Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a vaginal secretion sampling device. Background Art

[0002] Clinically, during a gynecological examination of a patient, sampling and testing vaginal secretions is a common examination item. Usually, medical staff will use a cotton swab to collect the patient's vaginal secretions for subsequent inspection and analysis of the collected vaginal secretions.

[0003] During the process of sampling vaginal secretions, medical staff usually choose to insert a cotton swab deep into the vagina for sampling. For example, sampling is performed in the posterior fornix of the vagina, and the samples inside the vagina can more comprehensively reflect the pathogens and cell conditions in the vagina, thereby improving the accuracy of detection. However, during the process of inserting the cotton swab deep into the vagina, the cotton swab head may come into contact with the inner wall at the vaginal orifice, causing the cotton swab head to pick up the secretions on the inner wall at the vaginal orifice. Subsequently, when the cotton swab samples the secretions deep in the vagina, the extracted sample will be a mixture of the secretions deep in the vagina and the secretions in the shallow part of the vagina. Since, generally, there are differences between the secretions deep in the vagina and the secretions in the shallow part of the vagina, after the secretions deep in the vagina are contaminated by the secretions in the shallow part of the vagina, it is difficult to accurately reflect the pathogens and cell conditions in the vagina during subsequent inspection of the secretions, and thus it is difficult to improve the accuracy of detection.

[0004] Therefore, how to improve the purity of the secretions deep in the vagina extracted to improve the accuracy of subsequent detection of the secretions deep in the vagina is a technical problem that urgently needs to be solved at present. Summary of the Invention

[0005] The purpose of the present invention is to provide a vaginal secretion sampling device and a storage device to solve the situation where the secretions deep in the vagina extracted are contaminated by the secretions in the shallow part of the vagina during sampling of the secretions deep in the vagina at present, so as to achieve the purpose of improving the purity of the secretions deep in the vagina extracted and improving the accuracy of subsequent detection of the secretions deep in the vagina.

[0006] To achieve the above invention purpose, the present invention provides the following technical solutions: A vaginal secretion sampling device, comprising a sampler, the sampler includes a first cylinder and a second cylinder, the second cylinder is sleeved outside the first cylinder, an extraction component is arranged in the first cylinder, the extraction component includes a base and a cotton swab head, the base is connected to the cotton swab head, the base contacts the inner wall of the first cylinder, and the base can move relative to the first cylinder along the length direction of the first cylinder; the first cylinder includes a first cylinder body and a deformation part, the deformation part is located at the end of the first cylinder for extending into the vagina, the deformation part has elasticity, the deformation part has an initial state, and when the deformation part is in the initial state, the deformation part is in a closed-mouth shape; The sampler further includes a sleeve body, the sleeve body is in a cylindrical film structure, the sleeve body is turned over from inside the first cylinder through the deformation part and extends to the second cylinder, so that one end of the sleeve body is connected to the second cylinder and the other end is connected to the extraction component; The sampler has a first state and a second state. When the sampler is in the first state, the base contacts the inner wall of the first cylinder body, the deformation part is in the initial state, and the cotton swab head is blocked by the sleeve body; in the process of the sampler changing from the first state to the second state, the first cylinder moves relative to the second cylinder, so that the first cylinder gradually extends out of the second cylinder, the deformation part pushes the sleeve body to move, so that the base moves towards the direction close to the deformation part until the base abuts against the inner wall of the deformation part, causing the deformation part to deform, so that the deformation part changes from a closed-mouth shape to an open-mouth shape, and the cotton swab head extends out of the first cylinder, and the cotton swab head is used to extract the secretion at the vaginal fornix.

[0007] As a preferred technical solution of the present application, the deformation part includes a plurality of deformation sheets, the deformation sheets can be elastically bent, the deformation sheets are connected to the first cylinder body, and the plurality of deformation sheets are distributed around the central axis of the first cylinder body.

