Description

Vaginal dilator with self-contained light source

technical field

The invention relates to the technical field of medical devices, in particular to a vaginal dilator with a light source.

Background technique

At present, disposable vaginal dilators are all used in clinical gynecological examinations, routine treatments and contraceptive measures. Existing vaginal dilators are usually a thin duckbill clip. The doctor places it in the patient's vagina and opens the entire clip, and then observes the patient's vaginal wall and cervix with the help of an external light source such as a gynecological examination lamp. However, the gynecological examination lamp is large. If it is placed in front of the doctor, it will easily block the doctor's line of sight. If it is placed behind the doctor, the doctor's hands or head will block the light and form a dark shadow, making it impossible to fully and clearly observe the lesion, which will affect the accuracy of the doctor's diagnosis. rate, prolong the diagnosis time, and increase the suffering of patients.

In addition, the lamp shell and lamp pole of gynecological examination lamps are mostly made of iron, which is easy to rust after long-term use. When doctors adjust the angle of the lamp by hand, rust will inevitably stick to the disposable gloves they wear, which is not conducive to gynecological asepsis. examine.
