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 CN220027059U) to add samples to a 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 of samples is completed, the operator puts down the quantitative dropper assembly and picks up the sealing plug to seal the tube mouth of the reagent tube. The operation is cumbersome and time-consuming, resulting in low efficiency of adding samples, which in turn reduces the efficiency of sample detection. Utility Model Content

[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 are conducive to improving the sample adding efficiency and sample detection efficiency.

DETAILED DESCRIPTION

[0032] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0033] In the embodiment of the present application, a new type of sample adding device for a detection system is provided, such as Figure 1 As shown, the detection system includes a dropper 1 (such as Figure 8 As shown), reagent tube 2 (as Fig. 9 As shown) and the blocking member 3 (as Fig.10 As shown), the sample adding device comprises:

[0034] The container 4 has a first accommodating cavity 401 and a second accommodating cavity 402 therein. The first accommodating cavity 401 is used to install the dropper 1. The second accommodating cavity 402 is arranged at one side of the first accommodating cavity 401 and is used to accommodate the vertically movable blocking member 3.

[0035] The reagent tube mounting member 5 is detachably connected to the reagent tube 2 and forms a mounting cavity 501 . The mounting cavity 501 is located below the first accommodating cavity 401 and the second accommodating cavity 402 and communicates with the first accommodating cavity 401 and the second accommodating cavity 402 .

[0036] 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, and the dripping head includes a connecting section detachably connected to the tube body and a liquid outlet section located below the connecting section; the blocking member 3 can be selected as a sealing plug or a reagent tube cover, etc., which is used to block the reagent tube 2; when it is necessary to add samples, 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 dripping head of the dropper 1 faces downward; the operator then places the blocking member 3 in the second accommodating cavity 402 (the installation order of the dropper 1 and the blocking member 3 can be exchanged); after the installation of the dropper 1 and the blocking member 3 is completed, the operator opens the pipe mouth of the reagent tube 2 and installs the reagent tube 2 in the installation cavity 501. After the installation of the reagent tube 2 is completed, it is located directly below the first accommodating cavity 401, and the interior of the reagent tube 2 can be connected to the liquid outlet on the liquid outlet section.

[0037] 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. Figure 6-Figure 7 As shown in the figure, the operator squeezes the extrusion body of the dropper 1 to make the sample in the dropper 1 flow out and enter the reagent tube 2; in the present embodiment, the first accommodating chamber 401 and the second accommodating chamber 402 are distributed in a lateral interval, and after the sample is dripped, a thrust is applied to the reagent tube 2, so that the reagent tube 2 moves laterally from the bottom of the first accommodating chamber 401 to the bottom of the second accommodating chamber 402; after the reagent tube 2 is laterally moved into place, the operator applies downward pressure to the blocking member 3 to make it move downward and block 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 block the tube mouth of the reagent tube 2 after the sample addition is completed as in the prior art, which simplifies the sample addition operation process, is conducive to shortening the sample addition time and improving the sample addition efficiency, and then the operator removes the reagent tube 2 and the blocking member 3 as a whole from the sample addition device, and the sample addition of the reagent tube 2 is completed.

[0038] In one embodiment of the utility model, the installation cavity 501 is formed by being recessed upward from the bottom surface of the reagent tube mounting member 5. The installation cavity 501 with this structural form is convenient for the operator to open the pipe mouth of the reagent tube 2, insert the reagent tube 2 upward and install it in the installation cavity 501, so that the operator can quickly and conveniently install the reagent tube 2; the spacing between the two vertical side walls of the installation cavity 501 in the longitudinal direction is consistent with the maximum outer diameter of the reagent tube 2. This structural design enables the reagent tube 2 to be tightly connected to the sample adding device after installation, thereby improving the reliability of the sample adding device.

