Wound-connection pads for fluid instillation and negative pressure wound therapy, and systems and methods

A vacuum and fluid-delivery connection pad for providing a vacuum and fluid to a wound insert adapted to be disposed in a sealed space in fluid communication with a wound, comprising:

• a body having a dressing side and a connection side, the dressing side including a surface defining a cavity having an upper portion and a base portion adapted to be disposed proximate the wound insert;
• and
• a flange surrounding the base portion of the cavity, the flange being substantially planar and having a lower surface defining a terminus of the base portion of the cavity;
• and
• wherein the connection side includes (i) a single-lumen connection configured to be coupled to a fluid source and having a fluid-delivery lumen extending through the cavity proximate the terminus of the base portion and configured to abut and be in fluid communication with the wound insert, and (ii) a multi-lumen connection configured to be coupled to a vacuum source and a pressure sensor, the multi-lumen connection having (a) a vacuum lumen terminating within the upper portion of the cavity for providing a vacuum within the cavity for the wound insert, and (b) a first pressure-sensor lumen having an open end configured to extend into the base portion of the cavity and a lateral portion adjacent the open end having an opening extending into the base portion of the cavity.
