Description

Technical Field

[0001] The present application relates to a cervical detection device, and in particular to a cervical sampling swab. Background Art

[0002] The cervical test kit is a medical device commonly used in gynecological examinations. Its function is to collect cervical cell samples for subsequent pathological examinations. It mainly uses the principle of natural cell shedding to collect cell samples on the surface of the cervix. During the examination, the doctor inserts a disposable cervical test kit into the cervical canal. The brush head on the test kit will gently touch the surface of the cervix, and the cells will naturally fall off and adhere to it. The collected cell samples will be used for pathological examinations to screen for diseases such as cervical cancer.

[0003] In recent years, some technical services for women to collect cervical samples by themselves have emerged. The advantages of such products are convenience and privacy, but most women do not know what the cervix looks like or where it is. Women collect samples blindly and in fear, making it difficult to collect effective exfoliated cells. Due to the incomplete and inaccurate sampling, there is a greater risk of missing samples and damage.

[0004] CN116712110A discloses a disposable cervical sampling swab, comprising a sleeve of a hollow structure, a rotating rod is arranged inside the sleeve, the front end of the rotating rod is connected to the brush head, and the rear end is connected to the rotating handle, the length of the rotating rod is longer than the length of the sleeve, the diameter of the rotating handle is larger than the diameter of the sleeve, and the brush head can be driven to extend out of the sleeve or retract into the sleeve by pushing and pulling the rotating handle; the brush head can be driven to rotate by the rotating rod by rotating the rotating handle; a speculum is arranged on the inner wall of the sleeve or the rotating rod, and the speculum is connected to a data line for transmitting data. With the sampling swab, the examinee can operate independently under visual guidance, and can easily, accurately and painlessly send the sampling brush to the cervical position without using a gynecological expander, and rotate the small brush clockwise to fully brush effective exfoliated cells and tissues, thereby ensuring the accuracy of the detection, saving time and energy, and improving the convenience and reliability of cervical cancer screening.

[0005] However, the inventors found in the subsequent use process that the sampling swab disclosed in CN116712110A sometimes has problems such as the brush blocking the line of sight when in use, and can be further improved. Utility Model Content
