Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a flexible reproductive tract sampler. Background Art

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items used directly or indirectly on the human body, including the required computer software. Medical devices include medical equipment and medical consumables. The effect is mainly obtained through physical means, not through pharmacology, immunology or metabolism, or although these means are involved, they only play an auxiliary role. The purpose is to diagnose, prevent, monitor, treat or alleviate diseases; diagnose, monitor, treat, alleviate or compensate for injuries; inspect, replace, regulate or support physiological structures or physiological processes; support or maintain life; control pregnancy; provide information for medical or diagnostic purposes by examining samples from the human body. In order to examine the microbial infection status of the female reproductive tract, it is necessary to sample and test the microorganisms of the female reproductive tract. Existing sampling of female reproductive tract microorganisms usually uses disposable medical cotton swabs. After sampling, the cotton swabs are placed in disposable open plastic test tubes and then transported. The disposable cotton swabs and test tubes are not independently sealed. They are transferred by the patient's bare hands, and there is a risk of dropping or misplacing. Whether before sampling or during transportation, the risk of contamination of the sample cannot be guaranteed. If the sample is contaminated, it may affect the test results and interfere with the doctor's diagnosis. For this purpose, the application number is CN202221408272.1, which discloses a female reproductive tract microorganism sampler, including a sampling rod with a brush and a sample protection tube. The upper part of the sampling rod is equipped with a screw cap, which can be moved on the sampling rod. The sampling rod is provided with a scale, which is convenient for doctors to mark according to the patient's vaginal depth before sampling. The sample protection tube is a small tube made of PVC material. The open end of the tube can be connected to the screw cap on the sampling rod by thread. After the sampling is completed, the screw cap can be connected to the sample protection tube, and the screw cap can be tightened to avoid contact with the outside world, which is convenient for taking. The sample protection tube is provided with an identification sticker, and the patient's name and sampling time information can be written on the identification sticker. The sampled sample of the utility model is stored in the closed space of the sample protection tube. The patient will not touch the sampled sample when taking it or transporting it, which avoids secondary contamination during transportation. It has a simple structure and is easy to operate, which can effectively improve the efficiency of female reproductive tract microorganism detection.

[0003] However, the above scheme still has certain defects. The inventors have found through research that the brush used to collect bacteria or cells in the reproductive tract in the above scheme is arranged at the end of the sampling rod. Because there are many wrinkles inside the reproductive tract and it has a certain curvature, and the friction between the brush and the inner wall of the reproductive tract is relatively large compared to the sampling rod, after the sampling rod drives the brush into the patient's reproductive tract, the brush may be pressed against the wrinkles of the inner wall of the reproductive tract, causing the sampling rod to bend and causing discomfort to the patient.

[0004] How to invent a flexible reproductive tract sampler to improve these problems has become an urgent problem to be solved by technicians in this field. Utility Model Content

[0005] In order to make up for the above deficiencies, the utility model provides a flexible genital tract sampler, which aims to improve the brush used to collect bacteria or cells in the genital tract and is set at the end of the sampling rod. Because the inside of the genital tract has more folds and a certain curvature, and the friction between the brush and the inner wall of the genital tract is relatively large compared to the sampling rod, after the sampling rod drives the brush into the patient's genital tract, the brush may be pressed against the folds of the inner wall of the genital tract, causing the bending of the sampling rod to cause discomfort to the patient.

[0006] The utility model is implemented as follows: a flexible reproductive tract sampler, including a protective tube, the protective tube including a tube body, the inner wall of the top opening of the tube body is provided with a threaded groove and a connecting seat is threadedly connected through the threaded groove, a sampling rod is rotatably installed in the connecting seat, the sampling rod includes a rod body, the rod body is made of a plastic material with relatively flexible ductility, the outer wall of one end thereof is annular and has a plurality of installation grooves, and a sampling cotton piece is arranged in each of the installation grooves.

[0007] In a preferred technical solution of the utility model, one end of the rod body is rounded, and a rod head limiting seat adapted thereto is provided on the inner wall of the bottom of the tube body for limiting the rod body.

[0008] In a preferred technical solution of the present invention, the connecting seat includes a seat body, the outer wall of the bottom end of the seat body is provided with a thread adapted to the thread groove, the upper surface of the seat body is provided with a rotating hole that penetrates to the bottom, the end of the rod body close to the seat body is in two sections and the two sections are fixedly connected by a limiting rod, the diameter of the limiting rod is relatively smaller than that of the rod body, and the overall recessed structure of the connecting part is engaged in the rotating hole so that the rod body can only rotate relatively independently and cannot be displaced up and down along its axial direction.

[0009] In a preferred technical solution of the utility model, a rubber seat is provided on a fixed sleeve at one end of the rod body close to the connecting seat.

[0010] In a preferred technical solution of the utility model, a hand-held portion is provided at one end of the rod body located above the connecting seat, and the outer wall of the hand-held portion is designed to be anti-slip.

[0011] In a preferred technical solution of the present utility model, the entire rod body is made of medical PVC, has a smooth overall surface and is a relatively flexible cylindrical structure with strong deformation capability.

[0012] In a preferred technical solution of the present utility model, the tube body is made of opaque medical PVC material, and the rod head limiting seat is integrally arranged with the tube body.

