Description

Technical Field

[0001] The utility model relates to the technical field of medical detection, in particular to a self-collecting device for female reproductive tract secretions. Background Art

[0002] If the female reproductive tract has too many sexual partners, frequent sexual intercourse, vaginal douching, and unclean sanitary products, it may cause the reproductive tract flora disorder and microenvironment imbalance. Imbalanced flora is often accompanied by the occurrence of various gynecological diseases such as vaginitis, cervical cancer, and infertility. In order to effectively guide clinical medication, it is necessary to sample the reproductive tract secretions and send them to the laboratory for testing after sampling;

[0003] Existing methods of sampling female reproductive tract secretions usually require patients to go to the hospital, and a professional doctor will use a dilator to stretch the reproductive tract for sampling. This process is rather laborious, and in order to ensure accuracy, multiple cotton swabs are usually required for sampling. The sampling is done in sequence, and the intervals between replacements are relatively long. At the same time, the reproductive tract is in an open state, and bacteria can easily enter the reproductive tract and cause infection. Utility Model Content

[0004] The main purpose of the utility model is to provide a self-collecting device for female reproductive tract secretions, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A self-collecting device for female reproductive tract secretions, comprising a sampling outer cylinder, a sampling assembly is arranged inside the sampling outer cylinder, the sampling assembly comprises a mounting head, and an internal thread matching the mounting head is provided inside the sampling outer cylinder;

[0007] The outer ring of the mounting head is provided with an external thread matching the thread of the sampling outer cylinder, and the mounting head thread is installed inside the sampling outer cylinder, and a plurality of equidistantly arranged through holes are opened through the upper and lower ends of the mounting head, and the sampling swab body is arranged inside the through holes. The top of the mounting head is provided with a locking sleeve whose through holes match each other, and the outer ring of the locking sleeve is threadedly connected with a locking head.

[0008] As a further solution of the utility model, a plurality of the sampling swab bodies pass through the locking bite sleeve, and the sampling swab bodies are movably connected to the locking bite sleeve, the locking head, and the mounting head.

[0009] As a further solution of the utility model, an arc plate is fixedly connected to the upper position of the outer ring of the sampling outer cylinder, and a holding head is fixedly connected to the top and front and rear ends of the arc plate, and the outer ring of the holding head is provided with anti-slip texture.

[0010] As a further solution of the utility model, the upper portion of the sampling outer cylinder is cylindrical, and the lower portion of the sampling outer cylinder is arc-shaped.

[0011] As a further solution of the utility model, a guide plate is fixedly connected to the lower inner part of the sampling outer tube, and limiting holes are provided through the upper and lower ends of the guide plate, and the sampling swab body extends out of the sampling outer tube through the limiting holes.

[0012] As a further solution of the utility model, a breaking groove is provided at the lower position of the outer ring of the sampling swab body, a soft swab head is provided at the bottom of the sampling swab body, and the size of the upper limit hole of the guide plate is larger than the size of the soft swab head.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model provides a sampling assembly in conjunction with a sampling outer cylinder. When a patient samples the reproductive tract, the sampling swab body is installed inside the sampling outer cylinder by a locking head, and the sampling outer cylinder is inserted into a suitable position in the reproductive tract. There is no need to use a vaginal dilator to expand the reproductive tract, which is convenient for the patient to take samples by himself. At the same time, when the sampling swab body is taken out, it can be directly passed through the inside of the sampling outer cylinder to prevent contamination caused by contact with the skin, thereby improving the accuracy of subsequent detection.

[0015] By arranging the locking head, the locking bite sleeve, and the sampling swab body to cooperate with each other, during testing, multiple sampling swab bodies can be installed on the mounting head as needed, without the need to insert the sampling swab bodies one by one for testing, thereby improving the detection efficiency, preventing a large number of bacteria from entering the female reproductive tract, facilitating reducing the pain of patients during sampling, and eliminating the need for multiple samplings, which can alleviate the psychological pressure that may exist in some patients.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-3 As shown, a self-collecting device for female reproductive tract secretions includes a sampling outer tube 1, a sampling assembly 2 is arranged inside the sampling outer tube 1, the sampling assembly 2 includes a mounting head 3, and an internal thread matching the mounting head 3 is provided inside the sampling outer tube 1;

[0022] The outer ring of the mounting head 3 is provided with an external thread matching the thread of the sampling outer tube 1, and the mounting head 3 is threadedly installed inside the sampling outer tube 1, and a plurality of equidistantly arranged through holes are opened through the upper and lower ends of the mounting head 3, and a sampling swab body 6 is arranged inside the through holes. The top of the mounting head 3 is provided with a locking bite sleeve 4 whose through holes match each other, and the outer ring of the locking bite sleeve 4 is threadedly connected with a locking head 5.

