a high risk of error due to large sample differences. In view of this, we propose a whole blood collection equipment for cattle. Summary of the invention

[0038] Working method: The blood drip pot 2 is connected to the blood collection device of the cow, and the peristaltic pump 4 transports the blood through the blood drip pot 2 to one end of the mixing component 6, which is connected to the external anticoagulant delivery device through the anticoagulant tube 3. Another peristaltic pump 4 transports the anticoagulant through the anticoagulant tube 3 to the other end of the mixing component 6. The blood and the anticoagulant are mixed during the transportation process, making the blood less likely to coagulate, and then discharged through the discharge pipe 7. During the transportation process, the blood collection situation is detected by the pipeline pressure sensor 5.

[0039] The present invention is that when the blood drip pot 2 is connected to the blood collection device of the cattle, the peristaltic pump 4 connected thereto delivers the collected cattle blood to one end of the mixing component 6 through the blood drip pot 2, and at the same time, the anticoagulant tube 3 is connected to the external anticoagulant delivery device, and another peristaltic pump 4 delivers the anticoagulant to the other end of the mixing component 6 through the anticoagulant tube 3 according to a predetermined ratio and flow rate. Inside the mixing component 6, the blood and the anticoagulant are fully intersected and fused under the promotion of the peristaltic pump 4, and the two can be quickly and evenly mixed together by virtue of the mixing structure and flow channel, thereby effectively inhibiting the coagulation tendency of the blood, and ensuring that the collected cattle whole blood always maintains good fluidity and activity during subsequent processing and storage. The present invention not only improves the efficiency and quality of cattle whole blood collection, but also reduces the risk of sample loss and experimental error caused by blood coagulation.

[0040] Specifically, Figures 5 to 8As shown, the mixing assembly 6 involved in the present invention includes a mixing sleeve 601, a mixing sleeve head 602, a mixing drive structure 603, a sleeve exit structure 604, and a flow equalizing tube 605; the main pipe of the flow equalizing tube 605 is connected to the output end of the peristaltic pump 4 connected to the anticoagulant tube 3, and the five branch pipes of the flow equalizing tube 605 are all connected to the mixing sleeve 601, the sleeve exit structure 604 is installed in the shell 1, and the output end of the sleeve exit structure 604 is installed on the mixing sleeve 601, the mixing drive structure 603 is slidably connected in the shell 1, and the output end of the mixing drive structure 603 is located in the mixing sleeve 601, the mixing sleeve head 602 is installed on the mixing drive structure 603, the mixing sleeve head 602 is sleeved on the mixing sleeve 601, and the mixing sleeve head 602 and the internal space of the mixing sleeve 601 form a mixing channel, the mixing sleeve 601 is connected to the output end of the peristaltic pump 4 connected to the blood dropper, and the discharge pipe 7 is connected to the mixing sleeve 601.

[0041] The hybrid drive structure 603 includes a first frame 6031, a first drive motor 6032, and a mixing rod 6033; the mixing rod 6033 is located in the mixing sleeve 601, and the mixing rod 6033 is installed at the output end of the first drive motor 6032, the first drive motor 6032 is installed in the first frame 6031, and the output end of the first drive motor 6032 passes through the outside of the first frame 6031, and the first frame 6031 is slidably connected in the outer shell 1.

[0042] Working method: blood is introduced through the mixing sleeve 601, and the anticoagulant is evenly introduced into various positions of the mixing sleeve 601 through the flow equalizing tube 605. The mixing rod 6033 is driven to rotate by the first driving motor 6032. The mixing rod 6033 rotates in the mixing sleeve 601, and the anticoagulant and blood are mixed and then discharged through the discharge tube 7.

[0043] It is worth noting that if Figures 7 and 8 As shown, the mixing drive structure 603 involved in the present invention also includes mixing blades 6034 and mixing straight rods 6035; the mixing blades 6034 are semi-helical curved surface structures, three mixing blades 6034 form a mixing blade 6034 group, and the three mixing blades 6034 in each group are arranged in an annular shape equidistantly along the radial direction of the mixing rod 6033, and ten mixing blade 6034 groups are arranged equidistantly along the axial direction of the mixing rod 6033; the mixing straight rod 6035 is a cylindrical structure, three mixing straight rods 6035 form a mixing straight rod 6035 group, and the three mixing straight rods 6035 in each group are arranged in an annular shape equidistantly along the radial direction of the mixing rod 6033, and twenty mixing straight rods 6035 groups are arranged equidistantly along the axial direction of the mixing rod 6033, and the mixing rod 6033 is located between two adjacent mixing blades 6034.

