Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a sterile anticoagulant tube for testing synovial fluid. Background Technology

[0002] Anticoagulant tubes are medical test tubes treated with anticoagulants, primarily used to prevent blood samples from clotting and ensure the accuracy of medical tests and biological experiments. They are distinguished by different colors to indicate the type of anticoagulant and its use: purple cap tubes use EDTA to chelate calcium ions to block coagulation and are suitable for routine blood tests; green cap tubes add heparin to inhibit thrombin activity and are used for blood gas analysis and biochemical tests; blue cap sodium citrate tubes are specifically used for coagulation function tests.

[0003] For example, an anticoagulant blood collection tube with application number "CN202421239713.9" includes: a tube body configured to hold a blood sample; a cap detachably mounted at the opening of the tube body; a drug-injecting element on the cap, penetrating the cap; a drug-injecting channel on the drug-injecting element; and a drug-carrying cap rotatably connected to the cap. The drug-carrying cap includes a cavity and multiple drug-filled chambers. When the cap and the drug-carrying cap are connected, one end of the drug-injecting element is located within the cavity. By rotating the drug-carrying cap, one end of the drug-injecting element penetrates into one of the drug-filled chambers, and the drug in the chamber flows through the drug-injecting channel into the tube body. Each rotation completes the addition of anticoagulant to one drug-filled chamber. Thus, even if the blood volume of the collected blood sample does not meet the testing requirements, the blood collection personnel can accurately add the appropriate unit of anticoagulant according to the blood volume, ensuring that the anticoagulant and the collected blood are handled in a standard ratio.

[0004] Based on the aforementioned existing technology, it is known that when using existing anticoagulant tubes, a stopper with a diameter slightly larger than the opening of the test tube is directly inserted into the anticoagulant tube, and the test tube body's elasticity is used for restraint. However, this restraint method has poor sealing performance, and if the test tube is squeezed, the stopper can easily fall out of the anticoagulant tube, causing leakage of synovial fluid and other substances inside. Utility Model Content

[0005] This utility model provides a sterile anticoagulant tube for testing synovial fluid, which solves the problem that existing anticoagulant tubes, when used, mostly use a stopper with a diameter slightly larger than the test tube opening directly inserted into the anticoagulant tube, relying on the elasticity of the test tube body for restraint. However, this restraint method has poor sealing performance, and if the test tube is squeezed, the stopper can easily fall out of the anticoagulant tube, causing leakage of synovial fluid and other substances inside.

[0006] The present invention adopts the following technical solution: a sterile anticoagulant tube for testing synovial fluid, comprising a tube body structure, wherein the tube body structure is a flexible and transparent structure, and the tube body structure is pre-filled with anticoagulant fluid;

[0007] A connecting strap is fixedly connected to the rear side of the outer peripheral surface of the tube body mechanism, and the connecting strap is a flexible structure.

[0008] A top cover plate is fixedly connected to the side of the connecting strip away from the tube body mechanism. A sealing plug is fixedly connected to the bottom surface of the top cover plate. The sealing plug is a solid structure. An outer sealing ring A and an outer sealing ring B are fixedly connected to the outer side of the sealing plug.

[0009] A further technical solution is that the outer periphery of the tube body mechanism is provided with a liquid level scale, and an upper baffle is fixedly connected to the top of the outer periphery of the tube body mechanism.

[0010] In a further technical solution, the diameter of the upper baffle is larger than that of the tube body mechanism, and an annular groove is provided on the top surface of the upper baffle, which is an upper sealing groove.

[0011] In a further technical solution, an inner sealing groove is provided on the inner wall of the tube body mechanism, and there are two inner sealing grooves in total.

[0012] In a further technical solution, the two inner sealing grooves are arranged in a straight line array on the inner wall of the tube body mechanism, and a support base is sleeved at the bottom end of the tube body mechanism.

[0013] In a further technical solution, the support base is a flexible structure, and an insertion groove for inserting the tube mechanism is provided on the top surface of the support base.

[0014] In a further technical solution, a suction cup assembly is fixedly connected to the bottom surface of the support base, and the suction cup assembly and the support base together form an auxiliary support structure for the tube mechanism.

[0015] In a further technical solution, an upper sealing ring is fixedly connected to the bottom end face of the upper cover plate, the upper sealing ring matches the upper sealing groove, and the upper sealing ring is located outside the sealing plug.

