Description

Technical Field

[0001] The utility model belongs to the technical field of collection tubes, and particularly relates to a collection tube for nucleic acid enrichment. Background Technique

[0002] The collection tube for enrichment is a special test tube for collecting, preserving and transporting nucleic acid samples. It has a wide range of applications in the fields of medicine and biology, especially in virus detection and disease diagnosis. The collection tubes for enrichment can be divided into different types and specifications according to requirements. Common test tube types include disposable plastic test tubes, glass test tubes, etc. In terms of specifications, parameters such as the capacity, caliber, and length of the test tubes vary according to different application scenarios to meet different sampling needs.

[0003] However, during the nucleic acid collection process, sometimes it is necessary to break the cotton swab to better retain the sample in the test tube. Breaking the cotton swab requires certain skills and strength, and the operation methods of different operators may vary. When breaking the cotton swab, if the operation is improper, splashing or aerosol may be generated, thus increasing the biosafety risk. Especially when dealing with highly infectious samples, this risk is more significant. At the same time, for some cotton swabs that cannot be broken off at one time, the handling is rather troublesome.

[0004] Therefore, a collection tube for nucleic acid enrichment is designed to solve the above problems. Content of the Utility Model

[0005] To solve the problems raised in the above background technique. The utility model provides a collection tube for nucleic acid enrichment. Through the position limitation of the end of the cotton swab by the card slot, the user can easily break the cotton swab, and the broken cotton swab head splashes towards the inside of the collection tube body, solving the risk of the cotton swab head splashing outwards during this process. At the same time, the bottle cap can be threadedly connected to the collection tube body during the breaking process. When the bottle cap is rotated close to the limit position, the end of the cotton swab to be broken is clamped into the limiting groove, further preventing the risk of the collected sample splashing outwards during the breaking process, increasing the safety and practicability of the device. A cutting part is arranged at the end of the limiting groove, and the cutting part has a relatively sharp structure. When some cotton swabs are not broken at one time, the bent part of the cotton swab will become relatively soft and cannot be broken again. At this time, the bent part of the end of the cotton swab can be clamped into the limiting groove, and then the bottle cap is rotated. The bent part of the cotton swab is cut off by the cutting part at the end of the limiting groove, solving the problem that the cotton swab cannot be broken continuously when it is not broken at one time, and increasing the practicability of the device.

[0006] To achieve the above object, the utility model provides the following technical solution: A collection tube for nucleic acid enrichment, comprising a collection tube body, and further comprising a collection assembly arranged on the outer side of the end of the collection tube body;

[0007] A bottle cap is threadedly connected to the outer side of the end of the collection component. Four breaking grooves are annularly formed at the end of the collection tube body. A clamping groove is formed at the end of the breaking groove facing the inside of the collection tube body. Four limiting grooves are annularly arranged on the outer side of the end of the bottle cap.

[0008] Preferably, for a collection tube for nucleic acid enrichment of the present utility model, a cutting part is provided on the outer side of the end of the bottle cap.

[0009] Preferably, for a collection tube for nucleic acid enrichment of the present utility model, an inclined part is provided on the outer side of the end of the collection tube body.

[0010] Preferably, for a collection tube for nucleic acid enrichment of the present utility model, a rotating handle is fixedly connected to the outer surface of the bottle cap.

[0011] Preferably, for a collection tube for nucleic acid enrichment of the present utility model, a rubber ring is fixedly connected to the outer side of the end of the collection tube body. The material of the rubber ring is rubber. The outer side of the end of the bottle cap is in contact with the rubber ring.

[0012] Preferably, for a collection tube for nucleic acid enrichment of the present utility model, a hand grip is fixedly connected to the outer surface of the collection tube body. The material of the hand grip is silica gel.

[0013] Preferably, for a collection tube for nucleic acid enrichment of the present utility model, a plurality of partition plates are fixedly connected to the inner side of the end of the collection tube body.

[0014] Preferably, for a collection tube for nucleic acid enrichment of the present utility model, a suction cup is fixedly connected to the outer side of the end of the collection tube body.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: A collection component is added to this application. By limiting the position of the end of the cotton swab through the clamping groove, the user can easily break the cotton swab, and the broken cotton swab head splashes towards the inside of the collection tube body, solving the risk of the cotton swab head splashing outwards during this process. At the same time, the bottle cap and the collection tube body can be threadedly connected during the breaking process. When the bottle cap is rotated close to the limit position, the end of the cotton swab to be broken is clamped into the limiting groove, further preventing the risk of the collected sample splashing outwards during the breaking process, increasing the safety and practicality of the device. A cutting part is provided at the end of the limiting groove. The cutting part has a relatively sharp structure. When some cotton swabs are not broken at one time, the bent part of the cotton swab will become relatively soft and cannot be broken again. At this time, the bent part of the end of the cotton swab can be clamped into the limiting groove, and then the bottle cap is rotated. The cutting part at the end of the limiting groove cuts off the bent part of the cotton swab, solving the problem that the cotton swab cannot be broken continuously when it is not broken successfully at one time, and increasing the practicality of the device.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0025] As Figure 1 shown;

[0026] A collection tube for nucleic acid enrichment includes a collection tube body 1.

