Negative Pressure Wound Therapy Apparatus Including a Fluid Line Coupling

A negative pressure wound therapy apparatus comprising:

• a wound dressing for defining a reservoir over a wound in which a negative pressure may be maintained by forming a substantially fluid-tight seal around the wound;
• a fluid conduit in fluid communication with the reservoir and defining a fluid flow path for carrying fluids from the reservoir;
• a vacuum source in fluid communication with the fluid conduit, the vacuum source suitable for providing an appropriate negative pressure to the reservoir to stimulate healing of the wound;
• and
• a fluid line coupling, in line with the fluid conduit, the fluid line coupling comprising first and second coupling segments adapted for selectable engagement and disengagement, wherein the at least one of the first and second coupling segments is capable of obstructing fluid flow further includes a post having a bias to deform the fluid conduit section coupled thereto upon disengagement from the other of the first and second coupling segments to obstruct fluid flow, and further wherein the other of the first and second coupling segments includes a pin adapted to engage the post when first and second coupling segments are engaged such that the post is moved against the bias to allow the fluid conduit section to assume an un-deformed shape to permit fluid flow there through.