[0008] As a preferred technical solution of the present application, the cotton swab head includes a cotton swab head body and a first elastic member, the first elastic member has elasticity, one end of the first elastic member is connected to the cotton swab head body, and the other end is connected to the base.

[0009] As a preferred technical solution of the present application, a rubber pad is arranged on the deformation sheet, the rubber pad has elasticity, and when the deformation part is in the initial state, a plurality of the rubber pads squeeze a part of the sleeve body located at the closed-mouth part of the deformation part.

[0010] As a preferred technical solution of the present application, the deformation part further includes a plurality of second elastic members. The second elastic members are elastic. The second elastic members are arranged on the deformation piece. The second elastic members can deform along their own length directions. The length directions of the second elastic members are the same as the length direction of the first cylinder. When the deformation part pushes against the sleeve body to move, the deformation part abuts against the sleeve body through the second elastic members, and the second elastic members are compressed along their own length directions.

[0011] As a preferred technical solution of the present application, the second elastic member includes a plurality of sub-rods and an elastic second spring. The second spring is elastic.

[0014] As a preferred technical solution of the present application, the sampler further includes a limit ring. The limit ring is threadedly connected to the outer wall of the second cylinder. When the limit ring is rotated relative to the second cylinder, the limit ring moves relative to the second cylinder along the length direction of the second cylinder. The limit ring is used to contact the vulva to limit the length of the sampler extending into the vagina.

[0015] The present invention also provides a storage device, including the vaginal secretion sampler as described above, and further including a storage box and a box cover. A partition is arranged in the storage box. The partition divides the space in the storage box into a first chamber and a second chamber. The storage box is used to place the sampler in the second state, so that the cotton swab head is placed in the first chamber, and the part of the sampler other than the cotton swab head is placed in the second chamber. The box cover is detachably matched with the storage box. When the box cover covers the storage box, the first chamber is a closed chamber structure.

