Description

Technical Field

[0001] The utility model relates to the technical field of biological sampling, in particular to a swab stick suitable for collecting cow uterine microorganisms. Background Art

[0002] The reproductive tract microbiome of dairy cows has a huge impact on endometrial health, homeostasis and fertility. The symbiotic reproductive tract microbiome largely determines the overall fertility of the cow. They play an important role in maintaining the structural integrity of the genital mucosal barrier, immune regulation and resistance to pathogens. In the past, microbial research mainly relied on traditional microbial culture methods, but this method has great limitations. It is estimated that less than 1% of microorganisms can be cultured in the laboratory, and many microorganisms cannot be cultured for research. With the continuous development of high-throughput sequencing technology (NGS), more types of microorganisms can be isolated and identified. At the same time, accurate sampling methods are the prerequisite for subsequent research. At present, the main methods for collecting cow uterine microorganisms are uterine flushing method and swab method. The former injects appropriate flushing fluid (such as saline) into the cow's uterus, and then recovers the flushing fluid to collect microbial samples in the uterus. The swab method is to use a swab to gently insert the cow's vagina, rotate or scrape the uterine wall and endometrium to collect microbial samples. However, due to the low abundance of uterine microorganisms, the flushing method is easily interfered by other contents, and the swab method is easily contaminated by the vagina or cervix during the process of entering the uterus, resulting in inaccurate subsequent detection and analysis.

[0003] Therefore, the inventor provides a swab stick suitable for collecting cow uterine microorganisms. Utility Model Content

[0028] Figure 1It is a structural schematic diagram of a swab stick suitable for collecting cow uterine microorganisms provided by an embodiment of the utility model. The swab stick may include a sampling swab 1, a protective tube 2 and a driving member 3. The sampling swab 1 is arranged in the protective shell 2. The first end of the protective tube 2 is provided with an opening 201. The driving member 3 is connected to the sampling swab 1 and is used to drive the sampling swab 1 to move along the length direction of the protective tube 2 to extend out of the opening 201 to collect cow uterine microorganisms.

[0029] In the above embodiment, the length of the sampling swab 1 is shorter than the length of the protection tube 2, so that the sampling swab 1 can be retractably installed in the protection tube 2. The length of the sampling swab 1 is generally preferably within the range of 55 to 60 cm.

[0030] The specific operation process of the swab stick is:

[0031] Wearing sterile long-arm gloves to grasp the rectum, insert the swab stick from the vulva into the vagina and pass through the cervix, push the sampling swab 1 out of the protection tube 2 through the driving part 3, wipe a circle in the cow's uterine cavity, put the sampling swab 1 back into the protection tube 2 through the driving part 3 again, then pull out the swab stick as a whole, quickly cut off the swab head and put it into the storage liquid. The entire collection process avoids contamination from cervical and vaginal microorganisms, and at the same time improves the efficiency of collecting uterine microorganisms.

[0032] As an optional implementation, Figure 1 As shown, the swab rod also includes an elastic element 4, which is sleeved on the first end of the sampling swab 1 close to the opening 201. The driving member 3 is a button, which is arranged at the second end of the protective tube 2. The driving member 3 is in contact with and connected to the second end of the sampling swab 1. When the driving member 3 presses the sampling swab 1, the sampling swab 1 is extended out of the opening 201 by squeezing the elastic element 4.

[0033] Specifically, Figure 1 As shown, the first end of the sampling swab 1 has a mounting boss 103 for mounting an elastic element 4, and the elastic element 4 is a spring. The specific structural form of the elastic element 4 is not limited, and a spiral spring is generally used. Furthermore, the first end of the protection tube 2 is a variable diameter contraction structure, and the diameter of the spring is greater than the diameter of the opening 201. Such a setting can prevent the spring from extending out of the opening 201 during the process of being squeezed by the sampling swab 1.

[0034] As an optional implementation, Figure 2As shown, a boss 202 is provided on the inner wall circumferentially of the second end of the protection tube 2, and a groove 301 matching with the boss 202 is provided along the outer wall circumferentially of the driving member 3, and the groove 301 cooperates with the boss 202 to realize the self-locking of the driving member 3. It should be noted that the self-locking form of the button is not limited to this embodiment, and a boss may be provided on the outer wall circumferentially of the driving member 3, and a groove may be provided on the inner wall circumferentially of the second end of the protection tube 2. Of course, it is not limited to the matching form of the boss and the groove, and the self-locking structure of the boss and the groove is relatively simple and has low processing cost.

[0035] As an optional implementation, Figure 3 As shown, the sampling swab 1 includes a sampling head body 101 and a spiral protrusion 102 coiled along the axial direction of the sampling head body 101. The setting of the spiral protrusion 102 can increase the contact area between the sampling swab 1 and the cow's uterus, so as to collect uterine microorganisms more quickly.
