Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
As can be seen from fig. 1 to 5, the present invention includes 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 whose diameter is 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 first syringe 7 with an upward nipple end is disposed in the first vertical tube 3, the upper end of the first syringe 7 is communicated and fixed with the latex sleeve 5, a first piston handle 8, the lower extreme of first piston handle 8 is fixed with a stay cord 9, the lower extreme of stay cord 9 is worn out from the chassis center, the left and right sides in first standpipe 3 respectively is equipped with one and arranges the gasbag 10 of first standpipe 3 first half in, the left and right sides of disc 1 lower extreme respectively is equipped with the relative second cylinder 11 of nipple end, the nipple end of every second cylinder 11 is through hose and corresponding gasbag 10 intercommunication, be equipped with a second piston handle 12 in every second cylinder 11, press second piston handle 12 and can make and aerify and extrude 7 outer walls of first cylinder corresponding gasbag 10.
In order to place the first piston handle 8 to be separated from the first syringe 7, the lower end of the first syringe 7 is provided with a limiting block.
For the convenience of the operation of the device, a first pull ring 13 is fixed on the part of the pull rope 9 extending out of the lower end of the disc 1, and a second pull ring 14 capable of being sleeved on fingers is arranged at the outer end of each second piston handle 12.
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 tube 4 is taken down, the latex sleeve 5 is sleeved on the outer side of the first vertical tube 3, the first vertical tube 3 supports the latex sleeve 5, the upper end of the latex sleeve 5 is concave and is sunken in the first vertical tube 3, the first piston handle 8 is pushed to the uppermost position of the first needle cylinder 7, the two second pistons are pulled outwards to enable the two second needle cylinders 11 to contain gas, at the moment, the first needle cylinder 7 is arranged between the two air bags 10, the pull rope 9 penetrates through the disc 1 and is fixed through the first pull ring 13, the second vertical tube 4 is arranged on the disc 1, lubricating liquid is coated on the outer side of the second vertical tube 4, the device is held by hand, fingers are arranged in the two second pull rings 14 and extrude the two second piston handles 12 towards the middle, so that the gas in the two second needle cylinders 11 moves towards the corresponding air bags 10 and supports the corresponding air bags 10, at the moment, the first needle cylinder 7 is limited by the supported air bags 10, the device is filled in from the vagina of a patient, so that the upper end of the second vertical tube 4 abuts against the bottom of the vagina and is pressed tightly, the upper end concave position of the latex sleeve 5 is wrapped outside the cervix, the first pull ring 13 is pulled downwards under the state that the second piston handle 12 is kept to be pressed, the first pull ring 13 drives the pull rope 9 to enable the first piston handle 8 to move downwards, because the first syringe 7 is limited at the moment, the first syringe 7 is in a suction state when the first piston handle 8 is pulled, air in the concave part at the upper end of the latex sleeve 5 is sucked into the first syringe 7, at the moment, because the second vertical tube 4 abuts against the bottom of the vagina, outside air cannot enter the latex sleeve 5, the negative pressure is increased when the first syringe 7 is sucked, the latex sleeve 5 is attached to the outer wall of the cervix, along with the increase of the negative pressure, the latex sleeve 5 is attached to the outer side of the cervix tightly, and viscose on the cervix and the like are adsorbed into the first syringe 7, after mucus suction is finished, the two second piston handles 12 are loosened to enable the air bag 10 to be free from inflation and expansion, at the moment, the first needle cylinder 7 is not bound any more, the pull rope 9 is pulled to enable the latex sleeve 5 to be wrapped to the cervix in an inward turning mode, the latex sleeve 5 can automatically retract and wrap the cervix after being separated from the upper end of the first vertical pipe 3, the annular bulge on the latex sleeve 5 scratches and rubs cells on the outer wall of the cervix, and therefore 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 negative pressure increase in emulsion cover 5 is realized to the suction of the first cylinder 7 of cooperation to realize that cyclic annular 6 in the emulsion cover 5 carries out abundant sample with cervix epithelial cell, and this sampling process wall tradition brush cotton swab sample is safe and reliable more, can not cause the secondary injury.
2. This device need cause the negative pressure at the front end of cervix through the suction of first cylinder 7 before using, adnexed mucus suction comes out and adsorbs to first cylinder 7 on this in-process can effectual processing cervix, the mucus has been cleared up when using latex cover 5 sampling afterwards, make the littleer sampling effect of latex cover 5 sampling process impurity better, paint lubricated liquid in the outside of second standpipe 4 simultaneously, lubricated liquid does not contact with latex 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.
