Problems solved by technology

[0005] Aiming at the above-mentioned shortcomings existing in the prior art, the present invention provides a multifunctional double-chamber balloon cervical dilator for obstetrics and gynecology, which solves the problem of the inconvenient control of the external expansion of the current cervical dilator during use and the inability to carry out repeated training. , when the cervical dilator is used, the dilator is misplaced due to the internal secretion of the user's cervix and the muscle contraction of the cervix, and it is inconvenient to remove the cervical dilator when using the cervical dilator.

Abstract

The invention relates to the technical field of medical instruments, in particular to a clinical multifunctional double-cavity air bag cervical dilator for the obstetrics and gynecology department, which comprises a dilator main rod, an elastic empty bag is glued on the surface of the dilator main rod, a fixing mechanism is mounted on the surface of the dilator main rod, and a liquid suction and injection mechanism is mounted on the top of the dilator main rod. Air storage bins are annularly and fixedly connected to the interior of the expander main rod at equal intervals, and piston pieces are symmetrically hinged to the surfaces of the air storage bins. When the cervical dilator is used, liquid in the cervix uteri can be drained according to the actual operation requirement, so that the situation that the dilator is dislocated and slides due to too much secretions in the cervix uteri is avoided, meanwhile, the part of the structure can be used as a liquid injection device, and the cervical dilator is different from an old-fashioned cervical dilator. The dilator can carry out multi-gear cervical dilation and can automatically reset in the dilation process, and therefore elasticity training is carried out on the cervix through repeated dilation and contraction.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a multifunctional double-chamber airbag cervical dilator for obstetrics and gynecology clinics. Background technique [0002] Cervical dilator is a common instrument used by gynecologists to examine the cervix. After the dilator in the shape of a duckbill stretches the vagina, the cervix can be clearly seen. It is used to check the diagnosis or treatment of cervical erosion and inflammation. I hope to help you, and now there is a balloon type cervical dilator, its main function is as a cervical dilation exercise, used for medical examination or cervical pre-dilation before abortion. [0003] However, this cervical dilator cannot properly adjust the expansion diameter when used, and repeated training cannot be performed, which may cause skin tearing in the uterus. At the same time, due to the use of the dilator, the user may be accompanied by secretions These secretion...
