[0022] The present invention provides a vaginal sampling and extraction device, which is designed to improve the efficiency and accuracy of vaginal secretion collection and provide more reliable support for the diagnosis of gynecological diseases. The following is a detailed description of a specific embodiment of the present invention.
[0023] Reference Figures 1 to 6 As shown, the vaginal sampling and extraction device of the present invention mainly includes two parts: a collection component and an extraction component.
[0024] The collection component is used to collect secretion samples from the vagina, and it includes a main body, a rod body 1 and a mounting part 4. The main body is the main working part of the collection component, including a sampling part 2 and a storage part 3. The sampling part 2 is used to absorb small solid secretions on the vaginal wall, while the storage part 3 is used to absorb vaginal secretions. The sampling part 2 and the storage part 3 are connected together to form the main body; the sampling part 2 is arranged between the mounting part 4 and the storage part 3, and is connected to the rod body 1, and the sampling part 2 is arranged in the mounting part 4. In a specific embodiment of the present invention, the sampling part 2 includes two parts, the front end part is a swab part 21 that contacts the inner wall of the vagina, and the rear end part is a pressing part 22 for installation, the pressing part 22 is located between the mounting part 4 and the storage part 3, and the swab head is threadedly connected to the rod body 1.
[0025] The specific design of the sampling piece 2 can be adjusted according to actual needs. In the specific embodiment of the present invention, the sampling piece 2 is made of a hard fiber head, which has good adsorption and durability. The design of the hard fiber head enables it to firmly adsorb small solid secretions on the vaginal wall without causing damage to the vaginal wall; the storage piece 3 is made of absorbent materials such as fiber cotton, which can effectively absorb and store vaginal secretions. Fiber cotton has good water absorption and air permeability, which can ensure the adequacy and integrity of the sample.
[0026] The rod body 1 is a bridge connecting the sampling part 2 and the storage part 3 with the mounting part 4. It is arranged in the mounting part 4 and is used to hold and operate the collection component. The length and diameter of the rod body 1 can be adjusted according to actual needs to ensure that the operator can hold and operate it comfortably. In a specific embodiment of the present invention, the total length of the collection component is 15 cm, the vaginal part that can be inserted is 13.5 cm, and the diameter of the sampling part 2 is 1.2 cm. The rod body 1 is made of corrosion-resistant materials such as stainless steel to ensure that it will not be corroded and contaminated during use. At the same time, the outer wall of the rod body 1 is connected to the storage part 3 to ensure that the storage part 3 can be firmly fixed on the rod body 1.
[0027] The mounting member 4 is a fixed part of the collection component, which is used to connect the sampling member 2 and the storage member 3 to the rod body 1. It also has the function of protecting the sampling member 2 and the storage member 3 to prevent them from being damaged during the collection process. In a specific embodiment of the present invention, the mounting member 4 is made of lightweight materials such as plastic to reduce the weight of the entire collection component. Specifically, an elastic push rod 41 is provided between the mounting member 4 and the sampling member 2, and telescopic rods 42 are connected to both ends of the elastic push rod 41. The telescopic rod 42 is connected to the inner wall of the mounting member 4. By providing the elastic push rod 41 and the telescopic rod 42, the sampling member 2 can be fixed in the mounting member 4 by using the elastic push rod 41, which is convenient for installation and disassembly. A boss 23 is formed between the pressing part 22 and the swab part 21. The mounting member 4 is sleeved on the rod body 1 during installation and abuts against the boss 23. At this time, the storage member 3 also abuts against the boss 23, which is convenient for the storage member 3 to absorb the vaginal secretions in the sampling member 2.
[0028] The inner circular array of the pressing part 22 has a plurality of accommodating cavities 221, and an extrusion assembly is arranged in the accommodating cavity 221, and the extrusion assembly includes a fixed block 222, an elastic member 224 and a top block 223. The fixed block 222 protrudes from the pressing part 22 and abuts against the mounting member 4, and the top block 223 protrudes from the pressing part 22 and abuts against the storage member 3, and the elastic member 224 is arranged between the fixed block 222 and the top block 223. When the operator stirs the collection assembly in the vagina, the swab part 21 is subjected to force, so that the fixed block 222 is subjected to lateral pressure, and the fixed block 222 pushes the top block 223 through the elastic member 224, so that the top block 223 protrudes inward, squeezes the storage member 3, and increases the speed at which the vaginal secretions enter the fiber head. During repeated squeezing, the storage member 3 will also absorb a large amount of vaginal secretions. In the embodiment of the present invention, a pair of elastic members 224 are disposed in each accommodating cavity 221, one end of the elastic member 224 is clamped to the inner wall of the accommodating cavity 221, and the other end is slidably disposed on the top block 223, the elastic member 224 is bent, and the bent portion of the fixed block 222 is connected to the elastic member 224. When the elastic member 224 is subjected to force, the elastic member 224 is deformed, and one end of the two elastic members 224 slides toward each other on the top block 223, thereby applying force to the top block 223.
