Description

Technical Field

[0001] This application relates to the field of environmental virus sampling devices, and more specifically, to a field space pathogen sampling kit for public safety. Background Technology

[0002] Sampling swabs and sample preservation tubing are widely used devices for collecting viral nucleic acid samples from the environment. Environmental virus sampling kits include viral sampling swabs and viral sample preservation tubing. These products are primarily suitable for routine sampling and testing of infectious pathogens, influenza virus, mycoplasma, chlamydia, ureaplasma, rubella, and measles virus from clinical patients by disease control departments and clinical settings. This facilitates subsequent nucleic acid extraction and molecular biological diagnostics using isolated viral materials.

[0003] However, existing collection devices have certain problems in actual nucleic acid collection operations: on the one hand, a complete pharyngeal swab is relatively long, and after the sample is collected, the swab head needs to be broken off and dropped into the collection tube, which is inconvenient for subsequent liquid retrieval operations; on the other hand, micro-leakage in existing preservation liquid tubes is not easily detected, thus posing a safety hazard to collection personnel and causing environmental pollution; finally, existing preservation liquid tubes do not provide sufficient vortex lysis, increasing the difficulty of subsequent re-collection and also increasing the cost of repeated nucleic acid collection. Utility Model Content

[0004] The purpose of this invention is to provide an environmental virus sampling kit to solve the problems of existing sampling devices, such as operational difficulties, interference from the swab head during sampling, leakage (micro-leakage after sampling cannot be detected in time, increasing the risk of biohazard), and low vortex mixing efficiency (existing manual vortexing after sampling is insufficient for complete fragmentation, resulting in insufficient detection sensitivity, increasing the difficulty of subsequent re-sampling, and also increasing the cost of nucleic acid collection).

[0005] This application provides a field space pathogenic microorganism sampling kit for public safety, comprising:

[0006] Preservative tube;

[0007] Sampling swabs;

[0008] A cap is provided at the open end of the preservation fluid tube to seal the preservation fluid tube;

[0009] An outer rotating sleeve is fitted over the preservation fluid tube, and the preservation fluid tube rotates relative to the outer rotating sleeve; and

[0010] A leak detection structure is installed at the connection between the pipe cap and the storage liquid tube. When the liquid in the storage liquid tube leaks, the leak detection structure changes color after contacting the liquid.

[0011] Furthermore, the preservation fluid tube includes:

[0012] Save the tube body;

[0013] Limiting ring one and limiting ring two are disposed on the storage tube body and are used to limit the outer rotating sleeve;

[0014] A gear structure is provided on the storage tube body, meshes with an external device, and is driven by the external device to rotate the storage tube body;

[0015] External threads are provided at the open end of the storage tube; and

[0016] A flange is provided on the storage tube body between the second limiting ring and the external thread.

[0017] Furthermore, the outer rotating sleeve is sleeved on the outside of the storage tube body. The outer rotating sleeve is a sleeve with a circular channel inside. The inner diameter of the port of the outer rotating sleeve near the tube cap is smaller than the diameter of the circular channel of the outer rotating sleeve. The port of the outer rotating sleeve is locked between the first limiting ring and the second limiting ring.

[0018] Furthermore, the leakage detection structure is a leakage detection test paper, and the leakage detection structure surrounds the storage tube body disposed between the external thread and the flange.

[0019] Furthermore, the preservation fluid tube also includes:

[0020] A marking line is placed on the storage tube to indicate the volume of liquid inside the storage tube.

[0021] Furthermore, the pipe cap includes:

[0022] Cover;

[0023] A swab clamping structure is disposed within the cap body and is configured as a funnel shape, with the conical inner surface of the funnel-shaped structure facing the preservation liquid tube; and

[0024] Internal threads are provided inside the cover body.

[0025] Furthermore, the pipe cap also includes:

[0026] Positioning slots are provided at the opening end of the cover and multiple slots are provided.

[0027] Furthermore, the storage liquid tube includes a flange, and when the tube cap is fixed to the storage liquid tube, the open end of the cap abuts against the flange.

[0028] A positioning block is provided on the side of the flange platform near the pipe cover. The number of positioning blocks is greater than or equal to the number of positioning slots. When the open end of the cover body abuts against the flange platform, the positioning block is engaged in the positioning slot.

[0029] Furthermore, the outer side of the cover is provided with anti-slip teeth.

[0030] Furthermore, a platform structure is provided on the outer side of the cover.

