Description

Technical Field

[0001] The present application belongs to the field of medical detection technology, and specifically relates to a sample adding device and a detection system for a detection system. Background Art

[0002] In the medical diagnosis industry, adding samples is an essential operation before diagnosis. In the prior art, operators usually hold a quantitative dropper assembly (such as CN220027061U) to add samples to the reagent tube. However, since most quantitative dropper assemblies are small in length and diameter, when adding samples, the operator holds the quantitative dropper assembly and the reagent tube with both hands respectively, and then manually squeezes the quantitative dropper assembly to drop the sample into the reagent tube. After the addition is completed, the quantitative dropper assembly is put down and the sealing plug is picked up to seal the tube mouth of the reagent tube. The operation is cumbersome and time-consuming. In addition, during the above-mentioned addition process, the quantitative dropper assembly is mostly in an exposed air environment, resulting in the sample being exposed to the air for a long time, which may cause pollution to the environment. Impurities in the air (such as dust) may also enter the sample with the movement of the air, thereby causing inaccurate subsequent test results of the sample. Summary of the Invention

[0003] The purpose of the present application is to provide a sample adding device and a detection system for a detection system, which have the advantages of simple structure and can achieve pollution-free sample adding.

[0004] In order to achieve the above-mentioned object, the first aspect of the present application provides a sample adding device for a detection system, the detection system comprising a dropper, a reagent tube and a blocking member, the sample adding device comprising:

[0005] A receiving member, wherein a first receiving cavity and a second receiving cavity are formed inside the receiving member, both of which are vertically distributed. The first receiving cavity is used to install the dropper and has a limiting end surface formed inside for abutting the step surface of the dropper. The second receiving cavity is used to accommodate a vertically movable blocking member;

[0006] The reagent tube mounting piece is arranged at the bottom of the accommodating piece and has a mounting cavity communicated with the first accommodating cavity and the second accommodating cavity. The mounting cavity is used for the reagent tube to be inserted upward and moved.

[0007] In an embodiment of the present invention, an outlet for removing the reagent tube is formed at one end of the installation cavity close to the second accommodating cavity.

[0008] In an embodiment of the present invention, a first limiting protrusion assembly for limiting the position of the reagent tube is provided on the cavity wall of the installation cavity near one end of the outlet.

[0009] In an embodiment of the present invention, a first stop position and a second stop position are formed in the installation cavity, which are respectively located below the first accommodating cavity and the second accommodating cavity, and a second limiting protrusion assembly is provided on the cavity wall of the installation cavity, which is located between the first stop position and the second stop position.

[0010] In an embodiment of the present invention, a plurality of blocking member limiting protrusions distributed at intervals in the vertical direction and used to limit the blocking member are formed on the cavity wall of the second accommodating cavity.

[0011] In an embodiment of the present invention, a vertically distributed pressing member installation groove is formed on the cavity wall of the second accommodating cavity on the side away from the first accommodating cavity, and the sample loading device also includes a pressing member that is movably clamped in the pressing member installation groove and is used to press down the blocking member.

[0012] In an embodiment of the present invention, the pressing member includes a connecting portion, a pressing portion and a force-bearing portion, the connecting portion can be vertically movably arranged in the pressing member mounting groove, the pressing portion is arranged at the first end of the connecting portion and is located in the second accommodating cavity, and the force-bearing portion is arranged at the second end of the connecting portion and is located on the outside of the accommodating member.

[0013] In an embodiment of the present invention, anti-slip grooves are formed on the vertical side wall of the force-bearing portion on a side away from the accommodating member.

[0014] In an embodiment of the present invention, there are multiple first accommodating cavities, and the multiple first accommodating cavities are distributed in a transverse or annular manner.

[0015] A second aspect of the present application provides a detection system, which includes the above-mentioned sample adding device for the detection system.

