Description

TECHNICAL FIELD

[0001] The utility model relates to the medical examination related technical field especially, a kind of multi-anticoagulant blood collection tube for examination. BACKGROUND

[0002] In the field of modern medical examination, the collection and processing of blood samples are crucial links.

[0003] Traditional blood collection tubes are usually composed of a plastic tube body, a tube extractor and a cap. The tube body may contain different additives, such as anticoagulants or coagulants, to meet different testing needs. For example, red cap blood collection tubes do not contain additives and are used for routine serum biochemical tests; purple cap blood collection tubes contain EDTANa2 anticoagulant and are used for routine blood tests; blue cap blood collection tubes contain sodium citrate anticoagulant and are used for coagulation mechanism tests. The working principle of blood collection tubes is based on negative pressure suction, which generates negative pressure through the tube extractor to make blood flow into the tube.

[0004] Some existing technologies provide some solutions for the improvement of blood collection tubes, such as Chinese patent CN112359091A discloses a whole blood free DNA preservative, a vacuum blood collection tube and a preparation method thereof. The patent discloses a formula of a whole blood free DNA preservative, as well as a vacuum blood collection tube containing the preservative and a preparation method thereof.

[0005] Some patents focus on solving the delivery problem of blood collection tubes, such as Chinese patent CN112660740A discloses an expandable blood collection tube specimen transmission system, which includes a window track, a lifting device, a belt lifting track, an aerial track and a slow descent track, aiming to realize mechanical delivery of blood collection tubes and improve the universality of the system.

[0006] In actual use, different test items have different requirements for blood samples, including whole blood, serum and plasma, which requires different blood collection tubes to be matched. For example, biochemical tests, routine blood tests and microbiological tests require blood collection tubes with different color markings, and each color of blood collection tube contains different additives.

[0007] On the other hand, in order to shorten the time to issue test results (TAT), different blood collection tubes need to be sent to different instruments at the same time for simultaneous testing, which requires medical staff to change multiple blood collection tubes when collecting blood. During the blood collection process, medical staff need to select the correct blood collection tube according to the different test items, and ensure that the blood collection tube is firmly connected to the needle to avoid blood leakage caused by the blood collection tube detaching from the needle.

[0008] However, frequent replacement of blood collection tubes during blood collection can increase the discomfort of patients. Moreover, the replacement of blood collection tubes during blood collection, the withdrawal of venipuncture needles during blood collection, and other links are high-risk links that cause needle stick injuries of nursing staff. Especially when multiple blood collection tubes are used for blood collection, improper operation can also cause blood leakage or specimen contamination. Utility model content

[0009] The utility model aims at providing a multi-anticoagulant blood collection tube for inspection to overcome the shortcomings of the prior art.

[0010] The utility model discloses the scheme as follows:

[0011] A multi-anticoagulant blood collection tube for inspection includes a tube body, the tube body includes a cap and a concentric outer sleeve and inner sleeve, the cap and the outer sleeve are connected through threads;

[0012] The inner sleeve is internally provided with a plurality of sealed cavities, and different cavities are separated by a partition plate.

[0013] And, the same or different anticoagulants are arranged in different cavities.

[0014] The core design of the utility model is that the tube body is composed of a cap and concentric outer sleeve and inner sleeve, and is connected through threads. The inner sleeve is internally designed with a plurality of sealed cavities, and the cavities are separated from each other by a partition plate, so that the same or different anticoagulants can be loaded in different cavities. The principle of this design is to integrate multiple anticoagulants in one blood collection tube to meet different inspection requirements, reduce the number of blood collection tube replacement during blood collection, and improve blood collection efficiency.

[0015] In some embodiments, as a further preferred scheme, the top of the outer sleeve is capped by a rubber plug, and one or more puncture points are arranged on the rubber plug.

[0016] Such a design ensures the sealing of the blood collection tube, and the puncture points provide a direct access to the blood sample. At the same time, such a design allows the blood sample to directly enter the inside of the blood collection tube through the puncture points, mix with the corresponding anticoagulant, and provide convenience for subsequent inspection.

[0017] In some embodiments, as a further preferred scheme, the inner sleeve is nested into the outer sleeve from the bottom of the outer sleeve, and the bottom of the inner sleeve is closed, and the openings of different cavities at the top of the inner sleeve are all located below the rubber plug.

[0018] The above scheme provides the design details of the inner sleeve, i.e. the inner sleeve is nested into the outer sleeve from the bottom of the outer sleeve, and the bottom of the inner sleeve is closed, and the different lumen openings at the top are all located below the rubber plug. The effect of this structure is to form a compact blood collection tube, in which the different lumen openings of the inner sleeve can be aligned with the puncture points on the rubber plug, so that the blood sample can directly enter the corresponding lumen through the puncture points. Such a design not only maintains the vacuum state of the blood collection tube, but also ensures the accuracy and hygiene of the blood sample collection and distribution process.