[0039] In one embodiment of the utility model, a mounting positioning portion 505 is also formed on the reagent tube mounting member 5, and the mounting positioning portion 505 is located on a side of the mounting cavity 501 close to the first accommodating cavity 401. Specifically, a positioning surface 5051 is formed on the mounting positioning portion 505, which can fit with a portion of the outer circumference of the reagent tube 2. The arrangement of the mounting positioning portion 505 and the positioning surface 5051 enables the operator to quickly install the reagent tube 2 below the first accommodating cavity 401 when installing it, which is beneficial to improving the installation accuracy of the reagent tube 2 and avoiding the operator from moving the reagent tube 2 horizontally multiple times to align the reagent tube 2 and the first accommodating cavity 401 up and down.

[0040] In another embodiment of the present invention, an inlet 506 for allowing the reagent tube 2 to enter the installation cavity 501 is formed on a vertical side wall at one lateral end of the installation cavity 501. Figure 4-Figure 5 As shown, in this embodiment, the first accommodating cavity 401 and the second accommodating cavity 402 are arranged at intervals in the transverse direction, and the installation cavity 501 is arranged in the transverse direction below the first accommodating cavity 401 and the second accommodating cavity 402. The bottom of the reagent tube installation member 5 is formed with a limiting portion 508 for clamping the limiting ring 201 of the reagent tube 2 and limiting the upward and downward movement of the reagent tube 2. The limiting portion 508 is formed with a strip groove 5081 distributed in the transverse direction, and the inlet 506 is located at a transverse end of the strip groove 5081. When installing the reagent tube 2, the operator pushes the reagent tube 2 in the transverse direction from the inlet 506 and clamps it in the strip groove 5081; after the reagent tube 2 is installed, part of the reagent tube 2 protrudes downward from the limiting portion 508, and the operator applies force to the part of the reagent tube 2 protruding downward from the limiting portion 508, so as to change the transverse position of the reagent tube 2, so as to facilitate the movement of the reagent tube 2 between the inlet 506, the bottom of the first accommodating cavity 401 and the bottom of the second accommodating cavity 402.

[0041] Furthermore, the inlet 506 is located at one lateral end of the installation cavity 501 close to the first accommodating cavity 401. This structural design allows the reagent tube 2 to be quickly moved to the bottom of the first accommodating cavity 401 after being installed in the installation cavity 501 and to accommodate the sample dripped out of the dropper 1, which is beneficial to simplify the sample addition steps and increase the sample addition speed.

[0042] In one embodiment of the utility model, the installation cavity 501 is formed with arc-shaped guide side walls 507 on both longitudinal sides of the inlet 506. Specifically, in the direction gradually approaching directly below the first accommodating cavity 401, the width between the vertical side walls on both longitudinal sides of the inlet 506 gradually decreases and forms guide side walls 507. The above arrangement reduces the difficulty of the reagent tube 2 entering the installation cavity 501 from the inlet 506, and further improves the convenience of installing the reagent tube 2.

[0043] In one embodiment of the utility model, the installation cavity 501 is formed with an outlet 502 for removing 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 the sealing cooperation is completed, without the need for the operator to apply force to the combination of the accommodating member 4 and the reagent tube installation member 5 to pull it downward from the sample loading device (or move the reagent tube 2 laterally to remove it from the inlet 506), thereby reducing the difficulty and time required to remove the combination of the reagent tube 2 and the sealing member 3 from the combination of the accommodating member 4 and the reagent tube installation member 5, which is conducive to further improving the sample loading efficiency.

[0044] 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 which are both 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.

[0045] 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 play a good limiting role and have the advantages of simple structure and easy production.

[0046] Furthermore, the material of the first limiting protrusion component 6 includes bread glue or silicone, and the cost of the above materials is relatively low, which is beneficial to reducing the overall manufacturing cost of the sample adding device.

[0047] In one embodiment of the utility model, a first stop position 503 and a second stop position 504 are formed in the installation cavity 501 and are located respectively 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 and is located between the first stop position 503 and the second stop position 504.

[0048] Specifically, when installing the reagent tube 2, the reagent tube 2 needs to be inserted upward to the position of 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 blocking member 3 located above the second stop position 504 can block 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 which are both 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.

[0049] 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.