[0027] In this implementation: Common types of test tubes include disposable plastic test tubes, glass test tubes, etc. In terms of specifications, parameters such as the capacity, diameter, and length of the test tube vary depending on different application scenarios to meet different sampling requirements. However, during the accounting of the collection process, sometimes the cotton swab needs to be broken to better retain the sample in the test tube. Breaking the cotton swab requires certain skills and strength, and the operating methods of different operators may vary. When breaking the cotton swab, if the operation is improper, splashing or aerosol may be generated, thereby increasing the biosafety risk. Especially when dealing with highly infectious samples, this risk is more significant. At the same time, for some cotton swabs that cannot be broken at once, the handling is rather troublesome. To solve this technical problem, a collection component 2 is added on this basis.

[0028] Furthermore:

[0029] As Figures 1 to 4 shown:

[0030] Combined with the above content: A bottle cap 21 is threadedly connected to the outer side of the end of the collection component 2. Four breaking grooves 22 are annularly formed at the end of the collection tube body 1. A clamping groove 23 is formed at the end of the breaking groove 22 facing the inside of the collection tube body 1. Four limiting grooves 24 are annularly arranged on the outer side of the end of the bottle cap 21.

[0031] In this implementation: In this collection tube, the collection tube body 1 is a hollow tube body, and the material is plastic to prevent it from falling and breaking. At the same time, a rectangular-structured breaking groove 22 is annularly formed at the end of the collection tube body 1. The bottle cap 21 is threadedly connected to the outer side of the end of the collection tube body 1. At the same time, a clamping groove 23 is formed at one end of the breaking groove 22 facing the bottom of the collection tube body 1. When medical staff use this collection tube, they can insert the end of the cotton swab after collection into the inside of the breaking groove 22. At the same time, the clamping groove 23 is of an arc structure. The medical staff rotates the cotton swab by a certain angle so that the end of the cotton swab is inserted into the arc-structured clamping groove 23. At this time, the other end of the cotton swab can be broken off upward. Through the position limitation of the end of the cotton swab by the clamping groove 23, the user can easily break the cotton swab, and the broken cotton swab head splashes into the inside of the collection tube body 1, solving the risk of the cotton swab head splashing outward during this process. At the same time, the bottle cap 21 can be threadedly connected to the collection tube body 1 during the breaking process. When the bottle cap 21 is rotated close to the limit position, the end of the cotton swab to be broken is inserted into the inside of the limiting groove 24, further preventing the risk of the collected sample splashing outward during the breaking process, increasing the safety and practicability of the device.

[0032] It should be noted that: When the bottle cap 21 is rotated to the limit position, the limiting groove 24 and the breaking groove 22 are staggered, ensuring the sealing effect of the bottle cap 21.

[0033] Even further:

[0034] In an alternative embodiment, a cutting portion 25 is provided on the outer side of the end of the bottle cap 21, and a rotating handle 27 is fixedly connected to the outer surface of the bottle cap 21.

[0035] In this embodiment: A cutting portion 25 is provided at the end of the limiting groove 24. The cutting portion 25 has a relatively sharp structure. When some cotton swabs are not broken at one time, the bent portion of the cotton swab will become relatively soft and cannot be broken again. At this time, the bent portion at the end of the cotton swab can be clamped into the limiting groove 24, and then the bottle cap 21 is rotated. The bent portion of the cotton swab is cut off by the cutting portion 25 at the end of the limiting groove 24, solving the problem that the cotton swab cannot be broken continuously after the first break, increasing the practicability of the device. At the same time, the inclined portion 26 at the end of the collection tube body 1 can ensure that when the bottle cap 21 seals the collection tube body 1, medical staff can successfully sleeved the bottle cap 21 on the outer side of the end of the collection tube body 1 at one time. At the same time, the rotating handle 27 on the outer surface of the bottle cap 21 can assist medical staff in rotating the bottle cap 21, enhancing the user experience.

[0036] Furthermore:

[0037] In an alternative embodiment, a rubber ring 28 is fixedly connected to the outer side of the end of the collection tube body 1. The material of the rubber ring 28 is rubber. The outer side of the end of the bottle cap 21 is in contact with the rubber ring 28. A hand grip 29 is fixedly connected to the outer surface of the collection tube body 1. The material of the hand grip 29 is silicone.

[0038] In this embodiment: A rubber ring 28 is fixedly connected to the outer side of the end of the collection tube body 1. The material of the rubber ring 28 is rubber. Through the rubber ring 28 made of rubber, when the bottle cap 21 rotates to the limit position, the outer side of the end of the bottle cap 21 closely adheres to the rubber ring 28 and squeezes the rubber ring 28, minimizing the gap between the bottle cap 21 and the collection tube body 1 to the greatest extent, enhancing the sealing effect of the device and ensuring the accuracy of the collected sample. The material of the hand grip 29 on the outer surface of the collection tube body 1 is rubber. Through the hand grip 29, the friction force on the user's hand can be increased, preventing the device from falling from the hands of medical staff due to hand slippage.