[0016] Compared with the prior art, the beneficial effects of the present invention: 1. In the solution of this application, by providing a sleeve body, when the sampler is in the first state, the deformation part is in the initial state, and its deformation part is in a closed-mouth shape. At this time, due to the relatively small channel formed by the closed-mouth deformation part, the part of the sleeve body at the channel formed by its deformation part is in a contracted state, so that the cotton swab head is blocked by the sleeve body. In this way, when the sampler in the first state is inserted into the vagina, in the case where the outer wall of the sampler contacts the inner wall of the vagina, due to the protection of the sleeve body and the closed-mouth deformation part, the probability of the cotton swab head contacting vaginal secretions can be reduced; After the sampler in the first state is inserted into the vagina to a certain depth, a medical staff member can hold the second cylinder body with one hand to fix the second cylinder body relative to the human body, and hold the first cylinder body with the other hand, and move the first cylinder body relative to the second cylinder body in the direction towards the deep part of the vagina. At this time, the first cylinder body gradually extends out of the second cylinder body, and its deformation part pushes the sleeve body to move, causing the sleeve body to pull the base to move, so that the base moves towards the direction close to the deformation part. When the base moves on the main body of the first cylinder body, the elasticity of its deformation part can keep it in a closed-mouth shape, so that the cotton swab head is still blocked by the sleeve body, and the probability of the cotton swab head contacting vaginal secretions can be reduced during the process of the first cylinder body being inserted into the vagina; at the same time, during the process of the deformation part pushing the sleeve body to move and gradually inserting into the vagina, since the second cylinder body is fixed relative to the human body at this time, and one end of the sleeve body is connected to the second cylinder body, when the part of the sleeve body contacting the inner wall of the vagina contacts the inner wall of the vagina, the displacement of the part of the sleeve body contacting the inner wall of the vagina relative to the inner wall of the vagina is relatively small. At this time, the sleeve body is outside the first cylinder body, so that during the process of the first cylinder body being inserted into the vagina, the friction received by the inner wall of the vagina can be reduced, and the risk of damage to the inner wall of the vagina can be reduced; As the first cylinder body moves relative to the second cylinder body, after the base moves from the main body of the first cylinder body to the deformation part, the base abuts against the inner wall of the deformation part, causing the deformation part to deform, so that the deformation part changes from a closed-mouth shape to an open-mouth shape. At this time, the cotton swab head can extend out from the open-mouth structure of the deformation part, so that the cotton swab head is located inside the first cylinder body, so as to facilitate the extraction of the secretions at the vaginal fornix by the cotton swab head. At the same time, during the process of the cotton swab head being inserted into the vagina and before reaching the vaginal fornix, the cotton swab head is protected by the sleeve body and the deformation part, and the probability of the cotton swab head sticking to vaginal secretions can be reduced during this insertion process, thereby reducing the probability of the secretions in the shallow part of the vagina in the war zone. In this way, the purity of the secretions in the deep part of the vagina extracted by the cotton swab head is improved, and further the accuracy of subsequent detection of the secretions in the deep part of the vagina is improved; 2. Furthermore, by providing a first elastic member and a cotton swab head body, the cotton swab head body is used to pick up secretions. When the base moves toward the direction close to the deformation portion and the cotton swab head does not extend out of the first cylinder, the base continues to move, causing the cotton swab head body to contact the deformation portion. In the subsequent movement of the base, the first elastic member is gradually compressed until the base abuts against the inner wall of the deformation portion to deform it into an opening shape, and the cotton swab head body extends out of the first cylinder, and the first elastic member gradually recovers its deformation. When the cotton swab head body subsequently contacts the vaginal vault, the first elastic member can reduce the stimulation to the vaginal vault under the elastic action of the first elastic member. The first elastic member can play a buffering role to avoid the situation where the cotton swab head body damages the patient's vagina due to excessive force by the operator. At the same time, the convenience of the deformation portion being transformed from a closed shape to an open shape and the convenience of the cotton swab head extending out of the first cylinder are improved. 3. Further, by providing a second elastic member, the second elastic member includes a plurality of sub-rods and a second elastic spring, so that the second elastic member is in a telescopic structure. When the sampler is in the first state, the force gradually counteracting the deformation portion and the sleeve body is small, so that the second elastic member is in a longer state. When the sampler in this state is inserted into the vagina, because its deformation portion extends out of the second cylinder, the front end of the sampler is the second elastic member, and the second elastic member can play a buffering role, which can reduce the risk of the sampler hitting the vagina during the process of inserting the sampler into the vagina, thereby reducing the risk of vaginal injury; At the same time, when the deformation part pushes the sleeve body to move, the second elastic member of the deformation part pushes against the sleeve body, so that the second elastic member is compressed and deformed, and the second elastic member is shortened, so that after the cotton swab head extends out of the first cylinder, more space is provided for the cotton swab head to extract vaginal secretions; 4. Furthermore, after the cotton swab head extracts vaginal secretions at the vaginal vault, the first barrel is moved relative to the second barrel to reduce the extension of the first barrel beyond the second barrel, thereby reducing the counteraction between the deformation portion and the sleeve, or even eliminating the counteraction between the deformation portion and the sleeve. When there is no counteraction between the deformation portion and the sleeve, the second elastic member can be placed in a state where it is not acted upon by an external force, so that the second elastic member is in an initial state. When the distance a is greater than the distance b, the second elastic member can be distributed around the cotton swab head, and the sleeve can shield the side of the cotton swab head. In this way, in the process of withdrawing the sampler from the patient's vagina, the sleeve can protect the cotton swab head, and can reduce the probability of the cotton swab head being contaminated by secretions in the shallow part of the vagina when the sampler is withdrawn from the vagina, thereby further improving the purity of the secretions extracted from the deep part of the vagina.

