Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, in particular to a vaginal flora sampling device for assisting hormone therapy. Background Art

[0002] The composition and health of vaginal flora are related to the hormone levels in women. Changes in hormone levels, especially estrogen levels, will affect the microenvironment in the vagina, and thus affect the balance of vaginal flora. The following are several ways to determine whether hormones are normal through vaginal flora testing:

[0003] Vaginal pH measurement: When estrogen levels are high, vaginal epithelial cells secrete more glycogen, and Lactobacillus converts glycogen into lactic acid to maintain the acidic environment of the vagina (pH is usually less than 4.5). If the pH value is elevated, it may indicate low estrogen levels or dysbiosis.

[0004] Assessment of flora density and diversity: The density and diversity of vaginal flora can reflect the health of the microecology. Changes in estrogen levels can affect these parameters, thereby affecting the balance of vaginal microecology.

[0005] Analysis of dominant flora: Lactobacillus is the dominant bacteria in normal vaginal flora, especially Lactobacillus crispatus, which is associated with a healthy microbiome. If the test finds a decrease or absence of Lactobacillus, it may indicate that estrogen levels are affected or the flora is unbalanced.

[0006] Inflammatory response observation: Observation of the body's inflammatory response, such as white blood cell counts, can provide clues about the vaginal microecological environment. Changes in estrogen levels may affect local immune responses and the number of inflammatory cells.

[0007] Functional testing: For example, hydrogen peroxide concentration measurement can assess the functional status of Lactobacillus. Hydrogen peroxide produced by Lactobacillus is important for maintaining vaginal health, and changes in estrogen levels may affect its production.

[0008] Microbiome analysis: Through more in-depth microbiome analysis, it is possible to identify changes in microbial species and abundance associated with specific hormone levels. For example, some studies have associated specific vaginal microbial communities (CSTs, Community State Types) with different vaginal health states.

[0009] Clinical evaluation: Vaginal flora testing should be combined with clinical symptoms and other test results for comprehensive evaluation. For example, if a patient has symptoms of vaginitis and vaginal flora testing shows abnormalities, further testing of hormone levels may be necessary.

[0010] Sampling for vaginal flora testing is usually performed at a specific location in the vagina to ensure that a representative sample is obtained. The main sampling method currently is to use 1-3 sterile swabs to rotate and sample at 1 / 3 of the vaginal side wall. This requires the sampling medical staff to have a relatively accurate judgment of the length of the vagina, and the sampling process is likely to cause discomfort to the person being tested.

[0033] A vaginal flora sampling device for assisting hormone therapy according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0034] See also Figure 1According to an embodiment of the utility model, a vaginal flora sampling device for assisting hormone therapy comprises a sampling brush head 1, a protective straight tube 2, and a first elastic airbag 3. The sampling brush head 1 is rigidly connected to the first elastic airbag 3 through a rigid first linear gas pipeline 4, and the first linear gas pipeline 4 extends into the protective straight tube 2. By pushing forward or pulling backward the first elastic airbag 3 located outside the protective straight tube 2, the sampling brush head 1 can be extended or retracted into the protective straight tube 2. During the sampling process, the first elastic airbag 3 is pushed forward to make the sampling brush head 1 extend out of the protective straight tube 2, as shown in FIG. Figure 2 or Figure 3 As shown, the sampling brush head 1 is used to contact the side wall of the vagina to collect samples required for vaginal flora detection.

[0035] Specifically, see Figure 4 and Figure 5 The sampling brush head 1 includes a second elastic airbag 5 that is generally in the shape of a round rod, a plurality of hair groups 6 that are circumferentially and evenly distributed along the outer peripheral wall of the second elastic airbag 5, and a rigid second linear gas pipe 7 that rigidly connects the first linear gas pipe 4 and the second elastic airbag 5. The first elastic airbag 3 and the second elastic airbag 5 are both filled with gas to maintain the shapes of the first elastic airbag 3 and the second elastic airbag 5. When the first elastic airbag 3 is pressurized, the internal gas can enter the second elastic airbag 5 through the first linear gas pipe 4 and the second linear gas pipe 7 to increase the volume of the second elastic airbag 5. For example, the first elastic airbag 3 is pushed forward to make the sampling brush head 1 extend out of the protective straight tube 2, that is, the vaginal flora sampling device for auxiliary hormone therapy is extended from Figure 1 The state shown is converted to Figure 2 In the state shown, the first elastic airbag 3 is then pressed, so that the gas in the first elastic airbag 3 enters the second elastic airbag 5 through the first linear air conduit 4 and the second linear air conduit 7, and the volume of the second elastic airbag 5 increases until its villus group 6 can effectively contact the vaginal side wall, that is, the vaginal flora sampling device for auxiliary hormone therapy is Figure 2 The state shown is converted to Figure 3 The second elastic airbag 5 is preferably made of silica gel.

