[0063] The words "first", "second" and the like in the terminology of the present invention are used for descriptive purposes only and should not be understood as indicating or implying relative importance, and should not be construed as limiting the order of precedence.
[0064] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0065] In the actual sampling process, the uterus of women in different regions and ages is different. The structure of the sampling brush in the prior art is not conducive to the operator to determine the insertion depth for women in different regions and ages, which will affect the sampling accuracy and ultimately lead to inaccurate test results. At the same time, the structure of the disposable endometrial sampling brush in the prior art is not conducive to the operator to control the rotation amplitude of the bristles. If the rotation amplitude is too small, it is impossible to obtain enough mucosal fragment samples, and if the rotation amplitude is too large, it is easy to damage the uterine wall.
[0066] The following is a preferred embodiment of a disposable endometrial sampling brush provided by the present invention that can solve the above technical problems.
[0067] Please refer to Figure 1 and Figure 2The first preferred embodiment of the utility model provides a disposable endometrial sampling brush, which is used to be placed in the uterine cavity and scrape the mucosal fragments in the uterine cavity. The disposable endometrial sampling brush includes a connecting rod 11, bristles 12, a stopper 13 and a protective tube 14. The connecting rod 11 is in a straight strip shape, and its two ends are respectively a first end 111 and a second end 112. The bristles 12 are distributed around the first end 111 along the circumference and axial direction of the connecting rod 11. The stopper 13 is fixed to the end of the first end 111 and is located on the side of the bristles 12 away from the second end 112. The protective tube 14 is movably sleeved on the connecting rod 11 and the bristles 12. The protective tube 14 is used to protect the bristles 12, and the inner diameter of the protective tube 14 is smaller than the size of the stopper 13. The protective tube 14 is distributed along its axial direction with multiple depth marks 141 for entering the uterine cavity. The protective tube 14 can be made of transparent polypropylene. The limiting member 13 is spherical, which can not only limit the protection tube 14 but also avoid damaging the uterine cavity, and can also seal the protection tube 14 to prevent the bristles 12 from being contaminated.
[0068] The disposable endometrial sampling brush of the utility model is firstly placed in contact with the protection tube 14 and the limiting member 13 before being inserted into the uterine cavity. Figure 2 By setting a plurality of depth marks 141 for entering the uterine cavity, the operator can determine the insertion depth according to the region and age of the person being tested, that is, when the protection tube 14 abuts against the stopper 13, different distances from the depth marks 141 for entering the uterine cavity to the stopper 13 correspond to the detection requirements of the uterine cavity of women of different regions and ages. The disposable endometrial sampling brush of the utility model is convenient for the operator to select a suitable insertion depth according to the uterine cavity of women of different regions and ages, making the operation convenient and the sampling accurate.
[0069] Please continue to refer to Figure 1 The depth mark 141 of entering the uterine cavity is a scale line. This structure is convenient for the operator to accurately determine the depth of insertion.
[0070] Please continue to refer to Figure 1 The number of the depth mark 141 of entering the uterine cavity is three, that is, three scale lines are set, representing the depth marks of 6 cm, 7 cm and 8 cm respectively. In this structure, three detection positions of 6 cm, 7 cm and 8 cm are set, which can meet the detection requirements of the uterine cavity of women in different regions and ages, and the processing is simple, and it is also easy for the operator to remember and use.
[0071] Please continue to refer to Figure 1The protective tube 14 is also provided with different scale numbers, which correspond to different depth marks 141 of entering the uterine cavity, and the scale numbers shown in the figure are 6cm, 7cm and 8cm respectively. This structure makes it more intuitive for the operator to use, and it is also convenient for the operator to remember the different depth marks 141 of entering the uterine cavity corresponding to the uterine cavity of women in different regions and ages, that is, the operator can choose to use the first depth mark 141 of entering the uterine cavity, the second depth mark 141 of entering the uterine cavity, or the depth mark 141 of entering the uterine cavity by memorizing 6cm, 7cm or 8cm.
[0072] Please continue to refer to Figure 1 The depth mark 141 of entering the uterine cavity is of different fluorescent colors. This structure enables the operator to clearly identify the different depth marks 141 of entering the uterine cavity.