[0039] Furthermore:

[0040] In an alternative embodiment, a plurality of partition plates 210 are fixedly connected to the inner side of the end of the collection tube body 1, and a suction cup 211 is fixedly connected to the outer side of the end of the collection tube body 1.

[0041] In this implementation: A number of partitions 210 are fixedly connected to the inner side of the end of the collection tube body 1. When the broken cotton swab head falls into the interior of the collection tube body 1, it will continue to fall into the compartments formed by the partitions 210. When medical staff are collecting multiple samples simultaneously, different cotton swab heads can fall into the compartments formed by different partitions 210, solving the problem that the volume and concentration occupied by each sample may be uneven, resulting in too low nucleic acid concentration of some samples, thus affecting the sensitivity of detection. A suction cup 211 is fixedly connected to the outer side of the end of the collection tube body 1. Through the suction cup 211, the collection tube body 1 can be adsorbed inside the container during transportation, increasing the stability of the device.

[0042] Working principle: In this collection tube, the collection tube body 1 is a hollow tube made of plastic to prevent it from falling and breaking. At the same time, a rectangular break groove 22 is annularly opened at the end of the collection tube body 1. The bottle cap 21 is threadedly connected to the outer side of the end of the collection tube body 1. At the same time, a clamping groove 23 is opened at one end of the break groove 22 facing the bottom of the collection tube body 1. When medical staff use this collection tube, they can insert the end of the cotton swab after collection into the inside of the break groove 22. At the same time, the clamping groove 23 is of an arc structure. The medical staff rotates the cotton swab by a certain angle so that the end of the cotton swab is inserted into the arc-shaped clamping groove 23. At this time, the other end of the cotton swab can be bent upward. Through the limitation of the end of the cotton swab by the clamping groove 23, the cotton swab can be easily broken, and the broken cotton swab head splashes into the inside of the collection tube body 1, solving the risk of the cotton swab head splashing outward during this process. At the same time, the bottle cap 21 and the collection tube body 1 can be threadedly connected during the breaking process. When the bottle cap 21 is rotated close to the limit position, the end of the cotton swab to be broken is inserted into the inside of the limit groove 24, further preventing the risk of the collected sample splashing outward during the breaking process, increasing the safety and practicality of the device. A cutting part 25 is opened at the end of the limit groove 24. The cutting part 25 is a relatively sharp structure. When some cotton swabs are not broken at one time, the bent part of the cotton swab will become relatively soft and cannot be broken again. At this time, the bent part of the end of the cotton swab can be inserted into the inside of the limit groove 24, and then the bottle cap 21 is rotated. The bent part of the cotton swab is cut off by the cutting part 25 at the end of the limit groove 24, solving the problem that the cotton swab cannot be broken continuously when it is not broken successfully at one time, increasing the practicality of the device. At the same time, the inclined part 26 at the end of the collection tube body 1 can ensure that when the collection tube body 1 is sealed by the bottle cap 21, the medical staff can successfully sleeved the bottle cap 21 on the outer side of the end of the collection tube body 1 at one time. At the same time, the rotating handle 27 on the outer surface of the bottle cap 21 can assist the medical staff to rotate the bottle cap 21, increasing the user experience. A rubber ring 28 is fixedly connected to the outer side of the end of the collection tube body 1. The material of the rubber ring 28 is rubber. Through the rubber ring 28 made of rubber material, when the bottle cap 21 is rotated to the limit position, the outer side of the end of the bottle cap 21 closely adheres to the rubber ring 28 and squeezes the rubber ring 28, minimizing the gap between the bottle cap 21 and the collection tube body 1 to the greatest extent, increasing the sealing effect of the device and ensuring the accuracy of the collected sample. The hand grip 29 on the outer surface of the collection tube body 1 is made of rubber. Through the hand grip 29, the friction force on the user's hand can be increased, preventing the device from falling from the hand of the medical staff due to the slippery hand of the medical staff. A plurality of partition plates 210 are fixedly connected to the inner side of the end of the collection tube body 1. When the broken cotton swab head falls into the inside of the collection tube body 1, it will continue to fall into the compartments formed by the partition plates 210. When the medical staff is collecting multiple samples at the same time, different cotton swab heads can fall into the compartments formed by different partition plates 210, solving the problem that the volume and concentration occupied by each sample may be uneven, resulting in too low nucleic acid concentration of some samples.Thus, regarding the problem of affecting the detection sensitivity, a suction cup 211 is fixedly connected to the outer side of the end of the collection tube body 1. Through the suction cup 211, the collection tube body 1 can be adsorbed inside the container during transportation, increasing the stability of the device.