[0029] The extraction assembly is used to extract and separate the collected vaginal secretion samples, and it includes an extraction bottle body 5, a bottle cap 6 and a bottle base 7. The bottle cap 6 and the bottle base are detachably connected to the extraction bottle body 5. In the embodiment of the present invention, the bottle cap 6 and the bottle base 7 are both threadedly connected to the extraction bottle body 5. The extraction bottle body 5 is the main part of the extraction assembly, which is used to contain the extraction liquid and the sample. It is made of transparent materials such as glass or plastic so that the operator can clearly observe the extraction process. In a specific embodiment of the present invention, the shape and size of the extraction bottle body 5 can be adjusted according to actual needs. At the same time, its inner wall is specially treated to ensure that the extraction liquid will not corrode and pollute it. The bottle cap 6 is used to seal the extraction bottle body 5 to prevent sample contamination and volatilization. One side of the bottle cap 6 is provided with an extrusion port for allowing the storage member 3 with the rod body 1 to pass through. The bottle cap 6 of the present invention has two states when installed. The first state is partially installed on the extraction bottle body 5. At this time, the extrusion port is outside the extraction bottle body 5, which is convenient for the storage member 3 to extend into. The second state is completely installed on the extraction bottle body 5. At this time, the extrusion port is inside the extraction bottle body 5, and the extraction bottle body 5 is in a sealed state. At least one group of extrusion rollers 8 are arranged in the bottle cap 6 to squeeze out the vaginal secretions absorbed in the storage member 3. In a specific embodiment of the present invention, the bottle cap 6 is made of light materials such as plastic. The number and position of the extrusion rollers 8 can be adjusted according to actual needs to ensure that the sample in the storage member 3 can be fully squeezed out. In addition, the bottle cap 6 is also provided with a liquid outlet 61, and a rotary piston valve 62 is installed on the liquid outlet 61. The liquid outlet 61 is used to discharge the sample solution after extraction, and the rotary piston valve 62 is used to control the switch of the liquid outlet 61. Through the rotary piston valve 62, the operator can conveniently control the discharge speed of the sample solution to ensure the smooth progress of the extraction process. The bottle base 7 is used to install the sampling member 2 and fix the extraction bottle body 5. The bottle base 7 is provided with a positioning groove for fitting with the pressing portion 22 of the sampling member 2 to ensure that the sampling member 2 can be stably installed on the bottle base 7.
[0030] The operation method of the vaginal sampling and extraction device of the present invention is as follows: S1. The operator first holds the rod and inserts the main body of the collection component into the vagina. During the insertion process, the operator needs to pay attention to maintaining the stability of the collection component to prevent it from being damaged or contaminated; S2. When the main body is inserted into the sampling position, the operator uses the main body to stir the vagina for sampling. The intensity and frequency of stirring can be adjusted according to actual needs to ensure that small solid secretions and vaginal secretions on the vaginal wall can be fully collected; S3. After completing the sampling, the operator disassembles the collection assembly into three parts: the installation part, the sampling part, and the rod body with the storage part. During the disassembly process, the operator needs to pay attention to keeping each part clean and intact to avoid contamination or loss of the sample; S4. Install the disassembled sampling piece on the bottle base. During the installation process, the operator needs to make sure that the pressing portion of the sampling piece fits into the positioning groove of the bottle base to ensure that the sampling piece can be stably installed on the bottle base. S5. Install the bottle base onto the extraction bottle body, and pour the extraction liquid into the extraction bottle body to immerse the sampling piece.
[0031] S6, install the bottle cap part onto the extraction bottle body, so that the storage part with the rod body can penetrate into the bottle cap through the extrusion port. Then use the extrusion roller to squeeze out the vaginal secretions absorbed by the storage part; after the extrusion is completed, install the bottle cap completely onto the extraction bottle body, so that the extraction bottle body is in a sealed state; S7. Place the extraction tube body in a vortex oscillator for oscillation extraction; the frequency and time of oscillation can be adjusted according to actual needs. After the oscillation is completed, place the extraction tube body in a centrifuge for centrifugal separation. The speed and time of centrifugation can also be adjusted according to actual needs. After the centrifugation is completed, let the extraction tube body stand for a period of time to allow the sample solution to separate; finally, open the rotary piston valve on the bottle cap to discharge the extracted sample solution for subsequent analysis.
[0032] In summary, the vaginal sampling and extraction device proposed in the present invention has significant beneficial effects and application prospects. By implementing the present invention, we can improve the efficiency and accuracy of vaginal secretion collection and provide more reliable support for the diagnosis of gynecological diseases. At the same time, it also provides new ideas and methods for other medical research fields that require vaginal secretion analysis.