[0073] Please continue to refer to Figure 1 The disposable endometrial sampling brush also includes a handle 15, which is fixed at the second end 112. The handle 15 is provided with an angle marking structure 151 for indicating the rotation angle along its circumference. During the detection process, the handle 15 needs to be rotated so that the bristles 12 rotate, thereby scraping the mucosal fragments in the uterine cavity. If the rotation angle is too large, the uterine cavity will be damaged. If the rotation angle is too small, sufficient mucosal fragments cannot be obtained, which does not meet the sampling requirements. With the above structure, the operator can accurately rotate the angle of the handle 15 according to the detection requirements.
[0074] Please continue to refer to Figure 1 , the angle marking structure 151 is a plurality of angle lines and corresponding angle numbers. The figure shows that 4 angle numbers are marked, namely 0°, 90°, 180° and 270°. This structure allows the operator to accurately grasp the rotation angle of the handle 15, which is convenient to use.
[0075] Please continue to refer to Figure 1 The connecting rod 11 is formed by winding two steel wires. The disposable endometrial sampling brush also includes a reinforcing rod made of resin (the reinforcing rod is blocked by the protective tube 14, Figure 1 The reinforcing rod 14 is not shown in the figure, and the fixing sleeve is arranged at a section of the connecting rod 11 away from the bristles 12, and the protective tube 14 is arranged outside the reinforcing rod. The two steel wires are wound to fix the bristles 12, but the steel wires are relatively soft and the connecting rod 11 is relatively slender, which makes the connecting rod 11 easy to bend and inconvenient to insert into the uterine cavity. The reinforcing rod in the above structure can reinforce the connecting rod 11, which is convenient for the operator to use.
[0076] Please refer to Figure 3The second preferred embodiment of the utility model provides a disposable endometrial sampling brush, which is used to be placed in the uterine cavity and scrape the mucosal fragments in the uterine cavity. The disposable endometrial sampling brush includes a connecting rod 21, bristles 22, a limiter 23 and a protective tube 24. The connecting rod 21 is in the shape of a straight bar, and its two ends are respectively a first end 211 and a second end 212. The bristles 22 are distributed around the first end 211 along the circumference and axial direction of the connecting rod 21. The limiter 23 is fixed to the end of the first end 211 and is located on the side of the bristles 22 away from the second end 212. The protective tube 24 is movably sleeved on the connecting rod 21 and the bristles 22. The protective tube 24 is used to protect the bristles 22, and the inner diameter of the protective tube 24 is smaller than the size of the limiter 23. The protective tube 24 is distributed along its axial direction with a plurality of depth marks 241 for entering the uterine cavity.
[0077] The disposable endometrial sampling brush of the utility model first abuts the protective tube 24 with the stopper 23 before inserting into the uterine cavity. By setting a plurality of depth marks 241 for entering the uterine cavity, the operator can determine the insertion depth according to the region and age of the person being tested, that is, when the protective tube 24 abuts with the stopper 23, the distances from the different depth marks 241 for entering the uterine cavity to the stopper 23 correspond to the detection requirements of the uterine cavity of women of different regions and ages. The disposable endometrial sampling brush of the utility model is convenient for the operator to select a suitable insertion depth according to the uterine cavity of women of different regions and ages, so that the operation is convenient and the sampling is accurate.
[0078] Please continue to refer to Figure 3 The depth mark 241 of entering the uterine cavity is a ribbon of different colors. The depth mark 241 of entering the uterine cavity of this structure, that is, the ribbon of different colors, is more eye-catching. When the detection requirement is to extend into a certain area of the uterine cavity, this structure is convenient for the operator to operate according to the detection requirement.
[0079] Please continue to refer to Figure 3 The number of depth marks 241 entering the uterine cavity is three, that is, three color bands are set, representing the depth marks of 6 cm, 7 cm and 8 cm respectively. In this structure, three detection positions of 6 cm, 7 cm and 8 cm are set, which can meet the detection requirements of the uterine cavity of women in different regions and ages, and the processing is simple, and it is also easy for the operator to remember and use.
[0080] Please continue to refer to Figure 3 The protective tube 24 is also provided with different scale numbers, which correspond to different depth marks 241 of entering the uterine cavity. The scale numbers shown in the figure are 6cm, 7cm and 8cm respectively. This structure makes it more intuitive for the operator to use, and it is also convenient for the operator to remember the different depth marks 241 of entering the uterine cavity corresponding to the uterine cavity of women of different regions and ages.
[0081] Please continue to refer to Figure 3The depth mark 241 of entering the uterine cavity is of different fluorescent colors. This structure enables the operator to clearly identify the different depth marks 241 of entering the uterine cavity.
