Description

[0002] The IMMAGE800 specific protein analysis system instrument produced by Beckman company is a kind of high-precision, automated medical equipment, and its core function is to generate turbidity by antigen-antibody binding reaction to carry out the quantitative analysis of sample.The working principle of the system is very precise, and the operation process is simple and efficient: the user only needs to pour the serum sample to be measured into the special UDR reagent box, then the reagent box is placed in the instrument, and the instrument will automatically execute a series of complex steps, including the combination of serum and the measured material, turbidity generation and final determination analysis.This fully automated processing mode greatly improves the detection efficiency and accuracy, so that IMMAGE800 is widely used in the field of medical diagnosis.

[0003] The UDR reagent box is a special consumable of the equipment, and its design strictly matches the parameters of the instrument, to ensure the accuracy and stability of analysis.However, this specificity also leads to the non-substitutability of the reagent box, which brings inconvenience to the user in certain circumstances.

[0004] When the amount of serum sample to be measured is small, after pouring into the UDR reagent box, the liquid level is often very shallow, which directly affects the effective work of the probe in the instrument.Because the probe is designed with a certain operation height and range, the too shallow liquid level can easily cause the probe to fail to accurately suck enough serum sample, thereby making the entire determination process impossible, which seriously affects the continuity and accuracy of detection.

[0005] To solve this problem, the traditional solution often adopts two strategies: one is to directly discard the small amount of serum remaining in the UDR reagent box and replace a new reagent box to re-determine;The second is to supplement the same batch of serum sample into the reagent box to ensure that the liquid level reaches the height that the probe can suck.However, both methods have obvious disadvantages.The former causes waste of expensive serum resources and increases detection cost.The latter may increase the risk of detection error due to repeated use and cross contamination of serum samples.

[0032] The following describes the serum placement device of the present application. Figures 1-5 The serum placement device of the present application is described below.

[0033] The serum placement device provided by the embodiment of the present application comprises a reagent box 1 and a first reagent tube 2. The top surface of the reagent box 1 is provided with a placement hole 16, and the outer diameter size of the first reagent tube 2 matches the inner diameter size of the placement hole 16, so as to realize the stable clamping between the first reagent tube 2 and the reagent box 1. The first reagent tube 2 is clamped in the placement hole 16, so as to ensure that it will not fall into the inside of the reagent box 1 due to external force or vibration, and the pollution and loss of the serum sample are avoided. The embodiment of the present application can reduce the loss of the reagent box 1 by replacing the first reagent tube 2.

[0034] As shown in Figure 2 The first reagent tube 2 comprises a tube body, and the tube body is provided with clear scales or marks, so as to accurately measure the volume of the serum sample. The tube body comprises a first tube body 21 and a second tube body 22, and the first tube body 21 communicates with the second tube body 22. The first tube body 21 is located at the top of the second tube body 22, the cross section of the top of the second tube body 22 is the same as the bottom cross section of the first tube body 21, the cross section area of the second tube body 22 decreases from the top of the second tube body 22 to the bottom of the second tube body 22, and the structure is a tapered structure which is gradually tapered. The structure is flat relative to the bottom, which facilitates the extension of the instrument probe into the tube body, accurately sucks the serum sample, saves the serum, guarantees the continuity of detection, and further improves the accuracy of the detection result. The first tube body 21 and the second tube body 22 can be an integral structure. In an embodiment, the volume of the first reagent tube 2 is 2ml, and can also be 3ml, 6ml, etc.

[0035] The serum placement device provided by the embodiment of the present application further comprises a buffer, which is arranged on the inner wall surface of the placement hole 16. The buffer not only protects the first reagent tube 2, but also plays a sealing and limiting role, so as to prevent the first reagent tube 2 from sliding or falling off and affecting the detection result.

