Abstract
Description
Technical Field
[0001] This utility model relates to the field of biotechnology instruments, and more specifically, it relates to a swab sampling tube containing reagents and a swab sampling kit. Background Technology
[0002] Currently, EP tubes are used to collect throat and anal swabs from poultry. The buffer solution is usually a double-antibiotic glycerol PBS solution. Due to the characteristics of antibiotics, the solution needs to be used as soon as possible after adding the antibiotics. This limitation means that the solution needs to be prepared and used immediately.
[0003] Sampling is usually done using sterile swabs. After sampling, the swab is immersed in the buffer solution, which makes it impossible to operate evenly. As a result, the swab tip still contains a large number of viruses and cannot be well homogenized into the buffer solution. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a swab sampling tube containing reagents, which solves the technical problems of the need to prepare and use the sampling swab buffer solution fresh and the inability of residual viruses on the swab after sampling to be better retained in the buffer solution.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] A swab sampling tube containing reagents includes a tube body for holding reagents to be mixed, a cap threaded to the top of the tube body to prevent reagent leakage to the outside of the tube body, and a funnel portion sealingly disposed inside the tube body to divide the inner cavity of the tube body into a first cavity and a second cavity. The funnel portion has an isolation hole for inserting a swab from the first cavity into the second cavity, and an isolation membrane is disposed on the isolation hole. The reagents include antibiotic powder located in the first cavity and buffer solution located in the second cavity. The diameter of the isolation hole is 1-3 mm larger than the diameter of the swab.
[0007] Optionally, the tube cap has an internal hole for securing the cotton swab.
[0008] Optionally, the sidewalls of the cap are provided with anti-slip texture.
[0009] Optionally, the separator is made of medical-grade aluminum foil.
[0010] Optionally, the pipe body is made of PP material.
[0011] Optional, the tube body is made of brown material.
[0012] Optionally, the bottom of the tube is conical.
[0013] Optionally, the outer wall of the tube is provided with several capacity graduation lines.
[0014] Another objective of this invention is to provide a swab sampling kit, which includes the aforementioned swab sampling tube containing reagents and a cotton swab.
[0015] In summary, the above embodiments of this utility model have the following beneficial effects: By setting a first cavity and a second cavity separated by a separating membrane within the tube, antibiotic powder and buffer solution are independently placed respectively. During use, the separating membrane is punctured with a cotton swab, allowing the antibiotic powder and buffer solution to mix, thereby reducing buffer solution preparation time and enabling sampling to be performed at any time. Furthermore, the cotton swab expands in volume after being soaked in water; therefore, when pulling the swab out, it can be squeezed through the separating hole, retaining more of the sampled material within the sampling tube.

Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.
[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0023] This invention provides a swab sampling tube containing reagents, such as... Figure 1-4 As shown, the device includes a tube 1 for holding reagents that need to be mixed. A cap 2 is threaded onto the top of the tube 1 to prevent the reagents from leaking to the outside of the tube 1. Inside the tube 1, a funnel portion 13 is sealed to divide the inner cavity of the tube 1 into a first cavity 11 and a second cavity 12. The funnel portion 13 has an isolation hole 131 for inserting a cotton swab 4 from the first cavity 11 into the second cavity 12. An isolation membrane 3 is provided on the isolation hole 131. The reagents include antibiotic powder located in the first cavity 11 and a buffer solution located in the second cavity 12. The diameter of the isolation hole 131 is 1-3 mm larger than the diameter of the cotton swab 4.