[0082] Please continue to refer to Figure 3 The disposable endometrial sampling brush also includes a handle 25, which is fixed at the second end 212. The handle 25 is provided with an angle marking structure 251 for indicating the rotation angle along its circumference. During the detection process, the handle 25 needs to be rotated so that the bristles 22 rotate, thereby scraping the mucosal fragments in the uterine cavity. If the rotation angle is too large, the uterine cavity will be damaged. If the rotation angle is too small, sufficient mucosal fragments cannot be obtained, which does not meet the sampling requirements. With the above structure, the operator can accurately rotate the angle of the handle 25 according to the detection requirements.
[0083] Please continue to refer to Figure 3 , the angle identification structure 251 is a plurality of color bands of different colors and a plurality of corresponding angles. The figure shows four color bands of different colors, each color band occupies an angle of 90°, and the angles are marked at the intersections of different color bands, which are 0°, 90°, 180° and 270° respectively. The angle identification structure 251 in this structure is more eye-catching, can meet the requirements of rotation accuracy, and is also convenient to use.
[0084] It should be noted that the depth marking and angle marking structures for entering the uterine cavity of the disposable endometrial sampling brush of the first preferred embodiment and the disposable endometrial sampling brush of the second preferred embodiment can be cross-set to form other embodiments, which will not be repeated here.
[0085] The method of using the disposable endometrial sampling brush of the first preferred embodiment of the utility model is as follows:
[0086] 1. Use a vaginal dilator to open the female vagina;
[0087] 2. Determine the depth mark 141 of entering the uterine cavity that should be used according to the region and age of the subject to be tested. For example, if the subject to be tested is a European or American woman, the operating specification requires that the depth mark 141 of entering the uterine cavity be 8 cm.
[0088] 3. Push the protection tube 14 upwards so that the protection tube 14 and the stopper 13 are in contact with each other. At this time, the bristles 12 are completely wrapped in the protection tube 14 to prevent them from being contaminated during the insertion process. Then, insert the bristles 12 into the uterine cavity through the vagina until the 8 cm depth mark 141 of the uterine cavity disappears from sight. Then stop inserting. At this time, the bristles 12 have reached a suitable position.
[0089] 4. Pull the protective tube 14 downward so that the bristles 12 are separated from the protective tube 14 and can directly contact the uterine cavity;
[0090] 5. Slowly rotate the handle 15 to a suitable rotation angle according to the preset operation specification, so that the bristles 12 rotate to a suitable rotation angle, thereby scraping the mucosal fragments in the uterine cavity. For example, when the preset operation specification is to rotate three times clockwise, the 0° scale line can be directly facing the line of sight before rotation, and the handle 15 can be rotated clockwise. When the 0° scale line returns to the initial position for the third time, it means that the handle has been rotated three times clockwise;
[0091] 6. Push the protective tube 14 upward again, so that the protective tube 14 and the limiter 13 remain in contact with each other. At this time, the bristles 12 are completely wrapped in the protective tube 14 again to prevent the collected mucosal fragments from being contaminated. Then pull the disposable endometrial sampling brush outward to remove it from the uterine cavity.
[0092] 7. Soak the bristles that have collected the mucosal fragments in the professional reagent for a while, and swing the bristles to allow the mucosal fragments to enter the reagent. Then take the disposable endometrial sampling brush out of the reagent for unified treatment, seal the reagent and proceed to the next step of testing.
[0093] This is the method of using the disposable endometrial sampling brush of the first preferred embodiment.
[0094] Please refer to Figure 4 The third preferred embodiment of the utility model provides a disposable endometrial sampling brush, which is used to be placed in the uterine cavity and scrape the mucosal fragments in the uterine cavity. The disposable endometrial sampling brush includes a connecting rod 31, bristles 32, a protective tube 33 and a handle 34. The connecting rod 31 is in a straight strip shape, and its two ends are respectively a first end 311 and a second end 312.

The handle 34 is fixed on the second end 312, the handle 34 is coaxial with the connecting rod 31, and the handle 34 is provided with an angle marking structure 341 for indicating the rotation angle along its circumference. The protective tube 33 can be made of transparent polypropylene.
[0095] With the disposable endometrial sampling brush of the present invention, the operator can accurately control the angle at which the handle 34 needs to be rotated through the angle marking structure 341, thereby accurately controlling the rotation angle of the bristles 32, so as to obtain sufficient mucosal fragment samples and avoid damaging the uterine wall as much as possible, and the use is very convenient.
