1. A negative pressure wound treatment system comprising:
- a conduit configured to deliver negative pressure to the wound from a source of negative pressure;
a suction adapter configured to deliver negative pressure to the wound, wherein the suction adapter comprises an elongate fluid channel having a proximal end and a distal end and an elongate 3D knitted or 3D fabric material extending between the proximal and distal ends; and
a connector configured to securely attach to a proximal portion of the 3D knitted or 3D fabric material, the connector comprising;
a hollow cylindrical body,a central channel extending through the body, andtwo distally extending projections, each projection further comprising at least one barb located thereon, the barbs configured to be pushed into and be retained within a proximal portion of the 3D knitted or 3D fabric material,wherein a proximal end of the body is configured to be press-fit with an inner or outer surface of the conduit to create a fluidic connection between the 3D knitted or 3D fabric material and the conduit.

Abstract
Disclosed herein are several embodiments of a reduced pressure appliance and methods of using the same in the treatment of wounds. Some embodiments are directed to improved fluidic connectors or suction adapters for connecting to a wound site, for example using softer, kink-free conformable suction adapters. Certain embodiments are directed to connectors used to connect fluid passage tube used in transmitting negative pressure to a fabric channel used in a suction adapter.

11. A connector for connecting a fluid passage tube to a fabric channel, comprising:
-
a body having a proximal end and a distal end; at least one member extending distally from the body, the at least one member configured to extend into the fabric channel; wherein the proximal end of the body is configured to be press-fit with an inner or outer surface of the fluid passage tube; and wherein the at least one member comprises at least one flexible line, and wherein the line comprises a tapered tip configured to loop through the fabric channel and be received in and securely connected to a cavity formed in the connector.

12. A negative pressure wound treatment system comprising:
-
a conduit configured to deliver negative pressure to the wound from a source of negative pressure; a suction adapter configured to deliver negative pressure to the wound, wherein the suction adapter comprises an elongate fluid channel having a proximal end and a distal end and an elongate 3D knitted or 3D fabric material extending between the proximal and distal ends; and a connector configured to create a fluidic connection between the 3D knitted or 3D fabric material and the conduit, the connector comprising two distally extending projections spaced apart from one another, each projection further comprising at least one barb located thereon, the barbs configured to be pushed into and be retained within a proximal portion of the 3D knitted or 3D fabric material. - View Dependent Claims (13)
