The proper installation method of uterine tray mainly includes position, sterilization treatment, placing uterine tray and abdominal pressure test. The uterine tray is a special device for treating mild uterine prolapse and is generally only suitable for patients with mild prolapse. For moderate to severe uterine prolapse, uterine tray is less effective and surgery is usually an option. The correct installation method of uterine tray mainly includes the following points: 1. Positioning: female patients need to lie flat on the bed and bend their legs apart at the knees. 2. Sterilization: the female patient needs to clean and sterilize the perineum according to the method of aseptic operation. 3. Insert the uterine tray: separate the labia majora and minora of the female patient, sterilize the inner part of the labia minora and the inner part of the vagina, and in the sterile state of the vagina, send the uterine tray into the vagina in a slanting position to reach the inner part of the pubic arch. 4. Abdominal pressure test: After the uterine tray is inserted, it is necessary to perform moderate squatting and standing up activities to perform an abdominal pressure test to clarify whether the uterine tray has been dislodged. It is recommended that female patients go to the hospital in time if necessary, under the guidance of obstetricians and gynecologists for the application of uterine support.
