Technical Field
[0001] This invention relates to the field of blood collection technology, specifically to an integrated device for blood collection and testing cards. Background Technology
[0002] Currently, animal blood testing is widely used in pet medical care, biological testing and other fields. Existing testing methods mostly adopt decentralized operation, which requires independent instruments such as blood collection needles, centrifuge tubes and test cards. The process is cumbersome and difficult to operate. At the same time, the use of multiple instruments can easily cause sample contamination and cross-infection. The testing time is long and the results are not stable enough, which makes it difficult to meet the needs of rapid on-site screening and immediate diagnosis, and is not conducive to popularization and application in grassroots and home settings.
[0003] In traditional testing, blood needs to be manually transferred to a processing container after collection, which can easily cause blood contamination and serum loss, affecting the accuracy of the test. In addition, the many steps involved result in low testing efficiency and cannot meet the needs of rapid on-site testing. Furthermore, most existing devices are not integrated into a single unit, and their operation relies on professional personnel, resulting in poor adaptability and making it difficult to meet the actual needs of grassroots testing and on-site screening scenarios. Summary of the Invention
[0004] The purpose of this invention is to provide an integrated blood collection and testing card device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated blood collection and testing card device, comprising a blood collection needle and a testing card body, wherein a flexible tube is installed at one end of the blood collection needle, and a vacuum storage tube is provided at one end of the flexible tube, a serum processing tube is provided at the bottom of the vacuum storage tube, and a connecting component for rapid blood guidance is installed between the vacuum storage tube and the serum processing tube, and the connecting component includes an inner slot and an outer slot plate, wherein the outer slot plate is slidably installed inside the inner slot, and the testing card body is located at the bottom of the serum processing tube.
[0006] Furthermore, the main body of the detection card is provided with an auxiliary component for assisting in blood detection, and the auxiliary component includes a card slot and a needle, with the needle disposed inside the card slot.
[0007] Furthermore, an observation window is installed inside the main body of the detection card on the side near the auxiliary components, and two sets of observation windows are provided.
[0008] Furthermore, a cap is installed on the top of the vacuum storage tube, and an inner plug is provided inside the cap.
[0009] Furthermore, the vacuum storage vessel has an internal groove, and the central axis of the internal groove does not coincide with the central axis of the vacuum storage vessel.
[0010] Furthermore, a sealing gasket is provided at the bottom of the built-in groove, and the sealing gasket is integrated with the serum processing tube, and the diameter of the sealing gasket is smaller than the diameter of the serum processing tube.
[0011] Furthermore, the serum processing tube is equipped with a blood filtration membrane pad inside, and aluminum foil is installed at the bottom of the serum processing tube, with two sets of aluminum foil.
[0012] This invention provides an integrated blood collection and testing card device, which has the following beneficial effects: 1. This invention features an integrated design for blood collection, serum processing, and testing, significantly simplifying the operation process. It eliminates the need for separate instruments such as blood collection needles, centrifuge tubes, and test cards, and also eliminates the need for manual transfer of blood or serum. This effectively reduces the operational difficulty and workload for operators, while avoiding problems such as blood contamination and serum loss during transfer, thus improving testing efficiency. The device achieves automatic negative pressure blood collection through the cooperation of blood collection needles, tubing, and vacuum storage tubes. The rotating locking design of the connecting components ensures precise flow path conduction and sealing. The auxiliary components' needles and aluminum foil work together to achieve rapid serum introduction. The synergistic effect of all components allows the entire testing process to be completed quickly, adapting to the needs of rapid on-site testing.
[0013] 2. This invention prevents blood clotting by using an anticoagulant in the built-in groove of the vacuum storage tube, and effectively filters red blood cells by using a blood filtration membrane pad treated with anti-red blood cell antibodies in the serum processing tube to obtain pure serum, avoiding interference from red blood cells in the test results. In the initial state, the tight fit between the sealing pad and the built-in groove, and the sealing design of the aluminum foil, prevent blood or serum leakage and reduce the risk of cross-contamination. The snap-fit positioning design of the connecting components ensures the stability of the flow path and the seal, avoiding blood leakage or flow path blockage caused by improper operation.

[0015] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.
