Description

Technical Field

[0001] This utility model relates to a fecal cryopreservation tube, belonging to the field of medical device technology. Background Technology

[0002] Cryopreservation tubes are commonly used containers by medical professionals or laboratory researchers for long-term cryopreservation of feces. Typically, the donor places the sample into the cryopreservation tube, and when the medical professional or researcher needs to use it, the cryopreservation tube needs to be opened, and then other devices are used to extract the sample and place it back into the cryopreservation tube. Utility Model Content

[0003] The purpose of this invention is to provide a fecal cryopreservation tube that integrates sampling and cryopreservation functions, eliminating the need for an additional fecal collection device to collect samples and then transfer them into the cryopreservation tube, thus reducing the complexity of the operation.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A fecal cryopreservation tube includes a tube body and a cap screwed onto the tube body. A sealing ring is formed inside the cap body to seal the tube body by inserting it into the port of the tube body. A sampling rod extending into the tube body is coaxially disposed inside the cap body located inside the sealing ring. The end of the sampling rod away from the cap body forms a groove structure.

[0005] Preferably, the outer surface of the cover is provided with anti-slip texture.

[0006] Preferably, a closed ring is formed outside the tube body, and after the cap is screwed onto the tube body, the end of the cap abuts against the closed ring.

[0007] Preferably, the tube body is a transparent structure.

[0008] Preferably, a support sleeve is also provided outside the tube body, the tube body has a corresponding outward protrusion, and the support sleeve has a groove for the outward protrusion to be inserted into.

[0009] Preferably, the bottom surface of the support sleeve is a planar structure.

[0010] Preferably, a scale line is provided on one of the outward protrusions of the tube body.

[0011] The beneficial effects of this utility model are as follows: Because it comes pre-equipped with a sampling rod, samples can be taken directly using cryovials and then frozen, reducing the complexity of the operation. Furthermore, no additional sampler is needed when the sample needs to be removed from the tube. The sealing ring seals the tube openings, preventing sample leakage. Attached Figure Description

[0013] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0014] This embodiment provides a fecal cryopreservation tube, such as Figure 1 As shown, it includes a pipe body 1, a cover body 2, and a support sleeve 3. Figure 2 As shown, the tube body 1 is a transparent structure. Two protrusions 4 are formed on the side wall of the tube body 1, and a scale line 5 is formed on one of the protrusions 4. A closed ring 6 is formed on the outside of the tube body 1 above the protrusion 4, and an external thread 7 is formed on the outside of the tube body 1 above the closed ring 6.

[0015] like Figure 3 As shown, the support sleeve 3 has a groove corresponding to the outward protrusion 4, and the bottom surface of the support sleeve 3 is a flat structure to facilitate vertical placement. During assembly, the support sleeve 3 is fitted from the bottom end of the tube body 1 to the outside of the tube body 1, and the outward protrusion 4 on the tube body 1 is correspondingly embedded in the groove of the support sleeve 3.

[0016] like Figure 4 As shown, the inner wall of the cover 2 has an internal thread 8 that matches the external thread 7 on the tube 1, and the outer wall of the cover 2 has anti-slip texture 9. A sealing ring 10 is also formed inside the cover 2 for inserting into the port of the tube 1 to seal the tube 1 (preventing sample leakage from the tube 1). Simultaneously, a sampling rod 11 is coaxially arranged inside the cover 2 located within the sealing ring 10, with a groove structure formed at the end of the sampling rod 11 furthest from the cover 2. In practical applications, the cover 2, sealing ring 10, and sampling rod 11 are integrally formed.

[0017] During assembly, the sampling rod 11 is first inserted into the tube body 1. Then, the cover 2 is screwed onto the tube body 1 using the thread on the cover 2 that is compatible with the tube body 1. At this time, the sealing ring 10 will be inserted into the tube body 1 and abut against the inner wall of the port of the tube body 1. At the same time, the end of the cover 2 abuts against the sealing ring 6.

[0018] During sampling, simply unscrew the cap 2. Since the cap 2 and sampling rod 11 are integrally formed, the sampling rod 11 will be removed together. Then, use the groove structure at the end of the sampling rod 11 to collect the fecal sample. After sampling, simply transfer the sample directly into the tube 1 and observe the sample volume through the scale line 5. After sampling, simply screw the cap 2 back onto the tube 1 for freezing. When it is necessary to remove the fecal sample, the sample can be removed from the tube 1 using the sampling rod 1; no additional sampler is required.

[0019] The above description is only a preferred embodiment of this utility model patent. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model patent, and these improvements and modifications should also be considered within the scope of protection of this utility model patent.