[0044] Working method: When the mixing rod 6033 rotates, the mixing blades 6034, with their semi-helical curved surface structure, are arranged in an annular shape equidistantly along the radial direction of the mixing rod 6033 in each group of three mixing blades 6034, and the ten mixing blades 6034 groups are equidistantly distributed along the axial direction. Therefore, when the mixing rod 6033 rotates, the blood and anticoagulant are pushed, flipped and guided in an orderly manner by the blades. At the same time, a mixing straight rod 6035 group consisting of three mixing straight rods 6035 is arranged in an annular shape equidistantly along the radial direction of the mixing rod 6033, and twenty mixing straight rods 6035 groups are equidistantly distributed along the axial direction. The mixing rod 6033 is located between two adjacent mixing blades 6034. The cylindrical structure and specific layout of the mixing straight rods 6035 also serve to assist in stirring and dispersing.

[0045] The present invention, by virtue of its mixing blade 6034 with a semi-helical curved surface structure, produces a unique diversion and stirring effect on blood and anticoagulant during the rotation process, and can be fully mixed at different radial and axial positions. Through the cylindrical mixing straight rod 6035, the mixing straight rod 6035 can break the local mixing dead angle that may be formed during rotation, further enhancing the mixing uniformity and stability of blood and anticoagulant, allowing the two to achieve efficient and accurate mixing in a relatively short time. The present invention can ensure that the whole blood of cattle is fully mixed after collection, quickly enters the ideal anticoagulation state, and effectively guarantees the quality and efficiency of the whole blood collection work of cattle.

[0046] Further, such as Figures 5 to 8 As shown, the hybrid drive structure 603 involved in the present invention also includes a slider 6036, a slide groove 6037, and a limit rod 6038; the limit rod 6038 is installed outside the first frame 6031, and the other end of the limit rod 6038 is abutted against a maintenance plate 103, the maintenance plate 103 is detachably connected to the rear of the shell 1, the slide groove 6037 is arranged inside the shell 1, the slider 6036 is slidably connected in the slide groove 6037, and the slider 6036 is installed outside the first frame 6031.

[0047] The sleeve withdrawal structure 604 includes a screw sleeve 6041, a screw rod 6042, a second drive motor 6043, and a second frame 6044; the second frame 6044 is installed in the outer shell 1, the second drive motor 6043 is installed in the second frame 6044, and the output end of the second drive motor 6043 passes through the outside of the second frame 6044, the screw rod 6042 is installed at the output end of the second drive motor 6043, the screw sleeve 6041 is threadedly connected to the screw rod 6042, and the screw sleeve 6041 is installed on the mixing sleeve 601.

[0048] The sleeve withdrawal structure 604 further includes a guide rod 6045 , which is mounted on the second frame 6044 , and the other end of the guide rod 6045 is slidably connected to the threaded sleeve 6041 .

[0049] Working method: When the equipment needs to be repaired or maintained, during the operation of withdrawing the mixing sleeve 601, the second drive motor 6043 is started, and its output end drives the screw 6042 to rotate. Due to the threaded connection between the screw sleeve 6041 and the screw 6042, the screw sleeve 6041 will move linearly along the axial direction of the screw 6042, and the screw sleeve 6041 is installed on the mixing sleeve 601, thereby driving the mixing sleeve 601 to withdraw. In this process, the guide rod 6045 plays a guiding and stabilizing role. One end is installed on the second frame 6044, and the other end is slidably connected to the screw sleeve 6041, ensuring that the movement direction of the screw sleeve 6041 driven by the screw rod 6042 is accurate and stable. After the mixing sleeve 601 is withdrawn, it no longer forms an obstacle to the mixing rod 6033. Then the maintenance plate 103 is removed from the rear of the shell 1. At this time, the limit rod 6038 loses its abutment constraint, and the position of the first frame 6031 can be adjusted by sliding the slider 6036 in the slide groove 6037, thereby driving the mixing rod 6033 to move, and then the mixing rod 6033 can be cleaned.

[0050] The present invention cooperates with the screw sleeve 6041, the screw rod 6042, the second drive motor 6043 and the guide rod 6045 in the sleeve withdrawal structure 604 to smoothly withdraw the mixing sleeve 601, freeing up a safe and barrier-free operating space for subsequent maintenance operations, and the combination of the slider 6036, the slide groove 6037 and the limit rod 6038 in the mixing drive structure 603 can flexibly shift the mixing rod 6033, greatly facilitating the cleaning of the mixing rod 6033 and ensuring that it is always in good working condition. The present invention can effectively prevent equipment failure or performance degradation caused by inadequate cleaning of components, thereby significantly extending the service life of the equipment, improving the reliability and stability of the operation of the bovine whole blood collection equipment, and reducing equipment maintenance costs and downtime.