[0019] In some embodiments, as a further preferred scheme, the different lumens in the inner sleeve and the space below the rubber plug of the outer sleeve are designed to be vacuum.

[0020] In the above scheme, the different lumens in the inner sleeve and the space below the rubber plug of the outer sleeve are designed to be vacuum. The effect of this design is to use vacuum negative pressure to promote the collection of blood samples, so that blood automatically flows into the corresponding lumen under the action of negative pressure and mixes with anticoagulant, thereby reducing manual operation, improving blood collection efficiency, and ensuring sample stability and anticoagulation effect.

[0021] In some embodiments, as a further preferred scheme, the inner sleeve is rotated by the adjusting screw connected to the outer sleeve to make the different lumen openings reach below the puncture points.

[0022] The above scheme allows the operator to control the opening position of the different lumens in the inner sleeve by rotating the adjusting screw, accurately aligning the puncture points, and thus realizing blood collection of different lumens. This rotation mechanism provides a simple method to select and access individual lumens, improving the flexibility and accuracy of the blood collection process.

[0023] In some embodiments, as a further preferred scheme, the inner sleeve adopts a tapered structure near the adjusting screw.

[0024] Due to the adoption of the above scheme, when the adjusting screw is rotated, the tapered portion of the inner sleeve can smoothly pass below the rubber plug, reducing friction and resistance, making rotation more smooth. In addition, the tapered structure also helps to ensure the stability of the inner sleeve during rotation, avoiding displacement or leakage of the inner sleeve during operation, thereby ensuring the accuracy and safety of the blood collection process.

[0025] In some embodiments, as a further preferred scheme, the puncture points are arranged eccentrically on the rubber plug.

[0026] The effect of this design is to avoid the backflow of blood or cross contamination when the puncture point is aligned with the center of the lumen. By setting the eccentric position, it can ensure that the blood sample flows directly into the specific lumen during collection, reducing the contact between the blood sample and other parts of the blood collection tube, thereby improving the purity of the sample and the accuracy of the test.

[0027] In some embodiments, as a further preferred solution, an indication label is provided on the outer sleeve to indicate the eccentric position of the puncture point. Correspondingly, a classification label is provided at the bottom of the inner sleeve to position the indication label, which is marked with the corresponding lumen or anticoagulant in the inner sleeve by color, text or pattern.

[0028] In the above solution, the position of the puncture point is displayed by the indication label, and the classification label indicates which lumen the puncture point is located above. This solution provides a clear and intuitive way to identify and distinguish the contents of different lumens in the inner sleeve, so that medical personnel can quickly select the appropriate blood collection tube for testing. The design of this classification label improves the identification efficiency of the blood collection tube and ensures the accuracy of the blood collection and testing process.

[0029] In some embodiments, as a further preferred solution, the anticoagulant includes one of heparin, EDTA-K2 salt, citric acid, and sodium oxide.

[0030] Different anticoagulants are suitable for different blood test items, such as EDTA for routine blood test and blood type identification, and heparin for blood gas analysis. This diverse selection of anticoagulants ensures that the blood collection tube can be widely used in various clinical tests, improving the versatility and practicality of the blood collection tube.

[0031] Advantages and beneficial effects of the present application:

[0032] Compared with the prior art, the multi-anticoagulant blood collection tube of the present application has many significant advantages, mainly in improving the blood collection efficiency and flexibility of sample processing. First, by separating multiple lumens containing different anticoagulants in a single blood collection tube, medical personnel can select the appropriate lumen for blood collection according to the testing requirements, avoiding the inconvenience of frequent replacement of blood collection tubes in the traditional blood collection process. This design not only saves time and resources, but also reduces the discomfort of patients due to multiple punctures, while also reducing the complexity of operation and the error rate of medical personnel.

[0033] Secondly, the blood collection tube of the utility model realizes the accurate control to different tube cavities through the puncture point on the rubber plug on the top of the outer sleeve and the rotation adjustment mechanism of the inner sleeve. The design of the eccentric puncture point and the indication label enables medical staff to quickly and accurately identify and puncture the correct tube cavity, thereby improving the accuracy of blood collection and sample quality. In addition, the cooperation of the tapered structure of the inner sleeve and the adjusting thread makes the rotation alignment of the tube cavity more smooth, enhancing the stability and durability of the blood collection tube.

