Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a vaginal secretion collector. Background Technology

[0002] In gynecological examinations and diagnoses, the collection of vaginal secretions is one of the common examination items. Currently, when patients collect vaginal secretions, a long cotton swab is usually used to collect the secretions, and then the swab is placed into a glass tube containing physiological saline for testing.

[0003] However, existing methods for collecting vaginal secretions have several problems: Current vaginal secretion collectors typically use traditional glass or plastic tubes as sampling tubes, which are fragile, have poor sealing, are complex to operate, and lack adequate aseptic design. This can easily lead to sample leakage, contamination, or cross-infection, resulting in inaccurate sampling results. Furthermore, nurses need to add saline solution to the sampling tubes daily for later use; if the tubes are not used within 24 hours, they must be discarded, which is wasteful and inconvenient. Improper addition of saline solution can also cause contamination. In addition, the sampling process with existing devices is not convenient enough, increasing the workload of medical staff. Therefore, there is an urgent need for a vaginal secretion collector with good sealing, easy operation, and an aseptic design. Utility Model Content

[0004] To address the aforementioned problems, this invention aims to provide a vaginal secretion collector that is easy to operate, has a self-sealing function, and is pre-filled with physiological saline, significantly improving the convenience of sampling operations and the safety of samples.

[0005] The main idea of ​​the technical solution adopted in this utility model is to achieve high efficiency, convenience and safety in the sampling process through the elastic film self-sealing structure, quick sample storage cap and aseptic design.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A vaginal secretion collector includes a sampling tube pre-filled with physiological saline.

[0008] The sampling tube has an elastic film self-sealing structure above the physiological saline, and a detachable tube cap is attached to the top of the sampling tube. A quick sample storage cap is rotatably mounted on the tube cap.

[0009] Furthermore, the above-mentioned solution includes: symmetrically connected trapezoidal holes on the center of the upper and lower surfaces of the self-sealing elastic film structure, which facilitate the passage of the sampling swab. The passage of the sampling swab can achieve a seal with the contact, preventing liquid leakage.

[0010] Further, according to the above scheme: an installation groove is opened in the middle of the tube cap, one end of the installation groove is rotatably connected to the quick sample storage cap, and the other end is provided with a female buckle. A sample storage hole is opened through the center of the tube cap, and a sealing ring is provided on the inner side wall of the tube cap. The sealing ring cooperates with the sampling tube opening.

[0011] Further, the above solution includes: a female buckle that mates with the female buckle on the quick sample storage cover; a sealing element that mates with the sample storage hole in the middle of the quick sample storage cover; a leak-proof membrane sandwiched inside the sealing element; and the leak-proof membrane fitting snugly against the inner ring of the sealing ring.

[0012] Furthermore, according to the above scheme, the sampling tube is an oblique-mouthed tube.

[0013] The beneficial effects of this utility model are:

[0014] 1. Ensure the accuracy of sampling results: By pre-filling physiological saline, the sampling tube is equipped with an elastic film self-sealing structure above the physiological saline. The sealing element is sandwiched with a leak-proof membrane, which fits against the inner ring of the sealing ring, firmly locking the physiological saline in the sampling tube. The cotton swab will immediately self-seal upon insertion, reducing the chance of impurities and bacteria entering, improving the accuracy of the test, and preventing the sampling results from being contaminated. The pre-filled physiological saline sealed tube can be uniformly disinfected and sterilized, extending its service life.

[0015] 2. Improve sampling efficiency: When using, simply open the quick sample storage cap, the sealing element pulls out the leak-proof membrane, tear off the leak-proof membrane, quickly pass the sampling swab through the sample storage hole of the tube cap through the trapezoidal hole, and then close the quick sample storage cap to seal and preserve it. At the same time, the elastic film self-sealing structure has symmetrical trapezoidal holes that are connected in the center of the upper and lower sides, which not only have a guiding function, but also facilitate the passage of the sampling swab.

[0016] 3. Extremely high sealing performance: First, the elastic film self-sealing structure can self-seal after the sampling swab passes through, preventing liquid leakage. Second, the quick sample storage cap is equipped with a sealing element, and the inner wall of the tube cap is also equipped with a sealing ring, which ensures the sealing and safety of the sample and avoids the risk of sample contamination or leakage.

[0017] 4. The slanted nozzle design makes it easier for inspectors to remove the swabs, mix them thoroughly, and improve the accuracy of the test results. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0030] In their practice, the inventors discovered that existing vaginal secretion collectors typically use traditional glass or plastic tubes as sampling tubes. These tubes are fragile, have poor sealing, are complex to operate, and lack adequate aseptic design, which can easily lead to sample leakage, contamination, or cross-infection, resulting in inaccurate sampling results. In addition, nurses need to add saline solution to the sampling tubes daily for later use. If the tubes are not used for more than 24 hours, they must be discarded, which is wasteful and inconvenient. Furthermore, improper addition of saline solution can also lead to contamination. Moreover, the sampling process of existing devices is not convenient enough, increasing the workload of medical staff.

