Abstract

An apparatus and method are disclosed for providing a fluid communication path to a wound site through a drape. The apparatus comprises a body portion having a lower surface and an upper surface, at least one connection port, at least one suction port and at least one fluid communication passageway between the connection port and the suction port. A connector at an end of at least one tubular conduit is locatable through the drape into an orifice in the connection port to thereby provide a fluid communication path through the drape between the tubular conduit and the wound site.

First claim

What is claimed is:

1 . A negative pressure wound therapy apparatus comprising:
a body configured to be positioned at a wound facing side of a drape, a connector configured to be at least partially positioned at a non-wound facing side of the drape opposite the wound facing side, the connector comprising:
a snap fit element for attaching the connector to the body; and
a passageway configured to be fluidically connected to a negative pressure source;
wherein the body and the connector are configured to be attached to each other with the drape positioned therebetween, wherein the snap fit element of the connector is configured to be attached to the body by pushing the connector towards the body in a direction that is substantially parallel to a wound site, and wherein the passageway of the connector is configured to provide negative pressure to the wound site under the drape through the body when the body and the connector are attached to each other.

2 . The negative pressure wound therapy apparatus according to claim 1 , wherein the body comprises an orifice configured to receive the connector and a chamber extending from the orifice.

3 . The negative pressure wound therapy apparatus according to claim 1 , wherein the connector further comprises a mouth region configured to be urged within the chamber.

4 . The negative pressure wound therapy apparatus according to claim 1 , wherein the connector further comprises a piercing tip configured to thrust through the drape into the body.

5 . The negative pressure wound therapy apparatus according to claim 1 , wherein the body comprises an adhesive for fixing the body with respect to the wound site.

6 . The negative pressure wound therapy apparatus according to claim 1 , wherein the connector, the body, and the drape are configured to produce a fluid-tight seal when the connector and the body are attached to each other.

7 . The negative pressure wound therapy apparatus according to claim 1 , wherein the connector is connected to a suction tube.

8 . The negative pressure wound therapy apparatus according to claim 1 , wherein the connector is an integrally formed piece of a semi-rigid material.

9 . A negative pressure wound therapy apparatus comprising:
a manifold comprising a wound-facing side adapted to face the wound site and an outward-facing side opposite the wound-facing side; a connector for providing fluid communication with the manifold, the connector comprising:
a mounting surface adapted to be positioned on the manifold,
a connector body comprising a primary port and an ancillary port, wherein the connector body is configured to directly couple with a conduit,
a port extension including a proximal end, a distal end, and a length extending therebetween, wherein the port extension comprises a sufficient length from the mounting surface to extend into the manifold when the mounting surface is positioned on the manifold,
a reduced pressure source adapted to be positioned in fluid communication with the primary port; wherein:
the manifold is configured to receive a drape over the outward-facing side of the manifold; and
the mounting surface of the connector is adapted to be positioned against an outer surface of the drape over the manifold in an operable state of the negative pressure therapy apparatus.

10 . The negative pressure wound therapy apparatus according to claim 9 , further comprising the drape, wherein the drape is configured to be positioned over the outward-facing side of the manifold.

11 . The negative pressure wound therapy apparatus according to claim 10 , wherein the mounting surface is parallel to the drape in the operable state of the negative pressure therapy apparatus.

12 . The negative pressure wound therapy apparatus according to claim 10 , wherein the drape comprises a semi-permeable material.

13 . The negative pressure wound therapy apparatus according to claim 9 , wherein the length of the port extension is sufficient to extend between the outward- facing side and the wound-facing side of the manifold.

14 . The negative pressure wound therapy apparatus according to claim 9 , wherein the ancillary port is configured to be in fluid communication with atmosphere.

15 . The negative pressure wound therapy apparatus according to claim 9 , wherein the connector body is configured to be connected to a suction tube.

16 . The negative pressure wound therapy apparatus according to claim 9 , wherein the connector body has an opening in a first end region thereof having an inner diameter configured to receive a distal end portion of the conduit.

17 . The negative pressure wound therapy apparatus according to claim 9 , further comprising the drape configured to cover the outward-facing side of the manifold.