[0013] The beneficial effect of the utility model is that the utility model obtains a flexible reproductive tract sampler through the above design. When in use, because the sampling part is arranged on the outer wall of the circumference of the rod body, and the surface of the rod body is smooth and flexible, and the rounded end at one end can reduce friction when entering the patient's reproductive tract and better fit the curvature of the reproductive tract, it is avoided that the sampling part is arranged at the end of the rod body and after entering the reproductive tract, it is against the folds of the inner wall of the reproductive tract, causing the rod body to bend, causing discomfort to the patient.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a flexible sampler for the reproductive tract, comprising a protective tube 1, the protective tube 1 comprising a tube body 101, a thread groove 102 is arranged on the inner wall at the top opening of the tube body 101, and a connecting seat 2 is threadedly connected through the thread groove 102, a sampling rod 3 is rotatably installed in the connecting seat 2, the sampling rod 3 comprises a rod body 301, the rod body 301 is made of a plastic material with relatively flexible ductility, and a plurality of mounting grooves 302 are arranged on the outer wall of one end thereof in an annular shape, each mounting groove 302 is provided with a sampling cotton piece 303.

[0022] See also Figure 2 One end of the rod body 301 is rounded, and a rod head limit seat 103 adapted thereto is provided on the inner wall of the bottom of the tube body 101 to limit the rod body 301. Since the material of the rod body 301 is relatively flexible, it can prevent the rod body 301 from being displaced due to vibration when it is inside the tube body 101, causing the sampling cotton piece 303 to contact the inner wall of the tube body 101 and causing the sample to adhere to the inner wall of the tube body 101, thereby improving stability during use and avoiding a decrease in sampling accuracy.

[0023] See also Figure 4 The connecting seat 2 includes a seat body 201, and the outer wall of the bottom end of the seat body 201 is provided with a thread 202 adapted to the thread groove 102. A rotating hole 203 that runs through the bottom is opened on the upper surface of the seat body 201. The end of the rod body 301 close to the seat body 201 is two-section and the two sections are fixedly connected by a limiting rod 306. The diameter of the limiting rod 306 is relatively smaller than that of the rod body 301. The overall recessed structure of the connecting part is engaged in the rotating hole 203 so that the rod body 301 can only rotate relatively independently and cannot move up and down along its axial direction. The rod bodies 301 at both ends are fixedly connected by the limiting rod 306. The recessed structure formed between the three and the adapted rotating hole 203 are engaged with each other to limit the rod body 301, thereby further improving the stability during use.

[0024] Furthermore, a rubber seat 304 is fixed on one end of the rod body 301 near the connecting seat 2, and the rubber seat 304 is located below the seat body 201. When sampling the cell flora in the reproductive tract through the rod body 301, the rubber seat 304 can prevent the seat body 201 from contacting the patient's body and causing discomfort to the patient.

[0025] See also Figure 2 and Figure 3 A hand-held portion 305 is provided at one end of the rod body 301 located above the connecting seat 2, and the outer wall of the hand-held portion 305 is designed to be non-slip. When in use, one hand is held on the hand-held portion 305 and the other hand is held on the seat body 201 to insert the rod body 301 into the reproductive tract. The hand-held portion 305 is rotated to drive the rod body 301 to rotate, so that the other end of the rod body 301 rotates in the reproductive tract, so that the several sampling cotton pieces 303 arranged on the outer wall surface circumferentially adhere to the cells or flora on the inner wall of the reproductive tract for sampling, thereby ensuring the sampling efficiency. The non-slip design is a non-slip texture or a non-slip rubber sleeve to ensure that there is no slipping when the rod body 301 is rotated, thereby improving stability.

[0026] Furthermore, the rod body 301 is made of medical PVC as a whole, and has a relatively smooth surface and a relatively flexible cylindrical structure with strong deformation ability. Medical PVC is resistant to chemical corrosion, and has strong resistance to oxidants, reducing agents and strong acids, and is wear-resistant, easy to produce, safe to use and low-cost. The rounded end and smooth surface at one end of the rod body 301 can reduce the friction between it and the inner wall of the reproductive tract, and will not cause discomfort to the patient due to bending due to contact with the folds in the reproductive tract. During the insertion process of the rod body 301 into the reproductive tract, it will bend synchronously with the complete structure of the reproductive tract, thereby further reducing the patient's discomfort.

[0027] Furthermore, the tube body 101 is made of opaque medical PVC material, and the rod head limit seat 103 is integrally arranged with the tube body 101. The opaque tube body 101 can prevent some cells or bacterial colonies from being affected by the light environment during transportation, resulting in a decrease in detection accuracy. The integral arrangement of the rod head limit seat 103 and the tube body 101 can also relatively improve the stability of use, and prevent the rod head limit seat 103 from falling off and adhering to the rod body 301, causing it to accidentally enter the patient's body.

[0028] Working principle: The rod body 301 is pulled out from the inside of the tube body 101 by rotating the seat body 201, and the seat body 201 is held by one hand and the hand-held part 305 is held by the other hand, and the end of the rod body 301 with a rounded part is slowly inserted into the patient's reproductive tract. After reaching the appropriate depth, the hand-held part 305 is rotated to drive the rod body 301 to rotate in the reproductive tract, so that the several sampling cotton pieces 303 arranged on the outer wall of the rod body 301 adhere to and collect cells or bacteria on the inner wall of the reproductive tract in a circumferential direction. After collection, the rod body 301 is pulled out and reinserted into the tube body 101, and the rod head limit seat 103 is used to fix it. The end is limited to prevent the sampling cotton piece 303 with cells or bacteria attached to it from contacting the inner wall of the tube body 101, and the seat body 201 is connected to the tube mouth of the tube body 101 through the thread 202 and the thread groove 102. Since the sampling part is arranged on the outer wall of the circumference of the rod body 301, and the surface of the rod body 301 is smooth and flexible, the rounded end at one end can reduce friction when entering the patient's reproductive tract, thereby preventing the sampling part arranged at the end of the rod body 301 from pressing against the folds of the inner wall of the reproductive tract after entering the reproductive tract, causing the rod body 301 to bend, causing discomfort to the patient.

[0029] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