[0016] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the integrated blood collection and testing device includes a blood collection needle 1, a flexible tube 2, a tube cap 3, an inner plug 4, a vacuum storage tube 5, a serum processing tube 6, a testing card body 7, a connecting assembly 8, an inner card slot 801, an outer card plate 802, auxiliary components 9, a card slot 901, a needle 902, an aluminum foil 10, an internal groove 11, a sealing gasket 12, a blood filtration membrane gasket 13, and an observation window 14. A flexible tube 2 is installed at one end of the blood collection needle 1, and a vacuum storage tube 5 is installed at the other end of the flexible tube 2. An internal groove 11 is formed inside the vacuum storage tube 5, and the central axis of the internal groove 11 does not coincide with the central axis of the vacuum storage tube 5. A sealing gasket 12 is installed at the bottom of the internal groove 11, and the groove is sealed. The sealing gasket 12 and the serum processing tube 6 are integrated, and the diameter of the sealing gasket 12 is smaller than the diameter of the serum processing tube 6. The serum processing tube 6 is located at the bottom of the vacuum storage tube 5. A blood filtration membrane gasket 13 is installed inside the serum processing tube 6. Two sets of aluminum foil 10 are installed at the bottom of the serum processing tube 6. The blood filtration membrane gasket 13 is treated with anti-erythrocyte antibodies and its function is to filter erythrocytes. After the erythrocytes are removed by the blood filtration membrane gasket 13, pure serum is obtained. At this time, the serum is temporarily stored in the serum processing tube 6. A tube cap 3 is installed at the top of the vacuum storage tube 5, and the inside of the tube cap 3 is... With an inner plug 4, a blood collection needle 1 is inserted into an animal vein to collect blood. The blood collected by the blood collection needle 1 is introduced through a connected tubing 2 into a vacuum storage tube 5, which is equipped with a tube cap 3 and an inner plug 4 at the top. Automatic blood collection is achieved by utilizing the negative pressure formed by the built-in groove 11 in the vacuum storage tube 5. The anticoagulant in the built-in groove 11 prevents blood coagulation and ensures the effectiveness of subsequent processing. A connecting component 8 for rapid blood guidance is installed between the vacuum storage tube 5 and the serum processing tube 6. The connecting component 8 includes an inner locking groove 801 and an outer locking plate 802. The outer locking plate 802 is slidably installed inside the inner locking groove 801. The detection card body 7 is located at the bottom of the serum processing tube 6. In the initial state of the device, the vacuum storage tube 5 is in good working order. When the vacuum storage tube 5 is not rotated, the inner locking groove 801 is engaged and fixed at one end of the outer locking plate 802. At this time, the bottom opening of the inner groove 11 is tightly fitted with the sealing gasket 12 with silicone on its surface. The vacuum storage tube 5 and the serum processing tube 6 are in a sealed isolation state. When the vacuum storage tube 5 is rotated, the inner locking groove 801 first releases the engagement with one end of the outer locking plate 802 as it rotates. After rotating to the position, the other end of the inner locking groove 801 engages and positions with the other end of the outer locking plate 802, realizing rotation locking and flow path connection. At this time, the bottom opening of the inner groove 11 is disengaged from the sealing gasket 12, and the inner groove 11 is connected to the serum processing tube 6. The blood in the vacuum storage tube 5 flows into the serum processing tube 6.
[0017] like Figure 1 and Figure 3As shown, the test card body 7 has an auxiliary component 9 for blood testing. The auxiliary component 9 includes a slot 901 and a needle 902. The needle 902 is located inside the slot 901. An observation window 14 is installed on the side of the test card body 7 near the auxiliary component 9. There are two sets of observation windows 14. The user can press down on the entire serum processing tube 6, and the serum processing tube 6 will move along the inside of the slot 901. At the same time, the aluminum foil 10 at the bottom of the serum processing tube 6 will be punctured by the hard plastic needle 902 inside the slot 901. Then, the serum in the serum processing tube 6 will flow into the slot 901 on the test card body 7, completing the test. Blood collection and serum processing are completed. The integrated design of physiology and detection greatly simplifies the operation process, eliminating the need for separate instruments such as blood collection needles, centrifuge tubes, and test cards, as well as the need for manual transfer of blood or serum. This effectively reduces the difficulty and workload for operators, while avoiding problems such as blood contamination and serum loss during transfer, thus improving detection efficiency. The device achieves automatic negative pressure blood collection through the cooperation of blood collection needle 1, tubing 2, and vacuum storage tube 5. The rotation locking design of connecting component 8 ensures precise flow path conduction and sealing. The needle 902 of auxiliary component 9, in conjunction with aluminum foil 10, enables rapid serum introduction. The synergistic effect of all components allows the entire detection process to be completed quickly, adapting to the needs of rapid on-site testing.
