Summary of the invention

[0003] The purpose of the present application is to provide a tube and a workstation, which simplifies the operation steps and improves the detection efficiency and accuracy.

[0004] In order to achieve the above-mentioned purpose, in the first aspect, an embodiment of the present application provides a tube, including a first tube body, a second tube body and a filter element, wherein the first tube body is provided with a mounting port; the first tube body is sleeved on the second tube body, and the second tube body is sealed and detachably connected to the mounting port of the first tube body, and the second tube body is provided with an inlet and an outlet, wherein the inlet is located at one end of the second tube body close to the mounting port, and the outlet is connected to the inside of the first tube body, and the second tube body is pre-filled with liquid, and the filter element is arranged near the outlet of the second tube body. After the inlet of the second tube body is sealed, the pre-filled liquid is stably maintained above the filter element. The supporting force of the filter element, the tension of the liquid, and the capillary force formed by the micro-channels inside the filter element form a resistance force that enables the liquid to overcome its own gravity and remain in the second tube body, thereby keeping the liquid in the second tube body; the filter element is arranged at the outlet of the second tube body.

[0005] In one embodiment, the inner diameter of the second tube gradually decreases along the Z-axis direction, and the Z-axis direction is parallel to the axis of the second tube and points from the inlet to the outlet.

[0006] In one embodiment, along the Z-axis direction, the outer diameter of the filter element gradually decreases or remains consistent.

[0007] In one embodiment, the filter pore diameter of the filter element is A, wherein 1 μm≤A≤20 μm.

[0008] In one embodiment, a limit ring is provided on the inner wall of the outlet of the second tube body, and the limit ring is used to limit the displacement of the filter element.

[0009] In one embodiment, the first tube body is detachably connected to the second tube body.

[0010] In one embodiment, a connecting sleeve is sleeved on the second tube body, and the first tube body and the second tube body are sealed and detachably connected via the connecting sleeve.

[0011] In one embodiment, the connecting sleeve is threadedly connected to the second pipe body and the first pipe body respectively.

[0012] In one embodiment, the connecting sleeve and the second tube body are an integrally formed structure; the connecting sleeve is threadedly connected to the first tube body.

[0013] In one embodiment, the tube further includes a connecting belt and a buckle cover, one end of the connecting belt is fixedly arranged; the buckle cover is connected to the other end of the connecting belt, and the buckle cover is installed at the inlet of the second tube body to close the inlet.

[0015] In one embodiment, the tube further comprises a heat-sealing film, and the heat-sealing film is disposed at the inlet, so that the inlet is sealed by the heat-sealing film to maintain sealing inside the first tube body and the second tube body.

[0018] The tube provided in the embodiment of the present application pre-loads liquid in the second tube body. The supporting force of the filter element, the tension of the liquid, and the capillary force formed by the tiny channels inside the filter element enable the pre-loaded liquid to overcome its own gravity and remain in the second tube body, thereby eliminating the step of adding liquid to the second tube body. The flocked swab is placed in the second tube body without taking it out, thereby reducing the manual operation of manually squeezing the swab head and pinching the tube to drip samples during testing, thereby improving the testing efficiency.

[0034] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0035] In the description of this application, it should be noted that the terms "inside", "outside", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the application is usually placed when in use, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0036] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0037] In a first aspect, an embodiment of the present application provides a tube, such as Figure 6 and Figure 7 As shown, the tube includes a first tube body 100 , a second tube body 200 and a filter element 300 .

[0038] like Figure 2As shown, a mounting opening 110 is provided on the first tube body 100 .

[0039] like Figure 2 and Figure 7 As shown, the first tube body 100 is sleeved on the second tube body 200 , and the second tube body 200 is sealed and detachably connected to the installation port 110 of the first tube body 100 . The second tube body 200 blocks the installation port 110 to prevent fluid from passing through the installation port 110 .

[0040] like Figure 4 and Figure 5 As shown, the second tube body 200 is provided with an inlet 210 and an outlet 220; Figure 7 As shown, the inlet 210 is located at one end of the second tube body 200 near the mounting port 110, and the outlet 220 is connected to the interior of the first tube body 100. During use, after collecting oropharyngeal, nasal and nasopharyngeal samples with a flocked swab, the flocked swab is inserted into the second tube body 200 from the inlet 210, so that the sample enters the second tube body 200.