[0016] It can be seen from the above technical solution that the sample adding device includes: a accommodating part, the interior of which is formed with a first accommodating cavity and a second accommodating cavity, both of which are vertically distributed. The first accommodating cavity is used to install a dropper and is formed with a limiting end surface for abutting the step surface of the dropper. The second accommodating cavity is used to accommodate a vertically movable blocking part; a reagent tube mounting part, which is arranged at the bottom of the accommodating part and has an mounting cavity connected to the first accommodating cavity and the second accommodating cavity. The mounting cavity is used for the reagent tube to be inserted upward and moved. The sample adding device has a simple structure. When the sample adding device is used to add samples to the reagent tube, the operator does not need to hold a dropper and a reagent tube to perform dripping and adding samples as in the prior art. Instead, the operator installs the dropper in the first accommodating chamber, and the reagent tube is inserted upward and installed in the installation chamber. The interior of the reagent tube and the portion below the limiting end surface of the first accommodating chamber form a closed space. The sample is kept in a closed environment during the process of flowing from the dropper into the reagent tube, which can prevent the sample from contacting the outside air and prevent impurities in the air from entering the sample during the adding process, thereby achieving pollution-free adding, which is conducive to improving the accuracy of subsequent sample testing. It also allows the adding process to be carried out in a non-biological safety cabinet, expanding the range of the adding environment. In addition, after the adding is completed, the operator moves the reagent tube so that it is located below the second accommodating chamber, and applies force to the sealing member in the second accommodating chamber to move it downward to seal the tube mouth of the reagent tube. There is no need to put down the quantitative dropper assembly and pick up the sealing plug to seal the tube mouth of the reagent tube after the adding is completed as in the prior art. The sample adding device of the present application simplifies the operator's adding operation process, which is conducive to shortening the adding time and improving the adding efficiency.

DETAILED DESCRIPTION

[0030] The following describes the specific embodiments of the present application in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not intended to limit the present application.

[0031] In the embodiment of the present application, a new type of sample adding device for a detection system is provided. The detection system includes a dropper 1 (such as Figure 7 As shown), reagent tube 2 (as Figure 8 As shown) and the blocking member 3 (as Figure 9 As shown), Figure 1-Figure 3 As shown, the sample adding device comprises:

[0032] The accommodating member 4 has a first accommodating cavity 401 and a second accommodating cavity 402 formed therein, both of which are vertically distributed. The first accommodating cavity 401 is used to install the dropper 1 and has a limiting end surface 403 formed therein for abutting the stepped surface of the dropper 1. The second accommodating cavity 402 is used to accommodate the vertically movable blocking member 3;

[0033] The reagent tube mounting member 5 is provided at the bottom of the accommodating member 4 and has an installation cavity 501 communicating with the first accommodating cavity 401 and the second accommodating cavity 402 . The installation cavity 501 is used for the reagent tube 2 to be inserted, installed and moved upward.

[0034] Specifically, the dropper 1 contains a sample to be dripped out, and the reagent tube 2 is used to contain the sample dripped out from the dropper 1. The reagent tube 2 includes a tube body and a dripping head. The dripping head includes a connecting portion 801 detachably connected to the tube body and a liquid outlet portion located below the connecting portion 801. The step surface in this embodiment is the lower end surface of the connecting portion 801. After the reagent tube 2 is installed in the first accommodating cavity 401, the lower end surface of the connecting portion 801 abuts against the limiting end surface 403 to limit the dropper 1 from moving further downward; the blocking member 3 can be a sealing plug or a reagent tube cover, etc., for blocking the reagent tube 2; when it is necessary to add a sample, the operator first inserts the dropper 1 from top to bottom into the first accommodating cavity 401 to Complete the installation of the dropper 1. After the installation of the dropper 1 is completed, the dripper of the dropper 1 is facing downward; the operator then places the blocking piece 3 in the second accommodating chamber 402 (the installation order of the dropper 1 and the blocking piece 3 can be interchanged); after the installation of the dropper 1 and the blocking piece 3 is completed, the operator opens the mouth of the reagent tube 2 and inserts the reagent tube 2 upward and installs it in the installation chamber 501. After the installation is completed, the reagent tube 2 is directly below the first accommodating chamber 401, and the top wall of the reagent tube 2 abuts against the top wall of the installation chamber 501, so that the interior of the reagent tube 2 can be connected to the liquid outlet of the dropper 1, and at this time, the interior of the reagent tube 2 and the part below the self-limiting end face 403 of the first accommodating chamber 401 form a closed space.