[0023] In this embodiment, a number of sampling swab bodies 6 pass through the locking sleeve 4, and the sampling swab bodies 6 are movably connected with the locking sleeve 4, the locking head 5, and the mounting head 3. The locking sleeve 4 is squeezed by twisting the locking head 5, which facilitates the locking of the sampling swab bodies 6 and prevents the sampling swab bodies 6 from being separated from the mounting head 3 during sampling.

[0024] In this embodiment, an arc-shaped plate 8 is fixedly connected to the upper position of the outer ring of the sampling outer tube 1, and a holding head 9 is fixedly connected to the top of the arc-shaped plate 8 at the front and rear ends, and the outer ring of the holding head 9 is provided with anti-slip grooves. A person can hold the holding head 9 and then gently rotate the sampling outer tube 1 five to eight times in the reproductive tract, so as to collect secretions from the inner wall of the reproductive tract opening or the posterior fornix.

[0025] In this embodiment, the upper portion of the sampling outer tube 1 is cylindrical, and the lower portion of the sampling outer tube 1 is arc-shaped. The arc-shaped lower portion of the sampling outer tube 1 reduces friction when inserted into the reproductive tract and reduces damage to the reproductive tract.

[0026] In this embodiment, a guide plate 7 is fixedly connected to the lower inner portion of the sampling outer tube 1, and limiting holes are provided through the upper and lower ends of the guide plate 7, and the sampling swab body 6 extends through the limiting holes and extends out of the sampling outer tube 1. The guide plate 7 is provided to limit the plurality of sampling swab bodies 6 to prevent them from being squeezed and contracted together by the reproductive tract, thereby facilitating the unfolding of the sampling swab body 6.

[0027] In this embodiment, a breaking groove is provided at the lower position of the outer circle of the sampling swab body 6, and a soft swab head is provided at the bottom of the sampling swab body 6, and the size of the upper limit hole of the guide plate 7 is larger than the size of the soft swab head. The setting of the breaking groove facilitates the removal of the soft swab head, and the size of the limiting hole of the guide plate 7 is larger than the soft swab head, which facilitates the passage of the soft swab head.

[0028] It should be noted that the utility model is a self-collecting device for female reproductive tract secretions. When in use, first, the sampling outer cylinder 1 can be disinfected as needed, and then multiple sampling swab bodies 6 can be taken out of the package without completely removing the package, and the cotton head can be left in the package. Then, the handheld end of the sampling swab body 6 can be passed through the through hole on the mounting head 3 and extended from the top, and then the locking head 5 can be twisted to squeeze the locking bite sleeve 4 to lock the sampling swab body 6. After multiple sampling swab bodies 6 are fixed according to the above steps, all packages can be pulled down, and then the mounting head 3 can be screwed into the sampling outer cylinder 1;

[0029] Then, the sampling outer cylinder 1 is passed through the entrance of the reproductive tract and inserted into the patient's reproductive tract at a distance of three to four centimeters. Then, the locking head 5 locked at the sampling swab body 6 can be loosened to extend all the sampling swab bodies 6 from the guide plate 7 at the bottom of the sampling outer cylinder 1, so that the sampling swab body 6 is located at the inner wall or posterior fornix of the reproductive tract. Then, the sampling swab body 6 can be locked again, and the sampling outer cylinder 1 can be gently rotated five to eight times by holding the holding head 9 as needed to collect secretions at the inner wall or posterior fornix of the reproductive tract entrance.

[0030] After sampling, the locking heads 5 can be loosened one by one, and the sampling swab body 6 after sampling is completed can be retracted into the interior of the sampling outer tube 1 again. Then, the mounting head 3 can be unscrewed to take the sampling swab body 6 out of the interior of the sampling outer tube 1 to separate it from the patient's reproductive tract. Then, an appropriate number of external sampling tubes and external medical self-sealing bags can be selected according to the number of sampling swab bodies 6. Then, the heads of multiple collected sampling swab bodies 6 can be respectively inserted into the external sampling tubes, and the sampling heads can be broken along the breaking groove of the sampling swab body 6. Then, the bottle cap can be tightened and shaken for more than ten times, and then the external sampling bottle can be placed in the external medical self-sealing bag to complete the sampling process.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
