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

Connection pads for providing vacuum and fluid to a wound insert adapted to be in fluid communication with a wound, comprising:

• a fluid-delivery connection pad comprising a first body including a first domed cover having a dressing side and a connection side, the dressing side forming a first cavity having an upper portion and a base portion adapted to be disposed proximate a wound insert, and a first flange extending radially outward from the first domed cover and defining a terminus of the base portion, the first domed cover having a fluid lumen connection on the connection side configured to be coupled to a fluid source and having a fluid-delivery lumen on the dressing side extending from the fluid lumen connection and terminating proximate to the terminus for providing fluid to the wound insert;
• and
• a vacuum connection pad comprising a second body including a second domed cover having a dressing side and a connection side, the dressing side forming a second cavity having an upper portion and a base portion adapted to be disposed proximate a wound insert, and a second flange extending radially outward from the second domed cover and defining a terminus of the base portion, the second domed cover having a multi-lumen connection on the connection side configured to be coupled to a vacuum source and a pressure sensor, and having (a) a vacuum lumen on the dressing side terminating within the upper portion for providing a vacuum to the wound insert, and (b) a first pressure-sensor lumen on the dressing side extending from the multi-lumen connection and having an open end terminating proximate to the terminus, the open end including a lateral portion adjacent the open end having an opening extending into the base portion of the second cavity.
