Sampling device for gynecological examination

Abstract

The invention discloses a sampling device for a gynecological examination. The sampling device comprises an outer cylinder and an inner cylinder which is nested in the outer cylinder and carries out axial sliding along the inner wall of the outer cylinder, wherein the inner cylinder is internally provided with a sampling device; when a sampling bag in the sampling device enters a human body to reach a sampling position, the sampling bag expands and shrinks along with the change of internal air pressure to guarantee that the sampling bag is in full contact with the human body during sampling isconducted; and after sampling is finished, the sampling bag is shrunk back to the inner cylinder to be separated from the human body. By use of the sampling device, the problem that sampling is difficult since a sample is liable to be polluted and a sampling brush is difficult in being contact with the human body in the prior art can be solved. In addition, the front end of the inner cylinder andthe front end of the outer cylinder are provided with a soft cover, so that the human body is only in contact with the soft cover in a process that the inner cylinder and the outer cylinder enter thehuman body, and the comfort level of a patient is improved. In addition, through a sliding block positioning device, a depth for the inner cylinder to enter the human body is controlled, and a function of sampling at different depths is realized. The sampling device has a simple structure, is accurate in sampling, is simple in operation and is high in practicality, and a small pain is caused forthe patient in a sampling process.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a sampling device for gynecological examination. Background technique [0002] Gynecological examination is a very common examination, mainly to check the conditions of vagina, cervix, uterus, fallopian tubes, ovaries, parauterine tissue and pelvic wall; the main function is to make early diagnosis, prevention and early treatment of some gynecological diseases; Periodic gynecological examinations can effectively prevent the occurrence of gynecological diseases, and during gynecological examinations, women's vaginal secretions or vaginal cavity will be extracted or inspected, so as to pass the secretion test and the vaginal wall and even the external reaction of the vagina The situation is better to observe the patient's condition; at present, different instruments are used to assist in the extraction or inspection of female vaginal secretions or vaginal cavity. In order to preven...

[0005] Aiming at the deficiencies of the prior art above, the object of the present invention is to provide a sampling device for gynecological examination. The inner cylinder which is nested inside the outer cylinder and slides axially along the inner wall of the outer cylinder enters the area to be tested. Sampling is carried out by the sampling device. When the sampling bag in the sampling device enters the human body to the sampling position, it expands and contracts with the change of internal air pressure to ensure full contact with the human body during sampling. After sampling, it shrinks i