[0041] The second tube body 200 is pre-filled with liquid, which is a sample preservation liquid. The support force of the filter element 300, the tension of the liquid, and the capillary force formed by the micro-channels inside the filter element 300 form a resistance force that enables the liquid to overcome its own gravity and thus remain in the second tube body 200. Therefore, regardless of whether the tube is placed vertically or horizontally, the sample preservation liquid stays in the second tube body 200 under the action of the above-mentioned combined force, unless the tube provided in the embodiment of the present application is pressurized, such as placed in a centrifuge for centrifugation or manually swung for centrifugation, the sample preservation liquid in the second tube body 200 can overcome the resistance and enter the first tube body 100.

[0042] In the present application, the thickness of the filter element 300, the volume of the pre-filled liquid, the difference in polarity between the filter element 300 material and the pre-filled liquid, and the pore size of the filter element 300 ensure that the filter element 300 supports the pre-filled liquid. The supporting force can overcome the liquid's own gravity, thereby keeping the liquid in the second tube body.

[0043] During use, the sample on the flocked swab is inserted into the second tube body 200 from the inlet 210, and the sample preservation solution in the second tube body 200 can dissolve the sample on the flocked swab, and the flocked swab is retained in the second tube body 200. The tube provided in the embodiment of the present application is placed in a centrifuge for centrifugation, so that the sample preservation solution in the second tube body 200 enters the first tube body 100. Then the second tube body 200 is taken out of the first tube body 100, and the second tube body 200 and the flocked swab are separated from the first tube body 100, and then the sample in the first tube body 100 is tested on the machine.

[0044] Exemplarily, other items may be used to collect samples, such as tweezers, wipes, etc. Samples may also be collected from sites other than the oropharynx, nose, and nasopharynx, such as the anus, eyeball, epidermis, etc.

[0045] The filter element 300 is disposed at the outlet 220 of the second tube body 200. When the sample preservation liquid in the second tube body 200 enters the first tube body 100, the filter element 300 can filter impurities in the sample preservation liquid, such as hair dropped by a swab, food residues, mucus, etc. The provided filter element 300 reduces impurities and improves the detection accuracy. Exemplarily, in one embodiment, the filter element 300 is made of a hydrophobic material, so that the filter element 300 can prevent the sample preservation liquid in the second tube body 200 from entering the first tube body 100, and even if the filter element 300 is made of a hydrophilic material, due to the surface tension of different preservation liquids, the capillary forces of different sizes formed by the filter elements 300 with different pore sizes (the smaller the pore size, the greater the capillary force), etc., the filter element 300 can also prevent the sample preservation liquid in the second tube body 200 from entering the first tube body 100 to a certain extent. In actual applications, a very small amount of sample preservation liquid may enter the first tube body 100, but it will not affect the actual detection.

[0046] The present application pre-loads liquid in the second tube body 200, and the supporting force of the filter element 300, the tension of the liquid, and the capillary force formed by the tiny channels inside the filter element 300 form a combined resistance force that enables the liquid to overcome its own gravity and remain in the second tube body 200, thereby keeping the liquid in the second tube body 200, eliminating the step of adding liquid to the second tube body 200, and the flocked swab does not need to be taken out after being placed in the second tube body 200, thereby reducing the manual operation of manually squeezing the swab head and pinching the tube to drop the sample during the test, thereby improving the test efficiency, and the filter element 300 is provided to reduce the interference of swabs and other debris on the test results, thereby improving the test accuracy, and the used flocked swabs can be retained in the second tube body 200, which can reduce the risk of contamination of the flocked swab samples.

[0047] like Figure 4 As shown, in one embodiment, the inner diameter of the second tube body 200 gradually decreases along the Z-axis direction, so that the inner wall at the outlet 220 of the second tube body 200 limits the displacement of the filter element 300, prevents the filter element 300 from falling into the first tube body 100, and can hinder the sample preservation liquid from flowing into the first tube body 100 to a certain extent through the gradually decreasing inner diameter of the second tube body 200.

[0048] The Z-axis direction is parallel to the axis of the second tube 200 and points from the inlet 210 to the outlet 220 .