[0035] Furthermore, in this embodiment, an extrusion body is formed on the top of the tube body. When the extrusion body is pressed downward, the internal pressure of the dropper 1 increases, and the sample can flow out from the liquid outlet on the drip head. Therefore, after the dropper 1, the blocking member 3 and the reagent tube 2 are installed (as shown in FIG. Figure 5-Figure 6As shown in FIG, the operator squeezes the squeezing portion of the dropper 1 to make the sample in the dropper 1 flow out and enter the reagent tube 2. During the sample dripping process, since the interior of the reagent tube 2 and the portion below the limiting end surface 403 of the first accommodating cavity 401 form a closed space, the sample falls in the closed space and will not come into contact with the outside air. Impurities in the air will not enter the sample, thus achieving pollution-free sampling, which is beneficial to improving the accuracy of subsequent sample testing and also enables the sampling process to be carried out in a non-biological safety cabinet, expanding the range of the sampling environment. In this embodiment, the first accommodating cavity 401 and the second accommodating cavity 402 are distributed laterally at intervals. After the dripping is completed, a thrust is applied to the reagent tube 2, so that the reagent tube 2 moves horizontally from the bottom of the first accommodating chamber 401 to the bottom of the second accommodating chamber 402; after the reagent tube 2 moves horizontally into place, the operator applies downward pressure to the sealing member 3, so that it moves downward and seals at the tube mouth of the reagent tube 2. The operator does not need to put down the quantitative dropper assembly and pick up the sealing plug to seal the tube mouth of the reagent tube after the sample addition is completed as in the prior art, which simplifies the sample addition operation process, helps to shorten the sample addition time and improve the sample addition efficiency. Afterwards, the operator can remove the reagent tube 2 and the sealing member 3 as a whole from the sample addition device, and the sample addition of the reagent tube 2 is now completed.

[0036] Furthermore, the dropper 1 in this embodiment is a quantitative dropper. Using the quantitative dropper for quantitative addition can ensure the accuracy of the sample addition amount, which is conducive to further improving the accuracy of subsequent sample detection.

[0037] Furthermore, the container 4 and the reagent tube mounting member 5 in this embodiment are integrally injection-molded to form a carrier, which can further reduce the overall manufacturing difficulty of the container 4 and the reagent tube mounting member 5, and is conducive to improving the production efficiency of the sample loading device.

[0038] Furthermore, the sample loading device in this embodiment also includes a well plate, on which a reagent tube accommodating cavity is formed, which is concave from top to bottom and is used to accommodate some reagent tubes 2. Before loading, the operator can insert the reagent tube 2 and install it in the installation cavity 501, and then place the reagent tube 2 in the reagent tube accommodating cavity of the well plate. After squeezing the dropper 1, force is applied to the whole composed of the accommodating part 4 and the reagent tube mounting part 5, so that the whole composed of the well plate and the reagent tube 2 moves relative to the whole composed of the accommodating part 4 and the reagent tube mounting part 5, and the reagent tube 2 can be moved from the bottom of the first accommodating cavity 401 to the bottom of the second accommodating cavity 402 in the installation cavity 501. The above process does not require the operator to hold the reagent tube 2 and apply force to it, which improves the convenience of moving the reagent tube 2.

[0039] In one embodiment of the present invention, Figure 3As shown, the installation cavity 501 is formed with an outlet 502 for the removal of the reagent tube 2 at one end close to the second accommodating cavity 402, so that the reagent tube 2 and the sealing member 3 can be moved out of the combination of the accommodating member 4 and the reagent tube installation member 5 after completing the sealing cooperation, without the operator having to apply force to the combination of the accommodating member 4 and the reagent tube installation member 5 to pull it downward from the loading device, thereby improving the convenience of moving the combination of the reagent tube 2 and the sealing member 3 out of the combination of the accommodating member 4 and the reagent tube installation member 5, and helping to further improve the loading efficiency.

