Orientation independent canister for a negative pressure wound therapy device

A canister assembly for a negative pressure wound therapy system and fluidly connectable to a dressing assembly, the canister assembly comprising:

• a first canister wall;
• a second canister wall opposite the first canister wall,
• a chamber;
• a canister interface at least partially defining a portion of the chamber, the canister interface having a negative pressure port thereon and in fluid communication with the chamber;
• a first filter at least partially defining a first side of the chamber;
• and
• a second filter at least partially defining a second side of the chamber, opposite the first side of the chamber,
• wherein the first filter and the first canister wall at least partially define a first fluid path therebetween, the first fluid path providing fluid communication between the chamber and the negative pressure port, and
• wherein the second filter and the second canister wall at least partially define a second fluid path therebetween, the second fluid path providing fluid communication between the chamber and the negative pressure port.

A method for assembling a canister for use with a portable negative pressure wound therapy system, the method comprising:

• providing a canister having at least a first canister wall and a second canister wall opposite the first canister wall;
• disposing a first filter adjacent the first canister wall to define a first passageway;
• disposing a second filter adjacent the second canister wall to define a second passageway;
• and
• disposing a canister interface having a negative pressure port thereon in the canister,
• wherein the canister includes a chamber defined by the first filter, the second filter, and the canister interface,
• wherein the first filter and the first canister wall at least partially define a first fluid path therebetween, the first fluid path providing fluid communication between the chamber and the negative pressure port, and
• wherein the second filter and the second canister wall at least partially define a second fluid path therebetween, the second fluid path providing fluid communication between the chamber and the negative pressure port.
