Abstract
A combination wound drain and substance-delivery device includes a drain portion and a substance delivery portion. The drain portion and the substance-delivery portion include interior cavities that are separated from one another to prevent fluids and/or materials disposed within the interior cavities from mixing together. Each of the interior cavities includes one or more perforations that allow fluid communication between a wound site and each of the interior cavities. The device further includes a tip coupled to the drain portion that facilitates removal of collected waste from the drain portion. The device may include an attachment mechanism that helps secure the device when placed within a wound site.
Claims21
A device for combined wound drainage and substance delivery, the device comprising:
- a drainage portion comprising:
- a first end and a second end;
- an interior cavity that extends along a length of the drainage portion;
- a perforation disposed between the first end and the second end and adapted to allow communication of waste between the interior cavity and an area in proximity to an exterior of the drainage portion;
- and
- a tip disposed at the first end that allows waste within the interior cavity to exit the device;
- a substance-delivery portion comprising:
- a first end and a second end, wherein the first end of the substance-delivery portion is adjacent to the second end of the drainage portion;
- and
- an interior cavity that extends along a length of the substance-delivery portion;
- and
- a perforation disposed between the first end and the second end of the substance-delivery portion and adapted to allow fluid communication between the interior cavity of the substance-delivery portion and an area in proximity to an exterior of the substance-delivery portion;
- and
- a wall disposed between the drainage portion and the substance-delivery portion.
A method for removing waste from and delivering a substance to a wound site, the method comprising:
- inserting a substance into an interior cavity of a substance-delivery portion of a device for combined wound drainage and substance delivery;
- inserting the device for combined wound drainage and substance delivery into a wound site;
- wherein the device for combined wound drainage and substance delivery comprises:
- a drainage portion comprising:
- a first end and a second end;
- an interior cavity that extends along a length of the drainage portion;
- a perforation disposed between the first end and the second end and adapted to allow fluid communication between the interior cavity of the drainage portion and an area in proximity to an exterior of the drainage portion;
- and
- a tip disposed at the first end that allows waste within the interior cavity to exit the device;
- a substance-delivery portion comprising:
- a first end and a second end, wherein the first end of the substance-delivery portion is adjacent to the second end of the drainage portion;
- and
- an interior cavity that extends along a length of the substance-delivery portion;
- and
- a perforation disposed between the first end and the second end of the substance-delivery portion and adapted to allow fluid communication between the interior cavity of the substance-delivery portion and an area in proximity to an exterior of the substance-delivery portion;
- and
- a wall disposed between the drainage portion and the substance-delivery portion.