[0023] Embodiment 1: This embodiment provides a vaginal secretion sampling device, see Figures 1-6 As shown, the sampler 1 includes a first barrel 2 and a second barrel 3, the second barrel 3 is sleeved on the outside of the first barrel 2, an extraction assembly 4 is arranged in the first barrel 2, the extraction assembly 4 includes a base 5 and a cotton swab head 6, the base 5 is connected to the cotton swab head 6, the base 5 is in contact with the inner wall of the first barrel 2, and the base 5 can move relative to the first barrel 2 along the length direction of the first barrel 2; the first barrel 2 includes a first barrel body 7 and a deformation part 8, the deformation part 8 is located at the end of the first barrel 2 for extending into the vagina, the deformation part 8 is elastic, and the deformation part 8 has an initial state. When the deformation part 8 is in the initial state, the deformation part 8 is in a closed shape; The sampler 1 further comprises a sleeve 9, which is a cylindrical membrane structure. The sleeve 9 is folded from the first cylinder 2 through the deformation portion 8 and extends to the second cylinder 3, so that one end of the sleeve 9 is connected to the second cylinder 3, and the other end is connected to the extraction component 4; The sampler 1 has a first state and a second state. When the sampler 1 is in the first state, the base 5 contacts the inner wall of the first cylinder body 7, the deformation part 8 is in an initial state, and the cotton swab head 6 is blocked by the sleeve 9. During the process of the sampler 1 changing from the first state to the second state, the first cylinder 2 moves relative to the second cylinder 3, causing the first cylinder 2 to gradually extend out of the second cylinder 3. The deformation part 8 pushes against the sleeve 9 to move, causing the base 5 to move towards the direction close to the deformation part 8 until the base 5 abuts against the inner wall of the deformation part 8, deforming the deformation part 8, so that the deformation part 8 changes from a closed-mouth shape to an open-mouth shape, and the cotton swab head 6 extends out of the first cylinder 2. The cotton swab head 6 is used to extract the secretions at the vaginal fornix.

[0024] In the present application, by providing the sleeve 9, when the sampler 1 is in the first state, the deformation part 8 is in an initial state, and the deformation part 8 is in a closed-mouth shape. At this time, due to the relatively small channel formed by the closed-mouth deformation part 8, the part of the sleeve 9 at the channel formed by the deformation part 8 is in a contracted state, so that the cotton swab head 6 is blocked by the sleeve 9. In this way, during the process of inserting the sampler 1 in the first state into the vagina, when the outer wall of the sampler 1 contacts the inner wall of the vagina, due to the protection of the sleeve 9 and the closed-mouth deformation part 8, the probability of the cotton swab head 6 contacting the vaginal secretions can be reduced. After the sampler 1 in the first state is inserted into the vagina to a certain depth, the medical staff can hold the second cylinder 3 with one hand to fix the second cylinder 3 relative to the human body, and hold the first cylinder 2 with the other hand, and move the first cylinder 2 relative to the second cylinder 3 towards the direction deep into the vagina. At this time, the first cylinder 2 gradually extends out of the second cylinder 3. The deformation part 8 pushes against the sleeve 9 to move, causing the sleeve 9 to pull the base 5 to move, and the base 5 to move towards the direction close to the deformation part 8. When the base 5 moves on the first cylinder body 7, the elasticity of the deformation part 8 enables it to maintain a closed-mouth shape, so that the cotton swab head 6 is still blocked by the sleeve 9, and the probability of the cotton swab head 6 contacting the vaginal secretions can be reduced during the process of the first cylinder 2 being inserted into the vagina. At the same time, during the process of the deformation part 8 pushing against the sleeve 9 to move and gradually inserting into the vagina, at this time, since the second cylinder 3 is fixed relative to the human body and one end of the sleeve 9 is connected to the second cylinder 3, when the inner wall of the vagina contacts the sleeve 9, the displacement of the part of the sleeve 9 in contact with the inner wall of the vagina relative to the inner wall of the vagina is relatively small. At this time, the sleeve 9 is on the outside of the first cylinder 2, so that during the process of the first cylinder 2 being inserted into the vagina, the friction received by the inner wall of the vagina can be reduced, and the risk of damage to the inner wall of the vagina can be reduced. As the first cylinder body 2 moves relative to the second cylinder body 3, after the base 5 moves from the first cylinder body main body 7 to the deformation part 8, the base 5 abuts against the inner wall of the deformation part 8, deforming the deformation part 8, so that the deformation part 8 changes from a closed-mouth shape to an open-mouth shape. At this time, the cotton swab head 6 can extend out from the open-mouth structure of the deformation part 8, so that the cotton swab head 6 is located in the first cylinder body 2, so as to extract the secretions at the vaginal fornix by the cotton swab head 6, providing convenience for extracting the secretions at the vaginal fornix. At the same time, during the process of the cotton swab head 6 extending into the vagina and not reaching the vaginal fornix, the cotton swab head 6 is protected by the sleeve body 9 and the deformation part 8, and the probability of the cotton swab head 6 sticking to the vaginal secretions can be reduced during this extension process, thereby reducing the probability of the secretions in the shallow part of the vagina in the war zone. In this way, the purity of the secretions in the deep part of the vagina extracted by the cotton swab head 6 is improved, and further the accuracy of subsequent detection of the secretions in the deep part of the vagina is improved; And in this application, before inserting the sampler 1 into the patient's vagina, the depth of the patient's vagina can be measured first, and then the sampler 1 in the first state is inserted into the patient's vagina. The length of the second cylinder body 3 extending into the vagina can meet the requirement that after the sampler 1 is switched from the first state to the second state, the position of the cotton swab head 6 extending out of the first cylinder body 2 is located at or close to the vaginal fornix; In this application, when the sampler 1 is in the second state, the cotton swab head 6 extends out of the first cylinder body 2.