[0049] The stable installation of the filter element 300 is crucial for the accuracy of sample filtration and detection. The design ensures the stability of the filter element 300 through physical constraints, avoiding the filter element 300 from falling off and affecting the filtration, resulting in a decrease in detection accuracy.

[0050] In one embodiment, the outer diameter of the filter element 300 is kept consistent in the Z-axis direction, so that the filter element 300 is closely matched with the inner wall of the outlet 220 on the second tube body 200, further preventing the filter element 300 from falling into the first tube body 100, and effectively preventing the filter element 300 from falling off due to vibration or external force during operation. This close fit provides additional physical constraints to ensure the stability and reliability of the filter element 300.

[0051] In another embodiment, the outer diameter of the filter element 300 gradually decreases along the Z-axis direction, so that the filter element 300 better fits the inner wall of the outlet 220, and reduces the deformation of the filter element 300 caused by extrusion or stretching during installation and use. The reduction of deformation helps to extend the service life of the filter element 300. By reducing deformation, it can be ensured that the filter element 300 can still maintain its designed filtering effect during long-term use.

[0052] By optimizing the matching relationship between the filter element 300 and the second tube body 200, this design helps to enhance the integrity of the overall structure, which not only improves the stability and durability of the device, but also ensures the safety and accuracy of the sample during processing.

[0053] In one embodiment, the filter pore diameter of the filter element 300 is A, wherein 1 μm ≤ A ≤ 20 μm. Exemplarily, the filter pore diameter A of the filter element 300 is 1 μm. In another embodiment, the filter pore diameter A of the filter element 300 is 3 μm. In another embodiment, the filter pore diameter A of the filter element 300 is 5 μm. In another embodiment, the filter pore diameter A of the filter element 300 is 8 μm. In another embodiment, the filter pore diameter A of the filter element 300 is 10 μm. In another embodiment, the filter pore diameter A of the filter element 300 is 15 μm. In another embodiment, the filter pore diameter A of the filter element 300 is 20 μm.

[0054] like Figure 4 As shown, in one embodiment, a connecting sleeve 240 is provided on the second tube body 200 , and the first tube body 100 and the second tube body 200 are sealed and detachably connected via the connecting sleeve 240 .

[0055] In one embodiment, the connecting sleeve 240 is threadedly connected to the second tube body 200 and the first tube body 100 respectively.

[0056] However, in another embodiment, the connecting sleeve 240 and the second tube body 200 are integrally formed, and the connecting sleeve 240 is threadedly connected to the first tube body 100. Figure 7 As shown, the connecting sleeve 240 is installed at the installation opening 110 of the first tube body 100 , so that the second tube body 200 is detachably connected to the first tube body 100 through the connecting sleeve 240 .

[0057] like Figure 7 As shown, illustratively, an internal thread is provided on the inner wall of the connecting sleeve 240, such as Figure 2 As shown, an external thread is provided on the outer wall of the installation opening 110 of the first tube body 100 , and the internal thread on the connecting sleeve 240 is threadably matched with the external thread on the outer wall of the installation opening 110 .

[0058] Exemplarily, anti-slip protrusions are provided on the outer wall of the connecting sleeve 240 .

[0059] like Figure 7 and Figure 8 As shown, in one embodiment, a limiting ring 230 is provided on the inner wall of the outlet 220 of the second tube body 200 , and the limiting ring 230 is used to limit the displacement of the filter element 300 .

[0060] Exemplarily, the limiting ring 230 includes a first ring body and a second ring body, which are sequentially arranged on the inner wall of the outlet 220 along the Z-axis direction, and the first ring body and the second ring body are arranged at intervals, and the filter element 300 is arranged at the interval between the first ring body and the second ring body. The displacement of the filter element 300 in the reverse direction of the axis is limited by the first ring body, the displacement of the filter element 300 in the axial direction is limited by the second ring body, and the displacement of the filter element 300 in the radial direction is limited by the inner wall of the outlet 220, so as to prevent the filter element 300 from unnecessary displacement in these directions, which helps to improve the stability of the filter element 300 during operation and ensure that it can continuously and effectively perform filtering operations.

