Patent ID: 7678102

Claim:
A negative pressure therapy apparatus, comprising: a porous pad; a source of reduced pressure; a pressure sensor; a first section of multi-lumen suction tube having a first end fluidly connected to the porous pad; a second section of multi-lumen suction tube having a central lumen fluidly connected to the source of reduced pressure, and a peripheral lumen fluidly connected to the pressure sensor; a first connector half attached to a first end of the second section of tubing, the first connector half having a central projection extending beyond the first end of the second section of tubing and dimensioned to enter a central lumen of the first section of tubing, a recess peripheral to the central projection, and passages that communicate at a first end with the peripheral lumen of the second section of multi-lumen suction tube and at a second end with the recess; an o-ring within the recess; and a second connector half attached to a second end of the first section of tubing, the second connector half having a shoulder adapted to enter the recess and seal against the o-ring without obstructing the second end of the passages in the first connector half so that the central lumen is in fluid communication with the central lumen of the first section of multi-lumen suction tube and the peripheral lumen of the second section of multi-lumen suction tube is in fluid communication with a peripheral lumen of the first section of multi-lumen suction tube.