[0031] In summary, this application has the following beneficial effects:

[0032] 1. The sampling swab is used to collect samples. After sampling, the sampling swab can be fixed to the tube cap through the matching structure. This allows the sampling swab to be removed from the preservation liquid tube at the same time as the tube cap is removed when the test personnel take the sample for testing, thus avoiding interference from the sampling swab during the sample aspiration process.

[0033] 2. By setting an external rotating sleeve, when shaking is required after sampling, the operator can hold and fix the external rotating sleeve with one hand and rotate the preservation liquid tube with the other hand to achieve rapid mixing; furthermore, the external rotating sleeve can be clamped and fixed by an external fixing clamp (such as a clamp), and the preservation liquid tube can be rotated with one hand to achieve rapid mixing; even further, the preservation liquid tube can be rotated rapidly by an external automated device to further improve the mixing effect and efficiency.

[0034] 3. By setting up a leak detection structure, when the liquid in the storage tube leaks, the leak detection structure changes color after contacting the liquid, which can detect micro-leaks in time and reduce the risk of biological hazards. Attached Figure Description

[0041] The structure and effects of this application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the invention, not the entire structure.

[0042] Example

[0043] This application discloses a field space pathogenic microorganism sampling kit for public safety, referring to... Figures 1-5 The sampling kit includes an individually packaged sampling swab 2, and an individually packaged liquid tube assembly consisting of a preservation liquid tube 1, a tube cap 3, an outer rotating sleeve 4, and a leak detection structure 5.

[0044] The sampling swab 2 is used to collect samples. After sampling, the sampling swab 2 can be fixed to the tube cap 3 through the matching structure. This allows the sampling swab 2 to be removed from the preservation liquid tube 1 at the same time as the tube cap 3 is removed when the test personnel take the sample for testing, thus avoiding interference from the sampling swab 2 during the sample collection process.

[0045] The cap 3 is set at the open end of the storage liquid tube 1 to seal the storage liquid tube 1. The two can be connected in a detachable manner commonly used in the art. For example, in this embodiment, a threaded connection is used to achieve a detachable connection between the cap 3 and the storage liquid tube 1.

[0046] An outer rotating sleeve 4 is fitted over the preservation liquid tube 1. The outer rotating sleeve 4 is a sleeve with an internal circular channel, and the inner diameter of the port of the outer rotating sleeve 4 near the tube cap 3 is smaller than the diameter of the circular channel of the outer rotating sleeve 4. The preservation liquid tube 1 can rotate relative to the outer rotating sleeve 4. This arrangement allows the operator to hold and fix the outer rotating sleeve 4 with one hand and rotate the preservation liquid tube 1 with the other hand to achieve rapid mixing after sampling. Furthermore, the outer rotating sleeve 4 can be clamped and fixed by an external fixing clamp (such as a clamp), and the preservation liquid tube 1 can be rotated with one hand to achieve rapid mixing. Even further, the preservation liquid tube 1 can be rotated rapidly by an external automated device to further improve the mixing effect and efficiency.

[0047] The leak detection structure 5 is located at the connection between the cap 3 and the storage liquid tube 1. When the liquid in the storage liquid tube 1 leaks, the leak detection structure 5 changes color upon contact with the liquid. For example, in this embodiment, the leak detection structure 5 can be a test strip that surrounds the connection between the cap 3 and the storage liquid tube 1.

[0048] Reference Figure 3 and Figure 5 The storage tube 1 includes a storage tube body 101, a first limiting ring 102, a second limiting ring 103, a gear structure 104, an external thread 105, a flange 106, and a marking line 108.

[0049] Limiting ring 102 and limiting ring 203 are vertically spaced on the outer wall of the storage tube 101. The port of the outer rotating sleeve 4 is engaged between limiting ring 102 and limiting ring 203, allowing the storage liquid tube 1 to rotate relative to the outer rotating sleeve 4. Furthermore, limiting ring 102 is positioned below limiting ring 203, and limiting ring 102 is made of a deformable material (e.g., rubber). During the process of fitting the outer rotating sleeve 4 onto the side wall of the storage tube 101 from bottom to top, limiting ring 102 deforms first, allowing the port of the outer rotating sleeve 4 to pass through limiting ring 102. Subsequently, limiting ring 102 returns to its original shape, thus limiting the port of the outer rotating sleeve 4 and confining it between limiting ring 102 and limiting ring 203.