[0025] As a preferred embodiment, on the basis of the above method, further, the deformation part 8 includes a plurality of deformation pieces 10, the deformation pieces 10 can be elastically bent, the deformation pieces 10 are connected to the first cylinder body main body 7, and the plurality of deformation pieces 10 are distributed around the central axis of the first cylinder body main body 7.

[0026] Furthermore, through more than a plurality of deformation pieces 10, the deformation pieces 10 can be elastically bent. When the deformation part 8 is in the initial state, a plurality of deformation parts 8 cooperate to form a closed-mouth structure, so that the deformation part 8 is in a closed-mouth shape. When the base 5 moves in the direction close to the deformation part 8 and the base 5 abuts against the inner wall of the deformation part 8, the base 5 abuts against the deformation pieces 10, so that under the pushing action of the base 5, the deformation pieces 10 are bent and deformed, and the deformation pieces 10 bend in the direction away from the central axis of the first cylinder body 2, so that a plurality of deformation parts 8 cooperate to form an open-mouth structure, so that the deformation part 8 is in an open-mouth shape, and further the cotton swab head 6 extends out from the open-mouth structure, so that the cotton swab head 6 can extract the secretions at the vaginal fornix after extending out of the first cylinder body 2.

[0027] As a preferred embodiment, on the basis of the above-described manner, further, the cotton swab head 6 includes a cotton swab head body 11 and a first elastic member 12. The first elastic member 12 has elasticity. One end of the first elastic member 12 is connected to the cotton swab head body 11, and the other end is connected to the base 5.

[0028] Further, by providing the first elastic member 12 and the cotton swab head body 11, the cotton swab head body 11 is used for picking up secretions. During the process that the base 5 moves towards the deformation part 8 and the cotton swab head 6 does not extend out of the first cylinder 2, as the base 5 continuously moves, the cotton swab head body 11 will contact the deformation part 8. During the subsequent movement of the base 5, the first elastic member 12 will be gradually compressed until the base 5 abuts against the inner wall of the deformation part 8 and deforms it into an open shape, at which time the cotton swab head body 11 extends out of the first cylinder 2, and the first elastic member 12 gradually recovers its deformation. When the cotton swab head body 11 contacts the vaginal fornix subsequently, under the elastic action of the first elastic member 12, the stimulation received by the vaginal fornix can be reduced. The first elastic member 12 can play a buffering role to avoid the situation that the cotton swab head body 11 damages the patient's vagina due to excessive force applied by the operator; at the same time, the convenience of the deformation part 8 changing from a closed shape to an open shape is improved, and the convenience of the cotton swab head 6 extending out of the first cylinder 2 is improved. Specifically, the first elastic member 12 can be a spring structure.

