A reproductive center with vaginal secretion sampling device

Abstract

This utility model relates to the field of secretion sampling technology, specifically disclosing a vaginal secretion sampling device for reproductive centers. It includes a collection tube with a sampling component fixedly connected to its exterior. The sampling component is located inside the collection tube and samples vaginal secretions from the patient. An aspiration component is located inside a storage tube and retrieves the stored secretion sample. In use, the semi-circular sampling cap, combined with a swab ring, is brought into contact with the vaginal wall by gently pulling the handle. Secretions are actively collected through a scraping action. Compared to the passive adsorption of traditional swabs relying on capillary action, this method provides more thorough collection of samples with high viscosity or tight adhesion, thus reducing detection errors caused by insufficient sample. The swab ring completes sampling simultaneously through scraping and adsorption, reducing the time the instrument remains in the vagina.

Description

Technical Field

[0001] This utility model relates to the field of secretion sampling technology, specifically a vaginal secretion sampling device for reproductive centers. Background Technology

[0002] The vaginal secretion sampling device used in reproductive centers is a tool specifically designed to collect vaginal secretions such as leukorrhea and cervical mucus from women. It is mainly used to detect vaginal microecology, pathogens (such as bacteria, fungi, mycoplasma, etc.), hormone levels, or to assess reproductive health status, for the diagnosis and treatment of infertility and assisted reproductive technology.

[0003] In existing technologies, when sampling vaginal secretions, a vaginal speculum is first used to gently and slowly open the vagina to fully expose the target areas such as the cervix and vaginal walls. Then, a sterilized sampling swab is carefully inserted into the vagina four to five centimeters. According to standard operating procedures, the swab needs to be rotated one to two times in the vaginal wall or cervical canal, and then held still for 10 to 15 seconds to allow the swab fibers to absorb secretions through physical contact. The swab's absorption process relies entirely on the natural capillary action and surface tension of the fiber material, making it difficult to actively absorb secretions. For highly viscous secretions or tightly adhered samples, it is often difficult to collect sufficient samples, which may lead to insufficient sample volume or compositional deviations, affecting the accuracy of subsequent tests. At the same time, the swab's prolonged stay in the vagina can easily cause discomfort to patients, especially for sensitive individuals such as those with vaginismus or cervicitis, where discomfort can be significantly aggravated. Therefore, we propose a vaginal secretion sampling device for reproductive centers. Utility Model Content

[0004] The purpose of this invention is to provide a vaginal secretion sampling device for reproductive centers to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vaginal secretion sampling device for reproductive centers, comprising a collection tube, a sampling component fixedly connected to the outside of the collection tube, and further comprising:

[0006] The sampling component is located inside the collection tube and is used to sample vaginal secretions from the patient.

[0007] The suction component is located inside the storage cylinder and is used to extract secretion samples stored inside the storage cylinder.

[0008] The sampling component includes a scraping sleeve, a sliding cover inside the collection tube, a fitting groove on the outside of the fitting cover, a connecting rod fixedly connected to the bottom of the fitting cover, a semi-circular sampling cover fixedly connected to the bottom of the connecting rod, and a swab ring fixedly connected to the outside of the semi-circular sampling cover.

[0009] The suction component includes a sealing ring, and a rubber cap is installed inside the suction component. A dropper is fixedly connected to the bottom of the rubber cap.

[0010] The connecting rod has a display ring 1 fixedly connected to its bottom outer end and a display ring 2 fixedly connected to its top outer end.

[0011] The semi-circular sampling cap is made of soft silicone and is slidably connected to the inside of the scraping sleeve.

[0012] The swab ring is in contact with the outside of the scraping sleeve.

[0013] The outer surface of the cover is fixedly connected with a silicone block, and the top of the cover is fixedly connected with a handle.

[0014] This utility model has at least the following beneficial effects:

[0015] When using this invention, the semi-circular sampling cap is used in conjunction with the swab ring. By gently pulling the handle, the swab ring comes into contact with the vaginal wall and actively collects secretions through scraping. Compared with the passive adsorption of traditional swabs that rely on capillary action, this method can collect samples with high viscosity or tight adhesion more fully, thereby reducing detection deviations caused by insufficient samples.

[0016] The swab ring completes sampling simultaneously through scraping and adsorption, eliminating the need for the 10 to 15 seconds of stillness required by traditional swabs. The entire sampling process is shortened to 3 to 5 seconds, reducing the time the instrument remains in the vagina. This is especially beneficial for patients with vaginismus or cervicitis, alleviating discomfort and reducing pain or tension caused by the procedure. The semi-circular sampling cap and swab ring feature rounded edges to minimize frictional damage to the vaginal mucosa. The silicone block and fitting groove work together to ensure a sealed collection tube during sampling, preventing leakage and contamination of secretions.

[0017] By using display ring one and display ring two, the sampling depth can be clearly marked, ensuring that samples are taken from the target area such as the middle or deep part of the vagina, which meets the requirements of the test for samples from specific sites. This avoids the sample composition deviation caused by the traditional method of judging the location based on experience, and improves the reliability of the test results.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figures 1 to 6 This utility model provides a technical solution: a vaginal secretion sampling device for reproductive centers, including a collection tube 1, a sampling component 2 fixedly connected to the outside of the collection tube 1, and further including:

[0028] Sampling component 2 is installed inside the collection tube 1, and the sampling component 2 is used to sample the vaginal secretions of the patient.

