Description

Technical Field

[0001] The utility model relates to the field of medical inspection, in particular to a HPV screening cell preservation fluid test tube. Background Art

[0002] Liquid-based cytology is a part of exfoliative cytology. It is a process of placing exfoliated cytology specimens that are difficult to handle by traditional methods into an intermediate liquid to remove interfering components such as blood and mucus that affect the diagnosis, so as to improve the diagnosis rate. In view of the heavy outpatient workload and a large number of physical examinations of gynecologists, when taking samples for cervical liquid-based cytology and HPV virus testing, gynecologists need to put the brush head into the test tube and mix it with the liquid base in the test tube.

[0003] The Chinese patent with the announcement number CN219136770U discloses a HPV screening cell preservation fluid test tube that is convenient for breaking a cervical brush, comprising: a tube body, an inner core and a cover. The tube body is a tube with an opening at the top, and there is a notch at the opening. The inner core is embedded in the opening of the tube body, and there is a central channel in the middle. The entrance of the channel is lower than one-half of the notch, and the cover is detachably connected to the tube body. The beneficial effect of the utility model is that the breaking is completed through the central channel on the inner core and the central channel on the tube body. When used, the cervical brush is first placed in the central channel of the inner core, and then the tail end of the cervical brush is bent toward the notch, so that the head of the cervical brush is broken and falls directly from the central channel into the tube body to avoid the occurrence of ejection. In the above technical solution, the head of the cervical brush needs to be bent by hand during the breaking process, and there is no external auxiliary breaking force. It is impossible to determine whether it can be broken quickly and completely during the breaking process, and the success rate of breaking is not high, which reduces the subsequent detection efficiency.

[0023] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0024] First embodiment

[0025] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 This is a schematic structural diagram of the first embodiment of the HPV screening cell preservation fluid test tube provided by the utility model; Figure 2 A schematic diagram of a half-section structure of a HPV screening cell preservation fluid test tube provided by the utility model; Figure 3 for Figure 2 An enlarged schematic diagram of part A is shown; Figure 4 This is a schematic diagram of the main cross-sectional structure of the HPV screening cell preservation fluid test tube provided by the utility model; Figure 5 A schematic diagram of the structure of the tube cover of the HPV screening cell preservation fluid test tube provided by the utility model. The HPV screening cell preservation fluid test tube includes a tube body 4, a connecting portion 5 integrated with the tube body 4, an introduction port 3 arranged on one side of the connecting portion 5, and a tube cover 2 detachably connected to the connecting portion 5, an auxiliary breaking structure 1 for pressurizing the cervical brush head is arranged in the tube cover 2, and the auxiliary breaking structure 1 includes a pressure plate 13, the pressure plate 13 is arranged at the bottom of the pressure rod 12, and the pressure rod 12 is arranged on the surface of one side of the central sealing pad 11. Through the arrangement of the central sealing pad 11, the tube body 4 can be sealed, and the introduction port 3 can be sealed at the same time, thereby ensuring the sealing of the tube body 4;

[0026] A cutting edge 16 is provided on one side surface of the supporting portion 15, which can quickly break the cervical brush head and improve the success rate of breaking.

[0027] A guide block 14 is provided on the inner wall of the tube body 4 below the cutting edge 16 to facilitate the guide of the broken cervical brush head.

[0028] An arc-shaped guide portion 17 is provided on one side surface of the guide block 14 , and the end of the arc-shaped guide portion 17 is in contact with the cutting edge portion 16 , thereby preventing the cervical brush head from being stuck in the support portion 15 .

[0029] Graduation marks are arranged on the outer surface of the tube body 4 , and the tube cover 2 is detachably connected to the connecting portion 5 via threads, so as to facilitate observation of the liquid level in the tube body 4 and to facilitate disassembly of the tube cover 2 .

[0030] The working principle of the HPV screening cell preservation fluid test tube provided by the utility model is as follows:

[0031] First, separate the tube cover 2 from the tube body 4, then insert the cervical brush head from the tube mouth of the tube body 4 into the tube body 4, and make one end of the cervical brush head abut against the support part 15, extend the pressure plate 13 on the tube cover 2 into the tube body 4, and make the pressure plate 13 fit with the cervical brush head, press the tube cover 2 downward, and the tube cover 2 drives the pressure plate 13 to the downward end through the pressure rod 12. At this time, the support part 15 serves as a supporting point, and at the same time, the rod part of the cervical brush head is inserted into the introduction part. Under the downward thrust of the pressure plate 13, the cutting edge 16 can quickly break the cervical brush head, and the broken cervical brush head falls into the tube body 4 and mixes with the liquid base.

[0032] Compared with the related art, the HPV screening cell preservation fluid test tube provided by the utility model has the following beneficial effects:

[0033] The present application uses a pressure plate 13 in conjunction with a support portion 15.
