When the toothbrush is used, the support ring 903 is arranged on the right ring frame 102, and the brush handle 901 is pulled to enable the brush head 902 to be close to the position of the support ring 903; the device is moved by holding the handrail 17, so that the left end of the roller frame 2 is aligned with the vulva of the patient, and then the handrail 17 is slightly pushed to enable the left end of the roller frame 2 to enter the vagina of the patient until the silica gel pad 18 is propped against the vulva of the patient; the handrail 17 is stabilized and the push handle 16 is pushed to enable the roller frame 2 to move towards the interior of the vagina, the rubber sleeve 8 is unfolded from inside to outside under the pushing action of the roller frame 2 and is flatly paved on the vaginal wall, the friction force between the silica gel sleeve 8 and the roller frame 2 is obviously reduced by the rolling of the roller 3, the roller frame 2 is facilitated to advance, the silica gel sleeve 8 isolates the roller frame 2 from the vaginal wall, so the roller frame 2 is not in direct contact and friction with the vaginal wall, and meanwhile, the rubber sleeve 8 is pushed into the flatly paved entering mode to enable the rubber sleeve 8 to not rub with the vaginal wall, so that the possibility of injury of an instrument to the vaginal wall can be prevented, and the astringency and pain caused by the friction between the instrument and the vaginal wall can be effectively avoided; in the process of spreading and unfolding the rubber sleeve 8, the length of the rubber sleeve 8 is fixed, so that the right end of the rubber sleeve 8 moves in the same direction along with the movement of the roller frame 2, the inner ring 4 is pulled to slide in the same direction, the tension spring 15 generates extension deformation, the rubber sleeve 8 is always kept in a tightened state under the action of the tension force of the tension spring 15 and the elastic force of the rubber sleeve 8, and the phenomenon that the pushing of the roller frame 2 is influenced by the stacking of the loosened rubber sleeve 8 and the discomfort brought to a patient is avoided.

When the left end of the roller frame 2 enters the cervical orifice, the push handle 16 is stopped to push and the brush handle 901 is pushed to enable the brush head 902 to enter the cervical orifice to finish sampling, and in the process of entering the brush head 902, as the roller frame 2 completely props the vagina, the brush head 902 cannot be contacted with any part of the vagina, thereby effectively avoiding the influence of vaginal secretion on the sampling inspection result.

After sampling is finished, the supporting ring 903 is taken down after the brush handle 901 is pulled out, and then the sampling brush 9 is taken out, so that the next operation is convenient to carry out; the roller frame 2 is pulled outwards, the inner ring 4 continuously slides outwards under the action of the tension spring 15, and the rubber sleeve 8 is retracted and reset; when the roller frame 2 is completely reset, the device is drawn out of the vagina by slightly pulling the handrail 17.

Because only the rubber sleeve 8, the sampling brush 9 and the silica gel pad 18 are in contact with a human body in the using process, the parts can be repeatedly used after being replaced, and unnecessary resource waste can be effectively reduced.

The invention utilizes the flexible extension of the rubber sleeve to ensure that the patient does not directly contact with a hard instrument, thereby effectively reducing the injury possibly brought by the use of the instrument; when the roller frame is inserted, the rubber sleeve is gradually tiled and unfolded and does not generate sliding friction with a human body, the friction force between the rubber sleeve and the roller frame is very small due to the rolling of the roller, the inserting operation can be completed without using lubricating liquid, the sense and the pain of the appliance and the human body due to friction are eliminated, the allergic hidden danger of the lubricating liquid contacting with the human body in a large area can be eliminated, meanwhile, the lubricating liquid does not exist in the vagina, and the private part of a patient is cleaned very conveniently after sampling.

When the sampling brush is used for sampling and checking, no matter in the inserting process of the roller frame or in the in-out process of the sampling brush, the vagina is propped by the roller frame, so that the sampling brush is not in direct contact with other human tissues such as vulva or vaginal wall all the time, the sampling sample is real and accurate, secondary pollution is avoided, and the influence on the checking result caused by adhesion of other secretions of a human body on the sampling brush is effectively avoided.

In addition, the rubber sleeve, the sampling brush, the guard plate and the silica gel pad are convenient and quick to detach and replace, can be repeatedly used after being replaced, are sanitary and environment-friendly, and save resources.