[0036] Each of the fluff groups 6 includes a long strip base 8 and fluff 9 fixed on the base 8. The base 8 can be made of hard plastic, and the fluff 9 can be made of short fibers such as polyester fiber and nylon. Each of the bases 8 is circumferentially distributed at equal intervals along the outer peripheral wall of the second elastic airbag 5, fixed to the outer peripheral wall of the second elastic airbag 5, and arranged parallel to the virtual axis of the second elastic airbag 5.

[0037] A second constraint plate 10 in a circular shape is fixed in the middle of one end of the second elastic airbag 5. The through hole in the middle of the second constraint plate 10 is connected to the second elastic airbag 5 and the second linear gas pipeline 7. The second linear gas pipeline 7 is fixedly connected to the second constraint plate 10. During the sampling process, the sampling brush head 1 can be driven to rotate by rotating the first elastic airbag 3. The addition of the second speed plate can disperse the force driving the second elastic airbag 5 to rotate, effectively preventing the second elastic airbag 5 from being torn.

[0038] In this embodiment, the number of the villi groups 6 is 4. Figure 3 In the state shown in the vaginal flora sampling device for auxiliary hormone therapy, the first elastic airbag 3 drives the sampling brush head 1 to rotate 90 degrees, so as to realize rotation sampling on the vaginal side wall. Of course, the number of the villus groups 6 can also be 2, 3, 5, 6, etc., and the angle required for the first elastic airbag 3 to rotate to realize rotation sampling is at least 360° / N, where N is the number of the villus groups 6.

[0039] After completing the rotation sampling, the first elastic airbag 3 is released. Under the action of the restoring force of the first elastic airbag 3 and the second elastic airbag 5, the first elastic airbag 3 contracts and the second elastic airbag 5 extends. Part of the gas in the second elastic airbag 5 enters the first elastic airbag 3 through the middle through hole of the second constraint plate 10, the second straight gas pipeline 7, and the first straight gas pipeline 4 in sequence. Then, the first elastic airbag 3 is pulled backward to retract the sampling brush head 1 into the protective straight tube 2. Figure 1 In the state shown, the sampling brush head 1 is separated from the inner wall of the protective straight tube 2, and then the vaginal flora sampling device for auxiliary hormone therapy is pulled out of the vagina as a whole.

[0040] In order to make the sampling brush head 1 move and rotate more smoothly, at least two guide rings 11 may be sleeved on the outer periphery of the first straight gas pipeline 4 , and the outer peripheral wall of the guide ring 11 cooperates with the inner peripheral wall of the protective straight pipe 2 .

[0041] The first linear gas pipeline 4 and the second linear gas pipeline 7 can be connected by threads. After the vaginal flora sampling device for auxiliary hormone therapy is pulled out of the vagina as a whole, the first elastic airbag 3 is pushed forward to make the sampling brush head 1 extend out of the protective straight tube 2, and the sampling brush head 1 is rotated to separate the first linear gas pipeline 4 and the second linear gas pipeline 7, so that the sampling is completed.

[0042] A first circular constraint plate 12 is fixed to the middle of the other end of the second elastic airbag 5. The first constraint plate 12 is symmetrically arranged with the second constraint plate 10, and the two have the same outer diameter. Under the constraints of the first constraint plate 12, the second constraint plate 10 and the bases 8, the second elastic airbag 5 can always maintain an overall round rod shape during the process of receiving gas from the first elastic airbag 3 or discharging part of the gas.

[0043] When the vaginal flora sampling device for auxiliary hormone therapy is used to rotate and sample at 1 / 3 of the vaginal side wall, the amplitude of the rotation sampling is small, which effectively reduces the discomfort of the person being tested during the sampling process.

[0044] In order to more accurately determine that the sampling point is 1 / 3 of the vaginal side wall, the outer peripheral wall of the protection straight tube 2 is marked with a scale, and the scale is used to express the distance between the position of the corresponding scale and the front end of the protection straight tube 2. After the protection straight tube 2 is extended to the front end of the vagina, it retreats 1 / 3 according to the scale, and then controls the first elastic airbag 3 to perform rotation sampling.

[0045] Preferably, a transition portion 13 that bends gradually inward is formed at the front end of the protective straight tube 2 to reduce discomfort felt by the person being tested when the protective straight tube 2 is inserted into the vagina.

[0046] The vaginal flora sampling device for auxiliary hormone therapy may also include a positioning ring 14 sleeved on the outer peripheral wall of the protective straight tube 2 and capable of moving along the length direction of the protective straight tube 2. After the protective straight tube 2 is retracted by 1 / 3, the positioning ring 14 can be moved to the corresponding scale to facilitate observation of whether the protective straight tube 2 moves accidentally during the sampling process.

[0047] In this embodiment, the vaginal flora sampling device for auxiliary hormone therapy further includes a handle 15. The handle 15 is fixedly connected to the end of the protective straight tube 2, and the handle 15 is formed with a through hole, through which the first linear gas pipeline 4 extends into the protective straight tube 2.
