Description

Insertable vaginal disinfector

Technical Field

The utility model belongs to the technical field of medical equipment, in particular to an insertable vaginal disinfector.

Background Art

When performing vaginal disinfection care on patients in obstetrics and gynecology, the conventional disinfection method is to use a vaginal dilator to stretch the vagina, then insert a medical cotton swab or cotton ball dipped in disinfectant into the patient's vagina, and wipe the vagina with the disinfectant. The above vaginal disinfection method is likely to make the patient feel uncomfortable, and even the fibers of the medical cotton swab or cotton ball are likely to remain on the inner wall of the vagina.

In addition, there is also an existing technology that uses an insertion-type vaginal disinfection method, in which a cannula with one end closed is inserted into the vagina, a plurality of liquid outlet holes are opened on the side wall of the cannula, a dropper is installed at the other end of the cannula, and the liquid outlet end of the dropper extends into the interior of the cannula, and the liquid in the dropper enters the cannula and enters the patient's vagina from each liquid outlet hole by squeezing the rubber nipple of the dropper, thereby disinfecting the vagina. During use of the disinfector used in the above-mentioned vaginal disinfection method, the liquid in the dropper must first enter the cannula, and then flow out from each liquid outlet hole on the side wall of the cannula, which easily causes a large amount of disinfectant to be retained in the cannula, resulting in a waste of disinfectant; in addition, it is also easy for the liquid outlet holes at various locations on the side wall of the cannula to discharge unevenly, resulting in uneven drug delivery to the inner wall of the vagina, affecting the effect of vaginal disinfection.