[0061] The limiting ring 230 can also prevent the filter element 300 from falling off, because the filter element 300 is firmly restricted in the interval between the first ring body and the second ring body, and is unlikely to fall off from the outlet 220 even if it is subjected to external vibration or impact force. This increases the safety and reliability of the mechanical structure.

[0062] Exemplarily, the first ring body and the second ring body are fixedly arranged on the inner wall of the outlet 220 by welding, gluing, clamping or integral molding.

[0063] In one embodiment, the first tube body 100 and the second tube body 200 are detachably connected. It is convenient to remove the second tube body 200 from the first tube body 100 to improve the detection efficiency. Exemplarily, the first tube body 100 and the second tube body 200 are detachably connected by threaded connection, clamping, etc. In another embodiment, the second tube body 200 is inserted into the first tube body 100, and the first tube body 100 and the second tube body 200 adopt a transition fit.

[0064] After the tube provided in the embodiment of the present application is centrifuged, the first tube body 100 and the second tube body 200 are detachably connected, and the second tube body 200 can be quickly removed from the first tube body 100 to facilitate rapid testing of the first tube body 100 on a machine, thereby improving the testing efficiency, especially in large-scale testing.

[0065] like Fig. 9 As shown, in one embodiment, the tube provided in the embodiment of the present application further includes a connecting band 260 and a buckle cover 270 .

[0066] like Fig. 9 As shown, one end of the connecting belt 260 is fixedly arranged. For example, one end of the connecting belt 260 is fixedly arranged on the second tube body 200. For example, the connecting belt 260 and the second tube body 200 are fixedly connected by welding, gluing, clamping or integral molding. Alternatively, one end of the connecting belt 260 is fixedly arranged on the connecting sleeve 240 of the first tube body 100.

[0067] The buckle cover 270 is connected to the other end of the connecting belt 260. Exemplarily, the connecting belt 260 and the buckle cover 270 are fixedly connected by welding, gluing, snapping or integral molding.

[0068] For example, the connecting band 260 is deformable. The buckle cover 270 is installed at the inlet 210 of the second tube body 200 to close the inlet 210. Figure 7 As shown, at this time, the buckle cover 270 has been removed from the entrance 210, and the entrance 210 is in an open state.

[0069] Through the design of the connecting belt 260 and the buckle cover 270, the user can conveniently close and open the inlet 210. The buckle cover 270 can be tightly installed at the inlet 210 to ensure the sealing and safety of the sample. At the same time, when it is necessary to take or place the sample, the user can easily open the buckle cover 270, which is simple and quick to operate.

[0070] The technical solution of the connecting belt 260 and the buckle cover 270 in the above embodiment can also be replaced by the following technical solution: Figure 3 As shown, in one embodiment, the tube provided in the embodiment of the present application further includes a cover 250. Figure 1 and Figure 7 As shown, the cover 250 is detachably mounted at the inlet 210 of the second tube body 200 to close the sample inlet 210. Exemplarily, the cover 250 is threadedly connected or snap-connected with the second tube body 200. The following takes the threaded connection between the cover 250 and the second tube body 200 as an example to explain the technical solution of the present application.

[0071] Exemplarily, an inner wall of the cover 250 is provided with an internal thread, and an external thread matching the internal thread of the cover 250 is provided at the inlet 210 of the second tube body 200 , so that the cover 250 is threadedly connected to the second tube body 200 .

[0072] The cover 250 is connected to the inlet 210 of the second tube 200 by threads, which can ensure the tightness of the inlet 210 in a closed state. The threaded connection can provide a stable connection force, effectively preventing the sample preservation solution from leaking during storage or transportation, thereby ensuring the integrity and safety of the sample.

[0073] The threaded connection design makes the opening and closing operation of the cover 250 relatively simple. The user can connect or separate the cover 250 with the second tube body 200 by simply rotating the cover 250, without the need for additional tools or complicated operation steps. This design improves the convenience of use of the tube and reduces the difficulty of operation.

[0074] For example, Figure 3 As shown, anti-skid protrusions are provided on the outer wall of the cover 250. The anti-skid protrusions provided on the outer wall of the cover 250 increase the grip stability of the user when operating the cover 250. This design helps to prevent operational errors caused by hand slippage when rotating the cover 250, thereby improving the safety and accuracy of the operation. The threaded connection structure is relatively stable and can withstand certain external forces. At the same time, the threaded fit between the cover 250 and the second tube body 200 can ensure that it is not easy to loosen or be damaged during long-term use, thereby extending the service life of the tube provided in the embodiment of the present application.

