Negative pressure wound therapy canister connection system

A canister for connecting to a pump unit of a negative pressure wound therapy system, the canister comprising:

• a canister connection wall having a first side, a second side, and at least a first aperture and a second aperture disposed between the first side and the second side of the canister connection wall;
• a first pump engaging mechanism disposed adjacent the first side of the canister connection wall for removably engaging a first canister engaging mechanism disposed adjacent a first side of a pump connection wall of the pump unit;
• and
• a second pump engaging mechanism disposed adjacent the second side of the canister connection wall for removably engaging a second canister engaging mechanism disposed adjacent a second side of the pump connection wall of the pump unit,
• wherein, when the first pump engaging mechanism engages the first canister engaging mechanism and the second pump engaging mechanism engages the second canister engaging mechanism, the canister is substantially fluidly sealed to the pump unit, the first aperture is fluidly coupled to a pump inlet port disposed between the first side and the second side of the pump connection wall, and the second aperture is fluidly coupled to an outlet port of the pump unit disposed between the first side and the second side of the pump connection wall.

A method for connecting a canister to a pump connection wall of a pump unit of a negative pressure wound therapy system, the method comprising:

• providing an attachment fixture for removably connecting to the pump connection wall of the pump unit, the pump connection wall having a first side, a second side, and at least a pump inlet port disposed between the first side and the second side, the attachment fixture including a first end, a second end, a first canister engaging mechanism disposed adjacent the first end of the attachment fixture, and a second canister engaging mechanism disposed adjacent the second end of the attachment fixture;
• providing a canister including:
• a canister connection wall having a first side, a second side, and at least a first aperture disposed between the first side and the second side of the canister connection wall,
• a first pump engaging mechanism disposed adjacent the first side of the canister connection wall, and
• a second pump engaging mechanism disposed adjacent the second side of the canister connection wall;
• connecting the attachment fixture to the pump connection wall of the pump unit such that the attachment fixture extends from the first side of the pump connection wall to the second side of the pump connection wall with the first end disposed adjacent the first side of the pump connection wall and the second end disposed adjacent the second side of the pump connection wall;
• engaging the first pump engaging mechanism of the canister with the first canister engaging mechanism disposed adjacent the first side of the pump connection wall such that the first aperture of the canister connection wall is aligned with the pump inlet port of the pump unit;
• and
• engaging the second pump engaging mechanism of the canister with the second canister engaging mechanism disposed adjacent the second side of the pump connection wall for removably connecting the canister to the pump unit such that canister is substantially fluidly sealed to the pump unit and the first aperture of the canister connection wall is fluidly coupled to the pump inlet port of the pump unit.
