Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a tubular disposable HPV tissue cell sampler. Background Technology

[0002] Human papillomavirus (HPV) is widespread in nature. It can be detected in 90% of cervical cancer tissues and 50%–75% of penile cancer tissues, with HPV type 16 being the predominant infection type. Currently, HPV tissue samplers typically consist of a swab and a preservation solution bottle. During sampling, the swab tip is inserted into the cervix, rotated for 4-5 seconds, held for about 10 seconds, and then removed. The end of the swab with the tip is then inserted into the preservation solution bottle. The part of the swab extending beyond the bottle is broken off, leaving the tip inside the bottle. The bottle is then closed. The swab and preservation solution bottle need to be packaged and stored separately. After sampling, the swab needs to be broken off, and during testing, both the broken swab and the tip need to be removed, which is quite cumbersome.

[0003] Based on the above problems, this utility model proposes a tubular disposable HPV tissue cell sampler. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a tubular disposable HPV tissue cell sampler. A partition is installed below the inner wall of the sampling tube, and a cavity cover is installed on top of the partition, so that the partition and the inner wall of the sampling tube form a preservation fluid cavity for holding the preservation solution. The swab rod can move axially along the threaded hole of the tube cover via a thread. Before sampling, the swab rod is moved upward along the threaded hole so that the swab head is above the cavity cover. After sampling, the cavity cover is discarded, and the swab rod can be moved downward along the threaded hole so that the swab head can be immersed in the preservation fluid in the preservation fluid cavity. This integrates the sampling tube and the preservation fluid bottle into one unit, making it more convenient to use and carry.

[0005] To achieve the objective of this utility model, the technical solution adopted by this utility model is as follows:

[0006] This utility model discloses a tubular disposable HPV tissue cell sampler, including a sampling tube, a tube cap, a swab rod, a swab head, a partition, and a cavity cap. The lower inner wall of the tube cap is threadedly connected to the upper outer wall of the sampling tube, which has a hollow cylindrical structure with an open top. The outer wall of the swab rod is provided with external threads, and the swab head is fixed to the bottom of the swab rod. The tube cap has a threaded hole in the axial direction that matches the external threads of the swab rod. The lower inner wall of the sampling tube is provided with an annular partition, and the lower surface of the partition and the inner wall of the sampling tube form a preservation fluid cavity for placing preservation fluid. The cavity cap is located in the middle of the top of the partition.

[0007] The tube cap includes a connecting ring and a hemispherical block. The hemispherical block has a hemispherical structure with a protruding top, and its bottom outer edge is connected to the top of the connecting ring. The inner wall of the connecting ring is threadedly connected to the upper outer wall of the sampling tube, which has a hollow cylindrical structure with an open top. The hemispherical block has a threaded hole in its axial direction that matches the external thread of the swab rod.

[0008] The cavity cover has a cylindrical structure with an outer diameter larger than the inner diameter of the partition. The cavity cover is fixed to the middle of the upper surface of the partition by a connecting mechanism.

[0009] The connecting mechanism includes a first connecting rod, the bottom ends of the two first connecting rods are connected to the top two sides of the cavity cover, and the top ends of the first connecting rods are connected to the bottom two sides of the hemispherical block; the upper outer wall of the first connecting rod is provided with a folding groove.

[0010] The folding groove has a ring-shaped structure and is located below the connecting ring.

[0011] The connecting mechanism includes a second connecting rod and a pressure ring. The bottom ends of the two second connecting rods are connected to the top two sides of the cavity cover, and the top ends of the second connecting rods are connected to the bottom inner ring two sides of the annular pressure ring. The outer diameter of the pressure ring is the same as the top outer diameter of the sampling tube, and the inner diameter of the pressure ring is not less than the outer diameter of the swab rod. When the lower surface of the pressure ring contacts the upper surface of the sampling tube, the lower surface of the cavity cover contacts the upper surface of the partition.

[0012] The partition includes a partition body and a blocking ring. The partition body has an annular structure, and its outer wall is fixedly connected to the lower inner wall of the sampling tube. The inner diameter of the partition body is not less than the outer diameter of the swab rod. The blocking ring has an annular structure, and its inner diameter is equal to the inner diameter of the partition body. The top of the blocking ring is connected to the bottom of the partition body. The longitudinal section of the blocking ring has a right-angled triangular structure, and its outer side wall is a hypotenuse.

