Description

Technical Field

[0001] The utility model relates to the technical field of screening brushes, in particular to a cervical disease screening brush. Background Art

[0002] In recent years, with the promotion and development of cervical precancer screening, the clinical detection rate of cervical intraepithelial neoplasia and cervical cancer has been significantly improved, so that timely intervention can be carried out to prevent its further development. At present, the two types of cervical precancer screening generally accepted by everyone are liquid-based thin-layer cytology (TCT) and HPV testing. When conducting the examination, you need to use a vaginal dilator to open the vagina, and then insert the cervical brush into the cervical opening, and rotate the cervical brush at the cervical opening for several circles to remove the exfoliated cells at the cervical opening. After the cervical brush is removed, the exfoliated cells can be directly coated on a slide and observed under a microscope, or they can be stored in a preservation solution and sent to the laboratory for testing.

[0003] However, during the current sample collection process, medical staff are required to hold the dilator in one hand and use the other hand to hold a brush to rotate the patient to collect samples. When actually using a cervical brush for sampling, the cervical brush needs to be rotated 5-10 times, or even more than ten times, at the cervical opening in order to collect more exfoliated cells to ensure the accuracy of the test results. Therefore, prolonged operation will make it very likely that the cervical brush will deviate from the cervical opening during rotation, which will lead to inaccurate sampling. In addition, the cervical brush will shake when manually operating it for sampling, which will cause damage to the woman's cervix. At the same time, two different cervical brushes are required for the two test items, so the operation time is longer and the patient's comfort level is not high. Utility Model Content