[0096] Please continue to refer to Figure 4 The angle marking structure 341 is a plurality of angle lines and a plurality of corresponding angle numbers. This structure enables the operator to accurately grasp the rotation angle of the handle 34, and is convenient to use.

The stopper 35 is spherical, which can not only limit the protective tube 33, but also avoid damaging the uterine cavity, and can also seal the protective tube 33 to prevent contamination of the bristles 32. In this structure, before the disposable endometrial sampling brush is inserted into the uterine cavity, the protective tube 33 is first abutted against the stopper 35. By setting a plurality of depth marks 331 for entering the uterine cavity, the operator can determine the depth of insertion according to the region and age of the person being tested, that is, when the protective tube 33 is abutted against the stopper 35, the distances from the different depth marks 331 for entering the uterine cavity to the stopper 35 correspond to the detection requirements of the uterine cavity of women in different regions and ages. This structure allows the operator to select a suitable insertion depth according to the uterine cavity of women in different regions and ages, thereby making the operation convenient and the sampling accurate.
[0100] Please continue to refer to Figure 4 and Figure 5 The depth mark 331 of entering the uterine cavity is a scale line. This structure is convenient for the operator to accurately determine the depth of insertion.

[0115] The method of using the disposable endometrial sampling brush of the third preferred embodiment of the utility model is as follows:
[0116] 1. Use a vaginal dilator to open the female vagina;
[0117] 2. Determine the depth mark 331 of entering the uterine cavity that should be used according to the region and age of the subject to be tested. For example, if the subject to be tested is a European or American woman, the operating specification requires that the depth mark 331 of entering the uterine cavity be 8 cm;
[0118] 3. Push the protection tube 33 upwards so that the protection tube 33 and the stopper 35 are in contact with each other. At this time, the bristles 32 are completely wrapped in the protection tube 33 to prevent them from being contaminated during the insertion process. Then, insert the bristles 32 into the uterine cavity through the vagina until the 8 cm depth mark 331 of entering the uterine cavity disappears from sight. Then stop inserting. At this time, the bristles 32 have reached a suitable position.
[0119] 4. Pull the protective tube 33 downward so that the bristles 32 are separated from the protective tube 33 and can directly contact the uterine cavity;
[0120] 5. Slowly rotate the handle 34 to a suitable rotation angle according to the preset operation specification, so that the bristles 32 rotate to a suitable angle, thereby scraping the mucosal fragments in the uterine cavity. For example, when the preset operation specification is to rotate three times clockwise, before rotating, the handle 34 can be rotated clockwise when the 0° scale line is directly facing the line of sight. When the 0° scale line returns to the initial position for the third time, it means that the handle has been rotated three times clockwise;
[0121] 6. Push the protection tube 33 upward again, so that the protection tube 33 and the limiter 35 remain in contact with each other. At this time, the bristles 32 are completely wrapped in the protection tube 33 again to prevent the collected mucosal fragments from being contaminated. Then pull the disposable endometrial sampling brush outward to remove it from the uterine cavity.
[0122] 7. Soak the bristles 32 with collected mucosal fragments in a professional reagent for a while, and swing the bristles 32 to allow the mucosal fragments to enter the reagent, then take the disposable endometrial sampling brush out of the reagent for unified treatment, seal the reagent and proceed to the next step of testing.
[0123] This is the method of using the disposable endometrial sampling brush of the third preferred embodiment.
[0124] The disposable endometrial sampling brush of the utility model first abuts the protective tube against the limiter before inserting into the uterine cavity. By setting a plurality of depth marks for entering the uterine cavity, the operator can determine the insertion depth according to the region and age of the person being tested, that is, when the protective tube abuts against the limiter, the distances from different depth marks for entering the uterine cavity to the limiter correspond to the detection requirements of the uterine cavity of women of different regions and ages. The disposable endometrial sampling brush of the utility model is convenient for the operator to select a suitable insertion depth according to the uterine cavity of women of different regions and ages, so that the operation is convenient and the sampling is accurate.
[0125] With the disposable endometrial sampling brush of the utility model, the operator can accurately control the angle at which the handle needs to be rotated through the angle marking structure, thereby accurately controlling the rotation angle of the bristles, thereby obtaining sufficient mucosal fragment samples and avoiding damage to the uterine wall as much as possible, and the use of the brush is very convenient.