[0013] A sampling tube connecting ring is provided on the upper part of the inner wall of the sampling tube. The outer diameter of the sampling tube connecting ring is equal to the inner diameter of the sampling tube. The outer wall of the sampling tube connecting ring is provided with an external thread that matches the internal thread of the inner wall of the connecting ring. The thickness of the connecting ring is equal to the wall thickness of the sampling tube. The height of the connecting ring is equal to the height of the sampling tube connecting ring.

[0014] The top of the swab rod is connected to a rotating block, which is a cylindrical structure with an outer diameter larger than that of the swab rod, and the outer wall of the rotating block is provided with anti-slip texture.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention integrates the sampling tube and the preservation solution bottle into one unit. A partition is installed at the bottom of the inner wall of the sampling tube, and a cavity cover is installed at the top of the partition. This creates a preservation solution cavity formed by the partition and the inner wall of the sampling tube. The swab rod can move axially along the threaded hole of the tube cover. Before sampling, the swab rod is moved upwards along the threaded hole so that the swab head is above the cavity cover. After sampling, the cavity cover is discarded, and the swab rod can move downwards along the threaded hole so that the swab head can be immersed in the preservation solution cavity. This design makes the sampling tube and the preservation solution bottle more convenient to use and carry. Furthermore, during sampling, the swab rod moves axially along the threaded hole to its lowest point, allowing the user to hold the tube cover for sampling, making it easier to apply force and enhancing usability.

Detailed Implementation

[0025] The present invention will be further described below:

[0026] Please see Figure 1-7 ,

[0027] This utility model discloses a tubular disposable HPV tissue cell sampler, such as Figure 1-7As shown, the device includes a sampling tube 1, a tube cap 2, a swab rod 3, a swab head 4, a partition 5, and a cavity cap 6. The lower inner wall of the tube cap 2 is threaded to the upper outer wall of the sampling tube 1, which has a hollow cylindrical structure with an open top. The outer wall of the swab rod 3 has external threads, and the swab head 4 is fixed to the bottom of the swab rod 3. The tube cap 2 has a threaded hole 23 on its axial direction that matches the external threads of the swab rod 3. The lower inner wall of the sampling tube 1 has an annular partition 5, and the lower surface of the partition 5 and the inner wall of the sampling tube 1 form a preservation fluid cavity 7 for placing the preservation fluid. The cavity cap 6 is located at the top center of the partition 5. This invention sets the partition 5 below the inner wall of the sampling tube 1 and the cavity cap 6 at the top of the partition 5, so that the partition 5 and the inner wall of the sampling tube 1 form a preservation fluid cavity 7 for placing the preservation fluid. The sample collection tube 1 and the sample collection tube bottle are integrated into one unit, making them more convenient to use and carry. The swab rod 3 can move axially along the threaded hole 23 of the tube cap 2. Before sampling, the swab rod 3 is moved upward along the threaded hole 23 so that the swab head 4 is positioned above the tube cap 6. After sampling, the tube cap 6 is discarded, and the swab rod 3 can move downward along the threaded hole 23 so that the swab head 4 can be immersed in the sample collection tube 7. This integrates the sample collection tube 1 and the sample collection tube bottle into one unit, making them more convenient to use and carry, and eliminating the need to break the swab rod 3. When a sample needs to be tested, the tube cap 2 can be unscrewed to remove the swab rod 3 and the swab head 4. Furthermore, during sampling, the swab rod 3 moves axially along the threaded hole 23 to its lowest position, allowing the user to hold the tube cap 2 for sampling, making it easier to apply force and more convenient to use.

[0028] Furthermore, the tube cap 2 includes a connecting ring 21 and a hemispherical block 22. The hemispherical block 22 has a hemispherical structure with a protruding top, and its bottom outer edge is connected to the top of the connecting ring 21. The inner wall of the connecting ring 21 is threadedly connected to the upper part of the outer wall of the sampling tube 1, which has a hollow cylindrical structure with an open top. The hemispherical block 22 has a threaded hole 23 in the axial direction that matches the external thread of the swab rod 3. By setting the hemispherical block 22, the length of the threaded hole 23 is relatively large, and the swab rod 3 can move stably along the axial direction of the threaded hole 23.

[0029] Furthermore, the cavity cover 6 has a cylindrical structure with an outer diameter larger than the inner diameter of the partition 5. The cavity cover 6 is fixed to the middle of the upper surface of the partition 5 by a connecting mechanism 8. Before sampling, the cavity cover 6 can seal the top of the inner ring of the partition 5 to ensure that the preservation liquid will not leak out accidentally. Preferably, the cavity cover 6 can be made of rubber for stronger sealing.