[0040] In one embodiment of the present invention, a first limiting protrusion assembly 6 for limiting the position of the reagent tube 2 is provided on the cavity wall of the installation cavity 501 near the outlet 502. Figure 3 As shown, the first limiting protrusion assembly 6 includes a first limiting protrusion 601 and a second limiting protrusion 602, both of which are vertically distributed. The first limiting protrusion 601 and the second limiting protrusion 602 are located on opposite sides of the cavity wall of the installation cavity 501 and are close to the outlet 502. When the reagent tube 2 moves from the bottom of the first accommodating cavity 401 to the bottom of the first accommodating cavity 401, the first limiting protrusion assembly 6 can effectively prevent the reagent tube 2 from accidentally falling off from the installation cavity 501.

[0041] Furthermore, the horizontal cross-sections of the first limiting ridge 601 and the second limiting ridge 602 are semicircular or U-shaped. The first limiting ridge 601 and the second limiting ridge 602 with the above cross-sectional shapes can better play a limiting role and have the advantages of simple structure and easy production and manufacturing.

[0042] Furthermore, the material of the first limiting protrusion component 6 includes bread glue or silicone, which has a low cost and is conducive to reducing the overall manufacturing cost of the sample adding device.

[0043] In one embodiment of the present invention, a first stop position 503 and a second stop position 504 are formed in the installation cavity 501, which are respectively located below the first accommodating cavity 401 and the second accommodating cavity 402, and a second limiting protrusion assembly 7 is provided on the cavity wall of the installation cavity 501, which is located between the first stop position 503 and the second stop position 504.

[0044] Specifically, when installing the reagent tube 2, the reagent tube 2 needs to be inserted upward into the first stop position 503 of the installation cavity 501; after the sample is dripped, the reagent tube 2 needs to be moved from the first stop position 503 to the second stop position 504 so that the sealing member 3 located above the second stop position 504 can seal the reagent tube 2. Figure 3As shown, the second limiting protrusion assembly 7 includes a third limiting protrusion 701 and a fourth limiting protrusion 702, both of which are vertically distributed. The third limiting protrusion 701 and the fourth limiting protrusion 702 are located on opposite sides of the cavity wall of the installation cavity 501, which can prevent the reagent tube 2 from moving from the first stop position 503 to the second stop position 504 due to accidental external force during the sample dripping process, and can also prevent the reagent tube 2 from moving from the second stop position 504 to the first stop position 503 due to accidental external force during the process of sealing the reagent tube 2, thereby improving the reliability of the sample adding device.

[0045] Similarly, further, the horizontal cross-sections of the third limiting ridge 701 and the fourth limiting ridge 702 are semicircular or U-shaped. The third limiting ridge 701 and the fourth limiting ridge 702 with the above cross-sectional shapes can better play a limiting role, and have the advantages of simple structure and easy production and manufacturing.

[0046] Similarly, further, the material of the second limiting protrusion component 7 includes bread glue or silicone, which has a low cost and is conducive to further reducing the overall manufacturing cost of the sample adding device.

[0047] In one embodiment of the present invention, Figure 1 As shown, a plurality of blocking member limiting protrusions 404 distributed at intervals in the vertical direction and used to limit the blocking member 3 are formed on the cavity wall of the second accommodating cavity 402 .

[0048] Specifically, the second accommodating cavity 402 can accommodate multiple vertically stacked sealing members 3, which can avoid the need to install the sealing members 3 in the second accommodating cavity 402 multiple times, and can improve the overall sampling efficiency during multiple sampling processes; further, a corresponding annular limiting portion is formed on the sealing member 3 to cooperate with the sealing member limiting protrusion 404. The setting of the sealing member limiting protrusion 404 can make the distance between the two adjacent sealing members 3 above and below appropriate, thereby avoiding the upper and lower sealing members 3 from being embedded together and sealing on one reagent tube 2 at the same time, further improving the ease of use of the sampling device.

