Description
Technical Field
[0001] This utility model relates to the field of sampling tubes, and in particular to a novel FOB sampling tube. Background Technology
[0002] FOB sampling refers to the process of extracting occult blood components from biological samples during FOB testing. The principle of FOB testing is to determine whether a patient has a disease by detecting occult blood components in biological samples. FOB sampling tubes are the tubes that hold these biological samples. Often, multiple test tubes containing different samples are placed together and transported to the testing laboratory for testing. Due to the shaking during transportation, leakage of samples inside the test tubes often occurs, affecting the sample testing and causing trouble in handling and sample confusion. Therefore, this application proposes a novel FOB sampling tube. Utility Model Content

This invention proposes a new type of FOB sampling tube.
[0004] The technical solution of this utility model: a novel FOB sampling tube, comprising a tube body and a sealing cap mechanism fixed to the top of the tube body, the sealing mechanism comprising a sealing ring threaded to the outer wall of the tube body, a sealing cap plate fixedly connected to the top of the sealing ring, and a sampling mechanism provided at the top of the sealing cap plate.
[0005] The outer wall of the tube is provided with a sealing and fastening mechanism, which includes a sliding ring slidably connected to the outer wall of the tube. A rubber layer is fixedly connected to the top of the sliding ring, and a buffer ring is fixedly connected to the bottom of the sliding ring. Multiple buffer terminals are fixedly connected to the inner wall of the buffer ring, and a guide tube is fixedly connected to the end of the multiple buffer terminals away from the buffer ring. The tube is sleeved on the bottom of the outer wall of the guide tube.
[0006] Optionally, the sampling mechanism includes a sampling port fixed to the top of the sealing cover plate, the inner wall of the sampling port is provided with two internal sealing rings, and the top of the inner wall of the sampling port is slidably connected to a cap.

[0026] like Figure 1 - Figure 4As shown, the novel FOB sampling tube proposed in this utility model includes a tube body 1 and a sealing cap mechanism fixed to the top of the tube body 1. The sealing mechanism includes a sealing ring 27 threadedly connected to the outer wall of the tube body 1. A sealing cap plate 2 is fixedly connected to the top of the sealing ring 27. A sampling mechanism is provided at the top of the sealing cap plate 2. The sampling mechanism includes a sampling port 21 fixed to the top of the sealing cap plate 2. Two internal sealing rings 23 are embedded in the inner wall of the sampling port 21, and a cap 22 is slidably connected to the top of the inner wall of the sampling port 21. By setting the cap 22, when the device needs to extract a sample, the cap 22 can be directly removed to extract the internal sample without unscrewing the sampling tube sealing cap, thus preventing the internal sample from spilling. A connecting block 24 is fixedly connected to one side of the outer wall of the cap 22. A rotating block 25 is rotatably connected to the wall. A connecting line 26 is fixedly connected to one end of the rotating block 25 away from the connecting block 24. The other end of the connecting line 26 away from the rotating block 25 is fixedly connected to one side of the top of the sealing cover plate 2. By setting the rotating block 25 and the connecting line 26, the cover plate 22 is prevented from falling off, and the sealed tube body 1 can continue to be used. A sealing ring 27 is fixedly connected to the bottom of the outer wall of the sampling port 21. The sealing ring 27 is made of rubber. By setting the sealing ring 27, leakage will not occur at the connection between the sampling port 21 and the sealing cover plate 2. A sampling guide port 28 is fixedly connected to the inner wall of the tube body 1. The sampling guide port 28 is located at the center position directly below the cover plate 22. By setting the sampling guide port 28, the device can better enter the tube body 1 when sampling with a needle, without puncturing the target.
[0027] It is necessary to describe in more detail, such as Figure 1 and Figure 3 As shown, a sealing and fastening mechanism 3 is provided on the outer wall of the pipe body 1. The sealing and fastening mechanism 3 includes a sliding ring 32 slidably connected to the outer wall of the pipe body 1. A rubber layer 33 is fixedly connected to the top end of the sliding ring 32, and a buffer ring 34 is fixedly connected to the bottom end of the sliding ring 32. Multiple buffer terminals 35 are fixedly connected to the inner wall of the buffer ring 34. A guide tube 36 is fixedly connected to the end of the multiple buffer terminals 35 away from the buffer ring 34. The pipe body 1 is sleeved on the bottom end of the outer wall of the guide tube 36. Multiple through tubes 3 are fixedly connected to the outer walls of both the sealing cover plate 2 and the sliding ring 32. 7. Each of the inner walls of multiple through-tubes 37 is slidably connected with a fastening rod 31. The bottom end of each of the multiple fastening rods 31 is connected to a buffer ring 34. There are three fastening rods 31. Through the fastening rods 31 slidably connected inside the through-tubes 37, the buffer ring 34 can drive the sliding ring 32 to slide upward, thereby fastening and sealing the connection between the sealing cover plate 2 and the tube body 1. At the same time, through the multiple buffer terminals 35 provided on the inner wall of the buffer ring 34, the sampling tube can better mitigate the impact force when it encounters external impact, thus better protecting the sampling tube.
[0028] In this embodiment, the internal sealing ring 23 embedded in the inner wall of the sealing cover plate 2 and the sampling port 21 makes the biological specimen on the inner wall of the device more tightly sealed. When the specimen needs to be extracted, the cover 22 can be removed directly. By setting the rotating block 25 and the connecting line 26, the cover 22 is prevented from falling off, making it easier to take out the internal sample. The fastening rod 31 slidably connected inside the through tube 37 allows the buffer ring 34 to drive the sliding ring 32 to slide upward, which tightens and seals the connection between the sealing cover plate 2 and the tube body 1. At the same time, the multiple buffer terminals 35 set in the inner wall of the buffer ring 34 can better alleviate the impact force when the sampling tube encounters external impact, and better protect the sampling tube.
[0029] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