[0036] The serum placement device provided by the embodiment of the present application further comprises a cable 3, as shown in Figure 3As shown, one end of the cable 3 is connected with the first reagent tube 2, and the other end of the cable 3 is connected with the reagent box 1. In actual operation, one end of the cable 3 can be fixedly connected with the first reagent tube 2 by winding or knotting, and in the case that the first reagent tube 2 is clamped in the placement hole 16, the other end of the cable 3 can also be fixedly connected with the reagent box 1 by winding or knotting, which can prevent the first reagent tube 2 from falling into the reagent box 1 during testing, and on the other hand, after use, the user can take out the first reagent tube 2 through the cable 3, that is, loosen the connection between the cable 3 and the reagent box 1, and take out the first reagent tube 2 by external force.

[0037] The cable 3 in the embodiment of the utility model comprises a wool rope, which is convenient to obtain, easy to use and improves the practicability of the device.

[0038] The placement hole 16 in the embodiment of the utility model is multiple, such as 2, 3, 5, 6 and the like. The first reagent tube 2 is multiple, such as 2, 3, 5, 6 and the like. The cable 3 is also multiple, such as 2, 3, 5, 6 and the like. For example, Figure 4 and Figure 5 As shown, the placement hole 16 is 2, the first reagent tube 2 is 2, and the cable 3 is also 2. The embodiment of the utility model can detect and analyze multiple samples at a time by arranging multiple placement holes 16, multiple cables 3 and multiple first reagent tubes 2.

[0039] As shown, Figure 2 The first reagent tube 2 also comprises an end cover 23, the end cover 23 covers the opening of the tube body of the first reagent tube 2 and is used for sealing the first reagent tube 2. Specifically, the end cover 23 comprises a cover body and a sealing part (not marked in the figure), the cover body is arranged at the top port of the first tube body 21, and the outer periphery of the cover body can be circular or polygonal, and the specific shape depends on the specific requirements and functional requirements of the design of the first reagent tube 2. When the end cover 23 is closed, the cover body completely covers the opening of the first reagent tube 2, that is, the size of the cover body is greater than the size of the placement hole 16, so as to prevent falling into the reagent box 1. The sealing part is annularly arranged on the bottom surface of the cover body along the axis of the cover body, and there is a spacing between the outer periphery of the sealing part and the outer periphery of the cover body, so as to ensure that the sealing part can be compressed tightly during installation and form an effective seal with the inner wall of the tube body. Specifically, the sealing part can be designed by using an elastic material (such as silica gel or rubber) to provide a good sealing effect.

[0040] In actual use, the end cover 23 is inserted into the opening of the tube body, and the outer wall surface of the sealing part is tightly combined with the inner wall surface of the tube body (the first tube body 21), so that the sample in the first reagent tube 2 cannot leak, and the outside pollutants cannot enter the tube during storage, thereby ensuring the integrity of the sample. Further, at least part of the bottom surface of the end cover 23 is combined with the top end surface of the tube body (the first tube body 21), and the sealing effect is good.

[0041] The end cover 23 also comprises a hand-holding part connected with the cover body, which provides a convenient gripping point for the user of the first reagent tube 2, so that the user can easily open or close the end cover 23. The design of the hand-holding part can be selected in different shapes and sizes according to actual needs, for example, adding a ring-shaped protrusion or groove to facilitate the user to exert force with fingers or palms. As shown, the hand-holding part is arranged on the outer periphery of the cover body. This structure not only improves the convenience of operation of the end cover 23, but also reduces the damage of the cover body caused by excessive force during use, leading to leakage. Figure 2

[0042] The opening and closing operation of the end cover 23 needs to be realized by rotation, pressing or other appropriate ways. In one embodiment, the end cover 23 is of a screw type structure, which facilitates the user to completely tighten the end cover 23 by rotation, thereby ensuring the sealing. In another embodiment, a buckle type design is adopted, without rotation, the user only needs to press the end cover 23 slightly to fix it on the top port of the first reagent tube 2.

[0043] The first reagent tube 2 in the embodiment of the utility model also comprises a connecting piece 24, one end of the connecting piece 24 is connected with the end cover 23 (such as the outer periphery of the cover body), and the other end of the connecting piece 24 is connected with the top of the first reagent tube 2. The end cover 23 will not be separated from the first reagent tube 2 during use, thereby preventing the end cover 23 from being lost or missing, ensuring that the end cover 23 is always fixedly connected with the first reagent tube 2, facilitating the user to operate and improving the use efficiency. In one embodiment, the connecting piece 24 is an elastic connecting piece 24.