[0049] In one embodiment of the present invention, a vertically distributed pressing member mounting groove 405 is formed on the cavity wall of the second accommodating cavity 402 on the side away from the first accommodating cavity 401, and the sample loading device also includes a pressing member 8 that is movably clamped in the pressing member mounting groove 405 and is used to press down the blocking member 3.

[0050] Specifically, the upper end of the pressure member installation groove 405 is open, and the lower end is connected to the outlet 502. This arrangement facilitates the installation or removal of the pressure member 8; the operator applies downward pressure on the blocking member 3 in the second accommodating cavity 402 through the pressure member 8, so that the blocking member 3 moves downward and blocks the reagent tube 2, thereby improving the convenience and efficiency of the blocking operation.

[0051] In one embodiment of the present invention, Figure 4 As shown, the pressing member 8 includes a connecting portion 801, a pressing portion 802 and a force-bearing portion 803. The connecting portion 801 can be vertically movably arranged in the pressing member mounting groove 405. The pressing portion 802 is arranged at the first end of the connecting portion 801 and is located in the second accommodating cavity 402. The force-bearing portion 803 is arranged at the second end of the connecting portion 801 and is located on the outside of the accommodating member 4.

[0052] Specifically, the operator applies a downward force to the force-bearing part 803, and the force-bearing part 803 then transmits the force in sequence to the connecting part 801 and the pressing part 802, and the pressing part 802 then transmits the force to the blocking part 3 to move the blocking part 3 downward. The pressing part 8 has a simple structure and a reasonable design, and it is also convenient for the operator to apply pressure to the blocking part 3; further, the pressing part 802 is cylindrical and the outer diameter of the pressing part 802 is consistent with the inner diameter of the second accommodating cavity 402. This arrangement makes the pressing part 8 easy to produce and manufacture, and also allows the pressing part 802 and the blocking part 3 to have a sufficient contact area, which is conducive to the pressing part 802 uniformly applying downward pressure to the blocking part 3; the force-bearing part 803 is flat and distributed vertically. The force-bearing part 803 is close to the vertical side wall of one side of the accommodating part 4 and is in contact with the outer wall of the accommodating part 4, which improves the structural compactness of the sample loading device and helps to reduce the space occupied by the sample loading device.

[0053] In one embodiment of the present invention, an anti-slip groove 804 is formed on the vertical side wall of the force-bearing portion 803 away from the receiving member 4 .

[0054] Specifically, the anti-slip pattern 804 in this embodiment is composed of a plurality of strip-shaped protrusions distributed at intervals along the vertical direction, and the strip-shaped protrusions are arranged along the horizontal direction. This form of anti-slip pattern 804 can not only increase the friction between the operator and the force-bearing part 803, and have a good anti-slip effect, but also improve the effectiveness of applying force to the downward pressing part 8, and also has the advantages of simple structure and easy processing and manufacturing.

[0055] In one embodiment of the present invention, there are multiple first accommodating cavities 401, and the multiple first accommodating cavities 401 are distributed at intervals in the transverse or circumferential direction. The arrangement of the multiple first accommodating cavities 401 enables the accommodating member 4 to simultaneously install multiple droppers 1, and the reagent tube 2 can move in the installation cavity 501 below each first accommodating cavity 401; further, according to actual use requirements, the multiple droppers 1 can accommodate the same type of samples or different types of samples, without the need to replace the dropper 1 multiple times, that is, multiple sample additions or continuous sample additions can be achieved in a short time, which can greatly improve the sample addition efficiency and help expand the scope of application of the sample addition device.

