Technical Field

[0001] The utility model relates to the clinical field of obstetrics and gynecology, in particular to a vaginal sterilization device for preventing backflow. Background Art

[0002] Nowadays, more and more women suffer from gynecological inflammation to varying degrees. The main manifestations of gynecological inflammation are usually abnormal leucorrhea, odor, and itching. This type of disease has seriously affected women's physical and mental health. Women with gynecological inflammation generally need to use vaginal sterilization devices.

[0003] The common vaginal sterilization device currently has a relatively simple structure, which consists of a liquid storage tank, a piston rod and a piston. The piston rod is controlled to make the piston spray the liquid medicine inside the vagina to achieve a sterilization effect. However, since there is no extension device, the length of the device cannot be adjusted. In addition, the nozzle of the ordinary vaginal sterilization device cannot be replaced, so the nozzle needs to be cleaned and disinfected after use before it can be used again, which seriously affects work efficiency.

[0004] Therefore, those skilled in the art provide a backflow-proof vaginal sterilization device to solve the problems raised in the above background technology. Utility Model Content