[0034] Finally, the classification label and diversified anticoagulant selection of the blood collection tube of the utility model further improve the convenience and accuracy of the blood collection process. The classification label clearly marks different tube cavities or anticoagulants through color, text or pattern, so that medical staff can quickly identify and select the appropriate blood collection tube. The diversified anticoagulant selection ensures that the blood collection tube can meet the needs of various clinical tests, improving the versatility and practicality of the blood collection tube. In general, the design of the blood collection tube of the utility model provides an efficient, safe and user-friendly blood collection solution for clinical tests through its innovative structure and function.

DETAILED DESCRIPTION

[0041] The preferred embodiments of the present application will be described in detail below, so as to make the purpose, characteristics and advantages of the present application more clearly understood. It should be understood that the following embodiments are not a limitation on the scope of the present application, but only to illustrate the essential spirit of the technical scheme of the present application.

[0042] In the following description, for the purpose of illustrating various disclosed embodiments, specific details are set forth in order to provide a thorough understanding of various disclosed embodiments. However, one skilled in the relevant arts will recognize that embodiments can be practiced without one or more of the specific details, or with other methods, components, materials, and so forth. In other instances, well-known methods associated with the application have not been described in detail in order to avoid unnecessarily obscuring the description.

[0043] Reference throughout this specification to "an embodiment" or "the embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearances of the phrase "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. In addition, particular features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0044] First as shown in Figure 1 , in one embodiment of the present application, the tube body 1 and the blood collection needle assembly 2 constitute a complete blood collection kit, wherein the tube body 1 is composed of a cap 101 and a tube body 1 composed of a concentric outer sleeve 102 and an inner sleeve 103. The cap 101 is connected with the outer sleeve 102 through threads, ensuring the sealing of the blood collection tube, and the top of the outer sleeve 102 is capped by a rubber plug 3, and a fixed and eccentric puncture point 4 is arranged on the rubber plug 3, as shown in Figure 2 .

[0045] As can be seen from Figure 3 , the inner sleeve 103 is nested in the outer sleeve 102 from the bottom of the outer sleeve 102, and the bottom of the inner sleeve 103 is closed, and the opening at the top is below the rubber plug 3, so as to maintain the vacuum state in the tube cavity.

[0046] The blood collection needle assembly 2 includes a blood collection needle 201 and a venipuncture needle 202, and the blood collection needle 201 is used to collect and deliver blood into the inner sleeve 103.

[0047] The inner sleeve 103 is designed with several sealed cavities inside, which are separated by partition plates to prevent mixing between different anticoagulants. In these cavities, the same or different anticoagulants can be loaded as needed, such as heparin, EDTA-K2 salt, citric acid, sodium oxide, etc., to meet different testing needs.

[0048] In Figure 3In the embodiment, the inner sleeve 103 is divided into three lumens, namely, the first lumen 102a, the second lumen 102b and the third lumen 103c, which are filled with heparin (blood gas, serum biochemistry), EDTA-K2 salt (blood routine) and citric acid (blood clotting, blood sedimentation) respectively. By filling these anticoagulants in different lumens, the blood collection tube can meet the needs of a wide range of clinical tests, and improve the applicability and practicability of the blood collection tube.

[0049] It should be noted that the different lumens in the inner sleeve 103 and the space below the rubber plug 3 where the outer sleeve 102 is located are in a vacuum state. The vacuum state in the lumens can be formed by extracting the internal air after puncturing the rubber plug 3.

[0050] As shown in Figure 3 and Figure 4 , the inner sleeve 103 is rotated by the adjusting thread 104 connected to the outer sleeve 102 to make the different lumens open below the puncture point 4. For example, in the first lumen 102a, the second lumen 102b and the third lumen 103c in Figure 3 , the inner sleeve 103 and the outer sleeve 102 are rotated by 120° to make the puncture point 4 switch from above the lumen to above another lumen.

[0051] In order for the operator to quickly determine the type of anticoagulant in each lumen, an indication sticker 5 is provided on the outer sleeve 102 to indicate the eccentric position of the puncture point 4. Classification stickers are provided at the bottom of the inner sleeve 103 to position the indication sticker 5. These classification stickers are marked with the corresponding lumen or anticoagulant in the inner sleeve 103 by color, text or pattern.

[0052] In practice, as shown in Figure 5 , the position of the indication sticker 5 shows the eccentric direction of the puncture point 4, i.e. the position of the blood collection needle 201, and when the indication sticker 5 is aligned with the classification sticker at the bottom of the inner sleeve 103, the blood collection needle 201 is located above the lumen indicated by the classification sticker. In Figure 5 , the indication sticker 5 is aligned with the classification sticker 103a, and the blood collection needle 201 collects blood in the lumen corresponding to the classification sticker 103a, without deviating to the lumen corresponding to the adjacent classification sticker 103b.

[0053] The parts not described in the utility model are known to those skilled in the art.

[0054] The basic principle and main features of the present application and the advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
