摘要：
A portable pump is provided for negative pressure wound therapy for drawing a vacuum from a wound site via a tube. The pump includes an inlet configured to attach the tube from the wound site； a canister in fluid communication with the inlet for collecting fluids drained from the wound site； and a manually-actuated pump mechanism for creating the vacuum. The pump mechanism includes a vacuum chamber in fluid communication with the canister； a piston disposed in the vacuum chamber； and a pump handle coupled to the piston to move the piston in the vacuum chamber between first and second positions to create the vacuum. The pump handle moving between a retracted position and an extended position. The piston is in the first position when said pump handle is in the retracted position and is in the second position when said pump handle is in the extended position.
