This enema plug has a rubber tube running through it. Fluids can pass through while it is inflated! Once the plug is inserted in the and inflated, the large rubber hose can be hooked to an enema bag. When the time comes to administer the enema, the fluid will flow through the enema plug into the colon. The inflatable plug prevents pushing out the plug and the enema until the desired time arrives. Easy to clean and made to last.
