The Prelude offers a new approach to internal cleansing, introducing the option of single or multiple low-volume on-site rinses. This method is not feasible with traditional enemas, as they discharge too quickly. The Prelude addresses this through a special one-way valve, slow flow that slows the flow of the liquid and prevents the bulb from ballooning with air. The valve also ensures hygienic operation, preventing the recycling of the liquid back to the bulb. The Prelude makes this process possible, providing an easier, quicker, and more comfortable cleaning experience.
