Abstract
A device for draining wounds comprises an elongated catheter member having first and second lumens, an antibacteria filter received in communication with the second lumen adjacent the proximal end thereof and a check valve which is interposed between the proximal end of said second lumen and the filter. The distal end of the catheter member is receivable in a wound for draining the wound via suction applied to the proximal end of the first lumen, and a venting effect is provided by the second lumen through the filter and the check valve. The check valve prevents the backflow of liquids through the second catheter member into the filter to prevent the clogging thereof.
