The invention discloses a portable perineum cleaning device for obstetric care, and relates to the field of perineal cleaning. Aiming at the problems that when a cleaning tube is inserted into a vagina to clean the vagina, due to the small diameter of the cleaning tube, bacteria or secretion residues are left between the front and back vaginal fornices and folds, so that disinfection and cleaningare incomplete, the treatment effect of diseases is reduced, and the cleaning efficiency is low, in addition, when the vagina is cleaned by using the current cleaning tube, the cleaning tube often scratches the inner wall of the vagina to cause cross-infection, so that the pain of patients is increased, and the current cleaning tube has lower safety performance, the invention proposes the following solution: the device includes a shell, a cleaning liquid storage tank is welded to the left end of the shell, and sterilization lamps are welded to the top and bottom inner walls of the shell. The device has a simple structure and novel design, the cleaning device can be sterilized and disinfected to prevent cross infection, and the device can avoid damage to the patient vagina in the cleaning process, reduces patient discomfort, and is convenient to use, high in practicability, and suitable for widespread promotion.