[0075] In one embodiment, the tube provided in the embodiment of the present application also includes a heat-sealing film, which is arranged at the inlet 210 to seal the inlet 210 through the heat-sealing film to fully maintain the sealing properties, thereby preventing the sample preservative liquid from entering the first tube body 100 before centrifugation. If the sample preservative liquid enters the first tube body 100 before centrifugation, the sample preservative liquid in the second tube body 200 will be reduced, and the sample on the flocked swab will not be completely dissolved, thereby affecting the detection accuracy.

[0076] The heat-sealing film not only seals the sample, but also effectively prevents foreign matter from entering the first tube body 100 and the second tube body 200 from the inlet 210. This helps reduce the risk of sample contamination and improves the quality of sample preservation.

[0077] The heat-sealing film generally has a high sealing performance, and can ensure complete sealing of the inlet 210. This sealing performance is of great significance for preventing problems such as evaporation of the sample preservation solution and gas leakage, and can extend the storage time of the sample preservation solution.

[0078] Before the flocked swab is inserted into the second tube 200 , the heat-sealing film can be directly torn off.

[0079] In a second aspect, an embodiment of the present application further provides a workstation, which is a space or tool designed to support a specific type of work. The workstation includes a centrifugal device, a detection device, and a tube as described in any of the above embodiments.

[0080] The centrifugal device is used to centrifuge the tube, and the centrifugal device is, for example, a centrifuge.

[0081] The detection device is used to detect biological parameters of the sample in the tube body. The detection device is, for example, an electrophoresis instrument for separating and analyzing biological macromolecules (such as DNA, RNA and protein, etc.), a mass spectrometer for analyzing organic compounds (such as protein, nucleic acid, etc.) in biological specimens, or a chemiluminescence immunoassay analyzer that can at least be used to detect blood or its extracts.

[0082] Exemplarily, the first tube body is configured to be cylindrical, and a sample rack for mounting the first tube body is provided on the centrifugal device and the detection device. The first tube body is configured to be cylindrical to match the sample rack on the centrifugal device and the detection device, thereby improving versatility.

[0083] In one embodiment, the workstation further comprises a processing device and a waste storage device, wherein the waste storage device is used to store waste.

[0084] The processing device includes a moving unit and a separation unit. The moving unit is used to move the first tube body 100 from the centrifugal device to the detection device; the separation unit is used to separate the second tube body 200 of the tube from the first tube body 100 of the tube and put the second tube body into a waste storage device.

[0085] During use, the tube provided by the embodiment of the present application is first installed on a centrifugal device for centrifugation. After centrifugation, the tube is moved from the centrifugal device to the detection device by the moving unit, and then the second tube body 200 is removed from the first tube body 100, and the second tube body 200 is placed in a waste storage device. Then the detection device detects the biological parameters of the sample in the first tube body 100, such as DNA, RNA, and protein types. It should be understood that the steps of removing the second tube body 200 from the first tube body 100 and placing it in the waste storage device by the separation unit can also be performed simultaneously with "moving the tube from the centrifugal device to the detection device by the moving unit", that is, when the moving unit moves the first tube body 100 (the second tube body 200 is located on the first tube body 100) from the centrifugal device to the detection device, the separation unit simultaneously removes the second tube body 200 from the first tube body 100 and places the second tube body 200 in the waste storage device.

[0086] The moving unit and the separation unit are, for example, two robotic arms, one of which is used to move the first tube 100 from the centrifugal device to the detection device, and the other robotic arm is used to remove the second tube 200 from the first tube 100, and the removal action is, for example, rotating the second tube 200 to disengage the second tube 200 and the connecting sleeve 240 from the first tube 100. In another embodiment, the moving unit is, for example, a conveyor belt and a robotic arm, and the robotic arm removes the tube from the centrifugal device and places it on the conveyor belt, and the conveyor belt conveys the tube to the detection device, and then another robotic arm places the tube on the detection device.

[0087] It should be noted that, in the absence of conflict, the features in the embodiments of this application may be combined with each other.

[0088] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
