As can be seen from fig. 1 to 5, the present invention comprises a disc 1, two annular grooves 2 coaxial with the disc 1 are disposed on the upper end surface of the disc 1, a first vertical tube 3 is detachably inserted into the annular groove 2 on the inner side, a second vertical tube 4 is detachably inserted into the annular groove 2 on the outer side, a space is present between the first vertical tube 3 and the second vertical tube 4, the upper end of the second vertical tube 4 is higher than the upper end of the first vertical tube 3, a latex sleeve 5 having a diameter smaller than that of the first vertical tube 3 in a natural state is sleeved on the outer end of the first vertical tube 3, the latex sleeve 5 is sleeved on the first vertical tube 3 and is supported by the first vertical tube 3, a plurality of annular protrusions 6 are uniformly distributed on the outer edge surface of the latex sleeve 5 at intervals along the axial direction thereof, a syringe 7 having an upward nipple end is disposed in the first vertical tube 3, the upper end of the syringe 7 is communicated and fixed with the latex sleeve 5, a piston handle 8 is disposed in the syringe 7, the lower extreme of stay cord 9 is worn out from the chassis center, and the left and right sides in the first standpipe 3 respectively is fixed with an arc backup pad 10 that the opening is relative, and cylinder 7 can pass through from the centre of two arc backup pads 10, and the below of every arc backup pad 10 is equipped with a first permanent magnet 11, and the left and right sides of the lower extreme opening part of cylinder 7 respectively is equipped with a second permanent magnet 12, and first permanent magnet 11 and second permanent magnet 12 can adsorb each other.
In order to prevent the piston handle 8 from separating from the needle cylinder 7, the lower end of the needle cylinder 7 is provided with a baffle disc 13, and the piston can pass through the middle channel of the baffle disc 13.
To facilitate the operation of the device, a pull ring 14 is fixed to the portion of the pull cord 9 extending beyond the lower end of the disc 1.
In order to facilitate the use of the device, the upper end of the first vertical pipe 3 and the upper end of the second vertical pipe 4 are in cambered surface transition.
The specific working process of the invention is as follows: when the device is used, the second vertical pipe 4 is taken down, the latex sleeve 5 is sleeved on the outer side of the first vertical pipe 3, the first vertical pipe 3 supports the latex sleeve 5, the upper end of the latex sleeve 5 is concave and sunken in the first vertical pipe 3, the piston handle 8 is pushed to the uppermost position of the needle cylinder 7, the needle cylinder 7 penetrates from the lower end of the arc-shaped supporting plate 10 and enables the second permanent magnets 11 and the two second permanent magnets 12 to attract each other, the pull rope 9 penetrates through the disc 1 and is fixed through the pull ring 14, the second vertical pipe 4 is installed on the disc 1, lubricating liquid is smeared on the outer side of the second vertical pipe 4, the device is held by a hand and filled in from the vagina of a patient, the upper end of the second vertical pipe 4 is abutted against the bottom of the vagina and is pressed, the sunken position of the upper end of the latex sleeve 5 is wrapped on the outer side of the cervix, the pull ring 14 is pulled downwards, at the moment, under the adsorption effect of the first, the syringe 7 is limited, the pull ring 14 drives the pull rope 9 to enable the piston handle 8 to move downwards, the syringe 7 is limited at the moment, the syringe 7 is in a suction state when the piston handle 8 is pulled, air in the concave part at the upper end of the latex sleeve 5 is sucked into the syringe 7, at the moment, the bottom of the vagina is propped against the bottom of the vagina by the second vertical tube 4, so that outside air cannot enter the latex sleeve 5, negative pressure is increased when the syringe 7 is sucked, attachment of the latex sleeve 5 towards the outer wall of the cervix is achieved, the latex sleeve 5 is more tightened when being attached to the outer side of the cervix along with increase of the negative pressure, mucus on the cervix and the like are adsorbed into the syringe 7 at the moment, along with gradual increase of the pulling force, the negative pressure in the syringe 7 is increased, when the adsorption force between the first permanent magnet 11 and the second permanent magnet 12 is not enough to resist the pulling force of the pull rope 9, the pull rope 9 is pulled to enable the latex sleeve 5 to wrap the cervix in an inward-turning manner, the latex sleeve 5 can automatically retract and wrap the cervix after being separated from the upper end of the first vertical pipe 3, and the annular bulge on the latex sleeve 5 scrapes and rubs cells on the outer wall of the cervix, so that sampling of epithelial cells of the cervix is achieved.
Compared with the traditional equipment, the device has the following advantages:
1. the sampling process of this device can contract automatically through the emulsion cover 5 that is propped up after breaking away from first standpipe 3, and this retraction process can realize that emulsion cover 5 is close to and wraps up in the outside of cervix, and the suction of cooperation cylinder 7 realizes the negative pressure increase in emulsion cover 5 to realize that cyclic annular 6 in the emulsion cover 5 carries out abundant sample with cervix epithelial cell, this sampling process wall tradition brush cotton swab sample safe and reliable more, can not cause the secondary damage.
2. This device need lead to the fact the negative pressure at the front end of cervix through the suction of cylinder 7 before using, adnexed mucus suction comes out and adsorbs to cylinder 7 on this in-process can effectual processing cervix, the mucus has been cleared up when using 5 samplings of emulsion cover afterwards for the less sampling effect of 5 sampling process impurities of emulsion cover is better, paint lubricated liquid in the outside of second standpipe 4 simultaneously, lubricated liquid does not contact with emulsion cover 5 all the time, the impurity of sampling has also been reduced equally.
3. This device also can realize being operated by the person of sampling at the in-process of sampling by oneself, whole process easy operation, and the patient has more self impression and carries out gradual operation, reduces the patient and steps on the psychological pressure among the sampling process for the sampling is scientific more and has hommization.
The cervical cell sampler is novel in concept, ingenious in structure and strong in practicability, and effectively solves the problems that in the existing cervical cell sampling process, the sampling means is rough, bleeding of a patient is easily caused, sampling is inaccurate, and psychological pressure of the patient is high.
