Description

Technical Field

[0001] The utility model relates to the technical field of gynecological medical appliances, in particular to a cervical liquid-based cell sampling brush. Background Art

[0002] Cervical examination is an important indicator for the diagnosis and treatment of gynecological diseases. When gynecologists perform cervical examinations on patients, they often need to collect cervical fluid for disease diagnosis. Scientific and accurate sampling is the basis for ensuring the accuracy of the examination results. If the sampling is inappropriate, it will lead to errors in the examination results.

[0003] At present, the gynecological cervical liquid-based cell sampling operation requires the use of a vaginal dilator to open the patient's vagina, and then inserting a cotton swab into the patient's cervical opening to dip the cervical fluid. The process is cumbersome and inconvenient, and the cervical fluid dipped by the cotton swab is easily contaminated by contact with the patient's vulva when it is taken out, affecting the accuracy of the cervical fluid sample detection. Utility Model Content

[0004] The present invention relates to a cervical liquid-based cell sampling brush, which solves the problem that the current gynecological cervical liquid-based cell sampling operation needs to use a vaginal dilator to open the patient's vagina, and then insert a cotton swab into the patient's cervical opening to dip the cervical fluid. The process is cumbersome and inconvenient, and the cervical fluid dipped by the cotton swab is easily contaminated by contact with the patient's vulva when being taken out, thus affecting the accuracy of cervical fluid sample detection.

[0005] In a first aspect of the present disclosure, a cervical liquid-based cell sampling brush is provided, which specifically includes: a sampling sleeve; the sampling sleeve is provided with two connecting holes on the outside, the sampling sleeve is connected to a cover body on the outside, the cover body is provided with two hooks on the outside, and the hooks are connected to the connecting holes; a sampling rod is connected to the inside of the cover body, a pull ring is provided at one end of the sampling rod, and a sampling brush head is threadedly connected to the other end of the sampling rod, and the sampling brush head is located in the sampling sleeve.

[0006] Furthermore, the sampling sleeve is provided with an external thread on the outside, and a moisturizing shell is mounted on the outside of the sampling sleeve. The moisturizing shell is provided with an internal thread on the inside. The moisturizing shell is threadedly connected to the sampling sleeve, and a lubricant is contained in the contact gap between the moisturizing shell and the sampling sleeve.

[0007] Furthermore, the end of the sampling sleeve is rounded and smooth, and a sampling inlet and outlet are provided at the end of the sampling sleeve, and the sampling brush head moves in the sampling inlet and outlet provided on the sampling sleeve.

[0008] Furthermore, a movable through hole is provided inside the cover body, and the sampling rod is slidably connected to the movable through hole provided in the cover body. The moisturizing shell moisturizes the external lubricant of the sampling sleeve, so that the smooth end of the sampling sleeve can be easily inserted into the patient's vagina, reducing the resistance and discomfort during insertion. The sampling sleeve prevents the sampling brush head from contacting the patient's vulva during the insertion and extraction process, causing contamination to the sampling brush head.

[0009] Furthermore, two movable blocks are provided inside the movable through hole, a J-shaped groove is provided outside the sampling rod, and the movable block is slidably connected to the J-shaped groove provided on the sampling rod.

[0010] Furthermore, a spring is mounted on the outside of the sampling rod, and the spring is located in the sampling sleeve. One end of the spring is in contact with the cover body, and the other end of the spring is in contact with the sampling brush head. When the sampling brush head is in the sampling sleeve, the spring is in a contracted state, and the movable block is located at the innermost end of the J-shaped groove, thereby ensuring the stability of the sampling brush head inside the sampling sleeve.

[0011] Furthermore, an annular groove is provided on the outside of the sampling rod, which is connected to the two J-shaped grooves. The movable block is slidably connected to the annular groove provided on the sampling rod. When the movable block moves into the annular groove through the J-shaped groove, the rotation of the sampling rod is unrestricted, and the sampling brush head can be driven to rotate through the sampling rod.

[0012] The utility model provides a cervical liquid-based cell sampling brush, which has the following beneficial effects:

[0013] When the utility model is in use, the moisturizing shell has a moisturizing effect on the external lubricant of the sampling sleeve, so that the smooth end of the sampling sleeve can be easily inserted into the patient's vagina, reducing the resistance and discomfort during insertion, and the sampling sleeve prevents the sampling brush head from contacting the patient's vulva during the insertion and extraction process, thereby contaminating the sampling brush head, and drives the sampling brush head to move outward through the sampling rod, so that the sampling brush head contacts the cervical opening, thereby achieving the sampling operation of cervical fluid secreted by the cervical opening and ensuring the cervical fluid sampling effect.

[0014] In addition, when the sampling brush head is inside the sampling sleeve, the spring is in a contracted state, and the movable block is located at the innermost end of the J-shaped groove, thereby ensuring the stability of the sampling brush head inside the sampling sleeve. When the sampling brush head needs to be moved to the outside of the sampling inlet and outlet for sampling and maintenance, it is necessary to first pull the sampling rod backwards, and then rotate the sampling rod to make the movable block leave the innermost end of the J-shaped groove, and the sampling brush head moves outward under the influence of the spring thrust to achieve the sampling operation. When the movable block moves into the annular groove through the J-shaped groove, the rotation of the sampling rod is unrestricted, and the sampling brush head can be driven to rotate through the sampling rod to perform rotation sampling operations on the cervical opening, thereby further ensuring the cervical fluid sampling effect.

[0015] Other advantages, objectives and features of the present invention will be reflected in part through the following description, and in part will be understood by those skilled in the art through research and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
