Abstract: A bulb evacuator is provided for closed wound suction having a flexible compressible container with a pair of inlets having one way valves therein and a port to a suction source with a removable cap thereon at one end of the bulb evacuator. The opposite end of the bulb evacuator is provided with an integrally formed anti-reflux valve and a latching device surrounding the anti-reflux valve. A separate collection bag can be attached to the latching device so that when the bulb evacuator is filled with fluid from a closed wound, it can be compressed to force the fluid into the attached collection chamber and simultaneously creating a suction within the bulb evacuator to promote further withdrawal of fluids from the closed wound.

Abstract: A closed system method and apparatus for removing collected liquid from a portable closed wound suction drainage device which reduces the potential contamination of the drainage device and cross infection from the use of the drainage device is disclosed. A disposable collection bag is attached to the outlet (emptying port) of the drainage device and the contents are transferred in a closed system procedure into this collection bag through a one-way inlet. After transferring the contents, the filled collection bag is removed from the outlet and capped for subsequent disposal, and a new collection bag is attached to the outlet of the drainage device. Preferably, the collection bag is compacted, such as by rolling, and held in this compact form by a retainer. A protective closure cap is provided for the inlet of the collection bag to form a cover and seal for the inlet both before fitment to the device and after filling.