[0050] Similarly, further, the material of the second limiting protrusion component 7 includes bread glue or silicone, and the cost of the above materials is relatively low, which is conducive to further reducing the overall manufacturing cost of the sample adding device.

[0051] In one embodiment of the present invention, a limiting end surface 403 for abutting against the step surface of the dropper 1 is formed inside the first accommodating cavity 401 .

[0052] Specifically, the step surface in this embodiment is the lower end surface of the connecting section. After the dropper 1 is installed in the first accommodating cavity 401, the lower end surface of the connecting section abuts against the limiting end surface 403 to limit the dropper 1 from moving further downward. After the operator opens the mouth of the reagent tube 2 and installs the reagent tube 2 in the installation cavity 501, 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. In the process of sample dripping, 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, achieving pollution-free sample addition, which is conducive to improving the accuracy of subsequent sample detection, and also enables the sample addition process to be carried out in a non-biological safety cabinet, expanding the range of the sample addition environment.

[0053] Furthermore, the dropper 1 in this embodiment is a quantitative dropper. The use of a 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.

[0054] 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, which is beneficial to improving the production efficiency of the sample adding device.

[0055] Furthermore, the loading device in this embodiment also includes a well plate, on which a reagent tube accommodating cavity is formed, which is recessed from top to bottom and is used to accommodate some reagent tubes 2. Before loading, the operator can insert the reagent tube 2 into the reagent tube accommodating cavity of the well plate after installing it in the installation cavity 501, and after squeezing the dropper 1, apply force to the whole composed of the accommodating member 4 and the reagent tube mounting member 5, so that the whole composed of the well plate and the reagent tube 2 moves relative to the whole composed of the accommodating member 4 and the reagent tube mounting member 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, thereby improving the convenience of moving the reagent tube 2.

[0056] In one embodiment of the present invention, Figure 1 As shown, a plurality of blocking member limiting protrusions 404 which are distributed at intervals in the vertical direction and are used to limit the blocking member 3 are formed on the cavity wall of the second accommodating cavity 402 .

[0057] Specifically, the second accommodating chamber 402 can accommodate multiple vertically stacked blocking members 3, which can avoid installing the blocking members 3 in the second accommodating chamber 402 multiple times, and can improve the overall sampling efficiency during multiple sampling processes; further, a corresponding annular limiting portion is formed on the blocking member 3 to cooperate with the blocking member limiting protrusion 404. The setting of the blocking member limiting protrusion 404 can make the distance between two adjacent blocking members 3 above and below appropriate, avoiding the upper and lower blocking members 3 from being embedded together and sealing on one reagent tube 2 at the same time, and further improving the convenience of using the sampling device.

[0058] In one embodiment of the utility model, a vertically distributed pressing member installation 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 movably mounted in the pressing member installation groove 405 and used to press down the blocking member 3.

[0059] 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 to the blocking member 3 in the second accommodating cavity 402 through the pressure member 8 to move the blocking member 3 downward and seal the reagent tube 2, thereby improving the convenience and efficiency of the sealing operation.

[0060] In one embodiment of the present invention, Fig.11As shown, the pressing member 8 includes a connecting portion 801, a pressing portion 802 and a force-bearing portion 803, the connecting portion 801 is 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, and 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.

[0061] Specifically, the operator applies a downward force to the force-bearing part 803, and the force-bearing part 803 then transmits the force to the connecting part 801 and the pressing part 802 in sequence, 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 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 chamber 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 beneficial for the pressing part 802 to uniformly apply downward pressure to the blocking part 3; the force-bearing part 803 is flat and distributed vertically, and the force-bearing part 803 is close to the vertical side wall of one side of the accommodating part 4 and fits together with the outer side 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.

[0062] In one embodiment of the present invention, an anti-slip pattern 804 is formed on the vertical side wall of the force-bearing portion 803 away from the receiving member 4 .

[0063] 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, thereby achieving a good anti-slip effect and improving the effectiveness of applying force to the downward pressing part 8, but also has the advantages of simple structure and easy processing and manufacturing.