[0030] Example 1: As Figure 2-5As shown, the connecting mechanism 8 includes a first connecting rod 81. The bottom ends of the two first connecting rods 81 are connected to the top two sides of the cavity cover 6, and the top ends of the first connecting rods 81 are connected to the bottom two sides of the hemispherical block 22. An easy-break groove 82 is provided on the upper part of the outer wall of the first connecting rod 81. Before sampling, the cavity cover 6 is fixed to the top middle of the partition 5 by the two first connecting rods 81. After the swab head 4 finishes sampling, the first connecting rod 81 is broken through the easy-break groove 82. The lower end of the first connecting rod 81 and the cavity cover 6 are discarded, and the tube cover 2 is put on. At this time, the swab head 4 can be immersed in the preservation liquid in the preservation liquid cavity 7 through the inner ring of the partition 5.

[0031] Furthermore, the easy-break groove 82 has a ring structure, and the height of the easy-break groove 82 is slightly lower than the bottom of the connecting ring 21, which allows the user to easily break off the lower end of the first connecting rod 81 while the upper end of the first connecting rod 81 will not affect the insertion of the swab rod 3 into the cervix for sample collection.

[0032] Example 2: As Figure 6 and Figure 7 As shown, the connecting mechanism 8 includes a second connecting rod 83 and a pressure ring 84. The bottom ends of the two second connecting rods 83 are connected to the top two sides of the cavity cover 6, and the top ends of the second connecting rods 83 are connected to the bottom inner ring two sides of the annular pressure ring 84. The outer diameter of the pressure ring 84 is the same as the top outer diameter of the sampling tube 1, and the inner diameter of the pressure ring 84 is not less than the outer diameter of the swab rod 3. When the lower surface of the pressure ring 84 contacts the upper surface of the sampling tube 1, the lower surface of the cavity cover 6 contacts the upper surface of the partition 5. In this embodiment, by setting the pressure ring 84 to be clamped between the bottom of the hemispherical head 22 and the top of the sampling tube 1, a rigid connection is not required. When using a swab for sampling, the tube cover 2 can be unscrewed, and the pressure ring 84 along with the cavity cover 6 can be taken out and discarded, making the process more convenient.

[0033] Furthermore, such as Figure 4 As shown, the partition 5 includes a partition body 51 and a blocking ring 52. The partition body 51 has an annular structure, and its outer wall is fixedly connected to the lower inner wall of the sampling tube 1. The inner diameter of the partition body 51 is not less than the outer diameter of the swab rod 3. The blocking ring 52 has an annular structure, and its inner diameter is equal to the inner diameter of the partition body 51. The top of the blocking ring 52 is connected to the bottom of the partition body 51. The longitudinal section of the blocking ring 52 has a right-angled triangular structure, and its outer side wall is a hypotenuse. By setting the blocking ring 52, when the swab head 4 is immersed in the preservation liquid in the preservation liquid chamber 7 after sampling, the situation where the preservation liquid is shaken out of the inner ring of the partition 5 due to the shaking of the sampling tube 1 will be reduced.

[0034] Furthermore, such as Figure 1As shown, a sampling tube connecting ring 11 is provided on the upper part of the inner wall of the sampling tube 1. The outer diameter of the sampling tube connecting ring 11 is equal to the inner diameter of the sampling tube 1. The outer wall of the sampling tube connecting ring 11 is provided with an external thread that matches the internal thread of the inner wall of the connecting ring 21. The thickness of the connecting ring 21 is equal to the wall thickness of the sampling tube 1. The height of the connecting ring 21 is equal to the height of the sampling tube connecting ring 11. This allows the sampling tube 1 and the tube cap 2 to fit more tightly and more aesthetically pleasingly after connection.

[0035] Furthermore, such as Figure 1 As shown, a rotating block 9 is connected to the top of the swab rod 3. The rotating block 9 is a cylindrical structure with an outer diameter larger than that of the swab rod 3. The outer wall of the rotating block 9 is provided with anti-slip texture. By setting the rotating block 9, the swab rod 3 can rotate along the threaded hole 23 through its external thread, and it can also play a positioning role. When the bottom of the rotating block 9 contacts the top of the hemispherical block 22, sampling can be performed.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