[0018] In summary, this integrated blood collection and testing card device firstly... Figures 1-5 In the structure shown, during use, the vacuum storage tube 5 and the serum processing tube 6 are sealed and isolated by the connecting component 8. The inner slot 801 of the connecting component 8 engages and is fixed with one end of the outer plate 802, so that the bottom opening of the inner groove 11 of the vacuum storage tube 5 is tightly fitted with the sealing gasket 12 with silicone on its surface, ensuring that the negative pressure environment inside the vacuum storage tube 5 does not leak, and at the same time preventing blood from flowing into the serum processing tube 6 in advance. The two sets of aluminum foils 10 at the bottom of the serum processing tube 6 are in a completely sealed state to prevent the serum from leaking after subsequent processing. The auxiliary component 9 in the detection card body 7 remains in its initial position, the needle 902 is not in contact with the aluminum foil 10, and the entire device is in a standby state. During the blood collection stage, the operator inserts the blood collection needle 1 into the animal's vein. Due to the pre-formed negative pressure in the built-in groove 11 of the vacuum storage tube 5, the collected blood will be introduced into the vacuum storage tube 5 through the hose 2 connected to the blood collection needle 1 and the inner plug 4 inside the tube cap 3, thus achieving automatic blood collection. At the same time, the anticoagulant pre-placed in the built-in groove 11 will come into full contact with the flowing blood, effectively preventing blood coagulation and providing a guarantee for subsequent serum separation and testing. Furthermore, the central axis of the built-in groove 11 inside the vacuum storage tube 5 does not coincide with the central axis of the vacuum storage tube 5. This structural design can further optimize the negative pressure blood collection effect, ensuring smooth blood flow and minimal residue. During the blood processing stage, after blood collection, the operator rotates the vacuum storage tube 5. As the vacuum storage tube 5 rotates, the inner slot 801 of the connecting component 8 will first disengage from one end of the outer slot 802. After continuing to rotate to the preset position, the other end of the inner slot 801 engages with the other end of the outer slot 802, achieving rotational locking while simultaneously causing the bottom opening of the built-in groove 11 to disengage from the sealing gasket 12. At this time, the vacuum storage tube 5 and the serum processing tube 6 are interconnected. Under the action of its own gravity and residual negative pressure, the blood in the vacuum storage tube 5 slowly flows into the serum processing tube 6. The serum processing tube 6 is equipped with a blood filter membrane gasket 13 treated with anti-erythrocyte antibodies. When the blood flows through the blood filter membrane gasket 13, the erythrocytes are effectively filtered. After removal, pure serum is obtained and temporarily stored in serum processing tube 6 to prepare for subsequent testing. The sealing gasket 12 is integrated with the serum processing tube 6, and the diameter of the sealing gasket 12 is smaller than the diameter of the serum processing tube 6. This design ensures the initial sealing effect without affecting the smooth flow of blood. During the testing phase, the operator presses down on the entire serum processing tube 6, and the serum processing tube 6 moves smoothly along the slot 901 of the auxiliary component 9 inside the test card body 7. During this process, the two sets of aluminum foil 10 at the bottom of the serum processing tube 6 are punctured by the hard plastic needle 902 inside the slot 901. The pure serum temporarily stored in the serum processing tube 6 flows into the slot 901 of the test card body 7 through the punctured aluminum foil 10 openings. After the serum reacts with the test reagent inside the test card, the operator can clearly observe the reaction results through the two sets of observation windows 14 set on the test card body 7, thus completing the entire blood collection and testing process.
