Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a sampling device. Background Art

[0002] Gynecology focuses on the health of the female reproductive system, covering the diagnosis and treatment of a variety of diseases. Gynecological examination, as a key link in protecting women's health, is a comprehensive health assessment of the female reproductive system. It carefully covers the vulva, vagina, cervix, uterus and appendages, and uses visual examination, palpation and instrument examination to accurately detect various diseases such as inflammation, tumors, and endocrine disorders. During the examination, female vaginal secretions will be extracted or the vaginal cavity will be inspected. By testing the secretions and observing the vaginal wall and external reactions, an in-depth understanding of the patient's condition can be obtained, providing a strong basis for accurate diagnosis, helping women to promptly discover health risks, achieve early diagnosis and treatment, and effectively maintain women's reproductive health.

[0003] At present, different instruments are used to assist in extracting or examining female vaginal secretions or the vaginal cavity. In order to prevent cross infection, most hospitals use disposable secretion extraction devices, which insert a sanitary cotton swab into the vagina to extract secretions. If the vaginal secretions of the person being examined are less, the doctor needs to insert the swab deeper, and the hand will directly contact the patient's private skin, which not only brings a bad feeling to the person being examined, but also makes it difficult to use the cotton swab to penetrate deeper, including the extraction of cells on the inner wall of the uterus and cervix, which is difficult to achieve with the length of an ordinary cotton swab. In addition, when sampling with a sanitary cotton swab, when the medical staff pulls the sanitary cotton swab out of the patient's body, it will be attached to other parts of the patient's body. After being contaminated, the sample will be attached to specimens from other parts of the patient's body, resulting in errors in the test results, reducing the accuracy and efficiency of the test results. Therefore, a sampling device is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem in the prior art that a sanitary cotton swab is inserted into the vagina to extract secretions. If the vaginal secretions of the person being examined are less, the doctor needs to insert the swab deeper, and the hand is in direct contact with the patient's private skin, which not only gives the person being examined a bad feeling, but also makes it difficult to use the cotton swab to penetrate deeper, including the extraction of cells on the inner wall of the uterus and cervix, which is difficult to achieve with the length of an ordinary cotton swab. When sampling with a sanitary cotton swab, when the medical staff pulls the sanitary cotton swab out of the patient's body, it will stick to other parts of the patient's body. After being contaminated, the sample will stick to specimens from other parts of the patient's body, resulting in errors in the test results. A sampling device is proposed.

[0018] 1. In the present invention, the expansion ring is driven to move by rotating the movable ring in the expansion assembly, and the support rod is used to expand the multiple expansion plates outward, thereby expanding the soft sleeve inside the patient's body and effectively expanding the vagina. This avoids excessive direct contact between the doctor's hands and the patient's private skin, reducing the discomfort of the person being examined; at the same time, after the vagina is expanded, a wider operating space can be created, allowing the sampling rod to reach the vagina and even the inner wall of the uterine cervix more smoothly and deeply, overcoming the problem that ordinary cotton swabs are insufficient in length and difficult to penetrate deeply.

[0019] 2. In the present invention, the vagina is stretched open in the sampling assembly and the inner sleeve is pushed to slide. The sampling rod can move with it. When the sampling position is reached, the doctor can manually push the sampling rod to drive the sampling sleeve to separate from the inner sleeve and move at any angle, accurately fitting the inner wall of the vagina and cervix for sampling. After the sampling is completed, the sampling rod is pulled, and the sampling sleeve is returned to the center of the inner sleeve with the help of the spring and elastic rubber sheet, avoiding the shortcomings of ordinary cotton swab sampling, enabling deep internal sampling, reducing specimen contamination, improving sampling accuracy, and flexibly adjusting the sampling angle to improve the accuracy and efficiency of the test results.