[0016] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0017] Firstly, this invention fundamentally solves the sealing and leakage prevention problems through an innovative multi-seal structure design. Specifically, the outer sealing rings A and B on the outside of the sealing plug fit into the inner sealing groove on the inner wall of the tube body, forming a double physical seal inside the tube body. This effectively prevents synovial fluid from seeping out from the gap between the tube body and the sealing plug. At the same time, the upper sealing ring at the bottom of the upper cover plate engages with the upper sealing groove of the upper baffle, forming an additional sealing barrier at the top of the tube body, further blocking the leakage path. The synergistic effect of the multiple sealing structures completely prevents the plug from coming out when the tube body is squeezed, ensuring the integrity of the synovial fluid sample. In addition, the flexible structure design of the connecting strip not only allows it to deform flexibly with the pulling of the upper cover plate, but also keeps the upper cover plate and the tube body always connected, preventing the upper cover plate from being lost after opening, further improving the reliability and continuity of operation.

[0018] Secondly, this invention achieves innovative optimization of support stability through the combination of a support base and a suction cup assembly: the flexible structure of the support base forms a wrap-around buffer support for the tube body, reducing damage to the tube body from external impacts; the insertion groove at its top precisely limits the position of the tube body, preventing the tube body from swaying within the support base; while the suction cup assembly firmly fixes the support base to the placement plane through adsorption, further improving the placement stability of the tube body and completely solving the problem of the anticoagulant tube easily tipping over. At the same time, the flexible and transparent structure of the tube body allows operators to directly observe the mixing state of the internal synovial fluid and anticoagulant fluid, and promptly judge the anticoagulant effect; the liquid level scale on its outer circumference can accurately display the amount of synovial fluid injected, avoiding the impact of insufficient or excessive sample volume on the test results, providing a clear basis for subsequent test operations, and significantly improving the convenience and accuracy of use.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0029] Reference Figures 1 to 5 As shown, this utility model embodiment provides a sterile anticoagulant tube for joint fluid testing, with tube body 1, which is a flexible and transparent structure, and the tube body 1 is pre-filled with anticoagulant fluid.

[0030] A connecting band 3 is fixedly connected to the rear side of the outer peripheral surface of the tube body 1. The connecting band 3 is a flexible structure.

[0031] A top cover plate 301 is fixedly connected to the side of the connecting band 3 away from the tube body mechanism 1. A sealing plug 3012 is fixedly connected to the bottom end face of the top cover plate 301. The sealing plug 3012 is a solid structure. An outer sealing ring A3013 and an outer sealing ring B3014 are fixedly connected to the outside of the sealing plug 3012. The tube body mechanism 1 is a flexible and transparent structure for easy observation. The pre-filled anticoagulant can directly achieve anticoagulation of synovial fluid. The connecting band 3 can prevent the top cover plate 301 from being lost. The outer sealing rings A3013 and B3014 on the outside of the sealing plug 3012 can initially improve the sealing performance.

[0032] like Figure 2As shown, specifically, a liquid level scale 101 is provided at the front end of the outer periphery of the tube body mechanism 1, and an upper baffle 1011 is fixedly connected to the top end of the outer periphery of the tube body mechanism 1. The liquid level scale 101 on the outer periphery of the tube body mechanism 1 can clearly read the synovial fluid volume and provide a reference value for testing. The upper baffle 1011 at the top end of the tube body mechanism 1 can protect the top structure and also provide a basis for the sealing structure.

[0033] like Figure 1 As shown, specifically, the diameter of the upper baffle 1011 is larger than that of the tube body mechanism 1, and an annular groove is provided on the top surface of the upper baffle 1011. This annular groove is the upper sealing groove 1012. The diameter of the upper baffle 1011 is larger than that of the tube body mechanism 1, which expands the top protection range. The upper sealing groove 1012 at the top of the upper baffle 1011 can cooperate with the corresponding component to further improve the sealing performance of the tube body mechanism 1.

[0034] like Figure 5 As shown, specifically, an inner sealing groove 1013 is provided on the inner wall of the tube body mechanism 1. There are two inner sealing grooves 1013. The two inner sealing grooves 1013 on the inner wall of the tube body mechanism 1 can fit with the outer sealing ring A3013 and the outer sealing ring B3014. This fit can form a double seal on the inner wall of the tube body, reducing the problem of joint fluid leakage.

