Description

Household cervical screening cell sampling brush

The technical field is as follows:

the utility model relates to the technical field of medical equipment, concretely relates to family is from using cervical examination cell sample brush.

Background art:

china is a big country with cervical cancer, and newly published Chinese data in 2018 show 111,000 new cases of cervical cancer and 34,000 death cases of cervical cancer. The low cancer screening rate of cervical cancer is a main reason for high incidence, high late stage rate and high mortality of cervical cancer.

The conventional cervical cancer prevention screening can only be carried out in a hospital, and registration and queuing are required; the gynecological doctors take samples, the vaginal specula is needed, and most women are very frightened, painful and uncomfortable to use the vaginal specula. This is an important reason that the cervical cancer screening rate is very low in China. Especially for postmenopausal women, if vaginal bleeding and abnormal liquid drainage symptoms do not exist, patients do not go to hospitals basically to screen cervical cancer, and more postmenopausal women become cervical cancer target groups.

Cervical cell sampling screening is the important means that prevention cervical cancer takes place, the cervical brush is the cervical cell sampling apparatus of commonly used, at present, the collection work of cervical cell is gathered by medical staff of gynaecology and obstetrics usually, the mode of gathering is exactly to use the cervical brush to take a sample, traditional cervical brush simple structure function, and need use the vagina speculum earlier to strut the vagina, use the cervical brush again to brush the brush and wipe in order to take a sample to the cell department of cervix, patient's pain has not only been increased, the operation is also very inconvenient. Some types of cervical brushes can be directly inserted into the vagina to sample, and a patient can operate the cervical brushes by himself, but in the process of inserting the cervical brushes into the vagina, the brush bristles can firstly contact with cells on the vaginal wall and vaginal secretions, the cells at the cervix cannot be accurately sampled, the cells can be scraped off in the process of pulling out, the sampling number of the cervical cells is small, and the examination effect is influenced due to the interference of many other cells. Patent application number is ZL 201821479780.2's patent is through setting up the arc overhead gage on the opening that outer tube and screw thread form were arranged outside the cervical brush for when taking a sample to the gynaecology patient, can carry out the spiral and insert, realize the control of depth of insertion and dynamics, can effectually avoid inserting the discomfort that causes the people body or the soft vagina wall of fish tail, push out the cervical brush during the sample again. However, the width of the cervical brush with the structure is smaller than the diameter of the outer sleeve to ensure that the cervical brush can be retracted into the outer sleeve, the contact area between the cervical brush and the cervix is small, the sampling range is small, and the sampling accuracy is influenced; and the brush hair is required to rotate towards a specific direction during sampling so as to ensure that the brush hair is exposed out of the side wall of the outer sleeve for sampling, the correct sampling cannot be carried out due to the error of the rotating direction, and the use is troublesome.

The utility model has the following contents:

technical problem to be solved

The utility model aims at providing a family is from using cervical examination cell sample brush for the patient carries out cervical or vaginal cell sample by oneself, can improve the scope and the degree of accuracy of cell sample when guaranteeing smooth-going insert not arousing patient uncomfortable in the vagina, and it is little to solve current sampling device sampling range, the not high problem of the degree of accuracy of taking a sample.

The technical scheme is as follows:
