Experience the freedom of movement with our Heimlich-type Pneumovent drainage valves. Designed for your comfort and convenience, these small one-way valves prevent the return of gas or fluid into the pleural cavity, making patient ambulation a breeze. Walk with ease, simply by carrying the bag that channels water from the valve. The drying process of the pleural cavity is now safe, simple, and efficient. Embrace a new level of comfort with Pneumovent.
