Disposable propellers are a common medical consumable used in the vaginal administration of vaginal gels and in the treatment of hemorrhoids. It is very easy to use, as it involves washing the vulva before use, putting on a disposable plastic sheath, and placing the medication to be pushed into the mouthpiece of the disposable pusher. The medication is administered in the squatting position or lying on the back, and the disposable propeller is inserted through the vaginal opening until it reaches the vaginal canal. Slowly squeeze the disposable propeller’s holding groove with your hand to push the medication into the body and then gently withdraw it. The disposable propellers are only good for one use and should not be used repeatedly to avoid infection. In addition, the plastic sheath that touches the disposable propellers should not be reused. When disposing of the disposable propellers, wrap the disposable propellers with the plastic sheath and place them in the trash.