[0029] As a preferred embodiment, on the basis of the above-described manner, further, a rubber pad 13 is provided on the deformation piece 10. The rubber pad 13 has elasticity. When the deformation part 8 is in the initial state, several of the rubber pads 13 squeeze a part of the sleeve 9 located at the closed end of the deformation part 8.

[0030] Further, by providing the rubber pad 13 on the deformation piece 10, when the deformation part 8 is in the initial state, several rubber pads 13 squeeze a part of the sleeve 9 located at the closed end of the deformation part 8, so that when the cotton swab head 6 does not extend out of the first cylinder 2, the probability of contact between the vaginal secretion and the cotton swab head 6 is further reduced, and further the probability of contact between the secretion in the shallow layer of the vagina and the cotton swab head 6 is reduced; and after the rubber pad 13 is provided on the deformation piece 10, when the deformation part 8 pushes against the sleeve 9, the sleeve 9 can still be pulled out of the first cylinder 2, and at the same time, when the deformation part 8 changes from a closed shape to an open shape, it can still ensure that the cotton swab head 6 extends out of the first cylinder 2.

[0031] Embodiment 2: On the basis of the technical solution of Embodiment 1, further, refer to Figure 1 、 Figure 2 and Figures 4-6As shown, the deformation part 8 further includes a number of second elastic members 14. The second elastic members 14 have elasticity. The second elastic members 14 are arranged on the deformation sheet 10. The second elastic members 14 can deform along their own length directions. The length directions of the second elastic members 14 are the same as the length direction of the first cylinder 2. When the deformation part 8 pushes against the sleeve body 9 to move, the deformation part 8 abuts against the sleeve body 9 through the second elastic members 14, and the second elastic members 14 are compressed along their own length directions.

[0032] As a preferred embodiment, on the basis of the above manner, further, the second elastic member 14 includes a number of sub-rods 15 and an elastic second spring 16. The second spring 16 has elasticity. Adjacent sub-rods 15 are sleeved with each other. The sub-rods 15 can move relative to adjacent sub-rods 15 along the length directions of the sub-rods 15. One end of the second spring 16 is connected to the sub-rod 15 at the head end of a number of sub-rods 15, and the other end is connected to the sub-rod 15 at the tail end of a number of sub-rods 15.

[0033] As a preferred embodiment, on the basis of the above manner, further, when the sampler 1 is in the first state, the deformation part 8 extends out of the second cylinder 3.

[0034] Further, by setting the second elastic member 14 to include a number of sub-rods 15 and an elastic second spring 16, the second elastic member 14 has a telescopic structure. When the sampler 1 is in the first state, the acting force for the deformation part 8 to gradually abut against the sleeve body 9 can be smaller, so that the second elastic member 14 is in a longer state. During the process of the sampler 1 in this state extending into the vagina, since the deformation part 8 extends out of the second cylinder 3, the front end of the sampler 1 is the second elastic member 14, and the second elastic member 14 can play a buffering role, which can reduce the risk of the sampler 1 injuring the vagina during the process of extending into the vagina, and further reduce the risk of vaginal injury; At the same time, during the process of the deformation part 8 pushing against the sleeve body 9 to move, the second elastic member 14 on the deformation part 8 abuts against the sleeve body 9, so that the second elastic member 14 is compressed and deformed, and the second elastic member 14 is shortened, so as to provide more space for the cotton swab head 6 to extract vaginal secretions after the cotton swab head 6 extends out of the first cylinder 2.

