Multiple-wound negative pressure wound therapy using multiple fluid collection volumes

A negative pressure wound therapy system for treating multiple wounds on a patient's body, the system comprising:

• a source of negative air pressure;
• an air source;
• a fluid collection volume;
• a first wound-covering dome configured to be disposed over a first wound on the patient's body;
• and
• a second wound-covering dome configured to be disposed over a second wound on the patient's body,
• wherein the source of negative air pressure is in fluid communication with the fluid collection volume, the fluid collection volume is in fluid communication with the first wound-covering dome, the first wound-covering dome is in fluid communication with the second wound-covering dome, and the second wound-covering dome is in fluid communication with the air source, and
• wherein the source of negative air pressure, the fluid collection volume, the first wound-covering dome, the second wound-covering dome, and the air source are fluidly connected in series.

A fluid collection canister for use in a negative pressure wound therapy system for treating multiple wounds on a patient's body, the fluid collection canister comprising:

• a first fluid collection volume disposed within the fluid collection canister, first fluid collection volume having:
• a first inlet port configured to be in fluid communication with a first wound-covering dome;
• and
• a first outlet port configured to be in fluid communication with a source of negative air pressure;
• a second fluid collection volume disposed within the fluid collection canister, second fluid collection volume having:
• a second inlet port configured to be in fluid communication with a second wound-covering dome;
• and
• a second outlet port configured to be in fluid communication with the source of negative air pressure;
• and
• a wall disposed within the fluid collection canister separating the first fluid collection volume and the second fluid collection volume.