[0050] A gear structure 104 is disposed on the storage tube 101 and can mesh with an external automated device. Driven by the external automated device, the storage tube 101 rotates, improving the mixing effect and efficiency. In this embodiment, the gear structure 104 is disposed at the bottom end of the storage tube 101.

[0051] The external thread 105 is provided at the open end of the storage tube 101 and is used to engage with the internal thread 303 inside the tube cap 3 to achieve a detachable engagement between the tube cap 3 and the storage liquid tube 1.

[0052] A flange 106 is mounted on the storage tube 101 between the limiting ring 103 and the external thread 105. When the tube cap 3 is fixed to the storage liquid tube 1, the open end of the tube cap 3 301 abuts against the flange 106. Furthermore, a leakage detection structure 5 is mounted around the storage tube 101 between the external thread 105 and the flange 106. The flange 106 also facilitates automated filling; during filling, the flange 106 is positioned on both sides of the automatic filling channel for automatic feeding.

[0053] Indicator lines 108 are provided on the storage tube 101 to indicate the volume of liquid inside the storage tube 101. The number of indicator lines 108 can be set according to actual needs. For example, in this embodiment, two indicator lines 108 are provided, namely a 3mL indicator line and a 5mL indicator line.

[0054] Reference Figure 4 and Figure 5 The tube cap 3 includes a cap body 301, a swab clamping structure 302, an internal thread 303, a positioning groove 304, anti-slip teeth 305, and a platform structure 306.

[0055] The swab clamping structure 302 is disposed inside the cover 301. In this embodiment, the swab clamping structure 302 is configured as a funnel-shaped structure, with the inner conical surface of the funnel-shaped structure facing the preservation liquid tube 1. During sampling, the tube cover 3 is separated from the preservation liquid tube 1, the packaging of the sampling swab 2 is opened and the sampling swab 2 is taken out. After collecting the sample, the sampling swab 2 is inserted into the preservation tube 101, and then the tube cover 3 is re-fixed to the open end of the preservation liquid tube 1. At this time, guided by the inner conical surface of the swab clamping structure 302, the end of the sampling swab 2 is inserted into the slot in the middle of the funnel-shaped structure, thereby fixing the sampling swab 2 on the cover 301. When the mixture is mixed and tested, the tester removes the tube cover 3 and takes the sampling swab 2 out of the preservation liquid tube 1 at the same time, and then draws the sample liquid.

[0056] The internal thread 303 is provided inside the cover body 301 and is used to cooperate with the external thread 105 of the liquid storage tube 1 to realize the detachable connection between the tube cover 3 and the liquid storage tube 1.

[0057] Multiple positioning slots 304 are provided, all located at the open end of the cover 301. In this embodiment, four positioning slots 304 are provided, and the four positioning slots 304 are evenly distributed along the open end of the cover 301. A positioning block 107 is provided on the side of the flange platform 106 near the pipe cover 3. The number of positioning blocks 107 is greater than or equal to the number of positioning slots 304. In this embodiment, four positioning blocks 107 are also provided. When the open end of the cover 301 abuts against the flange platform 106, the positioning blocks 107 engage with the positioning slots 304, thereby achieving positioning.

[0058] Anti-slip teeth 305 are provided on the outside of the cover 301 to facilitate the rotation of the cover 3 for opening and closing.

[0059] Platform structure 306 is disposed on the outside of cover 301 to prevent the tube cover 3 from rolling. In this embodiment, two platform structures 306 are provided and disposed opposite to each other on both sides of cover 301, and the anti-slip teeth 306 are spaced into two unconnected parts.

[0060] The working principle of the on-site pathogenic microorganism sampling kit for public safety in this embodiment is as follows:

[0061] During sampling, the cap 3 is separated from the preservation liquid tube 1, the packaging of the sampling swab 2 is opened and the sampling swab 2 is taken out. After collecting the sample, the sampling swab 2 is inserted into the preservation tube body 101, and then the cap 3 is re-fixed to the open end of the preservation liquid tube 1. At this time, guided by the inner surface of the cone of the swab clamping structure 302, the end of the sampling swab 2 is inserted into the slot in the middle of the funnel-shaped structure, thereby fixing the sampling swab 2 on the cap body 301. Then the outer rotating sleeve 4 is fixed, and the preservation liquid tube 1 is rotated to make the liquid in the preservation liquid tube 1 fully mixed with the sample. When the mixture is fully mixed and tested, the tester removes the cap 3 and takes the sampling swab 2 out of the preservation liquid tube 1 at the same time, and then draws the sample liquid.

[0062] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