[0035] As a preferred embodiment, on the basis of the above-described manner, further, when the second elastic member 14 is not subjected to an external force, the second elastic member 14 is in an initial state; when the cotton swab head 6 extends out of the first cylinder 2 and the second elastic member 14 is in the initial state, the distance between the region of the second elastic member 14 farthest from the second cylinder 3 and the second cylinder 3 is a, and the distance between the region of the cotton swab head 6 farthest from the second cylinder 3 and the second cylinder 3 is b, and a > b.

[0036] Further, after the cotton swab head 6 extracts the vaginal secretion at the vaginal fornix, by moving the first cylinder 2 relative to the second cylinder 3, the elongation amount of the first cylinder 2 extending out of the second cylinder 3 is reduced, so as to reduce the abutting effect between the deformation part 8 and the sleeve 9, and even release the abutting effect between the deformation part 8 and the sleeve 9. When there is no abutting effect between the deformation part 8 and the sleeve 9, the second elastic member 14 can be in a state where it is not subjected to an external force, so that the second elastic member 14 is in the initial state. When the distance a is greater than the distance b, the second elastic member 14 can be distributed around the cotton swab head 6, and the sleeve 9 can shield the side surface of the cotton swab head 6. Thus, during the process of withdrawing the sampler 1 from the patient's vagina, the sleeve 9 can protect the cotton swab head 6, and can reduce the probability of the cotton swab head 6 being contaminated by the secretion in the shallow part of the vagina when the sampler 1 is withdrawn from the vagina, thereby further improving the purity of the secreted matter deep in the vagina extracted.

[0037] As a preferred embodiment, on the basis of the above-described manner, further, the sampler 1 further includes a limit ring 17, the limit ring 17 is threadedly connected to the outer wall of the second cylinder 3, and when the limit ring 17 is rotated relative to the second cylinder 3, the limit ring 17 moves relative to the second cylinder 3 along the length direction of the second cylinder 3, and the limit ring 17 is used to contact the vulva to limit the length of the sampler 1 extending into the vagina.

[0038] Further, by providing the limit ring 17, the limit ring 17 is used to contact the vulva, and at the same time, by rotating the limit ring 17 relative to the second cylinder 3, the position of the limit ring 17 in the length direction of the second cylinder 3 is adjusted, thereby improving the convenience of limiting the length of the sampler 1 extending into the vagina.

[0039] Example 3: A storage device provided in this example, see Figure 7 and Figure 8As shown, it includes the vaginal secretion sampling device as described above, and also includes a storage box 18 and a box cover 19. A partition member 20 is provided in the storage box 18. The partition member 20 divides the space in the storage box 18 into a first chamber 21 and a second chamber 22. The storage box 18 is used to place the sampler 1 in the second state, with the cotton swab head 6 placed in the first chamber 21 and the part of the sampler 1 other than the cotton swab head 6 placed in the second chamber 22. The box cover 19 is detachably matched with the storage box 18. When the box cover 19 is covered on the storage box 18, the first chamber 21 is a closed chamber structure.

[0040] In this application, its storage device includes the vaginal secretion sampling device and the storage box 18. After the sampler 1 extracts the secretion at the vaginal fornix and the sampler 1 is taken out of the patient's vagina, the first cylinder 2 can be moved relative to the second cylinder 3 again to release the sleeve 9 from blocking the side of the cotton swab head 6. Then, the cotton swab head 6 is placed in the first chamber 21, and the part of the sampler 1 other than the cotton swab head 6 is placed in the second chamber 22. At the same time, a base 23 is provided on the cotton swab head 6, a groove 24 is provided on the partition member 20, and half of the base 23 is stuck in the groove 24. A secondary partition member 25 is adapted on the box cover 19, and a secondary groove 26 is provided on the secondary partition member 25. After the box cover 19 is buckled on the storage box 18, the other half of the base 23 is stuck in the secondary groove 26, so that the partition member 20 and the secondary partition member 25 squeeze the base 23, thereby making the cotton swab head 6 extend into the first chamber 21 and making the first chamber 21 in a sealed state. The specific way of buckling the box cover 19 on the storage box 18 is prior art and will not be elaborated here.