[0029] The suction component 3 is located inside the storage cylinder 101. The suction component 3 is used to extract the secretion sample stored inside the storage cylinder 101. The collection cylinder 1 temporarily stores the freshly sampled secretion. The storage cylinder 101 preserves the sample. Before sampling, the semi-circular sampling cap 207 is inside the scraping sleeve 201. The swab ring 208 fits against the inner wall of the scraping sleeve 201 to avoid contamination by impurities. The silicone block 204 cooperates with the fitting groove 203 to ensure the sealing of the collection cylinder 1.

[0030] The sampling assembly 2 includes a scraping sleeve 201, an adhesive cover 202 slidably connected inside the collection cylinder 1, an adhesive groove 203 on the outside of the adhesive cover 202, a connecting rod 206 fixedly connected to the bottom of the adhesive cover 202, a semi-circular sampling cover 207 fixedly connected to the bottom of the connecting rod 206, and a swab ring 208 fixedly connected to the outside of the semi-circular sampling cover 207. The semi-circular sampling cover 207 is made of soft silicone and is slidably connected to the inside of the scraping sleeve 201. The swab ring 208 is in contact with the outside of the scraping sleeve 201. During sampling, the vagina is opened with a vaginal speculum, and the semi-circular sampling cover 207 is inserted into the vagina by holding the handle 205. The depth is observed through the display ring 1 4 and the display ring 2 401 to control the sampling position. The handle 205 is pulled lightly to make the swab ring 208 contact the vaginal wall. Through adsorption and scraping, the secretions are attached to the surface of the semi-circular sampling cover 207 and the swab ring 208.

[0031] The suction assembly 3 includes a sealing ring 301 and a rubber cap 302 inside the suction assembly 3. A dropper 303 is fixedly connected to the bottom of the rubber cap 302. Using the suction assembly 3, the sealing ring 301 ensures a tight seal. The rubber cap 302 is squeezed to expel air. The dropper 303 is inserted into the storage cylinder 101. The rubber cap 302 is released, and the sample is drawn into the dropper 303 by the air pressure difference, thus achieving accurate sample retrieval.

[0032] A display ring 4 is fixedly connected to the bottom of the connecting rod 206, and a display ring 401 is fixedly connected to the top of the connecting rod 206. The display ring 4 is fixedly connected to the bottom of the connecting rod 206 at a distance of 4 cm. By observing the depth of its entry into the vagina, the sampling position is indicated as the middle of the vagina, ensuring that the sampling site meets the testing requirements.

[0033] A silicone block 204 is fixedly connected to the outside of the fitting cover 202, and a handle 205 is fixedly connected to the top of the fitting cover 202; the silicone block 204 is fixedly connected to the outside of the fitting cover 202 and cooperates with the fitting groove 203 to enhance the sealing of the collection cylinder 1.

[0034] The working principle of this utility model is as follows: the collection cylinder 1 and the storage cylinder 101 constitute the main body for collecting and storing secretions. The collection cylinder 1 is used to temporarily store the secretions that have just been sampled, and the storage cylinder 101 is used to store the sample. The handle 205 of the sampling component 2 is convenient for medical staff to hold and operate. The connecting rod 206 connects the handle 205 and the semi-circular sampling cover 207. Before sampling, the semi-circular sampling cover 207 is inside the scraping sleeve 201, and the swab ring 208 fits against the inner wall of the scraping sleeve 201 to ensure that there is no impurity contamination before sampling. The silicone block 204 is fixed to the outside of the fitting cover 202 and cooperates with the fitting groove 203 of the collection cylinder 1 to ensure the sealing of the collection cylinder 1 during sampling.

[0035] During sampling, the vagina is first gently and slowly opened with a vaginal speculum. Then, the semi-circular sampling cover 207 is inserted into the vagina, and the handle 205 is gently pulled to make the swab ring 208 contact the vaginal wall. Through the adsorption and scraping action of the swab ring 208, the vaginal secretions are attached to the surface of the semi-circular sampling cover 207 and the swab ring 208 to complete the sampling.

[0036] After sampling is completed, the sampling component 2 is slowly pulled out and then inserted into the collection tube 1. When the semi-circular sampling cover 207 passes the scraping sleeve 201, the inner wall of the scraping sleeve 201 comes into close contact with the swab ring 208, scraping off the secretions attached to the semi-circular sampling cover 207 and the swab ring 208. The scraped secretions fall into the collection tube 1, thus collecting the sample.

[0037] If the sample in the storage cylinder 101 needs to be tested, the suction component 3 is operated. The sealing ring 301 ensures the sealing of the storage cylinder 101 during suction. After squeezing the cap 302 to expel the air, since the storage cylinder 101 and the collection cylinder 1 are interconnected, it is only necessary to insert the dropper 303 into the storage cylinder 101, loosen the cap 302, and use the air pressure difference to draw the secretion sample into the dropper 303, so as to achieve accurate sample extraction and facilitate subsequent testing and analysis.

[0038] Example 2

[0039] Please see Figures 3 to 4 In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the display ring 4 on the outside of the connecting rod 206 is located at 4 cm and the display ring 401 is located at 6 cm. By observing the depth of the display rings entering the vagina, the sampling position can be precisely controlled. For example, 4 cm corresponds to the middle of the vagina and 6 cm corresponds to the deep part of the vagina, ensuring that the sampling site meets the testing requirements.
