valved drainage device

A valved drainage device is a medical tool used to regulate the flow of fluids, such as cerebrospinal fluid or other bodily fluids, from one area of the body to another. It features a built-in valve that controls how much fluid is released, preventing over-drainage or under-drainage. These devices are commonly used to treat conditions like hydrocephalus or to relieve pressure after surgery. The valve ensures a steady, controlled drainage, helping to maintain normal pressure and prevent complications associated with fluid buildup.