[0024] In this embodiment, the antibiotic powder is a dual-antibiotic powder, the buffer solution is a PBS-glycerol mixture, and both the tube body 1 and the tube cap 2 are made of transparent PP material. The tube cap 2 is fixed to the top of the tube body 1 by a threaded connection. The tube body 1 consists of an inner tube 14 and an outer tube 15. The inner tube 14 contains the antibiotic powder, and the outer tube 15 contains the buffer solution. The inner tube 14 and the outer tube 15 are assembled into a single unit using existing technology to form the tube body 1. For example, matching threads are provided on the bottom sidewall of the inner tube 14 and the top sidewall of the outer tube 15. After initial tightening by rotation, ultrasonic welding is performed at the dividing line to seal the inner tube 14 and the outer tube 15. The isolation membrane 3 is fixed to the bottom of the funnel portion 13 by heat fusion or ultrasonic welding to seal the isolation hole 131. The diameter of the isolation hole 131 is 1-3 mm larger than the diameter of the straight part (non-cotton part) of the cotton swab 4. This diameter difference allows the cotton swab 4 to easily carry the anti-powder into the second cavity 12. When the cotton swab 4 is removed, the isolation hole 131 can also better squeeze the cotton swab head.
[0025] The preparation sequence of the swab sampling tube is as follows: the isolation membrane 3 is fixed to the isolation hole 131 of the funnel part 13 of the inner tube 14 by means of hot melting or ultrasonic welding. An appropriate amount of PBS glycerol mixture is added to the outer tube 15. Then the inner tube 14 is tightened onto the outer tube 15 to achieve preliminary fixation. The connection between the inner tube 14 and the outer tube 15 is then ultrasonically welded to obtain a tube body 1 with good sealing performance. Next, the dual antibody powder is added into the inner tube 14. Finally, the tube cap 2 is fastened onto the tube body 1 and tightened to achieve the effect of encapsulating the reagent.
[0026] The steps for using the swab sampling tube are as follows: Unscrew the cap 2 from tube body 1, insert the sampled swab 4 into the first cavity 11 and further puncture the isolation membrane 3 to allow the anti-inflammatory powder and PBS glycerol mixture to mix and obtain a buffer solution. Stir the buffer solution multiple times with the swab 4 to ensure that all components are evenly mixed, thus achieving the purpose of preparing and using immediately. Then remove the swab 4, tighten the cap 2, and place it on a tray for the laboratory technician to perform pathological analysis. During the removal of the swab 4, the tip of the swab 4 swells from being immersed in water and is squeezed by the isolation hole 131, causing more of the sampled pathogen (sample virus) to remain in the sampling tube.
[0027] Furthermore, such as Figure 1-4 As shown, the tube cap 2 has a sleeve hole (not shown in the attached diagram) for securing the swab 4. The swab 4 is inserted into the sleeve hole with an interference fit. This design facilitates the mixing of the buffer solution by the sampling personnel and allows the swab 5 to remain inside the tube 1 during transport back to the laboratory without needing to be removed immediately after sampling. This allows the virus sample to be more fully released into the buffer solution during transport vibration.
[0028] Furthermore, to improve the user experience, anti-slip texture 21 is provided on the side wall of the tube cap 2 to increase the friction between the tube cap 2 and the palm.
[0029] Furthermore, to meet sampling requirements, tube 1 is made of medical-grade PP material, and isolation membrane 3 is made of medical-grade aluminum foil.
[0030] Furthermore, in order to extend the shelf life of the mixture of anti-inflammatory powder and PBS glycerol, both tube body 1 and tube cap 2 are made of brown transparent PP material.
[0031] Furthermore, such as Figure 1 As shown, the bottom of tube 1 is conical. During centrifugation, the conical bottom helps to concentrate sample components such as precipitates or cells at the bottom tip, which facilitates subsequent operations, such as better preserving the precipitate when removing the supernatant and reducing sample loss.
[0032] Furthermore, the outer wall of tube 1 is provided with several capacity graduation lines (not shown in the attached figure). In this embodiment, the capacity of tube 1 is 5ml, corresponding to five capacity graduation lines, namely 1.0ml, 2.0ml, 3.0ml, 4.0ml and 5.0ml, which facilitates the sampling personnel to detect the volume of the buffer solution.
[0033] This utility model also provides a swab sampling kit, which includes the aforementioned swab sampling tube containing reagents and cotton swabs 4. The cotton swabs 4 are individually packaged in sterile packaging and are sold together with the swab sampling tube containing reagents.
[0034] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
