Apparatuses and methods for negative pressure wound therapy

A connector device for a negative pressure wound therapy system, the connector device comprising:

• a connector housing,
• a fluid outlet connected to a first side of the connector housing,
• an air feeding port and an air filter on the first side of the connector housing, and
• a coupling on a second side of the connector housing, the second side opposite the first side of the connector housing;
• wherein:
• the fluid outlet is configured to be releasably connected to a negative pressure source,
• the coupling is configured to engage the connector device with a wound side connector of a wound side assembly,
• the wound side assembly comprises the wound side connector having a fluid removing conduit with a first side port along a first center axis and an air supplying conduit with a second side port along a second axis parallel to the first axis, and
• the connector device is configured such that when the coupling is engaged with said wound side connector, said fluid removing conduit is fluidly connected to the fluid outlet, and the air supplying conduit is fluidly connected to the air feeding port such that air ambient of the connector device can be fed to the air supplying conduit via the air filter and the air feeding port.

A connector system for a negative pressure wound therapy system, the connector system comprising:

• a connector device comprising a connector housing, a fluid outlet, an air feeding port, an air filter on a first side of the connector housing, and a coupling on a second opposite side of the housing, the coupling comprising a first barbed connector and a second barbed connector parallel to the first barbed connector;
• and
• a wound side assembly comprising a wound side coupling comprising a first aperture and a second aperture parallel to the first aperture, wherein the first and second apertures are spaced apart and separated by a wall of the wound side assembly,
• wherein:
• the fluid outlet is configured to be connected to a negative pressure source;
• the first barbed connector is configured to be engaged with the first aperture of the wound side coupling and the second barbed connector is configured to be engaged with the second aperture of the wound side coupling, the wound side assembly further comprising a fluid removing conduit with a portion connected to the wound side coupling and an air supplying conduit with a portion connected to the wound side coupling;
• and
• the connector device is configured such that when the connector device is engaged with said wound side coupling, said fluid removing conduit is fluidly connected to the fluid outlet, and the air supplying conduit is fluidly connected to the air feeding port such that air ambient of the connector device can be fed to the air supplying conduit via the air filter and the air feeding port.