[0035] like Figure 2 As shown, specifically, two inner sealing grooves 1013 are arranged in a straight line on the inner wall of the tube body mechanism 1. A support base 2 is fitted at the bottom of the tube body mechanism 1. The two inner sealing grooves 1013 are arranged in a straight line to make the sealing ring and the groove fit more evenly and the sealing more stable. The support base 2 at the bottom of the tube body mechanism 1 can prevent the tube from tipping over due to an unstable center of gravity.

[0036] like Figure 3 As shown, specifically, the support base 2 is a flexible structure, and an insertion groove 201 for inserting the tube mechanism 1 is provided on the top surface of the support base 2. The flexible support base 2 can buffer external impacts and reduce damage to the tube mechanism 1. The insertion groove 201 at the top of the support base 2 can accurately limit the position of the tube mechanism 1 and improve its placement stability.

[0037] like Figure 2 As shown, specifically, a suction cup assembly 2011 is fixedly connected to the bottom surface of the support base 2. The suction cup assembly 2011 and the support base 2 together form an auxiliary support structure for the tube body mechanism 1. The suction cup assembly 2011 at the bottom of the support base 2 can tightly adhere to the plane to make the base more firmly fixed. The auxiliary support structure formed by the suction cup assembly 2011 and the support base 2 can enhance the stability of the tube body mechanism 1.

[0038] like Figure 1As shown, specifically, an upper sealing ring 3011 is fixedly connected to the bottom end face of the upper cover plate 301. The upper sealing ring 3011 matches the upper sealing groove 1012. The upper sealing ring 3011 is located outside the sealing plug 3012. The upper sealing ring 3011 at the bottom end of the upper cover plate 301 matches the upper sealing groove 1012 and is located outside the sealing plug 3012. This can form a multiple seal with other sealing components, greatly improving the overall sealing performance.

[0039] In use, first, align the bottom end of the tube body 1 with the insertion slot 201 at the top of the support base 2, and slowly insert it until the bottom of the tube body 1 is in contact with the bottom of the insertion slot 201. The flexible structure of the support base 2 forms a wrapping initial support for the tube body 1. Then, press the suction cup assembly 2011 at the bottom of the support base 2 to expel the air between the suction cup assembly 2011 and the placement surface, so that the suction cup assembly 2011 is tightly attached to the placement surface. Through the synergistic effect of the support base 2 and the suction cup assembly 2011, the tube body 1 is placed stably, preventing the tube from tipping over during subsequent operations.

[0040] Then, holding the top cover plate 301 away from the side of the connecting strip 3, pull the top cover plate 301 upward in the direction away from the opening of the tube body mechanism 1; since the connecting strip 3 is a flexible structure, the connecting strip 3 undergoes adaptive deformation under the action of tension. Continue to pull until the sealing plug 3012 is completely separated from the opening of the tube body mechanism 1. At this time, stop pulling. The tube body mechanism 1 is in an open state where joint fluid can be injected, and the connecting strip 3 can prevent the top cover plate 301 from being lost.

[0041] Then, the synovial fluid to be tested is slowly injected into the tube body 1. During the injection process, the amount of synovial fluid injected is observed through the liquid level scale 101 on the front end of the outer periphery of the tube body 1 to ensure that the injection amount meets the testing requirements. At the same time, the anticoagulant pre-filled inside the tube body 1 comes into natural contact with the injected synovial fluid and mixes thoroughly. The anticoagulant blocks the coagulation process of the synovial fluid, achieving anticoagulation treatment of the synovial fluid and providing a qualified sample for subsequent testing.

[0042] After the synovial fluid is injected, the upper cover plate 301 is pushed in the opposite direction towards the opening of the tube body 1, so that the sealing plug 3012 is gradually inserted into the opening of the tube body 1. During this process, the outer sealing ring A3013 and outer sealing ring B3014 on the outside of the sealing plug 3012 respectively engage with the two inner sealing grooves 1013 opened on the inner wall of the tube body 1, forming a double sealing structure inside the tube body. At the same time, the upper sealing ring 3011 fixed at the bottom of the upper cover plate 301 engages with the upper sealing groove 1012 opened on the upper baffle 1011 at the top of the tube body 1, forming an additional sealing structure at the top of the tube body. The upper cover plate 301 is continuously pushed until the bottom of the upper cover plate 301 is completely attached to the top of the upper baffle 1011, completing the all-round sealing of the tube body 1 and preventing leakage of internal synovial fluid.

[0043] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