[0044] The serum placement device in the embodiment of the utility model can also be applicable to large-capacity detection. Specifically, the reagent box 1 also comprises a main body 11 and a second reagent tube 12, and the placement hole 16 is arranged on the top surface of the main body 11, and the second reagent tube 12 is clamped in the placement hole 16. The volume of the second reagent tube 12 is greater than that of the first reagent tube 2. The top surface of the second reagent tube 12 can be flush with the top surface of the main body 11, and the second reagent tube 12 can also be at least partially protruded on the top surface of the main body 11, as shown. Figure 4 Figure 1 The inner diameter size of the second reagent tube 12 matches the outer diameter size of the first reagent tube 2, and when small-capacity serum is detected, the first reagent tube 2 is clamped in the second reagent tube 12, as shown. In the case that the placement hole 16 is multiple, the second reagent tube 12 is also multiple, and adjacent two second reagent tubes 12 can be connected through a connecting rod to prevent the second reagent tube 12 from falling into the main body 11, as shown. Figure 1 Figure 4 ​​​As shown. Further, the first reagent tube 2 is connected to the second reagent tube 12 via a cable 3. Specifically, one end of the cable 3 is connected to the first reagent tube 2, and the other end of the cable 3 is connected to the second reagent tube 12, thereby fixing the first reagent tube 2 inside the second reagent tube 12. This prevents the first reagent tube 2 from falling out and also helps the user to remove the first reagent tube 2 via the cable 3.

[0045] Furthermore, the kit 1 also includes a sealing cap 13, and the second reagent tube 12 is at least partially protruding from the top surface of the main body 11. When the first reagent tube 2 is not present in the second reagent tube 12, or when the second reagent tube 12 is used for detection, the sealing cap 13 covers the second reagent tube 12. The sealing can be achieved by threaded connection or by plug-in connection.

[0046] The side wall of the main body 11 is also provided with a transparent portion 15, which corresponds to the second reagent tube 12 inserted into the main body 11. The user can observe the amount of serum sample in the second reagent tube 12 through the transparent portion 15, which helps to confirm the content of the drawn serum. In one embodiment, the side wall of the main body 11 is provided with an opening, which corresponds to the second reagent tube 12 inserted into the main body 11, so that the amount of serum sample in the second reagent tube 12 can be directly observed.

[0047] In this embodiment of the invention, the main body 11 is further provided with a mounting structure 14, through which the serum placement device can be mounted on the equipment. Figure 4 and Figure 5 As shown, the main body 11 has a notch, that is, the mounting structure 14 is a notch, and the serum device is secured to the device through the notch.

[0048] During use, if a small volume of serum needs to be tested, first remove the sealing cap 13 from the top of the second reagent tube 12, insert the first reagent tube 2 into the second reagent tube 12, and connect the first reagent tube 2 with a cable 3 wound and knotted, the other end of the cable 3 connected to the second reagent tube 12. Pour a certain amount (e.g., 2 ml) of serum into the first reagent tube 2. After use, open the end of the cable 3 connected to the second reagent tube 12, slowly lift the cable 3, and the first reagent tube 2 can be directly removed from the second reagent tube 12. After removal, disconnect the cable 3, and place the end cap 23 on the opening of the first reagent tube 2 to preserve the serum and prevent serum contamination. When a large volume of serum sample needs to be tested, the sealing cap 13 can be removed, and serum can be directly injected into the second reagent tube 12 for testing.

[0049] The serum placing device can be suitable for detection of serums with different capacities, the kit 1 can be repeatedly used, only the first reagent tube 2 needs to be replaced, the problem that if the serum amount is small in the prior art, the liquid level is very shallow when the serum is poured into the UDR kit, the probe responsible for sucking cannot suck the serum, the determination cannot be completed, and the remaining serum in the UDR kit 1 is directly discarded, the serum is wasted, or the serum of the same batch number is poured, and the serum is easily contaminated is solved.

[0050] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
