The proper way to use corkscrew for pregnant women is to lubricate the anal opening with an appropriate amount of corkscrew, then insert the catheter into the anus and squeeze all of the medicine in. 1. Pregnant women can carefully bend over to remove their pants to their knees and lie on their side with their hips on the side of the bed. 2. Squeeze out an appropriate amount of medication to lubricate the anal opening, then insert the thin tube portion of the corkscrew into the anus and squeeze the corkscrew to get all of the medication into the rectum. 3. After pulling out the corkscrew, you can use paper towels to press the anus and keep it there for a while, so that the medication can act in the anus for a longer period of time. 4. When a pregnant woman has an obvious urge to have a bowel movement, go to the toilet immediately to have a bowel movement. If you need to use corkscrew, please use it under the guidance of your doctor.