[0031] Based on the above findings, this application proposes a vaginal secretion collector that is easy to operate, has a self-sealing function, and is pre-filled with physiological saline, which significantly improves the convenience of sampling operations and the safety of samples. Example

[0032] See Figures 1-8 This application discloses a vaginal secretion collector, including a sampling tube 1, an elastic film self-sealing structure 2, a tube cap 3, and a quick sample storage cap 4. The sampling tube 1 is pre-filled with 1 ml of physiological saline. The elastic film self-sealing structure 2 is set above the sampling tube 1 relative to the physiological saline. The tube cap 3 is detachably connected to the top of the sampling tube 1. The quick sample storage cap 4 is rotatably set on the tube cap 3, so that the cotton swab can pass through the quick sample storage cap 4 directly through the elastic film self-sealing structure 2.

[0033] Sampling tube 1 is a 10cm long, 1.5cm inner diameter, and 0.2cm wall thickness cylindrical tube with an angled opening. Its size is designed for easy hand-held operation, while its moderate inner diameter can hold sufficient physiological saline and sample. The angle of the opening is between 30° and 45°, ensuring smooth insertion and removal of the swab, minimizing sample residue at the tube opening, and facilitating sample mixing when needed. Sampling tube 1 is made of medical-grade polypropylene (PP) material, giving it good biocompatibility and chemical stability, ensuring durability and safety, and guaranteeing that the sample is not contaminated during collection and storage.

[0034] It is worth noting that the elastic film self-sealing structure 2 is made of medical-grade silicone material, possessing excellent elasticity and sealing properties. Its thickness is 0.5mm, and its diameter is 1.4cm, ensuring a tight fit with the inner diameter of the sampling tube 1. The elastic film self-sealing structure 2 has symmetrically connected trapezoidal circular holes 201 at the center of its upper and lower surfaces. The upper diameter of each trapezoidal circular hole 201 is 2mm, the lower diameter is 4mm, and the height is 1mm. The two trapezoidal circular holes 201 are connected, facilitating the passage of the sampling swab. Simultaneously, after the sampling swab has passed through, it self-closes and seals, preventing leakage of saline solution and external contamination. Furthermore, due to the structural characteristics of the trapezoidal circular holes 201, they provide guidance for the insertion and removal of the swab, facilitating operation by staff.

[0035] Notably, the design of the tube cap 3 facilitates a tight connection with the sampling tube 1. Made of medical-grade polycarbonate (PC) material, the tube cap 3 boasts high strength and transparency, allowing for easy observation of the internal structure of the sampling tube 1. The tube cap 3 has an outer diameter of 1.6 cm and a height of 1.2 cm, and is detachably connected to the sampling tube 1, such as via a threaded connection. A mounting groove 301, 0.8 cm wide and 0.5 cm deep, is formed in the center of the tube cap 3. One end of the mounting groove 301 is rotatably connected to the quick sample storage cap 4, while the other end has a female buckle 303, which connects to the quick sample storage cap 4. A sample storage hole 302 with a diameter of 0.6 cm is formed through the center of the tube cap 3, ensuring smooth passage of the swab. The inner wall of the tube cap 3 is provided with a sealing ring 304 with an outer diameter of 1.6 cm and an inner diameter of 1.4 cm. The sealing ring 304 has an angle between 30° and 45°. The sealing ring 304 fits with the opening of the sampling tube 1 to prevent leakage of physiological saline. The sealing ring 304 is made of medical grade silicone material and has good elasticity and sealing performance.

[0036] Specifically, the rapid sample storage cap 4 is also made of medical-grade polycarbonate (PC) material, which has high strength and transparency. It is 1.5cm long, 0.8cm wide, and 0.3cm thick. One end is rotatably connected to the tube cap 3, and the other end has a female buckle 402. The female buckle 402 cooperates with the female buckle 303, allowing the rapid sample storage cap 4 to be opened quickly. A sealing element 401 is located in the middle of the rapid sample storage cap 4. The sealing element 401 has a diameter of 0.6cm and is made of medical-grade silicone material, which has good elasticity and sealing performance. The sealing element 401 fits tightly with the sample storage hole 302 for a second sealing design, further preventing sample leakage or contamination. Simultaneously, a leak-proof membrane 403 is sandwiched inside the sealing element 401. The leak-proof membrane 403 fits against the inner ring of the sealing ring 304, preventing saline solution from flowing out of the trapezoidal hole 201 and then out of the tube cap 3.

[0037] One usage process of this embodiment is as follows:

[0038] Sampling procedure: After collecting vaginal secretion samples, open the quick sample storage cap 4, and the sealing element 401 pulls the leak-proof membrane 403 out from the sample storage hole 302. Tear off the leak-proof membrane 403, insert the sampling swab into the sample storage hole 302 in the middle of the quick sample storage cap 4, and then enter the physiological saline in the sampling tube 1 through the trapezoidal round hole 201 of the elastic film self-sealing structure 2. Close the quick sample storage cap 4.

[0039] Cleaning procedure: Place sampling tube 1 into a sterile bag and send it to the laboratory for analysis.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
