Abstract

An apparatus and method are disclosed for providing a fluid communication path to a wound site through a drape. The apparatus has 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.

Claims

1. An apparatus comprising,

a drape for covering a wound site

a body portion locatable under the drape at the wound site, the body portion providing a fluid communication path to the wound site through the drape, the body portion comprising:

a lower surface and an upper surface, wherein the upper surface is configured to support an overlying region of the drape;

at least one connection port in the upper surface of the body portion, wherein the connection port comprises one of a drape piercing member or a piercing member receptor;

at least one suction port locatable in fluid communication with the wound site; and

at least one fluid communication passageway between the connection port and the suction port;

wherein

a connector at an end of at least one tubular conduit is locatable over the connection port and configured to seal with said connection port to thereby provide a fluid communication path through the drape between said tubular conduit and the wound site, wherein the connector comprises the other of the piercing member or a piercing member receptor.

2. The apparatus as claimed in claim 1 wherein the connection port is located in a top surface region of the upper surface of the body portion.

3. The apparatus as claimed in claim 2, wherein the connection port comprises a swivel connector member to enable the connector to swivel with respect to the body portion when duly connected thereto.

4. The apparatus as claimed in claim 1 wherein the connection port is in a side wall region of the upper surface of the body portion.

5. The apparatus as claimed in claim 1, wherein the body portion comprises an integrally formed portion of resilient material having a type A Shore hardness of greater than around 10 and a type A Shore hardness of less than around 70.

6. The apparatus as claimed in claim 1, wherein:

the connector comprises an integrally formed elongate element of semi-rigid material having a type A Shore hardness of greater than around 90.

7. The apparatus as claimed in claim 1 wherein the connector further comprises a bleed port.

8. The apparatus as claimed in claim 1, wherein:

the upper surface of the body portion comprises at least one indented region configured to aid a user in picking up and locating the body portion over a wound site.

9. The apparatus as claimed in claim 1, wherein the body portion comprises a lip region extending circumferentially around a central raised region and optionally the raised region is round in shape or D-shaped or rectangular.

10. The apparatus as claimed in claim 1, the lower surface of the body portion further comprising an adhesive layer.

11. The apparatus as claimed in claim 1, wherein the connector and connection port are configured to seal to each other via a snap fit connection.

12. A method for providing a fluid communication path through a drape covering a wound site, comprising:

locating a body portion comprising a lower surface and an upper surface, wherein the upper surface is configured to support an overlying region of the drape at a selected location with respect to a wound site;

covering the body portion and wound site with the drape;

locating a connector over a connection port of the body portion and sealing the connector thereto, thereby completing a fluid communication path through the drape between at least one tubular conduit terminated by the connector and a suction port of the body portion in fluid communication with the wound site; and

accumulating drape material between the connector and a region of the connection port when the connector is located in the orifice.

13. The method as claimed in claim 12, further comprising locating the body portion at a central position over wound packer material located in the wound site.

14. The method as claimed in claim 12, further comprising:

locating the body portion in a tracking position with respect to the wound site.

15. The method as claimed in claim 12, further comprising:

removing a cover film from one side of the drape prior to covering the body portion and wound site with the drape and adhering the uncovered one side of the drape to the upper surface of the body portion and a peripheral region extending around the wound site.

16. The method as claimed in claim 12, further comprising locating a drain in the suction port of the body portion.

17. An apparatus comprising:

a drape for covering a wound site;

a body portion locatable under the drape at the wound site, the body portion providing a fluid communication path to the wound site through the drape, the body portion comprising;

a lower surface and an upper surface, wherein the upper surface is configured to support an overlying region of the drape;

at least one connection port in the upper surface of the body portion;

a plurality of suction ports locatable in fluid communication with the wound site, wherein one of the plurality of suction ports comprise a recessed region in the body portion, and wherein an abutment surface region is arranged such that a drain located in an abutting relationship thereto closes another of the plurality of suction ports on the lower surface of the body portion; and

at least one fluid communication passageway between the connection port and the suction port;

wherein

a connector at an end of at least one tubular conduit is locatable over the connection port and configured to seal with said connection port to thereby provide a fluid communication path through the drape between said tubular conduit and the wound site.

18. An apparatus comprising:

a drape for covering a wound site;

a body portion locatable under the drape at the wound site, the body portion providing a fluid communication path to the wound site through the drape, the body portion comprising;

a lower surface and an upper surface, wherein the upper surface is configured to support an overlying region of the drape;

at least one connection port in the upper surface of the body portion, wherein the connection port further comprises a piercing member configured to pierce the drape;

at least one suction port locatable in fluid communication with the wound site; and

at least one fluid communication passageway between the connection port and the suction port;

wherein

a connector at an end of at least one tubular conduit is locatable over the connection port and configured to seal with said connection port to thereby provide a fluid communication path through the drape between said tubular conduit and the wound site.

19. A method for providing a fluid communication path through a drape covering a wound site, comprising:

locating a body portion comprising a lower surface and an upper surface, wherein the upper surface supports an overlying region of the drape at a selected location with respect to a wound site, and wherein the upper surface of the body portion comprises a piercing member for piercing the drape;

covering the body portion and wound site with the drape; and

locating a connector over a connection port of the body portion and sealing the connector thereto, thereby completing a fluid communication path through the drape between at least one tubular conduit terminated by the connector and a suction port of the body portion in fluid communication with the wound site.
