If you are dealing with multiple wounds, you can use a "Y" adaptor to connect two wounds to one NPWT wound vacuum pump. All you need is a small bore plastic "Y". Connect the two connection tubes from the dressings to the legs of the "Y", and connect the tube from the canister to the body of the "Y". To prevent cross-contamination between the two wound beds, some "Y" connectors built especially for negative pressure wound therapy incorporate one-way valves. We stock the Pensar Basic Series "Y" Connector.