[0056] In this embodiment, multiple first accommodating cavities 401 are all located on the same side of the second accommodating cavity 402 and are distributed along the lateral intervals. When the operator needs to change the lateral position of the reagent tube 2 between two adjacent first accommodating cavities 401, or between the first accommodating cavity 401 and the second accommodating cavity 402, he only needs to apply a lateral thrust to the reagent tube 2 (or place the reagent tube 2 on the orifice plate and apply a lateral thrust to the sample loading device). That is, this layout of the sample loading device is conducive to reducing the difficulty of the operator's force application and is conducive to improving the user experience of the sample loading device.

[0057] In another embodiment, the plurality of first accommodating cavities 401 and the second accommodating cavities 402 are distributed in an annular shape. Furthermore, the overall structure formed by the accommodating member 4 and the reagent tube mounting member 5 is also annular. The lower pressure member mounting groove 405 is formed on the outer wall of the accommodating member 4, the outlet 502 is formed on the outer wall of the reagent tube mounting member 5, and the force-bearing portion 803 is located on the outer side of the accommodating member 4. This layout is conducive to reducing the lateral width of the sample loading device, making the overall layout of the sample loading device more compact. Furthermore, the overall structure formed by the plurality of first accommodating cavities 401 and the second accommodating cavities 402 in this embodiment can also be arranged in other forms according to actual needs, such as C-shaped or U-shaped.

[0058] The method of using the sample adding device in the embodiment of the present invention is as follows:

[0059] Before adding the sample, the operator first inserts the dropper 1 from top to bottom (with the dripper head facing downward) into the first accommodating cavity 401 of the accommodating member 4 to complete the installation of the dropper 1. After the dropper 1 is installed, the operator places the blocking member 3 in the second accommodating cavity 402, and then installs the pressing member 8 in the pressing member installation groove 405. Then, the operator opens the nozzle of the reagent tube 2 and inserts the reagent tube 2 upward and installs it in the installation cavity 501. After the reagent tube 2 is installed, it is directly below the first accommodating cavity 401.

[0060] After the dropper 1, the blocking piece 3, the reagent tube 2 and the pressing piece 8 are installed, the operator places the whole composed of the dropper 1, the blocking piece 3 and the reagent tube 2 on the orifice plate (the reagent tube 2 is in the reagent tube accommodating cavity of the orifice plate), and then squeezes the squeezing part of the dropper 1 downward to make the sample in the dropper 1 flow out and enter the reagent tube 2; after the sample is dripped in, force is applied to the whole composed of the accommodating piece 4 and the reagent tube mounting piece 5, so that the whole composed of the orifice plate and the reagent tube 2 moves relative to the whole composed of the accommodating piece 4 and the reagent tube mounting piece 5, so as to move the reagent tube 2 to the bottom of the second accommodating cavity 402, and the operator applies downward pressure on the blocking piece 3 in the second accommodating cavity 402 through the pressing piece 8, so that the blocking piece 3 moves downward and blocks the reagent tube 2;

[0061] After the reagent tube 2 is sealed, the operator applies force to the whole composed of the container 4 and the reagent tube installation part 5 again, so that the whole composed of the orifice plate and the reagent tube 2 moves relative to the whole composed of the container 4 and the reagent tube installation part 5, so as to separate the whole composed of the reagent tube 2 and the sealing part 3 that have completed the sealing and the combination of the container 4 and the reagent tube installation part 5. At this point, the sample addition operation is completed.

[0062] When using the above-mentioned sample adding device to add samples to the reagent tube 2, the operator does not need to hold the dropper 1 and the reagent tube 2, nor does he need to manually pick up the sealing member 3 and then seal it on the tube mouth of the reagent tube 2. The operation is simpler and takes less time, which greatly improves the simplicity and efficiency of sample adding. In addition, it can also prevent the sample from contacting the outside air and prevent impurities in the air from entering the sample during the sample adding process, thereby achieving pollution-free sample adding, which is beneficial to improving the accuracy of subsequent sample testing, and also enables the sample adding process to be carried out in a non-biological safety cabinet, expanding the range of the sample adding environment.
